Welcome back, Scaling UP! Nation. Have you ever wondered about the hidden dangers of biofilm lurking in your water systems? In our latest Legionella Awareness Month episode, we deep dive into the world of biofilm and its critical link to Legionella with our returning expert, Loraine Huchler, President of MarTech Systems. Packed with invaluable insights and practical advice, this episode is a must-listen for anyone in the water treatment industry. Don't miss it! Ever Wondered How Biofilm and Legionella are Connected? "If you have no biofilm, your risk of Legionella is very low." - Loraine Huchler Loraine Huchler provides an insightful explanation of the complex relationship between biofilm and Legionella interacting within cooling water systems. Life Cycle of Legionella: "Legionella is an aerobic bacteria, while the bacteria inside the biofilm might be anaerobic—they don't need oxygen to thrive. Some can even switch between oxygen-loving and anaerobic states. Legionella matures and seeks a higher life form to reproduce, essentially acting as a parasite within the biofilm." Reproduction and Spread: "In cooling water systems, especially comfort cooling systems that operate seasonally, Legionella can reproduce within the biofilm even when systems are idle. The biofilm's thickness increases due to the abundance of bacteria. When the system restarts, the force of the water shears off the top layer of the biofilm, dispersing bacteria throughout the entire chiller system." Challenges in Bacteria Control: Loraine emphasizes, "This scenario illustrates why it's so difficult to control bacteria in cooling water systems. The constant cycle of biofilm formation and disruption means bacteria, including Legionella, are continuously spread and difficult to manage." Implications for Industrial Water Professionals: Understanding this complex relationship is crucial for implementing effective water treatment strategies. Regular monitoring and proactive management of biofilm are essential to mitigate the risks associated with Legionella and maintain system efficiency. How Do You Measure the Amount of Biofilm, and How Does This Measuring Technology Work? "Adding a biofilm sensor will give real-time early detection of biofilm and make precision dosing a reality for biocides which can kill Legionella." - Loraine Huchler Exploring Biofilm Measurement Technologies: Loraine Huchler delves into the intricacies of measuring biofilm, highlighting two key technologies: Electrochemical and Ultrasonic. Ultrasonic Technology: "The ultrasonic technology is novel and proprietary. Currently, only one water treatment company has developed it, and access to this online sensor is limited to their customers. This technology is the only sensor that measures biofilm in an online system. It includes a test chamber with a heated surface and a precisely controlled water flow that matches your most vulnerable heat exchanger. Using ultrasonic technology, it determines the biofilm thickness." Applications and Considerations: Loraine poses an intriguing question: "If you know the biofilm thickness, you could calculate the heat transfer loss in your heat exchangers, potential production loss in a process plant, or increased electrical demand in a chiller plant. However, managing biofilm effectively only requires knowing its presence so you can react. The ultrasonic technology, while sophisticated, is more complicated, expensive, and challenging to use compared to electrochemical sensors." Electrochemical Sensors: "The electrochemical sensors don't require a test chamber, allowing them to be placed in various locations to monitor biofilm. For example, you might choose a sump, a quiet area where the biofilm may not be mobile and may not respond to water treatment dosing." Mechanism and Sensitivity: Loraine explains the mechanism behind biofilm formation: "Quorum sensing is the process where bacteria hover above a surface and assess it before settling. The electrochemical device triggers a signal the moment bacteria sit on the surface, providing an extremely sensitive early warning of biofilm formation." Practical Implications for Water Professionals: Understanding where to place these sensors and how they work is crucial for effective biofilm management. Loraine emphasizes, "This economical and insightful method helps you understand biofilm risks in your cooling water systems, even though I've never seen one in service. It's essential to explore these technologies to monitor biofilm and mitigate its impact on your systems." Actionable Steps for the Scaling UP! Nation.

This audio is brought to you by Wearcheck, your condition monitoring specialist. A far-reaching new drive is under way to ease iridium scarcity still further and, especially in the short term, demand for platinum group metals (PGMs) from electrochemical processes is on the way. That is the news from clean chemistry company Mattiq, which aims to decarbonise chemicals production. The Chicago-based Mattiq is intent on providing low-iridium materials for PGMs-based proton exchange membrane (PEM) electrolysers that generate green hydrogen, the globally recognised enabler of the climate-vital transition to sustainable energy and net zero emission. "When I say low iridium, we're typically talking about say one-third or less iridium by mass," Mattiq product management head Dr Mike Ashley outlined to Mining Weekly in a Zoom interview. (Also watch attached Creamer Media video.) With the aim of making low-iridium materials commercially available in 2025, Mattiq intends to clinch a partnership with a catalyst manufacturing concern in the second or third quarter of this year. "Especially in the short term, we're going to see a pretty significant increase in demand for PGMs from electrochemical processes," said Ashley. Mattiq is developing electrochemical processes that run on clean electricity to decarbonise chemicals production. "For the same reasons that iridium is quite durable over long periods of time in PEM electrolyser applications, other PGMs such as platinum, palladium, rhodium, exhibit similar characteristics where they're active and efficient catalysts, and they're very durable over long periods of time. Fortunately, all those materials are less expensive and not as scarce as iridium," said Ashley. Regarding the softening of PGMs demand from catalytic converters for internal combustion engine vehicles, he said: "We see electrochemistry as a potentially very important substitute demand source for PGMs moving forward." In addition to green hydrogen, Mattiq foresees making many more chemical products in a low-carbon way using electrocatalytic processes. Examples of those chemical products the company sees as being attractive include acetic acid for food and beverage production, adipic acid for nylon production in particular, as well as ethylene glycol, a chemical used in coolant and antifreeze. "These are a few examples of chemicals that are fairly carbon intensive today, that we can help to decarbonise by running through electrochemical processes that are run on clean power," Ashley explained. Mattiq finds that even having small quantities of PGMs in the system can improve durability considerably. "The addition of small quantities of PGMs will always improve the durability of your system in a meaningful way. "We think that the chemical sector is going to be the hardest-to-abate sector of the economy, due to its inherent ties to fossil fuels, leveraging both fossil fuel feedstocks and fossil fuels to run chemical processes, and we think that electrochemistry is a very key part of the decarbonisation strategy of chemical companies across the globe. "We think that electrochemical systems are a very important piece of the puzzle to decarbonisation targets for the major chemical companies across the globe. "We think electrochemistry uniquely allows you to bypass some of the heaviest emitting parts of chemical processing. "Think things like high temperature process heat, compressors to produce high pressure reaction systems, we can completely circumvent these parts of the process by using electrochemical processes. "Simply by running these systems on electricity rather than fossil fuel burners will allow chemical companies to achieve their decarbonisation targets in the coming decades," Ashley emphasised. BIG IRIDIUM FOCUS Highly corrosion-resistant, iridium is the only known material that can last for long periods of operation under harsh acidic and oxidative conditions, which is why it is a key PEM catalyst material. Because it is ...

Link to bioRxiv paper: http://biorxiv.org/cgi/content/short/2023.07.30.551155v1?rss=1 Authors: Bakhshaee Babaroud, N., Rice, S. J., Camarena Perez, M., Serdijn, W. A., Vollebregt, S., Giagka, V. Abstract: In this paper, we present the surface modification of multilayer graphene neural electrodes with platinum (Pt) nanoparticles (NPs) using spark ablation. This method yields an individually selective local printing of NPs on an electrode surface at room temperature in a dry process. NP printing is performed as a post-process step to enhance the electrochemical characteristics of graphene electrodes. The NP-printed electrode shows significant improvements in impedance, charge storage capacity (CSC), and charge injection capacity (CIC), versus the equivalent electrodes without NPs. Specifically, electrodes with 40% NP surface density demonstrate 4.5 times lower impedance, 15 times higher CSC, and 4 times better CIC. Electrochemical stability, assessed via continuous cyclic voltammetry (CV) and voltage transient (VT) tests, indicated minimal deviations from the initial performance, while mechanical stability, assessed via ultrasonic vibration, is also improved after the NP printing. Importantly, NP surface densities up to 40% maintain the electrode optical transparency required for compatibility with optical imaging and optogenetics. These results demonstrate selective NP deposition and local modification of electrochemical properties in neural electrodes for the first time, enabling the cohabitation of graphene electrodes with different electrochemical and optical characteristics on the same substrate.

Kanazawa University NanoLSI Podcast: Enhancing carbon dioxide reductionTranscript of this podcastHello and welcome to the NanoLSI podcast. Thank you for joining us today. In this episode we feature the latest research by Yasafumi Takahashi at the Kanazawa University NanoLSI and Yoshikazu Ito and Yuta Hori at the University of Tsukuba.The research described in this podcast was published in ACS Nano in June 2023Kanazawa University NanoLSI websitehttps://nanolsi.kanazawa-u.ac.jp/en/Enhancing carbon dioxide reductionResearchers at Kanazawa University report in ACS Nano how ultrathin layers of tin disulfide can be used to accelerate the chemical reduction of carbon dioxide — a finding that is highly relevant for our quest towards a carbon-neutral society.Recycling carbon dioxide released by industrial processes is a must in humanity's urgent quest for a sustainable, carbon-neutral society.  For this purpose, electrocatalysts that can efficiently convert carbon dioxide into other, less impactful chemical products are widely researched today.  A category of materials known as two-dimensional (2D) metal dichalcogenides are candidate electrocatalysts for carbon dioxide conversion, but these materials also typically facilitate competing reactions, which compromises their efficiency.  Yasufumi Takahashi from Nano Life Science Institute (WPI-NanoLSI), at Kanazawa University and colleagues have now identified a 2D metal dichalcogenide that can efficiently reduce carbon dioxide to formic acid, a compound that not only occurs naturally but is also an intermediate product in chemical synthesis.Takahashi and colleagues compared the catalytic performance of 2D sheets of molybdenum disulfide and tin disulfide.  Both are 2D metal dichalcogenides, with the latter of particular interest because pure tin is a known catalyst for the production of formic acid.  Electrochemical tests of these compounds revealed that with molybdenum disulfide, instead of carbon dioxide conversion, hydrogen evolution reactions were promoted.  Hydrogen evolution reactions refer to reactions yielding hydrogen, which can be useful when the production of hydrogen gas fuel is intended, but in the context of carbon dioxide reduction it is an unwanted competing process.  Tin disulphide, on the other hand, showed good carbon dioxide reduction activity and suppressed hydrogen evolution reactions.  The researchers also carried out electrochemical measurements for bulk tin dioxide powder, which was found to have less catalytic carbon dioxide reduction activity.So how is tin disulphide facilitating carbon dioxide reduction?To understand where the catalytically active sites are in tin disulphide, and why the 2D material performs better than the bulk compound, the scientists applied a method called scanning electrochemical cell microscopy (SECCM).  SECCM is used as a nanopipette to form the meniscus shape nanoscale electrochemical cell for the surface reactivity sensing probe on the sample.  The measurements revealed that the whole surface of the tin disulphide sheet is catalytically active, not only ‘terrace' or ‘edge' features in the structure.  This also explains why 2D tin disulphide has enhanced activity compared to bulk tin disulphide.Calculations provided further insights into the chemical reactions at play.  Specifically, the formation of formic acid was confirmed as an energetically favorable reaction pathway when using 2D tin disulphide as catalyst.The results of Takahashi and colleagues signify an important step forward towards the use of 2D electrocatalysts in electrochemical carbon dioxide reduction applications.  Quoting the scientists: “These findings will provide a better understanding and desigNanoLSI Podcast website

This week's EYE ON NPI is just in time for Earth Day - it's a new environmental sensor: the ScioSense ENS160 Air Quality Sensor (https://www.digikey.com/en/product-highlight/s/sciosense/ens160-air-quality-sensor) - a digital multi-gas sensor that offers optimum detection of volatile organic compounds (VOCs) and oxidizing gases. This is a 4-in-one sensor that improves on common MOX gas sensors that have become popular on the market, but is still super easy to use. This sensor is the successor to the popular CCS811 (https://www.digikey.com/en/products/detail/sciosense/CCS811B-JOPD500/6569311), which we used for many years and was one of the first embedded MOX sensors on the market. It was quite popular but only had one MOX plate, and has been improved with the introduction of the ENS160. Gas sensors are all essentially resistive sensors, where the exposed silicon has a metal oxide layer (MOX) that is susceptible to ambient gasses. There's a heater element that you need to turn on, then wait until the silicon chunk can react with the air. The resistance changes with the amount of organic compounds in the air and you can measure the resistive differences. (https://en.wikipedia.org/wiki/Electrochemical_gas_sensor) Traditional gas sensors came with 4 pins: two for the heater, and two for the resistor. You have to power the heater, then use a resistor divider or op-amp to read the resistance and back calculate. (https://learn.adafruit.com/gas-sensor-comparison/connect-the-sensor-boards) There's no built-in calibration available, you'll have to figure out what each resistance 'means' in human-friendly terms like AQI or ppm/ppb concentrations. This made a lot of gas sensors difficult to use, and also unreliable without constant upkeep. (https://www.google.com/search?q=alcohol+sensor+calibration) The new generation of MOX gas sensors follow in the footsteps of humidity sensors that were originally just capacitive sensors, but now are fully integrated with instant usable data. The CCS811 was one of the first to do this, a real pioneer. For these types of sensors, the MOX element is hidden inside, and the heater is automatically or digitally controlled. Baseline readings are used to provide home or office-grade calibration where we may care more about changes in readings rather than absolute readings. For example, an office's eCO2 reading has increased over the day from "good" to "poor" - that would indicate a need to turn on an HVAC fan or alert someone to open a window. The ENS160 has 4 different sensor elements, each one will have slightly different MOX doping, which means it will react to different classes of gasses. Which is something to remember: it's not like you can tell which TVOC you're sensing - the whole family of ethanol, methane, acetone, etc. are all going to activate the sensing bodies. Likewise - if you need precision CO2 measurements, nothing beats an NDIR sensor (https://en.wikipedia.org/wiki/Nondispersive_infrared_sensor). But those sensors are also pretty expensive - and don't do TVOC sensing. For basic usage, eCO2 will work just as well and at significant power and cost savings. Likewise, if you need specific TVOC sensing, those will cost a lot more but they are tuned. What we like about the sensor is that it's fully integrated: no firmware blobs or NDAs required which means we were able to get it ported to Python without difficulty.(https://github.com/adafruit/Adafruit_CircuitPython_ENS160/blob/main/examples/ens160_advancedtest.py) There's also an Arduino library published by ScioSense for integration in any C/C++ build. The library supports temperature and humidity compensation as well. If you think the ScioSense ENS160 Air Quality Sensor (https://www.digikey.com/short/mcv97mq2) is a breath of fresh air, then you're in luck because they're in stock right now at Digi-Key for immediate shipment! You can also pick up some of the Adafruit-made breakouts for the ENS160 (https://www.digikey.com/en/products/detail/adafruit-industries-llc/5606/16750376) to get you started fast - our breakout includes regulators and level shifting, so you can drive it from 3 or 5V power and logic. Order today and you'll have them in your hands by tomorrow afternoon.

Abstract: Ultramicroelectrode (UME), or - equivalently - microelectrode, probes are increasingly used for single-cell measurements of cellular properties and processes, including physiological activity, such as metabolic fluxes and respiration rates. Major challenges for the sensitivity of such measurements include: (i) the relative magnitude of cellular and UME fluxes (manifested in the current); and (ii) issues around the stability of the UME response over time. To explore the extent to which these factors impact the precision of electrochemical cellular measurements, we undertake a systematic analysis of measurement conditions and experimental parameters for determining single cell respiration rates, via the oxygen consumption rate (OCR) at single HeLa cells. Using scanning electrochemical microscopy (SECM), with a platinum UME as the probe, we employ a self-referencing measurement protocol, rarely employed in SECM, whereby the UME is repeatedly approached from bulk solution to a cell, and a short pulse to oxygen reduction reaction (ORR) potentials is performed near the cell and in bulk solution. This approach enables the periodic tracking of the bulk UME response to which the near-cell response is repeatedly compared (referenced), and also ensures that the ORR near the cell is performed only briefly, minimizing the effect of the electrochemical process on the cell. SECM experiments are combined with a finite element method (FEM) modeling framework, to simulate oxygen diffusion and the UME response. Taking a realistic range of single cell OCR to be 10e-18 to 10e-16 mol s-1, results from the combination of FEM simulations and self-referencing SECM measurements show that these OCR values are at - or below - the present detection sensitivity of the technique. We provide a set of model-based suggestions for improving these measurements in the future, but highlight that extraordinary improvements in the stability and precision of SECM measurements will be required if single cell OCR measurements are to be realized.

M., Kuo, C.-C., Gardiner, W., Wu, R.-N., Thang, L., Gereau, G., Yuede, C., Cirrito, J., McCall, J. G., Al-Hasani, R. Abstract: The endogenous opioid peptide systems are critical for analgesia, reward processing, and affect, but research on their release dynamics and function has been challenging. Here, we have developed microimmunoelectrodes (MIEs) for the electrochemical detection of opioid peptides using square-wave voltammetry. Briefly, a voltage is applied to the electrode to cause oxidation of the tyrosine residue on the opioid peptide of interest, which is detected as current. To provide selectivity to these voltammetric measurements, the carbon fiber surface of the MIE is coated with an antiserum selective to the opioid peptide of interest. To test the sensitivity of the MIEs, electrodes are immersed in solutions containing different concentrations of opioid peptides, and peak oxidative current is measured. We show that dynorphin antiserum-coated electrodes are sensitive to increasing concentrations of dynorphin in the attomolar range. To confirm selectivity, we also measured the oxidative current from exposure to tyrosine and other opioid peptides in solution. Our data show that dynorphin antiserum-coated MIEs are sensitive and selective for dynorphin with little to no oxidative current observed in met-enkephalin and tyrosine solutions. Additionally, we demonstrate the utility of these MIEs in an in vitro brain slice preparation using bath application of dynorphin as well as optogenetic activation of dynorphin release. Future work aims to use MIEs in vivo for real-time, rapid detection of endogenous opioid peptide release in awake, behaving animals. Copy rights belong to original authors.

In this podcast episode, MRS Bulletin's Stephen Riffle interviews Alessandra Scagliarini, a professor of infectious disease at the University of Bologna, and Beatrice Fraboni, a professor of physics at the Department of Physics and Astronomy at the University of Bologna, about their electrical transistor assay that quantifies SARS-CoV-2 for antibodies. The purpose is to determine vaccine efficacy over time. The device is built with the semiconducting material poly(3,4-ethylenedioxythiophene) polystyrene sulfonate (PEDOT:PSS). The material not only transfers ion signals into electronic signals, but also amplifies it. Without neutralizing antibodies, the virus attacks the cells, causing both macro cracks as well as minor disruptions in the tight junctions of the cells, which the high sensitivity of this device is able to detect. This kind of data is an indirect way to assess whether patient samples have neutralizing antibodies. This work was published in a recent issue of Communications Materials (doi:10.1038/s43246-022-00226-6).

E' l'argomento preferito dei detrattori della mobilità elettrica: l'impatto ambientale legato alla produzione e allo smaltimento a fine vita delle batterie. D'altronde il problema oggettivamente sussiste, ma il mondo della ricerca ne è ben consapevole ed è impegnato a ridimensionarlo il più possibile.Ne sono un esempio ricerche come quella targata Dalhousie University e pubblicata sul Journal of Electrochemical society, in cui viene presentata una variazione delle attuali batterie al litio che potrebbe durare fino a cent'anni prima di essere riciclata. Mentre un'altro studio, targato IIT e università di Genova, ha mostrato come ridurre quasi a zero, nelle attuali batterie al litio, il contenuto di cobalto, elemento critico sia per la sua scarsità sia per impatto ambientale determinato dalla sua estrazione.Vittorio Pellegrini, co-founder Be-Dimensional, Ex direttore dei Graphene Lab dell'IIT

Transition to Performance Medicine: Rooting on the desire to help people, rather than joining hospitals, Dr. Koniver started out in nutritional IVs different from the pharmaceutical models. Born were the Performance Tools.   We've been on the disease side for so long. And now, we can come into our own wellness, optimization side. And they're equally as valuable.   Peptides. Our body makes peptides - strings of amino acids, which are the "building blocks" of proteins. A small-molecule amino acid safe with ultra-rare side effects and is a very powerful tool in creating a cellular environment to push up growth hormone in a reduced level of inflammation.   Stem cells, exosomes, and some biologics. Umbilical cord stem cells are considered live cells for certain use. Exosomes are not considered live cells but can serve the purpose of the use of stemcell as the carrier of messages to the cells or tissues of the body. As a signaling cell like stemcells, it solves the chronic inflammatory state of parts inside our body to effect rejuvenation and regeneration of those that are hard to rejuvenate.   NAD (nicotinamide adenine dinucleotide) is a type of coenzyme found in humans, animals, yeast, and basically all living things. As we age, NAD is depleting, therefore reducing the energy required to function efficiently and so on causing degenerative illnesses like diabetes, cancer, etc.   IV Phototherapy. Light is considered the most efficient form of energy transfer. These lights are absorbed by different molecules in the membranes of the mitochondria. Electrochemical change is created and healing follows.   O-Zone. Traditionally used for healing chronic disease, for healing wounds, for people with chronic fatigue. O-Zone (O3) quickly releases oxygen in the body system, and helps a lot as the most powerful nutrient.  It also helps people to recover from an assault in one's immune system like recovering back from Covid-19.   Ketamine is a medication used to induce loss of consciousness, a kind of anesthesia. It can produce relaxation and relieve pain in humans and animals.   There's a time and place for everything. There's a lot more that we can do to prevent, to make people better. But there is a role for all these amazing advances.

Direct bicarb resorption - Preferential bicarb resorbtion proximally drives passive chloride resorption - Drives active the formate exchanger for chloride resorption- Neurohormonal influence - AT2 drives a lot of Na resorption, primarily in S1 segment - Does not have a net effect on H-CO3 movement - Dopamine antagonizes sodium resorption - Blocks both Na-K-ATPase and - Na H antiporter- Capillary uptake - Starlings. Again - Low hydraulic pressure due to glomerular arteriole - High plasma on oncotic pressure from loss of the filtrate - The two together promote resorption - There maybe movement from interstitial back into tubular fluid (back diffusion) conflicting data- Glomerular tubular balance - The fractional tubular reabsorption remains constant despite changes in GFR (tubular load) - It is essential the GFR is matched by resorption - The rise in capillary osmotic pressure with increased GFR via increased filtration fraction is one mechanism of GT balance - Glomerular tubular balance os one of three mechanisms that prevents fluid delivery from exceeding the resorptive capacity of the tubules - GT balance - TG feedback - Autoregulation - GT balance can be altered if patients are volume overloaded or depleted - Closes this section with a story of a kid born without a brush border - Primacy of sodium in proximal tubule activity - Discusses bicarb resorbtion - There is no Tm for Bicarb as long as volume overload is prevented, in rats can rise over 60! - If you give NaHCO3 you get volume overload and the Tm I about 60 - Glucose - S1 and S2 have high capacity, low affinity glucose resorption - S3 has high affinity 2 Na fo every glucose - Tm glucose is 375 mg/min - For a GFR of 125t that comes out to 300mg/dL - 125 ml/min * 3mg/ml (300 mg/dL) = 375 mg/min - Functionally this is 200 mg/dL due to splay - Urea - Only 50-60 of filtered urea is excreted - Calcium Loop and distal tubule - Phosphate - 3Na-Phosphate high affinity transporters late in proximal tubule - three types of Na-Phos transporters, type 2 are the most important - regulated by PTH and plasma phosphate - PTH suppresses Phos resorption -Metabolic acidosis also reduces phosphate resorption (good to have phosphate in the tubule to soak up H+ - Decreased tubular pH converts HPO42- to H2PO4- which has lower affinity for phosphate binding site - Mg Loop and distal tubule - Uric AcidWhy do I love acetazolamide?- I love the proximal tubule- Many uses- Often forgottenMOA- Inhibit carbonic anhydraseMain effects- Renal: less bicarb reabsorption (ie less H secretion) à more distal Na/bicarb delivery à hypokalemic metabolic acidosis- Brain: reduce CSF production, reduce ICP/IOP, aqueous humor- Pulm: COPDNotes- Tolerance develops in 2-3 days- Sulfonamide derivative- Highly protein bound, eliminated by kidneys Source: Buzas and upuran, JEIMC, 2016S Data:1968 - High altitudeHigh altitude usually results in respiratory alkalosisAcetazolamide – lessens symptoms of altitude sickness (insomnia, headache) which occur because of periodic breathing/apnea1979- NEJM study took 9 mountaineers asleep at 5360 meters à improvement in sleep, improved SaO2 from 72 to 78.7 mmHg, reduce periodic breathing, increased alveolar ventilation (pCO2 change from 37 mmHg to 30.8mm Hg)1950s - Seizures/migrainesCAI reduces pH (more H intracellularly), K movement extracellularly à hyperpolarization and increase in seizure thresholdWeak CAI (Topamax, zonisamide) but not though to be important mechanism of antiseizure effect (topamax enhances inhibitory effect of GABA, block voltage dependent Na and Ca channels)Pulmonary/COPDThought to help with the metabolic alkalosis and as a respiratory stimulant to increase RR, TV, reduce ventilator timeIn 2001 Cochrane review – no difference in clinical outcomes, but did reduce pH and bicarb minimallyDIABLO study (RCT) on ventilated COPD patients – no difference in median duration of mechanical ventilation despite correction of metabolic alkalosisHigh altitude erythropoiesis (Monge disease)First described in 1925 via Dr. Carlos Monge Medrano (Peruvian doctor), seen in people living > 2500-3000 meters (more common in South America than other high altitude areas)Usually chronic altitude sickness with HgB > 21 g/dL + chronic hypoxemia, pHTNAcetazolamide – reduces polycythemia because induces a met acidosis à increases ventilation and arterial PPO2 and SaO2 à blunts erythropoiesis and reduces HCT and improves pulmonary vascular resistanceGI ulcersWhen H2 and PPI available, less useHistory: 1932 – observed alkaline tide, presumed existence of gastric CA (demonstrated in 1939)Acetazolamide was used to inhibit acid secretion in 1960s, ulcer symptoms, with reversible metabolic acidosis, BUT lots of SE (electrolyte losses, used Na/K/Mg salts to help, renal colic, headache, fatigue, etc)Later found H.

Lipids play a vital role in maintaining cellular functions. Altered lipid metabolism is currently considered a hallmark of many diseases, which highlights the importance of the characterization of lipid composition in understanding, diagnosing, and treating pathologies. Discrimination of isomeric species is challenging in lipidomics. In this talk, I will introduce the microdroplet electrochemical methods capable of resolving different types of isomers commonly encountered in lipid samples using electrospray ionization mass spectrometry. The methods take advantage of the voltage-controlled and dramatically accelerated electrochemical derivatization of lipid isomers in microdroplets to achieve structural elucidation. Applications of the electrochemical mass spectrometry methods in real sample analysis will also be included.

Batterien kann man überall um uns herum finden und ich muss gestehen, ich habe Batterien die ganzen Jahren als sowas von selbstverständlich angesehen, dass ich mich diesmal schon fast genötigt gefühlt habe, eine Episode darüber zu schreiben. Besonders da Batterien eigentlich nur mit Hilfe einiger Grundlagen der Chemie funktionieren, nämlich mit Hilfe der sogenannten Redox Reaktionen. Willst du einen Kommentar zu dieser Episode oder zu diesem Podcast abgeben oder hast du einen Vorschlag für ein Thema, dann gibt es zwei Möglichkeiten. Entweder schreibe mir auf Twitter unter @alltagschemieoder schicke mir einfach altmodisch eine email auf chem.podcast@gmail.com.

Abstract: Progress in computational neuroscience towards understanding brain function is challenged both by the complexity of molecular-scale electrochemical interactions at the level of individual neurons and synapses, and the dimensionality of network dynamics across the brain covering a vast range of spatial and temporal scales. Our work abstracts the highly detailed, biophysically realistic 3D reaction-diffusion model of a chemical synapse to a compact internal state space representation that maps onto parallel neuromorphic hardware for efficient emulation on very large scale, and offers near-equivalence in input-output dynamics while preserving biologically interpretable tunable parameters.

In June 2019 Gudrun talked with Serena Carelli. Serena is member of the Research Training Group (RTG) Simet, which is based in Karlsruhe, Ulm and Offenburg. It started its work in 2017 and Gudrun is associated postdoc therein. The aim of that graduate school is to work on the better understanding of Lithium-ion batteries. For that it covers all scales, namley from micro (particles), meso (electrodes as pairs) to macro (cell) and involves scientists from chemistry, chemical engineering, material sciences, electro engineering, physics and mathematics. The group covers the experimental side as well as modeling and computer simulations. Serena is one of the PhD-students of the program. She is based in Offenburg in the group of Wolfgang Bessler (the deputy speaker of the RTG). Her research focusses on End-of-life prediction of a lithium-ion battery cell by studying the mechanistic ageing models of the graphite electrode among other things. Mathematical modelling and numerical simulation have become standard techniques in Li-ion battery research and development, with the purpose of studying the issues of batteries, including performance and ageing, and consequently increasing the model-based predictability of life expectancy. Serena and others work on an electrochemical model of a graphite-based lithium-ion cell that includes combined ageing mechanisms: Electrochemical formation of the solid electrolyte interphase (SEI) at the anode, breaking of the SEI due to mechanical stress from volume changes of the graphite particles, causing accelerated SEI growth, gas formation and dry-out of the electrodes, percolation theory for describing the loss of contact of graphite particles to the liquid electrolyte, formation of reversible and irreversible Li plating. The electrochemistry is coupled to a multi-scale heat and mass transport model based on a pseudo-3D approach. A time-upscaling methodology is developed that allows to simulate large time spans (thousands of operating hours). The combined modeling and simulation framework is able to predict calendaric and cyclic ageing up to the end of life of the battery cells. The results show a qualitative agreement with ageing behavior known from experimental literature. Serena has a Bachelor in Chemistry and a Master's in Forensic Chemistry from the University of Torino. She worked in Spain, the Politécnico de Torino and in Greece (there she was Marie Curie fellow at the Foundation for Research and Technology - Hellas) before she decided to spend time in Australia and India.

Host: Jeff Fox with special guests, Gemma Reguera and Geoffrey Gadd. Gemma Reguera of Michigan State University in East Lansing and Geoffrey Gadd of the University of Dundee in Scotland talk with Jeff Fox about their efforts, to probe some of the electrical properties of materials produced naturally by specific microorganisms. Thus, Geobacter bacteria make protein filaments, called pili, that act as nanowires, transporting 1 billion electrons per second, according to Reguera and her collaborators. Analytic evidence suggests that the electrons move along these proteins by a thermally activated, multistep hopping mechanism, enabling these bacteria to draw electrons from the extracellular milieu. Meanwhile, the fungus Neurospora crassa can transform manganese into a mineral composite with favorable electrochemical properties. The fungal cells produce filaments that take up manganese, which after heat treatment forms structures that have electrochemical properties that are suitable for use in supercapacitors or lithium-ion batteries. The carbonized fungal biomass-mineral composite has excellent cycling stability and retains more than 90% capacity after 200 cycles, according to Gadd and his collaborators.
