Podcasts about Calorimetry

Ever wonder how scientists measure the intensity of a fire? Join us on this episode as we invite Dr. Matt Bundy from NIST. We discuss the intricacies of heat release rate, calorimetry, and how NIST is championing open data with their astonishing database.You can learn more about the database here: https://www.nist.gov/blogs/taking-measure/new-nist-fire-calorimetry-database-available-answer-your-burning-questionsAnd find the database here: https://www.nist.gov/el/fcdI've tried to make this conversation for everyone. If you never saw a calorimeter or have no idea how to measure fire, from this episode you will learn probably all you need to know. If you know everything about calorimetry, there is a ton of golden nuggets on how NIST runs their experiments, that are absolutely worth listening too.In the podcast episode, we start deciphering the art of measuring fire characteristics - from using heat flux gauges, oxygen and mass loss calorimetry and what are the challenges to each of them.  We then explore the NIST Fire Calorimetry Database, unveiling its evolution from a humble set of data to an open-access resource. Dr. Bundy shares invaluable insights into the development of this enriching database, which has metamorphosed into an extensive video collection system that records fire experiments. He also whets our curiosity about the potential expansion and collaborations lying on the horizon for this unique database. Rounding off our discussion, we delve into the inner workings of the hosting process of the NIST Calorimetry Database, its data storage methods, and how it facilitates easy access to experiments. We also glimpse the future of fire studies as Dr. Bundy calls on the Fire Science Show community to suggest objects to burn for their calorimetry.

Abstract: Tepsin is an established accessory protein found in Adaptor Protein 4 (AP-4) coated vesicles, but the biological role of tepsin remains unknown. AP-4 vesicles originate at the trans-Golgi network (TGN) and target the delivery of ATG9A, a scramblase required for autophagosome biogenesis, to the cell periphery. Using in silico methods, we identified a putative LC3-Interacting Region (LIR) motif in tepsin. Biochemical experiments using purified recombinant proteins indicate tepsin directly binds LC3B, but not other members, of the mammalian ATG8 family. Calorimetry and structural modeling data indicate this interaction occurs with micromolar affinity using the established LC3B LIR docking site. Loss of tepsin in cultured cells dysregulates ATG9A export from the TGN as well as ATG9A distribution at the cell periphery. Tepsin depletion in a mRFP-GFP-LC3B HeLa reporter cell line using siRNA knockdown increases autophagosome volume and number, but does not appear to affect flux through the autophagic pathway. Re-introduction of wild-type tepsin partially rescues ATG9A cargo trafficking defects. In contrast, re-introducing tepsin with a mutated LIR motif or missing N-terminus does not fully rescue altered ATG9A subcellular distribution. Together, these data suggest roles for tepsin in cargo export from the TGN; delivery of ATG9A-positive vesicles at the cell periphery; and in overall maintenance of autophagosome structure.

Despite being the gold standard for estimating energy needs, indirect calorimetry is rarely used by most dietitians. In fact, indirect calorimetry is often reserved for complex clinical situations or for ultra-tailored nutrition prescriptions. The usefulness of indirect calorimetry in most clinical settings is still debated. Join us for the low-down on this elusive technique.

Damian is on LinkedIn at https://www.linkedin.com/in/damiandstefanczyk/ We mention a few terms in this episode that you might want to understand a bit better: -The chemical ‘MDI’, which stands for Methylenediphenyl diisocyanate. MDI is often used in the production of rigid insulation for homes and other building. In different forms, it is also used in sealants, adhesives and weather-resistant materials. If you want to jump all the way down this rabbit hole – then check out this resource on this class of chemicals - https://dii.americanchemistry.com/Diisocyanates-Explained/ -Heat capacity. Heat capacity is a property of all matter. It refers to the amount of heat that needs to be supplied to a material to raise the temperature of the material. The SI unit of heat is Joules per degree Kelvin. Simply put, materials with a lower heat capacity will warm up with less external heat input that materials with higher heat capacity. -Calorimetry. This is the science of measuring the temperature changes of material under certain conditions. In our discussion, we talk about the specific technique of Adiabatic reaction calorimetry, which mimics a situation where no heat is lost from the material under examination. – this allows investigation of potentially unwanted (hazardous) events happening). -Phi factor. The Phi factor is an adjustment used during adiabatic calorimeter experiments. As a reaction proceeds, the calorimeter will absorb some of the heat generated by the reaction. The Phi factor describes how much more heat needs to be added to the calorimeter to mimic a true adiabatic system. The lower the Phi factor, the less external heat needs to be added and therefore, the more closely the experiment mimics the real reaction.

Whew! I completed this podcast using the touchpad on the laptop. It's a MESS but it wil get the point across.

A method for the determination of relaxed silicate liquid molar volume and expansivity at temperatures just above the glass transition is discussed. The method involves the comparison of heat capacity and molar expansivity in the glass transition region. Glassy and liquid heat-capacity data are obtained using differential scanning calorimetry, and glassy thermal expansion data are obtained using scanning dilatometry. The molar expansivity of the liquid is calculated by a fictive temperature normalization of the relaxation behavior of both the heat capacity and the molar expansivity in the glass transition region, with the normalized heat capacity curve being used to extend the dilatometric data into the liquid temperature range. This comparison is based upon the assumed equivalence of the parameters describing the relaxation of volume and enthalpy. The molar expansivity of relaxed sodium trisilicate (Na2Si3O7) has been determined in this manner at temperatures above the glass transition temperature. This low-temperature determination of liquid molar expansivity has been tested against high-temperature liquid expansivity data obtained from high temperature Pt double bob Archimedean buoyancy measurements. The low-temperature molar expansivity (26.43±0.83xl0~4 cm3 mole"lβC_1 at 540°C) determined in this manner agrees within error with the high-temperature molar expansivity (23.29±1.39xl0~4 cm3 mole^ºC1 at 1400°C). This dilatometric/calorimetric method of liquid molar expansivity determination greatly increases the temperature range accessible for thermal expansion measurements. A weighted linear fit to the combined low and high temperature volume data gives a molar expansivity of 23.0010.25x10^ cm3 mole^ºC"1. The volume-temperature relationship thus derived reproduces the measured volumes from both dilatometry and densitometry with a RMSD value of 0.033 cm3 mole"1 or 0.14%. This represents a substantial increase in precision, which is especially important for liquids whose high liquidus temperatures restrict the temperature range accessible to liquid volume determinations.
