Podcasts about terahertz

In this talk, I will discuss the applications of cavity electrodynamics for controlling many-body electron systems. The focus will be on achieving strong coupling between cavities and collective excitations of interacting electrons at Terahertz and IR frequencies. As a specific example I will consider a cavity platform based on a two dimensional electronic material encapsulated by a planar cavity consisting of ultrathin polar van der Waals crystals. I will also discuss how metallic mirrors sandwiching a paraelectric material can modify the transition into the ferroelectric state. Finally, I will review a general question of theoretically describing ultrastrong coupling waveguide QED. I will present a novel approach to this problem based on a non-perturbative unitary transformation that entangles photons and matter excitations. In this new frame of reference, the factorization between light and matter becomes exact for infinite interaction strength and an accurate effective model can be derived for all interaction strengths.

Massive bandwidths are available in the sub-terahertz bands, but the coverage of a cellular network exploiting those frequencies will be spotty. The 6GTandem project tries to circumvent this issue by developing a dual-frequency system architecture that jointly uses the sub-6 GHz and sub-THz bands. In this episode, Erik G. Larsson and Emil Björnson are visited by Dr. Parisa Aghdam, Technical Lead of 6GTandem and Research Manager at Ericsson. The discussion starts with potential use cases, such as extended reality services in stadiums and connected factories. The conversation then focuses on hardware aspects, such as how to build a distributed antenna system using plastic microwave fibers and amplifiers so that sub-THz signals can be transmitted from many different locations.

In this episode of the NDE 4.0 podcast, we speak with Michael Pepper about how the how Terahertz technology will impact NDE. We also explore how Teraview's technology relates to other emerging technologies within the NDE sector.

Andiamo all’ENEA per parlare di una nuova tecnologia per il controllo di qualità di alimenti quali le nocciole, una delle eccellenze del settore agroalimentare italiano. Infatti il Laboratorio Applicazioni dei plasmi ed esperimenti interdisciplinari ha messo a punto una tecnologia in grado di individuare rapidamente le nocciole guaste senza sgusciarle, misurandone il contenuto d’acqua. Il sistema si basa su una sorgente e un rivelatore nella banda dei Terahertz, una frazione dello spettro delle onde elettromagnetiche a metà strada tra le microonde e gli infrarossi, per la quale fino a poco tempo fa non esistevano dispositivi in grado di utilizzarla. Ce ne parla Emilio Giovenale, ricercatore ENEA del Laboratorio Applicazioni dei plasmi ed esperimenti interdisciplinari.

Kate Magic talks to Lindy Strong from Wellhub World about Frequency devices. Frequency devices work in a very different way to conventional treatments; each has slightly different benefits but essentially, they are all electric devices which generate energy fields that can affect the body on a profound level, getting to the root of whatever is happening in the cell picture. We are very restricted around what we are allowed to say, and so Lindy's work is especially helpful as she has done all the deep diving and research on this topic which is not widely discussed, and summarises it for us in this interview.

Thank you for joining us for our 2nd Cabral HouseCall of the weekend! I'm looking forward to sharing with you some of our community's questions that have come in over the past few weeks…   Summer: Hi doc! I would love your thoughts on calcium hydroxide or pickling lime, mainly for preserving eggs. Hens naturally slow way down in egg production in the winter so I'm looking for ways to preserve our excess farm eggs during the summer to have in the winter. Preserving the raw eggs in pickling lime is one option and I'm just not sure whether it's a good idea or not! Basically you submerge clean, raw, unwashed, day old eggs or freshly layed eggs in a solution of 1 oz lime to 1 quart water in jars or buckets. They are supposed to be good for up to a year and can be used just like a fresh egg. Just a bit skeptical of calcium hydroxide. Thanks for everything!   Patti: Hi, hope all is well. Any connection with calcium supplements & breast cancer? Thank you   Lacey: Diagnosed with early onset osteoporosis. Was only told I need to go on a pill and that still wouldn't fix it. What are lifestyle tips and steps to take to change this diagnosis??   Noreen: Hello Dr Cabral! Thank you for your commitment to health and well being, and for being such a great educator and practitioner. Have enjoyed your podcast for many years. Question - I have not seen you address or review the Terahertz Healing Wand or Blower. I heard about it earlier this year via the Budwig Center, which I follow, and then recently from a distributor. Gather it has been in the states for a few years and coming into use in alternative health care practices. Should your interest and time permit, would love to hear what you think in a future podcast. God's best to you and yours!   Anonymous: Good Morning Dr. Cabral! I recently had a small leak in my waterline (underground in my front yard) that was going one for around 3 months. During this time, I also noticed that the water coming out of my faucets was slightly cloudy and sometimes had a very subtle bad smell (like rotten eggs). I just had the leak identified and repaired, and the water is much clearer and odorless now. I always filter all drinking/cooking water through my Berkey filter, but while the leak was ongoing I was still exposed to certain unfiltered water (i.e. dishwasher, shower, sink, brushing teeth). My main question: is it possible that something leached into the water supply that could have affected my metabolism? During this time, my metabolism slowed a crazy amount (even though same exercise/diet)    Thank you for tuning into this weekend's Cabral HouseCalls and be sure to check back tomorrow for our Mindset & Motivation Monday show to get your week started off right! - - - Show Notes and Resources: StephenCabral.com/2753 - - - Get a FREE Copy of Dr. Cabral's Book: The Rain Barrel Effect - - - Join the Community & Get Your Questions Answered: CabralSupportGroup.com - - - Dr. Cabral's Most Popular At-Home Lab Tests: > Complete Minerals & Metals Test (Test for mineral imbalances & heavy metal toxicity) - - - > Complete Candida, Metabolic & Vitamins Test (Test for 75 biomarkers including yeast & bacterial gut overgrowth, as well as vitamin levels) - - - > Complete Stress, Mood & Metabolism Test (Discover your complete thyroid, adrenal, hormone, vitamin D & insulin levels) - - - > Complete Food Sensitivity Test (Find out your hidden food sensitivities) - - - > Complete Omega-3 & Inflammation Test (Discover your levels of inflammation related to your omega-6 to omega-3 levels) - - - Get Your Question Answered On An Upcoming HouseCall: StephenCabral.com/askcabral - - - Would You Take 30 Seconds To Rate & Review The Cabral Concept?

How do you teach an AI the difference between a PET bottle and an HDPE bottle? The Bosch team around Sidharta Andalam combined several sources of information to increase the accuracy of their system. Camera images and terahertz sensor signals are combined to decide if an item should get picked out of a waste stream. To get the necessary labeled training data, the engineers used the experience of trained workers at a recycling plant in Singapore. If you haven't listened to the previous full episode about this topic, we recommend starting there for additional context.

Foundations of Amateur Radio Our community is full of TLAs, or three letter acronyms. Some of them more useful than others. For example, I can tell you thank you for the QSO, I'm going QRT, QSY to my QTH. Or, thanks for the chat, I'll just shut up and take my bat and ball and go home. Acronyms arise every day and it came as no surprise to spot a new one in the wild the other day, SHF. It was in a serious forum, discussing antennas if I recall, so I didn't blink and looked it up. Super High Frequency. Okay, so, where's that? I'm familiar with VHF and UHF and as radio amateurs we're often found somewhere on HF, that's Very High Frequency, Ultra High Frequency and High Frequency if you're curious. Turns out that the ITU, the International Telecommunications Union has an official list, of course it does. The current ITU "Radio Regulations" is the 2020 edition. It's great bedtime reading. Volume one of four, Chapter one of ten, Article two of three, Section one of three, Provision 2.1 starts off with these words: "The radio spectrum shall be subdivided into nine frequency bands, which shall be designated by progressive whole numbers in accordance with the following table." When you look at this table you'll discover it starts with band number four and ends with band number twelve, between them covering 3 kHz to 3000 GHz. In position ten you'll see the designation "SHF", covering 3 to 30 GHz, centrimetric waves. A couple of things to note. The list starts at band four. There are of course frequencies below 3 kHz. The list ends at twelve, but there are frequencies above 3000 GHz. You'll also note that I'm not saying 3 Terahertz, since the ITU regulations specify that you shall express frequencies up to 3000 GHz using "gigahertz". Interestingly the same document has a provision for reporting interference where you can report using Terahertz frequencies, so I'm not sure how the ITU deals with such reports. Another thing to note is that this table doesn't actually define what SHF means. It's nowhere in the radio regulations either, I looked. I'm not sure where the words Super High Frequency came from. There is an ITU online database for looking up acronyms and terms. That leads to a document called "Nomenclature of the frequency and wavelength bands used in telecommunications", which also doesn't use "Super High Frequency" anywhere. That said, using the ITU band four, where its definition starts, the VLF band, or Very Low Frequency, followed by LF, Low Frequency, MF, Medium Frequency, the familiar HF or High Frequency, VHF, UHF, then SHF and beyond that, EHF, Extremely High Frequency and THF or Tremendously High Frequency, yes, Tremendously High. There's a report called the "Technical and operational characteristics and applications of the point-to-point fixed service applications operating in the frequency band 275-450 GHz". It introduces the term "THF which stands for tremendously high frequency" but adds the disclaimer that "this terminology is used only within this Report." Seems that there are plenty of documents on the ITU website using that same definition, so I'm guessing that the cat is out of the bag. THF by the way is defined as being for 300 to 3000 GHz frequencies. By the way, the ITU TLA finder exposes that THF stands for Topology Hiding Function. Where's a good acronym when you need it? Speaking of definitions, I came across the definition of a "taboo channel" which according to the ITU is "A channel which coincides with the frequency of the local oscillator in the single super heterodyne receiver which is tuned to an analogue channel." Anyway, we still have a way to go. Below band four, less than 3 kHz, we have ULF or Ultra Low Frequency, SLF, Super Low Frequency and ELF, Extremely Low Frequency, which is defined as band one, between 3 and 30 Hz. Below that, some have suggested TLF, or Tremendously Low Frequency which apparently goes between 1 and 3 Hz with a wavelength between 300,000 down to 100,000 km. Others have suggested that this is an internet meme, but so far it seems to me that it has just as much legitimacy as any of the other wordings, since it appears that the ITU explicitly excludes such definitions, even if internal documents introduce terms from time to time. It did make me wonder, what comes after Tremendously High Frequencies, Red? Turns out, yes, well, infra-red pretty much follows on from Tremendously High Frequencies. If you think that's the end of it, think again. The IEEE, the Institute of Electrical and Electronics Engineers has its own definitions, of course it does. Unfortunately they decided that you need to pay for their standard. It was first issued in 1976 "to remove the confusion". There's an xkcd comic called "Standards", number 927 if you're looking. It goes like this: Situation: There are 14 competing standards. 14?! Ridiculous! We need to develop one universal standard that covers everyone's use cases. Yeah! Soon: Situation: There are 15 competing standards. Anyway, the IEEE designates that after UHF comes L or Long wave, followed by S, or Short wave, then comes C, the compromise between Short wave and X or cross or Exotic. Then there's Ku, Kurtz Under, K, Kurtz, and Ka or Kurtz above, Kurtz being the German word for Short. There's the V band and the W band which follows the V band. Had enough yet? NATO, the EU and the US define these using letters of the alphabet. And broadcasters use Band Numbers which link up to nothing in particular. I wonder if the measure of a society is just how many different ways can be used to describe the same thing. Perhaps we should have stopped at Hertz or Hz, which was established in 1930 by the International Electrotechnical Commission, as an expression of the number of times that a repeated event occurs per second, in honour of Heinrich Hertz. One more three letter acronym, the International Electrotechnical Commission is better known as the IEC. I wonder if the ITU is taking suggestions, ginormous, utterly, inordinately, awfully and humongously seem like perfect opportunities for future expansion. I'm Onno VK6FLAB.

Experimental compound shown to block effects of multiple harmful drugs | New Atlas (01:20) Naloxone is a medication used to reverse or reduce the effects of opioids, which is commonly used to counter decreased breathing in an opioid overdose. A new chemical shows promise for serving a similar role, but it also works on non-opioid drugs.Known as Pillar[6]MaxQ (P6AS) It was developed at the University of Maryland, and it was recently tested on lab animals for the first time. Once P6AS is injected into the bloodstream, it binds with the molecules of certain other compounds and sequesters them into its central cavity, where they're surrounded by an outer layer of water.Altering the bound compound's chemical, physical and biological qualities.Resulting in blocking their effects on the body. In the mice model tests, P6AS proved to be highly effective at mitigating the effects of fentanyl – which is an opioid – but also on methamphetamine, which is not.Additionally it showed to do well at neutralizing non-opioid drugs such as PCP, ecstasy and mephedrone. Captured drug molecules were subsequently passed in the urine It should be noted that in the case of methamphetamine dosing, P6AS had to be injected within five minutes in order to be effective. Would likely be too small of a window in the real world The scientists are now working on lengthening those times, for opioids and non-opioids alike. It'll be several years before P6AS is available for general use.   'Mars' interior is not behaving,' active mantle plume reveals | Live Science (06:30) NASA's InSight mission has detected quakes and even evidence of recent volcanism around one Martian region, known as Elysium Planitia. Now, they think they know why this activity is occuring. This study appears to be the first active mantle plume discovered on the Martian surface.Findings suggest that Mars may be cooling significantly more slowly than scientists had anticipated.  Mars lacks separate tectonic plates; instead, its crust is a single continuous sheet sitting atop the mantle.Therefore scientists think the volcanic activity on Mars must be the result of mantle plumes. Mantle plumes are columns of hot, rising material in the Earth's mantle that can cause volcanic activity and create hotspots on the Earth's surface.Mantle lies between the crust and the core. In short this finding suggests that Mars is still cooling, just more gradually than scientists had assumed. The study concludes by stating:“A plume beneath Elysium Planitia indicates that the surface volcanic flows and seismic activity are not isolated events, but part of a long-lived, actively sustained, regional system, with implications for the longevity and astrobiological potential of subsurface habitable environments.” In other words, the presence of this regional system suggests that there may be areas below the surface of Mars that have conditions that could be suitable for life to exist.   Haptic hydrogel "skin" simulates touch in VR and AR | New Atlas (10:36) Engineers at the City University of Hong Kong have developed a thin, wearable electronic "skin" that provides tactile feedback to users in VR and AR.Called WeTac Most haptic feedback devices are big and bulky, and require complex setups and tangles of wires.WeTac system looks like one of the neatest iterations The system is made of a rubbery hydrogel that sticks to the palm and front of the fingers, connected to a small battery and Bluetooth communication system located in a 5-cm2 (0.8-sq-in) patch on the forearm. That battery can be recharged wirelessly. The hydrogel is dotted with 32 electrodes spread across the palm, thumb and fingers, and electrical currents are sent through these to produce tactile sensations.Can simulate a range of experiences: catching a tennis ball, feeling a virtual mouse walk across your hand, or a negative feedback such as touching a digital cactus. Not interested in the video game applications, but this device could even help users remotely control robots, transmitting the tactile sensation of what the robot is grasping to its human operator.   Pill technology releases molecules by exposure to UV light | Brighter Side News (15:37) Researchers from Tel Aviv University developed a new technology that will allow controlled encapsulation and release of molecules by exposure to UV light. The researchers estimate that the technology will lead to further development of delivery systems for controlled release of biomolecules and drugs in the body by external stimuli, using light. Development was inspired by viral compartments formed by the measles virus.The virus forms compartments that host all the reactions involved in the formation of new viral particles called viral factories. Dynamic and liquid-like structures that are formed inside the host cell The researchers designed a peptide (short minimalistic protein) which forms compartments that resemble viral factories for encapsulation of biomolecules.  Additionally, they incorporated a unique element to the peptide sequence that enables a control of the encapsulation and release of molecules by irradiating the compartments using UV light. Dr. Ayala Lampel, who supervised this study stated on the potential of this technology:“This technology opens opportunities for biomedical and biotechnological applications including encapsulation, delivery and release of drugs, protein, antibodies or other therapeutic molecules.”    A new water-based switch is thousands of times faster than current semiconductors | Interesting Engineering (21:04) Researchers have developed a water-based switch that becomes conductive thousands of times faster than current state-of-art semiconductor-based switches. Used in computers, smartphones, and wireless communications. Transistors are a crucial component in electronic devices because they can control the flow of electricity through a circuit, effectively acting as a switch. The building block of modern electronics, allowing for the amplification and switching of electronic signals. The faster a transistor can switch, the faster a computer system can perform tasks. To create this water-based switch:The researchers used a highly concentrated sodium iodide dissolved water and sprayed this salty water from a custom-made nozzle as a thin sheet only a few microns (micrometers) thick. Next, the water jet was excited with a short but powerful laser pulse at 400 nanometers (nm).This bumps electrons out of the dissolved salts, increasing the conductivity of water. Since the laser pulse is so fast, the water becomes conductive and behaves almost like a metal. All of this happens in less than one trillionth of a second, which translates to potential computer speeds in the terahertz (THz) range.Making this water-based switch faster than the fastest semiconductor switching speed currently known. Terahertz devices could someday enable much faster computing, and water-based technology could offer a more environmentally friendly alternative to rare-earth metals.   

HOPS 361-C's Jet Decelerating and Precessing Through NGC 2071 IR by Adam E. Rubinstein et al. on Thursday 24 November We present a two-epoch Hubble Space Telescope (HST) near-infrared (NIR) study of NGC 2071 IR highlighting HOPS 361-C, a protostar producing an arced 0.2 parsec-scale jet. Proper motions for the brightest knots decrease from 350 to 100 km/s with increasing distance from the source. The [Fe II] and Pa$beta$ emission line intensity ratio gives a velocity jump through each knot of 40-50 km/s. We show a new [O I] 63 $rm mu$m spectrum taken with the German REciever for Astronomy at Terahertz frequencies (GREAT) instrument aboard Stratospheric Observatory for Infrared Astronomy (SOFIA), which give a low jet inclination. Proper motions and jump velocities then estimate total flow speed throughout the jet. We model knot positions and speeds with a precessing jet that decelerates within the host molecular cloud. The measurements are matched with a precession period of a few thousand years and half opening angle of 15$rmdeg$. The [Fe II] 1.26 $rm mu$m to 1.64 $rm mu$m line intensity ratio gives the extinction to each knot ranging from 5-30 mag. Relative to $sim$14 mag of extinction through the cloud from C$^{18}$O emission maps, the jet is well embedded at a fractional depth from 1/5 to 4/5, and can interact with the cloud. Our model suggests the jet is locally dissipated over 0.2 pc. This may be because knots sweep through a wide angle, giving the cloud time to fill in cavities opened by the jet. This contrasts with nearly unidirectional protostellar jets that puncture host clouds and can propagate significantly further than a quarter pc. arXiv: http://arxiv.org/abs/http://arxiv.org/abs/2211.12599v1

Each generation of wireless communications technology has triggered significant and important social and economic changes. The telegraph, the telephone, microwave relays and satellite medications all made distances effectively smaller and local operations national in scale. Wireless is done the same, with each generation of service offering more bandwidth and faster download speeds, enabling new services to develop by the thousands. But each new technology generates a demand for yet more bandwidth, and faster speeds, with less latency. Six G, the next wave of terahertz frequency data transfer, is the next wave. 60 is widely expected to be the critical enabling technology for widespread adoption of VR/AR, the Internet of Things and global scale cloud computing. LG has announced a milestone test of six G transmission over 320 metres outdoors. The test used hardware developed by LG in association with the Fraunhofer Heinrich Hertz Institute in Berlin.

One in a series of talks from the 2019 Models of Consciousness conference. Stuart Hameroff Center for Consciousness Studies, University of Arizona, Tucson, Arizona The Penrose-Hameroff ‘Orchestrated objective reduction’ (‘Orch OR’) theory suggests consciousness arises from ‘orchestrated’ quantum superpositioned oscillations in microtubules inside brain neurons. These evolve to reach threshold for Penrose ‘objective reduction’ (‘OR’) by E=h/t (E is the gravitational self-energy of the superposition/separation, h is the Planck-Dirac constant, and at the time at which Orch OR occurs) to give moments of conscious experience. Sequences, interference and resonance of entangled moments govern neurophysiology and provide our ‘stream’ of consciousness. Anesthetic gases selectively block consciousness, sparing non-conscious brain activities, binding by quantum coupling with aromatic amino acid rings inside brain proteins. Genomic, proteomic and optogenetic evidence indicate the microtubule protein tubulin as the site of anesthetic action. We (Craddock et al, Scientific Reports 7,9877, 2017) modelled couplings among all 86 aromatic amino acid rings in tubulin, and found a spectrum of terahertz (‘THz’) quantum oscillations including a common mode peak at 613 THz. Simulated presence of 8 different anesthetics each abolished the peak, and dampened the spectrum proportional to anesthetic potency. Non-anesthetic gases which bind in the same regions, but do not cause anesthesia, did not abolish or dampen the THz activity. Orch OR is better supported experimentally than any other theory of consciousness. Filmed at the Models of Consciousness conference, University of Oxford, September 2019.

Manhattan reported more UFO sightings than any other borough Article link: https://nypost.com/2018/01/06/manhattan-reported-more-ufo-sightings-than-any-other-borough/ 85 UFO Sightings In New York City Over Past Two Years Manhattan has gone from Studio 54 to Area 51, leading the five boroughs in sightings of unidentified flying objects over the last two years, data from the National UFO Reporting Center reveals. Otherworldly tourists have included travelers in a “round orange orb,” a crew in a “cigar-shaped” craft and even “an unknown creature” that rudely “teleported” into one New Yorker's back yard, according to reports made to the Washington-based group. One Manhattan true believer claimed a close encounter — just by looking outside the gym window. “It was rotating like a drill as it was also moving off axis and in a line towards the east,” the person explained. “As it rotated, you would be able to see four lights that would only be on one side and seen after it fully rotated. It has to be hundreds of feet long. Then after it appeared, four other smaller craft appeared that were to me saucer or spherical that blipped in and out.” In all, there have been 27 spacey sightings in Manhattan since 2016.

Abstract: Terahertz technology has attracted intense interest recently due to its potential applications, from THz spectroscopy and imaging to homeland security. THz sources and detectors are critical for THz applications. Optical parametric process is one of the most promising approaches for tunable monochromatic THz generation and detection for THz applications. In this presentation, Dr. Shi will introduce several innovative results in THz generation and detection. He is the first to observe the THz generation based on DFG using GaSe crystals, and other his other breakthroughs include backward THz generation in GaSe and THz frequency upconversion in GaSe, ZnGeP2 and GaP, respectively. Most recently, Dr. Shi demonstrated fiber-based THz sources for the first time. Several new results about high-power THz generation, based on high power pulsed fiber lasers and some engineered nonlinear crystals, such as QPM-GaP and QPM-GaAs crystals, will be presented. Presented on Thursday, Sept. 15, 2011. Dr. Wei Shi is the director of pulsed fiber laser and THz technology at NP Photonics Inc. He also serves as adjunct professor at College of Optical Sciences at the University of Arizona and supervises graduate students from UA. Dr. Shi received his Ph.D. from State Key Laboratory of Crystal Materials in China and worked in this lab as an associate professor for three years. Dr. Shi has served on the program committee for nonlinear optics for Photonics West since 2008 and the subcommittee for THz technologies and applications for CLEO since 2000. He has served as session chair for CLEO and Photonics West many times since 2008. He is also topic editor for OSA's Applied Optics journal. He has more than 20 years of experience in lasers, nonlinear optics and optical amplifiers research and development. He is a pioneer for the high-power single-frequency pulsed fiber lasers/amplifiers, especially for high SBS-threshold fiber laser/amplifier. Dr. Shi is one of the world leaders for parametric THz generation and detection, especially for fiber-based tunable monochromatic THz sources. He has carried out over $5 million SBIR/STTR projects and other government contracts. He has over 90 journal papers and over 50 conference presentations (including one plenary talk and seven invited talks) at Photonics West, CLEO, OSA and SPIE meetings. Dr. Shi owns two U.S. patents and has three patents filed pending.

The scope of this work is to gain insight and a deeper understanding of exploring and controlling molecular devices like proteins and rotors by fine tuned manipulation via mechanical or electrical energies. I focus on three main topics. First, I investigate vectorial forces as a tool to explore the energy landscape of protein complexes. Second, I apply this method to a biologically important force transduction complex, the integrin-talin complex. Third, I use Terahertz electric fields to manipulate the energy landscape of a molecular rotor on a gold surface and drive their effective rotation bidirectionally. Force is by nature a vector and depends on its three parameters: magnitude, direction and attachment point. Here, the impact of different force protocols varying these parameters is shown for an antibody-antigen complex and the ribonuclease-inhibitor complex barnase-barstar. Antibodies are essential for our adaptive immune system in their function to bind specific antigens. Here, the binding of an antibody to a peptide is probed with varying attachment points. Different attachment points clearly change the dissociation pathways. The barriers identified using experimental atomic force microscopy (AFM) and molecular dynamics (MD) simulations are in excellent agreement. I determine the molecular interactions of two main barriers for each setup. This results in a common outer barrier of the complex and different inner barriers probed by AFM. The ribonuclease barnase and its inhibitor barstar form an evolutionary optimized complex. Different force protocols are shown to determine the hierarchy of relative stability within a protein complex. For the barnase-barstar complex, the internal fold of the barstar is identified to be less stable than the barnase-barstar binding interaction. High velocities probe the lability or barriers of the system while low velocities probe the stability or energy wells of this system. Forces impact biological life on totally different length scales which range from whole organisms to individual proteins. Integrins are the major cell adhesion receptors binding to the extracellular matrix and talin. Talin activates the integrins and creates the initial connection to the actin cytoskeleton of the cell. Here, I have chosen to investigate the integrin-talin complex as a biologically important force transduction complex. The force dependence of the system is probed by constant force MD simulations. The two main results include the activation of the complex and its force response. I demonstrate, that the binding of talin to integrin does not disrupt the integrin's transmembrane helix interactions sterically. Since, this disruption is necessary for integrin activation, a modified activation mechanism requiring a small force application is proposed. The response of the integrin-talin complex normal and parallel to the cell membrane is analyzed. The complete dissociation pathways generated for both directions identify a force-induced formation of a stabilizing beta strand between integrin and talin only for normal forces. Furthermore, the complex tries to rotate such that the external force aligns with the more force resistant axis of the complex. In nature, molecular rotors are essential building blocks of many molecular machines and brownian motors like the F1-ATPase or the flagellum of a bacterium. The direction of rotation often steers different processes in clockwise and counterclockwise directions. Rotation on the nanoscopic level in artificial devices is still very limited and requires a deeper understanding. In my last project, I study the switching and driving of a molecular diethylsulfid rotor on a gold (111) surface by Terahertz electric fields. The response of the rotational energy landscape to static and oscillation electric fields is analyzed. Varying the Terahertz driving frequency, the rotation direction and frequency are controlled. A theoretical framework is presented to describe the behavior of the molecular rotor. This can be seen as the first step into the direction of man-made controllable nano-devices driven and controlled by energy from the electric wall-socket.

With ultrashort pulses of less than 100 fs it is possible to excite coherently several vibrational modes of polyatomic molecules simultaneously. The femtosecond time resolution of the experiment allows the study of pronounced high-frequency beat phenomena up to 10 THz. The frequency difference between vibrational modes separated by more than 300 cm−1 may be determined with high precision.
