Home > Press > Immune system: First image of antigen-bound T-cell receptor at atomic resolution: Antigen binding does not trigger any structural changes in T-cell receptors – Signal transduction probably occurs after receptor enrichment The cryo-EM structure of the fully assembled T-cell receptor (TCR) complex with a tumor-associated peptide/MHC ligand...

Home > Press > Scientists unravel ‘Hall effect’ mystery in search for next generation memory storage devices Abstract:An advance in the use of antiferromagnetic materials in memory storage devices has been made by an international team of physicists. Scientists unravel ‘Hall effect’ mystery in search for next generation memory storage...

Aug 20, 2022 (Nanowerk News) When it goes online, the MAGIS-100 experiment at the Fermi National Accelerator Laboratory and its successors will explore the nature of gravitational waves and search for certain kinds of wavelike dark matter. But first, researchers need to figure out something pretty basic: how to get...

Aug 20, 2022 (Nanowerk News) In a first, a dye-sensitized photocatalyst that facilitates the most efficient solar water splitting activity recorded to date (for similar catalysts) has been optimized by researchers from Tokyo Tech. Their surface-modified, dye-sensitized nanosheet catalyst shows immense potential, as it can suppress undesirable back electron transfer...

Home > Press > Exploring quantum electron highways with laser light: Spiraling laser light reveals how topological insulators lose their ability to conduct electric current on their surfaces. Diagram of an experimental setup at SLAC’s high-power laser lab where scientists used circularly polarized laser light to probe a topological insulator...

Aug 20, 2022 (Nanowerk News) Researchers are optimizing industrial designs to produce more efficient parts using additive manufacturing (AM). AM involves “printing” 3-D metal parts layer by layer. Material made using AM methods that employ lasers can have residual strain resulting from rapid heating and cooling during printing. Heat treating,...

Home > Press > Visualizing nanoscale structures in real time: Open-source software enables researchers to see materials in 3D while they're still on the electron microscope This rendering of platinum nanoparticles on a carbon support shows how tomviz interprets microscopy data as it’s created, resolving from a shadowy image to...

Aug 20, 2022 (Nanowerk News) Cramming multiple pairs of shoes into a vacation suitcase, twisting and flipping them into different arrangements to fit every pair needed, is a familiar optimization problem faced by harried travelers. This same problem is well known to engineers – when given a number of objects...

Aug 20, 2022 (Nanowerk News) Researchers from Tokyo Metropolitan University have successfully enhanced technology to lift small particles using sound waves (Japanese Journal of Applied Physics, "Improved mid-air acoustic tweezers using adaptive phase and amplitude control"). Their “acoustic tweezers” could already lift things from reflective surfaces without physical contact, but...

Home > Press > Researchers design new inks for 3D-printable wearable bioelectronics: Potential uses include printing electronic tattoos for medical tracking applications Researchers at the Gaharwar Laboratory have developed a new nanoengineered bioink for 3D-printable wearable bioelectronics. These 3D-printable devices are electronically active and can monitor dynamic human motion, paving...
