Scientists capture images of atoms 'swimming' in liquid

Graphene scientists from The University of Manchester have created a new ‘nano-petri dish’ using a two-dimensional (2D) material to create a new method of observing how atoms move in a liquid. Published in the journal Nature, a team led by researchers based at the National Graphene Institute (NGI) used stacks of 2D materials such as graphene to trap liquids to better understand how the presence of liquids changes the behavior of solids. The team was able to capture images of a single atom ‘swimming’ in a liquid for the first time. These findings could have far-reaching implications for the future development of green technologies such as hydrogen production. When a solid surface comes into contact with a liquid, the two substances change their configuration in response to the proximity of the other. Such atomic-scale interactions at the solid-liquid interface regulate the behavior of batteries and fuel cells for clean electricity generation, as well as determine the efficiency of cle

X-ray light capture for a much lighter space

It can be seen that the surface roughness measured using Atomic Force Microscopy is significantly reduced over a wide range of length scales.

They used Micro Electro-Mechanical System (MEMS) technology, creating intricate patterns in silicon wafers that can direct and collect X-rays. By annealing and polishing, they realized ultra-sharp features that could rival the performance of existing telescopes for a fraction of their weight, at significantly lower launch costs. X-ray astronomy is a vital tool that helps scientists study and classify various celestial bodies that emit and interact with X-rays, i

Scientists capture images of antibodies attacking neuron receptors

Using the UT Southwestern Cryo-Electron Microscopy Facility, researchers have for the first time captured images of autoantibodies bound to nerve cell surface receptors, revealing the physical mechanisms behind neurological autoimmune disease. The findings, published in Cell, could lead to new ways to diagnose and treat autoimmune conditions, the study authors said. “We are entering a new era of understanding how autoimmune diseases work in the central nervous system,” says Colleen M. Noviello, Ph.D., Assistant Professor of Neuroscience at UTSW who specializes in obtaining cryo-electron microscopy (cryo-EM). ) images up to atomic resolution. Dr. Noviello led the research with Ryan Hibbs, Ph.D., Associate Professor of Neuroscience and Biophysics, Effie Marie Cain Scholar in Medical Research, and Investigator Peter O’Donnell Jr. Brain Institute and Harald Prüss of the Universitätsmedizin Berlin. Researchers have studied autoimmune diseases — a class of conditions in which the immune
