Cryo-Electron Microscopy: Imaging the Transitional Forms of Protein-conducting Channels

The lipid-rich membranes of cells are largely impermeable to proteins, but evolution has provided a way through - in the form of transmembrane tunnels. A new study shows in unmatched detail what happens as proteins pass through such a pore. Results were published in the journal Nature.

X-Ray Technology: Observing a Catalyst Surface at Work with Atomic Resolution

By using a novel X-ray technique, researchers have observed a catalyst surface at work in real time and were able to resolve its atomic structure in detail. The new technique, pioneered at DESY's X-ray light source PETRA III, may pave the way for the design of better catalysts and other materials on the atomic level. It greatly speeds up the determination of atomic surface structures and enables live recordings of surface reactions like catalysis, corrosion and growth processes with a time resolution of less than a second. more

Quantum Dots Provide Complete Control of Photons

By emitting photons from a quantum dot at the top of a micropyramid, researchers at Linköping University are creating a polarized light source for such things as energy-saving computer screens and wiretap-proof communications. more
Imaging Ferroelectric Domains

Imaging Ferroelectric Domains

When thin films of ferroelectric materials are grown on single-crystal substrates, they can develop regions of aligned polarization - called "domains" - that often adopt complex patterns. Manipulation of ferroelectric domains can lead to advances in a number of technologies. However, in order to manipulate the domains, it is important to study their natural development. Previous studies have shown that interfacial strain and electrical boundary conditions play a large role. Accurate measurements of the local polarization can help science learn more. By changing the properties of the substrate and the interfaces of the ferroelectric materials, one can control the size and shape of the domains and thus influence the behavior of the material.

AFM-IR: Nanoscale Chemical Analysis with Unprecedented Sensitivity

Researchers in the Department of Electrical and Computer Engineering at The University of Texas at Austin (UT ECE) have demonstrated the ability to perform nanoscale chemical analysis of molecular films with unprecedented sensitivity by detecting molecular photoexpansion. PhD students Feng Lu and Mingzhou Jin led by Prof. Mikhail Belkin successfully acquired high-quality infrared spectra from as few as 300 molecules in ambient conditions and achieved better than 25 nm spatial resolution. These capabilities enable a highly-sensitive nanoscale analytical tool for chemists, biologists and materials scientists. The results were published in Nature Photonics.
