Laser Pulses, Class of New Materials Show Potential for Energy Efficiency
An experiment that involves the cutting edge of condensed matter physics and materials science could make superconductivity at room temperature and more efficient energy usage a reality. An international collaboration used tailored laser pulses to snap the electronic interactions in a copper, oxygen and bismuth compound. The scientists identified the condition for which electrons do not repel each other, which is an essential prerequisite for current to flow without resistance.

Unpolarized Single Photons Generated With True Randomness
The generation of single photons in random polarization states from diamond could have significance in the development of quantum cryptography and the testing of fundamental problems in quantum mechanics. Until now, much of the research has been focused on the generation of single photons in pure polarization states.

Nanofiber Device Detects Forces and Sound Waves from Live Cells
A novel nano-sized optical fiber, about 100 times thinner than a human hair, is sensitive enough to detect forces down to 160 femtonewtons (fN) (about ten trillion times smaller than a newton) when placed in a solution containing live Helicobacter pylori bacteria, i.e. swimming bacteria found in the gut. In cultures of beating heart muscle cells from mice, the nanofiber demonstrated the ability to detect sounds down to -30 decibels — a level 1,000 times below the limit of the human ear.

Images Alone Form a Dynamic 3D City Model
“VarCity,” a technology platform that can create 3D city models using image data alone, can evaluate and automatically combine images from all types of sources, including aerial photography, panoramic images taken with special vehicles, and photos published on social networks and internet platforms. It can also use video material, such as from public webcams.

Perovskite Stability Could be Improved by Atomic-Scale Redesign
The mechanism has been discovered that causes solar cells made with organic lead halide perovskites to rapidly deteriorate when exposed to oxygen and light. The discovery could provide the basis for solving issues related to long-term stability of perovskite cells.

Perspectives in 3D Confocal Raman Imaging
Tue, May 30, 2017 11:00 AM - 12:00 PM EDT
This webinar, presented by WITec, will show the workflow and power of confocal Raman imaging for analyzing the chemical composition, crystallinity, stress, optoelectronic and structural properties of materials and organisms. It will introduce state-of-the-art developments in confocal Raman imaging, including user-friendly automated features and the ability to extract information from the data set more easily, leading to improved analyses. It will also cover recording surface topography of rough and uneven surfaces using WITec's TrueSurface technology. A live data evaluation of measured data sets will demonstrate the power of confocal Raman imaging today. Presenter Thomas Dieing, Ph.D., is director of applications and support at WITec GmbH in Ulm, Germany.
