Researchers from the Shanghai Institute of Organic Chemistry of the Chinese Academy of Sciences recently developed a new platform for rapid chiral analysis, producing chromatogram-like output without the need for separation.
New research by Carnegie's Olivier Gagné and collaborator Frank Hawthorne of the University of Manitoba categorizes the causes of structural asymmetry, some surprising, which underpin useful properties of crystals, including ferroelectricity, photoluminescence, and photovoltaic ability.
Scientists at the University of Tsukuba create a theoretical carbon-based material that would be even harder than diamond. This work may have industrial applications for cutting and polishing in place of current synthetic diamond.
Scientists at The University of Tokyo and Fudan University researched the process of crystallization in which competing structural forms coexist. By compensating for fluctuations, they were able to more accurately describe the process that determines the final crystalline form. This work may help industrial chemists design new methods.
When two cars collide at an intersection -- from opposite directions -- the impact is much different than when two cars -- traveling in the same direction -- 'bump' into each other. In the laboratory, similar types of collisions can be made to occur between molecules to study chemistry at very low temperatures, or 'cold collisions.' A team of scientists led by Arthur Suits at the University of Missouri has developed a new experimental approach to study chemistry using these cold 'same direction' molecular collisions.
Researchers at Rice University have discovered details about a novel type of polarized-light matter interaction with light that literally turns end over end as it propagates from a source.
A team led by the Department of Energy's Oak Ridge National Laboratory used a simple process to implant atoms precisely into the top layers of ultra-thin crystals, yielding two-sided structures with different chemical compositions. The resulting materials, known as Janus structures after the two-faced Roman god, may prove useful in developing energy and information technologies.
Researchers from the University of Illinois at Urbana-Champaign have developed a new method to improve the noise associated with nanoscale chemical imaging using atomic force microscopy. The improvements will increase the versatility and the precision of the instrument.
In a system with self-replicating molecules -previously shown to have the capability to grow, divide and evolve - chemists from the University of Groningen have now discovered catalytic capabilities that result in a basic metabolism. Furthermore, they linked a light-sensitive dye to the molecules, which enabled them to use light energy to power growth. These findings, which bring artificial life one step closer, were published in the journals Nature Chemistry and Nature Catalysis on 26 June 2020.
Researchers have performed the first room temperature X-ray measurements on the SARS-CoV-2 main protease -- the enzyme that enables the virus to reproduce. It marks an important first step in the ultimate goal of building a comprehensive 3D model of the enzymatic protein that will be used to advance supercomputing simulations aimed at finding drug inhibitors to block the virus's replication mechanism and help end the COVID-19 pandemic.
