New research suggests that the relatively large crystals used to change several properties of light in lasers -- changes that are crucial for making lasers into practical tools -- might be created by stacking up far smaller, rod-shaped microcrystals that can be grown easily and cheaply.
This article describes spherical tokamak as model for limitless energy.
Chemists at the University of Texas at Arlington have published a new study that indicates that highly variable contamination events registered in and around unconventional oil and gas developments are the result of operational inefficiencies and not inherent to the extraction process itself.
How genes in our DNA are expressed into traits within a cell is a complicated mystery with many players, the main suspects being chemical. However, a new study by University of Illinois researchers and collaborators in China has demonstrated that external mechanical force can directly regulate gene expression. The study also identified the pathway that conveys the force from the outside of the cell into the nucleus.
Chemists at the University of Waterloo have developed a long-lasting zinc-ion battery that costs half the price of current lithium-ion batteries and could help enable communities to shift away from traditional power plants and into renewable solar and wind energy production.
Engineers from MIT and Singapore University of Technology and Design (SUTD) are using light to print three-dimensional structures that 'remember' their original shapes. Even after being stretched, twisted, and bent at extreme angles, the structures -- from small coils and multimaterial flowers, to an inch-tall replica of the Eiffel tower -- sprang back to their original forms within seconds of being heated to a certain temperature 'sweet spot.'
IRB Barcelona researchers publish a review article on the emerging field of drug transporters that have the capacity to reach the brain more efficiently. IRB Barcelona is one of the few centres worldwide with a specific line of research devoted to this field, which brings together chemistry, pharmacy and biomedicine. The article appears on the cover of the journal Chemical Society Reviews.
Nanocatalysis has attracted much attention in the past few years. Functionalized materials with a nano-/submicro-dimension display a significant and dramatically powerful catalytic capability than traditional catalysts in organic chemical reactions due to the increased surface area which they provide and multiple catalytic centers in their structures.
Researchers from the Max Planck Institute for Chemical Ecology found that the specialist moth Heliothis subflexa benefits from secondary plant components by turning the original defensive function of these compounds into its own advantage. Withanolides, which are present in Physalis plants, usually act as immune suppressants and feeding deterrents in insects. Surprisingly, Heliothis subflexa uses these plant defenses as immune-system boosters. Moreover, withanolides protect the moth from harmful effects caused by pathogenic bacteria. The new study demonstrates a unique benefit to host-plant specialization.
Professor Xu Pingyong at the Institute of Biophysics of the Chinese Academy of Sciences recently developed a new type of monomer, RSFP Skylan-NS (sky lantern for nonlinear structured illumination). Professor Xu, in cooperation with Eric Betzig, a researcher and Nobel laureate at HHIM, and Li Dong, formerly a postdoctoral fellow under Dr. Betzig and now a professor at IBP, applied Skylan-NS to their previously developed SR imaging technique, patterned activation nonlinear SIM.
