Published Fast-charging lithium-sulphur batteries on the horizon
(via sciencedaily.com) Original source New research shows that the next generation of lithium-sulphur (Li||S) batteries may be capable of being charged in less than five minutes, instead of several hours as is currently the case.
Published Using light to produce medication and plastics more efficiently
(via sciencedaily.com) Original source Anyone who wants to produce medication, plastics or fertilizer using conventional methods needs heat for chemical reactions -- but not so with photochemistry, where light provides the energy. The process to achieve the desired product also often takes fewer intermediate steps. Researchers are now going one step further and are demonstrating how the energy efficiency of photochemical reactions can be increased tenfold. More sustainable and cost-effective applications are now tantalizingly close.
Published Breakthrough in ultraviolet spectroscopy
(via sciencedaily.com) Original source Physicists achieve major leap in precision and accuracy at extremely low light levels.
Published Printed polymer allows researchers to explore chirality and spin interactions at room temperature
(via sciencedaily.com) Original source A printable organic polymer that assembles into chiral structures when printed has enabled researchers to reliably measure the amount of charge produced in spin-to-charge conversion within a spintronic material at room temperature.
Published Revolutionary method developed for mass-producing polymer solid electrolytes
(via sciencedaily.com) Original source Scientists have unveiled a groundbreaking technique for mass-producing polymer solid electrolytes, crucial components in batteries.
Published A new world of 2D material is opening up
(via sciencedaily.com) Original source Materials that are incredibly thin, only a few atoms thick, exhibit unique properties that make them appealing for energy storage, catalysis and water purification. Researchers have now developed a method that enables the synthesis of hundreds of new 2D materials.
Published New simpler and cost-effective forensics test helps identify touch DNA
(via sciencedaily.com) Original source Research has found a less expensive and easier to use test to learn more about forensic touch DNA. This research has important implications for forensic investigations and being able to identify DNA from a primary contact -- someone who may have committed the crime -- as well as secondary DNA that was inadvertently and indirectly transferred through touch.
Published Revolutionary chronic wound treatment could help millions
(via sciencedaily.com) Original source An effective treatment for chronic wounds that does not involve antibiotics, but an ionised gas to activate a wound dressing, has been developed by a team of international scientists.
Published Sustainable plastics from agricultural waste
(via sciencedaily.com) Original source Scientists have developed a sustainable method to make high-performance plastics from agricultural leftovers, turning them into valuable materials.
Published Molecular simulations of ammonia mixtures support search for renewable fuels
(via sciencedaily.com) Original source Ammonia is an important molecule with many applications. The end product of the famed Haber-Bosch process, it is commonly synthesized to capture nitrogen for fertilizers, and is used for refrigeration, in cleaning products, and in the production of pharmaceuticals. Recently, this modest molecule has also attracted interest as a potential resource for addressing one of today's most pressing challenges -- the need for reliable and abundant renewable fuels.
Published New high-performance solar cell material
(via sciencedaily.com) Original source A new study reports the discovery of an entirely new stable, earth-abundant, high-performance material for solar absorbers -- the central part of a solar cell that turns light into electricity. While identifying new solar materials is typically very time-consuming, the researchers used a unique high-throughput computational screening method to quickly evaluate around 40,000 candidate materials.
Published A simple and robust experimental process for protein engineering

Published Spiral wrappers switch nanotubes from conductors to semiconductors and back
(via sciencedaily.com) Original source By wrapping a carbon nanotube with a ribbon-like polymer, researchers were able to create nanotubes that conduct electricity when struck with low-energy light that our eyes cannot see. In the future, the approach could make it possible to optimize semiconductors for applications ranging from night vision to new forms of computing.
Published Cicadas' unique urination unlocks new understanding of fluid dynamics
(via sciencedaily.com) Original source While most small insects and mammals urinate in droplets, cicadas urinate in jets. Researchers say the finding could be used to create better robots and small nozzles.
Published Design rules and synthesis of quantum memory candidates
(via sciencedaily.com) Original source In the quest to develop quantum computers and networks, there are many components that are fundamentally different than those used today. Like a modern computer, each of these components has different constraints. However, it is currently unclear what materials can be used to construct those components for the transmission and storage of quantum information.
Published Combined microscopy technique catches light-driven polymers in the act
(via sciencedaily.com) Original source Researchers have used tip-scan high-speed atomic force microscopy combined with an optical microscope to observe light-induced deformation of azo-polymer films. The process could be followed in real time, and the film patterns were found to change with the polarization of the light source. The observations will contribute to the use of azo-polymers in applications such as optical data storage, and the approach is expected to be useful across materials science and physical chemistry.
Published How surface roughness influences the adhesion of soft materials
(via sciencedaily.com) Original source A research team discovers universal mechanism that leads to adhesion hysteresis in soft materials. Through a combination of experimental observations and simulations, the team demonstrated that roughness interferes with the separation process, causing the materials to detach in minute, abrupt movements, which release parts of the adhesive bond incrementally. The findings will make it possible to specifically control the adhesion properties of soft materials through surface roughness and will allow new and improved applications to be developed in soft robotics or production technology in the future.
