EPFL chemists have developed a new catalytic method for symmetry breaking. Published in Angewandte Chemie, the method can help synthesize important building blocks for bioactive compounds such as anticancer drugs.
Ultra-deep DNA sequencing of thousands of cells uncovers many competing mechanisms of evolution as a threat to efficient scale-up of biobased chemicals production. Evolution plays an underestimated role in bioprocesses and limits yields much more than previously anticipated.
International solar thermal energy researchers have successfully tested CONTISOL, a solar reactor that runs on air, able to make any solar fuel like hydrogen and to run day or night - because it uses concentrated solar power (CSP) which can include thermal energy storage.
Nobody really likes bargain hot cocoa powder. It's lumpy, it's too thin and it leaves scummy residue behind. But premium hot cocoa mix is too expensive for some imbibers. Fortunately, Reactions is here with some easy kitchen chemistry hacks to turn cheap cocoa mix into a satisfying cold weather pick-me-up.
Many chemical processes run so fast that they are only roughly understood. To clarify these processes, a team from the Technical University of Munich (TUM) has now developed a methodology with a resolution of quintillionths of a second. The new technology stands to help better understand processes like photosynthesis and develop faster computer chips.
An analytical article based on the study of morphologic and chemical composition of particulate matter in motorcycle engine exhaust was published in the respected scientific journal Toxicology Reports. The group of authors was supervised by Aristidis Tsatsakis, a foreign member of the Russian Academy of Sciences and Doctor Honoris Causa of the Far Eastern Federal University, and Kirill Golokhvast, doctor of biology and Provost for Research at FEFU. The study was supported with a grant of the Russian Science Foundation.
Researchers can now remove the anxiety drug Diazepam from recycled water and wastewater, using low-cost titanium dioxide nanofibers. First marketed as Valium, Diazepam is available in hundreds of brands. The drug is one of three benzodiapezines in the World Health Organisation list of essential medicines, but is also widely abused as an addictive prescription drug. In cities running out of water, removing pharmaceuticals from wastewater in a simple, low cost way is becoming a priority.
More than 7,000 miles away from the snowcapped peaks of PyeongChang, scientists from FSU's Department of Chemistry and Biochemistry unlocked a novel strategy for synthesizing a highly versatile molecule called olympicene -- a compound of carbon and hydrogen atoms named for its familiar Olympic ring shape.
Waves are known in many very different forms; as water waves, light waves or sound waves. But studying polycrystalline catalysts, scientists have now found something quite different -- chemical waves. A chemical reaction takes place on the surface of a crystal, which returns periodically to its original state. Fascinating spiral structures form, the movement of which allows to collect information about the characteristics of the individual grains of crystal.
An international team of scientists has developed a water-soluble 'warped nanographene', a flexible molecule that is biocompatible and shows promise for fluorescent cell imaging. The new nanographene molecule also induces cell death when exposed to blue laser light. Further investigation is required to determine how nanocarbons could be used for a range of biological applications, such as photodynamic therapy for cancer treatments.
