Breakthrough in Z-alkene synthesis: Scientists develop efficient and sustainable method
Z-alkenes are organic compounds with a double bond between two carbon atoms and two substituents attached to the carbon atoms on the same side of the double bond. They are ubiquitous structural components of organic compounds in chemistry and biology.....»»
Ce-doped yttria transparent ceramic: A new ultraviolet-shielding material for extreme conditions
Ultraviolet (UV) radiation can break most of the chemical bonds in organic matter, and prolonged exposure to ultraviolet light can cause significant harm to humans and objects. In response, UV-shielding materials have been developed to fulfill variou.....»»
Astronomers explain rapid formation of organic macromolecules in protoplanetary disks around young stars
An international team of researchers led by the University of Bern has used observation-based computer modeling to find an explanation for how macromolecules can form in a short time in disks of gas and dust around young stars. These findings could b.....»»

Researchers realize multi-heterojunctioned plastics with high thermoelectric figure of merit
Organic thermoelectric materials hold great promise as flexible energy sources for the Internet of Things and wearable electronics. However, their relatively low dimensionless figure of merit (ZT) compared to traditional materials has been a major ob.....»»
Unlocking the aroma secrets of Qujiao 5 chili peppers: A comprehensive VOC analysis
A research team has identified 1,558 volatile organic compounds (VOCs) in the "Qujiao 5" chili pepper cultivar var, highlighting Pyrazine, 2-methoxy-3-(2-methylpropyl)- and 2-Nonenal, (E)- as key flavor compounds in chili fruit......»»
New study simulates gravitational waves from failing warp drive
Imagine a spaceship driven not by engines, but by compressing the spacetime in front of it. That's the realm of science fiction, right? Well, not entirely. Physicists have been exploring the theoretical possibility of "warp drives" for decades, and a.....»»
Ghosts of species past: Shedding new light on the demise of NZ"s moa can help other flightless birds
New Zealand was once home to giant flightless birds called moa. They had grown accustomed to life without predators. So the arrival of humans in the mid-13th century presented a massive—and ultimately insurmountable—challenge to their existence......»»
Raman spectroscopy offers new insights into ionic liquid acidity
Researchers at the University of Liège have for the first time determined the acidity of ionic liquids using Raman spectroscopy, thanks to Hammett acidity functions. This advance promises to revolutionize our understanding and use of these organic s.....»»
Parched Central Valley farms depend on Sierras for groundwater
New research shows that California's Central Valley, known as America's breadbasket, gets as much as half of its groundwater from the Sierra Nevadas. This is significant for a farming region that in some parts relies almost entirely on groundwater fo.....»»
