Plastics recycling is complicated by the need to recycle similar plastics together. The presence of flame retardants in plastics also needs to be identified, and a NIR hyperspectral imaging method to do so is reported in this paper in the peer-reviewed, open-access journal, JSI -- Journal of Spectral Imaging.
After slowly forming stars for the first few billion years of their lives, the Magellanic Clouds, near neighbors of our own Milky Way galaxy, have upped their game and are now forming new stars at a fast clip. This new insight into the history of the Clouds comes from the first detailed chemical maps made of galaxies beyond the Milky Way.
Graphene Flagship researchers reviewed the current research into the safety of graphene and related materials looking at both human health and environmental impact.
Climate change causes an increase in the number of freshwaters that run dry, at least temporarily. Around 90,000 square kilometres of water surface have already vanished in the last 30 years. This trend is not only a threat to drinking water reserves and major ecosystems - dried freshwaters also play an important role in the global carbon cycle. Two recently published studies reveal that the importance of this phenomenon has so far been underrated.
Scientists of the Far Eastern Federal University, together with Russian and foreign colleagues, developed samples of nickel mesoporous film structures, which have useful surface area up to 400 times greater than their solid one. Brand new material can be used in energy saving, chemical industry and other practical areas. The research results are published in Applied Surface Science journal.
Carbon fiber is an important structural material of the 21st century. Due to its high strength, which is not inferior to metal alloys, in combination with low specific weight and high oxidative stability, it is an indispensable material for airspace and shipbuilding industry, construction, medicine, sports industry, and in other high-tech industry sectors.
A KAIST team presents a noninvasive light-sensitive photoactivatable recombinase suitable for genetic manipulation in vivo. The highly light-sensitive property of photoactivatable Flp recombinase will be ideal for controlling genetic manipulation in deep mouse brain regions by illumination with a noninvasive light-emitting diode. This easy-to-use optogenetic module made by Professor Won Do Heo and his team will provide a side-effect free and expandable genetic manipulation tool for neuroscience research.
A team of chemists at the University of Münster led by Professor Frank Glorius have developed a new, simple synthetic method for producing fluorinated piperidines -- which had previously been very difficult. These compounds play a major role in the development of new active ingredients. The results have just been published in the online edition of the journal Nature Chemistry.
Modifications made to perovskite solar cells, or PSCs, render them more stable and scalable than ever before.
A new method to measure the temperature of atoms during the explosive death of a star will help scientists understand the shock wave that occurs as a result of this supernova explosion.
