Tiny fragments of plastic waste are dispersed throughout the environment, including the oceans, where marine organisms can ingest them. However, the subsequent fate of these microplastics in animals that live near the bottom of the ocean isn't clear. Now, researchers report in ACS' Environmental Science & Technology that lobsters can eat and break down some of this microplastic material, releasing even smaller fragments into the water that other deep-sea organisms could ingest.
As reel-to-reel tapes make a comeback among audio buffs, scientists are unraveling the secret of why some decades-old tapes are unplayable, while others retain their original superb audio fidelity. The researchers are presenting their results through the American Chemical Society SciMeetings online platform.
Researchers at the University of Pittsburgh and Harvard University designed a polymer known as a liquid crystal elastomer (LCE) that can be 'programmed' to both twist and bend in the presence of light. Especially in the field of soft robotics, this is essential for building devices that exhibit controllable, dynamic behavior without the need for complex electronic components.
Can we tell with the naked eye if any cold-chain food products that we have received have gone bad? A cold-chain safety sticker was developed, which indicates whether any cold-chain food products, such as fish, meat, and fruits and vegetables, have spoiled. This cold-chain safety sticker creates an image on it when exposed to room temperature. Room temperature exposure history and time throughout the cold chain delivery process are indicated but cannot be manually edited.
Researchers at Yokohama National University (YNU) meticulously examined cellulose nanofibers extracted from spent coffee grounds, identifying them as a viable new raw source. The YNU team, led by Izuru Kawamura, an associate professor at the Graduate School of Engineering Science, set out to build upon previous research into extracting cellulose nanofibers from coffee grounds. They published their findings on April 1 in the journal Cellulose.
Researchers at Linköping University, together with colleagues in China, have developed a tiny unit that is both an optical transmitter and a receiver. "This is highly significant for the miniaturisation of optoelectronic systems", says LiU professor Feng Gao. The results have been published in Nature Electronics.
Researchers in Japan have succeeded in creating a new type of helicoidal supramolecular polymer. The process and mechanism of the generation of its structure were observed using atomic force microscopy (AFM); the helicoidal structure grew spontaneously after two different monomers were mixed. The findings of the study, which was published in Nature Communications on April 1st, 2020 may lead to the design of original soft materials.
At the BESSY II storage ring, a team has shown how the helicity of circularly polarized synchrotron radiation can be switched faster - up to a million times faster than before. They used an elliptical double-undulator developed at HZB and operated the storage ring in the so-called two-orbit mode. This is a special mode of operation that was only recently developed at BESSY II and provides the basis for fast switching.
In new research published in EPJ Plus, a team of mathematicians show that by modelling meat as a fluid-saturated matrix of elastic proteins, which are deformed as the fluid moves, cooking behaviours can be simulated more precisely.
Researchers at Linköping University, working with colleagues in Great Britain, China and the Czech Republic, have developed a perovskite light-emitting diode (LED) with both high efficiency and long operational stability. The result has been published in Nature Communications.
