Point:
Chirally interactive BioNylons were prepared.
BioNylon showed thermal/mechanical performances than conventional Nylons.
BioNylons disintegrated and degraded with pepsin.
Summary:
Marine plastic waste problems have been more serious year by year. One of the worst issues is that creatures in ocean are going extinct by mistakenly swallowing them.. Conventional biodegradable plastics are degradable in digestive enzymes, but their performances are too low to use in society. In this study, researchers from JAIST have used bio-derived resources such as itaconic acid and amino acid for the syntheses of high-performance BioNylons having the pepsin degradation function.
Researchers Find Way to Boost Life of Batteries Used in Smartphones
Researchers say graphite anodes are the main cause of battery degradation. By Edited by Gadgets 360 Newsdesk | Updated: 5 May 2021 09:32 IST
This could solve a recurring problem for anyone who owns smartphones as batteries degrade over time
Highlights
Their research could have far-reaching consequences
Durable batteries would help those relying on artificial organs
Researchers from the Japan Advanced Institute of Science and Technology have found a way to increase the lifetime of batteries significantly. This could solve a recurring problem for anyone who owns smartphones as batteries degrade over time, the life of a phone is automatically reduced, even if it performs fine in other ways. Scientists say the blame lies mostly with the design of the lithium-ion batteries that power these state-of-the-art smartphones as these batteries degrade over time. Researchers Japan Advanc

A phenomenon of photoexpansion in hard plastic films with a high glass transition temperature in the dry state was established, which was essentially different from very soft actuators, such as elastomers or gels. The photoexpanding hard actuators were expected to apply in the wide fields because they do not contain vaporable matters such as solvents and were much more thermoresistant than conventional ones.

New Copolymer Binder may Lead to Durable Lithium-Ion Batteries
Written by AZoMMar 8 2021
Individuals who have owned a smartphone for more than a year likely know that the integrated lithium (Li)-ion battery does not retain as much charge as it did when the phone was new.

The degradation of such Li-ion batteries is a major concern that considerably reduces the useful life of handheld electronic devices, indirectly resulting in large amounts of economic losses and pollution.
