Networked polymer gel electrolytes provide wearable batteries with high energy density

http://en.people.cn/n3/2024/0426/c90000-20162287.html https://www.nature.com/articles/s41586-024-07343-x Huishing Peng and colleagues from Fudan University in Shanghai have developed a strategy for designing channel structures in electrodes to incorporate polymer gel electrolytes and to form intimate and stable interfaces for high-performance wearable batteries. As a demonstration, multiple electrode fibres were rotated together to form aligned channels, while the surface of each […]

Advanced brain-machine interface (BMI) shown at 2024 Zhongguancun Forum in Beijing

https://english.news.cn/20240425/331ce62ba74e40908b35e26e89657fd5/c.html The NeuCyber Array BMI System, a brain-machine interface (BMI) system, was unveiled at the opening ceremony of the 2024 Zhongguancun Forum (ZGC Forum)  in Beijing. A video demonstration showed how  a monkey with its hands restrained and soft electrode filaments implanted in its brain, controlled an isolated robotic arm and grasped a strawberry by simply […]

CAS Shanxi Institute of Coal Chemistry develops multiphase rhodium catalyst for propylene hydroformylaion with ultra-high regioselectivity

https://www.nature.com/articles/s41586-024-07342-y https://www.cas.cn/syky/202404/t20240425_5012616.shtml Hydroformylation reaction catalyze the conversion of olefins to aldehydes under carbon monoxide and hydrogen atmosphere, an important way to utilize olefins in high value-added conversion. Globally, more than 10 million tons of olefins are converted at high value through this reaction pathway each year, and rhodium-catalyzed propylene hydroformylation accounts for more than 70% […]

CAS DICP develops high energy-density aqueous battery based on halogen multielectron transfer

https://english.cas.cn/newsroom/research_news/chem/202404/t20240423_660866.shtml https://www.nature.com/articles/s41560-024-01515-9 Traditional non-aqueous lithium-ion batteries have a high energy density, but their safety is compromised due to the flammable organic electrolytes they utilize. Aqueous batteries use water as the solvent for electrolytes, significantly enhancing battery safety. However, due to the limited solubility of the electrolyte and low battery voltage, aqueous batteries typically have lower […]
