Abstract:
Glassy materials play an integral role in the modern world, but inherent brittleness has long been the Achilles heel that severely limits their usefulness. Due to the disordered amorphous structure of glassy materials, many mysteries remain. These include the fracture mechanisms of traditional glasses, such as silicate glasses, as well as the origin of the intriguing patterned fracture morphologies of metallic glasses.

New Online Coupled Aerosol Climate Model to Better Understand Aerosol s Climate Effects Details 06 January 2021
Atmospheric aerosols can exert effects on climate, environment and health.
Atmospheric aerosols can exert effects on climate, environment and health. However, due to the lack of comprehensive understanding of the interaction mechanism between the aerosol and cloud, there exists deep uncertainty in the estimation of climatic and environmental effects caused by the anthropogenic aerosol.
The online coupled aerosol climate model is an important tool to reduce the uncertainty and help scientists understand how the aerosol impacts the climate and environment.
Recently, the Institute of Atmospheric Physics (IAP) of the Chinese Academy of Sciences, through long-term cooperation with the National Institute for Environmental Study of Japan, Kyushu University and the Japan Aerospace Exploration Agency, has implemented an aerosol modu

Abstract:
Lithium is an energy-critical element that is considered to be a geopolitically significant resource. However, the supply of lithium may not be enough to meet continuously increasing demand. As a result, scientists are looking for new ways to extract lithium ions.
Bionic idea boosts lithium-ion extraction
Beijing, China | Posted on January 1st, 2021
Ion selective membranes have already been used extensively for water treatment and ion sieving in electrodialysis technology. However, conventional membranes exhibit low and useless Li+ selectivity, making them insufficient for meeting industry requirements.
Chinese scientists have recently made progress in the preparation and application of a bioinspired material that is capable of achieving controlled ion transport and sieving, especially for lithium-ion extraction.
The COVID-19 pandemic has highlighted the need for rapid and accurate nucleic acid detection at the point of care. To meet this need, scientists from the Suzhou Institute of Biomedical Engineering and Technology have developed a novel amplification-free rapid SARS-CoV-2 nucleic acid detection platform based on hybrid capture fluorescence immunoassay (HC-FIA).
