Among various post-lithium-ion battery technologies, rechargeable magnesium (Mg) batteries utilizing divalent Mg2+ as charge carriers are expected to offer substantial improvements in volumetric energy density and sustainability of batteries, due to the use of earth-abundant, high-capacity and dendrite free Mg metal anode.
Now, a research team led by researchers from the Qingdao Institute of Bioenergy and Bioprocess Technology (QIBEBT), Chinese Academy of Sciences (CAS), have revealed an unheeded failure mechanism of Mg metal anode, which promotes the development of Mg metal anode battery from a new perspective.

Researchers from the Qingdao Institute of Bioenergy and Bioprocess Technology (QIBEBT) of the Chinese Academy of Sciences (CAS) and their collaborators have developed an instrument called Clinical Antimicrobial Susceptibility Test Ramanometry for Helicobacter pylori (CAST-R-HP), which holds promise as a powerful new tool in the diagnosis and treatment of H. pylori infections. Helicobacter pylori (H. pylori), the bacteria that can cause human gastritis, peptic ulcers and stomach cancer, infects about half of the world’s population. It is essential to quickly identify the infection and select the right combination of se...

Recently, a research team led by Prof. WANG Guanghui from the Qingdao Institute of Bioenergy and Bioprocess Technology (QIBEBT) of the Chinese Academy of Sciences (CAS) has fabricated a novel UiO-66/MS filter and assembled it into an all-in-one device for continuous phosphate removal from wastewater.
Metal-organic frameworks (MOFs) are promising as adsorbents for pollutants removal due to their high surface area, low density, tunable porosity and potential for increased adsorption capacities.
However, MOFs are often synthesized as fin...

Children are easily to become a vehicle for germs with less than perfect hygiene habits and a penchant for putting their hands and toys in their mouths.
In a first-of-its-kind analysis of two kindergartens in China, researchers determined the proportion and species of microbes across a variety of surfaces and children’s palms. The most active sites, and likely routes of transmission, were the kids’ hands — which the researchers found could possibly harbor more pathogens than the bathroom floor.

Hollow structured nanomaterials have drawn increasing interest in the fields of adsorption, catalysis, energy storage and drug delivery/controlled release, owing to their unique properties such as high porosity, large surface area and abundant inner void space. However, in few unique applications where a large species (e.g., dye molecules, proteins) is involved, the complete hollow shell of the hollow nanomaterials mainly acts as a barrier to limit the mass transfer of the large species and result in the unavailable void spaces.

Recently, a research team led by Prof. WANG Guang-Hui from Qingdao Institute of Bioenergy and Bioprocess Technology (QIBEBT) of the Chinese Academy of Sciences (CAS) reported a facile strategy to synthesize two carbon-doped Ni catalysts with particle sizes of 7.5 and 47.5 nm, respectively, over which the selectivity in the reductive amination of biomass-derived carbonyl compounds is completely switched between primary amines (>96% yield, 7.5 nm) and secondary imines (>97% yield, 47.5 nm).
Primary amines and secondary imines are key intermediates widely used in fields like food additives, pharmaceuticals, and agrochemicals. They can be produced via the reductive amination of carbonyl compounds.
However, during the reductive...
