Lithium-ion batteries are relatively safe, long-lasting, fast charging and better for the environment than non-rechargeable batteries — right? Not quite. The ion exchange mechanism that allows for power storage uses rare earth elements, such as nickel and cobalt. Researchers have long been on the hunt for alternative batteries that boast all the benefits of lithium-ion versions but include ecological and economic advantages. Now, a team is closing in on an improved approach. Lithium-ion batteries are relatively safe, long-lasting, fast charging and better for the environment than non-rechargeable batteries–right? Not quite. The rocking-chair mechanism that allows for commercial power storage generally uses rare earth...

Researchers from the Qingdao Institute of Bioenergy and Bioprocess Technology (QIBEBT) of the Chinese Academy of Sciences (CAS) revealed the transcriptional regulation mechanism of pectin biosynthesis.
Pectin is a complex cell wall polysaccharide. It plays an important role in modulating cell adhesion, cell morphogenesis and growth.
Although several genes involved in pectin biosynthesis have been identified, the transcriptional regulatory me...

Recently, a research team from Qingdao Institute of Bioenergy and Bioprocess Technology (QIBEBT), Chinese Academy of Sciences (CAS), has investigated the protein electrostatic interactions in E. coli cells by Nuclear Magnetic Resonance Spectroscopy.
The study, published in Journal of the American Chemical Society on November 12.
Electrostatic interaction plays a vital role in many important biological reactions, such as enzyme catalysis, protein-protein interaction, protein-DNA/RNA interaction, and H+ transfer.
Most proteins perform their functions in cells. The compl...

Capacity degradation from highly reactive species of oxygen and free radicals has long bedeviled development of a next generation lithium batteries that use cathodes composed of layers of transition metal oxides. A new technique inspired by how living organisms deal with a similar problem appears to have now solved it for batteries too. For high-voltage lithium batteries using layered transition metal oxide cathodes, the chemical degradation of the battery's electrolytes results in rapid decay of its capacity, which poses substantial challenges to practical applications of this p...

Researchers from the Qingdao Institute of Bioenergy and Bioprocess Technology (QIBEBT) of the Chinese Academy of Sciences (CAS) have developed a confined thermal transformation strategy to synthesize nitrogen-doped mesoporous carbon nanospheres (NMCS) supported SACs.
Carbon-supported single-atom catalysts (SACs) are promising in heterogeneous catalysis due to their high atomic utilization efficiency and unique catalytic performances.
However, maximum utilization of the carbon-supported single atoms is very...
