    Researchers Improve Performance of All-solid-state Lithium-sulfur Batteries

    Recently, researchers led by Prof. WU Jianfei from the Qingdao Institute of Bioenergy and Bioprocess Technology (QIBEBT) of the Chinese Academy of Sciences have made a breakthrough in defect engineering and performance improvement of ASSLSBs. They prepared porous-carbon nanotubes (P-CNTs) that are used as sulfur-bearing matrix, forming S@P-CNTs-based composite cathodes for ASSLSBs. P-CNTs acted as a mediator and established a stable triple phase between sulfur, P-CNTs, and ionic conductor solid-state electrolyte (SSE) Li6PS5Cl.
      All-solid-state lithium–sulfur batteries (ASSLSBs) are considered one of the most promising next-generation energy storage devices for high energy density, high safety, and low cost of sulfur.

    Constructing PtFe Alloy Catalysts through Hybrid Mesoporous Fe-N-C Nanostructure

    Researchers from the Qingdao Institute of Bioenergy and Bioprocess Technology (QIBEBT) of the Chinese Academy of Sciences (CAS) and their collaborators have fabricated highly dispersed PtFe nanoparticles loaded on mesoporous Fe-N-C using mesoporous hybrid Fe-N-C as a model support through the in-situ alloy strategy.
      Pt-based intermetallic alloys with high activity and stability are promising for accelerating the cathodic oxygen reduction reaction (ORR) and large-scale application of proton exchange membrane fuel cells.
      Atomically dispersed Fe-N-C cat...

    Novel Mechanism for Oxygen Evolution Reaction on Dual-atom Catalysts Increases Reaction Activity

    Recently, a research team led by Prof. SUN Xiaoyan from the Qingdao Institute of Bioenergy and Bioprocess Technology (QIBEBT), Chinese Academy of Sciences (CAS), with a focus on the oxygen evolution reaction (OER), have provided pivotal mechanistic insights into the role of oxygen coupling between dual active sites during OER.
      Atomically precise cluster catalysts bridge the gap between homogeneous and heterogeneous catalysis, facilitating comprehensive elucidation of structure-activity relationships in catalytic processes. However, the synergistic effects between n...

    Observation of Protein Conformational Dynamics in Live cells

    Recently, a research team from the Qingdao Institute of Bioenergy and Bioprocess Technology (QIBEBT) of the Chinese Academy of Sciences (CAS) has investigated the protein loop conformational dynamics in Escherichia coli ( E.coli ) cells by Nuclear Magnetic Resonance (NMR) Spectroscopy.
      Protein dynamics through motions of loops, linkers, and hinges can generate distinctive conformations that are important for protein function.
      For example, protein folding, recognition, conformation, and enzyme catalysis are all related t...

    Bacterial Signaling Autoproteolysis Confirmed in C. thermocellum

    Transmembrane signaling involves sensing and communicating with the extracellular environment, which is of utmost importance when it comes to cell survival. Part of the transmembrane signaling is a process known as autoproteolysis, which is key in different functions of a cell such as signal transduction in eukaryotes and protease maturation in prokaryotes. In this process a peptide chain, which is a string of amino acids, is cleaved at a specific site by the peptide itself. This is typical of eukaryotes, though a defined, functional autoproteolytic event for transmembrane signal transduction has not been seen in bacteria until now.

    Bacterial Single-cell Whole Genome Sequencing Overhauled by Eengineered Polymerase

    Sequencing the genome of single cells has long been technically difficult and cursed by seemingly incorrigible bias in the gene amplification stage of the process, making it almost impossible to carry out research on rare cell types such as circulating tumor cells. A new process, however, radically reduces that bias, opening up whole new vistas of single-cell research.
