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...

Researchers from the Qingdao Institute of Bioenergy and Bioprocess Technology (QIBEBT) of the Chinese Academy of Sciences (CAS) proposed a novel bienzyme-catalytic and dioxygenation-mediated mechanism of anthraquinone ring opening.
The study was published in Journal of the American Chemical Society on Sept. 29.
Anthraquinones are a class of ubiquitous natural products in fungi and plants with diverse bioactivities, including anticancer, antiviral, antioxidative and antiinflammatory activities.
Cleavage of the C10-C4a bond of the anthraquinone ring is...

Researchers from the Qingdao Institute of Bioenergy and Bioprocess Technology (QIBEBT) of the Chinese Academy of Sciences (CAS) have proposed a universal methodology framework of GIS-LCA for the first time, which is supposed to greatly improve the standard framework of LCA proposed by the International Standardization Organization (ISO14040). The innovative framework was constructed based on a systematic review of global progress and challenges in GIS-LCA studies.
The life cycle assessment (LCA) is a comprehensive tool to quantify the potential environmental impact, that is, the environmental footprint (ecological footprint, carbon footprint, resource footprint, etc.), from a cradle-to-grave perspective.

Scientists have developed an investigative technique that uses single-cell Raman microspectrometry, which exploits how light interacts with the chemical bonds in a molecule, to derive a dynamic metabolic profile from just one sample rapidly and cheaply. Researchers with the Single-Cell Center, Qingdao Institute of Bioenergy and Bioprocess Technology (QIBEBT) of the Chinese Academy of Sciences (CAS), have developed a fast, low-cost and high-throughput technique capable of profiling dynamic metabol...

Particular , has obvious survival and competitive advantages in the ocean , making it ubiquitous from nutrient-rich coastal waters , low-nutrient oceans , to.Not only an important contributor to ocean carbon fixation and the " biological pump " , but can also directly produce recalcitrant dissolved organic carbon ( RDOC ) via.Significance of Synechococcus , revealing its competitive advantages in the ocean is an important window to understand.Jointly with Professor JIAO Nianzhi , Professor ZHANG Yao from Xiamen University and Professor GAO Shuji from Hainan.
Picophytoplankton, mainly composed of Synechococcus and Prochlorococcus, are the most abundant photosynthetic autotrophs in the ocean, contributing up to 80% of the primary production (carbon fixation) in oligotrophic oceans.
Synechococcus, in...
