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 amin...

Microalgae, those algae that cannot be seen by the naked eye, produce oil that can be used in biofuel products. These biofuels offer promise as an alternative to conventional fossil fuels, but scientists have lacked a full understanding of the chemical reactions that would allow these microalgae to be useful. A team of researchers have discovered a connection between blue light and oil synthesis in the microalgae. This finding has major implications in the potential for microalgae to be used in the production of biofuels. The research team from the Qingdao Institute of Bioenergy and Bioprocess Technology, Chinese Academy of Sciences, published their findings on 29th March in Nature Communications. Microalgae, algae that cannot be seen by the naked eye, absorb carbon dioxide and produce oils that can be used as biofuels. These biofuels, which can be carbon negative, offer promise as an alternative to conventional fossil fuels. However, the b...

Solar cells can directly convert light energy into electrical energy through photoelectric effect or photochemical effect. Metal halide perovskites solar cells (PSCs) have attracted tremendous attention, owing to their excellent optical and electrical properties. Among these metal halide PCSs, cesium (Cs)-based PSCs are very promising due to excellent thermal stability. However, Cs-based perovskite devices suffer from severe open-circuit voltage loss, which limits the advantage of the wide-bandgap and seriously affects their power conversion efficiency (PCE). To combat these problems, a research team from the Qingdao Institute of Bioenergy and Bioprocess Technology (QIBEBT) of the Chinese Academy of Sciences (CAS) has proposed a strategy to accelerate carrier transport and collection in Cs-based PSCs and improve the device performance. Solar cells can directly convert light energy into electrical energy through photoelectric effect or photochemical effect.
