A research team led by Prof. ZHAO Guang from Qingdao Institute of Bioenergy and Bioprocess Technology (QIBEBT), Chinese Academy of Sciences (CAS), developed a high efficiency cell factory to successfully obtain 100% optical purity D-lactate. Plastic is one of the most versatile and widely used materials in the world. However, the traditional petroleum-based plastic has brought severe ‘white pollution’ due to its nondegradability. Approximately 40 million tons of plastic waste is gen...

Prof. CUI Guanglei’s research group from Qingdao Institute of Bioenergy and Bioprocess Technology (QIBEBT), Chinese Academy of Sciences (CAS), prescribed “Medicines” (electrolyte additives) for treating the poor performances effectively of a high-voltage LiNi0.5Mn1.5O4/graphite battery system with high energy density. It was rationally demonstrated that, the two functional additives of tris(trimethylsilyl) phosphite (TMSP) and 1,3-propanediolcyclic sulfate (PCS) could efficiently stabilize solid electrolyte interface (SEI) layers of both electrodes, making the cyclability of this battery system unprecedentedly high. Moreover, a third designed self-extinguishing flame-retardant additive of (ethoxy)-penta-fluoro-cyclo-triphosphazene (PFPN) was introduced for reducing the flammability of the electrolyte, guaranteeing the battery safety to some extent. Nowadays, the utilizations of rechargeable lithium-ion batteries (LIBs) are spreading quickly from small-sized portable electronic devices to large-scale electric transportation tools and renewable energy storage systems. As a result, people's dep...

The research group from Qingdao Institute of Bioenergy and Bioprocess Technology(QIBEBT), Chinese Academy of Sciences(CAS), developed a series of genetic tools for non-model microorganisms like C. thermocellum (J Microbiol Methods; PloS One; Appl Microbiol Biotechnol; Biotechnol Biofuels). They performed directed engineering of cellulosome for the in situ purification of the catalytic domain of Cel48S in one step with high purity and full activity. The global demand of clean fuel is becoming more urgent, especially for the developing nations. The sustainable non-food lignocellulosic biomass is an attractive source for biofuel and biochemical production. However, the high cost, complicated an...

Water shortage is a global issue facing mankind. Natural solar-driven water evaporation process suffers from low efficiency because water is a poor light absorber. Photothermal membrane, able to realize efficient light harvesting and conversion to heat, is an ideal choice to accelerate the water evaporation under the illumination. However, the tedious process and special techniques in surface modification limit the further development in widespread application. Recently, the research team led by Prof. JIANG Heqing from Qingdao Key Laboratory of Functional Membrane Material and Membrane Technology, Qingdao Institute of Bioenergy and Bioprocess Technology (QIBEBT), Chinese Academy of Sciences (CAS), developed a facile and general “Nanomorphology Composite” strategy to fabricate the carbon-based photothermal membrane with controllable surface microstructure using one-dimensional (1D) carbon nanotubes (CNT) and two-dimensional (2D) graphene. Water shortage is a global issue facing mankind. Natural solar-driven water evaporation process suffers from low efficiency because water is a poor light absorber. Photothermal membrane, able to realize efficient light harvesting and conversion to...

Temperature is one of the most important factors for evolution. As the temperature increases, the catalytic activity of the enzyme increases correspondingly, but at the same time, the affinity between the enzyme and the substrate decreases. It has been proved that metal ions enhance the activity, stability and substrate affinity of metal enzymes. However, the role of metal ions-binding amino acids in thermophilic adaptation is not clear. Recently, a research team led by Prof. LI Fuli from Qingdao Institute of Bioenergy and Bioprocess Technology (QIBEBT), Chinese Academy of Sciences (CAS), unraveled the function of metal ions-binding amino acids in improving substrate affinity. Temperature is one of the most important factors for evolution. As the temperature increases, the catalytic activity of the enzyme increases correspondingly, but at the same time, the affinity between the enzyme and the substrate decreases. It ha...

As regards the demand for energy storage batteries, higher energy density and safer property has been the imperative target with the rapid market expansion of electric vehicles and grid-scale storage systems. Among various new battery technologies, rechargeable Mg battery has attracted increasing attention from researchers. Mg anode inherently possesses incomparable superiorities which are high safety, high volumetric capacity, earth-abundant element (the fifth most abundant in the earth crust) and low cost (about 30 times cheaper than Li). Nevertheless, the lack of compatible electrolytes and suitable cathodes has restricted the further development of rechargeable Mg battery. As regards the demand for energy storage batteries, higher energy density and safer property have been the imperative target with the rapid market expansion of electric vehicles and grid-scale storage systems. Among various new battery technologie...
