Lithium ion capacitors are hybrid electrochemical energy storage devices which combine the intercalation mechanism of a lithium ion battery with the cathode of an electric double-layer capacitor. Researchers from QIBEBT have developed high performance capacitors using graphene based composites as electrodes, and applied them to electric bicycles. Lithium ion capacitors (LICs) are hybrid electrochemical energy storage devices which combine the intercalation mechanism of a lithium ion battery with the cathode of an electric double-layer capacitor (EDLC). LICs are quite suitable for applicati...

Glucosylglycerol has a range of potential applications in health, pharmacy and cosmetics due to its physiological, protein-stabilizing and antioxidative properties. In addition to chemical synthesis and enzymatic catalysis, it can be produced as a protective osmolyte in salt-stressed bacteria, such as the cyanobacterium Synechocystis sp. PCC 6803. However, the hurdle of low efficiency and high cost makes the scalable production difficult. QIBEBT researchers have reported an efficient glucosylglycerol production and secretion by genetically modified and encapsulated Synechocystis cells grown in a semi-continuous manner. Glucosylglycerol (GG) has a range of potential applications in health, pharmacy and cosmetics due to its physiological, protein-stabilizing and antioxidative properties. In addition to chemical synthesis and enzymatic catalysis, GG can be produced...

There is an urgent need to solve the safety problems of lithium ion battery (LIB) for application in electric vehicles and power storage. The commercial separators suffer from poor dimensional thermo-stability, flammability and poor wettability. Professor CUI Guanglei and his group from QIBEBT has carried out the interface study on key materials to improve the electochemical energy storage capacity. Electrochemical energy storage devices consist of electrode materials, electrolyte, and current collector, which is critical to the overall electrochemical performance. There is an urgent need to solve the safety problems of lithium ion battery (L...

Ethylene is one of the most important building blocks in the petrochemical industry and a natural plant hormone widely used in agriculture. Metabolic Engineering Group has realized continuous and stable ethylene production by using model cyanobacterium Synechocystis sp. PCC6803. Ethylene is one of the most important building blocks in the petrochemical industry and a natural plant hormone widely used in agriculture. Traditional ethylene production mainly relies on the steam cracking of petroleum-based feedstock. Consideri...

polyurethane hydrogels with strong mechanical strength and high water-absorption ratio may find their applications in soil-water conservation and desertification combating. By carefully tuning the structure of polyols and the density of the cross-linkable functional groups, professor WAN Xiaobo and his colleagues found a way to unify the high water-absorption ratio and high compressive strength in one material.
Polyurethanes that could form hydrogel when contacted with water are of great interests for their plausible applications. It could be used as high-performance industrial materials and materials for medical treatment.
Figure 1. Polyurethane syn...
