The anhydrous calcium chloride absorbs the water contents in the airturns them into liquid water. The liquid water then becomes the electrolyte to initiate the electrochemical reaction of the metal-air fuel cell. The electricity generated from the fuel cell is used to power the ventilation fan inside a wardrobe cabinetcreates its circulation with outside atmosphere.

This invention provides a method for synthesis a catalyst for catalyzing hydrogenation of CO2 to methanol. The precipitation process was controlled at 70 oCaging for 1.5 hour. The CuO: ZnO: Al2O3 weight ratios are 7: 3: 1. The particle size of CuO is less than 5 nm. The reaction is carried at 50 bar250 oC, CO2/H2= 1/3. Adding hydrophobic fumed silica, water is expelled from catalyst surface,the reaction can shift to product side. Therefore the CO2 conversion can reach 90 thermodynamic equilibrium conversion, methanol selectivity is greater than 95.

"The team established material doping technology to greatly improve the piezoelectric properties of lead-free materials,successfully prepared MEMS lead-free triaxial piezoelectric accelerometers. The use of lead-free materials is the world＇s first development result. In addition, the team also integrated sensors, back-end circuitsuser interfaces, applied the acceleration gauge system to the safety monitoring of unmanned vehicles,successfully integrated the intelligent integrated sensingcontrol system required in the Internet of Things era."
