How to improve the stability and processability of organic-inorganic hybrid perovskite quantum dots(OHPQD)is an important topic in recent research.In this work,the stability and machinability of OHPQD were improved by blending with PU elastomer.The CsPbBr_(3)-PU composites can be achieved easily by pouring molding process with rather excellent humidity and thermal stability.The tensile strength of 14​MPa and elongation of 580%at break of PU/CsPbBr_(3) elastomer composites with self-repair properties were obtained,which was attributed to the introduction of disulfide bonds.It lays a foundation for the application of OHPQD. 展开更多

Pressurized Fluidized Bed Combustion(PFBC) is recognized as an advanced coal-fired technology which can improve efficiency in combined cycle scheme and reduce environmental pollution. Progressive status on PFBC-CC in China is presented in this paper. Test results on a 1 MWt bench scale experimental PFBC facility is reviewed briefly. Based on retrofitting of an old steam power plant located at Jiawang,a project to construct a PFBC-CC pilot plant is under way. Designed capacity of the pilot plant is about 15 MWe, 3 MWe from gas cycle and 12 MWe from steam cycle. The system configuration, main design parameters, estimated technical performance as well as construction schedule of the pilot plant are described. The bright future for PFBC-CC in China is also indicated. 展开更多

The synergistic effect of phenolic and thio antioxidants on the stabilization of acrylonitrile-butadienestyrene(ABS)graft copolymers has been studied.Three commercial antioxidants Irganox245,Irganox1076 and dilauryl thiodipropionate(DLTP)were selected.Formulations based on hindered phenols and secondary antioxidant DLTP were prepared.Stabilization was monitored in terms of changes in the functional groups(oxidation products),tensile properties and yellowness index.Differential scanning calorimetry(DSC)and thermogravimetry(TG)were also used to assess the stability.The results indicated that the combination of Irganox245 and DLTP showed much better stabilization effect than the individual components due to the strong synergistic effect.Only weak synergism could be observed in the formulation that contained Irganox1076 and DLTP.Irganox1076 and Irgnox1076/DLTP exhibited similar behaviors between antioxidants with the highest and lowest efficiencies. 展开更多
