In this article, we focus on using the multiex- citon generation (MEG) effect of quantum dot (QD) to realize quantum cutting of high-energy photons which will give rise to a remarkable increase of total photon number. To avoid the complicated solving of Schrodinger equation, we take approximations and develop a method…
A novel long-circulating nano-delivery system was constructed using block copolymers of poly monomethoxy-(ethylene glycol)-poly(D,L-lactic- co-glycolic acid)-poly(3(S)-methyl-morpholine-2,5- dione) (PELMD) and poly-monomethoxy (ethylene glycol)-poly-(D,L-lactic-co-glycolic acid) (mPEG- PLGA). The two copolymers posses…
Well-dispersed BaSO4 nanoparticles were synthesized in the presence of sodium polyacrylate（PAAS） by a simple precipitation method,with BaCl2 and（NH4）2SO4 as reactants.The different roles performed by PAAS in the synthesis of BaSO4 nanoparticles were investigated using X-ray diffractometry,Fourier transform infrared sp…
A simple approach has been developed to functionalize various substrates, such as gold and polyvinylchloride, with dopamine methacrylamide—a molecule with adhesive properties that mimic those of mussels—to produce a versatile and general platform for subsequent surface modification. With active double bonds on the sur…

, 当液体层厚度 h 和温度差别 T 被改变时，常规摆动出现并且很快消失在开的表面上，它变化。与 T 的生长，可见摆动的主导的频率也将成长，但是在某些频率以内被发现。驱动力， buoyance 和 thermocapillarity，为这 phenomanon 负责，当 h 在 4.55.0mm 之间时，平衡点被认为存在。当 Bo 比 3.7 小时，表面摆动区域也被发现在狭窄的差距以内限制了。
ZnOeAl2O3eB2O3eSiO2(ZABS)glass powder was used as interlayer to join alumina ceramics.The effect of joining temperature on the microstructure and strength of joints was investigated.The results showed that the ZABS glass can react with alumina substrate to form a layer of ZnAl2O4at Al2O3/glass interface.Bending test e…
In order to find out the relationships of reconstituted tobacco's quality with its fiber distribution and surface microstructure, the reconstituted tobacco products of seven manufacturers at home and abroad were analyzed. Their surface microstructure was compared, and the property of fiber in their products was analyz…
