Chiral N, N''-Dioxide-Sc( OTf) 3 Complexes Catalyzed Asymmetric Reactions
The development of high efficient and environmental friendly catalysts is an important effort in the study of asymmetric catalysis to construct potentially useful chiral molecules. Scandium( III ) ion is the most Lewis acidic as the smallest rare-earth-metal cation. The electronic properties of scandium cation offer its remarkably excellent outcomes m many organic reactions compared with traditi...

Preparation and characterization of carbon dioxide and ph sensitive copolymers based on dextran
As we all know, lower pH and higher redox are the iconic characteristics of cancer sites[1], which is also thetheoretical basis of controlled release of the anticancer drug. Therein, the preparation of drug carriers which hav...

Influence of Water and Supercritical Carbon Dioxide on the Rheological Behaviour of Polycondensate Melts
Extrusion and synthesis processes of melt polycondensates require particular conditions because of the high melt temperature range (150°C to 350°C). Capillary rheometry or slit rheometry during extrusion process were the most appropriate ...

Preparation of inverse opal cerium dioxide for optical properties research
Inverse opal cerium dioxide (CeO2) is prepared with polystyrene (PS) microsphere opal template and sol–gel method, and characterized in detail. The opal template and inverse opal CeO2 show different colors in the light of halogen tungsten lamp and have a long-range ordered three dimensional periodic structure. Comparing with the opal template, the size of the inverse opal CeO2 shows shrinkage. Th...
