Simple chiral sulfinyl imine–thioether ligands for Pd-catalyzed allylic alkylation
A set of chiral sulfinyl imine–thioether ligands are prepared via dehydration condensation of substituted benzaldehyde and chiral sulfinamide. The activity of these ligands in Pd-catalyzed asymmetric allylic a...

Structure and properties of gel-spun ultra-high molecular weight polyethylene fibers with high gel solution concentration
The gel-spun ultra-high molecular weight polyethylene (UHMWPE) fibers were prepared at the industrial production line with different gel solution concentrations of 15 wt%, 18 wt% and 24 wt%. The difference in ...

The influence of chitin nanocrystals on structural evolution of ultra-high molecular weight polyethylene/chitin nanocrystal fibers in hot-drawing process
Ultra-high molecular weight polyethylene (UHMWPE)/chitin nanocrystal (CNC) fibers were prepared. Compared with the pure UHMWPE fibers, the ultimate tensile strength and Young’s modulus of UHMWPE/CNC fibers are...

Performance of PAHs emission from bituminous coal combustion
Carcinogenic and mutagenic polycyclic aromatic hydrocarbons (PAHs) generated in coal combustion have caused great environmental health concern. Seventeen PAHs (16 high priority PAHs recommended by USEPA plus B...
