Olefin copolymerization by FI catalysts with high incorporation ability
Recently, we successfully developed a new series of FI catalysts that exhibit high incorporation ability. These FI catalysts show high catalytic performance in ethylene/alpha-olefin, ethylene/cyclic olefin, and ethylene/polar monomer copolymerizations.

Novel superconducting structures of BH2 under high pressure
The crystal structures of boron hydrides in a pressure range of 50–400 GPa were studied using the genetic algorithm (GA) method combined with first-principles density functional theory calculations. BH4 and BH5 are predicted to be thermodynamically unstable. Two new BH2 structures with Cmcm and C2/c space group symmetries, respectively, were predicted, in which the B atoms tend to form twodimen...

Stability and superconducting properties of GaH5 at high pressure
Using genetic algorithm (GA) method combined with first-principles calculations, the structures, dynamical and thermodynamic stabilities of GaH5 were studied. The calculated results suggested that at the pressure range 150–400 GPa, the P21/m phase of GaH5 is the most favorable phase and dynamically stable, but thermodynamically it is unstable and can decompose into GaH3 and H2. The supercond...

High H2 Adsorption by Coordination-Framework Materials
A series of coordination frameworks with different pore sizes (see structure of one; Cu blue, C gray, H white, O red) are prepared from CuII ions and carboxylate ligands of various lengths. Comparison of their sorption properties reveals that smaller pores allow higher densities of adsorbed H2, whereas larger pores allow higher maximum H2 storage capacities.

Crosslinked waterborne polyurethane with high waterproof performance
A study on the cross-linking of fluorinated acrylate and siloxane waterborne polyurethanes was carried out in order to produce a material with improved waterproof property. Trimethylolpropane-tris-(β-N-aziridinyl) propionate was employed as a simple, fast curing and low cost crosslinking agent. It follows that the acquired polyurethane film had the lowest water absorption and highest water contac...
