关键字：ATRP /PCL/PDEAEMA /pH sensitivity/ ROP/self-assembly
Four-arm star block polymers consisting of hydrophobic poly(ε-caprolactone) (PCL) block and hydrophilic poly(2-(diethylamino) ethyl methacrylate)) (PDEAEMA) block were successfully synthesized by ring opening polymerization (ROP) and atom transfer radical polymerization (ATRP). Chain lengths of PDEAEMA segments were varied to obtain a series of star copolymers with different hydrophilic/hy...

关键字：silver nanoparticles; star-shaped copolymers; poly(ε-caprolactone); coordination reduction; nanoreactors; catalytic activity.
Silver nanoparticles (Ag NPs) were prepared via in-situ reduction of silver nitrate (AgNO3) using polymeric micelles as nanoreactors without any additional reductant. The micelles were constructed from the amphiphilic star-shaped copolymer composed of poly(ε-caprolactone) (PCL) segment, 2-(Dimethylamino)ethyl methacrylate (DMAEMA or DMA) units and oligo(ethylene glycol)monomethyl ether met...

The Proper Generalized Decomposition: A Powerful Technique for High-Dimensional Problems Applied to Computational Rheology
Many problems in science and technology remain intractable in view of the so-called curse of dimensionality. Consider for example the quantum-mechanical description of a physical system made of N particles.

Effect of voltage on electrospinning oil sorptive fiber
关键字：Electrospun fiber, applied voltage, scaling law, average diameter, oil sorption rate
Electrospinning is a convenient method used in the preparation of ultrafine oil sorptive fibers based on ethylene-propylene-diene (EPDM). Electrospun fiber diameter, varying largely from micrometer to nanometer, mainly depends upon the applied&n...

【75 Journal of Applied Polymer Science】Poly-lysine conversion to nitrogen-containing porous carbon flakes: Potential application in supercapacitors
Poly-lysine conversion to nitrogen-containing porous carbon flakes: Potential application in supercapacitors
The derived lysine from biomass fermentation is a naturally abundant renewable resource. However, the small molecular size of lysine limits its processing and application. On the other side, carbonization of polylysine into high‐valued carbon materials is one of convenient options to...

【Applied Physics A】Efficient growth of millimeter-long few-walled carbon nanotube forests and their oil sorption
Millimeter-long few-walled carbon nanotube (FWNT) forests were grown by a water-assisted chemical vapor deposition method. In only 10 min, the forests grew to over 1.2 mm in height, with a growth yield around 2.76±0.30 mg/cm2. Transmission electron microscopy observation and Raman analysis showed high crystallinity of the nanotubes. A carbon purity better than 98.8 wt% was further determined by...

【Applied Surface Science】Investigation on surface layer characteristics of shot peened graphene reinforced Al composite by X-ray diffraction method
Graphene reinforced Al composite with high mechanical property was successfully reported. However, there are quite limited studies about shot peening effect on this new type material. Here, 1.0?wt% graphene reinforced Al composite was produced by powder metallurgy and treated by shot peening. The surface layer characteristics of shot peened composite was investigated by X-ray diffraction line pr...

【Applied Surface Science】Ultrathin Mo/MoN Bilayer Nanostructure For Diffusion Barrier Application Of Advanced Cu Metallization
Ultrathin Mo (5 nm)/MoN (5 nm) bilayer nanostructure has been studied as a diffusion barrier for Cu metallization. The Mo/MoN bilayer was prepared by magnetron sputtering and the thermal stability of this barrier is investigated after annealing the Cu/barrier/Si film stack at different temperatures in vacuum for 10 min. The failure of barrier structure is indicated by the abrupt increase in shee...

【40 Applied Catalysis B: Environmental】 Converting mixed plastics into mesoporous hollow carbon spheres with controllable diameter
Upcycling waste plastics into high value-added carbon nanomaterials has been a hot topic due to ever-increasing generation of waste plastics, however, little attention has been paid to valuable hollow carbon spheres (HCSs). Herein, uniform mesoporous HCSs with controllable diameter and high surface area were efficiently prepared through the carbonization of mixed plastics consisting of polypropyle...

【13 Journal of Applied Polymer Science】 In situ chemically crosslinked chitosan membrane by adipic acid
Adipic acid, which is nontoxic, was used to dissolve chitosan. The chitosan/adipic acid solution was used to prepare chitosan membrane. After being heated at 80-100 °C, the membrane was in situ chemically crosslinked by adipic acid, as verified by Fourier transform infrared and wide‐angle X‐ray diffractometer analysis. The crosslinked membrane did not collapse even without treatment in alkaline...
