关键字：poly(ε-caprolactone), porous microspheres, paraffin, microsphere/hydrogel composite, in vitro.
Openporous microspheres could provide large specific surface areas for cell adhesion and sustained cell growth. Introduction of cell-loaded microspheres into hydrogel might provide a cell-affinitive environment to maintain cell viabilities and improve cell growth in hydrogel system. Here, the open porous poly(ε-caprolactone) (PCL) microspheres were fabricated via the combinated phase separ...

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...

【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...

[Composites Science and Technology]Fabrication and investigation on the Fe3O4/thermally annealed graphene aerogel/epoxy electromagnetic interference shielding nanocomposites
Ethylenediamine functionalized Fe3O4 (NH2-Fe3O4) nanoparticles and graphene oxide (GO) were compounded firstly, followed by the addition of l-ascorbic acid, to obtain the Fe3O4/thermally annealed graphene aerogel (Fe3O4/TAGA) by thermal annealing method. And the Fe3O4/TAGA/epoxy nanocomposites were then fabricated via template-casting method. When the mass ratio of GO to NH2-Fe3O4 was 2:1 and th...

54. [Applied Surface Science] Mussel-inspired tough hydrogels with self-repairing and tissue adhesion
The mussel-inspired polymeric hydrogels have been attractively explored owing to their self-repairing or adhesive property when the catechol groups of dopamine could chelate metal ions. However, it was a chal- lenge for self-repairing hydrogels owning high mechanical properties. Herein, a synergistic strategy was proposed by combining catechol-Fe3+ complexes and hydrophobic association. The resu...
