2018-Macromol Mater Eng: Nanoclay Reinforced Self-crosslinking Poly(N-hydroxyethyl acrylate) Hydrogels with Integrated High Performances
Despite recent significant progress in fabricating tough hydrogels, it is still a challenge to realize high strength, large stretchability, high toughness, rapid recoverability and good self-healing simultaneous in a single hydrogel. Herein, Laponite reinforced self-crosslinking poly(N-hydroxyethyl acrylamide) (PHEAA) hydrogels (i.e. PHEAA/Laponite NC gels) with dual&nbs...

2018-Polym Test:Fully physical double network hydrogels with high strength, rapid self-recovery and self-healing performances
Double network hydrogels (DN gels) are one of most extensively investigated high strength hydrogels. However, conventional DN gels are fully chemically cross-linked, which often suffer from severe softening phenomenon and are lack of self-healing properties. In the present work, fully physically cross-linked Agar/PAAm DN gels, consisting of physical agar gel as the first network and physical polya...

High-efficiency encapsulation of Pt nanoparticles into the channel of carbon nanotubes as an enhanced electrocatalyst for methanol oxidation
Pt-based nanostructures serving as anode catalysts for the methanol oxidation reaction (MOR) have been widely studied for many years. Nevertheless, challenging issues such as poor reaction kinetics and the short-term stability of the MOR are the main drawbacks of such catalysts and limit their applications. Herein, we have developed a facile approach to encapsulate Pt nanoparticles (NPs) inside ...

Nitrogen-Doped Hierarchical Porous Carbon Nanowhisker Ensembles on Carbon Nanofiber for High-Performance Supercapacitors
Controlled synthesis of carbon nanomaterials with particular shape, composition, architecture, and doping is very important, yet still a great challenge, forenhancing supercapacitor performance with high energy and power densities and long lifetime. Herein, we demonstrate an interesting process combining surfactantless and templateless wet chemical and post-high-temperature carbonization strateg...

Rapid Preparation of Crosslinked N-doped Graphene by Burning Method for High-Performance Electrochemical Capacitors
We demonstrated here the crosslinked N-doped graphene (NG) can be rapidly prepared through a onestep burning process of graphene oxide. The doping process completed within 3 minutes and the N content in the obtained NG reached to 5.6%. The obtained crosslinked NG shows mesoporous structure with relatively high specific area, large pore volume and various N types. As a supercapacitor, the resulta...

Preparation of Ultra High Molecular Weight Polyethylene with MgCl2/TiCl4 Catalysts: Effect of Temperature and Pressure
The polymerization of ethylene (E) was carried out using a MgCl2-supported TiCl4 catalyst in conjunction with triethylaluminium as a cocatalyst. The effects of the polymerization temperature (Tp) and E pressure (PE) on E polymerization were studied. The maximum catalyst activity was obtained at 40 oC. The melting temperature (Tm) and crystallinity (Xc) were less affected by the Tp. The molecular...

Current rectifying and resistive switching in high density BiFeO3 nanocapacitor arrays on Nb-SrTiO3 substrates
Ultrahigh density well-registered oxide nanocapacitors are very essential for large scale integrated microelectronic devices. We report the fabrication of well-ordered multiferroic BiFeO3 nanocapacitor arrays by a combination of pulsed laser deposition (PLD) method and anodic aluminum oxide (AAO) template method. The capacitor cells consist of BiFeO3/SrRuO3 (BFO/SRO) heterostructural nanodots on c...

High-density ordered Ag@Al2O3 nanobowl arrays in applications of surface-enhanced Raman spectroscopy
In this paper, we demonstrate a high-performance surface-enhanced Raman scattering (SERS) substrate based on high-density ordered Ag@Al2O3 nanobowl arrays. By ion beam etching (IBE) the anodized aluminum oxide (AAO) and subsequent Ag coating, ordered Ag@Al2O3 nanobowl arrays were created on the Si substrate. Unlike the ''hot spots'' generated between adjacent metallic nanostructures, the Ag@Al2O3 ...
