Facilely constructing 3D Porous NiCo2S4 Nanonetworks for High-Performance Supercapacitors
Three-dimensional (3D) porous NiCO2S4 nanonetworks were fabricated on nickel foam (NF) through an anion exchange reaction between NiCo2O4 nanosheets (hydrothermally grown on NF) and Na2S, and showed a very high specific capacitance of 1501.2 F g(-1) at 1 A g(-1) (even 2.5 times higher than that of NiCo2O4 nanosheets) and robust cycling stability for supercapacitors.

Carbon Spheres with Hierarchical Micropore-Nanosheet networks for High Performance Supercapacitors
N-doped carbon spheres with hierarchical micropore-nanosheet networks (HPSCSs) were facilely fabricated by a one-step carbonization and activation process of N containing polymer spheres by KOH. With the synergy effect of the multiple structures, HPSCSs exhibit a very high specific capacitance of 407.9 F g(-1) at 1 mV s(-1) (1.2 times higher than that of porous carbon spheres) and a robust cycli...

Micromechanical analysis of molecular orientation in high-temperature creep of polycarbonate
The molecular orientation of bisphenol-A polycarbonate (PC) was determined by the in-situ wide-angle X-ray diffraction (WAXD) measurement during high-temperature creep. The resulting creep and WAXD data were used to analyze the coupled deformation of macro-continuum and micro-structure. A four elements viscoelastic modelwas introduced to fit the creep results and describe the time-dependent orie...

High Conductivity and Adhesion of Cu-Cr-Zr Alloy for TFT Gate Electrode
The characteristics of Cu alloy (0.3 wt. % Cr, 0.2 wt. % Zr) thin film deposited by direct current (DC) magnetron sputtering deposition were investigated. The conductivity and adhesion of the Cu-0.3%Cr-0.2%Zr films were optimized by increasing the sputter power to 150 W and reducing the sputter pressure to 2 mTorr. With an annealing process (at 300 ?C for 1 h in argon ambient atmosphere), the re...

2018-ACS AMI: Semi-Crystalline Hydrophobically Associated Hydrogels with Integrated High Performances
Hydrophobically associated hydrogels (HA gels) are one of most extensively investigated high strength hydrogels. Semi-crystalline HA gels, prepared by micellar copolymerization, show high strength and notable functionalities of self-healing and shape-memory. However, the hydrophobic comonomers in these semi-crystalline HA gels are usually limited to the long alkyl length monomers (18-alkyl(meth)ac...

Pickering High Internal Phase Emulsions Stabilized by Worm-Like Polymeric Nanoaggregates
This paper reports the first Pickering high internal phase emulsion (HIPE) system stabilized solely by worm-like nanoaggregates. The cross-linked worms were prepared from dispersion polymerization of benzyl methacrylate (BzMA),with poly(dimethylamino ethyl methacrylate) (PDMA) macro-CTA as the stabilizer and ethylene glycol dimethacrylate(EGDMA) as the cross-linker, through polymerization-i...

High-performance ester-crosslinked hollow fiber membranes for natural gas separations
A significantly improved defect-free ester-crosslinkable hollow fiber membrane was developed through simultaneous optimization of the spinning solution and dry-jet/wet-quench spinning process variables. The resultant ester-crosslinked hollow fibers show extremely high separation productivity and efficacy with CO2plasticization resistance under aggressive feed conditions. The CO2 permeance was impr...
