[2015][J. Phys. Chem. C, 2015, 119 (45), 25243–25251]End-Group Engineering of Low-Bandgap Compounds for High-Detectivity Solution-Processed Small-Molecule Photodetectors
Several π-conjugated compounds based on diketopyrrolopyrrole and trithiophene substituted with different end groups (alkyl, alkyloxy, and alkylthio) were designed and synthesized for investigation of the material properties and photodetector performance brought by subtle changes in the end groups. Among all, compound 4 with hexylthio groups exhibits the most red-shifted absorption, strongest mo...

233. Flexible Hybrid Membranes with Ni(OH)2 Nanoplatelets Vertically Grown on Electrospun Carbon Nanofibers for High-Performance Supercapacitors.
The practical applications of transition metal oxides and hydroxides for supercapacitors are restricted by their intrinsic poor conductivity, large volumetric expansion, and rapid capacitance fading upon cycling, which can be solved by optimizing these materials to nanostructures and confining them within conductive carbonaceous frameworks. In this work, flexible hybrid membranes with ultrathin Ni...

[RSC Advances] Close-packed assemblies of discrete tiny silver nanoparticles on triangular gold nanoplates as high performance SERS probe
Bimetallic nanocatalysts often display enhanced
physical and chemical properties compared to those of their monometallic
counterparts, herein, we introduce a simple method to fabricate an island like
array of tiny Ag nanoparticles bounded on triangular Au nanoplates as the
surface-enhanced Raman scattering (SERS) substrate. The surface morphology of
the synthesized nanoparticles was characterized ...

Preparation and characterization of double macromolecular network (DMMN) hydrogels based on hyaluronan and high molecular weight poly(ethylene glycol)
Abundant research efforts have been devoted to meet the demands for high-strength hydrogels in biomedical applications. Double-network (DN) hydrogels and homogeneous hydrogels are two typical samples. In this study, a novel ultra-strong and resilient double macromolecular network (DMMN) hydrogel system has been developed via a two-step sequential cross-linking process using hyaluronan (HA) and hig...

Catechol-functionalized microporous organic polymer as supported media for Pd nanoparticles and its high catalytic activity
We report a new hydroxyl functionalized microporous organic polymer (MOPOH) based on the polymerization of catechol with terephthalaldehyde using phenolic resin-inspired chemistry. This catechol-decorated material, with surface area of 874 m2 g?1 and micro, mesopores, facilitates the immobilization and dispersion of Pd nanoparticles (NPs) on the polymer matrix. The surface area of t...

Assembly of an unbalanced charged polyampholyte onto Nafion to produce high-performance composite membranes
A novel SPES-NH2–GA-Nafions composite membrane with higher proton conductivity and lower methanol permeability was fabricated by covalent crosslinking layer-by-layer self-assembly of an unbalanced charged polyampholyte (SPES-NH2) and glutaraldehyde (GA) with controllable free sulfonic acid content.

Improvement of the thermal and thermo-oxidative stability of high-density polyethylene by free radical trapping of rare earth compound
A kind of rare earth compound, ytterbium trifluoromethanesulfonate (Yb(OTf)3), was introduced into high-density polyethylene (HDPE) by melt compounding to investigate the effect of Yb(OTf)3 on the thermal and thermo-oxidative stability of HDPE. The results of thermogravimetric (TG) and differential scanning calorimetry (DSC) showed that the addition of Yb(OTf)3 made the thermal degradation tempera...
