Novel self-assembled natural graphite composites (SANGs) were prepared by the granulation of natural graphite and acrylonitrile/styrene copolymer (SAN) particles by a spray-drying and subsequent pyrolysis procedure.
Although extremely sensitive, electrical measurements are essentially unable to discriminate complex chemical events involving individual nanoparticles. The coupling of electrochemistry to dark field imaging and spectroscopy allows the triggering of the electrodissolution of an ensemble of Ag nanoparticles (by electro…
The degradation rate, hydrophilicity, and mechanical properties of PLLA/PLGA/HA scaffolds can be tuned by adjusting the composition. Such tailor-made scaffolds are hopeful to address the specific requirements of the regenerated tissue.
This manuscript describes the highly efficient OLEDs with low efficiency roll-off based on iridium( iii ) complexes bearing oxadiazol-substituted amide ligands.
In this study, epoxy (EP) composites filled with different contents of polyvinylidene fluoride (PVDF) and carbon nanotubes (CNTs) were fabricated by the solvent evaporation and curing method.
Eight Zn(II) coordination polymers with 5-R-1,3-benzenedicarboxylate (R = H, Br) ligands and bis-imidazolyl ligands, {[Zn(1,3-BDC)(abimb)]·H2O}n (1), {[Zn(5-Br-1,3-BDC)(abimb)]2·0.5H2O}n (2), [Zn(1,3-BDC)(nbimb)]n (3), [Zn(5-Br-1,3-BDC)(nbimb)]n (4), {[Zn(1,3-BDC)(bimpa)]·2H2O}n (5), {[Zn(5-Br-1,3-BDC)(bimpa)]·2H2O}n…
Although Cu 2 S-containing chalcogenide solar cells are appealing and cost-effective for photovoltaics (PVs), these materials suffer from rapid performance degradation as a result of the diffusion of copper ions into the CdS layer.
We report here a comprehensive understanding of the first C-C coupling during the induction period of the methanol-to-olefin process using density functional theory with the HSE06 hybrid functional. We illustrate the possible routes of formation for the active carbenium ion (CH3OCH2(+)), which has been identified to p…
A new linear polymer containing the dialkylaniline-substituted electron-rich alkynes in the side chains was designed and synthesized by copper-catalyzed azide–alkyne cycloaddition (CuAAC).
New bis-2-azapropenylium ions are obtained by oxidation of guanidino-substituted aromatic compounds.
Surfaces modified with a functional molecular monolayer are essential for the fabrication of nano-scale electronics or machines with novel physical, chemical, and/or biological properties. Theoretical simulation based on advanced quantum chemical and classical models is at present a necessary tool in the development,…
Most studies on hydrogel swelling instability have been focused on a constrained boundary condition. In this paper, we studied the mechanical instability of a piece of disc-shaped hydrogel during free swelling. The fast swelling of the gel induces two swelling mismatches; a surface-inner layer mismatch and an annulus-…
We present, for the first time, portable defocusing micro-Spatially Offset Raman Spectroscopy (micro-SORS). Micro-SORS is a concept permitting the analysis of thin, highly turbid stratified layers beyond the reach of conventional Raman microscopy. The technique is applicable to the analysis of painted layers in cultur…
This study aims at clarifying the effects of delamination on fretting wear behaviors of plasma-sprayed hydroxyapatite coating. Plasma-sprayed hydroxyapatite (HAp) coating has been widely used as a bond between human bone with artificial metallic implants in order to smoothly transmit loads by gaits. However, HAp coati…
Electrodeposition of nanocrystalline zinc coating is greatly significant in improving the mechanism, wear and corrosion properties of conventional coarse-grained zinc coating and its formation is usually by the synergetic effect of two or more additives on electrodeposition reaction. However, the multicomponent additi…
In this study, we investigated the color, gloss and surface roughness of bamboo (Phyllostachys bambusoides) and Scots pine (Pinus sylvestris) samples impregnated with boron and copper based preservatives during accelerated weathering from 168 h to 672 h. Tanalith-E, ACQ, wolmanit-CB were used as copper-based chemicals…
The photocatalytic activity of 4-CP degradation is apparently enhanced by doping Zr and modifying Pd in TiO 2 (TiO 2 –Zr–Pd) under visible light irradiation.
A novel preheating method was used in preparing perovskite films ,which results in synchronized improvements in photovoltage ( V oc ), photocurrent ( J sc ) and fill factor (FF) lead to ~25% enhanced power conversion efficiency (PCE).
In aqueous DMSO solution, ratiometric fluorescent hydrazine probe COUMA2 undergoes hydrazinolysis affording deacetylation products displaying dual emissive peaks at 500 and 655 nm.
Manganese cobalt oxide (MnCo 2 O 4 ) nanosheets were grown on Nickel (Ni) foam by a simple electrodeposition method and its glucose sensing and field emission properties have been investigated.
