Perovskite corrosion by TBP was proved, and montmorillonite (MMT) was used as dual-functional buffer layer to prevent corrosion and retard electron recombination.
Novel N, S co-doped graphene (NSG) was prepared by annealing graphene oxide with thiourea as the single N and S precursor. The NSG electrodes, as efficient metal-free electrocatalysts, show a direct four-electron reaction pathway, high onset potential, high current density and high stability for the oxygen reduction r…
Uniform carbon fibers evolved from bamboo chopsticks garbage are achieved by a facile hydrothermal method, exhibiting competitive electrochemical behavior with commercial graphite, or pretty high anodic performance after being optimized.
A novel class of tetraphenylethene (TPE) derivatives TPEM and TPEBM containing dicyanovinyl groups were synthesized, possessing remarkable dual properties of solvatochromism and aggregation-induced emission (AIE). The combination of the electron-donating TPE and the electron-accepting dicyanovinyl group endow both com…
Thin film solar cells with a Cu(In,Ga)Se2 (CIGS) absorber layer achieved efficiencies above 20%. In order to achieve such high performance the absorber layer of the device has to be doped with alkaline material. One possibility to incorporate alkaline material is a post deposition treatment (PDT), where a thin layer o…
Supported ionic liquids (SILs), which refer to ionic liquids (ILs) immobilized on supports, are among the most important derivatives of ILs. The immobilization process of ILs can transfer their desired properties to substrates. Combination of the advantages of ILs with those of support materials will derive novel perf…
The influence of dispersant, pH and various additives on stability of ZnO suspension have been studied. Water and ethylene glycol were used as dispersants, sodium dodecyl sulfate (SDS), cetyltrimethylammonium bromide (CTAB) and sodium carboxymethyl cellulose (NaCMC) have been adsorbed on ZnO particles. Equilibrium in…
Wound closure represents a primary goal in the treatment of very deep and/or large wounds, for which the mortality rate is particularly high. However, the spontaneous healing of adult skin eventually results in the formation of epithelialized scar and scar contracture (repair), which might distort the tissues and caus…
In this work, metal–organic framework (MOF) UMCM-1 and amino functionalized MOF (i.e., UMCM-1-NH2) were synthesized and their performances as luminescent probes were investigated. It is found that both unmodified and amino functionalized MOFs exhibit a luminescence quenching effect on metal ions. In particular, the am…
Among porous solids, MOFs exhibit a wealth of water adsorption behaviors.
Au–TiO 2 –graphene photocatalysts display high visible-light hydrogen production activity due to the load of Au nanoparticles and introduction of graphene.
Yttrium iron garnet (YIG) films that are in the nanometer thickness range and show extremely low damping are reported. The films were deposited via sputtering at room temperature and were then annealed in O$_{2}$at high temperature. A 22-nm-thick YIG film showed a Gilbert damping constant$\alpha = (8.58\pm 0.21)\times…
We have developed a simple and efficient strategy to fabricate WS2 nanosheets with low toxicity and good water solubility via a liquid exfoliation method by using H2SO4 intercalation and ultrasonication. The as-prepared WS2 nanosheets were employed not only as an NIR absorbing agent for photothermal therapy (PTT) but…
The bismuth element synthesized by a facile chemical solution method exhibited an admirable and stable photocatalytic activity towards the removal of NO under 280 nm light irradiation due to the surface plasmon resonance mediated direct photocatalysis, and most strikingly, showed a catalytic "memory" capability follow…
The Purpose of this work is to study about the microstructures, mechanical properties and wear characteristics of as cast silicon carbide (SiC) reinforced aluminum matrix composites (AMCs). AMCs of varying SiC content (0, 5, 10 and 20 wt. %) were prepared by stir casting process. Microstructures, Vickers hardness, ten…
A two-step spin-coating process was used to synthesize perovskite films at ambient conditions. Combining a PEDOT:PSS hole-transport layer and a PC 71 BM acceptor, the device achieves a power conversion efficiency of 16.31% with a remarkably high V oc of 1.05 V and FF of 0.78.
An electrochemically active biofilm was utilized for modification of CeO 2 nanostructures.
In order to confirm reasons that deteriorate cathode performances, Ni-rich Li[Ni 0.7 Mn 0.3 ]O 2 is modified by lithium isopropoxide to artificially provide lithium excess environment by forming Li 2 O on the surface of active materials. X-ray diffraction patterns indicate that the lithium oxide coating does not affec…
This feature article focuses on tuning options of photoluminescence properties of lanthanide containing Metal-Organic Frameworks (MOFs) and Dense Frameworks by selection of an appropriate set of metal ions together with suitable ligands. In addition to lanthanide-only systems, frameworks with main group and transition…
Tailored fabrication of non-stoichiometric semiconductors has attracted considerable interest since the oxygen vacancy is the fundamental and intrinsic defect in reduced semiconductors and has critical impacts on their physicochemical properties such as tuning optical absorption, increasing conductivity, etc. Therefor…
