TiO2 nanoparticle (NP)/ITO nanowire (NW) nanocomposites for use as photoelectrode materials were fabricated to improve the charge collection efficiency in solid state dye sensitized solar cells (ss-DSSCs). The average current density for ss-DSSCs containing TiO2 NP/ITO NW arrays was 7.2 mA cm(-2) that was 98% higher t…
Few-layer graphene/TiO2 nanocrystal composites are successfully in situ synthesized at a low temperature of 400 °C using C28H16Br2 as the precursor. Raman mapping images show that the TiO2 nanocrystals are very uniformly dispersed in the composite films, and the in situ coating during the thermal decomposition process…
An organic salt based on double 1,3,4-oxadiazole derivatives as fluorophores and BAPTA as a receptor has been designed for detection of Cd(2+). The fluorescent probe exhibits high selectivity for Cd(2+) and a low detection limit of 20 nM in aqueous solution, making it useful for Cd(2+) imaging in living MCF-7 cells.
We have prepared an yttrium modified Pt(111) single crystal under ultra-high vacuum conditions, simulating a bulk alloy. A Pt overlayer is formed upon annealing the crystal above 800 K. The annealed structure binds CO weaker than Pt(111), with a pronounced peak at 295 K in the temperature programmed desorption of CO.…
Composites strengthened with nanocellulose have been developed with the aim of improving mechanical, barrier, and thermal properties of materials. This improvement is primarily due to the nanometric size and the high crystallinity of the incorporated cellulose. Cassava starch films plasticized with glycerol and incorp…
作为燃料来源用土壤有机物影响单个房间的微生物引起的燃料房间(MFC ) 的发电的因素有有限信息。我们检验了土壤和水深度的效果，并且有阳极的土壤 MFC 的表演上的温度在覆盖的水里在充满的土壤和阴极正在被嵌入。结果证明有覆盖的深土壤和 3 厘米浇的 5 厘米的 MFC 展出了 562 mV 和 0.72 mW m2 的功率密度的最高开的电路电压。欧姆的电阻与更多的土壤和水增加了。当阳极的与更多的水增加了时，阴极的极化电阻与更多的土壤增加了。在 30 d 操作期间，房间电压断然与温度相关并且与 500 外部负担到达了 162 mV 的最大值。在操作以后，从土壤和阳极的细菌的 16S rRNA 基因被定序。在土壤的细菌比那些遵守细菌主要…
Photoelectric properties of noncentrosymmetric, similarly oriented metallic nanoparticles embedded in a homogeneous semiconductor matrix are theoretically studied. Because of the asymmetric shape of the nanoparticle boundary, photoelectron emission acquires a preferred direction, resulting in a photocurrent flow in th…
Twenty years ago, dissolution media were used almost exclusively for quality control purposes in the pharmaceutical industry. The most common dissolution tests were for oral dosage forms, and these were approached according to the release mechanism— immediate release (IR), enteric-coated (EC) tablets, and controlled-r…
This study reports the effect of water on the formation of a zinc oxide (ZnO) thin film and the performance of ZnO thin film transistors (TFTs).
A family of novel sulfonate based homopolymers has been prepared by partially replacing sodium cations with different types of ionic liquid ammonium counter-cations, leading to an increased degree of decoupling of the conductivity from the glass transition of the ionomers.
The accumulation of dissociated charge carriers plays an important role in reducing the loss occurring in organic solar cells. We find from light-assisted capacitance measurements that the charge accumulation inevitably occurred at the electrode and photovoltaic layer interface for bulk-heterojunction ITO/PEDOT:PSS/P3…
Intumescent coatings (also called reactive coatings) are widely used to protect structural steel from fire. These thin coatings swell on heating to form a highly insulating char, protecting steel members and preventing them from reaching critical temperatures that could cause them to fail. As is the case for most stru…
Principal features of crystal packing for the series of complexes were revealed by computational approach.
Pure CZTS thin film is formed directly at a temperature of 250 °C, the lowest temperature of any current fabrication system, on both flexible stainless steel and rigid FTO substrates.
Review of theoretical and experimental research relating to the formation and distribution of post-blast explosive residues.
Particles with sophisticated surface patterns have many potential applications ranging from information coding to catalysis and optics. However controlled patterning of particles often requires rather complicated lithographic or template based approaches. Here we report a straightforward chemical synthesis of complex…
The syntheses of several 3,6-dihalopyromellitic diimides have been achieved. Two-point intermolecular halogen–oxygen interactions—reminiscent of carboxylic acid dimers—are observed in the solid-state superstructures of (i) these molecules and (ii) their charge-transfer complexes with electron-rich naphthalenes.
In a fire, normally non-hazardous thermoplastic materials can produce lethal concentrations of toxic effluents in the smoke. The toxic product yields of the asphyxiants carbon monoxide (CO) and hydrogen cyanide (HCN) from developed fires are typically 10 times greater than those generated in small-scale laboratory fir…
The reaction of N-(2-pyridylmethyl)iminodiethanol (H2pmide) and Fe(NO3)3·9H2O in MeOH led to the formation of a dimeric iron(III) complex, [(Hpmide)Fe(NO3)]2(NO3)2·2CH3OH (1). Its anion-exchanged form, [(pmide)Fe(N3)]2 (2), was prepared by the reaction of 1and NaN3 in MeOH, during which the Hpmide ligand of 1 was also…
The purpose of the present study was to achieve laser-microtextured Si structures, the material used as silicon wafers, with a thickness of 330 mu m for a fast laser texturing technique, in order to produce micro-/nanosurface textures by means of a UV femtosecond laser. A textured silicon surface was prepared that has…
