Using ZnO seed layers, an efficient approach for enhancing the heterointerface quality of electrodeposited ZnO–Cu2O solar cells is devised. We introduce a sputtered ZnO seed layer followed by the sequential electrodeposition of ZnO and Cu2O films. The seed layer is employed to control the growth and crystallinity and…
In this paper, on the basis of a simple side-by-side co-electrospray procedure with a subsequent non-equilibrium calcination process, we have for the first time developed an asymmetric shrinkage approach for the fabrication of magnetic γ-Fe(2)O(3)/TiO(2) Janus hollow bowls (JHBs) by constructing a precursor solution p…
A novel method for the topological description of high nuclearity coordination clusters (CCs) was improved and applied to all compounds containing only manganese as a metal center, the data on which are collected in the CCDC (CCDC 5.33 Nov. 2011). Using the TOPOS program package that supports this method, we identifie…
We reported the fabrication of a highly flexible, sensitive, and excellent reproducible photo-detector based on flexible nanoparticle-assembled ZnO cloth, which was synthesized via a carbon cloth templated hydrothermal method. The conductance of the device increased more than 600 times after UV irradiation. The respon…
An efficient and general strategy for the dispersion of multi-walled carbon nanotubes in water and organic media was developed for the first time via the combination of mussel-inspired chemistry and the Michael addition reaction.
Poly(3,4-ethylenedioxythiophene) doped with poly(4-styrenesulfonate) (PEDOT/PSS) was synthesized by oxidative polymerization and pH dependence of structure and electrical conductivity of the cast films were investigated by means of UV-vis-NIR, XRD, AFM analyses, and four-point technique. It was found that the neutrali…
The electrochemical corrosion behavior of magnetron sputtered nanocrystalline (NC) 304 stainless steel (ss) thin film as well as that of the conventional rolled coarse crystalline (CC) 304ss has been studied in 0.05 M H 2 SO 4 + 0.2 M NaCl solution using electrochemical and imaging techniques. The experimental results…
A novel greener method to impregnate silver nanoparticles (AgNPs) into microcrystalline cellulose (MCC) by curry leaf (Murraya koenigii) extract mediated biological process is presented. The active reduction of silver ions by curry leaf extract was explored for the in situ impregnation AgNPs into MCC. Transmission ele…
A series of zinc silylamido complexes bearing claw-type multidentate aminophenolate ligands, [LZnN(SiMe(3))(2)] (L = -OAr(1)-CH(2)N[(CH(2))(n)NR(2)]CH(2)Ar(2), n = 2 or 3; R = Me or Et (1a-3a, 5a, 7a and 8a); L = -OC(6)H(2)-4,6-(t)Bu(2)-2-CH(2)N[(CH(2))(2)OMe](2) (9a)), have been synthesized via the reaction of Zn[N(S…
Highly transparent and conductive Indium-doped ZnO (ZnO:In) thin films with different In content were deposited on quartz glass slides by RF magnetron sputtering at room temperature. The thickness and the optical constants of the films were obtained by the Swanepoel method, and the effects of In concentration on the o…
On the basis of density functional theory calculations, we show that edge-decorated graphene nanoribbons (GNRs) by scandium can bind multiple hydrogen molecules in a quasi-molecular fashion. The average adsorption energy of H(2) on Sc ranges from 0.17 to 0.23 eV, ideally suited to hydrogen storage. For the narrowest G…
A new polar material containing two types of stereoactive lone-pairs has been synthesized. The unique parallel alignment of the stereoactive lone-pairs on Pb(2+) cations and the synergistic effect of two types of stereoactive lone-pairs on I(5+) and Pb(2+) cations make it exhibit a very large second-harmonic generatio…
In this paper, we report a facile hydrothermal method for the preparation of spherical ZnS based nanocrystals (flower-like architectures), using Zn(acac)2 and thioacetamide (TAA) as the Zn2+ and sulfur sources and thioglycolic acid (TGA) as the capping agent. The influence of temperature and polyethylene glycol (PEG),…
Two organic sensitisers 4-biphenylcarboxylate (BPC) and terephthalate (TA) were intercalated into the gallery of layered europium hydroxide (LEuH). PL spectra tests indicated that BPC markedly enhanced the red luminescence of Eu(3+) due to efficient energy transfer between BPC and Eu(3+), forming a contrast to interca…
Carbon nanotube and metal oxide/hydroxide hybrids have attracted much interest as electrode materials for electrochemical supercapacitors because of their dual storage mechanism. They can complement or replace batteries in electrical energy storage and harvesting applications, where high power delivery or uptake is ne…
Abstract. Graphene-enabled wireless communications constitute a novel paradigm which has been proposed to implement wireless communications among nanosystems. Indeed, graphene-based plasmonic nano-antennas, or graphennas, just a few micrometers in size have been predicted to radiate electromagnetic waves at the terahe…
The fluorescence of tetra(4-pyridylphenyl)ethylene (1) can be switched on significantly by the synergistic interactions of Hg(2+) and HSO(4)(-) based on a new aggregation mechanism for tetraphenylethylene molecules.
Presented in this article is the synthesis of a new class of block copolymer, poly(ethylene oxide)-block-poly(tert-butyl acrylate-stat-acrylic acid) [PEO-b-P(AA-stat-tBA)], which can self-assemble into polymer vesicles with tuneable sizes at various conditions. The biocompatible and hydrophilic PEO chains form the ves…
Supramolecular π-gels were formed in a mixture of aliphatic alcohols and water for a series of chromophoric phenylenedivinylene bis-N-alkyl pyridinium salts (PPV) appended with terminal aliphatic hydrocarbon chains of different lengths. Gelation could be controlled either by altering the ratio of various alcohol–water…
For the first time, two bipolar AIE-active luminogens (Oxa-pTPE and Oxa-mTPE) constructed from tetraphenylethene and oxadiazole were utilized as fluorescence host materials in sky-blue doped OLEDs and exhibited high efficiencies with L(max), η(C,max), η(P,max) and η(ext,max) of 10,070 cd m(-2), 9.79 cd A(-1), 9.92 Im…
