We present a facile, room temperature and “fully liquid” method to specifically produce either copper nanoparticles or thin conductive copper films on silicon substrates by using a dedicated reduction process of mesitylcopper by H2 or an aminoborane.
The anatomy and the physical, mechanical, acoustical and chemical properties of pernambuco wood ( Caesalpinia echinata Lam.) were investigated to determine factors that could explain the different quality of sticks used in bow manufacture. Eighteen sticks were classified into four classes (A to D with A being the best…
Fibrinogen (Fg) nanofibrils were prepared by the ethanol-induced self-assembly of Fg molecules, which can be used as fibrous scaffolds to organize gold nanoparticles (NPs).
Abstract First-principle pseudopotential plane wave calculations and the Nudged Elastic Band method based on density functional theory (DFT) have been used in this article to study the dissociation of molecular hydrogen on a Mg(0001) surface and the subsequent diffusion of atomic hydrogen into the magnesium substrate.…
The compressive stress-strain loops of several commercial polymers at strain rates of nearly 700/s are determined in the standard split Hopkinson pressure bar. Four different polymers or typical thermoplastics: ABS, PA-6, PA-66 and PC are tested at room temperature. Cylindrical specimens with a slenderness ratio (= he…
The bimetallic complex [CoNi(pmzt)4] (pmtz- = 5-(pyrimidyl)tetrazolate ligand) has been prepared by hydrothermal treatment of an equimolecular mixture of the mononuclear complexes[Co(pmtz)2(H2O)2] and [Ni(pmtz)2(H2O)2]. The structure of [CoNi(pmzt)4] consists of (4,4) square-grid-like sheets, in which Co(II) and Ni(II…
The effects of cerium content in the range of 0–0.022 wt%, on the microstructure, texture and magnetic properties of four non-oriented electrical steels have been studied. After final annealing, grain size increased with increasing cerium content and reached a maximum value in the steel with 0.011 wt% cerium. Furtherm…
Close-packed coupled multielectrode arrays simulating a planar electrode were used to monitor the anodic current evolution as a function of position during initiation and propagation of crevice corrosion of AISI 316 stainless steel (UNS S31600) and Ni–Cr–Mo alloy 625 (UNS N06625). Scaling laws vs and vs derived from p…
The design and synthesis of oligomeric ligands based on benzylic thioethers is presented together with their ability to enwrap and stabilize gold nanoparticles with diameters below 2 nm, which become--with increasing length of the oligomer--more monodisperse and stable.
In this study, an attempt has been made to predict the drape profile of woven fabrics using finite element analysis. The finite element method has been used in the prediction of structural instability and post buckling behaviour. The drape parameters like Drape coefficient, Drape distance ratio, Fold depth index, Ampl…
The hydroquinone family of photochromic Schiff bases has been studied by means of stationary and time-resolved spectroscopic absorption and emission techniques in the UV-Vis spectral range in the temporal range from 100 fs to 1 h. The studies have revealed that besides the ultrafast excited state intramolecular proton…
We report here an efficient single step combined sonochemical and solvothermal synthesis process to obtain bulk quantities of nanospherical particles of cubic Mn 2 O 3 and characterized its pseudocapacitive characteristics in relevance to electrochemical capacitors for the first time. It has been found that quantitati…
Abstract 2,2′‐[bis‐ N (4‐choloro benzaldimin)]‐1,1′‐dithio has been synthesized and its inhibiting action on the corrosion of mild steel in 0.5 M sulfuric acid was investigated by various corrosion monitoring techniques, such as weight loss and potentiodynamic polarization techniques. The experimental results suggest…
Membrane electrode assemblies (MEA) for fuel cells require optimization of their nanoscale organization to reach performance parameters, which include enhanced power density, increased catalyst utilization and reduced cost. We applied sprayed layer-by-layer assembly to produce a high activity MEA for H(2)/O(2) fuel ce…
A red-emitting phosphor has been synthesized and characterized optically for white light-emitting diodes (LEDs). Because the oxyborate group can contain high concentration without concentration quenching, is a suitable host material for red-emitting phosphor for near-ultraviolet (n-UV) LEDs. When was co-doped with , e…
A series of new phosphors of were synthesized by conventional solid-state reactions. The X-ray diffraction data indicate that a pure phase of can be successfully obtained. The photoluminescence (PL) spectra, quantum efficiency, and CIE coordinates of were investigated. The PL and PL excitation spectra indicate that th…
The photo-, thermo- and solvatochromic properties of 2,3-dihydro-1',3',3'-trimethyl-6-nitrospiro-[1-benzopyran-2,2'-1H-indole] (BSP-NO(2)) were studied in ILs containing the anion [NTf(2)](-) by UV-Vis absorption spectroscopy, ab initio molecular orbital theory and density functional theory (DFT) calculations. It was…
In this paper, we present an automatic method for hair segmentation. Our algorithm is divided into two steps. Firstly, we take information from frequential and color analysis in order to create binary masks as descriptor of the hair location. Secondly, we perform a 'matting treatment' which is a process to extract for…
Three series of Au(I)-imidazole complexes with stoichiometries of [Au(Cn-bim)Cl], [Au(Cn-im)Cl], and [Au(Cn-im)2][NO3] x 2H2O (Cn-bim = N-CnH2n+1 -substituted benzimidazole and Cn-im = N-CnH2n+1-substituted imidazole) together with the compound of [Au(C18-bim)2][NO3] are synthesiszed. Typical structures of each series…
It is now generally agreed that the hydration water and solvational properties play a crucial role in determining the dynamics and hence the functionality of proteins. We present molecular dynamics computer simulation studies on staphylococcal nuclease (SNase) at various temperatures and pressures as well as in differ…
