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…
<abstract language="eng">In this study, novel Chitosan/PVA based films were chemically crosslinked by glutaraldehyde, under pH=(4,00 ±0,05), in order to achieve structures tailored for wound tissue engineering applications. Both precursors and developed films were characterized by FTIR, SEM and XRD in order to determi…
The purpose of the study was to develop the liposomal formulations of TFu for oral and intravenous (i.v.) administration, clarify the biodistribution characteristics and in vivo pharmacokinetic behaviors of TFu-loaded liposomes. Four TFu-loaded liposomes of different sizes were prepared and characterized. The pharmaco…
Density Functional Theory calculations are reported on cage structured BN, AlN, GaN and InN sub- and low nanosize stoichiometric clusters, including two octahedral families of T(d) and T(h) symmetry. The structures and energetics are determined, and we observe that BN clusters in particular show high stability with re…
High internal phase emulsions (HIPEs) incorporating styrene, 4-vinylbenzyl chloride, divinylbenzene and ethylhexyl acrylate were applied to prepare reactive, cross-linked porous membranes with open cellular architecture and thicknesses between 30 and 500 microm.
The influence of intermetallic particles (IMPs) on the localized corrosion behavior of an EN AW-3003 alloy was investigated in situ by conventional electrochemical measurements and high-resolution local probing techniques in chloride solutions with and without acetic acid. The open-circuit potential (OCP) fluctuations…
Encapsulation of magnetite (IOPs) in gelatin nanoparticles has been carried out by in situ precipitation of the particles in presence of gelatin, followed by desolvation and cross-linking of the composite nanoparticles. The aim of the study was to investigate the effect of various formulation parameters (viz; desolvat…
An organometallic Au(III) complex of N-confused tetraphenylporphyrin has been synthesized and its electrochemical and photophysical properties investigated; unique emission is observed in solution at ambient temperature.
A large optical birefringence of oriented Ag nanoellipsoids embedded in silica was measured using an ellipsometric technique. The two main surface plasmon resonances associated with the axes of the ellipsoid were tuned, allowing us to quantify the light transmission through the samples when placed and rotated between…
The gasification process of phosphorus from municipal sewage sludge during carbothermic reduction process was investigated using a quadrupole mass spectrometer gas analysis and thermo-gravimetric analysis. Two types of sludge, with high and low Fe2O3 content, were used to evaluate the possible effect of Fe2O3 on the g…
The effects of manufactured carbon black (CB) nanoparticles on reproduction and early development of the marine brown algae Fucus serratus were studied. Results obtained indicated that effects of CB on sperm concentration and fertilization, body axis alignment, germination and rhizoid elongation were primarily physica…
