Based on quantum chemistry calculations combined with the Marcus-Hush electron transfer theory, we investigated the charge-transport properties of oligothiophenes (nTs) and oligopyrroles (nPs) (n=6, 7, 8) as potential p- or n-type organic semiconductor materials. The results of our calculations indicate that 1) the nP…
Traditionally, samples are collected on-site (i.e., in the field) and are shipped to a lab for chemical analysis. An alternative is offered by using portable chemical analysis instruments that can be used on-site (i.e., in the field). Many analytical measurements by optical emission spectrometry require use of light-s…
Boron-doped zinc oxide (BZO) thin films have been fabricated by spray pyrolysis on a glass substrate. The morphology and electrical properties of the thin films were investigated. X-ray diffraction (XRD) and scanning electron microscopy (SEM) analyses were performed. It was found that [B]/[Zn] ratio altered both the m…
The metal tanning and semi-metal tanning potency of the first row transition metals was studied using hide powder. Transition metals show different levels of synergistic hydrothermal stabilisation in semi-metal tanning. Measurement of hydrothermal stability was carried out regularly in order to monitor the stability a…
Pyrrol-frei: Das abgebildete Azacalixphyrin, ein neuartiges isostrukturelles und isoelektronisches Porphyrin-Analogon, kann leicht in zwei Stufen synthetisiert werden. Die Verbindung ist aromatisch, absorbiert über den gesamten sichtbaren Spektralbereich und ist dank ihres ungewöhnlichen doppelt-zwitterionischen Chara…
Three series of water-soluble semi-rigid thermo-responsive polymers with well-defined molecular weights based on mesogen-jacketed liquid crystal polymers, poly[bis(N-(2-hydroxypropyl) pyrrolidone) 2-vinylterephthalate] [P(2-HPPVTA)], poly[bis(N-(1-methyl-2-hydroxyethyl) pyrrolidone) 2-vinylterephthalate] [P(1-M-2-HEPV…
In this paper, we report the synthesis of cadmium cobaltite nanoparticles (CCNs) and their characterisation by X-ray diffraction (XRD), field emission scanning electron microscope (FE-SEM) and transmission electron microscope (TEM). The particles are spherical in shape and the average particle size is of the order of…
The last half century has witnessed the development of synthetic plastics from petroleum resources, and more than 300 million tons of synthetic plastics are annually produced at present. The recently increased consumption of petroleum resources has led to environmental prob‐ lems such as a depletion of the resources a…
The split-field finite-difference time-domain (SF-FDTD) method for one-dimensionally periodic structures is extended to include the coefficient-tensor description of second- and third-order nonlinear-optical media. A set of nonlinear equations related to the split-field values of the electric field is established. An…
Optically based radiation detectors in various fields of science still suffer from low resolution, sensitivity and efficiency that restrict their overall performance. Quantum dots (QD) are well-suited for such detectors due to their unique optical properties. CdTe QDs show fast luminescence decay times, high conversio…
Carbon-based nanomaterials such as graphene, a layered two-dimensional (2D) crystal, carbon nanotubes and carbon nanofibers have been explored extensively by researchers as well as the semiconductor industry as viable alternatives to silicon-based complimentary metal-oxide semiconductor transistors. Besides nanoscale…
Abstract Micro‐porous propellants containing titanium powder were obtained by supercritical CO2 (SC CO2) foaming technique. The morphologies of the micro‐porous propellants were characterized by scanning electron microscopy (SEM) and energy‐dispersive X‐ray spectroscopy (EDS) measurement. The burning rate, the impetus…
Abstract The novel synthetic procedure for wüstite nanoparticles with cubic shape was developed in the presence of a large amount of oleylamine and oleic acid against Fe precursor. The pretreatment under reduced pressure at 130 °C facilitated the formation of rather larger particles, 82 nm, by removing vapor during th…
Abstract New lanthanide‐containing ionic liquids (ILs) based on thiocyanate complexes of the type [BMIM]x–3[Ln(NCS)x(H2O)8–x] (BMIM = 1‐butyl‐3‐methylimidazolium; x = 6,7,8) have been reported in recent studies. These complexes are highly efficient for dissolving lanthanide complexes within ILs. Until now, only partia…
Abstract In this study, conventional WC-12Co cermet coatings were deposited on AZ91 magnesium alloy using High Velocity Oxy-Fuel spray method. The effects of different coating thicknesses (60 and 120 µm) and wear loads (20 and 30 N) on tribological properties of AZ91 magnesium alloy coated with WC-12Co were investigat…
We describe the synthesis and structural characterization of the unprecedented [Bi4Fe3(CO)9] cluster, the low-valent Bi atoms of which are involved in the types of previously not identified intermolecular Bi···π(arene) and ΔBi···π(arene)interactions. Different coordination modes of arene rings bound to Bi atoms were d…
Optically Accelerated Formation of One- and Two-Dimensional Holographic Surface Relief Gratings on DR1/PMMA
Bi-axially textured Sm 0.2 Ce 0.8 O 1.9-x (SCO) single buffer tape with the length of 110 cm and the thickness of 150 nm, has been prepared on textured NiW(200) alloy substrate by using the polymer assisted chemical solution deposition (PACSD) method combined with slot-die coating technique for REBCO coated conductors…
We present results from ab-initio, self-consistent local density approximation (LDA) calculations of electronic and related properties of zinc blende indium phosphide (InP) and gallium phosphide (GaP) . We employed a LDA potential and implemented the linear combination of atomic orbitals (LCAO) formalism. This impleme…
SUMMARY: Only recently the first resources devoted to the functional annotation of proteins at the domain level started to appear. The next step is to develop specific methodologies for predicting function at the domain level based on these resources, and to implement them in web servers to be used by the community. I…
