Epitaxial strain effect has been studied for Nd0.25Sr1.75MnO4 thin films on (100) surfaces of two different isostructural (single-layered perovskite) substrates, LaSrAlO4 and LaSrGaO4. Due to the anisotropic strain in the MnO2 plane, the orientation-controlled films were stabilized with the structure consistent with t…
We developed a simple methodology for a direct control of the height of carboxylated single-walled carbon nanotube (SWNT) forests. We found that the important step is a good control of the oxidation temperature of the nanotubes. SWNTs oxidation at different temperature was followed by Raman and X-ray photoelectron spe…
Abstract The non‐polar m‐plane InGaN/GaN light‐emitting diodes (LEDs) grown by metal‐organic chemical vapor deposition (MOCVD) on LiAlO2(100) substrates were investigated. The structure of LEDs is composed by GaN p–n junction and five InGaN/GaN multiple quantum wells (MQWs). They emit blue or green light, respectively…
The berry of Solanum aculeastrum Dunal. is used for treating diseases such as rheumatism, gonorrhea, breast cancer and other inflammatory-related ailments in South Africa. The aqueous extracts of the fresh, dried and boiled berries at doses of 1 and 10 mg/kg body weight was evaluated for anti-inflammatory and analgesi…
We perform systematic density-functional calculations on the self-catalytic effect and the nucleation mechanism of In adatoms on InP(111)B substrate during the initial growth of self-catalyzed InP nanowires. We first determine the equilibrium structure and stability of pure InP(111)B surface. The calculated surface fo…
A dermal tissue construct composed of human dermal fibroblasts and a chitosan sponge has been developed, targeted towards the treatment of diabetic nonhealing ulcers. The construct has been designed in a way that the dermal fibroblasts are arranged as a three-dimensional sheet adhered entirely on one side of the chito…
This paper reports dependency of specific heat and ballistic thermal conductance on cross-sectional geometry (tube versus rod) and size (i.e., diameter and wall thickness), in free-standing isotropic non-metallic crystalline nanostructures. The analysis is performed using dispersion relations found by numerically solv…
Wool is the most popular natural material. In the textile industries, a lot of waste wool fibres and their products induce actions which lead to the regeneration of wool keratin materials. However, the most significant limitations may be the poor fracture resistance of neat keratin materials. Traditionally, biopolymer…
Two-dimensional fractal and spherulitic patterns have been developed on microslides during the crystallization of amino acids in the absence and presence of glucose and agar-agar from their aqueous solutions. Lysine crystallized uniformly in the form of ringed spherulite, but in the presence of glucose it crystallized…
Abstract In this paper, a simple and convenient method based on impedance measurement has been proposed for the first time to evaluate the average porosity, pore radius, and internal surface area of macroporous silicon structure fabricated by electrochemical method. The porosity and the average pore radius have been o…
Silicon oxide nanodot arrays were fabricated using functionalized block copolymer templates and selective silylation. A polystyrene-b-poly(acrylic acid/acrylic anhydride) (PS-b-PAA/AN) thin film containing spherical nanodomains was used as a template to build nanoscopic silica structures. A PS-b-PAA/AN thin film was p…
Magnetoconductance (MC) is generally believed to be controlled by the ratio of singlet to triplet excited states. In this study, it is found that the MC magnitude of tris-(8-hydroxyquinoline) aluminum-based organic light-emitting diodes decreases substantially upon the introduction of narrow band gap fluorescent dopan…
We present a new probabilistic encoding of the conformational space of a molecule that allows for the integration into common similarity calculations. The method uses distance profiles of flexible atom-pairs and computes generative models that describe the distance distribution in the conformational space. The generat…
We present a kinetic Monte Carlo simulation based on ab initio calculations for the thermal desorption of oxygen from a Rh(111) surface. Several models have been used for the parametrization of the interaction between the adsorbed atoms. We find that models based on a parametrization with only pairwise interactions ha…
The current system of dose quantities in radiological protection is based, in addition to the absorbed dose, on the concepts of equivalent dose and effective dose. This system has been developed mainly with uniform whole-body exposures in mind. Conceptual and practical problems arise when the system is applied to more…
A microporous metal−organic framework (MOF), [Zn 2 L 2 (dabco)], was prepared using a long and rigid dicarboxylic acid, 1,4-bis(3-carboxylphenylethynyl)benzene (H 2 L), with some rotational flexibility, and an auxiliary bridging diamine linker, 1,4-diazabicyclo[2.2.2]octane (dabco). The MOF, based on a Zn paddle-wheel…
The 2-deoxy-D-ribose-5-phosphate aldolase gene from Hyperthermus butylicus was subcloned, overexpressed in Escherichia coli and purified to apparent homogeneity. Analysis of the sequence of gene revealed an open reading frame (ORF) of 672 base pairs encoding 237 amino acids predicted to yield a protein of molecular ma…

A route has been developed to disperse metal-containing phthalocyanine dyes in a non-polar medium based on amphiphilic block copolymer micelles of poly[styrene-block-(4-vinylpyridine)] (PS-b-P4VP) and poly[styrene-block-(acrylic acid)] (PS-b-PAA) copolymers. Polar P4VP and PAA efficiently encapsulate cobalt(II), manga…
Clear positive temperature coefficient resistor (PTCR) dc behavior has been shown in Pr-doped ZnO (0001¯)∣(0001¯) bicrystals by electrical characterization over an unprecedentedly wide temperature range between 40 and 1070 K. With subtraction of the PTCR dc, the admittance can be described by a deep trap level at 0.26…
