The influence of aluminium upon continuous cooling transformation (CCT) diagrams for hot rolled ferrite–martensite dual phase steel is investigated, with continuous cooling experiments performed through the use of dilatometry. Results indicate that additions of aluminium significantly raise the Ar3 and Ar1 temperature…
Scanning tunneling microscopy is used to study monolayers of 1-adamantanethiolate as they are exposed to gas-phase atomic hydrogen. H-atom reaction results in complete removal of the organic monolayer. The relaxation of the reconstruction present at the gold–sulfur interface results in the formation of gold-atom islan…
Reaction of Ni(NCS)2 with bis(3-aminopropyl)amine (dpt) and pyridine (pyr) in water and molar ratios leads to the formation of the new polymorphic modifications [Ni(NCS)2(dpt)(pyr)] (1a and 1b). Slight variation of the reaction conditions results in the formation of the new nickel(II) thiocyanato coordination compound…
The purpose of this paper is to present an analysis of the impact of solid particles on the development of cavitating flow conditions around a hydrofoil. Experimental studies have been conducted in a cavitation tunnel with three different mixtures of particles and water. We used particle-like properties such as are fo…
Bacillus subtilis possesses carbon-flux regulating histidine protein (Crh), a paralog of the histidine protein (HPr) of the phosphotransferase system (PTS). Like HPr, Crh becomes (de)phosphorylated in vitro at residue Ser46 by the metabolite-controlled HPr kinase/phosphorylase HPrK/P. Depending on its phosphorylation…
Protein kinases are key signaling enzymes that catalyze the transfer of γ-phosphate from an ATP molecule to a phospho-accepting residue in the substrate. Unraveling the molecular features that govern the preference of kinases for particular residues flanking the phosphoacceptor is important for understanding kinase sp…
A gold (Au) line and space (L/S) grating antenna for the silicon-on-insulator MOS (SOI-MOS) photodiode is investigated. The SOI-MOS photodiode has the advantages such as high-speed operation, large voltage gain per electric charge, and small dark current. However, its light sensitivity is usually very low due to the s…
The cultivated species of the wild autochthonous Asparagus officinalis in Andalusia in Spain is commonly called "triguero" asparagus. This vegetable has traditionally been very much appreciated for its organoleptic and nutritional characteristics. This study has been designed to evaluate the potential effect of differ…
We propose a parameter design of the parallax barrier (PB) based on the color moiré patterns in autostereoscopic displays. First, the display device and the PB are approximated as two corresponding binary gratings. In order to obtain different corresponding predominant Fourier low-frequency terms, the superposition of…
Configurational thermodynamics of the Fe-Cr sigma phase is investigated on the basis of an Ising-type configurational Hamiltonian and a single-site mean-field model for the free energy. The parameters of the statistical models are obtained from efficient first-principles calculations using different computational tech…
The aim of this study was to prepare hydrogel disc implants containing cisplatin from hydroxyethyl methacrylate (HEMA) and methyl methacrylate (MMA). To control drug release, the monomers were cross-linked with ethyleneglycol dimethacrylate (EGDMA). Implants were characterized by FTIR, DSC and SEM and evaluated for dr…
Various carbon materials with a characteristic morphology and pore structure have been produced using template methods in which a carbon-template composite is once formed and the characteristic features derived from the template are generated after the template removal. In this study, hemoglobin, which is a natural co…
Intense studies of a wide-gap direct-zone semiconductor represented by GaN wurtzite crystals doped with rare-earth ions, namely, Eu, Er, Sm, and Tm, suggest the development of an alternative (compared to that with the use of InGaN layers) technology of fabrication of light-emitting diodes of white color. The opportuni…
A general design is presented for a stimulus-responsive small molecule that is capable of responding to a specific applied chemical or physical signal by releasing two different types of pendant small molecules and a colorimetric indicator simultaneously. A key aspect of this design is the ease with which these reagen…
Room-temperature crystal structures of triammonium hexafluoroaluminate, (NH(4))(3)AlF(6) (I), and triammonium oxopentafluorotitanate, (NH(4))(3)TiOF(5) (II), were refined, and the crystal structures of dirubidium potassium oxopentaflourotitanate, Rb(2)KTiOF(5), at 297 K (III) and 218 K (IV) were determined using singl…
Abstract High Al‐composition (Al = 51%) and low Al‐composition (Al = 20%) AlGaN‐channel high‐electron‐mobility transistors (HEMTs) on AlN layers with very high carrier concentration were demonstrated. In two types of HEMTs, 2‐dimensional electron gases (2DEG) were clearly observed and peak carrier concentration and sh…
A new I(-)/(SeCN)(2) redox mediator has favorable properties for dye-sensitized solar cells (DSCs) such as less visible light absorption, higher ionic conductivity, and downward shift of redox potential than I(-)/I(3)(-). It was then applied for DSCs towards increasing energy conversion efficiency, giving a new potent…
Template-based methods for predicting protein structure provide models for a significant portion of the protein but often contain insertions or chain ends (InsEnds) of indeterminate conformation. The local structure prediction "problem" entails modeling the InsEnds onto the rest of the protein. A well-known limit invo…
Abstract Pd nanoparticles (NPs) with a mean size of 10–12 nm are dispersed on the surface of SiC nanowires (NWs) by a cyclic voltammetric deposition method, and employed as an electrocatalyst for methanol oxidation. The high dispersion and small size of supported Pd NPs enable the catalyst to have an electrochemical a…
Collision-induced dissociation (CID) of deprotonated hexose-containing disaccharides (m/z 341) with 1-2, 1-4, and 1-6 linkages yields product ions at m/z 221, which have been identified as glycosyl-glycolaldehyde anions. From disaccharides with these linkages, CID of m/z 221 ions produces distinct fragmentation patter…
