We theoretically investigate the applied magnetic field-angle dependence of the flux-flow resistivity ${\ensuremath{\rho}}_{\mathrm{f}}({\ensuremath{\alpha}}_{\mathrm{M}})$ for a uniaxially anisotropic Fermi surface. ${\ensuremath{\rho}}_{\mathrm{f}}$ is related to the quasiparticle scattering rate inside a vortex cor…
Trace elements, especially heavy metals, even at low concentrations (< 2 ppb) are considered to be one of the main sources of pollution in the environment, since they have a significant effect on ecological quality 1 . Among the metal contaminants, heavy metal ions such as Pb 2+ and Cd 2+ are the two major pollutants…
The purpose of this research is to analyze the effects of Dansam and Sappan wood extract to perform combination dyeing on silk fabrics, with respect to color changes, fastness (washing, dry cleaning, perspiration, rubbing and light fastness), and functionality (antibacterial activity and deodorization). Combination dy…
The mechanisms of charge balance and tuning of the color coordinates in blue phosphorescent organic light-emitting diodes were studied by controlling the emission zone and electroluminescence (EL) spectrum. On the basis of the findings, this paper discusses different hole-injection and mobility factors such as the thi…
Cu(Ga,In)Se 2 (CIGS) thin-films were fabricated by ion beam sputtering deposition (IBSD) via sequentially deposited CuGa, Cu, In and Se layers at different substrate temperatures. The advantage of this technique is that additional selenization can be omitted. The influence of substrate temperatures on the composition,…
Understanding the cellular target structure and thereby proposing the best delivery system to achieve sustained release of drugs has always been a significant area of focus in biomedical research for translational benefits. Specific targeting of the receptors expressed on the target cell represents an effective strate…
Poly(itaconic acid) was grafted on GG in aqueous medium under microwave irradiation using a catalytic amount of BPO. Grafted copolymers (GG-g-PIA) were characterized by FT-IR, TGA, and SEM techniques. The influence of microwave power, exposure time, and composition of the reaction mixture on extent of grafting was stu…
A series of polyamidoamine (PAMAM) dendrimers with tetrathiafulvalene (TTF) at the periphery (Gn-PAMAM-TTF), generation 0-2, were synthesized. These functionalized dendrimers exist as nanospheres with diameters around 80-100 nm in aqueous phase, which can encapsulate hydrophobic molecules. The terminal TTF groups can…
The first experimental evidence that fullerenes react with alkali-metal trichloroacetates through a nucleophilic addition-substitution route, yielding dichloromethylenefullerenes as the final products, is reported. The intermediates, C60 (CCl3 )(-) and C70 (CCl3 )(-) anions, have been isolated in their protonated form…
Abstract The degradation behavior of Zirconia – 20% carbon refractory was investigated during high temperature (1550 °C) contact with a casting mould meniscus slag containing 50% MnO, 25% SiO2, and 25% Al2O3. Using the sessile drop approach, the transient progress of corrosion reactions was investigated as a function…
Friction stir processing (FSP) was carried out for AE42 Mg alloy resulting in significant grain refinement and uniform dispersion of fine in situ precipitates. The average grain size was 20 μm for the as‐cast AE42 alloy, which was refined to 1.5 μm after FSP. Tensile testing revealed significantly higher modulus and y…
The effect of copper slag leaching was evaluated using Atomic Absorption Spectroscopy (AAS) immersed \nin three aqueous media such as tap water, sea water, and synthetic/artificial rain water. The mechanical \nand corrosion resistance properties of copper slag admixed concrete was evaluated using compression \ntest an…
Relative concentrations of the nine IPR-based (isolated-pentagon-rule) isomers of Yb@C82 are computed from the Gibbs energy derived from partition functions supplied with parameters from density functional theory calculations. A good agreement with experiment is found at elevated temperatures where the Yb-endohedrals…
Glucose sensors are essential tools for diabetes patients to use in monitoring their blood glucose levels. However, to be able to detect glucose in non-invasively collected physiological fluids, such as tears and urine, the sensitivity of these glucose sensors must be significantly higher than sensors that are current…
An original approach is proposed here to reversibly tune Mie scattering resonances occurring in random media by means of external low induction magnetic fields. This approach is valid for both electromagnetic and acoustic waves. The experimental demonstration is supported by ultrasound experiments performed on emulsio…
This work illustrates a two-step strategy for the fabrication of polymer/drug nanoparticles. Utilizing solvent/non-solvent precipitation and gaseous basification, composite nanoparticles with 0-100% drug loadings are fabricated. Drug release kinetics are dictated by nanoparticle composition allowing future tuning for…
A type of redox flow battery, based on lead (II) dissolved in the electrolyte, has emerged as possible system for energy storage. However, the formation of lead dendrite and the evolution of hydrogen in the last stage of charge have limited the application of soluble lead flow batteries. A comparison study on electroc…
The structure of the lamellar phase of aqueous pentaethylene glycol mono-n-dodecyl ether (C12E5) surfactant at various temperatures and molar fractions is studied by using united atom molecular dynamics simulations and nuclear magnetic resonance measurements. Namely, the simulation model is used to interpret the magni…
The chemical reactivity of the simple condensates 1 and 2, derived from 3-formylchromone, was studied towards some nucleophilic reactions.Reactions of compounds 1 and 2 with some nucleophilic reagents mainly proceed via nucleophilic addition at the exocyclic vinyl bond followed by either elimination or cyclization dur…
Abstract The Cr–Ni–Re system was investigated over the whole composition range using combinatorial fabrication methods combined with high‐throughput characterization techniques in order to establish its thin film phase diagram. After annealing at 940 and 1100 °C, the phase equilibrium was reached in the Ni‐rich part o…
