Using synthetic chemical approaches, it is now possible to synthesize transition metal carbides nanoparticles with morphology, where the transition metal layers are embedded with intervening layers of carbon atoms. A composite material consisting of Co2C and Co3C nanoparticles has been found to exhibit unusually large…
We report the synthesis of a room temperature ferromagnetic Mn-Ge system obtained by simple deposition of manganese on Ge(001), heated at relatively high temperature (starting with 250 °C). The samples were characterized by low energy electron diffraction (LEED), scanning tunneling microscopy (STM), high resolution tr…
This article is aimed at evaluating three designs of cylindrical-type electrostatic precipitators that might be installed at the output of household boilers in order to reduce the pollution due to burning wood or fossil fuels. The first design is the “standard” precipitator, which consists in a thin copper wire (0.16…
Coconut Shell Powder (CSP) was derived from industrial Making Anti-Mosquito can potentially be used as filler in materials composite. The investigation on the utilization of CSP as filler in a polyester matrix has been done with the purpose to obtain the best CSP fillers size in Unsaturated Polyester (UPR) composites…
Digital technologies have transformed the way many creative works are generated, disseminated and used. They have made cultural products more accessible, challenged established business models and the copyright system, and blurred the boundary between producers and consumers. This unique resource presents an up-to-dat…
The present research devoted to the investigation of the corrosion behavior of AZ61A FSW welds in accelerated conditions, including the influence of salt fog environmental parameters such as chloride ion concentration, pH, and duration of exposure. Significant numbers of tests were carried out that make possible to cr…
Temperature-programmed oxidation (TPO) was used to investigate the mechanism of lubricant-derived deposit formation on metal surfaces. The relationship between the crystalline structures of different carbonaceous specimens, along with their chemical reactivity, was used to distinguish between more reactive and less re…
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…
