We have systematically investigated the effect of Ni substitution on the structural and magnetic properties of NdCoO3. Single phase nature and orthorhombic Pbnm structure is confirmed by the Reitveld refinement of X-ray diffraction data in all samples. X-ray absorption near edge spectroscopy of Co and Ni K-edges revea…
Abstract The influence of low‐level silver (Ag) additions (0.12 and 0.5 wt%) to magnesium alloy AZ91 were studied in terms of electrochemical response and hardness. These properties were reconciled with microstructural analyses, indicating that 0.12 wt% Ag was capable of imparting an increment in hardness, with no sig…
The magnetism and stability of monodoped and codoped ZnO with transition metal (TM = Sc, Ti, V, Cr) or light element (LE = C, N) and their compensated (Sc+N, Ti+C) or noncompensated n-p (Sc+C, Ti+N, V+C, V+N, Cr+C, Cr+N) pairs are studied via spin-polarized density functional theory calculations. The ferromagnetic ord…
In the present study, Zn1−xNixS (x = 0.0–0.8 mol%) nanoparticles were prepared through the chemical route and the synthesis involved the mixing and drying of zinc acetate and sodium sulphide in an appropriate ratio with the addition of Ni2+ at a proper concentration. The structural and spectroscopic studies are invest…
A facile electrochemical synthesis of poly ( N -methyl pyrrole) (PNMP)/single wall carbon nanotubes (SWNTs) composite nanofibrillar matrix has been demonstrated. The composite nanostructure exhibits efficient room temperature sensing of ammonia down to 1 ppm. Towards probing the effect of SHI irradiation on the sensin…
Hydrophobins are relatively small globular proteins produced by filamentous fungi. They display unusual high surface activity and are implied as mediators of attachment to surfaces, which has resulted in high scientific and technological interest. In this work we focus on kinetic and equilibrium aspects of adsorption…
With the help of electron spin-coherent-state, we theoretically investigate the quantum tunneling time of a Dirac electron through a rectangular potential-barrier in monolayer graphene. It is shown that the tunneling time, which is measured in terms of the electron-spin precession in the magnetic field confined in the…
In order to explore whether Ru can be replaced by inexpensive Fe in dye molecules for solar cells, the differences in the electronic structure of Fe- and Ru-based dyes are investigated by X-ray absorption spectroscopy and first-principles calculations. Molecules with the metal in a sixfold, octahedral N cage, such as…
The energy level alignment of the two organic materials forming the TTF/TCNQ interface is analyzed by means of a local orbital DFT calculation, including an appropriate correction for the transport energy gaps associated with both materials. These energy gaps are determined by a combination of some experimental data a…
This study designs and implements a proximity sensor consisting of inductive and capacitive sensing units. These two sensing units are vertically monolithic integrated on a single chip using the micro-fabrication processes. In addition, low-temperature fabricated nanoporous anodic aluminum oxide (np-AAO) is employed a…
Elucidation of unknown target proteins of a drug is of great importance in understanding cell biology and drug discovery. There have been extensive studies to discover and identify target proteins in the cell. Visualization of targets using drug-conjugated probes has been an important approach to gathering mechanistic…
Photoinduced desorption (PID) of N(2)O and CO from porous silicon (PSi) samples is reported. Both adsorbates exhibit unusually large cross sections for PID at 193 nm, up to 10(-15) cm(2), 2-3 orders of magnitude larger than the literature values for similar processes on flat Si. Under this UV irradiation, N(2)O molecu…
Abstract It was found that 2‐amino‐1,2‐diphenylethanol forms organogels with a wide variety of acidic compounds in a large number of organic liquids, in which short contacts such as CH–π hydrogen bonds play a key role in gel formation. This new kind of acid–base, two‐component organogelator has potential application a…
We investigate the phenomena of negative refraction and backward wave in pseudochiral mediums, with illustrations of Gaussian beams. Due to symmetry breaking intrinsic in pseudochiral mediums, there exist two elliptically polarized eigenwaves with different wave vectors. As the chirality parameter increases from zero,…
We show that the volume which can be held on the top of a pillar is dependent on the elevation of the pillar. When a spreading fluid encounters an edge between two inclined surfaces, the angle between them determines the hysteresis at the edge. To examine the changes in the hysteresis as a function of pillar height, c…
Nanofabrication of buried structures with dimensions below 5 nm and with controlled 3D-positioning at the nanoscale was attempted to open new routes to future nanodevices where single nanostructures could be systematically interfaced. A typical example is ultralow-energy ion beam synthesis where already the depth posi…
The compound Mn1.1Fe0.9P0.76Ge0.24 has been studied using neutron powder diffraction (NPD), differential scanning calorimeter (DSC), and magnetic measurements, in order to clarify the nature of the magnetic and structural transition and measure the associated entropy change (ΔS). The strongly first order transition oc…
The interfacial properties of the ferromagnetic (FM)/ferroelectric (FE) heterostructure La0.7Sr0.3MnO3/BaTiO3 (LSMO/BTO) have been investigated by employing spin wave resonance technique. In addition to the uniform ferromagnetic resonance, spin wave resonances with both body and surface wave modes are observed. The an…
We demonstrate a kind of wave pattern on the surface of floating liquids in a modulated ultrasound field. The waves are related to the liquid/solid phase transformation process. The nucleation sites of the eutectics locate at the center of these waves, and the eutectic growth direction is parallel to the propagation d…
A polycrystalline sample of Pr 0.7 Ca 0.3 MnO 3 is synthesized by the conventional solid-state reaction method and the phase formation is confirmed by x-ray diffraction. In this work, we addressed the phase competition issues in the vicinity of magnetic transition temperature and also established its correlation with…
