Poly (ethylene oxide) (PEO) based Nano-Composite Polymer Electrolyte (NCPE) membranes: (70PEO: 30KNO3) + x SiO2, where x = 0, 1, 2, 3, 5, 8, 10, 12 wt. (%), have been casted by hot-press/ solution free technique. Solid Polymer Electrolyte (SPE) composition: (70PEO: 30 KNO3) (wt. %), reported earlier as highest conduct…
Abstract Material degradation and ageing is of particular concern for fossil fuel fired power plant components. New techniques/approaches have been explored in recent years for Residual Life assessment of aged components and material degradation due to different damage mechanism like creep, fatigue, corrosion and eros…
The purpose of the present study was to explore the potential application of cyanines in photodynamic treatment. The photophysical features of four cyanines (KF570, HM118, FBF-749, and ER-139) were investigated by elemental and spectral analyses. Two malignant cell lines (MCF-7/WT and MCF-7/DOX) were used to test the…
The evolution of the recoverable (R) component of negative-bias temperature instability (NBTI) is examined, as a function of the number of stress and relaxation cycles, for the SiON, HfSiON, and HfO2p-MOSFETs. At typical NBTI oxide fields (~7 MV/cm), a steady and substantial decrease of the R component in the case of…
We discuss the drainage of a wetting film deposited on a vertical solid covered with a regular array of microposts. It is shown that the classical Jeffreys' law, observed on flat solid, is deeply modified by the texture: 1) the film thickness does not follow anymore a scaling law, as a function of time; 2) below a cri…
Thioredoxin and thioredoxin reductase can regulate cell metabolism through redox regulation of disulfide bridges or through removal of H(2)O(2). These two enzymatic functions are combined in NADPH-dependent thioredoxin reductase C (NTRC), which contains an N-terminal thioredoxin reductase domain fused with a C-termina…
Starch consolidation casting has been successfully used to produce porous ceramics with complex shapes at a relatively low producing cost. In this work, porous 3Y-ZrO2 ceramics were produced using two types of starch (corn and potato). Concentrated (50-52 vol. (%)) aqueous suspensions of the different 3Y-ZrO2-starch m…
A novel nanostructured composite, azide copper octa (3-aminopropyl)octasilsesquioxane (ASCA) was incorporated into a graphite paste electrode and the electrochemical studies were conducted with cyclic voltammetry. The cyclic voltammogram of the modified graphite paste electrode with ASCA (GPE-ASCA), showed one redox c…
Gadolinium substituted LiMn2O4 powders have been synthesised by molten salt route for application in lithium batteries. The thermal behaviour of precursor salts has been studied using thermogravimetry and differential thermal analyses. The formation of the compound is in the temperature range of 600–700°C. X-ray powde…
Abstract The oxidation behavior has been studied under both dry and wet oxidation atmosphere at 873 K to 1073 K. In dry atmosphere the oxidation resistance of these alloys has been described by the formation of a protective oxide FeCr 2 O 4 at 873 K to 973 K. At 1073 K, the kinetics are parabolic with fast growing oxi…
Abstract The use of waste materials from mineral ore processing has much potential for immobilizing pollutants such as arsenic (As) in natural soils and waters. The purpose of the present study was to investigate red mud (RM, a finely textured bauxite-ore residue) as a sequestering agent for arsenate and phosphate, in…
The effects of varying the laser power and the spot diameter of a laser beam on the magnetic properties, morphology, and deposition rate of Nd–Fe–B thick-film magnets fabricated by pulsed laser deposition (PLD) were investigated. Reducing the laser fluence on the target reduces the remanence and increases the Nd conte…
The real structure of samples of optical fluoride ceramics is studied by atomic force, scanning electron, and transmission electron microscopy. It is shown that the optical ceramic samples based on CaF 2 have a lamellar structure, and the distance between lamellae is 25–50 nm. Most likely, lamellae have a twin nature.…
The dominating conduction mechanisms through TiN/Zr1−xAlxO2/TiN capacitors have been investigated over a wide temperature range (25 K to 430 K) in order to obtain information about the traps which cause the current transport. Single positive charged oxygen vacancies are the principal transport sites which participate…
Fourier Transform Infrared microscopy (FTIR) has become an essential analytical tool available to scientists to study various materials.Specifically FTIR has been increasingly used to study cell wall developments in plants, investigate the efficiency of the surface modification of polymers, identifying contaminants, a…
Based on the embedded atom method (EAM) and molecular dynamics (MD) method, the mono-crystalline copper with different defects is investigated through tension and nanoindentation simulation. The single-crystal copper nanowire with surface defects is firstly studied through tension. For validation, the tension simulati…
GeO desorption from a GeO 2 /Ge stack is a critical concern in Ge metal oxide semiconductor field effect transistors (MOSFETs). In this contribution, we focus on a uniform-desorption region and unveil the GeO desorption mechanism from a GeO 2 /Ge stack by 73 Ge and 18 O isotope tracing in thermal desorption spectrosco…
Magnetic properties of Ru-deficient strain relaxed SrRuO3 films have been investigated. The ferromagnetic transitions drop off from 138 to 100 K with expansion of unit cell volume due to the Ru vacancies. A secondary transition starts appearing near to the bulk transition temperature of 155 K, indicating the two diffe…
Pure titania, zirconia, and mixed oxides (3–37 mol.% of ZrO 2 ) are prepared using the sol-gel method and calcined at different temperatures. The calcined samples are characterized by Raman spectroscopy, X-ray powder diffraction, scanning electron microscopy, transmission electron microscopy, and nitrogen adsorption p…
Research data have demonstrated that the P demand of coffee (Coffea arabica L.) is similar to that of short-cycle crops. In this context, the objective of this study was to evaluate the influence of annual P fertilization on the soil P status by the quantification of labile, moderately labile, low-labile, and total P…
