Nitrous oxide (N2O) emissions from nitric acid production worldwide have been estimated at about 400,000 t/a, equivalent to 120 million t/a CO2e, making nitric acid manufacture the largest single industrial process source of N2O. Uhde's NOX and N2O abatement technology has been developed to permit high rates of N2O ab…
The hysteretic differential susceptibility in both cases magnetization and demagnetization processes was modeled for Ni 0.58 Zn 0.42 Fe 2 O 4 nanocrystalline and Fe 3 O 4 nano wire arrays. It was formulated hysteretic loop of nanoscale magnetic materials in both magnetization and demagnetization processes. Energy loss…
Ottoite, Pb 2 TeO 5 , is a new tellurate from Otto Mountain near Baker, California. Most of the mining on Otto Mountain occurred between 1940 and 1970 and is attributed to Otto Fuetterer, for whom the mountain is now named. The new mineral occurs on fracture surfaces and in small vugs in brecciated quartz veins, which…
Abstract Cobalt titanate (CoTiO 3 ) powder was prepared by a modified sol‐gel method. The precursor solution could be prepared by cobalt acetate and titanium isopropoxide using various solvents either with or without HCl. After post‐heat treatment in air from 500 to 900 °C, CoTiO 3 powder with increasing crystallinity…
We report a miniature rotary-linear piezoelectric actuator with a single cubic stator of side length 3.5 mm which can generate rotary motion around the center axis and linear motion in the axial direction. The stator is fabricated as a single metallic cube of side length 3.5 mm with a 2.5-mm diameter through-hole and…
The efficiency of multi-watt ultraviolet radiation generation by harmonics processes in β-BaB 2 O 4 (BBO) can be improved by reducing thermal dephasing. The dephasing arises from local heating of BBO by the linear absorption of green (second harmonic) and ultraviolet (fourth harmonic) radiation by crystal defects that…
The results of studies of the structure of chemically modified detonation-synthesized nanodiamond (ND) particles by a set of physical and chemical methods are reported. It is shown that the crystal structure, size, and the paramagnetic properties of the particles persist during chemical modification processes. No nond…
Abstract Electrospun micro‐ and nanofiber scaffolds have gained interest in biomedical applications, especially in tissue engineering, because they can be used to reproduce the structure of the extracellular matrix (ECM) of natural tissue. The selection of the solvent is an important factor which affects the diameter,…
Tailoring tissue engineering strategies to match patient- and tissue-specific bone regeneration needs offers to improve clinical outcomes. As a step toward this goal, osteogenic outcomes and metabolic parameters were assessed when varying inputs into the bone formation process. Silk protein scaffolds seeded with human…
Single crystals of rubrene were grown by slow cooling of solutions in various solvents. Hexagonal single crystals were obtained from p -xylene, whereas parallelogram-shaped crystals were grown from aniline. Both types of crystal were obtained from propan-1-ol. Single-crystal X-ray diffraction analyses showed that the…
Motivated by the bad metal behavior of the iron pnictides, we study a multi-orbital t- J 1 - J 2 model and investigate possible singlet superconducting pairings. Magnetic frustration by itself leads to a large degeneracy in the pairing states. The kinetic energy breaks this into a quasi-degeneracy among a reduced set…
The process of acoustic emission during the sliding friction of X120Mn12 (DIN EN Standard) manganese steel has been studied. The coefficient of sliding friction has been determined in the absence of lubricants and the parameters of generated sound have been measured. A relationship between the acoustic emission spectr…
We describe a fixture that allows electrochemical devices to be studied under electrical bias in the type of vacuum systems commonly used in surface science. Three spring-loaded probes provide independent contacts for device operation and the characterization in vacuum or under in situ conditions with reactive gases.…
The effects of particle size, structure, microstrain, and cation distribution on magnetic property of nanosized Ni0.35Zn0.65Fe2O4 prepared through high-energy ball milling have been explored by a wide variety of experimental technique namely, x-ray diffraction, high-resolution transmission electron microscopy, dc magn…
Abstract The effect of hydrogen on the mechanical behaviour of steels is twofold: it affects the local yield strength and it accelerates material damage. On the other hand, the diffusion behaviour is influenced by the hydrostatic stress, the plastic deformation and the strain rate. This requires a coupled model of def…
The first-order reversal curves (FORC) distribution of PbZr(0.52)Ti(0.48)O3 thin films was characterized as a function of film thickness. It was found that the thickness dependence of the small-field dielectric constant is due primarily to differences in the domain wall contributions to the properties. The irreversibl…
Lung cancer is still one of the leading causes of malignancy related deaths worldwide despite recent advances in diagnosis and therapy. Among various biomarkers detected in cancerous cells, the epidermal growth factor receptor (EGFR) plays a key role in initiation/promotion of several malignancies. Thus, a number of s…
BACKGROUND: Electrospun nanofibers have been utilized in many biomedical applications as biomimetics of extracellular matrix proteins that promote self-organization of cells into 3D tissue constructs. As progress towards an artificial salivary gland tissue construct, we prepared nanofiber scaffolds using PLGA, a biode…
Bromide, Br − , adsorption behavior was investigated on amorphous Al and Fe oxide, montmorillonite, kaolinite, and temperate and tropical soils. Bromide adsorption decreased with increasing solution pH with minimal adsorption occurring above pH 7. Bromide adsorption was higher for amorphous oxides than for clay minera…
The paper presents experimental data on fabrication, optical, and photothermal properties of silver nanocubes and gold-silver nanostructures based on silver cube templates. The silver cubes were obtained using polyol synthesis with a sulfide-mediated reduction of silver nitrate by ethylene glycol in the presence of po…
