In this work, we consider fractal substrates for Surface Enhanced Raman Scattering measurements. The shape of the substrates is based on self-similar space filling Hilbert curves, which possess properties of both one dimensional and two dimensional geometries. The dielectric response of a doped semiconductor nanostruc…
High-performance, top-gated, organic, nanofloating gate memory (NFGM) devices fabricated using spatially well-distributed metallic nanoparticles as a floating gate and dielectrics with long charge relaxation properties are reported by Kang-Jun Baeg, Yong-Young Noh, Dong-Yu Kim, and co-workers on page 3503. The organic…
High-efficiency AlGaN-based 355 nm UV light-emitting diodes (LEDs) grown on low-dislocation-density AlGaN/sapphire templates with an output power of 9.8 mW (22.7 mW) at a DC current of 40 mA (100 mA) are reported. The corresponding maximum external quantum efficiency and maximum power efficiency are 7.2 and 6.5%, resp…
Capillary force of a liquid drop embedded in a microfiber has great influence on the mechanics behavior of the microfiber. In this study, we investigated the buckling and finite deformation of a microfiber filled with a droplet. First, the critical load for the buckling of the microfiber was presented under the combin…
We report a systematic study of the thickness dependence of the resistivity tensor of epitaxial thin films of magnetite (Fe3O4). We find that decreasing film thickness decreases the relative magnitude of the terms related to crystal symmetry but increases their field dependence. We attribute this behavior to the prese…
An experiment designed to measure the atomic oxygen (AO) erosion profile of scattered AO was exposed to Low Earth Orbital (LEO) AO for almost four years as part of the Materials International Space Station Experiment 1 and 2 (MISSE 1 and 2). The experiment was flown in MISSE Passive Experiment Carrier 2 (PEC 2), Tray…
Statistics-based optimization of conditions for enzymatic production of collagen hydrolysates from a low-value Acaudina molpadioides was carried out, and their activities were also evaluated. The highest hydrolysis degree of collagen was 17.01% when substrate concentration, temperature and pH were 34.3 g/g (dry sea cu…

This paper describes a scientific workflow for ab initio calculations of elastic coefficients (Cij) of crystalline materials implemented in the VLab Cyberinfrastructure [da Silveira et al., 2008]. This workflow has recently been upgraded to treat crystals of all symmetries and integrated in the XSEDE. First we review…
THE THERMODYNAMIC MODELING OF THE URANIUM-OXYGEN. The thermodynamic modeling of the uranium-oxygen (U−O) system, which is of first importance in the development of a nuclear thermodynamic database, has been performed. The thermodynamic properties of the phases present in the U−O system are described using the compound…
Within the scope of the self-consistent-field (SCF) and mean-SCF approximations, the Matsubara–Kanzaki–Krivoglaz lattice-statics method as well as the Krivoglaz–Clapp–Moss approach, the kinematic diffuse scattering intensities near the Bragg reflection caused by the atomic short-range order (taking into account the lo…
Porous carbon materials have attracted interest recently as they are potential candidates for largenumber of applications especially in catalytic supports, battery electrodes, capacitors, gas storage and biomedicalengineering applications. As porous carbons are mostly amorphous in nature, a little presence of sp2 carb…
Sub-gigahertz ferromagnetic resonance (FMR) is investigated in a magnetic tunnel junction (MTJ) with small anisotropy fields. Distinct FMR spectra down to 0.36 GHz are obtained by applying an external field that cancels out the anisotropy. A macrospin model simulation reveals that the difficulty in obtaining a smaller…
MHF1 and MHF2 are histone-fold-containing FANCM-associated proteins. FANCM is a Fanconi anemia (FA) complementation group protein. We previously obtained high-resolution structures of MHF1-MHF2 (MHF) and MHF in complex with a fragment of FANCM (MHF-FANCM-F). Here, we use small angle X-ray scattering (SAXS) to investig…
We obtained high-quality AlGaInN/GaN quantum wells (QWs) with a 385 nm emission by adding Al sources to GaInN QWs grown at a low growth pressure of 150 mbar. When AlGaInN QWs were grown at a relatively high growth pressure of 400 mbar, a considerable amount of peculiar trench-shaped defects were observed on the surfac…
Three-way catalysts, a component of automobile converters, can control auto exhaust emissions by its capacity of converting CO, un-burnt hydrocarbon and oxides of nitrogen (NO x ) into less harmful CO2, H2O and N2 simultaneously. This process is efficient only when the A/F ratio is at 14.7. To widen the ratio for bett…
In recent years, renewable energies attract considerable attention due to the inevitable end of fossil fuels and due to global warming and other environmental problems. Photovoltaic solar energy is being widely studied as one of the renewable energy sources with key significance potentials and a real alternate to foss…
Examination of the thermodynamic constraints for the carbothermic reduction of iron-free kaolinite, Al2Si2O5(OH)4, or of its calcination product mullite, Al6Si2O13, either at atmospheric pressure or under vacuum of 10−3 to 10−5 bar, indicates the conditions required at equilibrium to produce either elementary Al or Al…
The technology of forced MAG welding of steels, based on the application of welding materials in the form of nanostructured electrode wires with the microcomposite coating of ultra- and nanodisperse particles of halides in the metallic matrix, is described.
The high-${T}_{c}$ alkali doped iron selenide superconductors K${}_{x}$Fe${}_{2\ensuremath{-}y}$Se${}_{2}$ have been recently shown to be intrinsically phase separated into Fe vacancy ordered block antiferromagnetic regions and superconducting regions at low temperatures. In this work, we use a microscopic five orbita…
