UNLABELLED: Waxy corn starch was esterified with 2-octen-1-ylsuccinic anhydride (OSA) using response surface methodology. The molecular structure and paste properties were also investigated. Results indicated that the optimum parameters for esterification were as follows: reaction period 4 h, temperature 36.7 °C, pH o…
The transmission spectra of polarized light waves in a photonic crystal/liquid crystal (PC/LC) cell placed between crossed polarizers and controlled by an electric or magnetic field have been studied experimentally and theoretically. Electro- and magneto-optical switching based on the interference of polarized defect…
We present spin pumping using a Heusler alloy Co2MnSi/Pt bilayer film. A spin current is produced by a ferromagnetic resonance (FMR) technique. The pure spin current injected into the Pt layer from the Co2MnSi layer is detected by the inverse spin-Hall effect (ISHE), which converts the spin current into an electric cu…
The need to achieve increasingly better performance in present and future tokamak devices has made plasma control increasingly important in tokamak engineering. When high performance and robustness are required, it is essential to adopt a model-based approach to design a control system. We introduce the basics of plas…
Abstract We realize ultrarapid inactivation of bacteria by modifying fine Ag nanoparticles with uniform size on mesoporous anatase films with high surface areas.
A novel method of electrical passivation of a Ge surface by an ultrathin SiO2/GeO2 bilayer is proposed as an effective method for fabricating metal–oxide–semiconductor (MOS) structures, which can be processed through the thermal etching of GeO2 by vacuum annealing and subsequent SiO2 deposition. We demonstrated the fe…
The annually necessary human bone grafts are in continuous grown due to the increasing of fractals, congenital and non-congenital diseases. Based on statistical reports (Murugan and Ramakrishna 2005), only in USA about 6.3 million fractures occur every year and about 550.000 of these require bone grafting. The most fr…
The least well known loading type is the impact loading that are affecting on to RC structures. Several impact tests have been used to demonstrate the relative brittleness and impact resistance of concrete and similar construction materials. However, none of these tests has been declared to be a Standard test, at leas…
Sodium acid sulfate (SAS) dip treatments were evaluated against a distilled water control and citric acid (CA) to compare its effectiveness in reducing enzymatic browning of raw, French-fry cut potatoes. Two separate studies were conducted with dip concentrations ranging from 0%, 1%, and 3% in experiment 1 to 0%, 2%,…
Electric-induced resistive switching effects have attracted wide attention for future nonvolatile memory applications known as resistive random access memory (RRAM). RRAM is one of the promising candidates because of its excellent properties including simple device structure, high operation speed, low power consumptio…
Cd1−xZnxS thin films at low Zn content were prepared both by chemical bath deposition (CBD) and vacuum co-evaporation. The X-ray fluorescence (XRF) and X-ray photoelectron spectroscopy (XPS) analysis were performed to determine the composition of the films, while the structural properties were investigated by X-ray di…
A new flux made of Li2WO4–B2O3 was used to grow YAl3(BO3)4 (YAB) crystals. The crystallisation region of YAB crystals was determined in the quasi-ternary system YAB–Li2WO4–B2O3. Large and transparent YAB crystals were grown by a high temperature top seeding method with Li2WO4–B2O3 as the flux. The volatility of Li2WO4…
The data on the standard thermodynamic functions of silver selenide (naumannite) determined by the EMF method with the electrolyte representing either silver chloride or a glycerol solution of KCl with AgCl are shown. The procedure of measurements with the mentioned electrolytes is developed.
The stress state of FePt thin films deposited at room temperature was controlled within the range from 1.01 GPa compressive to 0.18 GPa tensile before taking rapid thermal annealing (RTA). After the order–disorder transformation triggered by RTA at temperatures (Ta) from 650 to 800 °C for 5 min, the tensile-stressed f…
In this paper, we present the results of voltage-ramp dielectric breakdown and time-dependent dielectric breakdown experiments for contact-polysilicon control gate intra-level dielectric stacks. Lifetime distribution and area scaling are discussed statistically with the analysis of global and local space deviations us…
A TiO2@SiO2 hybrid support was prepared by the sol-precipitation method using n-octylamine as a template. The photocatalyst manganese phthalocyanine tetrasulfonic acid (MnPcS) was immobilized on the support to form MnPcS-TiO2@SiO2. X-ray diffraction (XRD) and UV-Visible diffuse reflectance spectra (UV-Vis DRS) were em…
Abstract A mixed‐valence cluster of cobalt(II) hexacyanoferrate and fullerene C60‐enzyme‐based electrochemical glucose sensor was developed. A water insoluble fullerene C60‐glucose oxidase (C60‐GOD) was prepared and applied as an immobilized enzyme on a glassy carbon electrode with cobalt(II) hexacyanoferrate for anal…
The X-ray diffraction and infrared spectroscopy data for MOCVD-hydride Al x Ga1 − x As:Si/GaAs(100) heterostructures and homoepitaxial GaAs:Si/GaAs(100) structures doped with Si to a content of up to ∼1 at % are reported. It is shown that, in the homoepitaxial heterostructures, the formation of alloys with Si yields a…
Optical reflectance and absorbance of gallium arsenide films formed on polycrystalline corundum, quartz glass, and copper foil are investigated in the energy interval of 1.1–6.2 eV. The films have been deposited from ablation plasma induced by a high-power ion beam. The exponential and interband absorbance spectra of…
Abstract Particle shape and size of an energetic material play a vital role in achieving explosive formulations with optimal performance that decides the realization of high bulk and theoretical maximum density (TMD) and mix fluidity during their processing. 3‐Nitro‐1, 2, 4‐triazol‐5‐one (NTO) is an insensitive therma…
