This work presents results of the theoretical analysis as well as the results of experimental study on sensing structures with grating couplers. Grating couplers with a groove density of 1250g/mm were produced by us using the method of master grating embossing in a sol film. The waveguide films SiO2:TiO2 of high refra…
We report unique colloidal gel-glass coexistence in aqueous laponite dispersion (2% w/v) in the presence of 1-methyl-3-octylimidazolium chloride ionic liquid (IL, [C8mim][Cl], concentration 0.01 to 0.05% w/v), where both of the phases had identical nonergodicity and were dynamically interactive. With aging, the nascen…
Amperometric thick-film zirconia oxygen sensors are electrochemical devices in which the zirconia thick-film acts as both electrolyte and diffusion barrier. Their preparation involves temperatures of 1300–1400 °C to sinter the thick-film and reduce the through-porosity to a sufficiently low value to restrict oxygen di…
We have developed a cryogen-free critical-current ( I c ) measuring system comprising a conduction-cooled 8 T HTS magnet and convection-cooled sample, both cooled by commercial cryocoolers. The sample can be rotated and transport currents of up to 800 A delivered with less than 0.5 K temperature rise during the Ic mea…
Silica-based sol-gel coatings have gained attention in bone therapies and orthopedic applications, due to the biocompatibility and bioactivity, including a high potential for the controlled release both in vitro and in vivo. Bioactive materials are created to facilitate the biocompatibility of orthopedic implants. One…
The physical data regarding bremsstrahlung and neutrons produced in a steel shield by high-energy electron beams from a medical linear accelerator were investigated. These data are required to allow the accurate prediction of shielding performance for high-energy electron beams and in the design of radiotherapy facili…
In this study, mesoporous carbon nitride (MCN-1) was synthesized by using mesoporous silica SBA-15 as a template and applied, for the first time, to the adsorption of 1-ppm formaldehyde, an important indoor air pollutant. Ammonia treatment was conducted at 700 oC for additional change in the surface characteristics of…
With respect to the limited lifespan of glutaraldehyde-treated bioprostheses (BHVs) to date there is almost no alternative when heart valve replacement surgery is required and most advanced current research attempts to develop tissue engineered valve scaffolds to be implanted in vivo or after in vitro preconditioning…
Photopolymerization of poly(ethylene glycol) monomethacrylate (PEGMM) in two imidazolium based ionic liquids (ILs) differing with the anion size and H-bond accepting ability, i.e. 1-ethyl- -3-methylimidazolium tetrafluoroborate ([EMIm][BF4]) and 1-ethyl-3-methylimidazolium trifluoroacetate ([EMIm][ATF]) was investigat…
Considerable progress has been made with the development of REBCO coated conductors in recent years, and high performance conductors are available commercially. For many applications, however, the cost remains prohibitive, and AC losses discourage their selection for higher frequency applications. Chemical solution de…
We measure the switching probability distributions of the first and second switching in the stack of Bi 2 Sr 2 CaCu 2 O 8+δ and Bi 2 Sr 2 Ca 2 Cu 3 O 10+δ intrinsic Josephson Junctions. The saturation temperature of the first switching in Bi2212 is ~ 2 K. This temperature is almost same in Bi2223. It is a little highe…
For the improvement of superconducting properties of BaMO 3 (M=Zr, Sn, HQ-doped REBa 2 Cu 3 O y films, we focused on the T c reduction caused by lattice misfit between BaMO 3 and REBa 2 Cu 3 O y . We compared the influence on the Tc reduction of BaZrO 3 , BaSnO 3 and BaHfO 3 -doped SmBa 2 Cu 3 Or (SmBCO) films with va…
We try to understand the fact that fullerene film behaves as n-type semiconductor in electronic devices and establish a model describing the energy level alignment at fullerene/metal interfaces. The C60/Ag(100) system was taken as a prototype and studied with photoemission measurements. The photoemission spectra revea…
Ab initio molecular dynamics simulations are used to describe the diffusion of hydrogen in liquid aluminum at different temperatures. Quasi-instantaneous jumps separating periods of localized vibrations around a mean position are found to characterize the hydrogen motion at the microscopic scale. The hydrogen motion i…
The gas-phase reaction chemistry of the decomposition of monomethylsilane (MMS) has been studied in the presence of a heated metal filament in a hot-wire chemical vapor deposition (HWCVD) reactor. A 10.5 eV vacuum ultraviolet laser single-photon ionization time-of-flight mass spectrometry was employed in combination w…
An efficient phosphorescent white organic light emitting-diode with a red-green-blue tri-emitting-layer structure is reported. The host of the red dopant possesses a lower triplet-energy than the green dye. An interlayer step-wise triplet transfer via blue dye → green dye → red host → red dye is achieved. This mechani…
A method for reconstructing the spatial profile of the electric field along the thickness of a generic bulk solid-state photodetector is proposed. Furthermore, the mobility and lifetime of both electrons and holes can be evaluated contextually. The method is based on a procedure of minimization built up from current t…
Plasma-sprayed molybdenum coatings are used in automotive, aerospace, pulp and paper industries in order to guard the machine parts against wear and corrosion. In this work, an attempt has been made to study the effect of particle size on wear behaviour of molybdenum coated steel. Two types of Mo coatings were deposit…
We report data on the structure of liquid Al and an Al67Mg33 alloy obtained from state-of-the-art X-ray diffraction experiments and ab initio molecular dynamics (AIMD) simulations. To facilitate a direct comparison between these data, we develop a method to elongate the AIMD pair correlation function in order to obtai…
D-Amino acid oxidase (DAO) is structurally unstable and exhibits broad specificity to D-amino acids. In this work, we fabricated a stable liposomal DAO system with high apparent substrate specificity. Permeability of the membrane composed of POPC (1-palmitoyl-2-oleoyl-sn-glycero-3-phosphocholine) was highly selective…
