Our periodic orbit resonance (POR) results on quasi-two-dimensional (q2D), highly anisotropic q2D and quasi-one-dimensional (q1D) organic conductors are reviewed together with our rotational cavity magneto-optical measurement system. Higher order POR up to seventh order has been observed in the q2D system (BEDT-TTF)2B…

The shape-memory composite belt with a TiNi-SMA wire fiber and a polyurethane-SMP sheet matrix was fabricated. The bending actuation characteristics of the belt were investigated by the thermomechanical tests. Residual deflection obtained by cooling under constant maximum deflection is close to the maximum deflection.…
Extreme ultraviolet interferometric lithography (EUV-IL) is a powerful nanopatterning technique, exploiting the interference of two beams of short-wavelength radiation (13 nm) to form high-accuracy fringe patterns. Transmission diffraction gratings of appropriate period (40-100 nm) are used to form the beams; the subs…
Among his many extraordinary accomplishments, Kelvin was a pioneer of crystallography, elasticity and materials science. These interests came together to inspire his speculation on the nature of the ether in 1887. He conceived it to be an ordered liquid foam, of minimal surface area. Kelvin's ideal structure of foam h…
Abstract The von Neumann – Mullins relation has been extended to higher dimensions by MacPherson and Srolovitz. Their exact solution relates the rate of volume change of an individual grain in a 3-dimensional isotropic polycrystal to its mean width and total length of triple lines (assuming isotropic boundaries). The…
In order to study the magnetic interactions influence on the relaxation processes in superparamagnetic media, the magnetostatic measurements were carried out for the granular (CoFeB)x-(SiO2)1-x films with x values near percolation threshold. The observed temperature dependences of the coercivity for the samples magnet…
We report on the electric-field tuning of a magnetic phase transition temperature ( T L ) in multiferroic Ni 3 V 2 O 8 thin films. The simultaneous magnetic and ferroelectric transition in Ni 3 V 2 O 8 exhibits a clear dielectric anomaly; we monitored T L under applied electric and magnetic fields using dielectric mea…
Abstract magnified image In 1,1,1,2,3,4,4,5,5,5‐Decafluoropentane using 2‐phenylpyridine N‐oxide as donor ligand, the enantioselectivity of the Jacobsen–Katsuki epoxidation is improved up to 10% ee as compared to established protocols.
The influence of parameters of the porous structure and the surface layer composition of the xerogels containing 3-marcaptopropyl and alkyl groups on their sorption properties toward the Hg 2+ ions and the stability constants of the formed complexes, which are calculated using the model of chemical reactions, is studi…
The binding energies and related energies of associative desorption for oxygen on close-packed ( W (110), Mo (110), and Ru (0001)) and furrowed ( W (112), Mo (112), and [Formula: see text]) surfaces have been calculated by DFT method with generalized gradient approximation for exchange-correlation potential in the rev…
Fully understanding the environmental fate of tungsten is an ongoing challenge from an analytical perspective, due to the lack of effective laboratory methods for quantifying tungsten in soil. Developing the methods necessary to accurately and consistently monitor tungsten in soil matrices is essential for understandi…
The “islands” of ZnO nanocrystals on amorphous monodisperse 200 nm SiO2 spheres (core-shell particles) were obtained by simple one-step technique based on low-temperature crystallization from liquid phase. The influence of starting reagents types and concentration of zinc ions in the reaction mixture on the morphology…
The oxidizing ambient was built using high pressure H2O vapor at 550 °C. For the solid phase crystallization (SPC) polycrystalline silicon (poly-Si) that is annealed for 1 h at 2 MPa, the oxide thickness is about 150 Å. The oxide layer is approximately 90 Å above the original surface of the poly-Si and 60 Å below the…
As a new energy storage device, ultracapacitors are able to attain greater energy densities while still maintaining the characteristic high power density of conventional capacitors. As a result, ultracapacitor based power electronics system will become an attractive power solution to an increasing number of applicatio…
We present a method for measuring all eight parameters (including the signs) of the Jones matrices of liquid-crystal displays. The method can be applied to measure the Jones matrices for all addressable gray levels thus delivering the specifications needed for calculating characteristic curves for arbitrary input and…
Abstract Electrocapillary curves (surface tension γ as a function of the electrode potential E) for a series of room-temperature ionic liquids (RTILs) were measured using a mercury dropping electrode with the drop-weight (drop-volume) technique. The curves γ = f (E) for the Hg/RTIL interface have one maximum and may b…
Carbon and nitrogen dual doped TiO(2) (C-N-T) powders were obtained by annealing TiCN powders in an air atmosphere. The obtained C-N-T powders change from the anatase dominant phase to a pure rutile structure when the annealing temperature increases from 500 to 950 degrees C. The average grain size ranges from about 1…
OBJECTIVE: To study the possibility of primary human chondrocytes culture in gelatin scaffold and the effects of exogenous HA on chondrocyte differentiation and synthesis of the hyaline-like extracellular matrix. MATERIAL AND METHOD: Cartilage tissue was engineered by using primary human chondrocytes with HA-treated g…
