In this study, the water vapour sorption of Belmadur wood is fully investigated. The sorption isotherms were analysed using the Hailwood-Horrobin model. Belmadur wood was shown lower total sorption by 26.5%, polymolecular sorption by 23.9% and monomolecular sorption by 33.1% at saturation, compared with the untreated…
This paper presents the experimental results on space charge distribution in cross-linked polyethylene (XLPE) insulating material for 22 kV power distribution system cable by using pulse electroacoustic measurement technique (PEA). Numbers of XLPE insulating material ribbon having thickness 60 μm taken from unused 22…
This paper employs the multiple scales method and chaos theory for analyzing chaotic behavior of the voltage transformer (VT) with linear core loss model. It is shown that ferroresonance phenomenon in VTs can be classified as chaotic dynamics, including a sequence of bifurcations such as period doubling bifurcation (P…
Optical absorption in double-wall carbon nanotubes for light polarized perpendicular to the tube axis is studied by taking into account exciton effects and depolarization effects within an effective-mass theory. The Coulomb interaction is suppressed by not only intrawall screening effects but also interwall screening,…
A double layer of identical subwavelength metal patch arrays is experimentally shown to be electromagnetically chiral due to the evanescent coupling of the near fields between nonchiral layers---it exhibits ``evanescent handedness.'' Despite each layer being intrinsically isotropic in the plane with four mirror planes…
Ionic polymer transducers also known as ionic polymer metal composites belong to the family of electroactive polymer transducers. Electroactive polymers are flexible and lightweight devices that operate as sensors and actuators without having any internally moving parts. The absence of moving parts offers a more effic…

Within the framework of the Lifshitz-Slyozov-Wagner theory of Ostwald ripening, the amount of volume of the second (solid) phase in a liquid solution that is newly formed by recrystallization is investigated. It is shown that in the late stage, the portion of the newly generated volume formed within an interval from t…
Experiments simulating flooding scenario in various aqueous media for a long period were carried out to determine the adequacy of cement-clay composite for solidification/stabilization of spent organic radioactive liquid scintillator wastes. The final cement waste form blocks were immersed in three aqueous media, name…
Rheological measurements have been applied to study the tautomerization of the pharmaceutically active compound glibenclamide. The rate constant and activation energy of the imidic-acid-amide transformation have been successfully determined by monitoring the evolution of shear viscosity. The kinetic parameters from rh…
Photolysis and sonolysis of trichloroethylene (TCE) in water was investigated using a cup-horn, flow-through reactor system. Water containing titanium dioxide was deliberately contaminated with TCE. These solutions were irradiated with ultraviolet light (UV) and ultrasonic waves (US). The decrease in the TCE concentra…
High-density polyethylene/Mg 2 Al-layered double hydroxide nanocomposites with different ethylene-acrylic acid random copolymer/Mg 2 Al-layered double hydroxide master batches were prepared by melt-mixing. The effect of the ethylene-acrylic acid random copolymer melt index on the exfoliated/intercalated nanocomposite…
We study multiple scattering of electromagnetic waves by an array of parallel gyrotropic circular rods and show that such an array can exhibit fairly unusual scattering properties and provide, under certain conditions, a giant enhancement of the scattered field. Among the scattering patterns of such an array at its re…
Stitch-bonded, non-crimped fabric composites are among the most common forms of structural fiber-reinforced polymer composites. A complex three-dimensional finite element model is usually required for the accurate prediction of the mechanical properties of these composites. The objective of this work was to develop a…
Monte Carlo computer simulation is employed to determine the local, wave-number-dependent, high-frequency elastic properties of a Lennard-Jones fluid that is confined between two walls. In particular, the elastic constants are calculated from coarse-grained stress correlation functions and then related to the local fl…
We experimentally investigate the symmetry in the Hidden Order (HO) phase of intermetallic URu2Si2 by mapping the lattice and magnetic excitations via inelastic neutron and x-ray scattering measurements in the HO and high-temperature paramagnetic phases. At all temperatures the excitations respect the zone edges of th…
The elastic, thermodynamic and optical properties of Li3P have been studied for the first time using the plane-wave ultrasoft pseudopotential technique which is based on the first-principles density functional theory (DFT) with generalized gradient approximation (GGA). The optimized lattice parameters, independent ela…
An extremely strong room-temperature photocurrent- (PC- or ${I}_{\mathrm{PC}}$-) detected magnetic resonance (PCDMR) that elucidates transport and trapping phenomena in organic devices, in particular solar cells, is described. When monitoring the transient PCDMR in indium tin oxide (ITO)/poly(2-methoxy-5-(2\ensuremath…
Yohimbine (C21H27N2O3) is one of the most important indole alkaloid. Differential scanning calorimetry, natural bond orbital (NBO) analysis and dipole moment with hyperpolarizability have been performed for molecular characterization. Stability of the molecule arising from hyper conjugative interactions, charge deloca…
We examine the thermodynamic behavior of diblock copolymers representing the binary pairs of the ternary system: poly(dimethylsiloxane)/poly(ethylene -stat -propylene)/poly(styrene- ran -styrenesulfonic acid), D / E P / S S . We employ small-angle X-ray scattering, electron microscopy, and rheology to characterize the…
