The expression for the mutual interaction force between two pulsating gas bubbles immersed in an incompressible and inviscid fluid is derived assuming that the distance between the bubbles is comparable to their sizes. The results of numerical calculations for air bubbles in water are presented. They show that at smal…
Abstract This paper deals with the conductivity of binary polymer composites filled with an electronically conductive material. A “dynamic cluster model” is offered to describe the conductivity of such polymer composites in the highly filled region, i.e. above the percolation threshold. The model is based on the follo…
An ‘in situ’ deposition method is presented where combination of solutions of aniline monomer and an oxidizing agent leads to the growth of uniform polyaniline (PAn) conducting thin films on submerged substrates. The PAn films can be deposited on a variety of substrates including glass and organic materials. Film thic…

The Anderson model of local-state conduction electron mixing is applied to the p roblem of interlayer magnetic coupling in metallic multilayered structures with palladium (Pd) spacer layers. An oscillation period of $5$ spacer monolayers and the tendency towards ferromag netic bias of the interlayer magnetic coupling…

Mechanical properties of titanium-zirconium binary alloys were investigated in order to reveal their possible use for new biomedical materials and to collect useful data for alloy design through a hardness test, a tensile test, and optical microscopy. The hardness of the alloy containing 50% zirconium was approximatel…
We report a low-temperature loss anomaly in several oxidic perovskites such as ${\mathrm{KTaO}}_{3}$, ${\mathrm{KTaO}}_{3}$:Nb, ${\mathrm{SrTiO}}_{3}$, ${\mathrm{SrTiO}}_{3}$:Ca, ${\mathrm{PbTiO}}_{3}$:La, Cu, and ${\mathrm{BaTiO}}_{3}$:La. We show that this anomaly arises from a low-frequency dielectric relaxation. T…

The Journal of Phycology was founded in 1965 by the Phycological Society of America. All aspects of basic and applied research on algae are included to provide a common medium for the ecologist, physiologist, cell biologist, molecular biologist, morphologist, oceanographer, taxonomist, geneticist, and biochemist. The…
On an intermediate time scale, a molecular dynamics simulation of a two-dimensional (2D) liquid of soft disks exhibits dramatic structural and kinetic inhomogeneities. We introduce a local relaxation time (defined as the time required for a particle to first travel a distance r from its initial position) in order to p…
Cathodoluminescence (CL) spectroscopy has been used to investigate the irradiation-sensitive defect structure of ultrapure synthetic quartz at 295 and 80 K. CL emissions are identified with particular defect centers. Insight into the processes of defect formation and subsequent electromigration resulting from the trap…

The constant potential and constant current discharge techniques were used to determine the hydrogen diffusion coefficients in an electrode. The values obtained were , respectively. The advantages and disadvantages of these two techniques are discussed.
Abstract Organic photochromic systems represent a starting point for the elaboration of light‐triggered molecular switching devices. The novel bispyridinium and bispyridine compounds 1 2+ and 6 were synthesized as their uncyclized isomers from 3,5‐dibromo‐2‐methylthiophene in overall yields of 43 and 44%, respectively…
Abstract The elastic modulus E l of the crystalline regions of cellulose polymorphs in the direction parallel to the chain axis was measured by x‐ray diffraction. The E l values of cellulose I, II, III I , III II , and IV I were 138, 88, 87, 58, 75 GPa, respectively. This indicates that the skeletons of these polymorp…
