Many of the micaceous soils of the Indo-Gangetic alluvial plain of northwestern India are sodic and have clay-enriched textural B horizons. These soils sometimes lack identifiable clay skins. In order to determine the genesis of the textural B horizons of these soils, both with and without identifiable clay skins, one…
Application of polyaniline semiconductor films to potentiometric biosensor development provides certain advantages comparing with the known systems. Using self-doped polyaniline instead of common polymer as pH transducer the stable potentiometric response of 70 mV/pH was obtained. Taking as an example glucose biosenso…
The Schottky barrier formation between Bi and polycrystalline, ceramic ZnO has been studied with photoelectron spectroscopy (PES) under ultrahigh-vacuum conditions. This system is a simple model of a varistor compound. Evaporation of Bi on highly n-doped (Al) sintered ZnO surfaces, fractured in situ and held at room t…

Measurements of the dielectric permittivity are reported for a solid solution of antiferroelectric (betaine phosphate${)}_{0.15}$ and ferroelectric (betaine phosphite${)}_{0.85}$ at frequencies 20 Hz 1 MHz. The freezing phenomena in ${\mathrm{BP}}_{0.15}$${\mathrm{BPI}}_{0.85}$ reveal the characteristics of a transiti…

Abstract Polymer “brushes” are formed when long‐chain molecules are somehow attached by one end at an interface with a relatively small area per chain. Such adsorbed brushes in the presence of solvent may be used to modify surface properties, stabilize colloidal particles, etc. Strongly segregated block copolymer phas…
Abstract There exist important industrial applications, such as hoses or plastic windows, dealing with closely combining plasticized and rigid poly(vinyl chloride). Nevertheless, migration of plasticizer causes severe variation of the mechanical performance of the end‐products. This work comprises an effort to investi…
The paper presents the new method of mathematical treatment which allows to extract essential information about domain kinetics in polycrystal films from the traditional measurements of switching current. This information can not be obtained within the commonly used treatment. The method was verified by computer simul…
Densification and grain growth of porous alumina compacts during various high‐temperature processes were investigated. Experimental data were obtained for densification and grain growth of alumina powder during hot pressing. A set of constitutive equations was proposed based on the constitutive equations by Helle et a…

The stability of the \ensuremath{\gamma}' phase of the nickel-base alloy Nimonic PE16 under irradiation with ${\mathrm{Ni}}^{+}$ ions of 300-keV energy is studied by means of transmission electron microscopy. The disordering of the \ensuremath{\gamma}' phase could be followed as a function of fluence. The main finding…

CONTEXT: Liposomal encapsulation of drugs can potentially ameliorate toxicities and improve acute and chronic tolerance. The increased uptake of liposomes by colon adenocarcinoma cell lines may enable DaunoXome to circumvent the p-glycoprotein-mediated anthracycline resistance of colon cancer cells. PURPOSE: To determ…
Abstract In a previous study, we have investigated the structure, crystallization, and morphology of poly(aryl ether ketone ketone), PEKK, copolymers prepared from diphenyl ether (DPE), terephthalic acid (T), and isophthalic acid (I) with T/I ratios from 100/0 to 50/50. These materials were considered as having ‐DPE‐…
Abstract The roughness of the silver electrode was changed by variation of parameters of the oxidation–reduction procedure. The roughness size has been estimated qualitatively from the angle distribution of elastically scattered light. Quantitatively measurement of roughness by scanning electron microscopy and transmi…
