The present paper describes in a general way the most important of the advanced textile technologies which are oriented to the manufacturing of organic matrix composite materials, the paper presents their applications and the possibilities of future development. The use of these advanced weaving techniques allows the…
Various functionalized polythiophene films on electrode surfaces were produced by electropolymerization. Starting from 3-(2-hydroxyethyl)thiophene ( 1 ) different ether and ester derivatives were synthesized: 3-(2-(benzyloxy)ethyl)thiophene ( 2 ), 3-[2-((triphenylmethyl)oxy)ethyl]thiophene ( 3 ), 3-[2-((trimethylsilyl…
Li−LSX (Li−faujasite with Si/Al = 1), cubic at room temperature, is orthorhombic ( Fddd ) at 10 K. In the room-temperature Fd 3̄ phase, Li cations in the supercage are evenly distributed between 2-fold-coordinated sites III and III‘, in close agreement with the cation distribution in Na−X. The cubic−orthorhombic phase…
Although many thermal plasma processes have been developed for industrial applications, the wide acceptance as a manufacturing technology is prevented due to economical and competitive reasons, and/or reproducibility and reliability aspects. This paper is devoted to an assessment of the present knowledge in the follow…
This book, by one of the major contributors to dislocation theory, gives a highly detailed look, using planar examples, into the materials science aspects of many important physical processes associated with fracture.The compendium of references provided by this excellently researched book will be invaluable for the a…
Chiral nematic droplets of various radii $R$ and intrinsic pitch $P$ with parallel boundary conditions have been observed using a polarizing microscope. The visual appearances of the droplets have been compared with computer simulations from model director fields. It is found that the director configuration depends st…
The first- and second-order Raman phonon spectra of CsPbCl3 were measured in phase IV using Raman and resonance-Raman scattering. Twelve Raman active phonons were resolved at 32, 35.5, 42, 52, 72, 90, 110, 115, 121, 189, 200.5, and 375 cm−1 and correlated to the phonon spectrum of CsPbCl3 in phase I. The highest frequ…
Noncentrosymmetric crystals of photochromic N-salicylidene-4-bromoaniline are obtained and studied for their second-order nonlinear optical properties. Second harmonic light is generated and can be seen by the naked eye. Moreover, photochromism in the bulk state yields totally reversible photoswitching of the second h…
The structure of the nearly commensurate phase of $1T\ensuremath{-}{\mathrm{TaS}}_{2}$ ${(1T}_{2}\ensuremath{-}{\mathrm{TaS}}_{2})$ has been refined in $(3+2)$-dimensional superspace against single-crystal x-ray-diffraction data collected at 300 K. The intensities of main reflections and satellites up to sixth order w…
Nonlinear localized excitations in one-dimensional diatomic lattices with cubic and quartic nonlinearity are considered analytically by a quasi-discreteness approach. The criteria for the occurence of asymmetric gap solitons (with vibrating frequency lying in the gap of phonon bands) and small-amplitude, asymmetric in…
Diatoms have evolved a multitude of morphologies, including highly elongated cells and cell chains. Elongation and chain formation have many possible functions, such as grazing protection or effects on sinking. Here, a model of diffusive and advective nutrient transport is used to predict impacts of cell shape and cha…
Monazite-structure orthophosphates, including ${\mathrm{LaPO}}_{4},$ ${\mathrm{PrPO}}_{4},$ ${\mathrm{NdPO}}_{4},$ ${\mathrm{SmPO}}_{4},$ ${\mathrm{EuPO}}_{4},$ ${\mathrm{GdPO}}_{4},$ and natural monazite, and their zircon-structure analogs, including ${\mathrm{ScPO}}_{4},$ ${\mathrm{YPO}}_{4},$ ${\mathrm{TbPO}}_{4},$…
Two-dimensional heteronuclear (1H-15N) nuclear magnetic relaxation studies of dihydrofolate reductase (DHFR) from Escherichia coli have demonstrated that glycine-121 which is 19 A from the catalytic center of the enzyme has large-amplitude backbone motions on the nanosecond time scale [Epstein, D. M., Benkovic, S. J.,…
The distinction between point and line resolution in transmission electron microscopy (TEM) arises because an ability to image sub-0.2 nm fringes is a necessary, but not a sufficient, condition for imaging individual atoms. In scanned tip microscopy, as in TEM, empirical data on instrument response should precede asse…
A novel process to produce a nanochannel comprised of a void in a polymer matrix is reported. The processing involves a selective degradation of one of the bicontinuous microdomain phases of microphase-separated block copolymers to create a continuous, tortuous hole having a diameter of nanometer scale (nanochannel) a…
RATIONALE AND OBJECTIVES: The authors evaluate MS-325, a new albumin-targeted magnetic resonance imaging (MRI) contrast agent, for its pharmacokinetics, biodistribution, and elimination characteristics in multiple animal species. METHODS: Studies were performed in rats, rabbits, and nonhuman primates at intravenous do…
RATIONALE AND OBJECTIVES: The authors developed a new method for delivering contrast agents to tumors and tumor cells. Gadolinium complexes of folate-conjugated dendrimer-chelates increased the longitudinal relaxation rate of tumor cells expressing the high-affinity folate receptor, hFR. The coupling of folate to poly…
High molecular weight poly(butylene succinate- co -ethylene succinate)s, P(BS- co -ES)s, were obtained from succinic acid, 1,4-butanediol, and/or ethylene glycol through a polycondensation process. Enzymatic hydrolysis of hot-pressed copolyester films was carried out by utilizing lipases derived from a wide variety of…
