Potentiostatic cathodic electrodeposition of ZnTe was investigated from the viewpoint of the effect of pH on the deposits' composition and crystallinity using citric acidic electrolytic baths, in which Zn(II) and Te(IV) species were dissolved to form ZnH2Cit+, ZnHCit, ZnCit−, Zn(Cit)24− and HTeO2+, HTeO3−, respectivel…
Efficient hydrogen evolution from decalin by heating at 210°C and cooling at 5°C was attempted in a batch-wise reactor by the use of “superheated liquid-film-type catalysis”. When the carbon-supported metal catalyst 0.75 g was immersed with decalin 3.0 ml under a reactive distillation conditions, a liquid-film state w…
The first bioinorganic vanadocene(IV) complexes of α-amino acids ([Cp 2 V(aa)]Cl, Cp = η 5 -C 5 H 5 , aa = glycine, L-alanine, L-valine) were prepared by reaction of vanadocene dichloride ([Cp 2 VCl 2 ]) and α-amino acids in aqueous methanol. Analogous cationic complexes with PF 6 - counterions were obtained by metath…
The thresholdless, hysteresis-free V-shape electrooptical switching in surface stabilized ferroelectric liquid crystal (FLC) cells has been modeled and the results compared with experimental data. High frequency V-shape switching (at f>100 Hz) was experimentally demonstrated and simulated numerically. The key role of…
Uniformly porous composites with 3‐D network structure (UPC‐3D) have been recently developed via a pyrolytic reactive sintering process, which takes advantage of the evolved CO 2 gas from a decomposing carbonate source (e.g., dolomite, CaMg(CO 3 ) 2 ) and does not require any additional pore‐forming agent nor long‐tim…
This paper is in four parts. The first is related to general considerations and experimental analyses, and each of the others is related to different approaches to theoretical analyses of the mechanical behaviour of weft-knitted fabrics and weft-knitted reinforced composites made of glass fibre. The objective is to fi…
Abstract Although glass corrosion resistance has been tested with laboratory methods for decades, investigators are now just beginning to understand the reaction phenomena at or close to saturation with respect to the rate-limiting phase(s). Near saturation, the phenomena that govern element release rates include alka…
Stratified systems comprising an inhibitor-doped layer-by-layer (LBL) clay-polyelectrolyte overcoated with a dense organically-modified silicate (Ormosil) are investigated as corrosion protectors for aluminium. As separate coatings, neither the LBL nor Ormosil films were found to provide adequate corrosion protection…
Periploca sepium is used in Chinese crude drugs and widely employed as a tonic. The volatiles obtained by steam distillation (yield, 0.10%) included 4-methoxysalicylaldehyde (87.8%), furfural (3.13%), and lavender lactone (0.77%) as the major components.
An attempt was made to fabricate composite material of an Al alloy matrix reinforced by TiNi shape memory fiber using a hot-press method and to investigate its microstructures and mechanical properties. The analysis of SEM and EDS showed that the composite material had good interface bonding. The stress-strain behavio…
Abstract Photoinduced recoordination of Ca 2+ complexes of photochromic azacrown ethers is studied by the density functional method using model arylazacrown ethers and a real azacrown‐containing styryl dye. Two types of previously found conformations of the crown ether–calcium complexes, axial and equatorial, are stud…
We prove convergence towards an equilibrium state for any globally defined solution for a conserved phase field model. A generalized version of the Lojasiewicz-Simon theorem is used.
We demonstrate the possibility of a selective nonequilibrium cap opening of carbon nanotubes as a response to femtosecond laser excitation. By performing molecular dynamics simulations based on a microscopic electronic model we show that the laser-induced ultrafast structural changes differ dramatically from the therm…
We have measured the thermoelectric power of individual single walled carbon nanotubes (SWNTs), using a novel mesoscopic device. Microscopic heaters and temperature sensors were fabricated adjacent to chemical vapor deposition grown SWNTs on a silicon oxide/silicon substrate. Temperature gradients greater than 0.1 K/μ…
In an attempt to elucidate the effect of mixing in high‐shear regimens on the extent of enzymatic hydrolysis of cellulosic substrates, cellulose was hydrolyzed using a commercial cellulase preparation at various enzyme concentrations and by three agitation regimens. The activity of cellulase decreased with increasing…
Perovskite-type BaTiO3/SrTiO3 (BTO/STO) artificial superlattices were fabricated by molecular beam epitaxy process and their dielectric properties and refractive indices were measured. A large leakage current was observed in the films on Nb-doped STO substrate. Dielectric permittivity was therefore measured using plan…
A chemical method to coat submicron silica particles with nanocrystalline zinc sulfide is described. The ZnS nanocoating was obtained by the thermalysis of zinc diethyldithiocarbamate in the presence of morphologically well defined silica particles. The powders obtained were isolated and were characterized by UV/visib…
Experimental investigations of thermal microscopy, low frequency dielectric relaxation, spontaneous polarization P s (T), optical tilt angle θ(T) and response times τ s (T) are carried out in a fluorinated ferroelectric liquid crystal, N125F2(R*) exhibiting smectic-A and smectic-C* phases. Dielectric loss in the smect…
ArF resist-pattern shrinkage in critical-dimension scanning electron microscopy (CD-SEM) measurement is investigated, and its mechanism is discussed. In CD-SEM irradiation damage in the resist detected by Fourier transform infrared (FTIR) spectroscopy, we propose that C=O units of pendant polymer chains decompose COOH…
OBJECTIVES: Aim of this study was to evaluate the clinical benefit and the toxicity of pegylated liposomal doxorubicin. PATIENTS AND METHODS: Patients with metastatic breast cancer (n = 30) who failed a prior chemotherapy regimen for metastatic disease received 45 mg/m2 pegylated liposomal doxorubicin (PLD) every 4 we…
