Abstract Rice hull silica and a rice hull carbon ash were evaluated as adsorbents for the soy oil bleaching process under commercial temperature and pressure conditions. Their performance in adsorbing pigment, phospholipid, free fatty acids, and peroxides was compared with that of a commercial bleaching clay and silic…
Abstract Morphology and oxygen permeability studies were carried out for blends of poly(ethylene terephthalate), PET, and poly(ethylene 2,6‐naphthalate), PEN, with poly(ethylene‐co‐vinyl alcohol), EVOH. PET/EVOH blends are seen as a possible substitute for poly(vinylidene chloride)‐coated PET packaging films. The effe…

A novel poly-beta-hydroxybutyrate (PHB) production system in which the expression and gene dosage of the Alcaligenes eutrophus pha biosynthetic operon were effectively regulated by cultivation temperature was constructed in Escherichia coli. The pha operon was fused to the negatively regulated tac promoter and cloned…

Abstract The voltammetric behavior in alkaline solution of a nickel‐based chemically modified electrode (Ni‐CME) prepared by oxidative electropolymerization of a nickel–tetraazaannulene complex (Ni II L) was investigated. After electrochemical deposition of the (Ni II L) n film in dichloromethane on a conducting subst…

This paper presents an overview of the practices employed by utilities and industries to combat the contamination problem with ceramic insulators. It emphasizes two popular methods, namely, coating insulators with greases and RTV (room temperature vulcanizing) silicone rubber coatings. The experience to date, applicat…
The paper reports on a study of the influence of the size of the particles of alumina trihydrate (ATH-Al/sub 2/O/sub 3/.3H/sub 2/O) filler on the life of room temperature vulcanised (RTV) silicone rubber coating in a salt-fog chamber. The particle sizes examined include 1.0, 4.5, 13, 17 and 75 /spl mu/m. The optimum s…
An automated apparatus has been developed to measure the transport of water vapor through coated and uncoated fabrics, fabric laminates, thin foams, and solid films under a variety of conditions. The apparatus is more convenient to use than the traditional test methods for textiles and clothing materials; it allows on…
Complete conductivity spectra of a lithium ion-conducting glass of composition B2O3-0·56Li2O-0·45LiBr have been taken at twelve temperatures, covering the frequency range from a few hertz to about 50THz. For the first time, a separation of the hopping and vibrational contributions to the spectra has been performed. Th…
Abstract New three-component organic conductors, (BEDT-TTF)2MM′(SCN)4 [M = K, Rb, Cs; M′ = Co, Zn, Cd], are prepared. The crystal structure analyses of α-ET2CsCo(SCN)4, ETZn(SCN)3, α-ET2RbZn(SCN)4, α-ET2CsZn(SCN)4, α-ETCd0.66(SCN)2, and ET2CsCd(SCN)4 are carried out. Most of salts have the α-type donor arrangement and…

Crack deflection in electrophoretically deposited Al 2 O 3 / TZ‐3Y (3 mol% Y 2 O 3 ‐stabilized tetragonal ZrO 2 ) lamellar composites with strong interfaces is described. The fracture behavior of, and crack paths in, these materials were evaluated using indentation and four‐point bend tests. The effects of residual an…

Abstract A novel design of a biodegradable carrier for drug delivery was established by constructing a supramolecular assembly of drugs and polymer backbones without any covalent bonds. A biodegradable polyrotaxane was synthesized in which α‐cyclodextrins (α‐CDs) as drug carriers were threaded onto poly(ethylene glyco…
