The mechanical behavior of three CVT‐processed 2D woven SiC/BN/SiC composite materials with different initial BN interphase thicknesses has been investigated by means of tensile and impact tests. The results have established the efficiency of a BN interphase in promoting a nonlinear/non–catastrophic tensile behavior a…
In order to gain insight into the degradation mechanisms associated with ferroelectric thin films, such as fatigue and imprint, an understanding of the defect chemistry and transport properties of the material is needed. In this study several complimentary techniques have been used to either measure or calculate indir…

Abstract In this short review, some important phenomena often observed in blends of thermotropic liquid crystalline and thermoplastic polymers are described. Their outstanding physical properties will probably lead to applications as in situ composites. LCP of low concentration in the thermoplastic matrix can be used…

Nanoparticles /spl gamma/-Fe/sub 2/O/sub 3/ were prepared in silica matrix by the sol-gel process. Conventional acid hydrolysis and polycondensation of tetraethyl orthosilicate (TEOS) were used for the preparation of porous silica matrix. Iron(III) nitrate was homogeneously dissolved in the initial TEOS solution. Afte…

β‐Barium borate (BBO) surface crystallized glass composites were prepared for a glass of composition 40BaO·15Tio 2 –45B 2 O 3 (in mol%). Enhanced nucleation was attained by ultrasonic surface modification with an aqueous suspension of BBO particles, resulting in dense BBO thin films on the glass surfaces. Second harmo…
We have proposed a new optical method for measuring the twist angle of twisted nematic cells, and the method has been applied to obtain the azimuthal anchoring energy for a nematic liquid crystal. The method is based on a modulation in the polarization state of an incident probing laser beam to the sample cells, and t…

Up to 3 moles of Li are inserted per mole of V 2 O 5 · 0.5 H 2 O xerogel (XRG), as shown by concurrent charge and mass measurements with a quartz crystal microbalance. Further, it is demonstrated that only Li + ions are intercalated from the electrolyte, without cointercalation by other species in LiClO 4 solutions in…
The photoexcited triplet states of the nonplanar porphyrins, free base and zinc 2,3,7,8,12,13,17,18-octaethyl-5,10,15,20-tetraphenylporphyrins (OETPPs), were examined by laser excitation-time resolved EPR spectroscopy. Measurements were carried out at low temperatures in glassy matrices, and over a wide temperature ra…
Heteroepitaxial growth of SrTiO 3 (STO) films with and without buffer layers on Si(100) and (111) substrates has been conducted by a focused electron beam evaporation method. It has been found that thin metallic layers such as Ti and Sr are effective for improving the quality of overgrown STO films, which is probably…
<div class="htmlview paragraph">The modeling of transient phenomena occurring inside an automotive 3-way catalytic converter poses a significant challenge to the emissions control engineer. Since the significant progress that has been observed with steady-state models cannot be directly exploited in this directi…
In this paper, we describe the effects of electrode materials on the leakage current of Ta 2 O 5 films, and show optimum electrode materials for high- and low-temperature processes. The leakage current depends on the electrode material and varies with the annealing temperature. The leakage current is mainly determined…
Effects of lithium bromide (LiBr) concentration, pH, temperature, exposure time, and the action of some inhibitors on corrosion of several carbon (C) steels, stainless steels (SS), and a titanium (Ti) alloy were studied. Corrosion rates were determined by the polarization resistance method and compared to rates determ…
Abstract Superior impact properties were obtained when maleic anhydride grafted styrene ethylene/butylene styrene block copolymer (SEBS‐g‐MAH) was used as a compatibilizer in blends of polyamide 6 (PA 6) and isotactic polypropylene (PP), where polyamide was the majority phase and polypropylene the minority phase. The…

Three types of artificial skin containing keratinocytic components were prepared and tested for comparison. Keratinocytes were cultured on the artificial skin dermis (collagen sponge) by the air-liquid interface culture method. In order to create continuous keratinocytic layers on the artificial skin dermis, pores of…
