The synthesis and the structure of silicon carbide‐silicon nitride (SiC─Si 3 N 4 ) composite ultrafine particles have been studied. SiC─Si 3 N 4 composite ultrafine particles were prepared by irradiating a SiH 4 , C 2 H 4 , and NH 3 gas mixture with a CO 2 laser at atmospheric pressure. The composition of composite po…

Extractants employed for routine soil analysis vary from one laboratory to another. Lack of a universal soil extractant is a serious limitation for interpretation of analytical results from various laboratories on nutritional status of a given soil. This limitation can be overcome by developing functional relationship…
The formation of transparent conducting CdO films by chemical bath deposition is reported for the first time. These films exhibit an optical transmittance and electrical conductivity much higher than those CdO films prepared by other physical vapour deposition techniques. They exhibit an optical transmittance of more…
A fully automated magnetron-sputtering system for the deposition of complicated optical multilayer structures is described. The process control includes the real-time determination of the deposited layer thicknesses and adjustment of the remaining layer thicknesses to reoptimize the final performance of the multilayer…
The effects of alloying elements such as niobium, copper, chromium, molybdenum, and titanium in high-strength, low-alloy (HSLA) steels on hydrogen induced cracking (HIC) were investigated. The HIC test was performed to NACE TM-02-84 in BP (saturated H2S synthetic sea water) and NACE solutions. The test data were analy…
The use of naturally functionalized triglyceride oils in interpenetrating polymer networks (IPNs) is reviewed. An oil bearing either hydroxyl or epoxide functionality may be crosslinked to form a soft elastomer in the presence of another monomer or network to form an IPN, or in the presence of a linear polymer, to for…
The structures of 51 elemental liquids have been modelled from experimental diffraction data using the reverse Monte Carlo method. The structural trends across the periodic table are described in terms of three-body correlations and discussed in terms of the relative importance of two-body and many-body forces.
The dynamics and critical phenomena of the depinning transition in charge-density-wave (CDW) systems are explored, primarily through simulations of an automaton model that we have developed to characterize the essential features of the standard Fukuyama-Lee-Rice (FLR) treatment of CDW's. We first provide an overview o…
Vibration-level characteristics for Fe-doped lead-zirconate-titanate ceramic were studied using the constant current driving method. It was found that mechanical Q was markedly decreased with increasing vibration level, accompanying a lot of heat generation. The other electromechanical characteristics were slightly ch…
The kinetics of hexacelsian‐to‐celsian phase transformation in SrAl 2 Si 2 O 8 have been investigated. Phase‐pure hexacelsian was prepared by heat treatment of glass flakes at 990°C for 10 h. Hexacelsian flakes were isothermally heat‐treated at 1026°, 1050°, 1100°, 1152°, and 1200°C for various times. The amounts of m…
Abstract Eyring's theory of liquid viscosity was adapted to the special case of polymer molecules at a solid interface. The resulting model gives the slip velocity as a function of wall shear stress, temperature, pressure, work of adhesion and the molecular parameters of the polymer. The work of adhesion is related, o…
ABSTRACT The effect of the presence of a crystalline phase on the temperature dependence of segmental relaxation is examined. For both an aromatic and an aliphatic polyester, for polypropylene, and for poly-(dimethylsiloxane) (PDMS), it is demonstrated that crystallinity has an insignificant effect on the temperature…

Electrochemical impedance diagrams have been measured under controlled mass‐transport conditions for the transpassive anodic dissolution of , a stainless‐steel type alloy, in concentrated phosphoric‐sulfuric acid electrolytes under both polishing and nonpolishing conditions. The impedance diagrams consist of four part…
Following the ideas of Zachariasen and of Cooper, it is argued that the glass‐forming ability of a system can be rationalized in terms of the degrees of freedom available to form an infinitely large topologically disordered network composed of rigid structural units connected at vertices, edges, or faces. Expressions…

Abstract The binding energy and elastic constants of Li 2 S and Na 2 S are investigated at an initio all electron Hartree‐Fock level. The comparison between calculated and experimental value leads to satisfactory agreement for Li 2 S and a substantial difference in the Na 2 S case. The comparative evolution of the ela…
