Influence of chlorine on the surface area and morphology of TiO2
(Elsevier, 1985)
Changes in BET surface area and morphology of TiO2 (anatase) were studied as a function of temperature and level of chlorine contamination. The obj
Creep, Strength and Moisture Absorption of Adhesive Bonded FRP Joints
(Sage Publications, 1985)
The effects of the environment on adhesive bonded single lap joints formed using XMC-3 and SMC-R50 composites were investigated. Tests were performed at temperatures of 23C and 93C with test coupons immersed in air, water, ...
CO hydrogenation catalyzed by alumina-supported osmium: Particle size effects
(Elsevier, 1985-10)
Alumina-supported catalysts were prepared by conventional aqueous impregnation with [H2OsCl6] and by reaction of organoosmium clusters {[Os3(CO)12], [H4Os4(CO)12], and [Os6(CO)18]} with the support. The catalysts were ...
Metal dispersion of bimetallic catalysts via stepwise chemisorption and surface titration : I. Ru---Au/SiO2
(Elsevier, 1985-09)
A stepwise chemisorption and titration procedure involving H2 and O2 as adsorbates is used to measure the dispersion of the individual metal components in bimetallic Ru---Au/SiO2 catalysts. The experimental approach is ...
The maximum melting temperatures in strain-crystallized van der waals networks
(Steinkopff-Verlag; Steinkopff ; Springer Science+Business Media, 1985-04)
A theory of strain-crystallization of random networks comprised of stereoregular chains is developed. The crosslinks are assumed to be expelled from crystal cores. For this reason, the rubber is considered to be represented ...
A novel catalytic reactor system for transient response and its use in CO oxidation on Pd/Al2O3
(Elsevier, 1985-08)
In this paper we describe a computer-controlled reactor system capable of imposing any concentration-forcing function on the input. Combination of a monolithic support with a fast-scan Fourier Transform Infrared (FTIR) ...
A thermodynamic and kinetic basis for understanding chromium depletion in Ni-Cr-Fe alloys
(Elsevier, 1985-05)
Thermodynamic and kinetic models are constructed to describe the development of the chromium depleted zone in Ni-Cr-Fe alloys heated in the range 773-1173 K. The models are interactive and constitute a computer program ...
Microcalorimetric studies of the heats of solution of bovine myelin basic protein
(Elsevier, 1985-10-04)
Heats of solution for myelin basic protein have been determined using microcalorimetry. All aqueous systems studies yielded negative heats of solution; in contrast, trifluoroethanol produced a small positive heat of solution, ...
A convenient synthesis of -(5'-deoxy-5'-adenosyl)- (+/-) -2-methylhomocysteine
(Elsevier, 1985)
The synthesis of -(5'-deoxy-5'-adenosyl)-+-2-methylhomocysteine in two steps from +--2-methylmethionine is described.
