The primary crystalline phase developed in glass-ceramics in the system PbO-BaO-TiO2-B2O3 was investigated. X-ray diffraction and dilatometry were used to identify the primary phase as essentially pure PbTiO3. Peak shifts observed in X-ray diffraction patterns resulted from lattice strain due to crystal clamping, and…
Abstract Temperature dependences of isochoric heat capacity, temperatures and enthalpies of physical transitions for polyglycolide, poly(β‐propiolactone), poly(γ‐butyrolactone), poly(λ‐valerolactone), poly(ε‐caprolactone), polyundecanolactone, polytridecanolactone, and polypentadecanolactone were studied between 13,8…

Potentiostatic experiments in 0.5 N NaCl at − 0.25 V SHE show that the kinetics of dealloying of copper base binary alloys fall in the order Cu ‐ Al > Cu ‐ Mn > Cu ‐ Zn > Cu ‐ Ni For the solutes Al and Zn, the kinetics of dealloying may be expressed by the relationship Log S e = KC s where S e is the excess solute dis…
Abstract Great attention has been paid to the toughening of isotactic polypropylene (PP) in recent years in order to make full use of this plastic. This paper presents the results of our study on the compatibility of PP with ethylene‐propylene‐diene rubber (EPT), polybutadiene rubber (PB) or styrene‐butadiene rubber (…

An examination has been made of the mechanism of breakdown of passive films on iron in borate buffer solution caused by chloride ions. Various electrochemical kinetic criteria were measured. XPS, SIMS, and ISS studies were made of the systems used in the electrochemical work. The rate of breakdown was found to be prop…
Many different nonsilica-based fiber materials are presently being examined as possible candidates for use in extremely low loss fibers for infrared communications. One useful figure of merit in estimating fiber potential for low absorption is the total intrinsic scattering loss at the minimum dispersion wavelength. I…
Abstract Samples of isotactic polypropylene in the α form may have different degrees of order in the up and down positioning of the chains. By suitable programming of the crystallization history of unoriented samples it is possible to show, from DSC and WAXS data, that a strict correlation exists between the melting b…
Electroactive and electrochromic films of electropolymerized polyazulene and polythiophene have been found to be surprisingly insensitive to common solvents and temperature. As electrodes in all‐organic batteries these thin polymeric films allow current densities of 2 mA/cm 2 at open‐circuit voltages of 2.3V. The elec…
Abstract The new industrial strategy in the polymer field requires the transformation of plastic “commodities” into “specialties”. From this point of view, polypropylene (PP) plays an important role both for its intrinsic properties such as high melting temperature, low density, high chemical inertness and for its cap…

Abstract Using Garfield, Washington, nontronite as the model mineral system, methods and apparatus were developed to prepare reduced suspensions in citrate-bicarbonate-dithionite (CBD) solution. These techniques were effective in removing excess, undesired solutes from reduced suspensions while maintaining a high Fe 2…

Abstract The mechanical properties of a variety of immiscible binary blends, with and without third component polymeric compatibilizers, are reviewed and qualitatively related to the degree of adhesion between blend components as determined by lap shear testing. Generally, blends comprised of components which adhere w…
Abstract Results of an investigation on the morphology, the crystallization and the thermal behavior of several binary crystallizable blends are reported. The composition, molecular mass and crystallization conditions strongly influence the crystallization and the thermal behavior as well as the overall morphology of…
SUMMARY Samples of six soils were incubated at 60°C for 24 h with several levels of either calcium carbonate or hydrochloric acid. Phosphate sorption was then measured on sub‐samples of the treated soils over 24 h at 25°C. In one set of measurements on all soils, 0.01 M calcium chloride was used as the background elec…
