Abstract Injection molded short glass fiber reinforced poly(butylene terephthalate) was subjected to hygrothermal aging at two different relative humidities—81.2% and 100% RH. A single free phase model of diffusion has been used to analyze the data obtained from the kinetics of moisture absorption study. The diffusion…

Wood fiber reinforced cement composites provide the highest performance‐to‐cost ratio among fibrous cement composites being considered for the replacement of asbestos cement. Fairly strong and stiff wood fibers are particularly suited for the reinforcement of thin‐sheet cement products. There is, however, concern rega…
In the presence of a fluorine mineralizer, highly aggregated, <5 μm α‐Al 2 O 3 platelet particles form by vapor transport during the thermal transformation of γ‐alumina. Platelet aggregation was determined to occur by platelet inter‐growth and by edge nucleation on primary α‐Al 2 0 3 platelets. The addition of 10 1…

The induced polarization and longitudinal strain behavior of lanthanum‐ and titanium‐modified antiferroelectric lead zirconate ceramics were measured as functions of electric field as high as 30 kV/mrn (300 kV/cm). Two field‐induced phase transitions were observed, both in polarization and strain. Polarization and str…

The corrosion mechanism of copper at 373 and 300 K in the presence of submicron particle deposits has been investigated. Several in situ techniques have been used to monitor the corrosion process in real time. At and above the critical relative humidity of , dissolution of Cu is followed by formation of , oxidation of…

The connection between the Bremmer (reflection) series method and the R-matrix propagation method for modeling diffraction gratings is revealed. Both methods have been previously demonstrated to be immune from the problem of loss of significant digits caused by the growing and decaying exponential functions. It is mat…

Dielectric properties based on tautomerization in 9-hydroxyphenalenone derivatives were examined. While the 5-methyl derivative 2 exhibits an antiferroelectric transition at 41 K, such a phase transition was not observed in 5-bromo derivative 3 down to 4.2 K. Suppression of the phase transition in the latter may be in…
Strong interest has been generated in recent years regarding the modification of polyolefins to be functionalized or engineered for new materials with superior properties. Functional and engineered polyolefins are becoming more and more commercially important and expanding their applications as demonstrated by the sci…
Some velocity field results from the Surface Tension Driven Convection Experiment (STDCE) that was conducted aboard the USML-1 Spacelab in 1992 are reported. 10 cSt silicone oil was placed in an open circular container (10 cm wide×5 cm deep) and heated either by a cylindrical heater (1.11 cm diam) placed along the cen…
The design of narrow bandgap polymers remains a major challenge in the field of organic conductors. An alternative scheme is proposed for reducing the bandgap, namely the construction of a one‐dimensional graphitelike chain. Terthienyl frozen in a fully planar syn conformation is used as a simplified model compound fo…
