<div class="htmlview paragraph">Twenty-two physical and chemical properties of a typical automatic transmission fluid were determined. In most cases the properties were determined over a range of temperatures. In general, air solubility, volumetric thermal expansion, and specific heat increase with increasing te…

The effective thermal conductivity of binary dispersed composites prepared from mixed and compacted powders of AgCl and low-density polyethylene was measured over the entire range of volume fraction at temperatures in the range 100–330 K together with pressures up to 1.75 GPa. Measurements were made using the transien…

Abstract A simple method for the consolidation of all of the conventional cushion curves for a particular material into a single relationship is discussed. The method requires only one of the usual cushion curves for an arbitrary drop height and cushion thickness to deduce the dynamic stress‐strain curve for the mater…

Abstract The thermal annealing properties of (H3O4)0 centres in single crystal SiO2 were studies by means of electron spin resonance (ESR). The data indicate that these centres take part in the TL process at 110 oC in this material. The mechanism suggested for this TL signal is the thermal release of electrons from (G…

The possible use of Fourier transform infrared reflection‐absorption spectroscopy (FT‐IRAS) and Raman spectroscopy for surface studies of thin (<10 nm) corrosion products on Cu has been explored. Cu samples were exposed to 75% relative humidity and 25°C in flowing air, with additions of 0.25 ppm of SO 2 and NO 2 . X‐r…

Abstract The efficiency of α, I pair creation at exciton decay is high at 4.2 K for KCl, KBr, and RbBr crystals for which H centers are oriented along 〈110〉. The efficiency of α, I pair creation by VUV‐irradiation at 4.2 K is extremely low for NaCl crystals for which H centers are oriented along 〈111〉. The process of…

Abstract A thermodynamic framework for the analysis of gas sorption in glassy polymers is established in the limit of low sorption levels. The results represent an extension of the Flory‐Huggins theory to materials with nonzero internal energy changes due to deformation; the Flory‐Huggins theory is recovered in the li…

Linearly polarized laser light is scattered from an oscillating, acoustically levitated bubble, and the scattered intensity is measured with a suitable photodetector. The output photodetector current is converted into a voltage and digitized. For spherical bubbles, the scattered intensity I(rel)(R,theta,t) as a functi…

CenA from Cellulomonas fimi is a beta-1,4-endoglucanase that binds tightly to cellulose. X-ray-scattering analyses show that the enzyme is tadpole-shaped: the previously identified catalytic and cellulose-binding domains comprise the head and tail respectively. It appears that this structural and functional organizati…

In this paper, we study the thermodynamic properties of dense plasmas considered as high-temperature liquid metals. The problems that have to be solved are the following: (1) calculation of the ``average'' electron-density profile around an ion in the plasma, (2) determination of a self-consistent average ionization o…

Abstract A soluble aromatic poly (amic acid) film was converted to a soluble polyimide by staging at 25°C intervals to 325°C and characterized at each interval by several analytical methods. The behavior observed was consistent with an interpretation that a reduction occurred in molecular weight of the poly (amic acid…
