A study has been made of the morphogenetic properties of anterior and posterior skin from the lower forelimb of the axolotl. The basic experiment consisted of a graft of a half cuff of skin from a donor to a host limb followed by a 2-week healing period, amputation through the graft, and a study of the resulting regen…
Thermal stresses in chemical vapor deposited (CVD) vitreous silicate and phosphosilicate glass (PSG) films on Si substrates are measured in situ from room temperature (RT) to 900 °C. As-deposited films grown at one atmospheric (APCVD) and lower pressures (LPCVD) are found to be inherently under a tensile and compressi…

The corrosion of mild steel in kraft chemical pulping equipment has been investigated by laboratory electrochemical testing in relevant caustic solutions. Potentiostatic polarization curves were obtained in alkaline electrolytes with additions of sulfur containing compounds known to exist in process liquors. By observ…

Physical CO solubilities and total O 2 solubilities (as chemically formed O 2 − and O 2 = ions) have been determined for a comparatively wide range of carbonate melt compositions, and some restricted data on nitrogen and CO 2 solubilities have also been obtained. In general, the Uhlig‐Blander equation in its simple fo…

Arrhenius plots are useful in predicting long-term use temperatures of organic materials and in choosing parameters for accelerated aging. For materials and components without established Arrhenius curves, a conservative value for the slope of the curve (which is also a measure of the activation energy of degradation)…

Magnetoelectric experiments provide information on spin configurations, critical indices and microscopic ionic interactions. The basic theory of the magnetoelectric effect in antiferromagnets is rederived in this article and extended to situations in which there is an external magnetic field including the spin-flop ph…

Abstract Infrared (IR) spectroscopy was used to study molecular deformation processes in polymers as a function of stress, strain, time and temperature. Stress‐induced frequency shifts were found to depend on temperature and morphology. Deformation of viscoelastic polypropylene was examined in terms of time dependent…
Abstract— Two examples of a new class of compounds, polyenes covalently linked to meso‐ tetraarylporphyrins, have been prepared. Optical studies revealed that energy transfer from a 26 π electron polyene moiety to the porphyrin was zero, whereas energy transfer efficiency from a polyene containing 18 π electrons was ˜…
The fluorescence excitation spectrum of free base phthalocyanine was observed in a supersonic free jet. The spectrum was very intense, and the cooling provided by the supersonic expansion produced a very well-resolved spectrum showing extensive vibrational structure. This is the first time that vibrational structure h…
For many years, study of the defect state of oxide crystals was overshadowed by activity in the alkali halides. However, during the last decade, work on oxides has emerged as an important field of study in its. own right. This burgeoning of interest came about for many reasons. First the properties of defects in the a…
A new type of highly stabilized GaAs FET oscillator using a dielectric resonator and a stabilization resistor in the feedback circuit has been developed. The oscillator fabricated with a microwave integrated circuit has a high external quality factor Q/sub ex/ for more than1000 with no hysteresis phenomena. The microw…
