Porphyrins appended with crown ether, benzo-15-crown-5, at the methine positions have been synthesized and \ncharacterized. The fully and partially substituted porphyrins and their metallo (Co, Cu, and Zn) derivatives describe one or more ether cavities in the periphery that are capable of recognizing spherical ca…

The filling of thin-walled glass capillaries is tedious and time consuming especially when the powder tends to agglomerate due to extremely fine grinding (<10 t~m) in a micronizing mill. While special devices have been designed for loading capillaries in a dry box (Larsen & Leddy, 1958; Lange & Haendler, 1972), a tech…

Abstract The human central nervous system pharmacology of cis -diamminedichloroplatinum (CDDP) was studied, and trials were initiated of CDDP as a radiosensitizer in the treatment of malignant primary brain tumors. Samples were assayed for platinum using X-ray-dispersive fluorescence spectrometry. Platinum was barely…

Since the serine proteases form the most thoroughly understood family of enzymes, it is of some interest to consider what the two principal physical techniques of studying enzymes, crystallography and nuclear magnetic resonance (NMR), have told us about the details of their enzymatic mechanism. Due to limitations of s…

Abstract The chemisorption of CO on Co(10&1macr;0) has been investigated by LEED, UPS, EELS, Auger and sp measurements. CO is molecularly adsorbed between 100 and 420 K. This can be deduced from UP spectra, EEL spectra and the reversibility of the sp and the LEED results. The initial isosteric heat of adsorption h…

Electrode films of lanthanide diphthalocyanines undergo a series of reversible color changes that make them potentially very attractive as flat-panel color display materials. Research on these compounds has revealed a complex scheme of electrode processes that is not yet fully characterized. The solid organic phases w…

The anodic corrosion of gold has been studied in concentrated chloride solutions as a function of chloride concentration and p H. Results are discussed in terms of five potential regions: active, prepassive, active‐to‐passive transition, passive, and transpassive. The existence of with a dissociation constant of the o…

This paper postulates a physical model of electric aging and breakdown of polymeric insulated high voltage cables and substantiates this model with results of tests. In accordance with the model, scission of molecular chains and formation of craters at discharging voids are responsible for the electric aging and volta…

The viscosity of a soda-lime silica glass was measured at high strain rates. The data show non-Newtonian viscous flow in this inorganic oxide glass with the viscosity values below the expected Newtonian value. Following the imposition of large, steady strain rates, the observed stress increases with time to a maximum…

The behavior of unstable regions in the composition plane for III–V quaternary solid solutions made from among Al, Ga, In, P, As and Sb is analyzed, based on the strictly regular solution approximation for solid solutions. Temperature dependences of spinodal isotherms at 400–1000°C show that unstable regions cover a w…
