The phase transitions in {N(CH 3 ) 4 } 2 XBr 4 (X: Zn, Co, Cu) were stuided by dielectric measurements. A phase transition which accompanied with a break on the dielectric constant vs temperature curve was found at 13.5°C and 13.8°C for {N(CH 3 ) 4 } 2 ZnBr 4 and {N(CH 3 ) 4 } 2 CoBr 4 , respectively.

Electrical conductivity of α quartz is ionic, the current being carried by alkali ions (M+) moving in channels parallel to the c axis. A study was made of conductivity σ of one natural and three synthetic crystals in order to better understand these ionic defects. ac measurements were made over a wide range of frequen…

The diffusion of rod-like molecules is studied in the case of high density. It is argued that when one goes to densities higher than those permitting rotational freedom for the rods, the diffusion of one rod will depend critically upon the cooperation of the others. A calculation of this effect using mean-field theory…

In Escherichia coli, quinolinic acid, a precursor of NAD+, is synthesized from L-aspartate and dihydroxyacetone phosphate. This synthesis requires two enzymes, a FAD-containing "B protein" and an "A protein." The B protein has been purified 500-fold from E. coli cells. The enzyme behaves as an L-aspartate oxidase. In…

Hydrogen adsorption on high-surface-area alkaline-earth oxides has been studied by i.r. spectroscopy at 300 and 78 K. In the former case heterolytic dissociation of H2 molecules produces hydride and hydroxy groups which are partially reversible upon evacuation. Low-temperature hydrogen adsorption appears to be undisso…

This investigation has been aimed at a better understanding of epitaxy; particularly, but not exclusively, in monolayers. The description has been facilitated by the introduction of a configuration space γ, spanned by the parameters relevant to epitaxy, namely, lattice parameters, misorientation, bonding, etc. The rig…

A magnetic state is observed below ∼ 3.5 K in the organic superconductor (TMTSF)2ClO4 just above the superconducting transition (Tc ∼ 1 K). This state is obtained by fast cooling with a rate of ∼ 25 K/min. and evidenced by 77Se and 1H-NMR intensity and relaxation measurements. The onset temperature is nearly field-ind…
