Powders of modified chromium dioxide produced by the hydrothermal method were studied using 57Fe Mossbauer spectroscopy at a temperature of 298 K. The content of the modifier, i.e., 57Fe compound, was varied from 2 to 10 mmol/mol Cr at a Sb content o

The effect the shape anisotropy of particles of compacted CrO2 powders have on tunnel magnetoresistance is investigated in the temperature range of 4.2–20 K. Measurements are made at different orientations of the magnetic field relative to the samp

The resistive, magnetoresistive and magnetic properties of cold-pressed CrO2, powder prepared by hydrothermal synthesis from chromic anhydride have been studied. The powder particles (with a mean diameter of about 120 nm) were nearly spherical. The p

Molecular alterations in the mismatch repair system suggest that this mechanism may be important in the evolution of cutaneous melanoma. Our current study evaluated the expression of two mismatch repair proteins, hMLH1 and hMSH2, in dysplastic nevi (

This paper describes a new mission concept for the Space Infrared Telescope Facility (SIRTF). In this new concept, SIRTF is launched with just enough energy to escape Earth's gravity. This trajectory is equivalent to a 1 astronomical unit (AU) solar

The Space Infrared Telescope Facility (SIRTF) is the fourth in NASA's series of Great Observatories. It will feature a one-meter class cryogenically cooled telescope. It is planned for a NASA fiscal start for the development phase in 1994 with a laun

In a previous article [J. Chem. Phys. 76, 429 (1982)] we presented a model for collisional energy transfer between dark (A′ 1Π, a 3Π) and radiating (A 1Σ+) excited electronic states of the alkaline earth oxides. The inelastic transitions result
