Use of Radioactive Chromium Oxide in Digestibility Determinations

Measurement of gastrointestinal transit using radioactive chromium.

Association of radioactive chromium with various components of hemoglobin.

IN 1950, Gray and Sterling1 investigated the distribution of radioactivity in washed human erythrocytes after incubation of whole blood with radioactive sodium chromate ( Na2Cr51O4 ) . They found that over 90 per cent of the isotope was bound to the globin of hemoglobin and the remainder was associated with the red cell stroma. The heterogeneity of normal human hemoglobin2’3 and the existence o...

Pulsed plasma deposition of chromium oxide/chromium-cermet coatings

A novel radio frequency magnetron sputtering method for the deposition of composite films which consist of chromium oxide and chromium ~Cr2O3/Cr-cermet! is presented. As an extension to conventional reactive sputtering of a Cr target in an argon and oxygen atmosphere the oxygen flow into the process chamber is switched periodically on and off. This leads to an oscillating oxygen partial pressur...

Bistable memory effect in chromium oxide junctions

Magnetotransport properties of granular CrO2 /Cr2O3 films made of CrO2 crystals covered by 12 nm native insulating Cr2O3 are presented. Electrical properties of a limited number of grains measured in series and parallel (10 to 15 grains) reveal intergrain tunneling characteristics. At lowest temperatures, a well pronounced zero bias anomaly indicates that impurities in the junctions block the e...
