Reaction between Iron and Sulfur Compound with S-35 as a Tracer

Permselectivity of the glomerular wall examined with iron compound tracer.

Rat kidney endothelial cell morphology was examined after introducing iron colloid particles of positive or negative charge to investigate the relationship between the electric charge and permeation through the glomerular capillary. The kidneys were first perfused with Hanks’ solution through the renal arteries and then with iron colloid particles of positive or negative charge. The iron colloi...

Using sulfur as a tracer of outdoor fine particulate matter.

Six homes in the metropolitan Boston area were sampled between 6 and 12 consecutive days for indoor and outdoor particle volume and mass concentrations, particle elemental concentrations, and air exchange rates (AERs). Indoor/outdoor (I/O) ratios of nighttime (i.e., particle nonindoor source periods) sulfur, PM2.5 and the specific particle size intervals were used to provide estimates of the ef...

Sulfur-35 as a Mutagenic Agent in Neurospora.

Iron as a Tracer in Galaxy Clusters and Groups

Available X-ray data are collected and organized concerning the iron and gas content of galaxy clusters and groups, together with the optical luminosity, mass and iron abundance of cluster galaxies. Moving from such a restricted number of cluster parameters several astrophysical inferences are drawn. These include the evidence for rich clusters having evolved without much baryon exchange with t...

Synthesis of calcium carbide-derived carbon by mechanochemical reaction of calcium carbide with sulfur, iron sulfide and zinc oxide

In the present work, we report a novel design and preparation for the mechanochemical synthesis of calcium carbide-derived carbon (CaC2-CDC) at ambient temperature. Thermodynamic calculations confirmed the possibility of calcium carbide-derived carbon formation by the reaction of calcium carbide with sulfur, iron sulfide and zinc oxide at ambient temperature. The CDCs were synthesized by the ba...
