Thermal Plasma Synthesis of Ultrafine Iron Particles

Abstraet--Ultrafine iron powder was synthesized in an atmospheric-pressure radio-frequency plasma reactor by injecting relatively course iron powder into the plasma, where it evaporated. The renucleated iron particles were characterized by means of a sampling capillary and dilution system interfaced to an electrical aerosol analyzer, a condensation nucleus counter and an electrostatic aerosol s...

Studies on the metabolism of iron-containing proteins with radioactive carbon and iron.

Hemoglobin, of the iron-containing compounds, has received the most attention because of its quantitative importance and ease of isolation. In contrast, tracer studies with radioiron of ferritin, cytochrome c, and myoglobin, which are more difficult to isolate, have been less numerous. The uptake of Cl4 by these proteins has received almost no study. Of particular interest in relation to the pr...

Ultrafine and respirable particles in an automotive grey iron foundry.

Ultrafine particle number and respirable particle mass concentrations were measured throughout an automotive grey iron foundry during winter, spring and summer using a particle concentration mapping procedure. Substantial temporal and spatial variability was observed in all seasons and attributed, in part, to the batch nature of operations, process emission variability and frequent work interru...

Nanotoxicology: An Emerging Discipline Evolving from Studies of Ultrafine Particles

Although humans have been exposed to airborne nanosized particles (NSPs; < 100 nm) throughout their evolutionary stages, such exposure has increased dramatically over the last century due to anthropogenic sources. The rapidly developing field of nanotechnology is likely to become yet another source through inhalation, ingestion, skin uptake, and injection of engineered nanomaterials. Informatio...

Ultrafine particles in cities.

Ultrafine particles (UFPs; diameter less than 100 nm) are ubiquitous in urban air, and an acknowledged risk to human health. Globally, the major source for urban outdoor UFP concentrations is motor traffic. Ongoing trends towards urbanisation and expansion of road traffic are anticipated to further increase population exposure to UFPs. Numerous experimental studies have characterised UFPs in in...
