Soft-X-ray-enhanced electrostatic precipitation for protection against inhalable allergens, ultrafine particles, and microbial infections.

Soft X - ray Enhanced Electrostatic Precipitation 1 for Protection against Inhalable Allergens , 2 Ultrafine Particles , and Microbial Infections 3 4

Measurement and capture of fine and ultrafine particles from a pilot-scale pulverized coal combustor with an electrostatic precipitator.

Experiments were carried out in a pilot-scale pulverized coal combustor at the Energy and Environmental Research Center (EERC) burning a Powder River Basin (PRB) subbituminous coal. A scanning mobility particle sizer (SMPS) and an electrical low-pressure impactor (ELPI) were used to measure the particle size distributions (PSDs) in the range of 17 nm to 10 microm at the inlet and outlet of the ...

Investigation of the Mass Attenuation Coefficient for Composites Containing Nano and Micro-Particles of Copper Oxide against Diagnostic X-ray

Radiation protection and the selection of suitable materials to reduce radiation effects is one of the important branches of medical science and radiation. In this paper, the mass attenuation coefficients, half value layer thicknesses and thicknesses of 0/5 mm lead of polyvinyl chloride (PVC) composites containing Nano and micro-particles of copper oxide are calculated using experimental method...

Particle size and kind of mica in synthesis of nontoxic bronze and gold pearlescent pigments based on nanoencapsulated hematite

Nano-encapsulated iron oxide in Zirconium oxide-coated mica pigments are thermally stable,innocuous to human health, non-combustible, and they do not conduct electricity. They could beapplied in several industries such as thermoplastics, cosmetics, food packaging, children toys, paints,automobiles coating, security purposes, and banknotes. Nowadays, they are highly desirable inceramic decoratio...

Synthesis of nanosilica from silica fume using an acid-base precipitation technique and PVA as a nonionic surfactant

The purpose of the present study was to synthesize and characterize nanosilica from alkali-extraction of silica fume under controlled conditions using poly (vinyl alcohol) (PVA) as a dispersing agent. The dissolution efficiency of silica fume was affected by various factors such as concentration of the reagent, reaction time and temperature. A maximum dissolution efficiency of 91% was achieved ...
