The average particle size of the colloidal silica dispersion measured by the dynamic light scattering method is 40 to 200 nm, and the silica particles in the dispersion have an average primary particle size measured by the nitrogen gas adsorption method of 10 to 80 nm. [Selection diagram] None...
In the present study, optimal health-relevant air pollution control strategies for industrial plants are proposed by integrating source-specific toxic potencies and pollution reducing costs. The three most polluting industrial sectors, i.e., the iron and steel industry (ISI), cement industry, and p...
In turn, semi-volatile pesticides may be simultaneously present in both particulate and gaseous phases. It is known that compounds with vapor pressure higher to 10−2 Pa are principally observed in the gas phase and those with vapor pressure lower than 10−5 Pa are almost exclusively ...
Thermal gravimetric analysis (TGA) measures pyrolytic mass-loss as a function of temperature. Coupling the instrument to a Fourier-transform infrared spectrometer (TGA-FTIR) enabled identification of products in the outgoing gas stream, and measurement of natural and synthetic rubber, carbon black, and...
All particles were sampled on the 81 mm quartz microfiber filters (Whatman QMA grade, UK) according to the size ranges and a group of blank samples were collected synchronously during each sampling to correct the concentrations measured in the dissolved filters. In addition, the filters were ...
PURPOSE:To produce dispersed crystalline fine platinum particles having a narrow particle size distribution when a reducing gas is blown into an aq. chloroplatinic acid soln. under ordinary temp. and pressure to reduce the soln., by specifying the concn. of Pt in the soln. and keeping the ...
allowed to coexist in the gas phase where competing homo- geneous reactions form nanoparticles that are ultimately scavenged on the substrate particles. A CVD reaction occurs continuously with no self-control and is dependent upon reaction time, reactant exposure, pressure, and tem- ...
However, it has also been shown that NoV can bind to enterocytes independently of HBGAs [22]. Human NoVs have for long time been elusive to propagation in cell cultures [23, 24], although it has been recently reported that human NoVs can infect B lymphocytes in the presence of HBGA-...
Welding fumes induce lung toxicity and are carcinogenic to humans but the molecular mechanisms have yet to be clarified. The aim of this study was to evaluate the toxicity of stainless and mild steel particles generated via gas–metal arc welding using p
