In addition to public health measures, including social distancing, masking, cleaning, surface disinfection, etc., ventilation and air filtration can be a key component of multi-pronged risk mitigation strategy against COVID-19 transmission indoors. Electrostatic precipitators (ESP) have already proved their high performance in fluid filtration, particularly industrial applications, control exh...

Nanoparticles have shown great potential in many sectors of the oil and gas industry, including enhanced recovery (EOR). They can be used to improve water flooding by altering wettability porous medium, reducing interfacial tension, blocking pores, or preventing asphaltene precipitation. Ensuring stability nanofluids injected into reservoirs is essential a challenge. However, high temperature f...

influence of aluminum, gallium, indium- doping on the boron-nitride nanotubes (bnnts) investigated with density functional theory (dft) and hartreefock (hf) methods. for this purpose, the chemical shift of difference atomic nucleus was studied using the gauge included atomic orbital (giao) approch. in the following, structural parameter values, electrostatic potential, thermodynamic parameters,...

in this paper, we investigated the corrected plasmon dispersion relation for graphene in presence of a constant magnetic field which it includes a quantum term arising from the collective electron density wave interference effects. by using quantum hydrodynamic plasma model which incorporates the important quantum statistical pressure and electron diffraction force, the longitudinal plasmons ar...

Abstract In this study, a flame-generated nm-range SiO 2 aerosol (approx. 170 nm median aggregate diameter) is fed into an electrostatic precipitator with operating temperature of 200 °C. While highly porous layer nanoparticles (NPs) deposited by precipitation, decrease current uptake observed initially, indicating exceptionally high values the electric field within (> 100 kV/mm) and resisti...
