Effects of dielectric-barrier-discharge plasma on soot and NOx in diffusion flame

open access: yesJournal of Thermal Science and Technology, 2022
In this study, we experimentally investigated soot and NOx in a diffusion flame on a coaxial burner. By applying a dielectric-barrier-discharge (DBD) plasma, we tried to reduce these emissions.

Evaluation of the impact of black carbon on the worsening of allergic rhinitis and asthma in the region of Uzice Serbia [PDF]

open access: yesMedicinski Glasnik Specijalne Bolnice za Bolesti Štitaste Žlezde i Bolesti Metabolizma "Zlatibor", 2021
Many epidemiological studies have shown a positive association between black carbon (BC) concentrations and exacerbation of allergic rhinitis and asthma. The aim of this study was to examine, for the first time in Serbia, the connection between visits to

Classification of contaminants in diesel engine oils

open access: yesВестник СибАДИ, 2022
Introduction. The deterioration of engine oil in an internal combustion engine (ICE) is directly related to the ingress of various pollutants into the crankcase. Depending on the type of contamination, the type of sediment on engine part surfaces varies.

A study on the influence of inorganic ions, organic carbon and microstructure on the hygroscopic property of soot [PDF]

open access: yesAtmospheric Chemistry and Physics
Soot is a crucial component of aerosols in the atmosphere. Understanding the hygroscopicity of soot particles is important for studying their role as cloud condensation nuclei (CCN) as well as their chemical behavior and atmospheric lifetime.

Tunable surface adsorption and wettability of candle soot coated on ferroelectric ceramics

open access: yesJournal of Advanced Research, 2019
A ferroelectric Ba0.85Ca0.15Ti0.9Zr0.1O3 (BCZTO) ceramic was prepared using a solid-state reaction route. A coating of candle soot was provided on poled and unpoled BCZTO samples.
