Comparative Study of Different Methods for Soot Sensing and Filter Monitoring in Diesel Exhausts

Sensors, 2017
Due to increasingly tighter emission limits for diesel and gasoline engines, especially concerning particulate matter emissions, particulate filters are becoming indispensable devices for exhaust gas after treatment.

Investigation of Soot Formation in a Novel Diesel Fuel Burner

Energies, 2019
In the present work, a novel burner capable of complete pre-vaporization and stationary combustion of diesel fuel in a laminar diffusion flame has been developed to investigate the effect of the chemical composition of diesel fuel on soot formation.

Spectral albedos of midlatitude snowpacks [PDF]

Spectral albedos of impure-nonhomogeneous snowpacks, typical of midlatitudes, from 400 to 2200 nm were modeled through a numerical solution of the radiative transfer equation in the two-stream approximation.

Regulation Through Revelation: The Effect of Pollution Monitoring on Labour Demand

Business Strategy and the Environment, EarlyView.
ABSTRACT This paper investigates how manufacturing firms respond to a real‐time pollution monitoring programme, with a focus on the implication for employment. Contrary to the conventional expectation that environmental regulations negatively impact business, the findings reveal that enhanced pollution monitoring has a significant and robust positive ...

Influence of Lowering Soot‐Water Contact Angle on Ice Nucleation of Ozone‐Aged Soot

Geophysical Research Letters
Organic‐lean and organic‐rich size‐selected soot particles were exposed to a varying O3 concentration, progressively decreasing the soot‐water contact angle (θ) to study its impact on ice nucleation (IN).

Modelling and simulation of hydrogen production via natural gas plasma pyrolysis

The Canadian Journal of Chemical Engineering, EarlyView.
Methane pyrolysis simulation model. Abstract Plasma pyrolysis is a cutting‐edge technology that produces hydrogen and solid carbon from methane without emitting carbon dioxide. In this study, we developed a process simulation model in Aspen HYSYS to analyze the behaviour of this technology at the commercial scale.
