Estimation of soot absorption function via the two separated pulses laser-induced incandescence technique

open access: yes, 2023
International audienceAn original in-situ experimental approach is proposed to estimate the absorption function of soot particles in flames: the two Separated Pulses Laser-Induced Incandescence technique (SP-LII).

First Steps towards a Super-Compact In-Situ Laser-Induced-Incandescence Sensor System

open access: yesProceedings, 2019
To realize an actual in-situ Laser-Induced Incandescence (LII) sensor system for measurements in an exhaust pipe of a combustion engine, suitable components for such an application were chosen, integrated in a first prototype and tested.

Studying the Bulk and Contour Ice Nucleation of Water Droplets via Quartz Crystal Microbalances

open access: yesMicromachines, 2021
Due to the stochastic and time-dependent character of the ice embryo formation and growth (i.e., a process that can be analyzed statistically, but cannot be predicted precisely), the heterogeneous ice nucleation on atmospheric aerosols or macroscopic ...

Utterance evolution: the road to generative, combinatorial communicators

open access: yesBiological Reviews, EarlyView.
ABSTRACT Language has long been considered uniquely complex in the animal kingdom; however, animal research over the last decade has begun to challenge some long‐standing premises about exactly which language capacities are uniquely human. The task of resolving why and how complex communication systems evolve, particularly human language, has ...

Soot and charcoal as reservoirs of extracellular DNA

open access: yes, 2022
The vast potential of using sediment adsorbed DNA as a window to past and present biodiversity rely on the ability of solid surfaces to adsorb environmental DNA. However, a comprehensive insight into DNA adsorption at surfaces in general is lacking. Soot

A computationally efficient approach for soot modeling with discrete sectional method and FGM chemistry [PDF]

open access: yes, 2023
A novel approach for the prediction of soot formation in combustion simulations within the framework of discrete sectional method (DSM) based univariate soot model and Flamelet Generated Manifold (FGM) chemistry, referred to as FGM-CDSM, is proposed in ...

Effect of H2/CO addition on soot formation in ethylene diffusion flame

open access: yesFrontiers in Energy Research
Coupling the San Diego gas phase reaction mechanism and the Moss Brookes soot model using FLUENT14.0 software, the effect of adding H2/CO on the fuel side on soot formation in an ethylene/air laminar diffusion flame was studied.

Morphology of diesel soot residuals from supercooled water droplets and ice crystals: implications for optical properties

open access: yesEnvironmental Research Letters, 2015
Freshly emitted soot particles are fractal-like aggregates, but atmospheric processes often transform their morphology. Morphology of soot particles plays an important role in determining their optical properties, life cycle and hence their effect on ...

Effect of Pore Structure on Soot Deposition in Diesel Particulate Filter

open access: yesComputation, 2016
Nowadays, in the after-treatment of diesel exhaust gas, a diesel particulate filter (DPF) has been used to trap nano-particles of the diesel soot. However, as there are more particles inside the filter, the pressure which corresponds to the filter ...

AIR POLLUTION IN KRAKOW – A GLANCE INTO THE FUTURE FROM A HISTORICAL PERSPECTIVE [PDF]

open access: yesActa Geobalcanica, 2017
High concentrations of air pollution probably occurred in Krakow in the nineteenth and early twentieth centuries. Since the late 1960s due to the development of monitoring networks level of air pollution is well documented.
