Preliminary Study on the Cloud Condensation Nuclei (CCN) Activation of Soot Particles by a Laboratory-scale Model Experiments

open access: yesAsian Journal of Atmospheric Environment, 2014
To visually and chemically verify the rainout of soot particles, a model experiment was carried out with the cylindrical chamber (0.2 m (D) and 4 m (H)) installing a cloud drop generator, a hydrotherometer, a particle counter, a drop collector, a ...

Experimental Analysis of Combustion and Emission Characteristics of a Diesel Engine Using Diesel-Biodiesel-Methanol Blends With Cetane Enhancer Additive Under Pilot Injection Mode. [PDF]

open access: yesGlob Chall
The work represented in the manuscript is based on resolving the major issue of increased smoke emissions under pilot injection mode while maintaining the core benfits of it, that is, lower nitrogen oxides (NOx) emissions and improved fuel economy. This was achieved by inclusion of methanol and cetane enhancer (CE) in the base fuel.

Quantitative 3D Real‐Space Analysis of Photonic Supraparticles

open access: yesAdvanced Materials, EarlyView.
This work shows that through quantitative 3D real‐space analysis, photonic supraparticles can be investigated in detail. By clustering and classifying all particles, structure features can easily be detected, and the internal structure can be quickly investigated. This methodology allows for quick identification of different crystal structures, such as

Scalable and Customizable Single‐Atom Coatings for pH‐Universal H2O2 Electrosynthesis

open access: yesAdvanced Materials, EarlyView.
A universal one‐step soot‐deposition route was developed to convert various metal‐containing paraffins into conformal single‐atom catalyst (SAC) coatings on diverse electrodes, yielding robust, efficient SAC‐coated gas diffusion electrodes for H2O2 electrosynthesis.

Insights into the role of soot aerosols in cirrus cloud formation [PDF]

open access: yesAtmospheric Chemistry and Physics, 2007
Cirrus cloud formation is believed to be dominated by homogeneous freezing of supercooled liquid aerosols in many instances. Heterogeneous ice nuclei such as mineral dust, metallic, and soot particles, and some crystalline solids within partially soluble

Stochastic Simulation of Soot Formation Evolution in Counterflow Diffusion Flames

open access: yesJournal of Nanotechnology, 2018
Soot generally refers to carbonaceous particles formed during incomplete combustion of hydrocarbon fuels. A typical simulation of soot formation and evolution contains two parts: gas chemical kinetics, which models the chemical reaction from hydrocarbon ...

Simulated contrail-processed aviation soot aerosols are poor ice-nucleating particles at cirrus temperatures [PDF]

open access: yesAtmospheric Chemistry and Physics
Aviation soot surrogates processed in contrails are believed to become potent ice nuclei at cirrus temperatures. This is not verified for real aviation soot, which can have vastly different physico-chemical properties.
