Investigation of ethanol blending on soot particle evolution in counterflow diffusion flames of a gasoline surrogate

Applications in Energy and Combustion Science
Across all transport sectors, there is an increasing recognition of the importance of reducing not only CO2 emissions but also other climate-impacting pollutants, such as soot particulate matter.

Recent Advances of Perovskite Oxides for Air Pollution Control Chemistry: The Closed Loop From Design to Application

EcoEnergy, EarlyView.
This review summarizes a descriptor‐guided framework for linking theoretical calculations, in situ/operando characterization, synthesis regulation, and application screening in functional materials. Emphasis is placed on dynamic structure–property relationships that enable low‐cost material design with enhanced activity, stability, and environmental ...

Exploring Soot Particle Concentration and Emissivity by Transient Thermocouples Measurements in Laminar Partially Premixed Coflow Flames

Energies, 2017
Soot formation in combustion represents a complex phenomenon that strongly depends on several factors such as pressure, temperature, fuel chemical composition, and the extent of premixing. The effect of partial premixing on soot formation is of relevance

Microclimate mediates the strength and direction of avian biotic interactions

Ecography, EarlyView.
Theory predicts that the strength and direction of species interactions can shift from being competitive in benign environments toward being facilitative in stressful environments. However, the environmental context dependency of species interactions has rarely been tested in animal communities.

Carbon Nanopatch‐Decorated Defect‐Rich Regions for Stable Zinc Metal Anodes

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
To improve the stability of Zn anodes, a carbon‐nanopatch strategy based on candle‐flame pyrolysis is proposed. After rinsing, carbon nanoparticles are mainly retained in defect‐rich regions on the Zn surface, where they help alleviate local field intensification, improve interfacial uniformity, and mitigate parasitic reactions.

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).

Laser-Powered Homogeneous Pyrolysis (LPHP) of Lignin Dispersed into Gas Phase

Molecules
The gas-phase delivery of lignin into the hot zone of cw-CO2 laser-powered homogeneous pyrolysis (LPHP) reactor under “wall-less” conditions led to the breakdown of lignin macromolecules into neutral oligomers and paramagnetic fragments deposited onto ...
