Experimental Investigation of Burning Liquids in Reduced Oxygen

Fire and Materials, EarlyView.
ABSTRACT The effects of oxygen concentration on combustion of gases have been investigated on fundamental levels in several studies. However, the same type of fundamental studies has not been made for liquid or solid fuels due to complex relationships between flame structure and changing mass loss rates (MLR).

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).

Curvature and Microenvironment Regulation Enable Robust Seawater Electrochemical Hydrogen Peroxide Synthesis for On‐Site Marine Aquaculture

Interdisciplinary Materials, EarlyView.
This work designs pentagon‐defect‐enriched interconnected spherical carbon (PD/IS‐C) via curvature and microenvironment co‐engineering for seawater H2O2 electrosynthesis. Curvature modulates electronic structure to boost reactivity, while local alkaline microenvironment repels Cl− for enhanced stability, endowing PD/IS‐C with exceptional catalytic ...
