Experimental and Numerical Investigation of Cedar Façade Flame Spread With Respect to Sidewall

Fire and Materials, EarlyView.
ABSTRACT In response to growing energy conservation and carbon neutrality efforts, façade systems incorporating wooden materials have attracted increasing attention, which in turn raises concerns about their combustibility. This study presents a combined experimental and numerical investigation of flame spread along cedar façades.

Formation of PAHs and Carbonaceous Solids in Gas-Phase Condensation Experiments [PDF]

, 2009
Carbonaceous grains represent a major component of cosmic dust. In order to understand their formation pathways, they have been prepared in the laboratory by gas-phase condensation reactions such as laser pyrolysis and laser ablation.

An Experimental Investigation on the Impact of Burner Height and Location on the Characteristics of Externally Venting Flames

Fire and Materials, EarlyView.
ABSTRACT Fire sources in actual compartment fires exhibit a predominantly uneven spatial distribution. In this context, the impact of the height and location of the fire source, as well as the heat release rate (HRR) of the fire, on the thermal characteristics of Externally Venting Flames (EVF) is experimentally investigated.

Impact of simulated airborne soot on maize growth and development [PDF]

, 2012
Various effects of the dry deposition of soot on maize were investigated in Keszthely (Hungary) in two consecutive years. In order to be able to study a wider range of weather conditions, some of the plants were placed in a Thorn-thwaite-Matter type ...

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 ...

Laboratory measurements in a turbulent, swirling flow [PDF]

Measurements of soot inside a flame-tube burner using a special water-flushed probe are discussed. The soot is measured at a series of points at each burner, and upon occasion gaseous constitutents NO, CO, hydrocarbons, etc., were also measured.
