SOOT VOLUME FRACTION MEASUREMENTS IN A THREE-DIMENSIONAL LAMINAR DIFFUSION FLAME ESTABLISHED IN MICROGRAVITY [PDF]

Combustion Science and Technology, 2006
A methodology for the estimation of the soot volume fraction in a three-dimensional laminar diffusion flame is presented. All experiments are conducted in microgravity and have as objective producing quantitative data that can serve to estimate radiative heat transfer in flames representative of fires in spacecraft.

Beyond the Reports: Cultural Pressures, Unheard Voices and the Climate Accountability Gap in Oil and Gas Sector Governance

Business Strategy and the Environment, EarlyView.
ABSTRACT Environmental governance in Nigeria's oil and gas sector remains central to global climate justice debates, yet persistent accountability failures continue to undermine meaningful environmental and social outcomes. Despite extensive regulatory frameworks, accountability in resource‐dependent contexts is frequently reduced to formal reporting ...

Investigation of Soot Formation in a Novel Diesel Fuel Burner

Energies, 2019
In the present work, a novel burner capable of complete pre-vaporization and stationary combustion of diesel fuel in a laminar diffusion flame has been developed to investigate the effect of the chemical composition of diesel fuel on soot formation.

Functionalized Organic Lithium Salt Enables Flexible Solid‐State Electrolytes With Dual‐Ion Channels for Safe Li Metal Batteries

Carbon Energy, EarlyView.
Here, we design a flexible and non‐flammable solid‐state electrolyte with hierarchical dual‐ion conductive channels. The engineered electrolyte combines continuous organic conductive‐phase pathways for fast bulk Li+ transport and dynamic polymer networks for interfacial ion hopping, achieving unprecedented room temperature conductivity (> 1 mS cm−1 ...
