Energy Science &Engineering, EarlyView.This study concluded that wider spray angles produce wall impingement and greater unburned hydrocarbons in methane‐diesel dual‐fuel engines, whereas 110° balances efficiency and emissions. ABSTRACT A diesel methane dual fuel engine appears as a potential means for lowering emissions while retaining useful thermal efficiency.

Forced Draught Impact on Externally Venting Flames: An Experimental and Numerical Investigation
Fire and Materials, EarlyView.ABSTRACT Wind can significantly influence fire development and spread in urban and forest environments causing fatal consequences for the public, the first responders, and the environment. Wind‐driven fires can have a significant impact on structural fires as wind can increase the fire's intensity, development, and flame spread.

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.

Stand Up, Speak Out: Stimulating Dissent in Social Justice Teacher Education
Future in Educational Research, EarlyView.ABSTRACT Teacher education should not only prepare student teachers for their role in the existing educational system but also equip them to critically question and reform that system when confronted with injustice. We advocate for dissent in the future of teacher education.
