Downdraft Devices for Negative Emissions—Quantification Study and Environmental Implication

open access: yesGreenhouse Gases: Science and Technology, Volume 16, Issue 1, Page 75-89, February 2026.
ABSTRACT Methane (CH4) is a potent greenhouse gas with a global warming potential far exceeding that of CO2 over short time horizons. Its removal from the atmosphere remains challenging due to its low ambient concentration and chemical stability. This study explores downdraft energy towers (DETs) as an innovative CH4 mitigation technology that enhances

Numerical Model and Experimental Validation of Composite Metal Foam in Protecting Carbon Steel Against Puncture

open access: yesAdvanced Engineering Materials, Volume 28, Issue 1, January 2026.
The puncture prevention and energy absorption performance of composite metal foam (CMF) are studied experimentally and numerically for hazardous materials transportation protection. The numerical model implementing air within the CMF (nonhomogeneous model using fluid cavity technique) predicts puncture more accurately compared to the homogeneous CMF ...
