The Future of Hydrogen‐Powered Aviation: Technologies, Challenges, and a Strategic Roadmap for Sustainable Decarbonization

open access: yesAdvanced Energy and Sustainability Research, EarlyView.
Hydrogen‐powered aviation offers a transformative pathway to zero‐emission flight by eliminating in‐flight CO2 emissions. Key considerations include propulsion systems (fuel cells and hydrogen combustion), cryogenic storage and insulation challenges, infrastructure and cost barriers, and supply‐chain constraints.

Engineering Fluoroacetate Dehalogenase by Growth‐Based Selections on Non‐Natural Organofluorides

open access: yesAngewandte Chemie, EarlyView.
We present a high‐throughput selection system to engineer fluoroacetate dehalogenases (FAcDs). By challenging E. coli populations that produce diverse FAcD libraries to grow on non‐natural organofluorides as their sole carbon source, we isolated a panel of FAcD variants with improved activity and altered substrate specificity.

Current Landscape: Use of Supercritical CO2 in the Wood Industry

open access: yesAdvanced Energy and Sustainability Research, EarlyView.
The application of supercritical carbon dioxide (scCO2) to successfully dewater as well as extract resin from wood is becoming increasingly popular due to its greener and less energy‐intensive approach. With world focus shifting to developing methods with greater efficiency while decreasing harm to the environment, scCO2 applications have begun to set ...

Effect Differences of Omega‐3 Fatty Acids From Plant Oil and Fish Oil on Human Health

open access: yesAgriFood: Journal of Agricultural Products for Food, EarlyView.
Omega‐3 fatty acids in plant oil is no less than fish oil on human health. ALA in plant oil takes directly healthy effects without conversion to DHA and EPA. Plant oil can be substitutes for fish oil to support partial ω‐3 fatty acids. For people who cannot afford fish oil, plant oil is also good for public health.
