Unlocking Methane Generation via Photo‐Thermal‐Coupled CO2 Hydrogenation by Integrating FeNiCrMnCo Multicomponent Alloy with GaN Nanowires

open access: yesAdvanced Science, EarlyView.
A noble‐metal‐free FeNiCrMnCo multicomponent alloy (MCA) integrated with GaN nanowires achieves efficient photo‐thermal‐coupled CO₂ methanation, delivering a methane production rate of 199 mmol∙g−¹∙h−¹ with 93% selectivity. The system demonstrates exceptional stability and tunable catalytic properties, offering a sustainable pathway for solar‐driven ...

Nutritional and host effects on methanogenesis in the grazing ruminant

open access: yesAnimal, 2013
Concentrations of methane (CH4) in the atmosphere have almost doubled since the mid 1700s, and it is estimated that ∼30% of the global warming experienced by the planet in the last century and a half can be attributed to CH4.

Marginal abatement cost of electricity generation from renewable energy in Thailand

open access: yesEnergy Reports, 2020
Electricity is very important for daily living and plays a major role in national development in Thailand with around 20.5% proportion in national final energy consumption, mainly from burning fossil fuels which have a direct effect to the greenhouse gas

Diurnal Release of Airborne Pathogen Spores in Greenhouses via the Synergistic Effects of Relative Humidity and Wind

open access: yesAdvanced Science, EarlyView.
Day‐night cycles trigger sharp relative humidity (RH) shifts in greenhouses. Rapid humidity drops dehydrate Corynespora cassiicola spores, inducing shrinkage, jerking movements, and weakened inter‐spore connections that drive detachment. Wind is essential for dispersal, with even mild airflow enabling rapid pathogen spread. These synergistic effects of

Activity‐Selectivity Trends in Electrochemical Urea Synthesis: Co‐Reduction of CO2 and Nitrates Over Single‐Site Catalysts

open access: yesAdvanced Science, EarlyView.
In this work, a series of single‐site metal phthalocyanine catalysts (MPcs (M = Zn, Co, Ni, Cu, and Fe)) are screened to learn their activity‐selectivity relationship in the co‐reduction reaction of CO2 and nitrates toward urea formation, which can be significantly promoted by enhanced adsorption of *HOOCNO, reduced adsorptions of *N and *COOH, and ...
