Experimental Studies on CO2 Hydrate Formation Kinetics With Kinetic Promoters
Asia-Pacific Journal of Chemical Engineering, EarlyView.ABSTRACT Carbon dioxide (CO2) sequestration by means of gas hydrate formation is a promising method for mitigating global climate change. However, conventional surfactants like sodium dodecyl sulfate (SDS) exhibit limitations such as excessive foaming and environmental toxicity. This study examines the effectiveness and environmental impact of Tween 65

Comparative Meta‐Analysis of Antimicrobial Peptides in Aquatic and Terrestrial Livestock Species
Animal Research and One Health, EarlyView.A global meta‐analysis of 58 studies (926 effect sizes and 29 species across five taxa) revealed that dietary antimicrobial peptides generally improve growth performance, blood metabolites, and immune responses. The greatest benefits were observed in omnivorous livestock, such as pigs and chickens. Dose‐duration effects were evident. An optimal outcome
