Ni/CeO2 catalysts incorporated with cassava-peel-derived biochar for CO2 methanation: Effects of biochar activation and impregnation route

Modifying highly active Ni/CeO 2 catalysts with less expensive materials whilst maintaining their catalytic activity is a challenging yet intriguing research direction. Herein, biochar was engineered from cassava peels and introduced into a Ni/CeO 2 -based catalyst for methanatio...

Visible-Light-DrivenPorphyrin/ZnO Nanohybrids forUltrasensitive Room-Temperature Triethylamine Sensing

Abstract Real-time monitoring of toxic triethylamine (TEA) at room temperature remains a significant challenge for metal oxide chemiresistors due to their typically high-power consumption and thermal requirements. This work presents a highly responsive, visible-light-activated ga...

A new genus and species of hagfish from Vietnam: A transitional lineage between Rubicundinae and Myxininae (Craniata: Myxiniformes)

Abstract Dolichostomus leucotaenia gen. et sp. nov. is described from two specimens collected from off northern Vietnam. It is characterized by a long, oval mouth opening visible from the ventral view, a feature unique among the order Myxiniformes. It also possesses a single medi...

One-step method for preparation of Fe3O4/g-C3N4 composite using hydrazine for heterogeneous photocatalysis

Environmental pollution and the global energy demand have significantly increased, necessitating sustainable development strategies, with advanced functional materials emerging as key solutions. Specifically, photocatalysis technology has attracted considerable attention due to i...

Identification active compounds from Dregea volubilis that improve insulin secretion by regulating pancreatic β ‐cell metabolism

Abstract Type 2 diabetes (T2D) occurs due to a lack of insulin secretion by glucose stimulation, so high blood glucose levels predominate that associated with metabolic dysregulation. The exploration of bioactive compounds from natural sources has attracted considerable attention...

Beyond Morphological Conservatism: Integrative Taxonomy Unveils Remarkable Cryptic Diversity in the Tachysurus virgatus (Oshima 1926) Group (Siluriformes: Bagridae) Endemic to the Northern Margin of East Asian Tropics

The northern margin of the East Asian tropics harbors exceptional endemism, yet its freshwater fish fauna remains poorly characterized. Tachysurus virgatus, long considered a single widespread species in this region, exemplifies this taxonomic gap. Through integrative taxonomic a...
