Liquid‐Mediated Sintering of SnO2 Scaffolds for Hybrid Integration of Conductive Cu3(HHTP)2

open access: yesSmall Structures, EarlyView.
A versatile strategy for creating hybrid metal–oxide/metal‐organic framework architectures by combining flame spray pyrolysis with liquid‐mediated sintering and vapor‐assisted growth. Porous SnO2 films are transformed into mechanically robust nano–microcluster arrays that are interconnected with conductive Cu3(HHTP)2.

Performance, emissions, and lubricant oil analysis of a marine diesel engine powered by raw Schizochytrium sp. and its blends

open access: yesBiofuels, Bioproducts and Biorefining, Volume 20, Issue 1, Page 136-154, January/February 2026.
Abstract Microalgae oil (MAO), a third‐generation biofuel, can support global transportation fuel demand as a fossil fuel substitute. Schizochytrium sp. MAO is particularly promising for direct use in compression ignition (CI) engines, especially in the marine sector, due to its adaptability and high oil yield.
