Summary: Ionic liquids play a dual role as solvents and catalysts in the in situ transesterification of wet algae. We studied the variations in fatty acid methyl ester (FAME) yields and cellulose solubilities of three types of ionic liquids ([Bmim][HSO4], [Bmim][H2PO4], and [Bmim]2[HPO4]) under different water conditions. Our results show that the catalytic properties and cellulose solubilities of the ionic liquids compete with each other under different water contents.

Summary: Tigernut, a tuber grown in non-arable land of Xinjiang, China, is a potential feedstock for biofuel production due to its high lipid content and low water and land requirements. Previous studies have mainly focused on transesterification for biodiesel production, limiting the bio-oil yield. This study examines the hydrothermal liquefaction (HTL) of tigernut biomass using MgAl-layered double hydroxides as catalysts. The results show that increasing reaction temperature and optimizing Mg/Al ratio enhance both bio-oil yield and deoxygenation. MgAl-LDHx catalysts show promise for the decomposition of tigernut and hydrodeoxygenation of bio-oil, providing a potential strategy for bio-oil production.

Summary: Fluorescence microscopy is an important tool in cell biology research, but its use for long-term and strong-illumination imaging of live cells is limited by photobleaching and phototoxicity. This study introduces a new concept of fluorophore engineering chemistry, using synchronous photoactivation-imaging (SPI) fluorophores to overcome these limitations. The SPI fluorophores allow continuous replenishing of bright-state probes and reduce photocytotoxicity, enabling long-term imaging of live cells under intensive illumination.

Summary: This paper developed a machine learning model to predict the biochemical methane potential during anaerobic digestion. Model analysis identified lignin content, organic loading, and nitrogen content as key attributes for methane production prediction. For feedstocks with high cellulose content, early methane production is lower but can be improved by prolonging digestion time. Moreover, lignin content exceeding a certain value significantly inhibits methane production.
