Hydrothermal Liquefaction of Jatropha curcas (J. curcas) Under Subcritical Water Conditions: Water and Palm Oil Mill Effluent as Solvents

open access: yesEngineering Reports, Volume 7, Issue 6, June 2025.
J. curcas was hydrothermally liquefied (HTL) using water and palm oil mill effluent (POME) as a hydrogen donor solvent. Palmitic and oleic acids were detected by the POME analysis utilizing GC–MS by manipulating three parameters (temperature, reaction time, and biomass‐to‐solvent ratio).

Photoredox Autocatalysis: Towards a Library of Generally Applicable Sulfonamide Reductive Photocatalysts

open access: yesAngewandte Chemie International Edition, Volume 64, Issue 22, May 26, 2025.
Photoredox autocatalysis is revealed to access cyclic biaryl sulfonamides (BASNs) without an initial exogenous photocatalyst. While unveiling photoredox autocatalysis is important to the enrichment of basic research, this has also led to further practical applications such as rapid discovery of novel, potent and readily accessible photocatalyst ...

Spring nitrogen and plant growth regulator effects on seed yield of orchardgrass

open access: yesCrop Science, Volume 64, Issue 6, Page 3533-3540, November/December 2024.
Abstract Orchardgrass (Dactylis glomerata L.) is an important forage seed crop, but unlike other cool‐season grasses, seed yields have not increased over time. Seed yield increases in orchardgrass may be possible with plant growth regulators (PGRs) such as trinexapac‐ethyl (TE) and chlormequat chloride (CCC).

Carboxylic Acids with Certain Molecular Structures Decrease Osmotic Fragility against Osmotic Pressure in Cattle Erythrocytes In Vitro: Appearance of a Wedge-like Effect Similar to RBCs in Other Animal Species

open access: yesBiochemistry & Pharmacology Open Access, 2019
Osmotic fragility (OF) in red blood cells (RBCs) is a useful tool for evaluating the actions of various chemicals on the cell membrane in vitro. The effects of monocarboxylic and dicarboxylic acids on OF were evaluated in cattle RBCs.
