Interspecific Differences in the Effects on Embryos Between Freshwater and Marine Fish Exposed to Water‐Accommodated Fractions Derived From Very‐Low Sulfur Fuel Oil

Environmental Toxicology, EarlyView.
ABSTRACT This study evaluated the toxic effects of water‐accommodated fractions (WAFs) of very‐low sulfur fuel oil (VLSFO) on freshwater and marine fish embryos. Embryos of Japanese medaka (Oryzias latipes), Java medaka (Oryzias javanicus), and grass puffer (Takifugu alboplumbeus) were exposed to various concentrations of VLSFO‐WAF, and the effects on ...

Enhanced Thermal Durability and Efficiency of Organic Solar Cells via Selective Organic Electron Transport Layers

ENERGY &ENVIRONMENTAL MATERIALS, Volume 9, Issue 4, July 2026.
PDINN‐based organic solar cells exhibit strong thermal durability, maintaining high efficiency at 110°C, whereas PFN‐Br devices degrade rapidly. PDINN's stable interfacial interactions enhance charge transport and suppress recombination, emphasizing the key role of interfacial engineering in achieving thermally durable, high‐performance OSCs.

Tuning catalytic activity and sensitivity in urease‐based thin film biosensors using conjugated polymers and eugenol/biseugenol

Polymer International, Volume 75, Issue 7, Page 609-617, July 2026.
Hybrid thin films of conjugated polymers and urease modified with eugenol derivatives show that polymer–biomolecule interactions enhance catalytic activity while distinctly modulating electrolyte–insulator–semiconductor sensor sensitivity. Abstract Thin films have emerged as promising platforms for biosensor development due to their versatility and ...
