New Biobased Polyester Polyols With Tunable Tg Values From 4‐Vinylguaiacol‐Derived Monomers

ChemSusChem, Volume 19, Issue 15, 14 August 2026.
Biobased low‐molecular‐weight polyesters were obtained by ROCOP of guaiacol‐derived epoxides with cyclic anhydrides. Varying the length of the acyl moieties on the epoxides and the cyclic anhydride structures, it is possible to tune the Tg's within an 80 ºC wide temperature range.

Biobased Polyurethane Films Based on Andiroba (Carapa guianensis) and Buriti (Mauritia flexuosa) Oil Polyols

Journal of Applied Polymer Science, Volume 143, Issue 30, August 10, 2026.
Polyurethane films were prepared from andiroba (Carapa guianensis) and buriti (Mauritia flexuosa) oil‐derived polyols, emphasizing their potential as bio‐based materials. UV–Vis analysis indicates the retention of carotenoid‐related chromophoric features within the polymer matrix.

Synthesis of Ethyl Methyl Carbonate: Past, Present, and Future

Advanced Synthesis &Catalysis, Volume 368, Issue 15, 1 August 2026.
Ethyl methyl carbonate (EMC) is the simplest asymmetric organic carbonate, with properties between dimethyl (DMC) and diethyl (DEC) carbonate, considered a unique green liquid organic compound for lithium batteries (electrolyte) and gasoline blending (octane enhancer additive), among other uses. In accordance, the chemical production of EMC is expected

Self‐Reporting Diels–Alder Networks: Fluorescent Tracking of Reaction Conversion and Thermal History

Aggregate, Volume 7, Issue 8, August 2026.
This work demonstrates how to track the curing stage within end‐of‐life recyclable Diels‐Alder networks visually through fluorescence, by introducing a small amount of maleimide‐functionalized tetraphenylethylene. The thermochromic behavior is reversible, being particularly useful in self‐healing applications (often requiring local heating) and process

Waste‐to‐Energy Transformation: Performance and Emission Analysis of Diesel–Plastic–Vegetable Fuel Blends

Engineering Reports, Volume 8, Issue 8, August 2026.
DPV blends produced from waste plastic pyrolysis oil and vegetable oils deliver higher engine efficiency and lower emissions compared to diesel. The optimized B60‐PSO blend improves BTE by 12% and reduces BSFC, CO, NOx, and soot, supporting sustainable, circular‐energy solutions.

Metabolite Variations in Lepidium sativum Seeds Among Different Germplasms: Unraveling the Link Between Environment and Chemical Compounds

Food Science &Nutrition, Volume 14, Issue 8, August 2026.
Comparative phytochemical analysis of Lepidium sativum seed populations revealed environmentally driven variation in essential oil composition, while fatty acid profiles remained largely stable across populations. Benzyl nitrile was the dominant essential oil constituent, α‐linolenic acid was the major fatty acid, and all populations exhibited weak ...
