Alkali‐Catalyzed Synthesis of Acylglycerol Estolides Exclusively from Castor Oil

Journal of the American Oil Chemists' Society, EarlyView.
This work advances sustainable chemistry by converting renewable castor oil into high‐performance estolides via solvent‐free, low‐energy catalysis. ABSTRACT Estolides are oligomers composed of fatty acid (FA) monomers linked through secondary ester bonds located along the mid‐chain region.

Polymeric nano‐delivery of gibberellic acid enhances fruit quality, yield and pedicel strength in grapevine (Vitis vinifera L.)

Journal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Nanoparticulate systems offer an effective strategy for the targeted delivery of agrochemicals and for enhancing their efficacy. This study aimed to synthesize and characterize gibberellic acid (GA3)‐loaded poly(d,l‐lactic‐co‐glycolic acid) nanoparticles (PLGA NPs) and to evaluate the effects of their application on the flower ...

Chemical Ionization Mass Spectrometry: Fundamental Principles, Diverse Applications, and the Latest Technological Frontiers

Mass Spectrometry Reviews, EarlyView.
ABSTRACT The review examines the evolution of chemical ionization mass spectrometry (CI‐MS), a technique developed in 1966 by Field and Munson. CI is a soft‐ionization method that produces more intense molecular ions with less fragmentation than electron ionization (EI).

Bulbophyllum weddellii (Orchidaceae) demonstrates foliar water uptake plasticity along Brazilian campos rupestres

Nordic Journal of Botany, EarlyView.
Phenotypic plasticity can facilitate species survival in a variety of conditions that are not possible with a fixed phenotype. Foliar water uptake (FWU), defined as the absorption of water through leaf surfaces, is an important mechanism contributing to plant water balance and drought tolerance in many species.

Effects of bioinsecticide exposure route on aphids and their natural enemies in oilseed rape

Pest Management Science, EarlyView.
Fatty acids, silicone polymers and surfactants reduced aphid numbers but caused natural enemy mortality under direct exposure, while minimal residual activity suggests potential for targeted, compatible use in integrated pest management. Abstract BACKGROUND Myzus persicae Sulzer and Brevicoryne brassicae L.

Evolutionary trade‐offs between beauvericin production and growth define divergent virulence strategies in Beauveria

Pest Management Science, EarlyView.
Two virulence strategies in Beauveria: a growth strategy characterized by rapid within‐host proliferation, and a toxin strategy involving antimicrobial activity and toxicity to insects Abstract BACKGROUND Pathogen virulence is often attributed to toxin production, yet toxins are metabolically costly and may not universally enhance fitness.
