Organicphosphorus is a ubiquitous pesticide that has potential hazards to human health and environmental well-being. Therefore, the precise identification of residues of organophosphorus pesticides (OPs) emerges as an urgent necessity. A ratiometric fluorescent sensor for the detection of OPs by leveraging the catalytic activities of Ce and Ce on the two fluorescent substrates 4-Methylumbelliferyl phosphate (4-MUP) and o-phenylenediamine (OPD) correspondingly was designed.

In this study, an integrated approach combining UHPLC-HRMS, H NMR spectroscopy, and sensory analysis unveiled the unique lipid fingerprint of long-ripened Protected Designation of Origin (PDO) Coppa Piacentina. Lipidomic profiling revealed significant alterations in lipid classes, including triacylglycerols, sphingolipids, and their oxidation products, which likely contribute to the distinctive flavor, texture, and nutritional properties of this traditional Italian product. UHPLC-HRMS analysis identified various lipid species, highlighting dynamic changes occurring throughout the 240-day ripening process.

Gelatin, a natural and edible polymer, has attracted wide attention for use in food and edible packaging applications. However, its inadequate properties, especially poor flexibility, limit its broader utilization. Hybridizing different polymers is a promising strategy to achieve enhanced properties.

Kombucha is a fermented beverage with health effects, made mainly from green tea and black tea; however, it can also be made from other leaves such as those of jackfruit and soursop, which are not used even though they have been reported to have positive health effects. Due to the above, in this work "kombucha" beverages based on jackfruit and/or soursop leaves were developed and analyzed to take advantage of these by-products. It was found that fermentation produced significant changes, being the optimal kombucha formulation green tea with soursop leaves (GTKS), obtaining a higher content of antioxidant compounds (mainly catechin, rutin and shikimic acid) and greater ferric reducing antioxidant power (FRAP) (1.

CCTS/DFQM, UFSCar - Campus Sorocaba, Rod. João Leme dos Santos km 110 - SP-264 Bairro do Itinga - Sorocaba CEP 18052-780, Sorocaba, 18052-780, BRAZIL.
Nanomaterials stand out for their exceptional properties and innovative potential, especially in applications that protect against space radiation. They offer an innovative approach to this challenge, demonstrating notable properties of radiation absorption and scattering, as well as flexibility and lightness for the development of protective clothing and equipment. This review details the use of polymeric materials, such as polyimides (PIs), which are efficient at attenuating ultraviolet (UV) radiation and atomic oxygen (AO).
