Jacks. ex Andrews, is cultivated for its aromatic pods, obtaining the primary source of vanillin, a molecule valued for its flavor and bioactivity. Mexico ranks among the top five global producers, and Papantla, Veracruz, contributes 70 % of national production. Developing vanilla's characteristic aroma involves a curing process composed of killing, sweating, drying, and conditioning, which enzymatic reactions and microbial activity play essential roles. This study assessed the impact of four killing treatments: microwave, hot water immersion, sonication, and freezing on the phenolic composition and bacterial communities in vanilla curing through metabolomic and 16S sequencing approaches. Freezing treatment resulted in the most substantial changes in phenolic profiles, including higher vanillin concentrations. was the dominant bacterial genus, with hot water immersion and sonication showing the greatest α-diversity. These findings underscore the value of omic sciences in refining curing processes, enabling producers to achieve higher-quality vanilla through more efficient and technical methods.

Traditionally unsustainable and nondegradable fossil-based based plastics have resulted in serious environment pollution problem. Renewable and biodegradable lignocellulose biomass is a promising raw martial for developing environmentally friendly plastic alternatives. However, lignocellulose biomass itself is non-thermoplastic crosslinking networks consisting of cellulose, lignin, and hemicellulose, resulting in a huge challenge to thermoform its into plastic alternatives.

In this study, metabolomics and chemometrics were utilized to comprehensively investigate chemical mechanisms of aroma, taste, and color formation in cold-brewed green tea (4 °C). The results showed that the typical flavor of cold-brewed green tea (tea-to-water ratio: 1:50 g/mL) developed gradually after 1 h. Compared with the hot-brewed (80 °C) condition, volatile alcohols accumulated more under cold-brewing conditions.

Developing high-performance photothermal materials and unraveling the underlying mechanism are essential for photothermal applications. Here, photothermal performance improved by strong interaction between plasmon and topological surface state (TSS) is demonstrated in BiSe/CuS nanowires. This hybrid, which CuS nanosheets were grown on BiSe nanowires, leverages the plasmon resonance and TSS-induced optical property, generating wide and efficient light absorption.

An investigation was conducted to assess the efficacy of a novel antioxidant supplementation, Transcare, in alleviating transportation-induced stress among Bannur sheep. Thirty female Bannur sheep of 10-12 months, were selected and randomly assigned to two groups: Bannur Non-supplemented (BNS) (n = 15) and Bannur Supplemented (BS) (n = 15). The BS was supplemented with antioxidant powder (Transcare) orally at a dose of 10 g/animal, dissolved in 10 mL drinking water, 45-60 min preload.

Photocatalytic hydrogen production through water splitting represents a promising strategy to store solar energy as chemical energy. Current photocatalysts primarily focus on traditional semiconductor materials, such as metal oxides, sulfides, nitrides, g-CN, etc. However, these materials often suffer from large bandgap and fast charge recombination, which limit sunlight utilization and result in unsatisfactory photon conversion efficiency.
