Summary: Large amounts of vine shoots generated during vine pruning still contain compounds from the original plant, including phenolic compounds and structural compounds like cellulose, hemicellulose, and lignin. This study proposes the extraction of lignin from vine shoots for the production of nanoparticles, using ethanol/toluene and water/ethanol as solvents. The lignin nanoparticles showed excellent antioxidant properties and the extracts from biomass pretreatment also exhibited antioxidant activity. Overall, this work contributes to the integral reuse of vine shoot byproduct, promoting sustainability.

Summary: This study evaluated the effects of different drying methods (natural convection, forced convection, and solar drying) on the color, texture, phenol content, and antioxidant capacity of peach. The experimental data were fitted to five mathematical models, with the Wang and Singh model, Verma et al. model, and Logarithmic model showing the best fit for each respective drying method. The natural convection method resulted in the highest color difference, while the solar drying method produced the highest hardness. Chlorogenic acid content increased with temperature during natural convection drying, while neochlorogenic acid concentration increased with temperature during forced convection drying. For solar drying, higher chlorogenic acid content was observed at 3 m/s, while higher neochlorogenic acid content was observed at 1 m/s.

Summary: This research work focused on the techno-economic process design of cellulose hydrogel synthesis from corncob biomass and analyzed their swelling and kinetic behaviors. Raw corncob was fractionated through alkali treatment to obtain cellulose fibers, which were then copolymerized with gelatin to produce cellulose hydrogel composite. The swelling efficiency of the cellulose hydrogel composite was investigated in different salt solutions and its drying kinetics were also studied. Techno-economic analysis estimated the operating cost and annual revenue for the hydrogel production process. The superior properties of the hydrogel make it a potential candidate for water retention and fertilizer releasing agent in agriculture.

Summary: The majority of the population in developing countries still relies on charcoal for energy needs. This study aims to determine the optimal temperature and moisture content for charcoal production using a fixed residence time. A vertical rectangular steel kiln with horizontal square stacking was selected for the experiment. Wood from Prosopis juliflora was subjected to pyrolysis process at different temperatures and moisture levels. The results showed that a residence time of 4 hours and a temperature of 500°C yielded the highest quality charcoal with a moisture content of 15.45%. An artificial neural network model was developed and evaluated for its accuracy in predicting charcoal production based on different training functions.

Summary: Due to growing ecological concerns and increasing energy consumption, biodiesel produced from nonedible and used cooking oils via transesterification is considered a clean and sustainable alternative to fossil fuels. The transesterification process leads to an excess of glycerol, which can be transformed into value-added derivatives like glycerol carbonate (GC) for industrial applications. Among various synthesis methods, the transesterification approach using dimethyl carbonate (DMC) is the most effective and environmentally friendly. This review focuses on diverse types of heterogeneous catalysts and characterization techniques used to identify and deactivate these catalysts, covering the literature from the last decade. The versatile applications of GC are briefly explained, and the review concludes with an outlook and the author's perspective.

Summary: This study examined the seasonal variation in the size of calanoid copepods in a tropical coast of India, and found that the size of copepods showed a clear seasonal pattern, with smaller size during summer months and larger sizes during the monsoon season. The size variation was negatively correlated with temperature, and positively correlated with dissolved oxygen, pH, salinity, and chlorophyll-a concentration. Certain species showed more pronounced changes in body size indicating species-specific responses to environmental fluctuations. These findings contribute to our understanding of the ecological processes and global warming that determine copepod size variation in coastal ecosystems.

Summary: This study investigated the impact of the non-antibiotic pharmaceutical carbamazepine on antibiotic resistance genes (ARGs) during anaerobic digestion. The results showed that carbamazepine induced the enrichment of ARGs and increased the abundance of bacteria carrying these genes. It also facilitated microbial aggregation and intercellular communication, leading to an increased frequency of ARGs transmission. Moreover, carbamazepine promoted the acquisition of ARGs by pathogens and elevated their overall abundance.

Summary: This paper developed a machine learning model to predict the biochemical methane potential during anaerobic digestion. Model analysis identified lignin content, organic loading, and nitrogen content as key attributes for methane production prediction. For feedstocks with high cellulose content, early methane production is lower but can be improved by prolonging digestion time. Moreover, lignin content exceeding a certain value significantly inhibits methane production.
