Summary: Environmental and process parameters were evaluated for the sorption of ciprofloxacin and acetaminophen onto banana peel biochars. The biochars prepared at 750 degrees Celsius showed maximum pharmaceutical sorption. Relationships between biochar properties and sorptive potential were positively correlated with surface area, total pore volume, %C, %ash and C/N molar ratios.

Summary: This study evaluated the application of deep eutectic solvents (DESs) for the extraction of phenolic compounds from pineapple peels and their antioxidant capacity. The results showed that using a DES (choline chloride-glycerol) as the extraction solvent resulted in a higher concentration of phenolic compounds compared to traditional solvents. The antioxidant capacity of the extract was also found to be high. The study also optimized the process variables to further enhance the quality of the extract.

Summary: This study evaluated the functional and volatile compounds in the extracts of MD pineapple peel and core. The results showed that the peel had lower total soluble solids, pH, titratable acidity, sweetness index, and astringency index compared to the core. The peel also had higher total phenolic and flavonoid contents, better antioxidant activity, and a higher concentration of certain volatile compounds. These findings provide important insights into the valorization of MD pineapple waste.

Summary: The drying kinetics of two pineapple varieties at different temperatures were determined and the characteristics of residual peel flours were characterized. The increase in temperature resulted in an increase in the diffusion coefficient and a reduction in drying time. The Midilli model provided the best fit to the drying process. The pineapple flours had good characteristics for conservation and had high nutritional value.

Summary: This study investigated the mechanisms of interactions between N-acyl homoserine lactones (AHLs) and two maize straw-derived biochars (MBs) with different pyrolysis temperatures. It was found that biochar had the ability to adsorb AHLs, with higher sorption capacity observed in biochar pyrolyzed at 600 degrees C. The findings suggest that biochar can be specially prepared to mediate soil processes related to microbial communication.

Summary: This study used delignified pineapple peel to isolate lignocellulose nanocrystals (LCNC) and found that controlling the delignification process can adjust the properties of LCNC such as morphology, crystallinity, hydrophobicity, and rheological behavior. The presence of lignin in LCNC was confirmed through various spectroscopic techniques, and regulating the delignification process can influence the average length, diameter, crystallinity, and hydrophobicity of the obtained LCNC, as well as the performance of the stabilized Pickering emulsions. This work demonstrates that the properties of LCNC can be controlled by adjusting the delignification degree, which is significant for the high value utilization of lignocellulosic agricultural waste.

Summary: In this study, the enzymatic properties and composition of bromelain extracts from pineapple core and pulp were compared to explore the feasibility of recovering bioactive bromelain from pineapple core. The results showed significant differences in protein content between the two preparations, but no significant differences in proteolytic activity and the effect of pH on enzymatic activity. Mass spectrometry analysis confirmed the presence of the same peptidases in the fruit and core, indicating the feasibility of obtaining large amounts of bioactive bromelain from pineapple core, thus laying the foundation for implementing a circular economy in this specific industry.

Summary: Supercapacitors (SCs) based on hierarchical nanoporous framework composite materials and aqueous electrolytes have recently attracted the attention of researchers. A facile composite of UiO-66 modified with pineapple peel derived activated carbon (PA-AC) was developed, exhibiting a high specific capacitance of 295.9 F g(-1) at 2A g(-1). The UiO-66/PA-AC//UiO-66/PA-AC symmetrical SC delivered a maximum energy density of 29.6 Wh kg(-1) at a power density of 170 W kg(-1). This study highlights the potential importance of incorporating MOFs into pores of biowaste derived carbon to enhance the charge storage kinetics of moderately conducting MOFs.

Summary: This study evaluated the valorisation of agricultural waste materials by transforming them into biochar for water treatment in aquaculture. Coconut husk biochar prepared at 750 degrees C was found to be the most effective sorbent material for removing organic micropollutants from surface water. Ionic strength had a significant impact on sorption, with high salinity decreasing sorption for certain antibiotics but increasing sorption for other pollutants, which should be considered in coastal aquaculture applications.

Summary: The NH4+-modified biochar showed higher sorption affinity for norfloxacin (NOR) and sulfamerazine (SMR) compared to the raw biochar, while the raw biochar exhibited higher sorption affinity for oxytetracycline (OTC). OTC had the highest sorption to both biochars, followed by NOR and SMR. Additionally, electrostatic interactions among the ionic antibiotics in the multicomponent solution increased NOR and SMR sorption to both biochars.

Summary: This study used ultrahigh-resolution mass spectrometry to identify and assess DOM molecules in 45 lakes across China. The results showed that the variations in DOM chemical composition were mainly influenced by the hydrology and nutrient concentrations of the lakes, with some influence from human activities. Environmental factors mainly affected DOM chemodiversity through S-containing compounds, and N-containing compounds showed a positive correlation with CO2 emissions while N- and S-free compounds showed a positive correlation with N2O emissions.

Summary: This study investigated the effects of eco-corona formation on the reactivity of two-dimensional transition metal dichalcogenide (TMDC) nanomaterials and their ecological risk. The presence of extracellular polymeric substances (EPS) as the eco-corona constituents resulted in lattice distortion and the formation of defects on the TMDC material. Moreover, the EPS-corona induced higher generation of free radicals by the TMDC material. The TMDC-EPS exhibited stronger developmental inhibition, oxidative stress, membrane damage, photosynthetic toxicity, and metabolic perturbation effects on algae. However, the entry of TMDC into the algae through endocytosis pathways was inhibited by EPS. Metabolic and transcriptomic analyses revealed the downregulation of fatty acid metabolism and genes related to photosynthesis as the mechanisms underlying the enhanced toxicity of TMDC-EPS. The findings of this study provide mechanistic insights into the transformation and phytotoxicity of TMDCs in the presence of EPS, which are valuable for environmental safety assessments and sustainable applications of engineered nanomaterials.

Summary: Economic levels are strongly correlated with microbial diversity in lakes, with bacterial diversity decreasing and fungal diversity increasing with higher economic levels. Human activities significantly alter the composition of microbial communities in lakes, with bacteria being more susceptible to anthropogenic disturbances than fungi. Air quality, urbanization, ozone, and fisheries have negative impacts on bacterial and fungal diversity in lakes.

Summary: In this study, an advanced oxidation process using electrolysis coupled with peroxymonosulfate (E/PMS) was used to improve the dewaterability of waste activated sludge (WAS). The results showed that the E/PMS process significantly reduced the water content and capillary suction time of the sludge, indicating improved dewaterability. The generation of reactive oxygen species in the process damaged the extracellular polymeric substances (EPS) and reduced the viscosity of the sludge, leading to a decrease in sludge volume and improved disposal efficiency. Additionally, the E/PMS treatment also enhanced the degradation of organic matter and reduced the toxicity and bioavailability of heavy metals in the sludge.
