Summary: In this study, a simple method was used to design a porous composite of expanded graphite (EG)/polyvinylidene fluoride (PVDF), which exhibits good flexibility, mechanical strength, and electrostatic dissipation properties. The electrical conductivity of the composite significantly improves, while the electrical resistivity and volume resistivity decrease by increasing the concentration of EG. The mechanical testing shows that the Young's modulus of the composite increases with the addition of EG. Thermogravimetric analysis reveals an enhanced maximum degradation rate for the EG composite compared to pure PVDF.

Summary: In this study, a method of Fe-modified water treatment residues (Fe-WTR) was proposed to enhance the removal efficiency of fluoride (F-) from water. The maximum adsorption capacities of WTR and Fe-WTR for F- were determined, and the kinetics and mechanism of F- adsorption by Fe-WTR were investigated. Fe-WTR exhibited excellent resistance to interference from coexisting anions and pH changes, making it suitable for various environmental applications. This study provides deeper insights into the F-removal mechanism by WTR and offers potential for future modifications of WTR for effective water treatment.

Summary: In this study, cellulose nanofibers (CNFs) and citric acid were used to prepare a new type of porous foam material, and the effects of citric acid content and heat treatment on the foam properties were investigated. The results showed that increasing the citric acid content slightly enlarged the pore size and reduced the activation energy for cellulose thermal decomposition in the foam. Heat treatment only significantly affected the release rate of cellulose. The mechanical behavior of the foam changed after wetting. The foam exhibited a two-step mechanism for chromium adsorption and had suitable water resistance for applications as an adsorbent in aqueous media.

Summary: Recently, mild acid hydrolysis has been proposed as a novel method to transform biomass into bioplastics. However, the alkaline hydrolysis of plant residues has not been studied for this purpose. In this study, a comprehensive comparative analysis was conducted on the physicochemical, thermal, mechanical, and morphological properties of bioplastics produced by acid and alkaline hydrolysis from two different plant residues. The results showed that the alkaline hydrolysis produced bioplastics with superior mechanical and barrier properties compared to the acid hydrolyzed biomass.

Summary: Due to legislation, long-chain PFASs must be reduced and replaced with short-chain PFASs, which results in the abrupt introduction of short-chain PFASs in the environment. This study explores the use of a chitosan/polyethyleneimine based composite xerogel for the removal of PFBS from water. The study finds that the maximum PFBS adsorption capacity of the xerogel is 305 mg/g within 24 hours, and the adsorption process involves electrostatic interactions and hydrogen bond formations.

Summary: In this study, agar-based hydrogels incorporating different concentrations of orange peel particles and 1.5 wt% limonene were developed as active soil conditioners for agriculture. The results showed that acid hydrolysis or ultrasonication pretreatments of orange peel were counterproductive, and the simplest method of pretreatment resulted in the most efficient hydrogels in terms of swelling. The incorporation of limonene increased the swelling capacity of the hydrogels in tap water, while the incorporation of orange peel particles did not significantly influence their swelling capacity.

Summary: In this study, polycarbonate (PC) nanoplastics (NPs) were formed by laser ablation of solid PC films in water, with the size of the particles depending on the laser energy fluence. The NPs were found to be composed of PC with highly oxidized surface, similar to PC fragments from natural photo-degradation. Additionally, the study revealed cytotoxic effects of the NPs on human hepatocytes, as well as reduction in albumin production, which were attributed to both the NPs and the photo-degradation by-products.

Summary: The use of machine learning to predict the performance of specific adsorbents in phosphate adsorption shows great promise in saving time and revealing underlying mechanisms. However, the small size of the dataset and insufficient detailed information limits the model training process and the accuracy of results. To address this, the study employs a fuzzing strategy that replaces detailed numeric information with descriptive text messages on the physiochemical properties of adsorbents. This strategy allows the recovery of discarded samples with limited information, leading to accurate prediction of adsorption amount, capacity, and kinetics. The study also finds that phosphate uptake by adsorbents is generally through physisorption, with some involvement of chemisorption. The framework established in this study provides a practical approach for quickly predicting phosphate adsorption performance in urgent scenarios, using easily accessible information.
