Summary: In this study, a superhydrophobic-superoleophilic polyvinyl alcohol sponge modified by stearic acid/nano-TiO2 particles was constructed for oil-water separation. The sponge showed a water contact angle of 163 degrees, a water sliding angle of less than 3 degrees, and an oil contact angle of 0 degrees. The modified sponge could adsorb 5-8 times more oil than its own mass and maintain the oil sorption capacity even after being reused for 5 times.

Summary: This study focuses on the development of environmentally friendly and chemically recyclable thermosets using renewable based monomers, TGPh and THPMTGE. The thermosets were prepared by crosslinking the monomers with HMPA or methyl nadic anhydride, and showed lower reaction temperatures, higher crosslinking densities, and compact networks. Tensile tests demonstrated their remarkable mechanical properties, and they exhibited complete dissolution at a temperature of 170 degrees C, making them a viable alternative to non-recyclable and toxic resins in high-end industrial applications.

Summary: In recent years, as non-biodegradable single-use plastic packaging products have been restricted, paper-based materials have gained attention for their environmental benefits. However, the hydrophilic nature of paper-based materials limits their use as replacements for non-biodegradable plastics. In this study, a superhydrophobic paper was developed using silane-modified nanofibrillated cellulose, which showed excellent water repellency, durability, and antibacterial properties. This durable and multifunctional superhydrophobic paper provides a novel solution to reduce white pollution and opens up new possibilities for the applications of paper-based materials.

Summary: Frequent oil spills have a significant impact on ecological balance. Traditional superhydrophobic materials are limited to organic solvent separation and lack the ability to undergo thermal conversion. Photothermal materials, utilizing solar energy as a constant power source, have emerged as promising, environmentally friendly, and cost-effective solutions. This study presents the self-assembly of titanium nitride/polydopamine nanoparticles on polyurethane sponges and subsequent coating with polydimethylsiloxane. The material demonstrates excellent photothermal conversion efficiency, stability, and adhesion, making it suitable for continuous separation of crude oil/seawater in oceanic environments.

Summary: An environmentally friendly and durable Mg0.5-xCuxZn0.5Fe2O4 (x = 0, 0.01 & 0.02) nano-photocatalyst was prepared using a facile solution combustion method for the efficient photocatalytic removal of carbamazepine. The Cu-doped catalyst exhibited a degradation rate of 94.3% under visible light exposure for 90 minutes, with a 78.2% removal of total organic carbon (TOC). The introduction of Cu dopants led to a shift in the conduction band to promote the formation of O-2(-) radicals, enhancing the photocatalytic activity.

Summary: This experimental study investigated the performance of self-compacting concrete (SCC) by partially replacing natural sand and ordinary Portland cement (OPC) with manufactured sand (M-sand) and fly ash (FA) respectively. The optimal replacement levels were determined to be 50% for N-sand by M-sand and 20% for OPC by FA. The results showed that the use of FA and M-sand improved the environmental-friendliness and durability of concrete, as well as enhanced its performance in a sulphate environment.

Summary: This study focused on the semihydrogenation of acetylene in an ethylene-rich stream using two alloyed Pt catalysts PtCu and PtCo. The PtCu catalyst showed higher activity and ethylene yield compared to PtCo due to its higher unoccupied Pt d-orbital density. This indicates that alloying Pt with Cu is more promising for industrial relevant SHA catalyst.

Summary: This work presents a continuous solvent extraction method for the separation of cobalt and nickel in a millifluidic system using Cyphos IL 101 (C101) as the extractant. The optimal conditions for extraction performance and solvent properties were determined by investigating the effects of channel length, flow rate, and temperature. The performance of a developed manifold structure was compared to a single-channel system, and excellent separation results were achieved. The continuous separation process using the manifold structure resulted in high purity cobalt and nickel 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.
