Summary: Nowadays, there is a global shortage of fresh water, and utilizing adsorbent materials to extract water from the air is a suitable method for freshwater production. This research explores a new configuration for an adsorption desalination system using an evacuated tube collector (ETC) as an adsorbent bed, aiming to increase the temperature of the desorption process and thus produce more fresh water. The experimental results demonstrate the feasibility of this new system design.

Summary: An environmentally friendly adsorbent functionalized with L-cysteine was synthesized via sol-gel processing and effectively used for removing As(V) from aqueous media. The adsorbent exhibited enhanced As(V) uptake capacities with a maximum of 147.5 mg g(-1) at pH 3, reaching equilibrium within 120 min. The kinetic data followed a pseudo-second order model, while the isotherm data fitted well with the Freundlich model. The adsorbent showed a 23% decrease in removal capacity after 5 adsorption/desorption cycles. The presence of cysteine on the surface of the adsorbent was confirmed by solid state NMR and XPS techniques, and the efficient adsorption of As(V) was attributed to the formation of a bidentate complex between the AsO2(OH)(2)(-) anion and the NH3+ and carboxyl groups of L-cysteine. The results highlight the potential of SG-3PS-Cys in the treatment of As(V) in industrial wastewater discharges.

Summary: Novel spherically shaped organosilica materials with (propyl)ethylenediamine groups were synthesized using a modified one-pot Stober co-condensation method. The porosity of these materials was controlled by adding different silica monomers as structuring agents. The synthesized materials exhibited different sizes and mesoporosity depending on the amount of structuring silane used. The sorption capacities towards Cu(II), Ni(II), and Eu(III) ions varied depending on the porosity and spatial arrangement of the ethylenediamine groups.

Summary: This study demonstrated the effective adsorption of anionic azo dye NCC on PDADMAC modified silica and silica-gel in an aquatic environment. The removal efficiencies of NCC using PMS and PMSG were higher than 87%, indicating their potential as novel and reusable adsorbents for anionic dye removal. The electrostatic interaction between positively charged adsorbents' surfaces and negative sulfonic groups of NCC was identified as the main driving force for anionic azo dye adsorption onto PMS and PMGS adsorbents through analysis of adsorption isotherms and surface group changes.

Summary: Silica hollow microspheres were prepared as biocompatible cell carriers using emulsified gelatin microspheres as sacrificial templates. SEM observations showed their spherical morphology with a hollow structure and a diameter of 50-200 μm. FT-IR spectrum revealed the presence of Si-O-Si bonds. Gelatin microspheres served as supporting matrix and sacrificial templates for the formation of hollow structure. The silica hollow microspheres were found to be biocompatible and supported cell attachment and proliferation when seeded with osteoblast MC3T3-E1 cells, indicating their potential as biocompatible cell carriers.

Summary: The composite adsorption material ACF-silica sol-LiCl (ASL), prepared by impregnating activated carbon fiber (ACF) with silica sol and LiCl, is proven to enhance the water vapor adsorption performance of ACF. Silica sol solidifies the soft ACF and improves adhesion area for LiCl, which effectively increases the water vapor adsorption performance. The adsorption capacity of ASL steadily increases with relative pressure and exhibits higher dynamic water absorption rate and adsorption rate coefficient than ACF.

Summary: In this study, the influence of transition metal doping on the electronic and mechanical properties and electrochemical performance of 2HMoS2/NC was investigated using Cobalt (Co) as an example. Co doping was found to effectively improve the electronic conductivity and active site areas of 2H-MoS2/NC at different positions, optimizing the adsorption and diffusion capability of potassium ions. Furthermore, the study revealed the optimal roles of different types of nitrogen atoms in kinetic adsorption, diffusion, and interfacial stability of potassium ions. These findings provide guidance for the experimental design of high rate 2H-MoS2/NC electrode materials and the optimal design of other functional composite materials.

Summary: This research developed an effective approach to enhance the charging rates of lithium ion batteries (LIBs) by strategically incorporating carbon nanotube (CNT) conductivity boosters into Li4Ti5O12 (LTO) electrodes. Multi-layer architectures comprising CNT-rich and CNT-free LTO electrode layers were manufactured using a layer-by-layer spray coating method to promote charge transfer kinetics of high mass loading electrodes. The best performing multi-layer was paired with a spray-coated LiFePO4 (LFP) positive electrode, resulting in attractive power performance that outperformed conventional LTO || LFP combinations.

Summary: This study investigates the relationship between the morphology of PMMA monopolymers and PMMA-PHEMA copolymers with the expected nature of surfactant-free microemulsions (SFMEs) before polymerization. It is found that previously mesostructured, surfactant-free mixtures can produce porous polymers of different morphologies, while unstructured, oil-rich regions lead to solid, transparent polymers without nanostructured morphologies. Additionally, a surfactant-based reference system shows similar phase behavior and polymer morphologies as the comparable surfactant-free system, indicating the importance of the hydrotropic behavior of HEMA in this system.
