Summary: A new aminophosphonate extractant, di(2-ethylhexyl) (N, N'-di(2-ethylhexyl) amino methyl) phosphonate (L), was synthesized and used for the extraction and separation of gallium and indium from chloride solution. The maximum separation factors SFGa/In reached 995, higher than those of its analogues Cextrant 230 (SFGa/In = 471) and BEADP (SFGa/In = 201) under optimal acidity conditions. The extracted complexes were identified as HGaCl4L2 and InCl3L2. The extraction reactions of gallium and indium were both endothermic. The loading capacities of 30 vol% L for Ga and In were 32.9 g/L and 25.2 g/L, respectively. Gallium and indium loaded in the organic phase can be effectively stripped by distilled water, H2SO4, and HNO3. A process was developed for the separation and purification of gallium, with Ga2O3 purity increasing from 98.4% to 99.97% and a yield of 92.5%.

Summary: This work proposes a simple approach to address the challenge of metallization in highly integrated (3D) stretchable electronics. Eutectic gallium indium (EGaIn) is an attractive conductor for stretchable electronics, but its high surface tension makes sub-micrometer patterning challenging. This limitation is overcome by electrodeposition, a bottom-up approach that benefits from the resolution of mature nanofabrication methods. A record-high integration of EGaIn lines of 300 nm half-pitch is achieved. Moreover, vertical integration is enabled, leading to omnidirectionally stretchable 3D electronics.

Summary: This article reviews the electromechanical responses of EGaIn in stretchable electronics and investigates pure EGaIn using three electrical resistance measurement techniques. The results show significant differences in measured electromechanical behavior between the three methods, which can be explained by correcting for a fixed offset in the measurement circuits. However, even with these corrections, the average relative change in resistance of EGaIn is found to be lower than predicted by the commonly used bulk conductor assumption.

Summary: Recent studies have shown that electrochemical oxidation can significantly decrease the interfacial tension of liquid metals, from approximately 500 mN m(-1) at 0 V to approximately 0 mN m(-1) at less than 1 V. This reversible and controllable change in tension surpasses what is achievable through conventional electrocapillarity or surfactants. The report aims to introduce beginners to this field, clarify misconceptions, and discuss applications and future challenges related to modulating the interfacial tension of liquid metals.

Summary: As the wearable heater becomes increasingly popular, there is a need to improve its tensile stability. However, maintaining stability and precise control of heating in these heaters remains challenging due to multiaxial dynamic deformation with human motion. In this study, a pattern study for a circuit control system was proposed, which showed the significance of input power per unit area for steady average temperature with tension. A wearable heater with minimal resistance change regardless of tension direction was developed using Peano curves and sinuous pattern structure, and it demonstrated stable heating in actual motion.

Summary: Casein hydrolysate (Pep) is found to be a dispersant for poorly water-soluble drugs and nutraceutical ingredients, forming two types of complexes based on permeability: hydrocolloids and non-hydrocolloids. The size and hydrophobicity of the molecules in the complexes determine their permeability, with pH values also affecting the permeability of certain complexes. Stoichiometry and association constants for complexes can be determined using fluorescence quenching method.

Summary: This study focuses on the recovery of sinapic acid using liquid-liquid extraction assisted by a hollow fiber membrane contactor from an aqueous feed obtained through the hydrolysis of mustard bran. The screening of solvents of different chemical nature showed that all tested solvents had an extraction efficiency of more than 80% for pH < 5. Four solvents were selected for use in the hollow fiber membrane contactor, and the volatile solvents showed higher mass transfer coefficients compared to non-volatile solvents. The extraction efficiency was intensified by increasing the initial concentration of sinapic acid and the feed-to-solvent ratio. CPME was found to have optimal recovery efficiency at a phase ratio of 8:1, yielding 0.9 g of sinapic acid per liter of CPME used.

Summary: In this study, a nanofibrous layered structure of Ff-Ti3C2Tx-Co3O4 was prepared by self-assembling nanofibrous Co3O4 with lamellar fluorine-free MXene (Ff-Ti3C2Tx). The Ff-Ti3C2Tx-Co3O4 exhibited excellent catalytic activity for degradation, resistant to ionic interference, and maintained high removal efficiency of sulfamethoxazole (SMX) in municipal wastewater. The rapid SMX degradation involved fast electron transfer in redox cycles with PMS and the generation of 1O2 via PMS ->center dot O2 -> 1O2. This work provides new insights into antibiotic degradation mechanisms and electron transfer based on PMS activation.

Summary: In this study, sludge-derived biochar (SBC) was functionalized with various iron salts to enhance its adsorption ability for sulfamethoxazole (SMX) and magnetic collection performance. Ball milling was further employed to treat the optimal iron salt functionalized SBC (MSBC), resulting in ball milled SBC (BMSBC) with improved adsorption performance for SMX. The dominant driving mechanism for SMX adsorption onto BMSBC was confirmed to be multiple physicochemical forces, including 7C-7C conjugation, pore filling, H-bonding, Fe-O complexation, and electrostatic interactions. BMSBC exhibited favorable adsorption ability for SMX in actual waters and could be easily collected within 1 min due to its magnetic sensitivity.
