Wastewater is commonly contaminated with many pharmaceutical pollutants, so an efficient purification method is required for their removal from wastewater. In this regard, an innovative tertiary Se/SnO@CMC/Fe-GA nanocomposite was synthesized through encapsulation of metal organic frameworks (Fe-glutaric acid) onto Se/SnO-embedded-sodium carboxy methyl cellulose matrix to thoroughly evaluate its effectiveness for adsorption of levofloxacin drug from wastewater. The prepared Se/SnO@CMC/Fe-GA nanocomposite was analyzed via UV-Vis spectroscopy, Fourier-transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), thermo gravimetric analysis (TGA), energy dispersive X-ray (EDX), and X-ray diffraction (XRD) to valuate optical property, size, morphology, thermal stability, and chemical composition.

Miniaturization of next-generation active neural implants requires novel micro-packaging solutions that can maintain their long-term coating performance in the body. This work presents two thin-film coatings and evaluates their biostability and in vivo performance over a 7-month animal study. To evaluate the coatings on representative surfaces, two silicon microchips with different surface microtopography are used.

Strategies for combining ionic and non-ionic functional groups are important for altering detergent properties and exploring new chemical spaces within the detergentome. Previous synthesis protocols for ionic/non-ionic hybrid detergents require asymmetric detergent precursors with independently addressable hydroxyl groups that can be decorated with charged groups. However, preparation of ionic/non-ionic headgroups can be tedious in terms of required synthesis steps and resource consumption.

Hydrogel-based flexible electronic devices have garnered significant attention due to their excellent mechanical properties, high electrical conductivity, and signal sensitivity. Nevertheless, internal water molecules crystallize inevitably at low temperatures, impairing the performance of hydrogels. Designing anti-freezing and tough hydrogels to meet long-term stability requirements is extremely challenging.

Hydrogel electrolytes are crucial for solving the problems of random zinc dendrite growth, hydrogen evolution reactions, and uncontrollable passivation. However, their complex fabrication processes pose challenges to achieving large-scale production with excellent mechanical properties required to withstand multiple cycles of mechanical loads while maintaining high electrochemical performance needed for the new-generation flexible zinc-ion batteries. Herein, we present a superspreading-based strategy to produce robust hydrogel electrolytes consisting of polyvinyl alcohol, sodium alginate and sodium acetate.
