Summary: This paper presents a simple method of impregnating a melamine sponge with deep eutectic solvents (DES) obtained from natural sources. The selected DES were found to have high sorption capacities, superhydrophobic and superoleophobic properties, low density, high porosity, and excellent stability. Furthermore, they can be regenerated multiple times without loss of sorption capacity. Therefore, DES-MS may serve as a green and low-cost alternative for removing oil from water.

Summary: Considering the serious damage caused by oil spills and oily wastewater discharge, the development of efficient, environment-friendly, and sustainable oil/water separation technology has become a necessary trend. Fabrics, with their degradability and low cost, are recognized as eco-friendly materials for water treatment. Fabrics with rough structures and natural hydrophilicity/oleophilicity enable the construction of superwetting surfaces, enabling the selective separation of oil/water mixtures and complex emulsions. This review systematically discusses the theory and mechanisms of special wettability, and highlights superwetting fabrics such as superhydrophobic/superoleophilic, superhydrophilic/superoleophobic, and Janus fabrics for efficient oil/water separation, as well as the challenges and future research directions in this field.

Summary: In this study, a light-responsive composite actuator was developed by combining inkjet-printed tissue paper with PNIPAM hydrogel. The mechanical property of the composite actuator was highly enhanced due to the high strength of tissue paper and the strong interaction within the interface of the bilayer structure. Furthermore, remote manipulation of light-responsive actuation was achieved using a stamping graphite electrode with high efficiency of photothermal conversion. Biomimetic actuating devices based on the near-infrared (NIR) light response of the composite actuator were also remotely controlled. This work provides a simple strategy for the construction of biomimetic anisotropic actuators and inspires the exploration of new intelligent materials.

Summary: Compared with traditional metal materials, carbon-based materials have the benefits of low density, high conductivity, and good chemical stability, making them reliable alternative materials in various fields. Among them, the carbon fiber conductive network created by electrospinning technology possesses high porosity, high specific surface area, and abundant heterogeneous interfaces. By using tantalum carbide (TaC) nanoparticles as conductive fillers, the crystallization degree, electrical and mechanical properties of electrospun TaC/C nanofibers were investigated at different temperatures. The best mechanical properties of 12.39 MPa were achieved at a carbonization temperature of 1200 degrees C. Through comprehensive analysis and comparison, it can be concluded that a carbonization temperature of 1200 degrees C is the optimum.

Summary: The leakage of gadolinium ions from commercial GBCAs is a safety concern in clinical MRI scans, and the lack of task-specific GBCAs limits their use in disease detection and imaging of specific biological regions. Ultrastable GBCAs were constructed by decorating chiral Gd-DOTA with a phenylic analogue, exhibiting high stability and outstanding inert nature. A hepatic-specific chiral Gd-DOTA was identified as a potential alternative to commercial Gd-EOB-DTPA, and combination with functional molecules favored its use as tumor targeting probes.
