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: The hydrostability of boroxine-linked COFs (COF-1 as representative) was significantly enhanced by modification with tetraethylenepentamine (TEPA), which allowed the modified COF to survive in water and remain stable under humid conditions. The TEPA modification also greatly increased the CO2 adsorption capacity by 13 times and improved the CO2/N-2 selectivity in low pressure region, making the modified COF suitable for capturing CO2 from flue gas.

Summary: Two-dimensional (2D) nanomaterial-based membranes hold great promise for various applications due to their attractive properties in molecular separation and transport. However, the swelling problem of 2D membranes has hindered their performance. In this study, the insertion of flexible and hydrophilic carboxylated cellulose nanofibers (CNFs) effectively stabilized the Ti3C2Tx MXene laminar architecture, enhancing mechanical strength, fixing interlayer distance, and improving anti-swelling properties. Furthermore, the intercalation of nanocelluloses increased interlayer spacing and created open gaps for fast and selective molecular transport. When applied in antibiotics separative filtration process, the resulting membrane exhibited excellent anti-swelling properties and high selectivity of antibiotics, making it ideal for various applications.

Summary: Wearable strain sensors with conductive hydrogels have great potential in electronic skins and human-machine interfaces. However, the signal transmission of conductive hydrogels is unstable due to environmental humidity and inherent material shortcomings. In this study, a novel moisture-proof conductive hydrogel was developed by incorporating dopamine-functionalized gold nanoparticles into carboxymethyl guar gum and acrylamide, showing high toughness (2.89 MJ m-3), mechanical strength (1.00 MPa), and moisture-proof sensing performance. The hydrogel-based strain sensor can accurately monitor major and subtle human movements, demonstrating good sensitivity and repeatability. Moreover, the sensor exhibits stable sensing signals even after being left for 1 hour, with no noticeable noise signal under different strains (25-300%) at 99% relative humidity. Importantly, this wearable strain sensing technology is suitable for wearable sensor devices in high humidity environments.

Summary: CO2-responsive magnetic microspheres were prepared by enveloping Fe3O4 with SiO2 and grafting it on PDEA through ATRP technique, followed by molecular imprinting using PDA with BSA as a template. The microspheres showed good selectivity and reversibility in adsorbing BSA under CO2 stimulus. The interaction between BSA and PDEA was theoretically studied and the conformation of proteins remained unchanged under CO2 stimulus. This work provides a strategy to develop selective and switchable materials for protein recognition and separation.

Summary: In this study, a knitted PET patch was used as a nondegradable synthetic graft for bridging reconstruction of massive rotator cuff tears (MRCTs) in a rabbit model. The results showed that the PET patch not only provided mechanical support but also promoted enthesis and tendon regeneration. The PET group exhibited similar graft-bone interface scores as the autograft group, and had higher tendon maturing scores and improved collagen fiber organization. Thus, the knitted PET patch shows great promise as a graft option for MRCTs.

Summary: The interfaces in heterogeneous catalysts have a crucial role in their performances by providing active sites through synergistic effects or modulating the state of active sites. Constructing abundant interfaces in heterogeneous catalysts is challenging due to the high dispersion required for all catalyst compositions involved in substrate activation. A surface reduction strategy is proposed as a solution to this challenge, where a pyramid-type catalyst, (Pt/4nmCeO(2))/SiO2, with maximized interfacial Pt-CeO2 sites is created. This work aids in the development of heterogeneous catalysts by enabling a high level of control over the local chemical environment within nanomaterials.
