Abstract Over the past decade, much progress has been made in the application of multifunctional membranes with special wettability for the separation of oil–water mixtures. This progress has been driven by frequent oil spill accidents and oily wastewater, which are enormous threats to the vulnerable aquatic environment. The design of permeable superwettable membranes for oil–water separation has been inspired by the development of highly wetting/nonwetting interfaces, but these membranes are su

A superhydrophobic carbon nanofiber network inlay-gated mesh with high durability and separation performance was developed for oil–water emulsion separation.

Plastic is produced, used, and accumulated exponentially. Humans can take it through the food chain, and microplastics can be potentially toxic to humans. In this study, we analyzed the surface patterns of microplastics and their effects on humans using polyvinyl chloride (PVC) and acrylonitrile butadiene styrene (ABS). The surface analysis of these microplastics will be used as a standardized measurement method for microplastic detection and will be used as an indicator of the impact of environ

Edible scaffolds are needed in cultured meat to mimic meat's three-dimensional structure by organizing cells and replenishing the insufficient meat mass of cells alone. However, there is still a large gap between slaughtered meat and cells developed into tissues using scaffolds. This is mainly due to the difference in size, texture, flavor, and taste. In this study, we develop a coating matrix to modify the surface of textured vegetable protein (TVP), a vegetable cell support, to produce culture

Clear overlay appliances (COAs) are widely used in orthodontic fields because they offer many advantages, such as cost-effectiveness, good formability, and good optical characteristics. However, it is necessary to frequently replace COAs because the thermoplastic polymers that are used to fabricate COAs have poor abrasion resistance and have a tendency to induce bacterial accumulation. Here, we have developed polysaccharide-based antibacterial multilayer films with enhanced durability, intended

Many studies of drug delivery nanoplatforms have explored drug loading affinity and controlled release. The nanoplatforms can be influenced by their inherent building blocks. Natural polypeptide silk fibroin (SF) is an excellent nanoplatform material because of its high biocompatibility and unique structural properties. SF secondary structures have different properties that can be changed by external stimuli. Thus, the characterization of SF-containing platforms is strongly affected by secondary

This study investigates a highly flexible/stretchable and mechanically durable superhydrophobic/superoleophilic coating for efficient oil/water separation and oil absorption. The coating is applied via a simple immersion process using a mixed solution of a biocompatible adhesive (ethyl cyanoacrylate, ECA), a highly stretchable polymer (polycaprolactone, PCL), and superhydrophobic/superoleophilic nanoparticles (fluorine-coated silica nanoparticles, F-SiO₂ NPs) in a solvent, followed by

Nitric oxide (NO) plays a key role in several physiological functions such as inflammatory responses and immune regulation. However, despite its beneficial functions, the short half-life and diffusion radius limit NO availability in biomedical applications. Hence, controlled release is important to achieve the desired therapeutic effects with exogenous NO delivery. In this study, we fabricated a poly(lactic-co-glycolic acid) (PLGA)-based NO delivery system to release NO in a sustained manner und
