Summary: Polysaccharides and proteins are essential macromolecules for biomedical hydrogels. Chemical hydrogels, which have chemical bonds mediated by crosslinkers, offer better chemical, mechanical, and dimensional stability compared to physical hydrogels. This review revisits the crosslinking reactions between synthetic or natural crosslinkers and polysaccharides or proteins. It discusses the mechanisms, evaluation methods, and challenges in creating safe chemical hydrogels for biomedical applications.

Summary: Oily wastewater discharge from industrial activities and oil spills has had a significant impact on human health and the global environment. Membrane separation is a promising solution for oily wastewater treatment, and this study successfully prepared a novel membrane by combining fibrous MXene nano-ribbons with mixed cellulose. The resulting MCE-MNRs membrane exhibited outstanding oil-water separation performance, with high water permeance and over 99% rejection rates for various oil-water mixtures. The membrane's excellent performance is attributed to the formation of a water layer during filtration, which allows water to pass through freely but blocks oil droplets.

Summary: The search for higher-quality nanomaterials for medicinal applications is ongoing. Electrospun fibers, which have similarities with natural tissues, have made significant progress in medical applications. Combining nanoparticles and nanofibers in composite materials allows for additional functions, such as photothermal, magnetic response, biosensing, antibacterial, drug delivery, and biosensing. There are two primary ways to prepare nanofiber and nanoparticle hybrids (NNHs): through single-step electrospinning or through the self-assembly technique. This paper focuses on the application of NNHs in drug release, antibacterial effects, and tissue engineering, utilizing biocompatible polymer composites.

Summary: In recent years, various industries have released wastewater with high concentrations of dyes directly into the ecological system, causing severe pollution. Activated carbon has been proven to be an efficient technology for removing dyes from wastewater, but its high cost has prompted researchers to explore alternative, more economical adsorbents derived from bio-waste. This review critically evaluates the characteristics of bio-waste-derived adsorbents, the parameters influencing their performance, and discusses regeneration processes, economic challenges, and the utilization of post-sorption materials.
