A visible-light-driven postfunctionalization method developed by researchers from Japan enables the incorporation of phosphonate esters into polymers, expanding the possibilities for creating fire-resistant and temperature-responsive materials. This reaction technique offers a sustainable way to add useful functional groups to precursor polymer chains without altering their molecular weight, transforming common polymers into high-value materials that are difficult to obtain through direct polymerization of functional monomers.

Nowadays, plastic wastes have seriously endangered human health and ecological safety. Recycling plastics is a promising ap-proach to achieve multiple uses of carbon resources. In this review, photocatalysis is introduced for the conversion of plastics into various valuable chemicals. The state-of-the-art photocatalytic techniques for plastics conversion are divided into two categories of direct and indirect photoconversion. Researchers summarize in detail the photocatalytic small organic molecules conversion from polyeth-ylene terephthalate (PET), polylactic acid (PLA) and polyethylene (PE) through the alkaline-assistant and hydrothermal pretreat-ments. Then, they overview the effective strategies of direct photoconverting PE, PLA and polyvinyl chloride into chemicals via the two-step process, amination strategy, and single reactive oxygen species-assistant strategy. Finally, they present some outlooks of the current challenges and propose some potential solutions in the future.

Nanomaterials with catalytic properties that are derived from Chinese herbs are called ‘herbzymes’. Herbzymes are nanomaterials from Chinese herbs that mimic natural enzymes like peroxidase (POD), superoxide dismutase (SOD), catalase (CAT), and glutathione peroxidase (GPx). For a deeper understanding of herbzymes, researchers from China present a comprehensive review of different types of herbzymes and their mode of synthesis, while detailing their biomedical applications, current challenges faced, and potential directions for their development. 

Electronic implants are commonly used to diagnose and treat various diseases and to restore lost motor and sensory functions. Conductive hydrogels increase an implant’s electrical conductivity and flexibility within the body, improving the overall effectiveness of electronic implants. However, traditional electrically conductive hydrogels contain toxic additives that may have negative impacts on patients after long-term use. In a recent study published in Science Advances, researchers led by Dr. Limei Tian reported on a sweet solution to this problem: replacing these toxic additives with D-sorbitol, a safe sugar alternative commonly found in chewing gum.
