Researchers present one-pot photothermal upcycling of polylactic acid to hydrogen and pyruvic acid

Plastic waste, a ubiquitous pollutant, poses a significant threat to both humans and the environment. However, it also represents a vast carbon resource. Recycling or upcycling plastic waste is not just a question of environmental sustainability but also a crucial step toward a circular economy. Plastic waste, a ubiquitous pollutant, poses a significant threat to both…

From lab to life: 3D bioprinting unveils new horizons in biomedical applications

With the development of intelligent biomedical engineering, the application of three-dimensional (3D) printing technology has become increasingly widespread. However, existing 3D printing technologies mainly focus on inorganic or polymer materials, limiting their applications in biocompatibility and biodegradability. Due to these challenges, there is a need for in-depth research on biocompatible and functional materials. With the development…
