Chemical Recycle Turn turns silicone into pure building blocks and promising infinite reuse
A general strategy for chemical recycling of silicon polymers. Credit: nAm’cứcvũet al Research conducted by CNRS researchers explains new ways to recycle silicon waste (caulking, sealants, gels, adhesives, cosmetics, etc.). It could significantly reduce the environmental impact of the sector. This is the first universal recycling process that returns all kinds of spent silicon materials to their previous state in…

Iron and blue light allow for rapid and low toxic production of carbohydrates for new antibiotics
Credit: University of Oklahoma Researchers at the University of Oklahoma have found that could potentially revolutionize the treatment of antibiotic-resistant infections, cancer and other challenging Gram-negative pathogens without relying on precious metals. Currently, precious metals such as platinum and rhodium are used to create synthetic carbohydrates. It is an important ingredient in many approved antibiotics used to combat Gram-negative pathogens,…

From cages to sponge: Transform morphs of clathrate materials into powerful green hydrogen catalysts
The Ba8ni6ge40 is made up of polyhedral cages made of nickel (gray) and germanium (purple), each containing barium atoms. Credit: Hongyuan Yang/Hzb/Tub Clathrates are characterized by complex cage structures that also provide space for guest ions. Now, the team is the first to investigate the compatibility of clathrates as catalysts for electrolytic hydrogen production with impressive results. The clathrate samples…

Infrared spectroscopy with machine learning detects early wood coating degradation
Improve the sustainability of wooden buildings. Credit: (Kyoto/Whitney Havel) From Japanese cypress to ponderosa pine, wood has been used in construction for thousands of years. Materials such as steel and concrete have taken over the construction of large-scale buildings, but timber has been revived and is increasingly being used in public and multiple buildings due to environmental benefits. Of course,…
