Copper(ii)-catalyzed hydrolysis system for recycling biodegradable PLA and PHA films
A water-based catalytic process that uses a copper(II)-amine complex to depolymerize biodegradable PLA and PHA films into reusable monomers. The catalyst is recyclable via CO2 precipitation, offering a low-cost, sustaina...
Polyvinyl alcohol nanofibers for VOC absorption and pathogen elimination in air filtration
Electrospun polyvinyl alcohol nanofibers designed to absorb volatile organic compounds and eliminate pathogens. Compatible with existing HEPA filtration systems, the high-surface-area material can be loaded with catalyst...
Natural mineral filtration system for selective removal of targeted organics from coconut water
A combinatorial screening approach using natural mineral crystals to selectively remove oxygen-containing organics, benzothiazoles, and carboxylates from coconut water. Leverages hydrogen bonding, host-guest chemistry, a...
Real-time powder x-ray diffraction for automated zinc scrap detection
This technology uses real-time powder X-ray diffraction to distinguish zinc-coated from uncoated steel scrap, enabling automated sorting in recycling. It identifies zinc's crystalline phases without sample prep, optimizi...
