Device to Attract and Trap Motile Aquatic Pathogens
The Caribbean region is considered a coral disease hotspot, with over 20 documented diseases and syndromes affecting over 20 species of corals. One motile marine pathogen family, Vibrionaceae, which is responsible for 50% of coral diseases, is strongly thermodependent, thus warming sea-surface temperatures, driven by pollution and global climate change,...

Functional Upcycling of Polyurethane Thermosets into Value-Added Thermoplastics by Small Molecule-Assisted Carbamate Exchange during Reactive Extrusion
Background Polyurethane (PU) is a widely used plastic material that has excellent physical and mechanical properties. However, PU is difficult to recycle due to its complex chemical structure, making the effective disposal of PU waste a pressing issue. Current methods for PU disposal include incineration, which can release harmful toxins into the environment,...

Coaxial Layered Fiber Spinning for Wind Turbine Blade Recycling
Background Plastic waste presents an acute environmental challenge to nearly all freshwater and marine ecosystems. The long degradation time of plastic requires effective methods of disposal to avoid adding additional plastic waste to aquatic environments. The end-of-life waste from wind turbine blades (WTBs) is also a pressing issue, as WTB waste...

Reprocessable Sorbents for Direct Air Capture of CO2
Background Negative emission technologies, including direct air capture (DAC), are a critical solution needed to reduce carbon emissions and lead to a net-zero scenario. DAC solutions are a viable solution that present many advantages, but generate increased demand for low-cost CO2 sorbents, due to greater amounts of material needed to effectively...

Electro-Regeneration of PFAS-Laden and Spent Sorbents for Reuse as Sustainable Water Treatment
Background Adsorption is the main water treatment technology that is commercially used to remove per- and polyfluoroalkyl substances (PFAS) from water. These substances are in thousands of everyday products due to their high stability and chemical resistance, but are non-biodegradable and can pose risks to human health. Current adsorption techniques...

Atomic Hydrogen Provision by Cobalt Sites for Superior Ammonia Production
Background Ammonia (NH3) is a valuable compound for industrial, agricultural, and water treatment applications. The typical method for large-scale production of ammonia is the Haber-Bosch (HB) process, which uses hydrogen and nitrogen as reagents under high pressure and temperature. However, this process generates over 450 million tons of CO2 annually,...
