MOF-coated glass vials enable simple, reusable water contaminant testing

By Lisa McDonald / May 7, 2024

Metal-organic frameworks (MOFs) are an emerging material system for water treatment applications, but synthesizing these materials in bulk is challenging. Researchers from the University of La Laguna in Spain demonstrated a way to fabricate MOFs that not only stabilizes the material but also integrates it directly into glass vials for water contaminant testing.

Rinse and repeat: Water replaces toxic chemicals in printed electronics processing

By Lisa McDonald / February 9, 2024

Printable electronic inks and their associated print processes tend to rely on environmentally hazardous chemicals, which offsets the benefits of printed electronics in application. Engineers at Duke University developed a water-only printing process for fabricating printed electronics.

Solid-state electrocaloric materials heat up cooling performance

By Guest Contributor / January 19, 2024

Electrocaloric materials have potential to replace liquid refrigerant in cooling systems, thus avoiding the emission of harmful greenhouse gases. But currently, electrocaloric devices can only operate within a small temperature span. A recent study reported a new electrocaloric prototype with greatly improved temperature span and cooling power.
