One-step CO₂ system triples capture, ditches silver for zinc, and turns emissions into industrial fuel feedstock

Every year, power plants and factories release billions of tons of carbon dioxide (CO₂) into the atmosphere. Methods exist to capture that CO₂ using chemical solutions and, separately, to convert pure CO₂ into useful fuels ...

'Like liquid metal': Entangled, staple-like particles could inspire new generation of materials

A tightly packed ball of office staples can be surprisingly strong. Try to pull it apart and the tangled metal resists like a solid object. But with the right movement or vibration, that same bundle can quickly fall back ...

Oxygen anchoring unlocks air-stable solid-state batteries with faster charging

Expectations are rising for all-solid-state batteries—the "dream battery" with low fire risk—not only for electric vehicles but also for various fields such as robotics and Urban Air Mobility (UAM). A research team at KAIST ...

Depleted oil fields offer hydrogen storage sites

Hydrogen is a clean-burning gas that could help to tackle climate change by reducing our dependence on fossil fuels. But storing and transporting hydrogen is expensive and technically challenging, typically requiring high-pressure ...

Bridges, roadways threatened by changes in weather patterns

The combination of extreme weather conditions, like atmospheric rivers, and aging infrastructure is putting increasing pressures on Canadian highways, bridges and tunnels—many of which are almost 100 years old. UBC Okanagan ...
