In the world of materials science, perovskite oxides are like the superheroes of energy conversion. They have a special power: they can conduct both ions and electrons. This makes them perfect for solid oxide fuel cell (SOFC) cathodes. But there's a catch. Most of these materials have a crystal stru
The quest to make hydrogen peroxide (H2O2) through electrochemistry is tough. It needs a stable and high-performing electrode-electrolyte interface. A recent breakthrough used glucose to tweak the environment around this interface. This was done by sticking glucose onto graphite felt. The result? A
Picture this: you're trying to balance a seesaw, but one side is super heavy, and the other is super light. That's the challenge scientists face with zinc-air batteries. The key is to balance two important processes: oxygen reduction and oxygen evolution reactions. These reactions happen when the ba
Imagine powering your car or home with nothing but water and air. That's the promise of proton exchange membrane fuel cells (PEMFCs). But to make this a reality, scientists need to find a way to make a crucial process called oxygen reduction reaction (ORR) happen more efficiently in acidic environme
You might think that making batteries is just about throwing some chemicals together. But scientists are getting really clever about it! They’re mixing carbon nanotubes and graphene to make special composites. These composites have nitrogen (N) and sulfur (S) added in just the right way to make zinc
