Scientists have found a clever way to make solar hydrogen production more efficient. They created a special photoanode using indium oxide and selenium. This combo boosts the photoanode's ability to capture and use sunlight. The selenium in the photoanode creates tiny flaws, called oxygen vacancies.
Picture this: tiny gaps in a material that were once seen as a major issue. These are hydrogen vacancies in metal-halide perovskites, which are used to make solar cells. For a long time, scientists believed these vacancies caused a lot of energy loss as heat, instead of converting it into electricit
Tin dioxide (SnO2) gas sensors have been with us for a long time, yet their inner workings are still shrouded in mystery. This lack of understanding makes it hard to improve these sensors. Scientists have been working to figure out how these sensors function. A major breakthrough came when research
An interesting thing about lithium-ion batteries is how tiny oxygen holes can boost power. Imagine something really small—that's an oxygen vacancy. These vacancies are missing oxygen atoms in a material. When researchers looked closely at a material called Cu2Nb34O87-x/N-doped carbon composite, they
