Superconductivity has fascinated scientists for many years since it offers the potential to revolutionize current technologies. Materials only become superconductors — meaning that electrons can travel in them with no resistance — at very low temperatures. These days, this unique zero resistance superconductivity is commonly found in a number of technologies, such as magnetic resonance
Perovskite solar cells promise cheaper and efficient solar energy, with enormous potential for commercialization. But even though they have been shown to achieve over 22{261f6ead6a0f3cabae584e9904bae8bd53a3c91c6c837aa2d58453541104ad2d} power-conversion efficiency, their operational stability still fails market requirements. Despite a number of proposed solutions in fabrication technology, this issue has continued to undercut whatever incremental increases in efficiency have
Drones are designed to fly, but crashes are a fact of life, whether because of external forces or pilot error. Some commercial drones employ techniques like propeller guards to at least protect the drone, or humans nearby, but they’re not exactly effective all the time. More industrially-inclined drones even have “cages” that protect them but
