For decades, chemical engineers have dreamed of a material that combines the strength and durability of metal with the crystal-clear purity of glass. Such a "clear metal" could be used to construct towering glass-walled skyscrapers that require less internal support. Aluminium oxynitride or AlON is a ceramic composed of aluminium, oxygen and nitrogen. AlON is optically transparent (?80%)
Photovoltaic Glass (PV glass) is a technology that enables the conversion of light into electricity. To do so, the glass incorporates transparent semiconductor-based photovoltaic cells, which are also known as solar cells. The cells are sandwiched between two sheets of glass. Photovoltaic glass is not perfectly transparent but allows some of the available light through. it provides the same thermal and sound insulation, and natural light as a conventional architectural glass.
Researchers are fitting people’s heads with ultrasound-emitting helmets to treat tremors and Alzheimer’s. They’re using it to remotely activate cancer-fighting immune cells. Startups are designing swallowable capsules and ultrasonically vibrating enemas to shoot drugs into the bloodstream. One company is even using the shockwaves to heal wounds
