Helium is an element that we have gambled on for more than 100 years. The few sources of earth-based helium dictate that technological advances could make helium a cheap commodity.
Researchers from University College London (UK) developed a new paint which, when applied on surfaces, makes them superhydrophobic (very water repellant) and self-cleaning. Such surfaces are resistant to abrasion and handling; moreover, they maintain their properties even if contaminated with oil. These characteristics make them suitable for new everyday applications. Self-cleaning Surfaces Self-cleaning surfaces are […]
