Dancing droplets' new spin on water harvesting
A more efficient way to capture fresh water from the air could be inspired by a phenomenon of motion first glimpsed in bowls of breakfast cereal.

The water in the air originates from both natural and forced evaporation, with condensation being the final and crucial step in water harvesting. Condensation involves nucleation, growth, and shedding of water droplets, which ...
In chemistry, structure is everything. Compounds with the same chemical formula can have different properties depending on the arrangement of the molecules they're made of. And compounds with a different chemical formula ...
When an electric vehicle accelerates, the motor generates maximum forces and enormous pressures act on the gears of the electric drivetrain. Surface meets surface, metal meets metal. If there were no lubricating film to allow ...
Researchers have developed a new mechanism to make water droplets slip off surfaces, and describe it in a paper published in Nature Chemistry. The discovery challenges existing ideas about friction between solid surfaces ...
The friction on a graphene surface can be dynamically tuned using external electric fields, according to researchers at the University of Illinois Urbana-Champaign led by Professor Rosa Espinosa-Marzal of the Department of ...
In early 2023, the German village of Lützerath was the site of violent clashes between thousands of protesters and police who wanted to clear the village so it could be swallowed up by Garzweiler II, a huge opencast coal ...
Underwater "traffic" encompasses a fascinating variety of creatures, from fish with their graceful swimming postures to jet-propelled jellyfish and remoras hitching rides on other organisms. Among these, a remarkable species ...
Separating molecules is critical to producing many essential products. For example, in petroleum refining, the hydrocarbons—chemical compounds composed of hydrogens and carbons—in crude oil are separated into gasoline, ...
The whaling industry helped drive industrialization in the 19th century, with whale oil used to light lamps and lubricate machinery. Even after petroleum replaced whale oil as an energy source in the U.S., whaling continued ...
