Study reveals final fate of levitating Leidenfrost droplets

Splash some water on a hot skillet, and you'll often see the droplets sizzle and quickly evaporate. But if you really crank up the heat, something different happens. The droplets stay intact, dancing and skittering over the ...

How to ice-proof the next generation of aircraft

35,000 feet is standard cruising altitude for a commercial jet airplane, but at those lofty heights the air temperature plummets below -51 degrees Celsius and ice can easily form on wings. To prevent ice formation and subsequent ...

Are we at the limits of measuring water-repellent surfaces?

How liquids are repelled by a surface, a property called "wettability," is important for engineers to develop aircraft that resist ice formation, for fashion designers developing outdoor gear that repels rain and dirt, and ...

Interactive surfaces enter a whole new dimension of flexibility

An "interactive surface" refers to an interface whose input and output share a common surface that can be manipulated intuitively with the fingers. However, ordinary multi-touch displays, e.g., liquid crystal displays (LCD), ...

New periodic table of droplets could help solve crimes

Liquid droplets assume complex shapes and behave in different ways, each with a distinct resonance—like a drum head or a violin string—depending on the intricate interrelationship of the liquid, the solid it lands on ...

Video: Flying under Aeolus

Following the launch of Aeolus on 22 August 2018, scientists have been busy fine-tuning and calibrating this latest Earth Explorer satellite. Aeolus carries a revolutionary instrument, which comprises a powerful laser, a ...

Collecting tiny droplets for biomedical analysis and beyond

In a single sneeze or a cough, as many as 40,000 tiny droplets are forcibly propelled from the mouth and nose into the air. Researchers from City University of Hong Kong (CityU) have recently developed a method to collect ...
