Low pressure reduces bubble trouble

Spray coating and inkjet-based electronics manufacture are among the industrial applications in which liquid droplets are applied to a surface. But minuscule air bubbles that get trapped beneath the droplet as it lands can ...

Viruses—lots of them—are falling from the sky

An astonishing number of viruses are circulating around the Earth's atmosphere – and falling from it – according to new research from scientists in Canada, Spain and the U.S.

Simulating splash at the microscopic level

Spray cooling is one of the most promising methods for cooling high heat flow electronics. Two-phase spray cooling, in particular, has been shown to cool heat fluxes that are orders of magnitude higher than traditional cooling ...

Sea spray losing its sparkle?

Atmospheric aerosols are tiny particles that scatter and absorb sunlight but also influence climate indirectly through their role in cloud formation. One of the largest sources of aerosols is sea spray which is produced over ...

A tool to protect police dogs in drug raids from overdosing

Police dogs simply follow their noses to sniff out narcotics. But inhaling powerful opioids can be deadly, so officers have a new tool to protect their four-legged partners: naloxone, a drug that has already been used for ...

How plankton and bacteria shape ocean spray

As the oceans ebb and flow, the resulting waves and splashes form tiny bubbles. The bubbles burst and release a vapor—called sea spray aerosol—into the air. This aerosol scatters sunlight and is involved in forming clouds ...

Researchers create touchpads with a can of spray paint

Touch sensing is most common on small, flat surfaces such as smartphone or tablet screens. Researchers at Carnegie Mellon University, however, can turn surfaces of a wide variety of shapes and sizes into touchpads using tools ...
