Five unusual technologies for harvesting water in dry areas

Water scarcity is among the top five global risks affecting people's wellbeing. In water-scarce areas, the situation is grim. Conventional sources like snowfall, rainfall, river runoff and easily accessible groundwater are ...

Eliminating microplastics in wastewater directly at the source

A research team from the Institut national de la recherche scientifique (INRS) has developed a process for the electrolytic treatment of wastewater that degrades microplastics at the source. The results of this research have ...

Nanoengineered cement shows promise for sealing leaky gas wells

Leaking natural gas wells are considered a potential source of methane emissions, and a new nanomaterial cement mixture could provide an effective, affordable solution for sealing these wells, according to a team of Penn ...

Physicists create 3-D printed microboat

From prow to stern, this little boat measures 30 micrometers, about a third of the thickness of a hair. It has been 3-D-printed by Leiden physicists Rachel Doherty, Daniela Kraft and colleagues.

Revising climate models with new aerosol field data

Smoke from the many wildfires burning in the West have made air quality hazardous for millions of people in the United States. And it is the very tiniest of the aerosol particles in that air that make it particularly harmful ...

Climate: Iodic acid influences cloud formation at the North Pole

The Arctic is warming two or three times faster than the rest of the planet. This amplified warming is due to several factors, but the relative importance of each one remains still unclear. "We do know, however, that clouds ...

The realization of active microscale Marangoni surfers

Marangoni surfers are small particles that self-propel while straddling a fluid-fluid interface in a way similar to that in which a surfer moves on the surface of a wave. In recent years, self-propelling particles have become ...
