Expandable foam for 3-D printing large objects

It's a frustrating limitation of 3-D printing: Printed objects must be smaller than the machine making them. Huge machines are impractical for printing large parts because they take up too much space and require excessive ...

Space age for metals, foams and the living

Astronauts donned gloves on the International Space Station to kick off two European experiments on metals and foams, while preparing spacesuits for future work outside their home in space.

Image: Space foam already bubbling as planned

Installed on Friday in the International Space Station and sending down images by Monday. This picture shows one of the first images of foam formed inside the Fluid Science Laboratory in Europe's space laboratory Columbus.

Another fluid experiment joins long running research on foam stability on the International Space Station. The Foam-Coarsening experiment, developed by Airbus for ESA, is scheduled to be activated this month in the Fluid ...

Intelligently recovering and recycling balsa wood

There are 30,000 wind turbines in operation in Germany, many of which are starting to age. In 2019, 2000 rotor blades had to be discarded; in 2024, this figure will shoot up to 15,000. But where to put these up to 90-meter-long, ...

Women firefighters face high exposure to toxic PFAS chemicals

San Francisco's women firefighters are exposed to higher levels of certain toxic PFAS chemicals than women working in downtown San Francisco offices, shows a new study led by researchers at the University of California, Berkeley, ...

Bubble-capturing surface helps get rid of foam

In many industrial processes, such as in bioreactors that produce fuels or pharmaceuticals, foam can get in the way. Frothy bubbles can take up a lot of space, limiting the volume available for making the product and sometimes ...
