Nissan’s new paint cools cars by up to 21 °F in direct sunlight

Nissan has demonstrated a new automotive paint that can drastically cool a vehicle parked in direct sunshine. Tests have shown that treated cars stay up to 21.6 °F (12 °C) cooler than untreated cars parked side by side.Continue ReadingCategory: Materia… Continue reading Nissan’s new paint cools cars by up to 21 °F in direct sunlight

More transparent than glass, new material cools rooms and self-cleans

Having lots of glass surfaces can brighten up a room, but it also lets in too much heat as well as neighbors’ prying eyes. A new metamaterial is not only more transparent to light, but adds privacy, cools the room inside, and automatically cleans itsel… Continue reading More transparent than glass, new material cools rooms and self-cleans

Harvard’s bizarre “metafluid” packs programmable properties

Harvard engineers have created a strange new “metafluid” – a liquid that can be programmed to change properties, like its compressibility, transparency, viscosity and even whether it’s Newtonian or not.Continue ReadingCategory: Materials, ScienceTags: … Continue reading Harvard’s bizarre “metafluid” packs programmable properties

3D-printed titanium lattice is 50% stronger than WE54 aerospace alloy

A new type of 3D-printed lattice structure has surprised researchers with its strength and light weight. It uses two different lattice structures merged together to eliminate the weak points normally found in these complex shapes.Continue ReadingCatego… Continue reading 3D-printed titanium lattice is 50% stronger than WE54 aerospace alloy

Vibrantly colored film could massively passively cool cars and buildings

It’s common knowledge that lighter colors reflect more light than darker ones, which can limit the practical palette choices for your clothes, car or house in a warming world. Now, scientists have developed a new material, inspired by butterfly wings, … Continue reading Vibrantly colored film could massively passively cool cars and buildings

Ultrasound metasurfaces move large objects without touching them

Engineers at the University of Minnesota have developed a new system that can move objects without making physical contact. The technique involves ultrasound waves acting on specialized surfaces to push or even pull objects in different directions, whi… Continue reading Ultrasound metasurfaces move large objects without touching them

Nanopillared lenses let scientists trap individual atoms with light

“Optical tweezers” – systems that focus light to trap and manipulate individual atoms – could pave the way for powerful quantum devices, but they can be a little cumbersome. Researchers have now developed a simplified, smaller design for optical tweeze… Continue reading Nanopillared lenses let scientists trap individual atoms with light

Microscopic metavehicles are pushed and steered by light

Although solar-powered devices are now fairly common, Swedish scientists have created something a little different. They’ve built tiny “metavehicles” that are mechanically propelled and guided via waves of light.Continue ReadingCategory: ScienceTags: L… Continue reading Microscopic metavehicles are pushed and steered by light
