Ultra-thin camera lenses of the future could see the light of day

Thu, 06/11/2020 - 11:31
In the future, camera lenses could be thousands of times thinner and significantly less resource-intensive to manufacture. Researchers now present a new technology for making the artificial materials known as metasurfaces, which consist of a multitude of interacting nanoparticles that together can control light.

Puzzle about passivation of low-friction, hard carbon coatings solved

Wed, 06/10/2020 - 17:25
Diamond and diamond-like carbon reduce friction and wear in bearings and valves by means of so-called passivation layers, which prevent other materials from bonding to the coating. Until now, it was unclear how these passivation layers should be designed to achieve minimal friction.

A 'hole' lot of sponge! New technique to create super-sponges is a game changer

Wed, 06/10/2020 - 08:41
Metal-organic frameworks (MOFs) are sponge-like organic-inorganic hybrid materials and have a variety of uses due to their ultra-high porosity, or the ratio of pores or air pockets to the solid material. Through a technique called post-synthetic modification, researchers were able to enhance and modify the function of these materials for specific purposes.

Spontaneous formation of nanoscale hollow structures could boost battery storage

Tue, 06/09/2020 - 17:04
An unexpected property of nanometer-scale antimony crystals - the spontaneous formation of hollow structures - could help give the next generation of lithium ion batteries higher energy density without reducing battery lifetime. The reversibly hollowing structures could allow lithium ion batteries to hold more energy and therefore provide more power between charges.
