Alkaline earth metal vanadates: new anode materials for high performance sodium-ion batteries

Nanowerk.com - 12 сентября, 2017 - 10:43
Sodium-ion battery, as an emerging battery technology beyond lithium-ion battery, has attracted great research interests recent years. Sodium-ion batteries have a similar configuration and electrochemical reaction processes with lithium-ion batteries. But the Na resources are much more abundant and cost-effective than Li resources, which makes sodium-ion batteries highly promising as next-generation energy storage devices, especially for large-scale energy storage. However, the practical application of Na-ion batteries is still not currently realized.

Assembling colloidal matter with an opto-thermophoretic strategy (w/video)

Nanowerk.com - 11 сентября, 2017 - 15:08
Researchers have developed various assembly approaches, including self-assembly and electric/magnetic field directed assembly, to build diverse colloidal matters. These techniques feature high throughput but with limited structural configurations. Specifically, some of the techniques highly rely on the physical performance of the colloidal particles. In new work, researchers have developed a versatile colloidal assembly strategy - termed opto-thermophoretic assembly (OTA) - to build artificial colloidal matter in a wide range of colloidal materials, sizes, and shape.

Spraying light - the fabrication of light-emitting 3D objects

Nanowerk.com - 9 сентября, 2017 - 11:36
The light-emitting electrochemical cell (LEC) shares several external attributes with the OLED, notably the opportunity for soft areal emission from thin-film devices, but its unique electrochemical operation eliminates the principal requirement on inert-atmosphere/vacuum processing as it can comprise solely air-stabile materials. This important intrinsic advantage has inspired recent work on an ambient-air fabrication of LEC devices using scalable means. Introducing a new, purpose-designed spray-sintering deposition technique, researchers have now shown that it is possible to spray out liquid inks onto essentially any surface for the achievement of light emission.
