A DNA-based rewritable memory device

dnaDNA is well known as the genetic material, but has also been used as a building block for the construction of nanoscale structures and periodic arrays. One other application is the storage of information in DNA. Such an information storage method has many advantages including longevity and ability for highly dense storage, and is more suited for archival storage of data. In new work, scientists use shape-changing DNA nanostructures...

Structural engineering of 2D-layered energy materials

nanosheetsTwo-dimensional (2D) energy materials have outstanding physical and chemical properties in contrast to their bulk counterparts. This is particularly true for charge storage devices such as lithium-ion batteries and supercapacitors. Unfortunately, when directly applying these 2D nanostructured materials for energy storage, there is still a significant challenge as they may have serious self-restacking leading to decreased active...

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

nanograinSodium-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,...

A nanotechnology approach to augment nerve regeneration

neuronsIn recent years, researchers working in neurobiology have been intrigued by the idea of microtubule-stabilizing drugs as a therapy to augment nerve regeneration. In new work, scientists show that a better idea is to increase the amount of the dynamic parts of the microtubules. They do this by reducing the levels of fidgetin, a protein that normally exists in nerves to keep the dynamic parts of microtubules from elongating...
