The ultralow friction between atomic layers of hexagonal MoS2, an important solid lubricant and additive of lubricating oil, is thought to be responsible for its excellent lubricating performances. However, the […]
High-precision metal cutting is increasingly relevant in advanced applications. Such precision normally requires a cutting feed in the micron or even sub-micron dimension scale, which raises questions about applicability of […]
A new method has been developed to precisely cut and to sharpen carbon nanotubes using a “nanoknife”, which is a short carbon nanotube adhered to a metal tip. The mechanism […]
