Synthesis of 2D metal oxides and hydroxides - high-yield, efficient, fast and low-cost

NanoWerk.com - Fri, 06/23/2017 - 11:32
As two-dimensional (2D) materials gain more and more importance - thanks to their exotic electronic properties and abundant active sites - the development of high-yield, efficient, fast and low-cost synthesis methods to advance these materials from the laboratory to industry has become an urgent issue. Now, researchers have developed a general and rapid molten salts method that can synthesize various ion-intercalated 2D metal oxides and hydroxides, such as cation-intercalated manganese oxides, cation-intercalated tungsten oxides, and anion-intercalated metal hydroxides.

Holey pattern boosts coherence of nanomechanical membrane vibrations

ScienceDaily.com: Nanotechnology News - Thu, 06/22/2017 - 18:38
Researchers have introduced a new type of nanomechanical resonator, in which a pattern of holes localizes vibrations to a small region in a 30 nm thick membrane. The pattern dramatically suppresses coupling to random fluctuations in the environment, boosting the vibrations' coherence. The researchers' quantitative understanding and numerical models provide a versatile blueprint for ultracoherent nanomechanical devices. Among others, this enables a new generation of nanomechanical sensors to probe quantum limits of mechanical measurements, and more sensitive force microscopy.
