Grain size limit of nanocrystalline materials obtained by annealing glasses
A lower limit for the grain size of nanocrystalline solids obtained by crystallization of the glass and its dependency on the crystallization temperature are thermodynamically considered. It is found that the nanocrystalline materials have the smallest grain size when the crystallization temperature is roughly half of the melting temperature. At this temperature, the Gibbs free energy differenc...
متن کاملNanometer-Sized Electrochemical Sensors
Nanometer-sized glass-sealed metal ultramicroelectrodes (UMEs) have been prepared using a laser-based micropipet puller. The tip was exposed to solution either by etching away a small portion of glass insulator or by micropolishing. The characterization of the UMEs was carried out by a combination of steady-state voltammetry, scanning electron microscopy (SEM), and scanning electrochemical micr...
متن کاملElasticity of nanometer-sized objects
We initiate the development of a theory of the elasticity of nanoscale objects based upon new physical concepts which remain properly defined on the nanoscale. This theory provides a powerful way of understanding nanoscale elasticity in terms of local group contributions and gives insight into the breakdown of standard continuum relations. We also give two applications. In the first, we show ho...
متن کاملNanocrystalline materials and coatings
In recent years, near-nano (submicron) and nanostructured materials have attracted increasingly more attention from the materials community. Nanocrystalline materials are characterized by a microstructural length or grain size of up to about 100 nm. Materials having grain size of 0.1 to 0.3 mm are classified as submicron materials. Nanocrystalline materials exhibit various shapes or forms, and ...
متن کاملStresses in nanocrystalline materials
Thin film Ni-Cu diffusion couples (individual layer thicknesses: 50 nm) were prepared by direct-current magnetron sputtering on silicon substrates. Interdiffusion and solid-solution formation, the associated changes of microstructure and the evolution of mechanical stresses of the Ni-Cu diffusion couples during thermal treatments were investigated employing ex-situ X-ray diffraction phase and t...
