Recently, nanocrystalline cellulose was used as the filler phase in bio-based polymer matrices to produce nanocomposites with superior thermal and mechanical properties.
23.
In nanocrystalline solids, grain boundaries become a significant volume fraction of the material, with profound effects on such properties as diffusion and plasticity.
24.
Diamond hardness depends on its purity, crystalline perfection and orientation : hardness is higher for flawless, pure crystals oriented to the nanocrystalline diamond aggregates.
25.
As nanocrystalline silicon ( nc-Si ) has about the same bandgap as c-Si, nc-Si can replace c-Si.
26.
A hybrid magnesium cell using a mixed magnesium / sodium electrolyte with sodium insertion into a nanocrystalline iron ( II ) disulfide cathode was reported in 2015.
27.
Nanocrystalline materials have many interfaces between crystals, which Phonons are confined to the grain, if their mean free path is larger than the material grain size.
28.
In 1996 his group developed benzene-thermal synthetic method to nanocrystalline GaN . In 1998 they reported the preparation of diamond through pyrolysis process of catalytic reduction.
29.
Surface mechanical attrition treatment uses a process similar to shot peening, but with higher kinetic energy, to form a nanocrystalline layer on the surface of a metal.
