A new book on nanotechnologies and nanomaterials
A new book on nanotechnologies and nanomaterials was recently published by Woodhead Publishing in UK, with two co-editors Prof. Ion Tiginyanu from Moldova and Prof. Abdel Makhlouf from Germany. Details related to the presentation of the monograph can be found at http://asm.md

In the Rapid Research Letter on p. 100, Mihai Enachi et al. demonstrate that anodization of Ti sheets in ethylene glycol and HF containing electrolyte leads to the formation of ordered arrays of double-walled TiO2 nanotubes. Interestingly, the inner diameter can be tuned in the range from 10 nm to 250 nm through the change of the electrolyte temperature while the outer nanotube diameter and the density of nanotubes remain temperature independent. The authors present evidence for the formation of a self-organized surface nucleation layer that is genetically connected to the outer nanotube shell at the origin of this phenomenon. These findings pave the way for manufacturing ordered arrays of TiO2 nanotubes with modulated inner diameter by a simple change of the electrolyte temperature.
