Nanotechnology, in combination with surface engineering focused on a fabrication of various nanostructures and newmaterials, has recently attracted a vast amount of research attention, and has become a subject of intense scientific interest. Particularly, the inexpensive formation of periodically ordered structures (e.g., nanopore, nanotubes and nanowire arrays) with a periodicity lower than 100 nm, has triggered extensive activities in research. The present, huge progress in nanotechnology is a direct result of the modern trend towards the miniaturization of devices and the development of specific instrumentation that could visualize the nanoworld and allow surfaces to be studied at nanoscale resolution. Among various technologies that allow the visualization and characterization of nanomaterials and nanosystems, scanning probe microscopy (SPM) techniques and especially, scanning tunneling microscopy (STM) or atomic force microscopy (AFM), must definitely be quoted [1,2]. Recently, the basis of STM/AFM instrumentation, including a near-field imaging process and the use of piezoelectric actuators, has been successfully adapted to several techniques [3]. Consequently, scanning near-field optical microscopy (SNOM), photon scanning tunneling microscopy (PSTM), magnetic force microscopy (MFM) or scanning thermal profiling (STP) have begun to be used widely, not only for the surface imaging and characterization of materials in nanometer scale but also for providing additional information on surface properties [3]. The strong reduction of the dimensions and precise control of the surface geometry of nanostructured materials has resulted in the occurrence of novel and unique catalytic, electronic, magnetic, optoelectronic and mechanical properties. The unique properties of the nanostructure, or even of an integral functional unit consisting of multiple nanostructures, are the result of the collective behavior and interaction of a group of nano-elements acting together and producing responses of the system as a whole [4]. The potential of highly ordered nanomaterials for future technological applications lies mainly in the field of various nanophotonic, j1

A Review on Anodizing of Aerospace Aluminum Alloys for Corrosion Protection (2020, methodology): “Still, some authors report on completely amorphous anodic oxides and attribute the γ-Al2O3 percentage to an artefact caused by the interaction of the oxide layer with the electron beam during transmission electron microscopy [41,43,52].”
A review on the progress of polymer nanostructures with modulated morphologies and properties, using nanoporous AAO templates (2016, background): “Lee and coworkers [79, 105, 106] as well as Sulka and coworkers [107, 108] have demonstrated that pulse anodization enable a high control of pore diameter modulations in terms of shape and position.”
