“…These undetached SiNTs are something like undetached alumina nanotubes in porous alumina membrane. Alumina nanotubes can be easily detached from membrane by ultrasound vibration [28]. Therefore, we may adopt similar experiments to get individual SiNTs.…”

“…Recently, many research groups [97][98][99] have been investigating the deposition of carbon nanotubes with controlled sizes, using chemical vapor synthesis (CVD) in a porous alumina template. Yanagishita et al [100] prepared carbon nanotubes using porous alumina with triangular pores as template; these templates were prepared according to the procedure reported by Masuda et al [72].…”

The visualization and/or handling of atom clusters, or even individual atoms, has been achieved during the past 25 years. One of the most practical instruments for this purpose is the tunneling microscope, which was invented during the 1980s. On such a small scale, materials properties are not the same as those of a macroscopicsized substance. The first occasion on which a scientist proposed atom handling was in 1959, when Professor Richard Feynman [1], during a lecture at the California Institute Technology, suggested that in the near future engineers would be able to take atoms and place them exactly where they wanted to, without -of courseinfringing the laws of Nature. Today, Professor Feynmans lecture, which was entitled There is Plenty of Room at the Bottom, is considered a milestone of the current technological and scientific era.We can define nanoscience as the study of the phenomena and handling of structures on the atomic, molecular and macromolecular scale, where at least one dimension is significantly less than the others. And nanotechnology includes the design, characterization, and production of devices and systems on a nanometer scale. This definition of nanotechnology is wide-ranging, it is not a specific technology, all of the techniques based on physics, chemistry, biology, materials science and engineering -and/or using computers -leading to the development of materials and tools in such a way that the common point among them is the reduced dimension in which they operate. Among these applications are: increased storage and processing capacity for computers; the creation of new mechanisms for drug delivery; and the production of materials which are both lighter and more resistant than metals and plastics. Additional benefits of nanotechnology developments include energy saving, environmental protection, and the more efficient use of increasingly scarce raw materials.Today, these new investigations into material fabrication are focused mainly on nanostructured devices or, at least, microdevices.

“…Studies of replication using engineering materials such as metal, ceramic and polymer with a nanohoneycombed, porous anodic alumina template have been performed in the last decade [33][34][35][36][37][38][39][40][41][42][43][44][45]. Dipping has been widely used as a polymer coating method because of its simplicity [46,47].…”

A surface was created with the same superhydrophobic property as the lotus leaf (lotus effect) by dipping of sandblasted porous alumina into polytetrafluoroethylene (PTFE, Teflon R : DuPont TM ) solution. The fabricated engineered lotus leaf had PTFE dual-scale structures. This fabrication process has several advantages, including low fabrication cost, simplicity and easy coverage of a large area. The sandblasted porous alumina template was fabricated by sandblasting of an aluminum sheet and anodization in oxalic acid. To obtain PTFE dual-scale structures, PTFE replication based on the dipping method was used, with a 0.3 w% PTFE solution. To remove the aluminum and alumina layers, wet etching by chromic and phosphoric acid mixed solution and liquid HgCl 2 solution was used. The fabricated surface has a superhydrophobic property whose apparent contact angle of the PTFE dual-scale structures was approximately 165 • and sliding angle is less than 2 • .
