In the case of spin coatings [16, 148], it provides uniform thin films to flat substrates. The substrate is rotated at high speed in order to spread the coating materials by centrifugal force. This method is suitable for the preparation of thin …
The major use of the conventional ball milling is to fracture the particles and to reduce the size, which is different from the newly established high energy ball milling (HEBM) method. In this new method a magnet is placed close to the cell to apply a strong magnetic pulling force on the magnetic milling balls, and therefore the impact energy is much higher than the …
A series of SnO 2 –Co 3 O 4 thick films containing 0– Co 3 O 4 in mass were prepared from the component oxides through mixing by ball-milling for 24 h, screen- and sintering at 700 C for 3 h. The composite films were found to exhibit n- or p-type response to CO and H 2 depending on the Co 3 O 4 contents in the composites.

In this chapter, we present an overview of synthesis of MgO nanoparticles and thin films by using top-down and bottom-up approaches. The bottom-up approaches are generally utilized to grow nanoparticles by the methods that involve chemical reactions. Sometimes, methods based on these reactions are also able to grow thin films. The top-down approaches …

It is a method that can even be used to deposit a nano-thin film directly on to a nanoparticle, and this is a variation known as particle ALD. ALD uses two precursor materials to build a nanofilm. Where ALD differs from other CVD methods is that the different precursors are never present within the reaction chamber at the same time—they are deposited sequentially.
The synthesis of metal nanocomposites includes spray pyrolysis, liquid infiltration, the rapid solidification process, high-energy ball milling, chemical vapor deposition, physical vapor deposition, and chemical processes—sol-gel and colloidal.

Novel nano-periodic structured BaTiO 3 films prepared by a sol–gel template synthesis using a through-hole-type AAO template film. The nano-periodic structure was drastically modified from a liquid-bridge-like structure to nanotube arrays by incorporating a spray-cleaning step with 2-methoxyethanol during spin-coating of the template.

Microwave techniques eliminate the use of high temperature calcination for extended periods of time and allow for fast, reproducible synthesis of crystalline metal oxide nano materials. Utilizing microwave energy for the thermal treatment generally leads to a very fine particle in the nano crystalline regime because of the shorter synthesis time and a highly focused local heating.
After ball milling to form a nano ink, and then spin coating, SEM images proved the generation of CZTO precursors which effectively promoted the formation of Cu2ZnSnS4 thin films. Finally, the phase, microstructure, chemical composition and optical properties of the Cu2ZnSnS4 thin films prepared by sulfurized annealing CZTO precursors were …
