Properties of Nanostructured Materials

Furthermore, this technique allows variation of the grain size [30-33] this is important because many chemical and physical properties of nanostructured materials depend on the grain size. Only by variation of the crystallite size - this is a novd aspect in materials sdence and technology [34] - is it possible to tune and hopefully improve certain physical properties of one and the same material for example, the enhanced hardness of nano-Au, the toughness of nano-Ni/P alloys [35], the soft magnetic properties of nano-Ni [36] and the resistance of nanostructured materials [37, 38] promise industrial applications [39-41],... 

X-ray diffraction technique is a non-destructive analytical technique that reveals information about crystallographic structure, chemical composition and physical properties of nanostructured materials. UV/Vis spectroscopy is routinely used in the quantitative determination of films of nanostructured metal oxides. The size, shape (nanocomb and nanorods etc,) and arrangement of the nanoparticles can be observed through transmission electron microscope (TEM) studies. Surface morphology of nanostructured metal oxides can be observed in atomic force microscopy (AFM) and scanning electron microscopy (SEM) studies. 

Nanomaterials energy and applications As nanocrystals and nanotubes are better understood, it becomes possible to rationally design nano-structured materials for specific purposes. This area includes both chemical synthesis and physical properties of nanostructured materials incorporating fullerenes, organic conductive polymers, and inorganic nanostructures. A central goal is composite materials for solar energy utilization—new types of solar cells. 

In addition to improved methods for controlling the structure and composition of semiconductors, there is emerging work in the field of nanophotonics that may be favorably exploited for use in water photoelectrolysis. Much of the work in nanophotonics seeks to manipulate photons using the properties of nanostructured materials in ways that cannot be achieved with macroscopic optical components.

In both cases the electrodes were intentionally made very thin, without binders or conductive additives, so that the intrinsic properties of nanostructured materials could be measured. Electrode substrates were prepared by first roughening the surface of the stainless steel plates (to be used as the spacers in 2016 coin cell) using 400 grit sandpaper. A thin nickel/copper coating ( 100 nm) was then evaporated on the surface and finally, the silicon/germanium was deposited directly onto the metal-coated planar substrate.
