Nanoparticles

Metal nanoparticles (NPs) provide optical, magnetic, and electronic properties which are different from the corresponding bulk metal materials, leading to photothermal, therapeutic, and electronic device applications, respectively. Recent research efforts have explored NPs having complex compositions with controllable sizes and morphologies. Special attention has been given to metal NPs for use as optical materials (i.e.,…

Metal nanoparticles (NPs) nowadays represent the key material in vast range of industrial applications ranging from rough industry to fine medical or biochemical utilization. Gold and silver NPs and their applications are currently of great interest. In recent years, rapid developments in nanotechnology have evolved to the point where inclusion of those entities into smart…

SEMICONDUCTING NANOWIRES Based on the geometry, 1D nanostructures typically consist of four categories: nanowire (NW), nanorod (NR), nanobelt (NB), and nanotube. The first three categories all possess a solid structure, while the nanotube has a hollow center. There is a significant different in geometry, property, and synthesis strategies between the nanotube and the first three…

Size- and shape-controlled synthesis of self-organized, three-dimensional (3D) micro/nano architectures are still challenging and much attracted in the recent years owing to vast scientific and technological interest in multifaceted research areas [11, 27, 14]. The growth and development of uniform, self-aggregated 3D super-structures through plane-to-plane coalition of the basic building blocks have been paid significant attention owing…

Titanium dioxide (TiO2), a semiconducting material, is a well-known photocatalyst [1-5]. Examples of previous studies about TiO2 photocatalytic reactions are listed in Table 1. A nanoparticle (NP) of TiO2also demonstrates photocatalytic activity. Important applications of TiO2 photocatalysts are bactericidal activity [2-4, 6-12] and degradation of chemical pollutants [2-4, 13]. Related physical and chemical mechanisms have been also investigated [2-5, 14-17]. Photo-irradiated…

Modern nanotechnology includes several promising areas such as nano-optics, nano-photonics, nanochemistry, nanobiology, and nanomedicine. During the past decade, we have witnessed a tremendous growth of nanoparticle applications that require particles of different materials with different size, dispersion, shape, and morphology. As a result, the development of new nanoparticle synthesis methods is particularly important. Among the…
