Several structural engineering strategies are applied to develop innovative templates based on nanoporous anodic alumina. These templates are subsequently used to develop other nanostructures based on certain materials with multiple applications such as polymers, magnetic metals and semiconductors. These replicated nanostructures could be integrated in various types of nanodevices (e.g. nanoelectrodes for direct deposition of nanoparticles from a gas draught, bulk-heterojunction solar cells, one-dimensional optoelectronic devices, nanofilters and so on). It is expected that the results presented will become a starting point to develop new nanodevices and applications in a wide range of research fields.

Cadmium Sulfide (CdS) nanostructures are attractive for applications in semiconductor lasers, light emitting diodes, photovoltaic cells and display devices. The present report is concerned with the growth and characteristics of CdS nanostructures for possible applications in charge storage, nano-capacitor, photovoltaic and photosensing devices. The fabrication of hexagonal, well-arranged porous alumina templates and the growth of CdS nanowires in the templates are discussed. The characteristics of needle- and wire-like CdS nanocomposites grown in a polymer matrix are analyzed. The nanocomposite/conducting polymer device exhibits negative resistance and charge storage characteristics. MWCNT-CdS nanostructures embedded in a conducting polymer shows a broad spectral response (400-1000nm), which is attractive for hybrid photovoltaic devices. The growth of core-shell Ge/CdS radial nanowire heterostructures by a combination of vapor-liquid-solid growth and chemical process is reported. The photodiode behavior of Ge/CdS heterojunction and enhancement of photocurrent with a broadband response from visible to near-IR due to the formation radial heterojunctions are discussed in details.

ggf. zzgl. Versand

Self-assembled peptide nanostructures present a vast potential for materials science. These nanostructures are formed by self-assembly of small molecular weight molecules. Programmed assembly of peptides can be achieved by providing certain inputs at the design level. Noncovalent interactions such as electrostatic interactions, hydrogen bonding, pi-pi interactions, solvophobic effects and van der Waals forces can be used as inputs determining fate of a supramolecular ensemble. Supramolecular ensembles can be used as functional templates for the synthesis of hybrid organic-inorganic and purely inorganic nanomaterials. Peptide nanostructures can be utilized in patterning of organic materials as well. For instance, encapsulation of chromophore molecules in peptide nanostructures presents an interesting approach in controlling photophysical properties of enclosed molecules. Peptide nanostructures have shown great versatility and applicability in materials science. This fact is not surprising, because numerous phenomena taking place in nature actively exploit polypeptides as a handy tool in materials synthesis and its hierarchical organization.

Recent contamination of food by the use of melamine has led to huge economic losses in the food industry. Food and drug administration (FDA) currently uses methods that are laborious and time consuming. As a consequence scientists have been grappling with development of methods that are more efficient and cost effective for trace analysis of various food adulterates. One such method is the use of silver nanostructures in the presence of Surface Enhanced Raman spectroscopy that are capable of generating high enhancement of the signals, leading to low detection of the signals from the analyte. In the book, a literature review of the various synthesis methods, purification of the end products,assembly of nanostructures on glass templates as well as characterization of silver nanowires/nanoparticles and their potential use in Surface Enhanced Raman Spectroscopy is suggested.
