Ultrafast quantum information processing in nanostructured semiconductors

Superlattices and Microstructures, 2002
We shall review two implementation proposals for quantum information processing based on charge degrees of freedom in semiconductor nanostructures. An all-optical implementation scheme using semiconductor macroatoms/molecules will be discussed. The computational degrees of freedom in this proposal are interband optical transitions driven by ultrafast ...

Iron-based 1D nanostructures by electrospinning process

Nanotechnology, 2010
Iron-based 1D nanostructures have been successfully prepared using an electrospinning technique and varying the pyrolysis atmospheres. Hematite (Fe(2)O(3)) nanotubes and polycrystalline Fe(3)C nanofibers were obtained by simple air or mixed gas (H(2), Ar) annealing treatments.

Chemical Processing of Nanostructured Materials

MRS Proceedings, 2001
ABSTRACTNanocrystalline ( particle diameter less than 50 nm) ceramic powders have been prepared by the rapid evaporation of precursor solutions containing the respective metal nitrates/ hydroxides, triethanolamine (TEA) and sucrose in stoichiometric amounts. Complete evaporation of the solutions yields a fluffy dried precursor mass.

Magnetisation Processes in Magnetic Nanostructures

1999
At present there is great interest in magnetism on the nano-scale which covers magnetic behaviour which can be characterised on a length scale of nanometres (10-9m) [1,2]. Additionally artificial structures can be created in which at least one of the dimensions is on the nanometre scale.

Processing of nanostructured zirconia ceramics

Nanostructured Materials, 1995
The inert gas condensation (IGC) technique was employed to synthesize nonagglomerated nanoparticles of ZrO 2 2 and Y 2 O 3 with different average particle sizes ranging from 4 to 14 nm. High pressure phases were found in the as-prepared powders of both n-Y 2 O 3 and n-ZrO 2 . This has been explained on the basis of Gibbs-Thomson effect. The sintering

Natural and Processed Food Nanostructures

2017
In Chinese culture, the lotus flower is recognized as a symbol of a notable man since its leaves rise immaculately clean from the mud. This effect has now been recognized to be the result of the presence of nanostructures and the hydrophobic properties of lotus leaves.

Solution processed Al-doped ZnO nanostructures

2010 International Conference on Nanoscience and Nanotechnology, 2010
We report the wet-chemical synthesis of Al-doped ZnO thin films, powders, and nanorod arrays. Solid state 27Al NMR studies on powder samples confirm the incorporation of the Al ions in the tetrahedral Zn sites in the structure. The degree of Al incorporation is dependent on the amine type used in the precursor solution and the heating profile prior to ...

Quantum information processing using semiconductor nanostructures

Physica B: Condensed Matter, 2002
Abstract We shall review two implementation proposals for quantum information processing based on charge degrees-of-freedom in semiconductor nanostructures. An all-optical implementation scheme using semiconductor macroatoms/molecules will be discussed.

Deformation processing of massive nanostructured materials

International Journal of Materials Research, 2007
Abstract Deformation processing of initially polycrystalline material can lead to ultrafine-grained or even to nanocrystalline material, depending on the applied deformation route. In addition to different grain sizes, materials processed by different deformation methods also display different thermal stabilities. In order to analyze the

Chemical Processing of Nanostructured Coatings

2000
Nanostructured materials, often characterized by a physical dimension of 1-100 mn (such as grain size) and significant amount of surfaces and interfaces, have been attracting much interest because of their demonstrated or anticipated unique properties compared to the conventional materials (1-3).
