As fluids approach their critical points, large molecular clusters are formed and as a result, the physical properties such as the specific heat and compressibility diverge. A variety of nanostructures are formed via self-assembly near the critical points. I show carbon onions, coils, fibres and other interesting structures created in near-critical carbon dioxide, ethane, xenon, benzene and their mixtures. (b) Structures and dynamics of clusters composed of magnetic particles: Various structures are formed by magnetic particles via anisotropic dipole-dipole interactions. The cluster structures and dynamics can be actively controlled by external magnetic fields such as dc, ac and rotational ones. I show self-organised structures and dynamics of clusters composed of ferromagnetic and superparamagnetic particles. (c) Application of cluster dynamics to the development of bio-medical devices: Biomolecules and cells can be labelled by magnetic particles and CNTs and therefore can be manipulated and sorted quite easily by applying external magnetic fields. Biomolecules and cells can also be manipulated utilising the magnetic hole effect, in which case labelling is not necessary. I explain a new nano/micro technology for a quick detection of diseases and allergies utilising the interactions between magnetic particles/CNTs and biomolecules/cells in external magnetic fields.","PeriodicalId":6354,"journal":{"name":"2010 International Conference on Enabling Science and Nanotechnology (ESciNano)","volume":"25 1","pages":"1-1"},"PeriodicalIF":0.0,"publicationDate":"2010-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84343552","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The Kerr type of light in the nonlinear microring resonator (NMRR) induces the chaotic behavior. In this proposed system chaotic signals are generated by an optical soliton or Gaussian pulse within a NMRR system. The parameters, such as input power, MRRs radii and coupling coefficients can change and plays important role in determining the results in which the continuous signals are generated spreading over the spectrum. Large bandwidth signals of optical soliton are generated by the input pulse propagating within the MRRs, which is allowed to form the continuous wavelength or frequency with large tunable channel capacity. The continuous variable QKD is formed by using the localized spatial soliton pulses via a quantum router and networks. The selected optical spatial pulse can be used to perform the secure communication network. Here the entangled photon generated by chaotic signals has been analyzed. The continuous entangled photon is generated by using the polarization control unit incorporating into the MRRs, required to provide the continuous variable QKD. Results obtained have shown that the application of such a system for the simultaneous continuous variable quantum cryptography can be used in the mobile telephone hand set and networks. In this study frequency band of 500 MHz and 2.0 GHz and wavelengths of 775 nm, 2,325 nm and 1.55 µm can be obtained for QKD use with input optical soliton and Gaussian beam respectively.","PeriodicalId":6354,"journal":{"name":"2010 International Conference on Enabling Science and Nanotechnology (ESciNano)","volume":"19 1","pages":"1-2"},"PeriodicalIF":0.0,"publicationDate":"2010-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83788507","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
