Investigation of Patterned Media Concept for Very High Magnetic Storage Density

Horton B., Streator J.L., Georgia Institute of Technology, US

One potential architecture for very high magnetic storage density, called perpendicular recording, orients the magnetic domains normal to the media surface to achieve a higher domain volume and therefore increase the thermal stability. Additionally patterned [...]

Supramolecular Self-assembly of Carbon Structures from Shungite Rock Using Only Water

Osipov E., Osipov S., Reznikov V., Osipov E., Osipov S., Shestakov Yu., Satakunta Polytechnic, Technology, Pori, Finland, FI

In spite the fact that fullerene and any type of carbon are not soluble in water the main goal of this work is to produce evidence of realization of a supramolecular self-assembly of carbon structures [...]

Self-Assembly of TPPS4 Porphyrin Molecules into Nanorods Investigated by TEM, AFM, STM and UV/VIS Spectroscopy

Snitka V., Rodaite R., Mizariene V., Kaunas University of Technology, LT

In this work the aggregates of the tetrakis(4-sulfonatophenyl)porphyrin (TPPS4) growth from solution on solid crystalline hydrophilic and hydrophobic substrates were investigated. The spatial structure of TPPS4 deposited on the surface was imaged using Transmission Electron [...]

Hydrodynamically Driven Self-Assembly of Block Copolymers Studied by On-Line Small Angle X-Ray Scattering

Panine P., European Synchrotron Radiation Facility E.S.R.F., FR

A new technique of controlling the supramolecular structure of block copolymer solutions is presented. It consists in monitoring by small angle x-ray scattering the large-scale structure of soft condensed matter and simultaneously recording its rheological [...]

Control Synthesis of Functional Nanoassemblies using Langmuir-Blodgett Method

Wang H.-L., Tang Z., Gao Y., Magyar R.J., Tretiak S., Shreve A.P., Los Alamos National Laboratory, US

We strive to design syntheses of a series of amphiphilic molecular building blocks that can self-assembled at the air-water interface to form 2D and 3D nanostructures with specific opto-electronic properties. Compression of these molecular building [...]

Micropatterned Laminin-1 Matrices

Sgarbi N., Pisignano D., Di Benedetto F., Aloisi A., Nicolardi G., Cingolani R., Rinaldi R., Leece University, IT

We have obtained self-assembled laminin-1 networks on glass, realized by one-step microcontact printing lithography, without any preliminary functionalization of the substrates. We investigated the realized patterns by indirect immunofluorescence and atomic force microscopy (AFM), in [...]

Hierarchical Natural Materials: Nanostructured Keratin

Martínez-Hernández A.L., Velasco-Santos C., de Icaza M., Martínez-Hernández A.L., Santiago-Valtierra A.L., Castaño V.M., CFATA-UNAM /ITQ, MX

Smart materials are required in devices in order to develop different functions referent to control and automation. The performance and applications of these materials have been growing in the last years and recently their development [...]

Peptide Based Nanoparticles as a Platform for Vaccine Design

Raman S.K., Kao D.J., Tropel D., Graff A., Machaidze G., Hodges R.S., Burkhard P., Biozentrum, CH

To-date vaccines for many of the dreadful diseases such as Tuberculosis, Malaria, AIDS and Hepatitis are still ineffective or unavailable. Peptide based vaccines have been developed but because of their poor immunogenic response and the [...]

Characterization of a Novel Self-Association of an Alternating Copolymer into Nanotubes in Solution

Malardier-Jugroot C., van de Ven T.G.M., Whitehead M.A., McGill University, CA

The characterisation of the association of an alternating copolymer was performed using theoretical methods (quantum mechanics and molecular mechanics) and experimental methods (cryo-Transmission Electron Microscopy, Neutron Reflectivity and Neutron Scattering). The most stable conformation obtained [...]
