Nanoforum - Nanotech Regulatory Document Archive

On the base of the above mentioned possibilities the group of the Cryoelectronic
Department can participate on the research programs oriented on the preparation
and characterisation of structures in micrometers and sub-micrometers dimensions.
The main interest of the group is structures for detectors (single photon detector),
nanometrology (current standard) and cryoelectronic devices based on the high Tc
(YBa2Cu3O7-x) and medium Tc (MgB2) superconductors.

Research subject for a potential FP6 project :
The volume of materials based on polymers is steadily increasing. The traditional
way of preparation of new polymeric materials through new or conventional
monomers is still open but seems to be rather limited. The open and promising way for
preparation of new polymeric materials such as functionalised nano-structure polymer
materials, fine and coarse polymer dispersions, percolationlike (conductive) polymer
matrices etc. is to polymerise common or new monomers in a nonconventional way
to produce nano-particles with controlled size and distribution in any type of
heterogeneous polymerisation. The nanoparticles besides using them as fillers or
micro-reactors can carry various functions e.g. catalytic, conductive, thermoresponsive,
pH-responsive, etc.
These materials are of great interest because of their surface-active properties and
therefore they can serve as the stabilisers of dispersions or compatibilizers of
polymers and carrier of drugs and sensors of different types. New properties are
expected from polymeric materials based on both conventional and new monomers and
polymers and the blends of synthetic and natural polymers.
These materials will have a complex structure with a unique morphology and phase
behaviour. The morphology will be dominated by domains is in the nano-region. The
development of new processes will be needed to prepare these micro-domains in situ of
the conventional polymers.
These new materials will have unique optical, mechanical, electrical properties. The
morphology and properties will vary with the size of domains and the interface area
between the continuous and dispersed phases within the integral complex approach to
advanced polymer materials development computer modelling based on molecular
simulations (Monte Carlo method) will be included. This will help to elucidate the
behaviour of macromolecules on micro- and nano-scale and provides one of few
routes for the transition from trial and error approach in macromolecular applications to a
knowledge-based approach.
