Graphene nanoplatelets
exfoliation
Given
the current status of graphene, a unique 2D material,
and its applications,
exploring methods of graphene mass-production is of
paramount importance.
Direct exfoliation of graphene from graphite, without
the unwanted effects
of oxidation and/or intercalation, provides large amounts of defect-free
graphene nanoplatelets.
Suitable surfactant choice is crucial for this purpose.

- Coherent and noncoherent
transport in quasi-one-dimensional systems
(nanotubes, nanowires, ...)
As shrinking size of electronic
components causes them to have nanometer length scales,
transport properties (both electronic and thermal) are governed by the quantum
mechanics.
This results in new opportunities and challenges in
designing nano and molecular
electronic devices. Of special interest are the
finite temperature effects and
electron-phonon interactions.

- Electronic structure and molecular dynamics of hydrogen-containing nanocages
Hydrogen-containing nanocages
provide novel solutions to the hydrogen storage
problem, which is essential in using hydrogen as a renewable and clean source
of
energy. Simulating the properties of such systems requires accurate electronic
structure
and molecular dynamics methods.

- Phase transition and electrorheology in nanotube suspensions
Nanostructured fluids possess novel
characteristics and immense potentials.
Controlling phase transition in nanostructured fluids is a key to their
application.
Phase transition in nanotube suspensions, e.g., can be controlled by applying
electric field. A wide range of applications can be considered, for example
superior dampers, heat and charge transfer , as well as cancer therapy.

- Nanosensors
When the unique electronic and transport properties
of nanoscale systems are combined
with their affinity for various molecules, nanosensor
functionality will be the natural
result. Changes in electronic transport properties of nanotubes as a result of
gas molecules
adsorption, e.g., are shown to provide superior sensor potentials.

- Nanoelectromechanical systems
Mechanical properties of nanometer scale systems
exhibit unique features which can
be exploited for novel applications. Seamless and reversible bending of systems
such as
nanotubes can be used together with their transport properties in order to
design
nanoelectromechanical sensors and switches.

- Nanostructured composites
Incorporating nanoparticles, nanotubes, nanoribbons, etc. within material matrices
can enhance their mechanical, transport and optical properties significantly.
Same kinds
of significant changes occur in nanoscale systems
when they are doped with individual
atoms and ions or with atomic clusters. Novel nanosheets
can have unique electronic
and mechanical properties.

- Activated processes
Some of the most important processes which
occur in nature or in labs are activated;
i.e., they do not proceed without an activating force, as the reactants and
products
are separated by an energy barrier. Simulating such physical and chemical
processes
requires especial considerations, to effectively map their minute/hour time
scales to
the femtosecond/picosecond domain of accurate molecular dynamics studies.
