Femtosecond Transient Absorption Measurements system Hatteras.
Future nanostructures and biological nanosystems will take advantage not only of the small dimensions of the objects but of the specific way of interaction between nano-objects. The interactions of building blocks within these nanosystems will be studied and optimized on the femtosecond time scale - says Sergey Egorov, President and CEO of Del Mar Photonics, Inc. Whether you want to create a new photovoltaic system that will efficiently convert photon energy in charge separation, or build a molecular complex that will dump photon energy into local heat to kill cancer cells, or create a new fluorescent probe for FRET microscopy, understanding of internal dynamics on femtosecond time scale is utterly important and requires new advanced measurement techniques such as our Femtosecond Transient Absorption Measurements system Hatteras

Excited state processes in electronic and bio nanomaterials (ESP2007)

Los Alamos National Laboratory October 1-4, 2007

During the past 15 years, extraordinary experimental advances have made the manipulation and fabrication of structures at the nanoscale possible. Parallel developments of theoretical and simulation capabilities aim to achieve quantitative understanding and prediction of fundamental physical properties of these materials. This interdisciplinary workshop will provide an open forum for active interactions between researchers from different subfields.

The scope of the conference is a variety of excited state phenomena in technologically important materials and biosystems, including size-dependent and time-dependent electronic interactions, excited state dynamics, quantum confinement, and carrier transport, emphasizing similarity of the phenomena rather than specifics of the systems.

Topical areas:

· Organic polymers and nanotubes: ultrafast processes and functional devices;
· Organo-metallic complexes: excited state potentials and photocatalysis;
· Semiconductor nanocrystals: from novel structures to novel physical phenomena;
· Biosystems: conformations, energy/charge transport, spectroscopy and photosynthesis.
