Laser Carbon Interactions

Vander Wal R., Abrahamson J., Penn State University, US

This presentation describes laser heating of carbon materials. The carbon industry has been annealing carbon via traditional furnace heating since at least 1800, when Sir Humphry Davy produced an electric arc with carbon electrodes made [...]

Interfacial nanostructure dictates macro-structural properties of carbon-carbon composites

Singh M., Vander Wal R., Pennsylvania State University, US

Carbon-carbon composites, originally developed for aerospace applications, are materials that consist of a carbonaceous matrix with an embedded carbon filler providing the required reinforcement for thermal and mechanical stability. An important aspect of composites is [...]

Laser Annealing Nanoscale Carbons: Material Transformations

Vander Wal R., Abrahamson J., Gaddam C., Penn State University, US

Laser processing of materials is not new, but using lasers to anneal, bond and otherwise transform carbons is. Fundamental understanding of the dependence upon carbon structure, morphology and chemistry is critical to implementing this technology [...]

MonteCarlo Simulations of Carbon-based Structures Based on Extended Brenner Potential

Petukhov A.V., Fasolino A., Research Institute for Materials, Institute of Theoretical Physics, University of Nijmegen, NL

Extended grand-canonical off-lattice Monte Carlo simulations of the (100) and (111) diamond surfaces have shown that the Brenner potential is extremely accurate in describing the structural properties at surfaces, supporting the recent predictions of new [...]
