This proposal hypothesizes that differences in bone’s chemical and nano-structural composition can be directly related to bone strength. The specific aim is to use detailed chemical, mechanical, and nano-structural assays in situ to identify which specific physical, chemical, and structural properties determine the strength and quality of bone.


Which Comes First, the Eggshell or its Genes? Mimicking Biomineralization with Artificial Protein Networks

Miriam Rafailovich

Elaine DiMasi
National Synchrotron Light Source, BNL

Nadine Pernodet
Department of Materials Science and Engineering, SBU

This proposal endeavors to answer the questions, What are the functions of the associated biomacromolecules? and What stabilizes the non-equilibrium mineral phases? in specific ways for calcium carbonates, combining polymer science, tissue engineering and environmental AFM imaging with the cutting-edge synchrotron x-ray scattering methods developed at BNL to study mineralization in-situ.


Analysis of Radio Scattering Data to Study Ultra-High Energy Cosmic Ray Air Showers

Michael Rijssenbeek
Department of Physics and Astronomy, SBU

Denis Damazio
Physics Department, BNL

Tara Falcone
Department of Physics and Astronomy, SBU

Helio Takai
Physics Department, BNL

This proposal, intends to complete a detailed study of the echo signals collected by a receiver station, for the development of pattern recognition and data reduction, and for the analysis of the combined data from radio receivers and several distributed muon detectors.


Probing Potential Cellular Toxicity of Purified Carbon Nanotubes and Perovskite Nanotubes

Stanislaus Wong
Chemistry Department, SBU

Barbara Panessa-Warren
Department of Materials Science, BNL

The aim of this proposal is to examine the effect of functionalized carbon nanotubes/perovskite nanostructures on tissue culture cells and measure cell death, either necrosis or apoptosis, if cell death does not occur, the effect of nanomaterials on cellular function will be measured.
