Multiscale Characterization of Biological Systems : Spectroscopy and Modeling

This book covers the latest research work done in the area of interface mechanics of collagen and chitin-based biomaterials along with various techniques that can be used to understand mechanics of biological systems and materials. Topics covered include Raman spectroscopy of biological systems, scale dependence of the mechanical properties and microstructure of crustaceans thin films as biomimetic materials, as well as the role of molecular-level modeling. The use of nanomechanics to investigate interface thermomechanics of collagen and chitin-based biomaterials is also covered in detail.

This book also:

• Details spectroscope experiments as well as nanomechanic experiments

• Reviews exhaustively phenomenological models and Raman spectroscopy of biological systems

• Covers the latest in multiscaling for molecular models to predict lab-scale sample properties and               investigates interface thermomechanics

Vikas Tomar is an Associate Professor at Purdue University-West Lafayette. His research focuses on understanding how interfaces contribute to failure of complex materials with a specific emphasis on microstructural issues. He has developed three different multiscale modeling methods and a new experimental scheme called nanomechanical Raman spectroscopy. Dr. Tomar has been a recipient of multiple research awards, including the inaugural Material Science and Engineering-C Young Researcher award. He is Editor-in-Chief of the International Journal of Experimental and Computation Biomechanics and is an Associate Editor of the Journal of Engineering Materials and Technology. He is an associate fellow of AIAA.

Devendra Dubey is an Assistant Professor in Mechanical Engineering Department at the Indian Institute of Technology Delhi, India. He received his Ph.D. from Purdue University, Indiana, USA; MS in mechanical engineering from University of Notre Dame, Indiana, USA; and Bachelor’s degree from Indian Institute of Technology Bombay, Mumbai, India. Dr. Dubey works in the general area of computational mechanics at multiple length scales with a focus on understanding interfacial interactions and structure-property. He has previously worked on nanomechanics of polymer-ceramic type collagen-hydroxyapatite biomaterials and his current research involves nanomechanics of brittle of bone disease, impact mitigation of ballistic structures, biomechanics and bio-tribology of knee and hip joints, mechanical reliability of solar cells, and blast injury mechanics of human body.
