Characterization of Mechanical Deformation of Nanoscale Volumes 2003 6 pages
Authors:  Christopher R. Perrey; William M. Mook; C. B. Carter; William W. Gerberich; MINNESOTA UNIV MINNEAPOLIS DEPT OF CHEMICAL ENGINEERING AND MATERIALS SCIENCE
The full text of this report is available for sale.The mechanical properties of nanoscale volumes and their associated defect structure are key to many future applications in nanoengineered products. In this study techniques of mechanical testing and microscopy have been applied to better understand the mechanical behavior of nanoscale volumes. Nanoindentation has been used to investigate important mechanical material parameters such as the elastic modulus and hardness for single nanoparticles. New sample preparation methods must be developed to allow ...


Characterization of Nanoparticle Films and Structures Produced by Hypersonic Plasma Particle Deposition 2003 7 pages
Authors:  Christopher R. Perrey; Ryan Thompson; C. B. Carter; Ashok Gidwani; MINNESOTA UNIV MINNEAPOLIS DEPT OF CHEMICAL ENGINEERING AND MATERIALS SCIENCE
The full text of this report is available for sale.There is great potential for the use of nanostructures in numerous applications. Investigation of nanoparticle films and structures is an important area of research for the production of nanoengineered devices. However for these devices to become a reality, a production method that can yield high-rate synthesis of nanostructured powders is necessary. The hypersonic plasma particle deposition (HPPD) process has been shown to be capable of such high-rate production of nanoparticle ...
