111. Size Measurement of Nanoparticles using Atomic Force Microscopy
Topic: Nanomaterials
Published: 1/1/2011
Authors: Jaroslaw Grobelny, Frank W DelRio, Pradeep Narayanan Namboodiri, Doo-In Kim, Vincent A Hackley, Robert Francis Cook
Abstract: This chapter outlines procedures for sample preparation and the determination of nanoparticle size using atomic force microscopy (AFM). To start, procedures for dispersing gold nanoparticles on various surfaces such that they are suitable for imagin ...

112. Size Measurement of Nanoparticles using Atomic Force Microscopy
Topic: Nanomaterials
Published: 10/1/2009
Authors: Jaroslaw Grobelny, Frank W DelRio, Pradeep Narayanan Namboodiri, Doo-In Kim, Vincent A Hackley, Robert Francis Cook
Abstract: In this assay protocol, procedures for dispersing gold nanoparticles on various surfaces such that they are suitable for imaging and height measurement via intermittent contact mode AFM are first described. The procedures for AFM calibration and ope ...

113. Stable Single-Crystalline Body Centered Cubic Fe Nanoparticles
Topic: Nanomaterials
Published: 4/20/2011
Authors: Natalie F. Huls, Lise-Marie Lacroix, Don Ho, Xiaolian Sun, Shouheng Sun
Abstract: Air stable magnetic nanoparticles (MNPs) with high magnetization are required in order to fully realize optimized biomedical agents. However, only metallic NPs with good crystallinity such as Fe or FeCo, exhibit magnetization as high as 220 A.m.kg. T ...

114. Structure and Magnetic Properties of Electrodeposition Co on n-GaAs (001)
Topic: Nanomaterials
Published: 9/19/2003
Authors: A X Ford, John E Bonevich, Robert D McMichael, Mark D Vaudin, Thomas P Moffat
Abstract: Co thin films have been electrodeposited on n-type (001) GaAs. The structure and texture of the films were investigated using x-ray diffraction (XRD) and transmission electron microscopy (TEM) while the magnetic properties were examined using a vibr ...

115. Substrate Hybridization and Rippling of Graphene Evidenced by Near-Edge X-ray Absorption Fine Structure Spectroscopy
Topic: Nanomaterials
Published: 5/1/2010
Authors: Daniel A Fischer, V. J. Lee, Patrick S Lysaght, Sarbajit Banerjee
Abstract: Interfacial interactions at graphene/metal and graphene/dielectric interfaces are likely to profoundly influence the electronic structure of graphene. We present here the first angle-resolved near-edge X-ray absorption fine structure (NEXAFS) spectro ...

116. Surface Energy/Chemistry Gradients for Block Copolymer Thin Film Studies
Topic: Nanomaterials
Published: 8/2/2010
Authors: Julie N. L. Albert, Michael J. Baney, Christopher M Stafford, Jennifer Y. Kelly, Thomas H Epps
Abstract: Development of self-assembling block copolymer materials for emerging nanotechnologies requires an understanding of how surface energy and chemistry affect thin film phase behavior. Gradient methods provide an effective route to explore the role of ...

117. The Growth Kinetics of Nanocrystalline ZnO Colloidal Solutions
Topic: Nanomaterials
Published: 9/11/1998
Authors: E M Wong, John E Bonevich, P C Searson
Abstract: Colloidal chemistry techniques were used to synthesize ZnO particles in the nanometer size regime. Although the synthesis and unique properties of these materials are well known, the kinetics of the growth process are not well understood. The parti ...

Topic: Nanomaterials
Published: 1/1/2007
Author: Vinod K Tewary
Abstract: Line shapes of one phonon lines are calculated in the nuclear resonant inelastic X-ray scattering (NRIXS) from 57Fe embedded in a single-walled carbon nanotube using a computationally efficient phonon Green's function method which is also applicable ...

120. Thermal Cycling of Buried Damascene Copper Interconnect Lines by Joule Heating
Topic: Nanomaterials
Published: 1/1/2008
Authors: David Thomas Read, Roy Howard Geiss
Abstract: We report tests to failure of 300 nm wide damascene copper interconnect lines in silicon oxide dielectric, under high amplitude, low frequency alternating current. The cyclic minimum and maximum resistances were obtained from the measured voltage and ...
