NIST Reference Material Scaffolds Characterized for Cell Response

April 24, 2011
Author(s)
Carl G. Simon Jr., Jeff M. Coles
Reference scaffolds characterized for cell response are being developed for use as a standard for biological characterization of new scaffolds. The need for reference scaffolds to serve as a calibration standard between labs has been identified as critical

Optical illumination optimization for patterned defect inspection

April 20, 2011
Author(s)
Bryan M. Barnes, Richard Quintanilha, Martin Y. Sohn, Hui Zhou, Richard M. Silver
Rapidly decreasing critical dimensions (CD) for semiconductor devices drive the study of improved methods for the detection of defects within patterned areas. As reduced CDs are being achieved through directional patterning, additional constraints and

Stable Single-Crystalline Body Centered Cubic Fe Nanoparticles

April 20, 2011
Author(s)
Natalie F. Huls, Lise-Marie Lacroix, Don Ho, Xiaolian Sun, Shouheng Sun
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. Their

Strain-Based Temperature Memory Effect for Nafion(R) and Its Molecular Origins

April 20, 2011
Author(s)
Kirt A. Page, Scott Eastman, Tao Xie
A shape memory polymer traditionally refers to a polymer that can memorize one temporary shape and recover to its permanent shape upon exposure to an external stimulus. Although this basic concept has been known for at least half a century, recent advances

A new interface defect spectroscopy method

April 13, 2011
Author(s)
Jason T. Ryan, Liangchun (. Yu, Jae Han, Joseph J. Kopanski, Kin P. Cheung, Jason P. Campbell, Fei Zhang, Chen Wang, John S. Suehle, Vinny Tilak, Jody Fronheiser

A New Interface Defect Spectroscopy Method

April 12, 2011
Author(s)
Jason T. Ryan, Liangchun (. Yu, Jae Han, Joseph J. Kopanski, Kin P. Cheung, Fei Zhang, C Wang, Jason P. Campbell, John S. Suehle, Vinayak Tilak, Jody Fronheiser
A new interface defect spectroscopy method based on variable height charge pumping capable of observing the amphoteric nature of Si/SiO2 interface states in production quality sub-micron devices is demonstrated. It can help to resolve the long standing

Interfacial effects on droplet dynamics in Poiseuille flow

April 12, 2011
Author(s)
Jonathan T. Schwalbe, Frederick R. Phelan Jr., Petia Vlahovska, Steven D. Hudson
Interfacial rheology governs many properties of emulsions, and here we report theory that accounts for and measure surface viscous and elastic forces. Stokes flow is assumed in bulk phases and a jump in hydrodynamic stress at the interface is balanced by

Modulus-Driven Differentiation of Marrow Stromal Cells in 3D Is Independent of Cytoskeletal Integrity

April 11, 2011
Author(s)
Carl G. Simon Jr., Kaushik Chatterjee, Sapun Parekh, Sheng Lin-Gibson, Nicole M. Moore, Marcus T. Cicerone, Marian F. Young
Cell functions such as proliferation, migration, and differentiation are key physiological processes that are influenced by the physiochemical extracellular environment. We report on the effect of three-dimensional (3D) scaffold modulus on human bone

Separation of Empty and Water-Filled Single-Wall Carbon Nanotubes

April 11, 2011
Author(s)
Jeffrey A. Fagan, Jeffrey R. Simpson, JiYeon Huh, Jeffrey Blackburn, Larsen A. Brian, Josh M. Holt, Angela R. Hight Walker
The separation of empty and water-filled laser ablation and electric arc synthesized nanotubes is reported. Centrifugation of these large-diameter nanotubes dispersed with sodium deoxycholate using specific conditions produces isolated bands of empty and
