Identification of a mechanogenetic link between substrate stiffness and chemotherapeutic response in breast cancer

February 25, 2019
Author(s)
Brian G. Bush, Scott H. Medina, Emily Sevcik, Maggie Cam, Frank W. DelRio, Kaustav Nandy, Joel P. Schneider
Mechanical feedback from the tumor microenvironment regulates an array of processes underlying cancer biology. For example, increased stiffness of mammary extracellular matrix (ECM) drives malignancy and alters the phenotypes of breast cancer cells

Two-Dimensional Strain-Mapping by Electron Backscatter Diffraction and Confocal Raman Spectroscopy

November 27, 2017
Author(s)
Andrew J. Gayle, Lawrence Henry Friedman, Ryan Beams, Brian G. Bush, Yvonne B. Gerbig, Chris A. Michaels, Mark D. Vaudin, Robert F. Cook
The strain field surrounding a spherical indentation in silicon is mapped in two dimensions (2- D) using electron backscatter diffraction (EBSD) cross-correlation and confocal Raman spectroscopy techniques. The 200 mN indentation created a 4 m diameter

Heterogeneity and length scale effects in PEG-based hydrogels

August 10, 2015
Author(s)
Brian G. Bush, Jenna M. Shapiro, Frank W. DelRio, Robert F. Cook, Michelle L. Oyen
Colloidal-probe spherical indentation load-relaxation experiments are conducted on poly(ethylene glycol) (PEG) hydrogel materials to quantify the steady-state mechanical properties and time-dependent transport properties in a single experiment. A probe

Low Temperature Plasma for Bevel Crater Depth Profiling of Crosslinking Organic Multilayers: Comparison with C60 and Argon Gas Cluster Sources

July 6, 2014
Author(s)
Shinichiro Muramoto, Derk Rading, Brian G. Bush, John G. Gillen, David G. Castner
A model delta layer system made of thin films of an organometallic chelate and an aromatic molecule (aluminum hydroxyquinolinate and bathocuproine), both that crosslink under traditional ion beam irradiation, was used to evaluate the effectiveness of using

Frictional properties of native and functionalized type I collagen thin films

October 2, 2013
Author(s)
Koo-hyun Chung, Antony Chen, Christopher Anderton, Kiran Bhadriraju, Anne L. Plant, Brian G. Bush, Robert F. Cook, Frank W. DelRio
Frictional properties of native and fibronectin (FN)-functionalized type I collagen (COL) thin films were studied via atomic force microscopy. The COL lateral contact stiffness was dependent only on the hydration state, indicating that shear deformation

Effect of Organic SAMs on the Evolution of Strength of Silicon Nanostructures

June 3, 2013
Author(s)
Scott Grutzik, Brian G. Bush, Frank W. DelRio, Richard S. Gates, Melissa Hines, Alan Zehnder
The ability to accurately predict the strength of nanoscale, single crystal structures is critical in micro- and nano-electromechanical systems (MEMS and NEMS) design. Because of the small length scales involved failure does not always follow the same

Interfacial Mechanical Properties of n-Alkylsilane Monolayers on Silicon Substrates

February 1, 2013
Author(s)
Brian G. Bush, Frank W. DelRio, Cherno Jaye, Daniel A. Fischer, Robert F. Cook
The interfacial properties of n-alkylsilane self-assembled monolayers on silicon were investigated by normal force spectroscopy and lateral force measurements and correlated with molecular structure via near-edge X-ray absorption fine structure (NEXAFS)

Characteristics of Graphene for Quantized Hall Effect Measurements

June 1, 2012
Author(s)
Randolph E. Elmquist, Mariano A. Real, Irene G. Calizo, Brian G. Bush, Tian T. Shen, Nikolai N. Klimov, David B. Newell, Angela R. Hight Walker, Randall M. Feenstra
This paper describes concepts and measurement techniques necessary for characterization of graphene in the development of graphene-based quantized Hall effect (QHE) devices and resistance standards. We briefly contrast the properties of graphene produced
