Self-Assembled Monolayers: Effect of Chain Length on Nanofriction

September 6, 2006
Author(s)
S Hsieh, S Sambasivan, J V. Sengers, Stephen M. Hsu
We measured the interfacial friction of a series of alkylsilanes with chain lengths from C5 to C30 on silicon (100) surfaces using an Atomic Force Microscope (AFM). The dependence of the friction on chain length exhibits an optimum curvature with C12

Raman Spectroscopic Monitoring of Droplet Polymerization in a Microfluidic Device

September 1, 2006
Author(s)
Susan E. Barnes, Zuzanna T. Cygan, Kathryn Beers, Eric J. Amis, Jesse K. Yates
Thiolene based microfluidic devices were used to generate droplets of benzyl methacrylate monomer and hexanediol dimethacrylate crosslinker mixtures suspended in a water/surfactant continuous phase. A gradient of droplet composition was established and the

Encapsulated Chondrocyte Response to Pulsatile Flow Bioreactor

August 16, 2006
Author(s)
James A. Cooper, W Li, L A. Bailey, Steven D. Hudson, Sheng Lin-Gibson, Kristi S. Anseth, Rocky Tuan, N Washburn
We have developed a bioreactor using microfluidic techniques that allow for dynamic culture conditions and measurement of the fluid flow impinging upon a three-dimensional (3-D) tissue engineering (TE) scaffold. Chondrocytes in scaffolds have been shown to

Anti-Biofouling Properties of Comb-Like Block Copolymer With Amphiphilic Side-Chains

August 11, 2006
Author(s)
Sitaraman Krishnan, R Ayothi, A Hexemer, J Finlay, K E. Sohn, R Perry, Christopher K. Ober, E J. Kramer, M E. Callow, J A. Callow, Daniel A. Fischer
Surfaces of novel block copolymers with amphiphilic side chains were studied for adhesion of marine organisms. the surface-active polymer, obtained by grafting fluorinated molecules with hydrophobic and hydrophilic blocks to a block copolymer precursor
