221. Using Block Copolymer Self-Assembly to Imprint the Crystallization of Polymer Dendrites
Published: 8/10/2011
Authors: Sangcheol Kim, Alamgir Karim, Jack F Douglas, Christopher L Soles, R M Briber
Abstract: We utilize the self-assembly of cylinder-forming block copolymer (BCP) films to create templates for dendritic polymer crystallization patterns. This templating was achieved by simply spin-casting thin films from a solution containing both the BC ...

222. Using Pattern Homogenization of Binary Masks to Fabricate Microfluidic Structures With 3D Topography
Published: 5/2/2007
Authors: Francisco Javier Atencia, Susan E. Barnes, Jack F Douglas, John Meacham, Laurie E Locascio
Abstract: Because fluids at the microscale form three dimensional interfaces and are subject to three dimensional forces, the ability to create microstructures with modulated topography over large areas could greatly improve control over microfluidic phenomena ...

223. Water Immersion of Model Photoresists: Interfacial Influences on Water Concentration and Surface Morphology
Published: 2/1/2005
Authors: B D. Vogt, D L Goldfarb, M Angelopoulos, Christopher L Soles, C M Wang, Vivek M Prabhu, P M McGuiggan, Jack F Douglas, Eric K Lin, Wen-Li Wu, Sushil K. Satija
Abstract: Immersion lithography has emerged as an alternative to the 157 nm node and as such understanding of the interactions between the photoresist and immersion fluid (water) has become a pressing issue. The water concentration within the model photoresis ...

224. Wetting-Dewetting Transition Line in Thin Polystyrene Films
Published: Date unknown
Authors: K M. Ashley, D T Raghavan, Jack F Douglas, Alamgir Karim
Abstract: Thin polymeric films are increasingly being utilized in diverse technological applications and it is crucial to have a reliable method to characterize the stability of these films against dewetting. The parameter space that influences the dewetting ...

225. Wetting-Dewetting Transition Line in Thin Polystyrene Films
Published: 9/9/2005
Authors: H Raghavan, K M. Ashley, A Seghal, Jack F Douglas, Alamgir Karim
Abstract: We review recent advances in the application of combinatorial methods to polymer thin film characterization. Combinatorial methods allow the rapid exploration of multidimensional parameter spaces that naturally arise in the description of polymer f ...

226. What Do We Learn From the Local Geometry of Glass-Forming Liquids?
Published: 9/1/2002
Authors: Francis W. ~undefined~undefined~undefined~undefined~undefined Starr, Srikanth Sastry, Jack F Douglas, S C Glotzer
Abstract: We examine the local geometry of a simulated glass-forming polymer melt. Using the Voronoi construction, we find that the distributions of Voronoi volume $P(v_V)$ and asphericity $P(a)$ appear to be universal properties of dense liquids, supporting ...

227. Wrinkling and Strain Softening in Single-Wall Carbon Nanotube Membranes
Published: 3/26/2010
Authors: Erik K. Hobbie, Daneesh Olivia Simien, Jeffrey A Fagan, JiYeon Huh, Jun Y. Chung, Steven D Hudson, Jan Obrzut, Jack F Douglas, Christopher M Stafford
Abstract: Ultrathin layers of single-wall carbon nanotubes (SWCNTs) show considerable promise for applications ranging from fuel-cell membranes and biochemical sensors to bioactive films and transparent electrodes. The high conductivity and extreme anisotropy ...
