  1. Nano-engineering of Lattice Dimensionality for Soft MatterLarry R. Dalton, University of Washington, DMR 0905686 ►Polymers and dendrimers are constructed using specific spatially-anisotropic intermolecular interactions that control lattice dimensionality. ►Reduced lattice dimensionality leads to enhanced acentric order for electrically-poled materials, which in turn leads to improved physical properties such as electro-optic activity. ►Choice of interactions to be utilized is guided by theoretical calculations, which also correctly predict electro-optic activity, dielectric permittivity, etc. ►New techniques for defining lattice dimensionality (M) have been developed and lattice dimensionality is related to order parameters <cos3q> and <P2> by Measurement of acentric and centric order parameters show that dendrimers constructed with coumarin (C1) or arene-perfluoroarene (HDFD) dendrons yield 2-D lattices while chromophore-polymer composites and traditional dendrimers yield 3-D lattices. The existence of 2-D phases is confirmed by shear modulation force microscopy (SM-FM) – regions indicated below

  2. Technology Transfer and Workforce DevelopmentLarry R. Dalton, University of Washington, DMR 0905686 Workforce Development ► Prof. Dalton serves on the advisory boards of Norfolk State University, Alabama A&M University and other minority serving institutions. This includes the NSU NSF PREM Center on metamaterials and continued assistance with development of the NSU Ph.D. program in MS&E. ► Prof. Dalton works with King and Kitsap area high schools on the implementation of on-site special science programs and on mentoring of students. Moreover, more than 30 high school and college undergraduate students (not counting NSF REU students) participate in research and educational experiences in the Dalton UW research labs each year. ►83% of the Dalton group members are from under-represented groups. Knolwedge & Technology Transfer ► Research featured in ACS (J. Phys. Chem., Chem. Rev., Acc. Chem. Res., Chem. Mater. Symp. Ser.), RSC (J. Mater. Chem.), IEEE, and SPIE publications. ► Lumera/Gigoptix devices pass Telcordia standards; achieve 200 Gbps operation. ► New hybrid organic NLO/silicon photonic devices developed. Optical and RF fields concentrated in 25 nm slot containing organic EO material ► Materials & Info. provided to Boeing, Intel, U. of Delaware, UCLA, AFRL, Norfolk State U. PREM, etc.
