Recent Publication(s)

  • "Modulation of Wnt/β-catenin signaling in human embryonic stem cells using a 3-D microwell array"

Azarin SM, Lian X, Larson EA, et al., Biomaterials 33(7):2041-9 Mar 2012. Here we have used a microwell culture system that produces 3-D colonies of uniform size and shape to provide insight into the effect of modulating cell-cell contact on canonical Wnt/β-catenin signaling in hESCs. PubMed/NLM

  • "Three-dimensional Directed Assembly of Block Copolymers together with Two-dimensional Square and Rectangular Nanolithography"

Ji SX, Nagpal U, Liao W, Advanced Materials 23(32): 3692 Aug 2011. Self-assembling sphere-forming block copolymers that normally adopt a hexagonal packing in thin films are directed to assemble on chemically patterned surfaces into their three-dimensional bulk-like body-centered cubic morphology.

  • "Pattern Dimensions and Feature Shapes of Ternary Blends of Block Copolymer and Low Molecular Weight Homopolymers Directed To Assemble on Chemically Nanopatterned Surfaces"

Nagpal U, Kang HM, Craig GSW, ACS Nano 5(7): 5673-5682 Jul 2011. Ternary blends of cylinder-forming polystyrene-block-poly(methyl methacrylate) (PS-b-PMMA) and low molecular weight PS and PMMA were directed to assemble on chemically patterned surfaces with hexagonal symmetry.

  • "Fivefold symmetry as an inhibitor to hard-sphere crystallization"

Karayiannis NC, Malshe R, de Pablo JJ et al., Physical Review E 83 (6): Jun 2011. Through molecular simulations we investigate the dynamics of crystallization of hard spheres of uniform size from dense amorphous states and the role that hidden structures in an otherwise disordered medium might have on it.
