1. Self-Assembled Bicontinuous Double Gyroid Solar CellUlrich B. Wiesner,Cornell University, DMR 0605856 For more than twenty-five years bicontinuous cubic network structures from block copolymer self-assembly, called double Gyroids, are known in polymer science. They have been the subject of numerous experimental and theoretical studies and captured the imagination of many researchers because of their beauty and their relation to mathematical (minimal) surfaces. Now, a collaboration of researchers from five different institutions in England (Cambridge & Oxford), Germany (Freiburg), and the US (Minnesota & Cornell) has demonstrated the first electronic device from a block copolymer Gyroid structure, a solid-state dye-sensitized solar cell (ssDSC) with state of the art performance.

2. Self-Assembled Bicontinuous Double Gyroid Solar CellUlrich B. Wiesner, Cornell University, DMR 0605856 Working with the excellent and proven platforms of the NSF funded Cornell Center for Materials Research (CCMR) and Nanobiotechnology Center (NBTC), the Wiesner group has built a multifaceted outreach program including education, outreach, broadening participation of underrepresented groups, industrial and international collaborations, and organization of workshops and symposia.
