MATERIALS SCIENCE: A Unique Platform for Materials Design Timothy P. Lodge Science 4 July 2008: 50-51. By combining ionic liquids with block polymers, a virtually unlimited range of composite materials can be prepared. Self-Sorted, Aligned Nanotube Networks for Thin-Film Transistors Melburne C. LeMieux, Mark Roberts, Soumendra Barman, Yong Wan Jin, Jong Min Kim, and Zhenan Bao Science 4 July 2008: 101-104. Treating silicon substrates with a silane layer allows them to absorb spin-coated, semiconducting carbon nanotubes, yielding aligned and densely packed nanotube films. Characterization of Step-Edge Barriers in Organic Thin-Film Growth Gregor Hlawacek, Peter Puschnig, Paul Frank, Adolf Winkler, Claudia Ambrosch-Draxl, and Christian Teichert Science 4 July 2008: 108-111. In contrast to the growth of inorganic films, bending of a rod-shaped organic molecule at step edges and its anisotropy leads to a change from growth of layers to terraced mounds. Mg/Al Ordering in Layered Double Hydroxides Revealed by Multinuclear NMR Spectroscopy Paul J. Sideris, Ulla Gro Nielsen, Zhehong Gan, and Clare P. Grey Science 4 July 2008: 113-117. Rapid sample spinning during nuclear magnetic resonance spectroscopy reveals a highly ordered cation distribution in layered materials.
