  1. Single Step Formation of Hierarchical Copper Oxide Nanostructures for Phase Change Applications Daniel C. Ralph, Cornell University, ECCS 0335765 A novel copper oxide nanostructure has recently been discovered that forms during a CVD silane deposition step of the process. The structure is unique in that is has a dual scale roughness (micro and nanoscale) and hence forms a hierarchical structured surface in one single step of CVD processing. Such surfaces could potentially be used for high-efficiency heat transfer applications such as enhancement of critical heat flux in boiling.
