One dimensional (1D) silicon nanostructures have attracted significant interest as an anode material for lithium ion batteries (LIBs) as its 1D geometry accommodates the large volume change of the Si during cycling and enables facile electron transport during all stages of operation. Furthermore, the high aspect ratio of 1D Si nanostructures enables us to investigate atomic-scale mechanisms of the lithiation process and corresponding volume change behavior. Various 1D nanostructures with different morphologies and compositions have been explored to achieve a robust cycle performance, reversible morphological changes, and high rate capabilities. In this Perspective, we summarize the recent significant advances of 1D Si nanostructures and discuss electrode design strategies based on the recent geometry and composition engineering.

Science, it's hard for RWers

When Felix Fischer of the U.S. Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) set out to develop nanostructures made of graphene using a new, controlled approach to chemical reactions, the first result was a surprise: spectacular images of individual carbon atoms and the bonds between them.
"We weren't thinking about making beautiful images; the reactions themselves were the goal," says Fischer, a staff scientist in Berkeley Lab's Materials Sciences Division (MSD) and a professor of chemistry at the University of California, Berkeley

Nanotubes Increase Solar PV Conductivity 100 Million-Fold  — Sourceable
Carbon-based nanostructures are already being used as materials in solar cells with increasing frequency, yet their ability to enhance electrical performance has thus far been hampered by limited ability to assemble orderly networks using the materials.
