Ion induced bending is a promising controlled technique for manipulating nanoscale structures. However, the underlying mechanism of the process is not well understood. In this letter, we report a detailed study of the bending mechanism of Si nanowires (NWs) under Ga+ irradiation.
Elevated temperature sliding contact experiments were carried out on an Al-Mg alloy AA5083 to study the formation of oxide fibres on their surface. Deformation and friction tests were conducted at a constant strain rate of 4×10−2 s−1 at temperatures 350 °C, 450 °C and 545 °C.

Engineering domains in ferroelectric thin films is crucial for realizing technological applications including non-volatile data storage and solar energy harvesting. Size and shape of domains strongly depend on the electrical and mechanical boundary conditions.
This work was performed in collaboration with Dr. Phil Rice and Dr. Teya Topuria of IBM Almaden Research Center in San Jose, CA who provided expert assistance as well as the TEM specimen and access to their microscope facilities.
Colorized EELS elemental map of Ti L2,3-edges at 456 eV (green), Mn L2,3-edges at 640 eV (blue), La M4,5-edges at 832 eV (purple) and Sr L2,3-edges at 1940 eV (red).

Ultrafine TaOx nanoparticles were electrodeposited on carbon black (CB) powder in a nonaqueous Ta complex solution at room temperature, and the resultant TaOx/CB catalysts were assessed as oxygen reduction reaction (ORR) electrocatalysts for polymer electrolyte fuel cell (PEFC) cathodes.
