Chiral, multipetal gold nanoflowers (AuNFs) with crystalline tips were synthesized in high yield through the reduction of HAuCl4 in water in presence of preformed core-satellite Ag nanoparticle (AgNPs) seeds.
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.
