In a previous paper , we have demonstrated that a microcrystalline copper film well bonded to a polymer substrate can be stretched beyond 50% without cracking. The film eventually fails through the co-evolution of necking and debonding from the substrate. Here we report much lower strains to failure (around 10%) for polymer-supported nanocrystalline metal films, whose microstructure is revealed to be unstable under mechanical loading.

SERC launched the A*STAR Investigatorships last year. This prestigious award for top young research talent, tenable at their research institutes, aims to nurture young talent and build R&D capabilities in Singapore.

This year, the award is open for applications in the following areas:

The Singapore International Graduate Award (SINGA) is a collaboration between the Agency for Science, Technology & REsearch (A*STAR), the National Unviersity of Singaproe (NUS) and the Nanyang Technological University (NTU). PhD training will be carried out in English at your chosen lab at A*STAR Research Institutes, NUS or NTU. Students will be supervised by distinguished and world-renowned researchers in these labs. Upon successful completion, students will be conferred a PhD degree by either NUS or NTU.

Applications
