New paper published in Frontiers in Energy Research - It's on our new work on probing the mechanical stresses in silicon nanowires as anodes in lithium-ion batteries. Congratulations, Sasi and Ihor! Probing Stress States in Silicon Nanowires During Electrochemical Lithiation Using In Situ Synchrotron X-Ray Microdiffraction Imran Ali1, Sasi Kumar Tippabhotla1, Ihor Radchenko1, Ahmed Al-Obeidi2, Camelia V.

However, silicon expands up to 300% during lithiation, which induces high stresses and leads to fractures. To design silicon nanostructures that could minimize fracture, it is important to understand and characterize stress states in the silicon nanostructures during lithiation. Synchrotron X-ray microdiffraction has proven to be effective in revealing insights of mechanical stress and other mechanics considerations in small-scale crystalline structures used in many important technological applications, such as microelectronics, nanotechnology, and energy systems. In the present study, an in situ synchrotron X-ray microdiffraction experiment was conducted to elucidate the mechanical stress states during the first electrochemical Read More

Prof Arief Budiman interviewed by CNA news -   Prof Arief Budiman was interviewed by Channel Newsasia (CNA) to share his insights on the Housing and Development Board (HDB) approach to renewable solar energy by the announcement of solar leasing tenders to install many solar panels across Singapore. Check it out! HDB calls 'largest tender' to install solar panels across government agencies Channel NewsAsia, 1 Nov 2017 http://www.channelnewsasia.com/news/singapore/hdb-calls-largest-tender-to-install-solar-panels-across-9365000 SINGAPORE: The Housing and Development Board (HDB) has called what it says is its largest solar leasing tender to date, it announced in a joint release with the Singapore Economic Development Board (EDB) on Wednesday (Nov 1).   This is the third tender to be launched under the SolarNova programme which is jointly led by HDB and the EDB. The first SolarNova tender was awarded in December 2015 and the second was awarded in June this year.   This third tender will aggregate demand for the installation of solar panels across eight governmental agencies, including the Building and Construction Authority, Institute of Technical Education, National Heritage Board and Sport Singapore.   Compared to previous tenders, more HDB blocks have been identified for this tender, said the joint release.   A total of 848 HDB blocks under West Coast and Choa Chu Read More
EPD Lecture Series Talk by Prof Francesca Iacopi - Prof Francesca Iacopi and Prof Budiman went back several years when their career paths kept overlapping each other – first in Silicon Valley, Bay Area (where they worked together for AMD/GlobalFoundries) and now here in Asia Pacific! It is our pleasure to welcome Prof. Iacopi at SUTD and present in this distinguished EPD Lecture Series.
Singapore 3MT Finalist – Sasi performance @ NTU - Sasi Kumar Tippabhotla was one of the finalists representing SUTD for the Three Minute Thesis (3MT) competition organised by Springer Nature Asia. It was a great showdown between the four universities @ NTU on 4 Aug 2017 evening. Well done for making this far! Check out the highlights To be able to say your four year PhD research in 3 minutes is no easy feat. For the twenty contestants who were at NTU on Friday, they did well in explaining their research and interest their crowd with their speeches. Sasi talked about how he could improve the solar cell performance through the reduction of cell stress and quantify it through high energy x-rays (or synchrotron x-ray diffraction). Well done for making XML group proud by presenting your work to Singapore!

Prof Budiman’s talk in Scientific highlights of MRS Spring meeting 2017 - Prof Budiman presented the work of Biomimetic, Strong yet Tough Composites through 3D Printing by Yinning Zhou, Komal Agarwal  in NM6: Mechanical Behavior of Nanostructured Composites symposium on Tuesday 18 Mar 2017. It received as one of scientific highlights in the MRS Spring Meeting 2017! The talk got very good responses and attracts quite a bit of interests. The MRS community is now looking forward to hearing further exciting findings from us! I think they are excited especially with smaller scale fibers. On with our march to biomimetic, additively manufactured materials design science!
