Guest lecture was held by advanced materials group inviting Dr. Dita Puspita Sari from Shibaura Institute of Technology, Japan on Monday, 26th of March 2018. The title of the lecture was “Chasing a dream on organic superconductors by muon spin rotation.”
Dr. Dita Puspita Sari is an alumna of Institut Teknologi Sepuluh Nopember (ITS). She got her bachelor and master degree from department of physics, ITS. After completing her Ph.D in Osaka university Japan, she have worked as a postdoc. researcher in Shibaura Institute of Technology. Her main research is on organic superconductor.
In addition to scientific introduction on her work, she also shared her experiences during her student life in Japan and encouraged other students in doing researches.
Department of Physics, Institut Teknologi Sepuluh Nopember and Synchrotron Light Research Institute (SLRI) Thailand organized a seminar entitled “Synchrotron Radiation Applications to ASEAN”. The seminar was held in Institut Teknologi Sepuluh Nopember on 27th of September 2017. Three invited speakers gave presentations related synchrotron light source facilities at SLRI. They are Dr. Siriwat Soontaranon, Dr. Wanwisa Limphirat and Dr. Chanan Euaruksakul.
Dr. Siriwat Soontaranon gave an introduction on synchrotron light source at SLRI and Small Angle X-ray Scattering (SAXS). SAXS is used to investigate nano structure of material such as analysis particle size and size distribution, percent crystallinity, starch lamellar nano structure and so on. Dr. Wanwisa Limphirat explained others facilities including X-ray absorption spectroscopy (XAS), Micro X-ray Fluorescence Spectroscopy/Imaging (XRF) and Infrared Spectroscopy and Imaging (IR). In the last session, Dr. Chanan Euaruksakul described on what Photoemission Electron Spectroscopy (PES) and Microscopy (PEEM) are and their functions to study materials.
SLRI offers foreigner users to apply a proposal to use those facilities. For more detail on the proposal applications and schedule can be found in the following webpage http://www.slri.or.th/en/
“The Muon Science: An introduction to a new research field for materials”
On Tuesday, 23rd of January 2018, advanced materials research group again held a guest lecture inviting Dr. Isao Watanabe from Advanced Meson Science Laboratory, RIKEN Nishina Center, Japan. The lecture was on the introduction of the muon science to study materials.
Muon is unstable elementary particle discovered in 1936 by Carl D. Anderson and Seth Neddermeyer as the secondary radiation from cosmic rays. It is simply a “heavy electron” with the mass of about 200 times heavier than that of the electron and also a “light proton” with the mass of about 1/9 of the proton. The muon carries the half spin and the large gyromagnetic ratio (2π × 13.55 kHz/G) which therefore acts as a very sensitive probe to study local magnetic fields. The muon spin polarizes after its production, and this self-spin-polarization can allow us to carry out experiments even in the zero-field condition. Muon’s spin and charge are exquisitely sensitive as a local magnetic probes of matter. A technique based on these unique properties of the muon is named as the μSR technique. μSR is an abbreviation of muon-spin rotation/relaxation/resonance. Low energy muons which are required for μSR are produced at intermediate energy particle accelerator facility. There are currently five facilities around the world producing muon beams: TRIUMF in Canada, ISIS in the UK, PSI in Switzerland and JPARC in Japan. μSR technique provides an excellent method to study materials in complement to the other experimental techniques.
by Thomas Hübert from BAM (Germany) at ITS (Indonesia)
On August 29th, 2016, Dr. rer-nat. Habil Thomas Hübert coming from the Federal Institute of Materials Research and Testing (BAM) – Germany gave a special lecture at Institut Teknologi Sepuluh Nopember (ITS) Surabaya – Indonesiawith the presentation title of “Gas Sensors for Technical Safety and Process Control“.
He had a chance to visit laboratories at Department of Physics – ITS and took photos with some members of Advanced Materials Research Group – ITS. He also enjoyed the travel to the so-called Sidoarjo mud flow or Lapindo mud.
This event shows a good partnership between ITS (Indonesia) and BAM (Germany).

Asia-Oceania Neutron Scattering Association (AONSA) is the neutron scattering societies representing users in the Asia-Oceania Region. AONSA was established in 2008. The purposes of the Association are to provide a platform for discussion and an action focusing on neutron scattering and related topics in the Asia-Oceania Region.
The 16th AONSA Executive Committee Meeting was held on Tuesday May 31, 2016, at the China Spallation Neutron Source (CSNS) in Dongguan, China. Eighteen participants came to Dongguan for the meeting, consisting of nine Executive Committee (EC) members and nine observers representing neutron facilities in the Asia-Oceania region. In this meeting, it was the first EC meeting to include the Indonesian Neutron Scattering Society (INSS) as a formal member of AONSA. In welcoming participants to the meeting, AONSA President Sung-Min Choi thanked the organisers in Dongguan, and extended a particular welcome to Darminto, representing INSS.
In this meeting, participants discussed briefly the preparations for the AONSA Young Research Fellowship in 2017, the 8th AONSA school to be held in India in November 2016, the International Conference on Neutron Scattering (ICNS2017) to be held in Korea in July 2017, and the 3rd Asia-Oceania Conference on Neutron Scattering (AOCNS-2019) to be held in Taiwanin November 2019. The meeting run smoothly. Finally, the next meetings will be held in India, Korea and Thailand for the 17th, 18th, and 19th AONSA EC meeting, respectively.
