NANOTEC researchers attended a NANO Talk session on “The application of synchrotron in nanotechnology” to better understand its application and explore ways to use synchrotron in their research activities. The speakers from Synchrotron Light Research Institute (SLRI) consisted of:
Dr. Supagorn Rugmai “Structural studies of nano materials with synchrotron light”
Dr. Chanapa Khongmark and Dr. Chanan Euaruksakul “Photoemmission electron microscopy with nano materials”
“Many measurement techniques are available for studies of nano materials, with each specific technique giving specific information on the materials” said Dr. Supagorn. “At nano scale, the material properties are usually complicated due to the interplay of various effects, contributing from atomic, molecular and larger scale structures. Structural information is therefore particularly important in understanding properties of the materials”.
Dr. Supagorn talk focused on three measurement techniques:
– Small Angle X-ray Scattering (SAXS): a technique particularly useful for nano structural characterization. The technique can give information such as sizes and shapes of nano particles and molecular arrangement in soft materials,
– X-ray Absorption Spectroscopy (XAS): a exclusive synchrotron technique where information on local atomic environment can be obtained.
– Photoemission Electron Microscopy (PEEM): a technique used to probe structures of surfaces. The technique can provide chemical and electronic information of surfaces with lateral resolution below 1 micron.
“Photoemission electron spectroscopy (PEEM) is suitable for measuring properties of materials as thin as one atomic or molecular layer” said Dr. Chana. “When using electron beam as an illuminating source, it is also possible to obtain additional information via measurement known as low energy electron microscopy (LEEM)”.
NANOTEC has been allocated the use of Beamline #5 at SLRI for research purpose. For information SLRI, please log on: http://www.slri.or.th/en/
NANO Talk is a monthly public forum organized by NANOTEC for researchers and visiting professors to exchange knowledge and be updated on technology trends. Visiting professors to Thailand are encouraged to participate. Please contact NANOTEC if you are interested in receiving updates or would like to recommend a speaker.
