Professor Yu Pu's group at the Department of Physics, Tsinghua University, in collaboration with the Soft X-ray Spectromicroscopy Beamline （BL08U1A）of the Shanghai Synchrotron Radiation Facility, has probed the two-dimensional electron gas on the surface of TiO2 material using XAS, in-situ electric transport, and electron microscopy, revealing the correlation/coupling properties between localized electrons and high mobility electrons.

Dr. Ye Li, Prof. Chuanyong Jing of Shandong University, and Associate Prof. Haixia Tian of Northwest A&F University, in collaboration with the Soft X-ray Spectromicroscopy Beamline （BL08U1A）of the Shanghai Synchrotron Radiation Facility, have utilized synchrotron radiation X-ray microscopy (STXM) and in situ XANES spectroscopy to conduct the in situ observation of the arsenic reduction process by the typical arsenic-reducing bacterium, Alkaliphilus sp. IMB, revealing that the reduction of pentavalent arsenic (As(V)) by IMB occurs at the cell membrane.
