There were about 500 people in attendance.

TItle： Correlation Between High Gas Sensitivity and Dopant Structure in W-doped ZnO Authors：Shun Fukami, Munetaka Taguchi, Yutaka Adachi, Isao Sakaguchi, Ken Watanabe, Toyohiko Kinoshita, Takayuki Muro, Tomohiro Matsushita, Fumihiko Matsui, Hiroshi Daimon and Taku T. Suzuki Journal：PHYS. REV. APPLIED 7, 064029 (2017) pp1-6 HP：https://doi.org/10.1103/PhysRevApplied.7.064029 (abstract) Zinc oxide is a representative material which widely used as solid-state gas sensors. However, the local atomic structure around dopant site and these segregation mechanism is not fully understood. The authors find clear evidence for substitution of segregated W atoms into Zn sites in the subsurface layer by photoelectron diffraction techniques, which drastically improves the sensing response. This surface’s structure-function relationship could tell us about how best to prepare these films for this important gas sensing application.

2017/3/13-15 The users meeting of MAX IV was held in Lund, Sweden. Some of the members attended to the meeting. After the meeting, the members visited MAX IV and discussed with Dr. Christoph Quitmann (Director of MAX IV) and other beamline staff members, especially about the future collaboration and organization of joint workshop held in October.

One of the target of “3D-active site project” is to promote international collaborations. We consider that MAX IV, most brilliant synchrotron light source, in Sweden can be a candidate of the oversea basement of our project. For future collaboration between European scientists and Japanese members, we plan to organize the joint workshop in October. 

On March 13-15, the users meeting of MAX IV was held. Some members of our project attended to the meeting in order to obtain the detailed information and status of MAX IV. The emittance smaller than 1nm・rad is designed, and the facility was opened from June in 2016. Some user’s activities seem to be started. There are two storage rings, with acceleration energy of 1.5 and 3GeV. About 300 participants attended and the satellite workshops for industrial use etc were held. 

The commissioning of storage rings seems to be well. In the 3GeV ring, storage current up to 200mA was achieved. 24 hours topping up injection is also successful at the storage current of 160mA. The emittance of 340pm・rad was also achieved when the storage current is a few mA. 5 insertion devises has been installed. Single bunch operation of 2.8mA (maximum 8.5mA) was succeeded. For 1.5GeV ring, 135mA topping up operation is possible (maximum 150mA). 

Two beamlines (nanoMAX and BioMAX) which are hard-x-ray beamlines has started their first user’s beam time. Next proposal will soon be accepted. In the soft-x-ray region, ambient pressure photoemission and RIX beamlines are now in under commissioning. 
 
In MAX IV, ~3000 users/ year will visit and ~500 publication is expected. Further ~100 PhD papers will be produced. In the initial stage, the budget for 14 beamlines is approved. Plans of up to 22 beamlines are discussed. 
 
The guesthouse with 21rooms will be available in September 2017. 

The neutron beam facility so called ESS is under construction nearby MAX IV. ESS will start their beamtime in 2023 and the construction will be completed in 2025.

After the users meeting, some members of “3D active-site” project (Daimon, Hayashi, Matsui and Kinoshita) visited MAX IV. Members obtained detailed information of some related beamlines at MAX IV and presented status and activities of the project. Especially, the proposal to NanoMAX beamline was discussed. Further, the detailed discussion of the joint workshop held in October was discussed.

Inverse Ubbelohde effect in the short hydrogen bond of photosystem II: Relation between H/D isotope effect and symmetry in potential energy profile Yusuke Kanematsu, Masanori Tachikawa, and Yu Takano Journal of Computational Chemistry 37, 2140-2145 (2016). http://onlinelibrary.wiley.com/doi/10.1002/jcc.24438/abstract Cover Page : http://onlinelibrary.wiley.com/doi/10.1002/jcc.24458/full The short hydrogen bond between tyrosine Yz and D1-His190 of photosystem II (PSII) is involved in the oxidation of water at the Mn cluster. We investigated the short hydrogen bond, using multicomponent quantum mechanics, where the quantum fluctuation of a hydrogen nucleus was incorporated into electronic structure calculation. Our computation demonstrated that the deuteration for hydrogen in the short hydrogen bond of PSII led to the reduction of the O…N distance. It indicated an inverse Ubbelohde effect typically recognized in strong and symmetric hydrogen-bonding clusters such as FHF– and H­­­­­­3O­2–.
