Times Cited Count：10 Percentile：59.67(Materials Science, Multidisciplinary)The dynamics of titanium (Ti) melted by laser irradiation was investigated in a synchrotron radiation experiment. As an indicator of wettability, the contact angle between a selective laser melting (SLM) baseplate and the molten Ti was measured by synchrotron X-rays at 30 keV during laser irradiation. As the baseplate temperature increased, the contact angle decreased, down to 28 degrees at a baseplate temperature of 500
C. Based on this result, the influence of wettability of a Ti plate fabricated by SLM in a vacuum was investigated. It was revealed that the improvement of wettability by preheating suppressed sputtering generation, and a surface having a small surface roughness was fabricated by SLM in a vacuum.

Times Cited Count：54 Percentile：86.05(Physics, Nuclear)With upgraded detectors at the Relativistic Heavy Ion Collider (RHIC) and the Large Hadron Collider (LHC), it has become possible to measure hadrons beyond their ground states in high energy heavy ion collisions. Therefore, heavy ion collisions provide a new method for studying exotic hadrons that are either molecular states made of various hadrons or compact system consisting of muliquarks. Because their structures are related to the fundamental properties of Quantum Chromodynamics (QCD), studying exotic hadrons is currently one of the most active areas of research in hadron physics. The present review is a summary of the current understanding of a selected set of exotic candidate particles that can be potentially measured in heavy ion collisions.

Times Cited Count：23 Percentile：79.56(Physics, Nuclear)We report a half-life of the ground state of Re populated by the 
ReRe reaction with the laser Compton scattering -rays generated through relativistic engineering. The -rays are provided at the electron storage ring NewSUBARU. The previous experiment using deuteron-induced reactions has yielded a recommended half-life of the 3
ground state of Re to be 38.0 
0.5 d, including a possible contribution from the 8
isomer (
= 169 8 d) of Re since the presence of the isomer was not known at that time. In contrast, the reaction has an advantage to selectively populate the ground state because this reaction does not bring large angular momentum. The measured half-life of 35.4 0.7 d is shorter than the previous half-life by about 7%. This difference is crucial for applications using the activation method.

TiO
has been extensively studied because of high photocatalytic activity. However, the basic reaction process of photocatalysis has not been understood yet. In this study, the difference in water adsorption reaction between rutile and anatase was clarified using synchrotron radiation soft X-ray photoelectron spectroscopy (XPS). The OH component observed at the higher binding energy side was clearly confirmed in the rutile type TiOTiO, suggesting that the rutile type is more reactive to water adsorption.
