This article introduces ideas and practices behind Kyoto University's Open Access Policy established in April, 2015. Kyoto University was the first Japanese university that implemented open access (OA) policies to make its scholarly articles freely accessible. This implementation has garnered wide media attention, encouraging other research universities to follow the same action. The article describes basic ideas behind Kyoto University's OA policy as well as recent developments in Japan. It also discusses what obstacles Japanese universities encounter as they endorse OA policy against multiple stakeholders in the academic publishing industry. It finally suggests what can be done to improve the whole OA system, especially in relation to potential conflicts over copyrights between universities and academic associations.

The morphology and friction coefficient associated with water content and lipid on the skin of the inner part of the forearm, were investigated in 250 healthy subjects. It was found by electron microscopy that skin surface exhibited a pattern formed by two types of stripes, main stripes and fine stripes and these differ in length and depth from the superficial surface of the skin. Total length of the stripes on the skin surface per unit area decreases gradually with age of subject, and the pattern of the skin surface in advanced age is mainly formed by the main stripes. Friction coefficient of the surface depends largely on the total length of the stripes per unit area. It increases monotonically with the decrease of the total length.The relationship was investigated between water content and friction coefficient on skin surface, and it was found that there was an optimum water content to minimize friction coefficient of the skin surface.

Since large amounts of radioisotopes of Cs was released after the accidents at Fukushima Daiichi nuclear powerplants, a tremendous number of scientists and engineers have faced several issues in terms of decontamination ofradioactive Cs. In this paper, we present our recent two computational works based on density functional theory, one of which is to clarify mechanism of strong adsorption and retention of Cs in clay minerals to establish an effective Cs removal scheme from large amounts of radioactive wastes left by decontamination activities, and the other of which is to reveal why zeolites can selectively catch Cs even in the presence of other minerals and to make a guideline to create a more improved materials to remove Cs as well as other radioactive ions.

We review the recent progress of the study of silicene, which is a honeycomb structure of silicon atoms. Silicene shares many similar properties with graphene but has some extra exciting properties since it is a topological insulator due to its spin-orbit interactions. Silicene has so far been synthesized only on a substrate. The synthesis and the measuring physical properties of silicene are interesting playgrounds of the surface science.

An odor recorder for recording recipe of smell as well as reproducing it has been developed. It includes an array of sensors with partially overlapping specificities, odor blender and its recipe modification algorithm implemented in a computer. In the odor recorder, the recipe of the blended odor is iteratively modified so that the output pattern of the blended odor can agree with that of the target odor. The real-time reference method was developed to suppress the influence of the environmental change and to record the dynamical change of the odor. The target and blended odors are alternately supplied to the sensors and the recipe of the blended odor is adjusted so that the difference of the sensor responses between the two can be minimized. The dynamical change of the recipe of the four component odors in the apple flavor was successfully recorded without the influence of the environmental disturbance such as temperature and humidity changes.

In order to elucidate the difference of the mechanisms of imaging between scanning tunneling microscopy (STM) and non-contact atomic force microscopy (NC-AFM), the atomic structure and local physical properties of SrTiO3(100) surface were studied by using STM and NC-AFM. We theoretically simulated a model cluster with first-principles total energy calculation. Calculated density of states (DOS), work function, images for STM and NC-AFM were in good agreement with experimental data.

For large area coating of architectural glass work with excellent quality and performance of self-cleaning, the sputtering method is suitable for the thickness uniformity and the appearance. Usage of a seed layer is illustrated to form the anatase structure of TiO2. The coating shows the good photo-activity and the excellent self-cleaning performance. This seed layer effectively makes the incomparable lattice matching to the anatase TiO2. Finally, it was found that the double side sputtering with high performance LowE coating is real process when the seed layer is utilized.

It was found that the key points of time reduction of bobsleigh were to reduce friction resistance between the runner and ice, and to improve the start technique, from the results of bobsleigh's dynamic analysis. Then, the authors designed and manufactured a new bobsleigh runner based on elastic-plastic contact analysis, which realized minimum contact area between the runner and ice within the shape that prevents ploughing term in friction force. The developed bobsleigh runner based on the analysis was named as “Nagano Special”. Additionally, the authors suggested a new start technique called “Keri-Nori”, which was quite different from the conventional start technique of the Japanese bobsleigh team, and verified its benefit. By using the newly developed bobsleigh runner “Nagano Special” and the new start technique “Keri-Nori”, the Japanese bobsleigh team took the 4th place among the world 44 teams in the international official tryout held on February 1998 just before Nagano Olympic Games.

Highly oriented pyrolytic graphite treated with NaOH solution was found to form a stage-8 intercalation compound. Superstructures such as 2x2, √3×√3 and noble orthorhombic lattices were observed on the surface, as previously observed on the surfaces of the stage-1 M-GIC (graphite intercalation compound, M=Li, K, Rb, Cs). On the contrary, substrate lattice structure was observed on NaOH-treated MoS<SUB>2</SUB>. In addition, new structures near the Fermi level were found to be formed by NaOH-treatment on the surface.

The electronic structures of many materials can be well described by the one-particle picture within the band theory. A quantitative evaluation of band gaps in semiconductors and insulators, however, needs special care because the subtle balance between the exchange and correlation effects must be properly taken into account. This article reviews theoretical approaches for calculating band gaps of materials based on 1) many-body perturbation theory, 2) density-functional theory, and 3) wavefunction-based theory, and the advantages and of each theory disadvantages are discussed.

The core-level-excitation-induced ion desorption from surface is investigated. Two studies using electron-ion coincidence spectroscopy are shown. On Si(100)/H2O surface, it is shown that ion desorption is mainly induced by the shake-up/off excitation accompanying the Auger decay when the photon energy is near the O1s threshold. At a photon energy higher than the shake-up threshold, most of ions desorb resulting from the shake-up excitation accompanying the core-excitation. In both cases, the desorption is induced by the multi-hole final state. On ice surface, the kinetic energy of O1s photoelectrons gives the highest coincidence yield of H+ desorption is shifted by about −0.7 eV compared to the O1s peak observed in the conventional core-level photoelectron spectroscopy. It is ascribed to a core-level shift in the O1s level from which hydrogen ions desorb.

Palladium absorbs hydrogen exothermically. Under the industrial conditions for hydrogenation reactions over palladium catalysts, palladium particles should be working as palladium hydride α'-PdHx (x > 0.6), which suggests the enrollment of absorbed hydrogen in the hydrogenation reaction. In this article, after the energetics, kinetics, and microscopic mechanism of the hydrogen absorption and release processes on palladium surface is reviewed, the recent research on the role of absorbed hydrogen on the alkene hydrogenation reaction on palladium is briefed.
