Friday, 21 Oct. 2022
Osaka time: 16:00-18:00
Groningen time: 9:00-11:00
Chair: Prof. Tadashi ItohProf. Yoshitada Morikawa, Graduate School of Engineering (16:00-16:55 (O) / 9:00-9:55(G))(Field: computational science, surface science, DFT, machine learning, CO2 hydrogenation)
Title: Computational Materials Design for Surfaces
Abstract: Chemical reactions at surfaces and interfaces play important roles in wide ranges ofapplications such as heterogeneous catalysis, electrochemistry, fuel cells, batteries, etchingprocesses of semiconductor materials, and so on. In this lecture, I will present density functional
theory (DFT) investigation and prediction of hydrogenation of CO2 over Cu catalyst. To clarify
reaction mechanisms and to identify important factors governing the reactivity of CO2 on solid
surfaces are very important to develop more efficient catalysts or catalytic processes for utilizationof CO2. Although DFT simulations are quite useful to investigate atomic-scale phenomena, the1time scale of the simulations is limited to tens of ps and the length scale to nm. I will discuss
how to extend the length-scale and time-scale of DFT simulations by combining DFT calculations
with machine learning techniques. I will show that it is now possible to clarify the formation
process of Cu–Zn surface alloy, which has been extensively studied for the clarification of the trueactive site of Cu/ZnO/Al2O3, the industrial catalyst for methanol synthesis which remains undercontroversy.

Prof. Jagoda Sławińska (speaks 10:00-10:55 (G) / 17:00-17:55 (O))(Field: computational materials science, spintronics)
Title: Spin-orbit-related phenomena for energy-efficient electronic devices
Abstract: In this lecture, I will discuss the fundamentals of spintronics (spin-based electronics)
which employs the electron’s spin, along with its charge, to carry and process information in amore energy-efficient way. Spin-orbit interaction, despite being small in magnitude, is very
powerful and drives several intriguing phenomena that allow for different functionalities suitable
for novel electronic devices. After explaining the basic principles and challenges of spintronics, I
will focus on materials for conversion between charge and spin currents and their computational
design via first-principles calculations.

Friday, 28 Oct. 2022
Osaka time: 16:00-18:00
Groningen time: 9:00-11:00
Chair: Prof. Tadashi ItohProf. Yasufumi Fujiwara, Graduate School of Engineering (16:00-16:55 (O)/ 9:00-9:55 (G))(Field: rare-earth-doped semiconductors, OMVPE growth, LED, luminescence, energy transfer)
Title: Fundamentals of light-emitting diode with rare-earth-doped semiconductors
Abstract: After the groundbreaking invention of blue and green light-emitting diodes (LEDs)
employing nitride semiconductors (InxGa1-xN/GaN), there has been a strong demand to develop
red LEDs using nitride semiconductors. We have focused on europium (Eu) ions that have been
widely used as an activator for red phosphor, and have succeeded in growing Eu-doped GaN(GaN:Eu) layers with high crystalline quality by atomically-controlled organometallic vapor phase
epitaxy (OMVPE), as well as developing the world’s first red LED that operates at room
temperature using GaN:Eu as the active layer. This lecture will cover current status ofconventional GaN-based LEDs and the GaN:Eu red LED, present understanding of Eu
luminescent sites formed in GaN and future strategies for the improved light output of the LEDs.

Prof. Rifka Vlijm (speaks 10:00-10:55 (G) / 18:00-18:55 (O))(Field: super-resolution microscopy, STED, STORM, MINFLUX)
Title: Super-resolution light microscopy
Abstract: For decades it was believed that light microscopy could not be used to discern structures
closer together than the diffraction limit (half the wavelength of light ~250nm). With thegroundbreaking invention of STimulated Emission Depletion microscopy, and later STORM(Stochastic Optical Reconstruction Microscopy) and other methods, now it became possible tovisualize even in living cells structures much smaller than the wavelength of the used light. The
latest development (MINFLUX nanoscopy) even allows imaging in living cells with an effective2

point spread function of only a few nanometers. In this lecture the working principles ofsuper-resolution microscopy techniques are explained, and the benefits and drawbacks of each ofthese are discussed. By identifying the bottlenecks of our methods a suitable match between
research question and applied technique can be made. Furthermore, by identifying whichbottlenecks are technical rather than fundamental, new developments can be stimulated. We here
discuss some of the latest developments significantly driving the field of light microscopy.

Chair: Prof. Tadashi ItohProf. Yasuhiro Nakazawa, Graduate School of Science (17:00-17:55 (O) /9:00-9:55(G))(Field: Molecular superconductors, electron correlations, thermodynamics)
Title: Molecular superconductors and their thermodynamics
Abstract: The organic-molecules-based conductors and superconductors give a variety of physicalfeatures of itinerant -electrons released from molecular orbitals. Fascinating physical andchemical features related to the electron correlations, electron-phonon interactions emerge in themwith various manners, since the energy scale of spin, charge, and phonon degrees of freedom are in
the similar order. The lecture focus on why the interesting conducting states, especiallysuperconductivity with unconventional characters appear in them and how we can characterize the3electronic properties by means of micro-crystal thermal measurements.

Prof. Loredana Protesescu (10:00-10:55 (G) / 17:00-17:55 (O))(Field: nanomaterials)
Title: Functional inorganic nanomaterials
Abstract: As a special class of materials, inorganic nanomaterials consist of particles of metals,
metal oxides, metal chalcogenides (metal sulfides, selenides, or tellurides) or halide perovskites
with at least one dimension in the 1- to 100-nanometer (10−9 m) range. These nanomaterials arehighly interesting because they exhibit properties that bridge the gap between bulk and molecular
structures. Unlike their bulk counterparts, nanomaterials exhibit tunable size- and shape-dependent
optical, electronic, and magnetic properties. Because of these unique properties, nanomaterials arebeing explored to address key global challenges in areas such as energy conversion, catalysis,
medicine, sensing, and environmental remediation.
