Lecture 1
 
Friday, 21 Oct. 2022
Osaka time: 16:00-18:00 JST
Groningen time: 9:00-11:00
 
Chair: Prof. Tadashi Itoh
Prof. 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 of applications such as heterogeneous catalysis, electrochemistry, fuel cells, batteries, etching processes 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 utilization of CO2.  Although DFT simulations are quite useful to investigate atomic-scale phenomena, the 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 true active site of Cu/ZnO/Al2O3, the industrial catalyst for methanol synthesis which remains under controversy.
 
Chair: Prof. Remco Havenith
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 a more 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.

Lecture 2
 
Friday, 28 Oct. 2022
Osaka time: 16:00-18:00 JST
Groningen time: 9:00-11:00
 
Chair: Prof. Tadashi Itoh
Prof.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 of conventional 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.
 
Chair: Prof. Thomas Jansen
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 the groundbreaking invention of STimulated Emission Depletion microscopy, and later STORM (Stochastic Optical Reconstruction Microscopy) and other methods, now it became possible to visualize 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 effective point spread function of only a few nanometers. In this lecture the working principles of super-resolution microscopy techniques are explained, and the benefits and drawbacks of each of these are discussed. By identifying the bottlenecks of our methods a suitable match between research question and applied technique can be made. Furthermore, by identifying which bottlenecks 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.

Lecture 3
 
Friday, 11 Nov. 2022
Osaka time: 17:00-19:00 JST

Chair: Prof. Tadashi Itoh
Prof. Syoji Ito, Graduate School of Engineering Science (17:00-17:55 (O) /9:00-9:55(G))
(Field: laser manipulation, single-molecule detection)
Title: Single-molecule fluorescence detection: methods and applications
Abstract: The lecture starts with the history of single-molecule fluorescence detection (SMFD) and the introduction of typical methods of SMFD: confocal and wide-field microscopies. Then several important applications of SMFD are shown, e.g. fluorescence correlation spectroscopy, single-molecule tracking, and super-resolved fluorescence imaging.
 
Chair: Prof. Thomas Jansen
Prof. Jan Anton Koster (10:00-10:55 (G) / 18:00-18:55 (O))
(Field: Photophysics and optoelectronics, semiconductors and devices, thermoelectrics)
Title: Organic semiconductors for thermoelectrics
Abstract: In this lecture, I will introduce organic semiconducting materials and will briefly review their charge transport properties. Next, I will emphasize their promise for thermoelectric applications.

Lecture 4

Friday, 18 Nov. 2022
Osaka time: 17:00-19:00 JST
Groningen time: 9:00-11:00 (in winter time)

 
Chair: Prof. Tadashi Itoh
Prof. 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 physical features of itinerant p-electrons released from molecular orbitals. Fascinating physical and chemical features related to the electron correlations, electron-phonon interactions emerge in them with 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, especially superconductivity with unconventional characters appear in them and how we can characterize the electronic properties by means of micro-crystal thermal measurements.
 
Chair: Prof. Thomas Jansen
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 are highly 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 are being explored to address key global challenges in areas such as energy conversion, catalysis, medicine, sensing, and environmental remediation.
