He was a research associate of Tohoku Univ. on April 1, 1988 and has then mainly been studying the synthesis and application of nanomaterials in Institute of Multidisciplinary Research for Advanced Materials (IMRAM). From April 2001, he is a Full Professor of Tohoku University and from October 2019, also a SRIS Director.

Role of Tohoku University for Next Generation Synchrotron Radiation
Facility, JapanThe Next Generation Synchrotron Radiation Facility (NGSR) is now underconstruction on our campus, New Extension of Aobayama, Tohoku University. The origin of the budget is both Japan Government and local partners consisted of local governments, Miyagi Prefecture and Sendai City, with Tohoku Economic Federation and Tohoku Univ.
Coalition concept is unique in use of NGSR mainly by private companies. The roles of Tohoku Univ. are mainly,
1) Leading academic research and industry-academia collaboration utilizing NGSR,
2) Construction of innovation system through industry-government-academia collaboration,
3) Formation of an international university synchrotron radiation alliance, and
4) Human resource development utilizing synchrotron radiation facilities.
For these missions, International Center for Synchrotron Radiation Innovation Smart (SRIS) was founded on October 1, 2019, in Tohoku Univ. I will introduce SRIS activities. For example, our SRIS team has been proposing 7 Coalition Beam Lines as a technical aspect of view.

Associate Professor, Synchrotron Radiation Research, Lund University

Jesper Wallentin’s research lies at the intersection of nanoscience and X-ray science. He develops X-ray methods to investigate nanostructured devices, in particular X-ray diffraction methods for in situ and operando investigations, but also imaging and fluorescence methods. In addition, he develops nanostructures as ultrahigh-resolution X-ray detectors. Jesper Wallentin has mainly worked with III-V nanowires, but in recent years also metals and metal halide perovskites. His research group has a strong collaboration with the Nanomax beamline at MAX IV, but also collaborates with other synchrotrons.

Synchrotron X-rays – a unique probe for materials science at the nanoscale
X-rays have always been used for their ability to analyze the inside of complete samples, without destructive preparation. With new synchrotron sources and modern X-ray optics, the relevant length scales for nanoelectronic devices can be reached. The MAX IV synchrotron in Lund, Sweden, is the world’s first fourth-generation synchrotron, offering orders of magnitude stronger coherent flux than previous generations. Here, I will briefly introduce the current and future capabilities of this facility, which is opens new opportunities for materials science in general and nanoscience in particular. Some examples from our research on III-V and metal halide perovskite nanostructures will also be shown.

X-ray Spectro-Ptychography: Visualization of Chemical State at Mesoscale
X-ray ptychography is a rapidly emerging technique at synchrotron facilities, which can non-destructively observe thick samples at the mesoscale. So far, we have developed the techniques for high-resolution and high-sensitivity hard X-ray ptychography using total-reflection mirrors as the X-ray focusing device at SPring-8 in Japan. The use of X-rays as a probe makes it possible to image both structures and chemical states through the absorption edges of a target element. X-ray ptychography using multiple energies including the absorption edge of a specific element, which is often referred to as X-ray spectro-ptychography, enables us to visualize the chemical state of nanostructures buried within thick samples. In this talk, I will introduce the results of visualizing the chemical state of three-way catalyst particles using X-ray spectro-ptychography, and explain the prospects for the next generation synchrotron radiation.

Current Status and activities of MLF of J-PARC
Materials and Life Science Experimental Facility (MLF) of Japan Proton Accelerator Research Complex (J-PARC) provides world’s most intense neutron and muon beams with the MW-class proton accelerator. More than 10,000 international users visit MLF annually to perform wide range of academic and industrial research. Our mission is not limited to provide user program with existing state-of-the-art instruments but also to explore the possibilities of neutrons and muons. Thus, developments of instruments, detectors, optical devices, analysis software and targets systems of neutron and muon are on-going. To promote such broad activities, it is essential to collaborate with researchers outside of MLF. In this presentation, current status and activities of MLF of J-PARC will be reviewed.

Opportunities for materials science at compact accelerator driven neutron sources
Neutrons offer unique opportunities in materials research as they are a non-destructive bulk probe with down to atomic resolution and sensitivity to isotope labeling, low energy excitations and magnetic induction. However, other than x-rays or electrons neutrons for materials research are almost exclusively available at large research centers. This is related to the fact that neutrons are produced at high energies and need moderation. At ultra compact accelerator driven neutron sources (UCANS) neutrons are produced at lower energies allowing a compact design of the source. Moreover, as no large facility is required the neutron source can be designed according to the needs of the scientific question with significantly improved brilliance transfer and at considerably lower costs. This allows the construction of small dedicated local facilities serving specific needs. In this talk I will outline the concept of UCANS and explain its applicability in science, with a focus on materials research.

Energy Conversions in Nanoscale
The efficient use of the light energy is one of the important issue toward energy society. It is known that metal nanoparticles can confine the light energy at the nanoscale region via the excitation of the localized surface plasmon resonance (LSPR). We are working on the unique light-matter interactions at the nanoscale interface based on the “Physical Chemistry” and “Electrochemistry”,  especially for strong coupling states to generate novel hybridization between photons and excited electrons in materials.

Following graduation, he coordinated the startup of Pronano AB, a nanotechnology research institute. He was later recruited to Sol Voltaics AB, to build a team around nanowire-based solar cells; here, he co-invented the Aerotaxy technology. He returned to Lund University as associate professor in 2013 and continues Aerotaxy research. He is also director of studies for the five-year Engineering Physics MSc program, and deputy head of the department of Physics.

Aerotaxy – mass produced nanowires with sensor applications
Mass production of nanowire materials in the aerosol phase, Aerotaxy, has been demonstrated with excellent control of wire size, shape and material. So far, we can grow wires in the GaAsP system, up to 2.5 μm in length and 10 to 120 nm in diameter, and with cylindrical, conical or branched shapes. The production rate in a simple lab scale reactor is up to 1 mg/h with no need for lithography or substrates. Still, Aerotaxy is somewhat of a solution in search of a problem. The wires are produced as a disordered powder, while most applications require ordered arrays. One such application is presented in more detail, where the wires are vertically aligned post growth to form an optical single molecule biosensor.

He started his postdoctoral research at Sophia University in Professor Takashi Hayashita’s group as JSPS Research Fellowship for Young Scientists PD. His current research focuses on boronic acid-based chemosensors and supramolecular chemistry.

Design of ortho‑Azophenylboronic Acids for Colorimetric Saccharide Chemosensors from a Perspective of Mechanistic Study
Many boronic acid-based saccharide chemosensors have been developed, however, most of the sensing mechanisms remain unclear. Herein, we synthesized a series of ortho-azophenylboronic acids (azoBs), a representative structure for colorimetric sensing of saccharide, and reinvestigated the sensing mechanism toward D-fructose.
UV-vis and 11B NMR spectral studies indicated that azoBs form a quasi-tetrahedral species that was inserted by a protic solvent molecule. This species exhibits a red-shifted UV-vis absorption spectrum from the other species of azoB. We concluded that the drastic color change of azoB in the reaction with saccharide is ascribed to the release of the inserted solvent molecule from the quasi-tetrahedral species of azoB.
Based on the findings, we proposed a guideline for designing the structure of azoB that shows a large color change by the reaction with saccharide and a high affinity toward saccharide.

Multifunctional nitride and oxide thin film for thermoelectrics and energy harvesting
Thermoelectric devices have the potential to contribute to energy harvesting in society by directly converting heat into electricity or vice versa. However, the conversion efficiency of thermoelectric devices of today is limited. In this invited lecture, I present an overview of our work on CrN-, ScN-, and Ca3Co4O9-based thin films. We have introduced a two-step sputtering/annealing method for the formation of highly textured virtually phase-pure Ca3Co4O9 thin films. These can further be deposited on flexible mica substrates, enabling flexible inorganic thermoelectric thin films that withstand repeated bending. They can also be made as free-standing films and as nanoporous materials for reduced thermal conductivity. ScN thin films exhibit an anomalously high power factor (S2/r) for transition metal nitrides, but has high thermal conductivity, thus its ZT is low (~0.2). To reduce lattice thermal conductivity, potential strategies are nanostructuring, alloying or nanoinclusion formation. Pure CrN exhibits n-type conduction with a high power-factor enabled by a high electron concentration thermally activated from N vacancies, and alloys can be made of rocksalt-Cr1-xScxN. We have demonstrated that it can be rendered p-type by Al alloying in combination with N superstoichiometry.

Electron Microscopy Study for Radiation Damage in Oxide Ceramics
Fundamental understanding of radiation-induced defects is essential for the search and development of radiation-resistant nuclear materials used under harsh environment with radiations. This presentation reports electron microscopy investigations of the structure and nucleation-and-growth process of defects in fluorite-type oxide ceramics. Important role of synergistic effects with elastic displacement damage and electronic excitation, and elective displacement damage in oxygen ions will be shown through a variety of electron microscopy techniques, such as atomic scale observation/analysis, in situ microstructure observation and spectroscopy, etc. The Ultramicroscopy Research Center of Kyushu University will be also introduced in the presentation.

Radiation hardness of thin film solar cells
Thin film solar cells have advantages over crystalline silicon solar cells due to reduced materials and energy need in production, and possibility for flexible and lightweight products. The two main commercial technologies, CdTe and Cu(In,Ga)Se2(CIGS), have both demonstrated efficiencies in the lab of over 23%, as compared to 26% for c-Si. Cu2ZnSnS4 (CZTS) is studied as a potential alternative material based on only abundant and non-toxic elements. A well-known property of CIGS is the radiation hardness, giving potential for space-applications. Our initial studies of the radiation hardness of CZTS, using proton and electron irradiation, showed equal or superior hardness, including strong self-healing. Possible reasons for this behavior will be discussed.
