Ik Jin Kim, In 1992 he earned his Dr.-Ing at GHI, Technical University of Aachen, RWTH, Germany. Since March 1994, he is a Professor at the Department of Materials Science and Engineering at Hanseo University, and concurrently director of the Institute for Processing and Application of Inorganic Materials(PAIM). He was the director of the Institute of Advanced Ceramics for Semiconductor (IACS) at BIEMT Ltd. He is the author and co-author of over 250 journal publications and presented numerous international conference papers. From 2007-2008, he was a guest Professor at ETH in Zurich, Switzerland.


A novel approach towards the formation of carbon nanotubes (CNTs) onto biomorphic carbon membrane was attempted by the application of three different reaction techniques. Carbon membranes having pore dimensions of 20-25μm were developed using carbonizing reaction. Template crystals (LTA, Silicalite, mesoporous SiO2 etc.) were simultaneously synthesized and coated within the biomorphic carbon materials(BCM) by an in situ hydrothermal process and were subjected to a simple ion loading reaction for preparing the suitable catalyst material for carbon nanotube-filters. The carbon nanotubes were grown directly upon biomorphic substrates. The CNTs were seen to have grown as bush-like structures creating a close network inside the pores of the ceramic substrate. The HRTEM images that were obtained at 700 °C show a considerably thicker wall thickness and the widest hollow-inner-tube structure, whereas those of the CNTs that were obtained at 650 °C show a comparatively thinner outer wall and narrow inner-tube structure with smooth walls. The maximum carbon yield is 23,71 % for the reaction time of 180 min; This CNTs nano-filter can be used for filtration of gases and has significant filtration efficiency without pressure drop, which is because the carbon nanotubes function as the trap of gas molecules.

Conference Series Materials Summit 2019 International Conference Keynote Speaker Taro Uematsu photo

Taro Uematsu got Ph.D from Osaka University in 2010 and he has been working for nanomaterials related to semiconductors and metals. He was interested not only in materials themselves but also photoelectrochemical aspects of nanomaterials, more specifically, photoinduced electron transfer and the resulting emission quenching of semiconductor quantum dots. He has been published several papers on the surface chemistry of quantum dots. His findings of band edge emission from cadmium free quantum dots are based on these perceptionsa


Semiconductor nanoparticles (quantum dots, QDs) are photoluminescent materials represented by cadmium sulfide and selenide, and they have recently been applied to the color conversion materials used in display devices. Despite their prominent monochromaticity, the use of cadmium compound is no longer allowed for commercial products, and alternative nanoparticle materials like III-V semiconductors (InP and GaP) and I-III-VI ternary semiconductors (CuInS2 and AgInS2) have been proposed.

The paper reports, for the first time, a narrow band edge emission from the AgInS2 ternary semiconductor QDs, which had been developed by our group as photoluminescent QDs but obtained a spectrally broad defect emission (fwhm = 200 nm). We focused on the surface of QDs rather than core crystals, since surface is as equally important as inside for the nanoparticles less than 10 nm. The direct factor for the successful observation of band-edge emission from the ternary material was surface passivation by III-VI semiconductors, indium and gallium sulfides (InSx and GaSx). Actually, core/shell structure has often been made using zinc sulfide as a shell, since it is an easily crystallize wide gap material (E = 3.7 eV); however, it seemed not be suitable for passivating group 11 and 13 elements due to the mismatch of valency at the interface between core and shell.

The narrow photoluminescence (fwhm ~ 35 nm) was successfully obtained, and photoluminescence quantum yield around 10% in the beginning of the research was improved by overall modifications to the synthetic procedures. The core AgInS2 nanoparticles of ca. 4 nm with tetragonal crystal structure prevented nonradiative relaxation pathways in the core crystal. The thickness of GaSx shell was increased by using more reactive sulfur sources. Finally, surface passivation of GaSx shell by alkyl phosphines improved the quantum yield to 56%

The thermoplastic elastomer having the hard segment and the soft segment can be remolded by heating. The thermoplastic elastomer is a polymer having both the thermoplastic and elastic properties as a rubber-like polymer. Recently, it has been used in industrial fields for many purposes such as packaging containers, automobile interior materials, and elastic fibers, and the demand thereof is greatly increased because of easy recycling and processing.  In this study, the thermoplastic polyetherester elastomer (TPEE) which can improve the environment friendliness by incorporating Isosorbide derivative derived from biomass in the soft segment and control the melting point easily while maintaining the elastic and physical properties of the thermoplastic elastomer was synthesized and characterized. The crystallinity, thermal stability and melting temperature of TPEE containing ISB derivatives were observed by DSC, TGA and POM

In vivo study mechanical properties of facial skin, mainly composed of epidermal, dermis and hypodermis, especially the development of experimental devices and the optimization of experimental methods is very important. In this paper, a set of facial skin and soft tissue mechanical properties measurement equipment is developed, which is composed of indentation and friction device and properly combined with three cameras CCD. One CCD connected transparent indenter is used to observe the contact area and the topography of the test area. The other two acquire the image around the test area during the experiment, and then obtained the deformation field by using digital image correlation technology. This device can not only obtain the force-displacement curve, but also observe the morphology of the test area and the deformation of the surrounding test area. It can be obtained the mechanical properties of the facial soft tissue more accurately. Compared with the formulas in classical Hertz theory, the contact force calculated by the new formula is in better agreement with the experimental results. We performed the in vivo indentation tests on human facial skin to evaluate the Young’s modulus. A better understanding of the adhesive behavior of human facial skin is important for dermatological or cosmetic applications. The real contact radii of human facial skin under different conditions was obtained by indentation experiments on the six volunteers and their adhesive behavior is studied. Except the adhesion forces under different conditions, we also compared the theoretical adhesion energy and theoretical debonded radius with the experimental results. Considering that hyperelastic model is usually more suitable for skin research, we revise the classical elastic adhesion theory (JKR theory) based on Neo-hookean model, and the contact radii obtained by the modified hyperelastic adhesion theory model shows a better agreement with the experimental values.

We investigated the effect of cobalt doping on band offset between ZnO and CuO  in nanostructured ZnO/CuO heterojunction solar cells. The band offsets between Zn1-xCoxO (x=0, 0.05, 0.1, 0.15, and 0.20) and CuO nanostructures was calculated from X-ray photoelectron spectroscopy (XPS) measurements. We observed that the conduction band of Zn1-xCoxO moves closer to the vacuum level with the increasing value of cobalt doping (x), leading to a decrease in the conduction band offset between Zn1-xCoxO and CuO and hence an enhancement of the open circuit voltage. Photovoltaic devices with 10% Cobalt-doped ZnO exhibited the best power conversion efficiency of 1.87%. The performance of the fabricated solar cells is discussed as a function of conduction band offsets with doping. Correspondingly, it was demonstrated that the insertion of a thin film of molybdenum oxide (MoO3) between the CuO active layer and the gold contact inhibits the formation of a Schottky junction. By inserting a MoO3 layer on the absorbing CuO layer, we enhanced the conversion efficiency of the 10% Cobalt doped ZnO-CuO solar cell to 2.11. A detailed analysis of the influence of MoO3 buffer layer thickness on the current-voltage (I-V) characteristics of devices will be presented.

The latest developments and the main achievements in the field of inorganic fullerene-like (IF) nanoparticles and nanotubes (INT), which were discovered by the Tenne group of the Weizmann Institute of Science in 1992, will be shortly presented. We consider some aspects of synthesis, structure and properties of the closed-cage nanoparticles that were studied over the about three decades using different modern experimental techniques (HRTEM, SEM, XRD, etc.) as well as advanced theoretical approaches. Elucidating the growth mechanisms of different kinds of the nanoparticles allowed us achieving substantial progress in the synthesis of INT and IF nanoparticles of WS2 and MoS2 including pure and doped, e.g. by Nb atoms, and many other layered compounds.

Rising interest to this kind of materials has been accomplished in the use of such nanoparticles for tribological applications and lately for impact resilient nanocomposites. The tests indicated that IF-MoS2 and IF-WS2 are heading for large-scale applications in the automotive, machining, aerospace, electronics, defense, medical and numerous other kinds of industries. In view of their eminent applications potential, much effort and substantial progress has been achieved in the scaling-up of the synthesis of inorganic nanotubes and fullerene-like nanoparticles of WS2 and MoS2 and also other compounds. A few products based on these nanoparticles have been commercialized by “ApNano Materials, Inc” (“NanoMaterials, Ltd.”, see also

Innovative materials and manufacturing technologies have led to significant progress in vehicle lightweighting over the past two decades. But difficulties to implement these technologies in medium to high volume vehicles have been hindered, mainly by higher costs and environmental impacts associated with the use of new lightweight solutions at various steps in the manufacturing process.
Aiming at promoting lightweight technologies to the next level and a rapid transfer of innovations into series production, the Affordable Lightweight Automobiles Alliance (ALLIANCE) is a research project that investigates some key factors and process steps in lightweight development. It aims to develop novel advanced materials and production technologies that enable an average weight reduction of 25%, on a production of 100k units per year, at a cost of <3 €/kg. Many systems in development consist of a single component such as housings and structural parts. Here the Target Weighing Approach is less feasible and gets extended by capabilities to analyse an existing product generation with one to few components. The dimensions mass, CO2 footprint and cost are key factors for the Extended Target Weighing Approach to also evaluate concepts on new product generations to select the most suitable design for the desired functions under consideration. Advanced support tools have been developed accelerating the design and evaluation process. Advanced materials with much better performance are ready for upscale. A reduction in GWP is higher than the formerly expected -6%. Weight targets on full vehicle level of -21-33% will be achieved.

Jianyi Liu has completed his B. A. in optical information science and technology in 2011 and Ph. D. in condensed matter physics in 2017 from Sun Yat-sen University under the guidance of Prof. Yue Zheng. During 2015 and 2016, he worked as a research assistant in the group of Prof. C. H. Woo in City University of Hongkong. After completion of his degree, Jianyi Liu continued his work in Prof. Zheng’s group as a postdoc, where he is focusing his research efforts on dynamics of polarization in ferroelectric nanostructures.


Controlling ferroelectric toroidal order in ferroelectric nanostructures, which is central to cashing out its numerous application prospects, has triggered intense interests nowadays. Great efforts have been made in pursuit of switching the chirality of ferroelectric toroidal order by an experimentally feasible way in the past decade. However, being quite different with the traditional ferroelectric domain patterns, the controllability of ferroelectric toroidal order is hindered by its toplogical feature. The strategies of vortex switching reported in the literature recently are to introduce a region of “dominant dipoles” during nucleation in ferroelectrics via different methods, such as making use of the geometry asymmetry, mechanical stress field, defect engineering, inhomogeneous electric field, and a sweeping biased tip. Facile manipulation of the toroidal order in ferroelectrics remains challenging. Here, we propose an efficient scheme for controlling the chirality of ferroelectric toroidal order. A trilinear coupling relationship between polarization, toroidization and the twist force is derived, based on which, two feasible strategies of controlling ferroelectric toroidal order by a combination of homogeneous electric field and torque are suggested and further carried out for ferroelectric toroidal order, polar-toroidal multi-order (PTMO) state, and ferroelectric skyrmion in ferroelectric nanodots and nanowires using first-principles-based effective Hamiltonian simulations and phase-field simulations. Our study demostrares facile control of toroidal order, PTMO state, and ferroelectric skyrmion, providing a good demonstrating of using shear strain engineering to control ferroelectric domain patterns and sheding light on the practical designing ferroelectric devices based on toroidal orders.

Benhour received his M.S. degree in mechanical engineering from Isfahan University of Technology, Iran in 2013. After that, Benhour joined the group of Dr. Hogan at the University of Alberta in January 2018. He is currently investigating the microstructural behavior of novel cermet materials.


In the present study, a microstructure-based finite element model for a two phase titanium aluminide alumina cermet is proposed based on a modified Gurson model. A face-centered cubic unit cell structure is used to obtain the high particle volume fraction. Then, an experimental quasi-static compression test together with a novel digital image correlation technique is performed to validate the modelling results. Once validated, the effect of varying the mechanical properties and microstructure parameters on material response and deformation evolution are explored. In addition, some of the unique mechanical properties of this material such as strain hardening parameters are found for the first time. Moreover, according to the size of the pores and inclusions, the interface effect for inclusion-inclusion, inclusion-matrix, void-inclusion, and void-matrix are also considered. The results for both stress-strain curve and the deformation evolution shows a good agreement with experimental data and can serve as a foundation for future microstructure optimization.

Munkhbayar Baatarsukh is a master student in Energy and Mechanical Engineering at the Gyeongsang National University of South Korea and was graduated his bachelor degree in petroleum chemicals of the National University of Mongolia. His research focus is related to Ni-free Ti-based Shape memory alloy and passion in remove hypersensitivity nickel element from biomaterials or replaces them with non-toxic biocompatible elements


Statement of the Problem: Shape memory alloys are commonly used for various application, e.g. aerospace, automotive, robotics and biomedical. Ti-Ni alloys have been extensively applied for biomedical uses to date, but it has been pointed out that pure Ni is a toxic element and causes Ni-hypersensitivity. The β-type titanium alloys attracted to attention for biomedical because of their low stiffness, good corrosion resistance, and biocompatible. The purpose of this study is to investigate the addition of Zr elements dependence on phase stability and mechanical properties of the β Ti-Nb-Zr thin films

Methodology & Theoretical Orientation: The Ti-Nb-(3.6-12.7)Zr at.% thin films were prepared by magnetron sputtering method. The structures of the thin films were analyzed by EDS and SEM. Phase constitutions were confirmed by XRD. Mechanical properties of the Ti-Nb-Zr thin film specimens were investigated by nanoindentation test. The d-electrons alloy theory is an effective method of designing titanium alloys with a controlled Young’s modulus.

Findings: The additional Zr content does not change crystallographic in the ternary alloy, α and β phases appear at alloys. The porous structures were observed in Ti-Nb-3.6Zr and Ti-Nb-5.6Zr thin films. Young’s modulus decreased from 94.65 GPa to 79.78 Gpa in ternary alloy with additional Zr content.Conclusion & Significance: The addition of the Zr to stabilize both α and β phases in titanium alloys, does not considerably influence the formation of α phases in TiNbZr alloy. In bulk, in order to control porous structure, there is used to space holder (NH4CO3) in sintering method. In the present, we expected to porous structure dependent on composition. The result of Young’s modulus confirmed to d-electro alloy theory for ternary alloy. However, Young’s modulus of ternary thin films (80-95 Gpa) lower than binary alloys (108-123GPa)

Bulk V2O5 is a diamagnetic semiconductor with a band gap (Eg) of about 2.3 eV, which is based on the ionic configuration with filled O2p and unoccupied V3d orbitals. However, the special electronic structure of V2O5 forms three bands, including V3d states, V3d split-off states, and mid-gap states, which lead to interesting optical properties of V2O5 micro-nanostructures. Therefore, the band edge absorption and photoluminescence (PL) peak positions of low-dimensional V2O5 material are not coincident. In this study, the fabrication processes, structure, optical characterization, and photocatalytic activity of V2O5 micro-nanostructures, including thin films, nanoparticles, micro-nanorods, micro-nanowires, nanospheres, nanohollows (NHs), and V2O5/RGO nanocomposites were summarized and analyzed. The wide ranges of band edge absorption and broad PL of V2O5 micro-nanostructures are clarified in terms of factors such as the morphology, synthesis method, growth conditions, micro-nano size, and phase transition. The relations among the separation, diffusion, recombination, and degradation of the electron-hole pairs in V2O5 micro-nanostructures are also discussed. The formation of α-V2O5 films occurred when the sample was annealed at temperatures below 500 ℃. As the annealing temperature increases, some of the α-V2O5 structures were distorted and restructured to form a high-quality mixture of α-β phase V2O5. This leads to wide absorption and enhancement of the visible-light. A larger number of V4+ oxidation states of V2O5 nanospheres strongly enhanced PL intensity compared with other structures that showed weak PL. In particular, V2O5 nanospheres showed intense ultraviolet (UV) PL near 395 nm (3.14 eV) due to strong excitation by UV light, while this PL peak was not observed from other nanostructures. A large amount of charge separation in V2O5 nanospheres and the large surface contact area in V2O5 nanohollows and nanoparticles result in more efficient photocatalytic activity than from V2O5 micro-nanorods and micro-nanowires.

With respect to the perspective engineering applications of nanostructured (NS) metallic materials, apart from the strength and ductility under monotonic loading, their cyclic deformation response is another essentially crucial concern owning to safety issues. Compared with their CG references, NS materials generally exhibit enhanced high-cycle fatigue (HCF) and decreased low-cycle fatigue (LCF) properties in the light of the dependence of fatigue lives on the stress and strain amplitudes, respectively. Our recent investigations revealed that prominent improvement of the LCF lives and HCF strengths, especially fatigue endurance limits, of NS metals and alloys, can be simultaneously achieved with decreasing their stacking fault energy (SFE). These upgraded fatigue performances with lowering the SFE in NS materials can be attributed not only to the simultaneous increase of their monotonic strength and ductility in macroscale, but also to the crucially decreased cyclic softening behavior in terms of grain coarsening and shear banding in microscale. In addition, the dominant fatigue damage micro-mechanism was also transformed inherently from extensive grain boundary (GB) migration to other local GB activities such as atom shuffling or GB sliding/rotation with the reduction of the SFE. Owing to the limitation of their intrinsic fatigue mechanisms, the fatigue endurance limits of NS metals and alloys cannot always acquire appreciable improvement with their monotonic strengths. However, tuning the microstructures to harvest a recrystallized nanostructure can significantly enhance the fatigue strength of NS materials despite the lower tensile strength. These results enable us to timely exploit the knowledge of fatigue behavior of NS metallic materials, which is important both scientifically, for the in-depth comprehension of their deformation behavior, and technologically, for assessing their service utilities in safety-critical structural components, and also open up promising venues for materials design to possess optimal mechanical properties.

Abstract (300 word limit)

Time is a very poorly understood entity in physics. Newtons laws of motion or the equations of special relativity are invariant under time reversal. Yet in the classical world time always increases in the forward direction. One can only understand this at a statistical level using the concept of entropy but a microscopic understanding in terms of the equations of motion is absent. One may thus resort to Quantum Mechanics for an answer as one may expect classicality to emerge from that. Time irreversibility does have a role to play in the standard model.  However, there is no self adjoint time operator defined in quantum mechanics with time playing the role of a parameter in the time reversible Schrodinger Eq. In quantum mechanics time intervals can be defined in several ways and can also be probed experimentally. Different definitions correspond to different situations besides in Quantum Mechanics what is measured always depends on the way it is measured. Our interest is traversal time and signal propagation time which are the quantum analogue of a classical time interval. The talk will provide a clear view of the interpretation of the two times. According to Copenhagen interpretation of Quantum Mechanics the two should be the same but the issue is not settled yet in regimes where they can be negative. We use Argand-diagram and Burgers-circuit to show that the correct traversal time and the correct signal propagation time can be identically negative implying signal can be propagated in negative time. We will show that nano-scale semiconductor or metallic systems can become an excellent testing ground to reveal propagation in backward time and can give us a very neat understanding on the nature of time.

Abstract (300 word limit)

Two dimensional (2D) van der Waals (vdW) materials, consisting of atomically thin layers, have fascinating physical properties and intriguing thickness-dependent characteristics. To date, research on these materials has predominantly focused on various devices based on their optical and electronic properties, whilst reports on magnetic and spintronic devices based on 2D vdW materials are scarce, because vdW materials with desirable magnetic properties have yet to be found. By performing anomalous Hall-effect transport measurements, we reveal that the magnetic properties of single crystalline vdW Fe3GeTe2 vary dramatically with thickness. Importantly, a single hard magnetic phase with a near square-shaped magnetic loop, large coercivity (up to 550 mT at 2 K) and strong perpendicular magnetic anisotropy were all observed in Fe3GeTe2 nanoflakes. These merits make Fe3GeTe2 the first vdW ferromagnetic material suitable for fabricating vdW magnetic heterostructures. Based on this material, various spintronic devices has been designed and fabricated.

Abstract (300 word limit)

In my talk, I will present recent progress from my lab in generating advanced biomedical technologies such as antibacterial surfaces, drug delivery platforms, cell guidance surfaces and cancer diagnostics. One problem that we intensively tackle is the undesired bacterial adhesion to medical device surfaces, which is a significant medical problem. We have created four classes of antibacterial surfaces, based on their mode of action, settable for application on a range of medical devices. Important for applications, we not only extensively test our coating for their antibacterial efficacy against medically relevant pathogens and isolates but also evaluate their potential cytotoxicity to mammalian cell and tissue, and potential inflammatory consequences. I will also outline our work on developing advanced nanoengineered plasma polymer coatings capable of directing cellular behavior including adhesion, proliferation, differentiation and migration. Using our technologies, we are capable of controlling and tailoring the entire spectrum of surface properties including chemistry, wettability, ligand densities, nanomechanics and nanotopography in a substrate independent fashion. I will demonstrate how we use surface gradients of nanoparticles density to study the influence of surface nanotopography on the behavior of various cell types, including immune cells. We are also capable of guiding the differentiation of stem cells by tailoring surface chemistry, nanotopography or density of signaling molecules. A recently developed device for selective cancer cell capture for complex liquids will also be presented.
