Welcome to Materials Science and Engineering The School of Materials Science and Engineering(MSE) at UNIST pursues a path to become a leader in materials science and engineering field, on the basis of strong academic program, highly regarded faculty, and self-driven students. The mission of the MSE is to provide our graduates with high-level of education and research experience in order to prepare them to meet the expert needs of academia, industry and national labs when it comes to scientific and engineering issues related to materials science and engineering. The MSE aims to build up strong programs to strengthen the research and education for emerging advanced materials and imminent industrial innovation, and, thus, offers two academic tracks for in-depth educational instruction; Advanced Materials Science(AMS) and Nano Materials Engineering(NME). In an effort to make pioneering advances in materials research, the current research and interests within the MSE ranges from the pure, fundamental science of advanced materials to applied science and engineering, production and utilization of nano materials. Our goal is to address the emerging scientific and engineering

Introduction

Introduction The discovery of new materials and improvement of existing ones are crucial to bettering our quality of life and solving critical technological and societal problems. Making safe, fuel efficient vehicles requires light weight, strong materials. Improving the performance of jet engines requires new materials that can be used at high temperature. Increasing the computing capabilities of microprocessors requires improved materials for use in ever smaller integrated circuits. Developing new fuels and new sources of energy involve designing new materials for energy conversion and transmission. Integration of advanced capabilities in electronics with medicine or the environment requires the development of new materials systems with that exhibit high performance and stability in harsh environments. These challenges are among the many types that materials scientists and engineers take on in their daily routines.

The research is manly focused on polymer based optoelectronic devices using the nanomaterials and nanotechnology.
Two emerging keywords in ceramic community are sustainability and tailored functionality for advanced applications. This high-efficient-oriented and eco-friendly approach are to respond properly to the environmental regulations getting tougher and tougher. One of the biggest challenges on this quest lies in the fact that most useful ceramic materials contain nominally toxic elements that should be eventually removed. Our goal is to best-tailor the functionality of ceramic materials to meet the requirements for practical applications in accordance with the environmental appropriateness.

Super-Lightweight Materials Lab.
The focus of our research group is the intersection of the fields of organic/molecular electronics, spintronics, optoelectronics with exploiting metal-organic hybrid materials. Within this umbrella we are pursuing projects involving both developing new hybrid materials with desired magnetic and electronic properties, electrical and optical studies of spin scattering, spin transport, and magnetic interactions in nanoscale hybrid structures, films from molecular monolayers to multi-layers, and novel hybrid heterostructures.
Our work in “Super-Lightweight Materials Laboratory” has been mainly focused on the design, development and analysis of multi-component metallic alloys, which include lightweight Mg and Al alloys, bulk amorphous alloys with high specific strength, and lightweight steels with enhanced toughness. These studies are mostly supplemented with modeling and simulations to reveal atomistic mechanisms governing structure-property-performance relationships for our novel alloys under development.

Our primary research interests lie in investigating the local property of the nanomaterials. STM (scanning tunneling microscope) and SFM (scanning force microscope) are our main experimental tools, which offer suitable means for investigating local properties by direct real-space visualization at the atomic level. We would like to develop useful insights for basic questions regarding the nature of nanostructures and their interfaces, and ultimately pursue novel nanoscale devices and sensors having better performance.
We focus on development of multifunctional materials with innovative mechanical, electrical, and chemical performance by designing and controlling microstructures at the nano-scale. They have the applications in water splitting solar cell, flexible display materials, micro opto-mechanical devices. In addition, we focus on making the multifunctional materials and devices reliable and durable at harsh environments such as high/low temperature, chemical corrosion, and wear, which have the applications in nano electronic devices, aerospace plane, green transportation, and energy conversion systems.

We focus on the spin dynamics in patterned magnetic nanomaterials and its applications to spintronic devices. Our research aims at exploring the fundamental understandings of new concepts in spintronic devices by harnessing a “spin”, quantum states of an electron and its dynamics. Particular interests are concerned with the development of new information processing technology to break through the energy dissipation limit of current charge-based logic devices.
For many years, experiments and computer modeling have been significantly used for characterizing the microstructures of materials in order to study their relationship to desired properties and to optimize the materials design and performance. In fact, many problems related to the properties of materials are three-dimensional in nature because most practical materials have a polycrystalline or multi-phase structure with significant complexity in the spatial arrangement of the microstructural units. This is especially true for (metallic) structural/functional materials, since they are subject to various processes (for example, rolling). Therefore, it is of great interest to characterize microstructural parameters and reveal their effects on the properties of the materials in all three dimensions.

Jae Sung Son
Laboratory for Integrative Biomaterials Design and Tissue Engineering Our primary research interests lie in investigating the local property of the nanomaterials (single molecules, nanodots, nanotubes, nanowires, graphene, etc). In addition to the intrinsic properties of materials itself, we are much interested in the local variations of electronic properties arising from the external perturbations. STM (scanning tunneling microscope) and SFM (scanning force microscope) are our main experimental tools, which offer suitable means for investigating local properties by direct realspace visualization at the atomic level. We would like to develop useful insights for basic questions regarding the nature of nanostructures and their interfaces, and ultimately pursue novel nanoscale devices and sensors having better performance.

Exhilarated by Learning and Studying Bo Ram Lee (Graduate Student, Department of Materials Science and Engineering, Published in Nat. Comm., 2014) I chose to study engineering because I would like to develop practical applications based on basic science. I have been interested in light-emitting diode (LED) devices, and solar cell technology because of my interest in optical science. Synergy generated by the great relationship between professors and students, as well as collaboration between each lab, is enhancing the overall research capability. I was able to publish my research work in Nature Comm because of this synergy. Classroom theory and laboratory research organically combine without any barriers at the School of Materials Science and Engineering. The school provides the best environment for study and research.
