President Doh-Yeon Kim Signs the First Multilateral MOU of K-STAR

20181015 MOUOn behalf of K-STAR (Korean Universities for Science & Technology and Advanced Research), President Doh-Yeon Kim signed into effect the first multilateral MOU of the cooperative initiative with the INSA Group (Institut National des Sciences Appliquées) of France.

President Kim, representing K-STAR, attended the signing ceremony held on the 15th in Paris alongside M’Hamed Drissi, Directeur de l’INSA Rennes. As part of South Korean President Moon Jae-in’s visit to France, the respective Ministers from both countries (Korea’s Ministry of Science and ICT and France’s Ministry of Higher Education, Research and Innovation) also attended the ceremony.

As the alliance of leading STEM universities in Korea, K-STAR is comprised of KAIST, DGIST, GIST, UNIST, and POSTECH. The INSA Group is the leading French group of grande écoles and is comprised of 6 INSA institutes: Centre Val de Loire, Lyon, Rennes, Rouen, Strasbourg, and Toulouse. The collaborative activities between the two national networks will include academic and student exchanges to foster international cooperation between and Korea and France.

The multilateral agreement between K-STAR and INSA Group is expected to usher in a new vibrant era of robust partnership in science and technology for both nations.

Shedding Light on the Understanding of High Entropy Alloys

From the cargo ships and airplanes traversing the globe to the automobiles and buildings sprawled throughout the landscape, much of the modern world is built with and upon alloys such as steel. Metallurgists throughout history have passionately struggled to develop novel alloys that are both strong and ductile—properties often diametrically opposed but collectively desired. According to collaborative research conducted by POSTECH and KTH – Royal Institute of Technology, the development of an alloy that surpasses the existing limitation of strength and ductility may soon be possible.

 

Traditional alloys are usually composed of a main metal, such as iron, and small percentages of different elements, such as carbon. A small percentage of carbon (under 2%) combined with iron produces steel, which is a thousand-fold stronger than pure iron. In contrast to the base element paradigm, high-entropy alloys (HEAs) are new substances that are fabricated with equal or nearly equal quantities of multiple metals, and as such, may have highly desirable properties not found in nature. For example, a popular HEA among researchers is the CoCrFeMnNi, which has been found to have extremely high fracture toughness where both ductility and yield strength increase as the temperature decreases. However, many HEAs with such alluring properties are not thermodynamically stable under normal conditions, and consequently, further in-depth research has been limited.

 

Professor Se Kyun Kwon from the Graduate Institute of Ferrous Technology at POSTECH and Professor Levente Vitos from KTH used first-principle quantum mechanical tools to demonstrate that a deformation mechanism known as twinning could be precisely controlled to design HEAs with qualities that shatter current limitations. This achievement was published in the world-renowned journal Nature Communications.

 

Twinning is one of the fundamental modes by which metals and alloys can deform plastically. At the atomic level, alloys are made up of a grid-like structure. Under the appropriate amount of stress, the alloy will deform according to one of the deformation mechanisms. The research team’s theory demonstrated that the control of the specific mechanism is feasible, by which researchers will be able to “facilitate the optical harvesting of their properties.”

 

Professor Kwon expressed his excitement in applying this new understanding of the plasticity of HEAs to further research on not only designing but developing novel alloys with superb properties for usage in extreme and harsh conditions.

 

This work was supported in part by the Swedish Research Council, the Swedish Foundation for Strategic Research, and the National Research Foundation of Korea.

Professor Kimoon Kim Publishes the First Textbook on Cucurbiturils

Professor Kimoon Kim (Director, Center for Self-assembly and Complexity, IBS) has published the first textbook on cucurbiturils entitled Cucurbiturils: Chemistry, Supramolecular Chemistry and Applications through the world-renowned World Scientific.

 

Once considered a peculiarity, cucurbiturils—molecules shaped like a hollow pumpkin—has since been propelled to the forefront of supramolecular chemistry due to their suitability as hosts for an array of neutral and cationic species. For years, Professor Kim, a prominent leader and internationally recognized authority in the field of supramolecular chemistry, has been working on a wide variety of functional materials based on cucurbiturils. In his career, he has published over 260 papers that have amassed over 22,600 citations. Most notably, his paper published in Nature in 2000 was selected as one of the 35 most notable papers among chemical related papers published in Nature from 1950 to 2000.

CB-Book-표지[1]

The textbook chronicles the history and development of cucurbiturils and provides a general introduction and a field-wide overview of the synthesis, properties and applications of the fascinating macrocyclic molecules. Comprised of nine chapters that detail among other topics, preparation, properties and host-guest chemistry, the textbook showcases the uses of cucurbiturils in chemistry, materials science and biology.

 

Professor Kim expressed his enthusiasm on the publication and commented that the textbook is “an essential resource for both new and experienced researchers, as it provides an overview of the diverse applications, new methodologies and research, as well as challenges in the field.”

 

The publication is made even more noteworthy because Professor Kim will donate his entire royalty to POSTECH to nurture the next generation of scientists.

Application Open: World Culture Awareness Programme

World Culture Awareness Programme

 

The World Culture Awareness Programme (WCAP) is organized by Gyeongsangbuk-do Office of Education in cooperation with POSTECH. This program provides POSTECH international members with the opportunity to introduce their home countries’ cultures to Korean students at local elementary, and middle schools. Participants will be paired with Korean translators who will be selected by POSTECH International Relations. Participants and translators will visit local schools together as a team, and introduce Korean students their home country’s culture, traditions, and history. This program will ultimately enhance students’ understanding and respect the cultures of other countries.

 

  • Compensation
  • Compensation for participants will vary depending on the distance of the assigned school as below.

Name of schools

Compensation

Yonghung Elementary School, Jigok Elementary School, Leedong Middle School

KRW 40,000 per participant
