KU–KBSI-UNIST research team develops high-performance electrode catalysts for water-splitting Results published in leading journal Advanced Materials ▲ Dr. Aram Oh, Ho Young Kim, Dr. Hionsuck Baik, Prof. Sang Hoon Joo, Prof. Kwangyeol Lee (from left) Water electrolysis technology, which breaks down water to obtain hydrogen, is recognized as a clean technology that does not produce carbon dioxide or other pollutants. In particular, water electrolysis in acidic media has come under the spotlight for its high activity. However, the high cost and low durability of the iridium or ruthenium catalysts are obstacles to commercialization, but have been overcome thanks to a new electrode catalyst developed by a local research team. The team, comprised of members of Korea University (Prof. Kwangyeol Lee, Department of Chemistry), the Korea Basic Science Institute (Aram Oh and Hionsuck Baik), and the Ulsan National Institute of Science and Technology (Prof. Sang Hoon Joo and Ho Young Kim), fabricated a Pt/Ni/Ru nanocrystal, and utilized it as an electrode catalyst for water electrolysis in acidic media. With this proposed nanocrystal electrode catalyst, they succeeded in achieving the world best standard of activity and durability for water-splitting electrode catalysts. The team fabricated a core double-shell icosahedral Pt/Ni/Ru nanocrystal by applying phase dissociation to a nanoparticle alloy comprised of multiple elements, and examined the structure and composition of the nanoparticles through double modified aberration-corrected transmission electron microscopy. After acid and heat treatment, they produced a new type of nanocrystal, consisting of a Ni/Ru-doped Pt core and a Pt/Ni-doped RuO2 frame shell. The proposed nanocatalyst featured catalytic activity 15 times higher than current commercial iridium catalysts. While commercial iridium catalysts only managed to retain 40% of their initial performance after 10 hours of operation, the proposed catalyst retained 90%, demonstrating its durability. The core and frame shell structure of the proposed catalysts minimizes the use of expensive metal, and has optimal area for high catalytic activity. Through the synergistic Pt/Ni/Ru relationship, the team achieved the world’s highest activity and durability for water electrolysis reactions. They were also able to examine the mechanism behind the formation of frame-type nanoparticles using the high spatial resolution (60 pm) transmission electron microscope owned by the Seoul center of KBSI. Professor Kwangyeol Lee said, “To commercialize this technology, we are conducting follow-up studies on the mass production of catalysts, and the extension of stable operation time. The catalytic activity and improved durability of unstable metal oxides doped with other elements can be applied to various catalytic systems related to energy and the environment, and thereby play a part in overcoming environmental issues.” Professor Sang Hoon Joo of UNIST said, “Further research will be conducted to study the principles behind the improved catalytic activity and durability of the new catalyst.” Supported by the National Research Foundation of Korea and KBSI, the study was published in the online version of Advanced Materials, a leading journal in nanoscience, chemistry and materials science, on October 26 under the title of “Topotactic Transformations in an Icosahedral Nanocrystal to Form Efficient Water‐Splitting Catalysts.” [Fig. 1] TEM image of the high-performance Pt/Ni/Ru nanocatalyst, and a schematic evaluating the performance of the electrode catalyst for water electrolysis [Fig. 2] Schematic of water electrolysis
International Academic Conference in Celebration of 30th Anniversary of Constitutional Court The Korea University School of Law held 2018 Korea-Germany International Conference In celebrating the 30th Anniversary of the establishment of the Korean Constitutional Court, the Korea University School of Law held the 2018 Korea-Germany International Conference on campus on Tuesday and Wednesday, November 6-7, in association with the Konrad Adenauer Foundation and the Constitutional Academic and Professional Association. At the Conference, participants discussed how faithfully the Constitutional Court is playing its role as a protector of the Constitution at the interstices of law and politics, and how the administration of justice should be reformed to ensure the independence of the judiciary. On November 6, the first discussion – titled “Judicial Assessments of Constitutionality and Democracy: Is the Constitutional Court a protector of the Constitution or a political player?”, and presided over by Professor Seung-ju Bang from Hanyang University Law School – started at 2p.m, with the opening speeches by Dean of the Korea University School of Law Soon-gu Myung and Director of the Korean office of the Konrad Adenauer Foundation Stefan Samse. Former Deputy Chief Justice of the German Federal Administrative Supreme Court and Former Deputy Chief Justice of the Berlin State Constitutional Court Michael Hund, currently an attorney at law, delivered the first presentation, titled “Judicial Assessments of Constitutionality and of Administrative Law in a Democracy: How Political is German Jurisprudence?” Comparing aspects of the Korean and German Constitutional Courts, Hund provided 12 theses which addressed two questions, namely the status under the German Constitution of trials held in the Constitutional and Administrative courts, and the extent to which these courts are political. The next speaker was Professor Seon-Taek Kim from the KU School of Law. In his presentation on “The Constitution and Judicial Assessments of Constitutionality: on the Border of Law and Politics,” he began by emphasizing the duality of the Constitution and the Constitutional Court due to the opposing pulls of the ideals of justice and of political philosophy and practicality. Touching upon historical cases of the tension between law and politics in the Korean judiciary's assessments of the constitutionality of certain actions or laws, he talked about the distinctive status, mission and structure of the Constitutional Court, and the limits on the adherence to the Constitution on the part of the judiciary itself. A follow-up discussion began at 4 p.m. after a short break. Professor Tae-ho Chung from Kyung Hee University Law School, Professor Sang Hie Han from Konkuk University Law School, Constitution Researcher at the Constitutional Court Ji-Hyun Kim, Professor Jung-in Yoon from the Korea University Legal Research Institute, Public Relations Officer at the Berlin Criminal Court Justice Lisa Jani, and Constitution Researcher at the German Federal Constitutional Court Dr. Philipp Wittmann shared their thoughts on the presentation. Justice Jani and Dr. Wittmann also elaborated on the ways in which the German Federal Constitutional Court has protected the nation’s democracy and the Constitution through its proceedings. Finally, there was an hour-long open Q&A session and wrap-up discussion from 5 to 6 p.m. before the Day 1 proceedings were concluded. On November 7, six Korean participants (including Professor Seung-ju Bang) and two German counterparts engaged in a round-table discussion on “The Independence of Judges and the Judicial Administration.” The Korean speakers addressed the current issue of the Supreme Court corruption scandal, in which a former justice is suspected of having been bribed to intentionally delay a trial and to press other judges to do the same, the potential, or – as many believe – likely, result of which might have generated unfavorable public opinion about the then government. The speakers also discussed the possible actions that should be taken to address valid concerns about the scandal. Dr. Wittman talked about the Distortion of Law Act, which stipulates that judges who commit crimes while in office and thereby fail to uphold justice be punished, as well as how the above-mentioned Korean judicial scandal is viewed in Germany. All participants at the conference shared fruitful ideas about how judges in Korea can secure their independence from external pressures, with reference to the case of Germany. “Korea is going through a challenging time due to its failures to meet the standards of a democracy operating under the rule of law,” Lawyer Jae-Young Kim said. “The kinds of thoroughgoing judicial reform discussed at this conference will hopefully help the nation overcome these problems.”

Korea University hosts 2018 Career Odyssey Festival The largest on-campus job fair in Korea, attended by over 170 companies from home and abroad, took place between September 4 and 6. Korea University hosted the 2018 Career Odyssey Festival in the Hwajeong Tiger Dome from September 4 through September 6, at 10:00-17:00. The three-day festival, the largest on-campus job fair in Korea, invited all the major Korean companies to attend, including Samsung, LG, Hyundai Motors, SK, GS, KT, CJ, LS, Lotte, POSCO, Hyosung, Dongwon, and Hanhwa, which plan to recruit university graduates and prospective graduates in the second half of this year. These firms offered on-the-spot job consulting services to potential future employees. The booths of the Ministry of Employment and Labor (Northern Branch of the Seoul District Employment and Labor Office), the state-owned company Korea Power Exchange, and foreign companies such as Bloomberg and Continental Automotive were present, and Japanese HR businesses such as PERSOL Korea, Manavi Korea and Connect Job also contributed to the fair. The event was packed with KU students from day one. Participants formed a line in front of the booths of several renowned firms to gain personal job consultations on recruitment criteria, appraisal criteria, and company culture. “The queuing was worthwhile as I learned a lot of non-public information from company employees on the benefits and annual salary the firm, and the potential work assignments there,” said Jun-ho Eum, aged 23, from the Department of Electrical Engineering, after lining up in front of the booth of LG Electronics. “I've acquired an understanding of the precise expectations that many firms here have of their prospective employees. This information will be quite helpful for me to better understand what I have to do in terms of developing my personal statement,” said Min-jun Park, aged 25, from the Department of Economics. The event was attended by not only graduating students and graduates but also current students, who came between classes. “As I have just started working on job applications, I need help in many ways. So I’m here and I learned of a lot of in-house information from employees in many firms,” said Il-hwan Kim, aged 24, from the Department of Electrical Engineering (entry class 2014). “I gave up my lunchbreak to be here, and it's been worth it,” he added. A HR manager who was offering in situ job consulting services to students said, “Not only graduates but also graduating students can get professional help through responses to their questions about preparing for jobs. As we also provide various free gifts in addition to consulting services, there's a lot in it even for more junior students if they decide to attend the fair.” The festival also established several booths to offer students mock job interviews and on-the-spot proofreading of their personal statements. “The proofreader advised me that my account of my military service in my personal statement sounds too ordinary or obvious and the instance of conflict management I relate is unimpressive. Now I have a better idea of how to develop my personal statement,” said Seok-ho Lee, aged 25, from the Department of Korean Language and Literature. Participants were able to register for the 2018 Career Odyssey Festival in advance on its website (www.2018kujobfair.com) or on the spot. Korea University arranged additional shuttle buses from Anam Subway Station Exit 2 and Korea University Subway Station Exit 1 to the Hwajeong Tiger Dome during the event to ensure easy access for students to the venue.
