KAIST Develops Core Technology to Synthesize a Helical Nanostructure
Professor Dong-Ki Yoon’s research team of the Graduate School of Nanoscience and Technology (GSNT) at KAIST has developed helical nanostructures using self-assembly processes. The results were published in the Proceedings of the National Academy of Sciences of the United States of America(PNAS) on the October 7th.
This technology enables the synthesis of various helical structures on a relatively large confined area. Its synthesis is often considered the most arduous for three dimensional structures. Formed from liquid crystal, the structure holds a regular helical structure within the confined space of 20 to 300 nanometers. Also, the distance between each pattern increased as the diameter of the nanostructure increased.
Liquid crystals have a unique property of responding sensitively to the surrounding electromagnetic field. The technology, in combination with the electromagnetic property of liquid crystal, is expected to foster the development of highly efficient optoelectronic devices.
Using this technology, it is possible to develop three dimensional patterning technology beyond the current semiconductor manufacturing technology which uses two dimensional photolithography processes. Three-dimensional semiconductor devices are expected to store hundred times more data than current devices. They will also lower costs by simplifying manufacturing processes.
The essence of this research, “self-assembly in confined space,” refers to controlling complex nanostructures, which can be synthesized from materials such as macromolecules, liquid crystal molecules, and biomolecules in relation to surrounding environments including the temperature, concentration, and pH.
The research team produced a confined space with a length of tens of nanometers by using a porous anodized aluminum membrane induced from an electrochemical reaction. They successfully synthesized independently controlled helical nanostructures by forming the helical structures from liquid crystal molecules within that space.
Professor Yoon said, “This research examines the physicochemical principle of controlling helical nanostructures.” He highlighted the significance of the research and commented, “The technology enables the control of complex nanostructures from organic molecules by using confined space and surface reforming.”
He added that, “When grafted with nanotechnology or information technology, this technology will spur new growth to liquid crystal-related industries such as the LCD.”
The research was led by two Ph.D. candidates, Hanim Kim and Sunhee Lee, under the guidance of Professor Yoon. Dr. Tae-Joo Shin of the Pohang Accelerator Laboratory, Professor Sang-Bok Lee of the University of Maryland, and Professor Noel Clark of the University of Colorado also participated.

The 2014 SoC Robot Competition Took Place
Professor Hoi-Jun Yoo of the Department of Electrical Engineering at KAIST and his research team hosted a competition for miniature robots with artificial intelligence at KINTEX in Ilsan, Korea, on October 23-26, 2014.
The competition, called the 2014 SoC Robot War, showed the latest developments of semiconductor and robot technology through the robots’ presentations of the Korean martial art, Taekwondo, and hurdles race. SoC is a system on ship, an integrated circuit that holds all components of a computer or other electronic systems in a single chip. SoC robots are equipped with an artificial intelligence system, and therefore, can recognize things on their own or respond automatically to environmental changes. SoC robots are developed with the integration of semiconductor technology and robotics engineering.
Marking the thirteenth competition this year since its inception, the Robot War featured two competitions between HURO and Taekwon Robots. Under the HURO competition, participating robots were required to run a hurdle race, pass through barricades, and cross a bridge. The winning team received an award from the president of the Republic of Korea. Robots participating in the Taekwon Robot competition performed some of the main movements of Taekwondo such as front and side kicks and fist techniques. The winning team received an award from the prime minster of the Republic of Korea.
A total of 105 teams with 530 students and researchers from different universities across the country participated in preliminaries, and 30 teams qualified for the final competition.

KAIST and Samsung Heavy Industries Celebrate 20 Years of Cooperation
KAIST and Samsung Heavy Industries (SHI) celebrated the twentieth anniversary of their university-industry cooperation in shipbuilding and ocean technology research. Established in 1995, the cooperation has remained steadfast for two decades, even times when Korea suffered gravely from its financial crisis in late 1990s.
A ceremony to commemorate the cooperation took place at the Mechanical Engineering Building on October 17, 2014. About thirty distinguished guests including the Head of the Department of Mechanical Engineering, Professor Choong-Sik Bae, and the chief engineer of SHI Marine Research Institute, Dr. Jong-Soo Seo, participated in the ceremony.
The cooperation programs included appointing advisory professors for technological support, implementing business-based academic courses, offering university-industry wide open lectures, opening regular courses for auditing, and finding possible joint researches. Through this cooperation, Samsung has secured technologies needed for industry, and KAIST has produced students who have real-world experience in industrial fields.
Twenty years of cooperation has produced shining results by running various programs such as technological advice, special lectures, small-scale research projects, consignment research projects, and courses for research and design personnel.
For example, what started as a small-scale research project with USD 4,800 in funding, the LNG (Liquefied Natural Gas) related research has grown into a large-scale research project with a total of USD 2.85 million in funding. As a result, they developed a secondary barrier for LNG carriers which was recognized by Lloyd‘s Register. Their research eventually lowered ship manufacturing costs tremendously.
In 2003, the cooperation project received the presidential citation from the University-Industry Cooperation Competition organized by the Federation of Korean Industries.
KAIST and SHI planned to increase their cooperation to make it Korea’s leading university-industry cooperation program.
Professor Bae said, “Our programs to focus on solving industrial problems have turned out quite successful.” He emphasized that “for this reason, the cooperation even continued during the Asian financial crisis in 1997.”
He added, “By expanding the current cooperation, we aim to make it an exemplary program that contributes to Korea’s shipbuilding and ocean plant industries.”
