Prof. Seonkuk Kim's Team Develops System to Monitor the Durability of Phototransmittance Based Structures

Professor Seonkuk KIM's research team (lead author: Hyelin LIM/co-author: Seongin HONG) announced that they have published an article in "Advanced Materials" about their research on developing a system to monitor the durability of phototransmittance based structures.

Prof. Kim's team cooperated with Prof. Hanseung LEE's team from Hanyang University to design a monitoring system by quantifying deterioration factors inside concrete. The research team developed a new type of multifunctional monitoring technology by using a unique structure that arrays IGZO phototransistors into layers.

Prof. Kim said, "We are anticipating that this research will overcome the limitations of the previous monitoring system." Prof. Kim is conducting research on two-dimensional materials and post-generation nano-bio electronic devices.

This research was conducted under the sponsorship of the National Research Foundation of Korea.

Prof. Gayoung Jung Reveals Signal Transduction Process of Medicine Receptors

Prof. Gayoung JUNG's research team (SKKU, Dept of Pharmacy) announced in the world renowned journal "CELL" that it revealed the process of sequential structural transformation in a cell that leads to the combination of G Protein and its receptor. This discovery has created the opportunity to develop a new drug.

G Protein receptors activate signal transduction by combining internal G Protein when they sense external signals. Simply speaking, they act like buttons that control the functions of the human body. This research is anticipated to enable development/improvement of new drugs considering the fact that over 40% of medicines work this way.

The 2012 Nobel Prize in Chemistry went to Professor Robert Lefkowitz (Duke University) and Brian Kobilka (Stanford University) for discovering the structure of G Protein-coupled receptors. They were able to prove that G Protein is relevant to many diseases, but failed to prove the principle of its action.

Prof. Jung's research has taken the Nobel Prize winning research a step further. Prof. Jung has proven that the G Protein receptor structure found earlier is not a suitable model for the development of new drugs and suggested that the G Protein receptor structure in the early stage of combination is more suitable for that purpose.

Prof. Jung said, "We have proposed a theory that changes the paradigm of G Protein activation. It will be a new strategy in developing G Protein activating medicine."

Prof. Munseok Jeong's Research Team Develops Chameleon-like Semiconductor Nanodevice

Professor Munseok JEONG and researcher Ngoc Thanh DUONG (doctorate course) have developed a new device through joint research with Prof. Sungjoo LIM. The newly developed device is able to output a different notation system (binary, ternary, and quinary at maximum) depending on the existence of light. It was posted in the world renowned journal ACS Nano's (IF=13.709) April 23rd issue.

A normal integrated circuit operates by storing either 1 or 0 as a "bit". This is because the output of a device is recognized by two types: on and off. If an output larger than ternary notation can be realized in a device, it can extensively improve the performance of an integrated circuit.

The minimal unit of computer data processing "byte" uses 8 "bit" as the standard unit. Setting 1 byte as a standard, 6,561 outputs can be produced using ternary notation. This is 25 times greater than binary notation, which produces 256 outputs. Also, if it is possible to realize quinary notation, the performance will improve 1,000 times with just a single byte.

The research team used two-dimensional materials such as Molybdenum ditelluride (MoTe2) and Molybdenum disulfide (MoS2) compound to create a Van der Waals heterojunction device. They were able to develop a multi-level electronic device by using the negative differential transconductance phenomenon discovered from the heterojunction device.

Prof. Jeong said, "This research is expected overcome the difficulties in the 4th Industrial Revolution such as high power consumption due to big data and AI and data processing speed by improving the efficiency of electronic devices."

This research was conducted through the support of the Institute for Basic Science and the National Research Foundation of Korea.

Prof. Changwoo Lee’s Team Discovers DNA Recovery Control Function of Immune Related Protein

The National Research Foundation of Korea announced on April 16th that Prof. Changwoo LEE (SKKU) and Hyesung CHO's (Ajou University) research team discovered a control system that recognizes and repairs genes inside the human body.

When the DNA is damaged due to an internal issue, a system activates within the body to recognize and repair the gene. This is very important to control and suppress diseases such as cancer.

The 2015 Nobel Prize in Chemistry was awarded to three researchers who studied "mechanistic studies of DNA repair". That shows that this research topic is under the spotlight of the academic world.

The research team was able to prove the effect of the "Pellino 1" protein in accelerating the restoration of the DNA. Lee said, "With this discovery, we are now able to understand the cause of many illnesses (genetic disorders, immune disorders, cancer, metabolic disease, etc.) from a new perspective. This will be the foundation to develop medicines for these illnesses."

Prof. Changhyun Bang Receives the Scientist of the Month Award

Professor Changhyun BANG (Dept. of Chemical Engineering) was named the "Scientist of the Month" in April for developing a sucker-imitated high adhesive patch.

Prof Bang has proven that the sucker of an octopus increases absorptive power even in the water and applied this discovery to develop a new patch material that can stick in any environment. The sucker-imitated patch showed high adhesiveness in water, on the surface of glass inside silicon oil, soggy skin, and various other environments.

The "Scientist of the Month" award is co-managed by the Ministry of Science and ICT and the National Research Foundation of Korea. The awardees receive 10 million KRW as a reward.

Prof. Youngdok Kim’s Research Team Develops Fine-Dust Purifying Photocatalytic Concrete

On March 27th, Nature & Environment Inc.'s Research Institute announced that Prof. Youngdok KIM's research team successfully developed an "atmosphere purifying concrete block". Nature & Environment Inc. is currently promoting the installation of concrete blocks with local governments.

Prof. Kim's team developed a way to dissolve the volatile organic compound acetaldehyde into a visible light LED. When the new material is installed at a school field track (5000㎡), it dissolves about 50g of acetaldehyde per hour. Volatile organic compounds are carcinogens and are known to be one of sources of fine dust.
