Zeolite is widely used as a petrochemical catalyst for the production of raw materials for petroleum and plastic products during crude oil refining. It is a core material whose nanostructure contains tiny holes arranged regularly and repeatedly, and is utilized as ion exchangers and separators. Specifically, these physical chemistry properties are primarily differed by the pole structure that the synthesis of zeolites can bring out the ripple effect in chemical related industries.Professor Hong Seok-bong (DESE) succeeded in synthesizing PST-14 and a new aluminophosphate molecular, PST-13. The

During an oil-spill catastrophe, it is important to separate oil and water accurately on a massive scale, as quickly as possible. A POSTECH research team recently developed a technology that separates a solution of water and oil continually, quickly, and accurately. This technology can effectively prevent the spread of marine oil pollution and enable safe disposure of industrial oil wastes.Jointly researched with a research team from Chungnam National University, Professor Lim Geun-bae (ME) and Hong Seong-kyung (ME, Ph.D. Integrated) created a hydrophilic oil-impermeable cellulose-based nanofi

Professor Park Moon-jeong (CHEM) and Kim Seung-jae (CHEM, Ph. D candidate) has developed a macromolecule actuator (artificial muscle) that can maintain its movement without electric power supply. It emulates the spontaneous flexure or volume change of plants’ roots or leaves when the surrounding environment changes. The research team used LEAP, a bilayer macromolecule that is activated by light and electricity to develop the actuator. This actuator’s strain has increased by 350%, and its strength increased three folds than the preexisting actuator. One key factor is that when the actuator sens

Park Jin-ho (PHYS, Ph.D. Candidate) in the laboratory of Professor Lee Hu-jong (PHYS) and Professor Lee Gil-ho (PHYS), succeeded in realizing the short ballistic Josephson coupling in planar graphene junctions for the first time, with Dr. Lee Jae-hyeong (Samsung Advanced Institute of Technology), Hiroshima University, Japan and Korea Institute of Materials Science. With this research, it became able to come to a step closer to realizing a stable quantum device requiring strong coherence. A superconductor is a material in which current flows under a certain temperature, called critical temperat

According to the Korea National Statistical Office, colorectal cancer ranked third in the leading cause of death in the nation’s mortality, an increase of 73% in just 15 years from 2001. The reason why the mortality rate is so high is due to the difficulty in detecting cancer in the early stages. Importantly, if found in the beginning, not only the survival rate, but also the progress of treatment is favorable.Through Professor Kim Sung-jee (CHEM) who has collaborated with Kim Ki-hean (ME), and Myung Seung-jae, developed a method to diagnose colorectal cancer using a fluorescent probe that res

El Nino, which means the water temperature increases near the equator, causes unexpected heavy rain and drought, due to the warming tide that can weaken the trade winds. Studies have shown that this phenomenon affects the carbon cycle that helps maintain the Earth’s ecosystem However, recently, it has been revealed that human-generated greenhouse gases have led to more interaction. In particular, it has been suggested that this amplified El Nino could significantly reduce the Amazon’s ability to absorb carbon.Professor Kug Jong-seong (SEE), Kim Jin-soo (SEE, Ph.D Candidate), and Jeong Su-jong,

Professor Kim Seung-hwan (PHYS), Kim Min-kyung (PHYS, Ph.D.), and a team from the University of Michigan Medical School found evidence of explosive synchronization in the brains of patients suffering from fibromyalgia. The research was published on the academic paper Scientific Report.Fibromyalgia is a type of a chronic pain disease, which affects about two percent of the whole population. Patients feel immense pain even with minute stimulations near areas such as shoulders or spine. Until now, the cause of the disease was unclear.The research team assumed to find the cause in the brain and me

A hyper lens developed by a domestic research team has achieved the living neuron observation for the first time. The research team by Professor Rho Jun-suk (ME) and Lee Da-sol (ME, Ph.D. Candidate) produced a 4-inch-scaled hyper lens. This led to the result that the team succeeded in observing the cell under the diffraction limit scale. This result was introduced in ACS Photonics. In an optical microscope, if the scale of the target is smaller than the wavelength of the light that the target reflects, which is called the diffraction limit, an observer cannot distinguish the target. Using a hy

Although smartphones’ functions are advancing every day, such as iris and facial scan, smart personal assistant using voice, the battery system does not seem to catch up. As an increase of battery consumption is proportional to functionality, the demand for a rapidly rechargeable battery is constantly growing. In the case of lithium ion batteries, as they are widely used in smartphones, laptops, and electric motored cars, the corresponding research is actively progressing.Professor Lee Jin-woo (CE) and Jo Chang-sin’s research team succeeded in simply synthesizing hierarchical porous inorganic

Professor Hahn Sei-kwang (MSE) and Keum Do-hee (MSE, Ph. D. Candidate) have developed a smart stent that can be used for diagnosis and therapy with the help of 3D printing technology. This was a joint research project with Professor Cho Dong-woo (ME) and Professor Kim Chul-hong (CiTE). A stent is a supporting fixture that is inserted inside blood vessels or organs to prevent them from being blocked. Surgical procedures using stents are well known, ranking fourth amongst most conducted surgeries in Korea. However, 90% of the products used are imported goods, thus local manufacturing is urgently

The Ministry of SMEs and Startups of Daegu and Gyeongbuk, who present these awards, receive applications from companies, and evaluate them using a judging committee composed of experts in the field.EyePia developed a field-of-view inspection system which

Liver cancer is the second highest cause of death amongst types of cancer. Progressive liver cancer only can be cured through the treatments for cancer. Professor Lee Yoon-tae (LIFE) and Kim Sang-uk (LIFE) and a graduate student Kim Eun-jeong (LIFE) verified that if Capicua (CIC), which is concerned with the progress of liver cancer, is decreased, cancer cell increases and escalates the speed of progression. The team of Prof. Kim verified that when ETV4 and MMP1, the subordinate control elements of CIC, are increased, the survival rate of patients decreases. Prof. Lee mentioned that “Not only

Professor Kim Dong-sung (ME) and Professor Kim Chul-hong (CiTE) team, developed a variable focus liquid lens and applied it to photoacoustic imagining devices to obtain high-quality biomedical images. Unlike fixed type solid lenses, liquid lenses have the flexibility to change the lens shape freely.The team developed a new concept liquid lens that can prevent the occurrence of electrolysis and adjust the focus freely and stably. The developed liquid lens adjusts the focus in two ways: vibration mode and static mode. This focus change is expected to be applied to scan image information from a t

When a tooth fails to function, due to a cavity, accident, or aging, an implant is considered as the final method. Although implants are widely executedtooth, it requires re-operation if the initial Osseo-integration is not completed within time. A POSTECH research team has exploited the constituents from mussels and a diatom to coat and manipulate the roughness of the surface of an implant and promote the implant to settle in quickly between ulitis.Professor Cha Hyung-joon (CE) and Doctor Jo Yoon-ki engaged in a collaborative research project with Professor Kim Chang-seop’s research team from

Professor Lim Geun-bae (ME), Jeon Hyung-kook (ME, Postdoc Associates), and Cho Seong-jin from ChungNam National University, have developed a metal layer nano structure that is inspired from a spider’s foot. The research team analyzed the movement of the joints, but also the structure of the spider’s foot to develop a system that can detect minute movements. They emulated foot structures to create nanoscale cracks, and used these structures to create sensors that detect deformation rate and elasticity. In particular, the study allows sensors to be used to measure large movements at joints, as w
