Challenging the conventional understanding that orbital angular momentum-based physical phenomena are diffi cult to occur in solids, Professor Lee proposed the possibility of developing a new magnetic memory device by utilizing orbital degrees of freedom.

Most substances exist in three states: solid, liquid, and gas. Going beyond this conventional understanding, Professor Kim successfully observed the fourth state, “nematic,” in quantum materials, which simultaneously exhibits the characteristics of both liquid and solid, marking the world's fi rst observation.

Professor Park has realized complex and unique block copolymer nanostructures that were previously only imagined by researchers through polymer end-group modifi cation. Notably, this work has attracted attention as the fi rst successful realization of the ‘plumber’s nightmare’ structure, where all the polymer chains converge at the center.

Collaborating with the Korea Research Institute of Standards and Science and the Pohang Accelerator Laboratory, Professor Noh’s research team developed a Tellurium-Selenium composite oxide semiconductor material and successfully demonstrated a high-performance, high-stability p-type thin-fi lm transistor (TFT). This research is expected to make a signifi cant contribution to next-generation display and low-power memory technologies.

In collaboration with North Carolina State University, Professor Jeong developed a process to print the natural oxide fi lm of liquid metals on a large scale continuously. This breakthrough enabled the successful fabrication of foldable transparent electrodes and circuits with nanometer-thick layers that are resistant to scratches.

Through collaborative research with teams from Georgia Tech and Northwestern University, Professor Kim developed a wireless haptic device that adheres to the skin. This device alternates stably between pressure and expansion states, selfdetects deformation, and offers excellent energy effi ciency and signifi cantly improves the accuracy of sensory stimuli.

Professor Keehoon Kim’s research team integrated the body part connected to the robotic prosthetic arm and introduced a rotation module. As a result, they successfully developed a prosthetic that moves more naturally and smoothly, with over a 30% improvement in functionality compared to existing prosthetics.

Professor Sei Kwang Hahn’s research team analyzed the impact of trapped electrons and recharging on the emission and disappearance of light, uncovering the underlying mechanism. Based on this, they developed an optical display technology that allows users to write on the touchscreen with a small force from a fi nger press and erase the writing using ultraviolet light, similar to using an eraser.

Professor Soojin Park’s research team irradiated gel-type electrolytes with electron beams to form covalent bonds between micro-silicon particles and the gel electrolyte, dispersing internal stress caused by volume expansion. This silicon-gel electrolyte system, which enhances energy density by 40%, features a simple process and can be immediately applied.

Electrostatic sensors, which utilize static electricity, do not require external power and are gaining attention as next-generation power sources for electronic skin and medical sensors. Professor Jin Gon Kim and Professor Unyong Jeong’s research team successfully increased the electrostatic duration by approximately 30 times compared to previous methods by using ultraviolet light to create "deep traps" that limit the movement of charges.

Professor Won Bae Kim’s research team developed a catalyst that improves the effi ciency of eco-friendly green ammonia production through oxygen vacancy control and heteroatom doping. This technology is considered an effective and selective method for producing green ammonia.

Professor Seung-Woo Lee’s research team developed a new drug candidate for preventing and treating major respiratory viral infections. They focused on the long-acting recombinant cytokine protein rhIL-7-hyFc (NT-17), currently under clinical development as an immunotherapy, which can activate various immune cells in the respiratory system.

Professor Chulhong Kim and Professor Won Jong Kim’s research team successfully used 3D multi-parametric photoacoustic tomography technology, which can obtain structural and functional information of cells and molecules, to identify the location of metastatic cancer and changes in the surrounding microstructure without surgery.

Professor Su Seok Choi’s research team developed the fi rst-ever technology for creating stretchable artifi cial skin that can change from a single color to multiple colors, similar to a chameleon’s skin. This innovative technology uses chiral structures in optical elastomers and electrical stimuli. It is expected to have a wide range of applications, including in electronic skin, next-generation displays, encryption, biomimetic soft robots, and more.
