Multioperation‐Mode Light‐Emitting Field‐Effect Transistors Based on van der Waals Heterostructure
Prof. Gwan‐Hyoung Lee
2D semiconductors have shown great potential for application to electrically tunable optoelectronics.

DNA Micro‐Disks for the Management of DNA‐Based Data Storage with Index and Write‐Once–Read‐Many (WORM) Memory Features
Prof. Sunghoon Kwon
DNA‐based data storage has attracted attention because of its higher physical density of the data and longer retention time than those of conventional digital data storage. However, previous DNA‐based data storage lacked index features and the data quality of storage after a single access was not preserved, obstructing...

Novel laser-thermal mechanism realizes ultra-fast construction of PDMS devices
Prof. Seung Hwan Ko
Researchers at Seoul National University in South Korea reported the development of new laser-based polydimethylsiloxane (PDMS) processing mechanism that enables the mask-less direct fabrication of various PDMS structures.

Rhizolutin, a novel 7/10/6‐tricyclic dilactone, dissociates misfolded protein aggregates and reduces apoptosis/inflammation associated with Alzheimer’s disease
Prof. Dong-Chan Oh
Rhizolutin ( 1 ) was discovered as a natural product of ginseng‐rhizospheric Streptomyces sp. WON17. Its structure featured an unprecedented 7/10/6‐tricyclic dilactone carbon skeleton composed of dimethylcyclodecatriene flanked by a 7‐membered and a 6‐membered lactone ring based on spectroscopic analysis. During an unb...

A Large‐Scale Array of Ordered Graphene‐Sandwiched Chambers for Quantitative Liquid‐Phase Transmission Electron Microscopy
Prof. Jungwon Park
Liquid‐phase transmission electron microscopy (TEM) offers a real‐time microscopic observation of the nanometer scale for understanding the underlying mechanisms of the growth, etching, and interactions of colloidal nanoparticles. Despite such unique capability and potential application in diverse fields of analytical ...

Monolithic digital patterning of polydimethylsiloxane with successive laser pyrolysis
Prof. Seung Hwan Ko & Prof. Noo Li Jeon
The patterning of polydimethylsiloxane (PDMS) into complex two-dimensional (2D) or 3D shapes is a crucial step for diverse applications based on soft lithography. Nevertheless, mould replication that incorporates time-consuming and costly photolithography processes still remains the dominant technology in the field. He...

Quantum distance and anomalous Landau levels of flat bands
Prof. Bohm-Jung Yang
Semiclassical quantization of electronic states under a magnetic field, as proposed by Onsager, describes not only the Landau level spectrum but also the geometric responses of metals under a magnetic field. Even in graphene with relativistic energy dispersion, Onsager’s rule correctly describes the π Berry phase, as w...

Urolithin A suppresses high glucose-induced neuronal amyloidogenesis by modulating TGM2-dependent ER-mitochondria contacts and calcium homeostasis
Prof. Ho Jae Han
Hyperglycemia in diabetes mellitus (DM) patients is a causative factor for amyloidogenesis and induces neuropathological changes, such as impaired neuronal integrity, neurodegeneration, and cognitive impairment.

Resource-Efficient Topological Fault-Tolerant Quantum Computation with Hybrid Entanglement of Light
Prof. Hyunseok Jeong
We propose an all-linear-optical scheme to ballistically generate a cluster state for measurement-based topological fault-tolerant quantum computation using hybrid photonic qubits entangled in a continuous-discrete domain.

Topological Hyperbolic Lattices
Prof. Namkyoo Park
Non-Euclidean geometry, discovered by negating Euclid’s parallel postulate, has been of considerable interest in mathematics and related fields for the description of geographical coordinates, Internet infrastructures, and the general theory of relativity.

Water Passivation of Perovskite Nanocrystals Enables Air‐Stable Intrinsically Stretchable Color‐Conversion Layers for Stretchable Displays
Prof. Tae-Woo Lee
Conventional organic light‐emitting devices without an encapsulation layer are susceptible to degradation when exposed to air, so realization of air‐stable intrinsically‐stretchable display is a great challenge because the protection of the devices against penetration of moisture and oxygen is even more difficult under stretching.

Coherent many-body exciton in van der Waals antiferromagnet NiPS3
Prof. Je-Geun Park
An exciton is the bosonic quasiparticle of electron–hole pairs bound by the Coulomb interaction. Bose–Einstein condensation of this exciton state has long been the subject of speculation in various model systems, and examples have been found more recently in optical lattices and two-dimensional materials.
