The article discusses the synthesis and characterization of a meso–meso β‐β β‐β triply linked subporphyrin dimer. The research was conducted by a team of scientists from Kyoto University and Yonsei University, focusing on the molecular structure and spectroscopic properties of the dimer.

A novel 2D crystalline framework named C2O, primarily composed of carbon and oxygen, has been synthesized and characterized. It features crown ether holes and demonstrates significant chemical stability and catalytic activity for CO2 fixation with epoxides. The C2O framework activates KI, enhancing the nucleophilicity of I– and resulting in high CO2 conversion rates. Modified versions of the framework, C2O-AGE and C2O-EEA, show even higher conversion rates, indicating the framework's potential for creating materials with diverse functionalities suitable for various applications.

The study focuses on the synthesis of regioselective halogenated isomers of neo-confused isosmaragdyrin and their use as building blocks for constructing multichromophoric porphyrinoids. These heterodyads exhibit highly efficient energy cascade from porphyrin to isosmaragdyrin, with energy transfer processes and rates dependent on the linking sites. The research provides opportunities for developing new materials for optoelectronic applications.

The study presents a development plan for a vision AI system aimed at enhancing productivity in industrial environments with challenging environmental control. A mobile robot, SPOT, developed by Boston Dynamics, was used to obtain high-quality learning and inspection images. The proposed AI system architecture addresses challenges in applying AI technology at industrial sites, demonstrated through experimentation and application at Hyundai Motor Company's Singapore plant. The research was supported by Hyundai Motor Company and aimed to improve real-time visual inspection of manual assembly processes in automobile manufacturing.

A nonlinear finite element model for axisymmetric bending of micro circular/annular plates under thermal and mechanical loading was developed using quasi-3D Reddy third-order shear deformation theory. The model accounts for material variation, porosity distributions, and geometrical nonlinearity, utilizing modified couple stress theory for strain gradient effects. The study investigates the effects of material and porosity distribution, microstructure-dependency, geometric nonlinearity, and boundary conditions on the bending response of functionally-graded porous microplates under thermomechanical loads.

The study presents a direct numerical simulation method for extracting material properties of thin metal films based on surface wrinkling on scotch tape. This method offers a simpler and more efficient alternative to conventional finite element method (FEM)-based simulations, reducing time and complexity. The paper details the theoretical background, FEM model, and simulation results, demonstrating the method's effectiveness in determining the elastic moduli of gold and aluminum thin films. The research was supported by various Korean government ministries and the Korea Institute of Science and Technology.

A multicentre, single-arm, open-label extension study evaluated the long-term efficacy, safety, and immunogenicity of the etanercept biosimilar LBEC0101 in Korean patients with rheumatoid arthritis. The study involved patients who had completed a 52-week phase III trial and either continued with LBEC0101 or switched from the reference product to LBEC0101 for an additional 48 weeks. Results showed sustained efficacy and acceptable safety after continued therapy or switching, with no new safety concerns or increased immunogenicity. The study supports LBEC0101 as a viable alternative to the reference etanercept, with potential benefits for healthcare systems due to cost advantages.
