POSTECH-KRISO team develops an ultra-light underwater lens for broadband low-frequency sound focusing.

POSTECH Identifies True Cause of Prussian Blue Performance Loss — Surface Oxidation, Not Crystal Water, Is the Key Factor.

A research group has developed “TP-An,” a molecule that enables even low-energy, long-wavelength light to be used more effectively by solar cells and photocatalysts. The molecule can be used even at high concentrations that are difficult for traditional materials, suggesting their usefulness in technology.

A Korean research team has developed a new viral vector technology that significantly improves the production efficiency of next-generation cell and gene therapies known as CAR immune cell therapies, which are designed to recognize and destroy cancer cells. Dr. Chi Hoon Park and his research team at the Korea Research Institute of Chemical Technology (KRICT) discovered a novel envelope protein derived from Simian Retrovirus Type 2 (SRV2). The newly identified SRV2 envelope protein demonstrated superior performance compared with the widely used RD114 envelope protein derived from feline endogenous retrovirus, highlighting its potential for future large-scale manufacturing of CAR immune cell therapies.

A research team led by Professors Jiafu Wang and Jue Qu has jointly developed an eye-tracking-driven, polarization-agile, and beam-programmable metasurface. This system integrates high-precision eye-tracking technology with advanced programmable metasurface design, enabling real-time 3D beam focusing and adaptive reconfiguration of polarization modes for wireless communication signals. This achievement was published in Research under the title "Eye-Tracking-Driven Programming Metasurface System for Adaptive Beam Focusing and Polarization-agile Communication".

A new study shows that older adults’ perceptions of their mental sharpness closely align with their actual cognitive performance. The findings may help clinicians better understand and support patients.

Organic molecular crystals can respond to external stimuli such as heat, light, and mechanical force, making them attractive candidates for next-generation functional materials. However, predicting how multiple intermolecular interactions cooperate or compete to govern crystal behavior remains a major challenge. Now, researchers at Kochi University of Technology have demonstrated that the hierarchy of intermolecular interactions—the relative strength and priority of different molecular forces—can determine crystal structures, luminescence properties, and even phase-transition pathways in molecular crystals. Their findings provide a new design principle for controlling solid-state functions through molecular engineering. The study was conducted by Mahiro Nakabayashi and Professor Shotaro Hayashi and published in Angewandte Chemie International Edition.
