POSTECH-led research team develops IrFe/C electrocatalyst that self-heals after oxidation, dramatically improving durability of water electrolyzers and fuel cells.

Recently, a research team led by Professor Junbo Yang at the National University of Defense Technology has proposed a novel permittivity regulation framework based on programmable interface atomic rearrangement. They developed an Ag-In₃SbTe₂ (IST) interface atomic rearrangement metamaterial (ARM), enabling full-spectrum and time-domain dynamic modulation, as well as spatiotemporal thermal radiation tailoring. The ARM exhibits broad and continuous spectral tunability, with modulation amplitudes reaching 64.74% in the 3-5 μm band and 73.94% in the 8-14 μm band, accompanied by rich temporal variations.

The research team led by Professor Hoseok Park of the Department of Chemical Engineering of SKKU announced that they have succeeded in dramatically improving the cycle life and capacity of aqueous batteries simply by adding a small amount of a special material to the electrolyte.

New “GMBU” procedure reveals band structures in finite, curved nanomaterials, linking nano‑ARPES and theory for next‑generation device design.

Fuel cell buses are a promising route toward cleaner public transport, but their real-world efficiency depends on more than the vehicle powertrain alone. A study in Green Energy and Intelligent Transportation presents a hierarchical predictive energy management strategy that uses traffic information around bus stops to guide how fuel cell buses plan battery state of charge and allocate power as they approach stopping events.

Dyes are used to colour papers, leather products, garments, and are also employed in the rubber and cosmetic industries. But what happens after these dyes have served their purpose? Billions of tons of dye-containing wastewater enter water systems every year, eventually rendering them unfit for human and animal use. They can also lead to serious health issues such as breathing problems, jaundice, and cancer. As an effort to tackle this issue, researchers have developed advanced materials, which act like microscopic sponges, as a promising solution to industrial wastewater treatment. 

Researchers have developed a comprehensive numerical model for liquid metal batteries that captures potential, mass transfer, and species distribution while remaining fast enough to support practical battery management. The work could help bring greater precision to how these emerging batteries are monitored, controlled, and optimized, especially in long-duration energy storage applications where both safety and lifespan are critical.

A chromosome-level genome has opened a new window into how Hemsleya ellipsoidea, a medicinal cucurbit known as Xuedan, evolved its unusual ability to accumulate cucurbitacin IIa (CuIIa), a bioactive triterpenoid associated with anti-inflammatory and antibacterial activities.
