An innovative accident-tolerant fuel cladding material with excellent corrosion resistance has been developed. This material can prevent hydrogen explosions even in severe accident conditions, thus significantly enhancing the safety of nuclear power plants.   During the Fukushima accident, a large amount of hydrogen was generated due to the rapid corrosion of Zircaloy fuel cladding, which resulted in hydro...

A KAIST research team led by Professor Keon Jae Lee demonstrates the transfer printing of a large number of micro-sized inorganic semiconductor chips through the selective modulation of micro-vacuum force.   MicroLEDs are a light source for next-generation displays that use inorganic LED chips with a size of less than 100 μm. MicroLEDs have attracted a great deal of attention due to their superior elec...

A joint research team has developed DeepECtransformer, an AI that can predict enzyme functions from protein sequences. The joint research team discovered previously unknown enzymes using the AI.   Enzymes are proteins that catalyze biological reactions. Identifying the function of each enzyme is essential to understanding the various chemical reactions that exist in living organisms and the metabolic char...

Vehicle routing problems, crucial to modern urban transportation and logistics systems, require complex modern optimization algorithms and a vast amount of computational resources. KAIST researchers have developed a new machine-learning-based algorithm that significantly outperforms traditional methods, demonstrating the potential to find exact optimal solutions and reduce computing time in large-scale vehicle r...

Prof. Yiyun Kang collaborates on Passage of Water, an art project with Google and NASA. Using data visualization from NASA's Grace and SWOT satellites, the immersive experience explores the causal link between climate change and the Earth's freshwater crisis through online and offline components.     Professor Yiyun Kang in the Department of Industrial Design at KAIST created a new artwork in collabor...

This study introduces a microspectrometer with a solid immersion grating for compact design and improved spectral resolution. The size is over 1,000 times smaller than conventional spectrometers while maintaining high resolution and sensitivity, which  spectroscopic applications demonstrated in handheld fruit maturity verification.   The spectrometer is actively used in various fields for non-destruct...
