Stretchable electronics have broad applications, including wearable sensors and curved displays. However, the electronic performance of stretchable materials is poor in comparison to non-stretchable rigid electronic materials. In a new study, researchers have developed a new technique, using kiri-origami structures, that combines the benefits of both origami and kirigami to achieve stretchable devices with high-performance non-stretchable materials. This innovative technique can lead to the development of advanced stretchable electronic devices.

In the Materials Horizons Emerging Investigator Series, Dr. Eunho Lee from SeoulTech talks about his recent study on novel organic semiconductor materials with glycol side chains that enhance artificial synapses by shifting from surface-limited to bulk-mediated ion transport mechanisms. The research demonstrates how molecular design of conjugated polymers can improve synaptic performance in neuromorphic computing devices, offering pathways toward brain-inspired artificial intelligence hardware.

Embedded systems such as Internet of Things (IoT) devices and single-board computers require careful memory allocation management. In a recent breakthrough, SeoulTech researchers have proposed LWMalloc, a lightweight dynamic memory allocator designed for resource-constrained environments like IoT devices and embedded systems. The research demonstrates up to 53% faster execution times and 23% lower memory usage compared to Linux's default allocator, while requiring only 530 lines of code versus ptmalloc's 4,838 lines.

An international team led by Dr. Hila Glanz of the Technion – Israel Institute of Technology has uncovered a new origin for hypervelocity white dwarfs — stellar remnants racing through space at more than 2000 km/s.

Using advanced 3D hydrodynamic simulations, the researchers showed that when two rare hybrid white dwarfs merge, the heavier star can undergo a double-detonation explosion. This blast ejects the surviving remnant of its companion at hypervelocity, fast enough to escape the Milky Way.

The findings, published in Nature Astronomy, explain both the extreme speeds and unusual properties of known hypervelocity white dwarfs, while also pointing to a new pathway for faint and peculiar Type Ia supernovae.

The study was conducted by researchers from the Technion, Universität Potsdam, and the Max Planck Institute for Astrophysics, and has implications for future transient surveys and Gaia discoveries.
