Harnessing nanoscale magnetic spins to overcome the limits of conventional electronics

Researchers at Kyushu University have shown that careful engineering of materials interfaces can unlock new applications for nanoscale magnetic spins, overcoming the limits of conventional electronics. Their findings, published in APL Materials, open up a promising path for tackling a key challenge in the field and ushering in a new era of next-generation information devices.

The study centers around magnetic skyrmions—swirling, nanoscale magnetic structures that behave like particles. Skyrmions possess three key features that make them useful as data carriers in information devices: nanoscale size for high capacity, compatibility with high-speed operations in the GHz range, and the ability to be moved around with very low electrical currents.

A skyrmion-based device could, in theory, surpass modern electronics in applications such as large-scale AI computing, Internet of Things (IoT), and other big data applications.

2D material offers a solution to long-standing obstacle in diamond-based circuits

Beyond their sparkle, diamonds have hidden talents. They shed heat better than any material, tolerate extreme temperatures and radiation, and handle high voltages while wasting almost no electricity—ideal traits for compact, high-power devices. These properties make diamond-based electronics promising for applications in the power grid, industrial power switches, and places with high radiation, such as space or nuclear reactors.

Diamond’s ability to quickly carry heat away from electronic components allows devices to handle large currents and voltages without overheating. This means smaller devices can be used to switch to high power in the grid or in industrial settings. Diamond’s natural resistance to radiation and extreme temperatures could enable electronics to work reliably in places where traditional silicon devices fail.

The art of custom-intercalating 42 metals into layered titanates

A research team affiliated with UNIST has reported a novel synthesis strategy that enables the direct intercalation of a wide range of metal cations into the interlayer spaces of layered titanate (LT) structures. This approach opens new possibilities for designing highly tailored catalysts and energy storage materials for specific industrial applications.

Professors Seungho Cho (Department of Materials Science and Engineering), Kwangjin An (School of Energy and Chemical Engineering), and Hu Young Jeong (Graduate School of Semiconductor Materials and Devices Engineering) at UNIST, in collaboration with Professor Jeong Woo Han from Seoul National University, report this advancement in Advanced Materials.

Nanoparticles That Destroy Disease Proteins Could Unlock New Treatments for Dementia and Cancer

Scientists have developed a new nanoparticle-based strategy that could dramatically expand the range of disease-causing proteins that can be targeted by modern medicine. A newly released perspective in Nature Nanotechnology describes an emerging nanoparticle-based approach designed to remove harm

Scientists Uncover Hidden Weakness in Quantum Encryption

Quantum key distribution (QKD) is a next generation method for protecting digital communications by drawing on the fundamental behavior of quantum particles. Instead of relying on mathematical complexity alone, QKD allows two users to establish a shared secret key in a way that is inherently resistant to interception, even if the communication channel itself is not private.

When an unauthorized observer attempts to extract information, the quantum states carrying the data are unavoidably altered, creating telltale disturbances that signal a potential security breach.

The real-world performance of QKD systems, however, depends on precise control of the physical link between sender and receiver. One of the most influential factors is pointing error, which occurs when the transmitted beam does not perfectly align with the receiving device.
