Newswise — Superradiant Smith-Purcell radiation (S-SPR) is a kind of free electron radiation with a train of free electron bunches passing over a periodic grating. In theory, ultra-narrow spectral linewidth of S-SPR could be realized, which would be greatly beneficial to various applications such as imaging, sensing, communication, and et al. However, in the free…
Newswise — Chulalongkorn University has been recognized as the leading university in Thailand across 34 subjects in the QS University Rankings by Subject 2025, announced on March 12, 2025. Subjects ranked #1 in Thailand: Accounting & Finance Anthropology Architecture / Built Environment Arts & Humanities Business & Management Studies Chemistry Computer Science Dentistry Economics &…
Newswise — SAN DIEGO, March 25, 2025 — The upcoming U.S. Open has professional golfers and spectators looking forward to getting on the green. But the grass’ condition, regardless of a player’s skill, can drastically skew the chances of a winning putt. Now, scientists can slow the roll of a golf ball on a lightning-fast,…
The Science Newswise — Unlike the vast majority of elements, the rare earth element promethium has no stable isotopes, which means that it is constantly decaying, making it difficult to study. In this research, scientists created a pure sample of the isotope promethium-147. They bonded it with a molecule to form a stable complex in water. Next,…
BYLINE: Sunny Katseanes Newswise — While Joy Morin was an undergraduate intern at the Idaho National Laboratory (INL), she discovered her interest in developing nuclear fuels and technology. Her mentor recommended she pursue a graduate degree at Boise State University in materials and engineering to continue her research. Morin is now a graduate fellow and…
Newswise — Efficient carrier transport is essential for high-performance light-conversion devices, yet two-dimensional (2D) perovskites face significant challenges due to their quantum well (QW) structures. The inorganic perovskite layers, confined by organic cation spacers, exhibit high exciton binding energies that hinder the dissociation of excitons into free carriers. This limitation strongly affects carrier transport properties,…
Newswise — A world-first technology has been developed by introducing a roll-to-roll compatible flash process into secondary battery electrode manufacturing, significantly suppressing the performance degradation of thick electrodes. This breakthrough presents a new possibility of reducing battery costs by minimizing inactive materials and simplifying the manufacturing process while increasing energy density and capacity, making batteries…
The Science Newswise — Studying the properties of a material that is radioactive and rare is difficult. The elements that come after plutonium in the periodic table (called transplutonium elements) are both. The result is that scientists know relatively little about their chemical properties. Often researchers use non-radioactive lanthanide surrogates to extrapolate the properties of actinides…
Newswise — Water is unique. It is one of the only substances that can exist in nature as a solid, liquid and gas at the same time under ambient conditions (think of solid ice over a pond, which is liquid underneath while storm clouds float overhead). It is also one of the only substances whose…
