CHANGWON, South Korea — A research team led by Principal Researcher Myungkwan Song of the Energy & Environment Materials Research Division at the Korea Institute of Materials Science (KIMS), headed by President Chul-jin Choi, has developed an ultrasensitive ammonia gas sensor using an environmentally friendly, lead-free perovskite material. The research was conducted in collaboration with teams led by Professor Hyung Woo Lee of Pusan National University, Professor Youngho Kang of Incheon National University, and Professor Jincheol Kim of Macquarie University in Australia. In addition to developing the high-performance sensor, the researchers elucidated, for the first time, the mechanism by which it detects ammonia, providing a new direction for the development of next-generation perovskite-based gas sensors. The technology is expected to serve as a key gas-detection solution for improving safety in an emerging hydrogen economy that uses ammonia as an energy carrier.
A research team from Botswana International University of Science and Technology has developed a deep reinforcement learning framework to estimate network latency in telesurgery systems. The method uses a deep Q-network agent to first predict whether latency will increase or decrease and then translate that directional signal into a quantitative delay forecast. Tested on simulated teleoperation latency data, the framework achieved 85.8% direction prediction accuracy, a 35.8% improvement over a random classifier, as well as 7.23% mean absolute percentage error and 92.55% value accuracy for latency estimation. By providing both direction and value information, the approach may help future telesurgical systems anticipate changing network conditions and improve resilience during remote surgical operation.
- Professor Sarah Park’s research team in the Department of Chemistry develops a new electrode material that sequentially stores zinc ions and protons (H⁺)
- By controlling the storage sequence, protons are harnessed for additional energy storage, offering the potential for high capacity and rapid charging and discharging
The NHS 10 year Health Plan “risks propagating patient harm at an unprecedented scale” due to the lack of appropriate safety architecture to support the envisaged digital transformation, warn experts in an analysis published in the online journal BMJ Innovations.
