South Korean Researchers Discover Potential New Approach to Cancer Treatment

Researchers have discovered a novel quantum state that can significantly improve the reliability of quantum information processing, according to a study published in Nano Letters. This new state, termed the exciton-Floquet synthesis state, was observed using ultrathin two-dimensional (2D) semiconductor materials, which allow for easier maintenance of quantum coherence compared to traditional three-dimensional structures. The breakthrough hinges on the formation of excitons—quasi-particles formed when photons excite electrons—and their interaction with Floquet states. These findings suggest potential for more stable quantum computing technologies that could outperform existing methods hampered by decoherence from thermal and electromagnetic disturbances, a common issue with 3D systems. Jaedong Lee from Daegu Gyeongbuk Institute of Science and Technology noted, “This discovery is anticipated to drive forward quantum information technology research," emphasizing its implications for developing reconfigurable data storage in quantum computers. Although challenges remain regarding the transient nature of these new quantum states, the study opens up pathways for advanced applications in the field of quantum computing.

Researchers from Pohang University of Science and Technology in South Korea announced a significant advancement in lithium-ion battery technology that could enhance energy retention and durability. According to a lab summary by Tech Xplore, this breakthrough involves the use of lithium-rich layered oxide as a cathode material, which has been shown to increase energy density by up to 20% compared to traditional nickel-based batteries. The team focused on addressing the common issues of capacity fading and voltage decay that have hindered the commercial viability of these batteries. By modifying the electrolyte composition, they effectively reduced oxygen release at the cathode interface, which substantially improves battery performance. Their results indicate an 84.3% energy retention rate after 700 charge-discharge cycles, compared to just 37.1% for traditional versions after 300 cycles. As innovations continue in battery technology, experts believe these findings could pave the way for cleaner, more efficient energy solutions for electric vehicles and renewable energy storage, according to Professor Jihyun Hong.

Researchers at South Korea's Pohang University of Science and Technology have made a significant advancement in lithium-ion battery technology, potentially enhancing energy retention and durability. According to a report by Tech Xplore, the team focused on a lithium-rich layered oxide material to improve battery performance, aiming to address issues of capacity fading and voltage decay that have impeded commercial viability. The new cathode design, which includes modifications to the electrolyte, boosted energy retention to 84.3% after 700 charge/discharge cycles, compared to just 37.1% for traditional nickel-based batteries after 300 cycles. This innovation not only increases energy density by up to 20% but also makes the technology more economical and sustainable by reducing reliance on nickel and cobalt, as noted by the researchers. Professor Jihyun Hong emphasized the potential impact of this research, stating, “We believe this work will provide new directions for developing next-generation cathode materials.” The findings could significantly contribute to the future of electric vehicles and renewable energy storage.
