A research team led by Prof. Jintao Zhang (School of Chemistry and Chemical Engineering, Shandong University) demonstrates the in-situ loading of molybdenum carbide nanoclusters (MoC) and zinc single atoms (Zn-SA) within porous carbon fibers to invoke the electrocatalytic conversion of iodine at the interface, providing robust guidance for constructing advanced iodine catalysts and optimizing their battery performance.
In the solar system, Icy Worlds such as Europa and Enceladus hold great potential for extraterrestrial life and may provide humanity an answer, within this century, to the age-old question of life beyond Earth. Exo-AUV technology shows promise in life detection in the icy shell, at the ice-water interface and on the seafloor of Exo-ocean. Space agencies, including NASA and DLR, are enthusiastic about deploying Exo-AUVs to explore life in these regions. However, the where and how to find life, the technologies to be utilized and the goals to be achieved are crucial aspects for future Exo-AUV life detection missions on Icy Worlds. This study delves into a hypothetical mission of life detection on Europa, discussing science goals, detectable objects, potential regions and biogenic analysis for Icy Worlds. It proposes a life detection strategy for Icy Worlds based on Exo-AUVs, presents key contextual elements for Exo-AUV operations, outlines technological requirements for hull, payloads and autonomy, introduces the current state of Exo-AUV research and addresses existing challenges. This study also suggests a roadmap for conceptual development of Exo-AUV and a Concept of Operations for Multiple Exo-AUV System (ConOps for MEAS). This system aims to assist planetary scientists and astrobiologists in exploring Icy Worlds, identifying robust biosignatures and potentially discovering extant organisms, even prebiotic chemical systems.
Scientists lead by EPFL, the University of Copenhagen, and Shanghai University have developed a copper catalyst that can efficiently convert carbon dioxide into acetaldehyde, a key chemical used in manufacturing. The breakthrough offers a green alternative to fossil-fuel-based processes.
Scientists including an Oregon State University chemistry researcher have taken a key step toward next-generation optical computing and memory with the discovery of luminescent nanocrystals that can be quickly toggled from light to dark and back again.
