Hydrogen propulsion systems have emerged as a sustainable and more eco-friendly alternatives for unmanned aerial vehicles (UAVs). Despite extensive research, previous studies focused on standalone performance evaluations for liquid hydrogen storage systems in UAVs. In a new study, researchers have developed an integrated analytical framework for evaluating thermal performance and structural integrity of liquid hydrogen storage systems, tailored to UAV-specific operation conditions. This study could serve as reference for establishing design criteria for hydrogen-powered UAVs.

Scientists from the German Federal Institute for Materials Research and Testing (BAM), in collaboration with DESY, have developed a promising new filter material to remove harmful PFAS “forever chemicals” from wastewater. These filters are made from covalent organic frameworks (COFs) produced using a sustainable mechanochemical process involving a high-speed ball mill. Real-time experiments at DESY’s PETRA III X-ray facility helped optimize the production technique, enabling the team to observe the filter material forming at the molecular level. The new filters are metal-free, environmentally friendly, and could eventually be used in industrial wastewater systems or even household taps.

A research team led by Prof. DANG Shangyu from the Division of Life Science at the Hong Kong University of Science and Technology (HKUST) has developed a novel vesicle-based method that preserves the native lipid environment of membrane proteins, which can advance structural and functional studies.

In two recent studies, University of Texas at Dallas researchers demonstrated how artificial intelligence (AI) and machine learning can be used to address a variety of issues from a social science policy perspective.
