Researchers present HEGAT, the first interpretable, fine-grained model that jointly predicts document-level event factuality and extracts evidential sentences, achieving SOTA on their refined EB-DEF-v2 corpus.

This review article systematically summarizes research progress on pressurized oxy-fuel combustion system designs, heat transfer mechanisms, combustion behavior, and pollutant emissions.

Researchers at the Department of Energy’s Oak Ridge National Laboratory have developed an innovative energy storage system design that introduces a safer, more efficient method for electrical charge transfer. This study advances fundamental understanding of how functional groups impact the mechanical and electrochemical performance of highly charged polyelectrolyte membranes — thin, charged polymer sheets that help control the movement of ions in energy devices.

Carbon dioxide, as a greenhouse gas, is expected to be converted into other useful substances by the electrocatalytic CO₂ reduction reaction (CO₂RR) technology. The electrocatalytic cell, or electrochemical cell, used to provide the experimental environment for CO₂RR plays an irreplaceable role in the study of this process and determines the success or failure of the measurements. In recent years, electrolytic cells that can be applied to in-situ/operational synchrotron radiation (SR) characterization techniques have gradually gained widespread attention. However, the design and understanding of electrolyte systems that can be applied to in-situ/operational SR technologies are still not sufficiently advanced. In this paper, the electrocatalytic cells used to study the CO₂RR processes with in-situ/operando SR techniques are briefly introduced, and the types and characteristics of the electrolytic cells are analyzed. The recent advancements of in situ/operando electrolytic cells are discussed using X-ray scattering, X-ray absorption spectroscopy (XAS), light vibration spectroscopy, and X-ray combined techniques. An outlook is provided on the future prospects of this research field. This review facilitates the understanding of the reduction process and electrocatalytic mechanism of CO₂RR at the atomic and molecular scales, providing insights for the design of electrolysis cells applicable to SR technologies and accelerating the development of more efficient and sustainable carbon negative technologies.
