Russia's MEPhI Electrospray Ionization Triple Quadrupole Mass Spectrometer Listed in Russia's Key Scientific Instrumentation Projects

According to the 2025 activity report recently released by the Russian Ministry of Science and Higher Education, the triple quadrupole mass spectrometer with electrospray ionization developed by the National Research Nuclear University MEPhI (Moscow Engineering Physics Institute) has been listed as one of the 8 successful projects under the federal program "Development of Domestic Civil Instrumentation for Scientific Research." The mass spectrometer, developed under the guidance of MEPhI Professor Alexey Sysoev, is primarily used for quantitative analysis and identification of chemical substances, particularly suitable for identifying relevant components in complex mixtures. Previously, all such instruments on the Russian market were imported. This independently developed chromatography-mass spectrometry system can handle...

U.S. Research Team Tracks Main Drivers of Global Methane Rise Using Stable Isotope Analysis

A research team from the U.S. National Oceanic and Atmospheric Administration Global Monitoring Laboratory and the University of Colorado has recently traced the sources of the rapid rise in global atmospheric methane since 2007 through high-precision methane concentration measurements and carbon and hydrogen stable isotope analysis. The findings show that over the past two decades, microbial emissions have been the primary factor driving the increase in methane concentrations, while fossil fuel-related methane emissions may have remained relatively stable overall. A methane molecule consists of one carbon atom and four hydrogen atoms, and methane from different sources differs in its carbon and hydrogen isotope composition. Researchers used this chemical fingerprint to distinguish methane sources: fossil fuel methane such as natural gas typically contains a relatively higher proportion of carbon-13, while methane produced by microbial processes in wetlands, landfills, livestock, and agricultural environments has a lower carbon-13 proportion, exhibiting a "lighter" isotopic signature. The proportion of deuterium in hydrogen isotopes also varies with the way methane is formed, providing a further basis for source identification.

Joint Safety Inspection of Directly Managed Nuclear Technology Utilization Units in Shandong by East China and North China Nuclear and Radiation Safety Supervision Stations

To thoroughly implement General Secretary Xi Jinping's important directive on the Quanzhou shoe factory fire accident, which calls for "in-depth investigation and rectification of various risk hazards, meticulous implementation of safety production measures, and resolute prevention of major and catastrophic accidents," the Ministry of Ecology and Environment's East China Nuclear and Radiation Safety Supervision Station (hereinafter referred to as the East China Station) recently joined forces with the North China Nuclear and Radiation Safety Supervision Station (hereinafter referred to as the North China Station) to take swift action. Together, they formed a joint inspection team to conduct safety inspections on some of the Ministry of Ecology and Environment's directly managed nuclear technology utilization units in Shandong Province. Shandong currently has 19 such units directly managed by the Ministry of Ecology and Environment, making it a major province in nuclear technology utilization. To ensure that this joint inspection achieves the goal of identifying...

South China Regional Office of the National Nuclear Safety Administration Conducts Special Supervision and Inspection of Changjiang Units Under Construction

As the South China region enters the main flood season with concentrated typhoons and heavy rainfall, nuclear facilities face significant pressure in resisting meteorological disasters, and safety control responsibilities are critical. To rigorously prevent nuclear safety risks triggered by natural disasters during the flood season and to reinforce the primary responsibility of operating entities for safety production, the South China Regional Office of the National Nuclear Safety Administration (hereinafter referred to as the South China Regional Office) made advance deployments and carried out a special supervision and inspection of typhoon and flood prevention for the Changjiang units under construction in an unannounced manner. This inspection comprehensively verified the effectiveness of control measures, tightened the primary responsibility of the operating entity, and effectively built a safety barrier for nuclear facilities during the flood season. Inspectors went deep into the construction sites of Units 3 and 4 of the Changjiang Nuclear Power Plant and the small modular reactor demonstration project, focusing on checking nuclear...
