  • Real-Time Gas Analysis and Reaction Monitoring using Mass Spectrometry

    Gas chromatographs are commonplace in labs worldwide as workhorse instruments for the identification and purification of unknown chemical compounds. However, despite the abilities of gas chromatography (GC), GC alone cannot always be used for the specific identification of chemical compounds. As a result, such instruments are often coupled to mass spectrometers, where the ability to mass-resolve ...

  • Weather extremes provoked by trapping of giant waves in the atmosphere

    “An important part of the global air motion in the mid-latitudes of the Earth normally takes the form of waves wandering around the planet, oscillating between the tropical and the Arctic regions. So when they swing up, these waves suck warm air from the tropics to Europe, Russia, or the US, and when they swing down, they do the same thing with cold air ...
