Immersion freezing of surface dust particles from Tengger Desert in China: effects of mineral composition and aging treatments on ice nucleating activity

Abstract. Mineral dust is a major source of ice nucleating particles (INPs) for mixed-phase clouds and thereby influences cloud properties, precipitation, and radiative forcing. However, the ice nucleation properties of natural dust and their response to atmospheric aging remain...

Native Mass Spectrometry-Based Proteoform Explicit Metrics System (PrEMS) Informs Structural Improvement of Artificial Photocyclase Enzymes

Abstract Directed evolution is a powerful strategy for enzyme engineering and has successfully enabled unique stereoselective biosynthesis of high-value organic molecules. Enantiomeric excess (ee) remains the gold standard to assess the enzyme performance, but only reflects the f...
