In Situ X‑Ray Diffraction Study on Hydrate Formation at Low Temperature in a High Vacuum

The condition for incorporating simple gases with H 2 O to form clathrate hydrates in protosolar nebula is a subject of topical interest. Methane and carbon dioxide clathrate hydrates have been speculated to exist in outer solar system bodies, but they have eluded direct detection so far. We have constructed a low-temperature and high-vacuum system to prepare and study clathrate hydrates by in situ synchrotron X-ray diffraction experiments.Upon heating, we found clathrate hydrates can be obtained from the codeposition of methane or carbon dioxide with water outside the equilibrium thermodynamic stability region under high vacuum. We suggested that the hydrate formation is assisted by the phase transformations in the ice, which provide the necessary activation energy to increase the mobility of the guest and water molecules. The results provide a new perspective on how “metastable” gas hydrate can be formed.

m-cat Flyer English

Rotating magnetrons and adjustable magnet bars can be measured and analyzed exactly within the sputtering process for float glass coating. Defective magnetrons and magnet bars are identified early and reliably. The homogeneity of the layer thickness can be increased and a sputtering-through can be avoided.

cmos-magview Flyer English

The cmos-magview is a digital magneto-optical system for the fast and accurate visualization of magnetic stray field structures. The sensor system allows real-time stray field analyses and quality testing of magnetic materials. Magnetic stray fields of, for instance, magnetic stripe cards, magnetic encoders and di- and multi-pole magnets can be visualized. A comprehensive user Software illustrates the images in false color.
