WebBasic principles [ edit] Cryo crystallography enables X-ray data collection at cryogenic temperatures, typically 100K. Crystals are transferred from the solution they have grown in (called mother liquor) to a solution with a cryo-protectant to prevent ice formation. Crystals are mounted in a glass fiber (as opposed to a capillary.) WebSep 19, 2012 · Figure 1. I. I. Shafronovski’s History of Crystallography, XIXth Century, Volume 2. German texts dominated the 19 th century literature on the history of crystallography, especially those of Marx (1794-1864) and Kobell (1803-1882). Marx’s Geschichte der Kristallkunde (1825) was valued by Shafranovskii because of its …
