The organic framework of molluscan and barnacle shells yields clues to biocalcification processes. Slight demineralization of the shells reveals the fragile meshwork of insoluble organic fibers and membranes, which tend to collapse, wrinkle, and shrink when air-dried from water. Comparison of different drying techniques on etched bivalve mollusk (Chione fluctifraga) and barnacle shells (Chthamalus sp.) reveals that hexamethyldisilazane (HMDS,) produced results qualitatively superior to critic...The organic framework of molluscan and barnacle shells yields clues to biocalcification processes. Slight demineralization of the shells reveals the fragile meshwork of insoluble organic fibers and membranes, which tend to collapse, wrinkle, and shrink when air-dried from water. Comparison of different drying techniques on etched bivalve mollusk (Chione fluctifraga) and barnacle shells (Chthamalus sp.) reveals that hexamethyldisilazane (HMDS,) produced results qualitatively superior to critical point drying or drying from ethyl alcohol or water. HMDS dries structural details of the organic meshwork excellently and facilitates the recognition of faint growth increments for growth pattern analysis (sclerochronology). The HMDS method is cost-effective, saves time and can be used as a routine substitute for drying microstructures in slightly etched molluscan and barnacle shells.» weiterlesen» einklappen
