We present the first clearly resolved observations of surfaces of growing and ablating hexagonal ice crystals using variable-pressure scanning electron microscopy. The ice surface develops trans-prism...
The eggs of Megistopus flavicornis (Rossi, 1790) and Macronemurus bilineatus Brauer, 1868 were studied by light and scanning electron microscope and are described in detail in this paper. Both species...
A number of records of rotifers from Turkey are discussed. An account is given on trophi morphology in 4 species of Asplanchna Gosse, 1850. Cephalodella segersi De Smet, 1998 is recorded for the secon...
Detailed exine sculpturing of the pollen of 32 Turkish Teucrium L. (Labiatae) taxa has been investigated under SEM. Two main exine sculpturing types, verrucate (in sections Teucrium, Scordium, Boiss, ...
Thin sections of breast tissues from patients with possible tumors also contained closely associated mineral deposits. Using scanning electron and backscattered electron micros-copy (SEM-BSE) energy a...
The morphology of illite/smectite (I/S) from deeply buried bentonites and hydrothermally altered Tertiary volcanic rocks from Japan changes in parallel with the proportion of expandable layers in the ...
Morphological changes occurring in naturally weathered micas in seven residual soils from Ontario were studied. Splitting, exfoliation of the (100) planes, surface coats, filling of spaces with soil m...
Scanning electron microscopic (SEM) examination of the quartz isolated from chert of Transvaal and Swaziland, of 2000 and 3400 million year (MY) ages, respectively, in southern Africa revealed marked ...
Quartz isolated from soils by the pyrosulfate-H2SiF6 method and chert samples of various origins were examined with the scanning electron microscope. Quartz isolates of the 20?0 祄 from the A2 and B2lt...
