A "'radiolarian chert "'is well-bedded, microcrystalline radiolarite that has a well-developed siliceous cement or groundmass.
42.
The two junctions consist of the amorphous silicon ( a-Si ) top cell and the microcrystalline silicon ( ?c-Si ) bottom cell.
43.
In contrast to the first member it is composed either of micrites that are slightly debris-bearing, or of microcrystalline limestones rich in debris.
44.
"' Chert "'( ) is a fine-grained silica-rich microcrystalline or cryptocrystalline sedimentary rock that may contain small fossils.
45.
The company stated that its amorphous / microcrystalline design enables module performance by capturing up to 50 % more sunlight than conventional thin film silicon PV modules.
46.
:: The article on gum base describes this, and alas, it appears so-paraffin, microcrystalline wax, even potentially hazardous vinyl acetate.
47.
Amorphous particles usually adopt a spherical shape ( due to their microstructural isotropy ), whereas the shape of anisotropic microcrystalline whiskers corresponds to their particular crystal habit.
48.
"' Powder diffraction "'is a scientific technique using neutron, or electron diffraction on powder or microcrystalline samples for structural characterization of materials.
49.
When paired with microcrystalline silicon in tandem and triple-junction solar cells, however, higher efficiency can be attained than with single-junction solar cells.
50.
The lower formation finishes with a few metres of thinly bedded, yellowish, " microcrystalline limestone " rich in bioclasts ( lamellibranchs and echinoderms ).
