Quartz resonator as microbalance for chemical sensing.

Quartz solubility dependence on fill

Quartz structure projected along axis z. Filled dots are Si atoms .

Quartz subboiling still with inflated heating and a cold-finger condenser.

Quartz tube for mineralization

Quartz tube for oxidation of praseodymium oxide.

Quartz tube for preparing macrocrystalline iron oxide

Quartz tuning fork with a goid-tip glued at one of the prongs used shear-force for tip-sampie distance control. Typical vibration amplitudes are on the order of 0.1 nm. Adapted from PhD-Thesis of Marcus Sackrow, University of Tubingen.

Quartz vein showing a comb-hke texture.

Quartz vein with visible gold. Sample is from DDH WB-8-11 22.43 m.

Quartz-spiral manometer, Boden-stein type.

Quartz-spoon-gauge type vapor pressure measuring apparatus with counterpressure arrangement.

Quartz. Chalcedony, a fibrous variety of quartz at 120X magnification. Bundles of twisted fibrils of Si02 in parallel alignment display an alternating black-and-white pattern along their length. The pattern indicates the irregular but twisted nature of the Si02 bundles.

Quasi 2-dimensional layered semiconductors. The structure of SnS2 is shown as a representative system. The large separation between the planes is due to the weak van der Waals forces holding the crystal together. The carriers are very strongly localised in the plane in these systems.

Quasi phase matching

Quasi steady state polarization curves 1.

Quasi steady state voltammetric curve of NaCl-KCl-K2TaF7melt. Apt 0,31 cm,

Quasi-2D rotating drum. Spherical stainless steel ball bearings are in between two glass plates separated by 1.01 particle diameters D 3.175 mm. The diameter of the drum is 128D 152.4 mm. squares shown in the central image.

Quasi-3D flow structures for the choking transition at lower part of a CFB riser .

Quasi-A-values for methyl-substitution of cyclooctane .

Quasi-arbitrary voltage waveform generated inside LabVIEW and used for the AWG hardware of the system top digital signal used to turn the discharge switch on bottom 2012 IEEE

Quasi-bin2ury cube for carbon dioxide hexadecane
