The first two minutes is a recap of things you already know. But after that [Steve] gets into the crystal lattice structure of quartz. Using some computer animations and some peanut butter lids he shows you exactly why compressing the crystal generates electricity. ...
Crystal Structure and Vibrational Spectrum of Dipotassium Manganese(II) Hexathiodiphosphate(IV), K2Mn[P2S6] K 2 Mn[P 2 S 6 ] was synthesized from the elements in sealed quartz ampoules at 1 173 K. The compound forms transparent light brown crystals, stable agains... F Menzel,W Brockner,...

The BT-cut quartz crystal has a similar structure to the AT-cut crystal but is intended to function at a higher frequency. It is utilized in processes that call for a high-frequency signal, such as wireless transmission and digital signal processing. ...
The structure of quartz is made up of SiO4 tetrahedra, which are linked by sharing each of their corners with another tetrahedron. In the three-dimensional framework thus formed, every Si4+ has four oxygens and every oxygen has two silicons as nearest neighbors. There are several works on ...
(SiO2), which has seven different structures at various temperatures and pressures; the most common of these structures isquartz. Some pairs of elements form several different crystals in which the ions have different chemical valences.Cadmium(Cd) andphosphorus(P) form the crystals Cd3P2, CdP2,...
Quartz Crystal Microbalance(QCM) is amass sensitive devicethat can measure particles in the range of nanograms to micrograms, thus suitable for low concentration level gas detection applications. As illustrated inFig. 7, the structure of QCM consists of an AT-cut piezoelectricquartz crystalsandwiched...
The thermal expansion of a crystal structure can often be expressed empirically as a linear combination of the expansions of its constituent parts; and these can be estimated by comparison with other simpler structures. In particular, the expansion of a three-dimensional framework is the sum of a...
