A sine wave is a geometric waveform that oscillates (moves up, down or side-to-side) periodically, and is defined by the function y = sin x. In other words, it is an s-shaped, smooth wave that oscillates above and below zero.

Lead zirconate titanate is an inorganic compound with the chemical formula Pb[ZrxTi1−x]O3 (0≤x≤1). Also called lead zirconium titanate, it is a ceramic perovskite material that shows a marked piezoelectric effect, meaning that the compound changes shape when an electric field is applied. It is used in a number of practical applications such as ultrasonic transducers and piezoelectric resonators. It is a white to off-white solid.

A piezoelectric resonator is an electronic component designed for electronic oscillators and filters.

Piezoelectric resonators are:

crystal resonators, see Crystal oscillator
polycrystalline resonators, see Ceramic resonator
MEMS oscillators

Channelling

Channelling is the process that constrains the path of a charged particle in a crystalline solid

Polycrystalline materials are solids that consist of many small crystals (the “grains”). The grains are separated by grain boundaries and normally have random crystallographic orientations. The size of the grains may vary from nanometers to millimeters.

The polycrystalline nanoparticles are modeled by means of subdivision of the nanoparticle volume into tightly bound single-crystal granules with randomly distributed directions of the easy anisotropy axes. ... It is practically absent for magnetically soft magnetite nanoparticle
