phonon
A phonon is a quasiparticle, collective excitation in a periodic, elastic arrangement of atoms or molecules in condensed matter, specifically in solids and some liquids. In the context of optically trapped objects, the quantized vibration mode can be defined as phonons as long as the modal wavelength of the oscillation is smaller than the size of the object. A type of quasiparticle in physics, a phonon is an excited state in the quantum mechanical quantization of the modes of vibrations for elastic structures of interacting particles. Phonons can be thought of as quantized sound waves, similar

desomorphine
Desomorphine (or in some formulations known as Krokodil) is a semi-synthetic opioid commercialized by Roche, with powerful, fast-acting effects, such as sedation and analgesia. It was first discovered and patented in Germany by a German team working for Knoll in 1920 but was not generally recognized. It was later synthesized in 1932 by American chemist Lyndon Frederick Small. Small also successfully patented it in 1934 in the United States. Desomorphine was used in Germany, Austria, and Switzerland under the brand name Permonid and was described as having a fast onset and a short duration of a
