Bumping is a phenomenon in chemistry where homogeneous liquids boiled in a test tube or other container will superheat and, upon nucleation, rapid boiling will expel the liquid from the container. In extreme cases, the container may be broken.
Sonication can be used for the production of nanoparticles, such as nanoemulsions, [5] nanocrystals, liposomes and wax emulsions, as well as for wastewater purification, degassing, extraction of seaweed polysaccharides [1] and plant oil, extraction of anthocyanins and antioxidants, [6] production of biofuels, crude oil desulphurization, cell disruption, polymer and epoxy processing, adhesive ...
The agitation is achieved by movement of the heterogeneous mass (liquid-solid phase). In mechanical agitators, this the result of the rotation of an impeller. The bulk can be composed of different substances and the aim of the operation is to blend it or to improve the efficiency of a reaction by a better contact between reactive product.
In biochemistry, denaturation is a process in which proteins or nucleic acids lose folded structure present in their native state due to various factors, including application of some external stress or compound, such as a strong acid or base, a concentrated inorganic salt, an organic solvent (e.g., alcohol or chloroform), agitation and radiation, or heat.

Chlorpromazine, an antipsychotic and antiemetic drug which is classed as a "major" tranquilizer, may cause paradoxical effects such as agitation, hallucinations, excitement, insomnia, bizarre dreams, aggravation of psychotic symptoms and toxic confusional states. [8] These may be more common in elderly dementia patients.
In the simplest example of the method, an equal volume of beads are added to a cell or tissue suspension in a test tube and the sample is vigorously mixed on a common laboratory vortex mixer. While processing times are slow, taking 3–10 times longer than that in specialty shaking machines , it works well for easily disrupted cells and is ...

Cathinone (/ ˈ k æ θ ɪ n oʊ n /; also known as benzoylethanamine, or β-keto-amphetamine) is a monoamine alkaloid found in the shrub Catha edulis and is chemically similar to ephedrine, cathine, methcathinone and other amphetamines.
