Sonication A sonicator at the Weizmann Institute of Science during sonication. Sonication is the act of applying sound energy to agitate particles in a sample, for various purposes. Ultrasonic frequencies (>20 kHz) are usually used, leading to the process also being known as ultrasonication or ultra-sonication. In the laboratory, it is usually applied using an ultrasonic bath or an ultrasonic probe, colloquially known as a sonicator.

Assonance Alliteration: Alliteration is a special case of consonance and refers to the repetition of consonant sounds or blends at the beginning of words or in the stressed syllables of a line. Since consonance may happen anywhere in a word, the concepts are related but not identical.

Phonation Phonation. The process of speech production by the human voice may be divided into phonation, resonation, and articulation. Phonation is the process by which energy from the lungs in the form of air pressure is converted into audible vibrations.One method of phonation involves using the air pressure to set the elastic vocal folds into vibration, a process called voicing.honation is the process by which energy from the lungs in the form of air pressure is converted into audible vibrations.

Alliteration Definition of Alliteration. Alliteration is the repetition of the same consonant sounds at the beginning of words that are in close proximity to each other. This repetition of sounds brings attention to the lines in which it is used, and creates more aural rhythm.

Hydrogenation Hydrogenation – to treat with hydrogen – is a chemical reaction between molecular hydrogen (H2) and another compound or element, usually in the presence of a catalyst such as nickel, palladium or platinum. The process is commonly employed to reduce or saturate organic compounds. Hydrogenation typically constitutes the addition of pairs of hydrogen atoms to a molecule, often an alkene. Catalysts are required for the reaction to be usable; non-catalytic hydrogenation takes place only at very high temperatures.

- dilation is a transformation (notation) that produces an image that is the same shape as the original, but is a different size. A dilation stretches or shrinks the original figure. The description of a dilation includes the scale factor (or ratio) and the center of the dilation.The center of dilation is a fixed point in the plane about which all points are expanded or contracted. It is the only invariant point under a dilation.A dilation of scalar factor k whose center of dilation is the origin may be written: Dk (x, y) = (kx, ky). If the scale factor, k, is greater than 1, the image is an enlargement (a stretch). If the scale factor is between 0 and 1, the image is a reduction (a shrink). dilation of scalar factor k whose center of dilation is the origin may be written: Dk (x, y) = (kx, ky). If the scale factor, k, is greater than 1, the image is an enlargement (a stretch).

Methylation In the chemical sciences, methylation denotes the addition of a methyl group to a substrate or the substitution of an atom or group by a methyl group.Methylation is a form of alkylation with a methyl group, rather than a larger carbon chain, replacing a hydrogen atom.NA methylation in vertebrates typically occurs at CpG sites (cytosine-phosphate-guanine sites, that is, where a cytosine is directly followed by a guanine in the DNA sequence).
