  2. Surfactin - Wikipedia

    en.wikipedia.org/wiki/Surfactin

    Surfactin is a cyclic lipopeptide, commonly used as an antibiotic for its capacity as a surfactant. [2] It is an amphiphile capable of withstanding hydrophilic and hydrophobic environments. The Gram-positive bacterial species Bacillus subtilis produces surfactin for its antibiotic effects against competitors. [3]

  3. Triton X-100 - Wikipedia

    en.wikipedia.org/wiki/Triton_X-100

    Triton X--100 (C 14 H 22 O(C 2 H 4 O) n) is a nonionic surfactant that has a hydrophilic polyethylene oxide chain (on average it has 9.5 ethylene oxide units) and an aromatic hydrocarbon lipophilic or hydrophobic group. The hydrocarbon group is a 4-(1,1,3,3-tetramethylbutyl)-phenyl group.

    en.wikipedia.org/wiki/Crossbow

    21st-century hunting compound crossbow. A crossbow is a ranged weapon using an elastic launching device consisting of a bow-like assembly called a prod, mounted horizontally on a main frame called a tiller, which is hand-held in a similar fashion to the stock of a long gun. Crossbows shoot arrow-like projectiles called bolts or quarrels.

  6. Sample preparation in mass spectrometry - Wikipedia

    en.wikipedia.org/wiki/Sample_preparation_in_mass...

    Sample preparation for mass spectrometry is used for the optimization of a sample for analysis in a mass spectrometer (MS). Each ionization method has certain factors that must be considered for that method to be successful, such as volume, concentration, sample phase, and composition of the analyte solution.

  7. Interfacial rheology - Wikipedia

    en.wikipedia.org/wiki/Interfacial_rheology

    Typical measurements include performing a frequency sweep for the solution to study the kinetics of the surfactant. In another measurement method suitable especially for insoluble surfactants, a Langmuir trough is used in an oscillating barrier mode. In this case, two barriers that limit the interfacial area are being oscillated sinusoidally ...

  8. Polysorbate 20 - Wikipedia

    en.wikipedia.org/wiki/Polysorbate_20

    Polysorbate 20 (common commercial brand names include Kolliphor PS 20, [2] Scattics, Alkest TW 20, Tween 20, and Kotilen-20) is a polysorbate-type nonionic surfactant formed by the ethoxylation of sorbitan monolaurate.
