  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. 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.

  4. Crossbow - Wikipedia

    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.

  5. 9.3×62mm - Wikipedia

    en.wikipedia.org/wiki/9.3×62mm

    The 9.3×74mmR is a rimmed cartridge that evolved from the 9.3×72mmR black powder cartridge. The energy levels of the 9.3×62mm and 9.3×74mmR cartridges are similar, but the cartridges are unrelated. The rimmed cartridge is slightly longer than the 9.3x62mm, allowing for lower pressure in the case while retaining muzzle velocity and energy.

  6. Polysorbate 80 - Wikipedia

    en.wikipedia.org/wiki/Polysorbate_80

    Polysorbate 80 is a surfactant and solubilizer used in a variety of oral and topical pharmaceutical products.. Polysorbate 80 is also an excipient that is used to stabilize aqueous formulations of medications for parenteral administration, and used as an emulsifier in the making of the antiarrhythmic amiodarone. [9]

  7. Critical micelle concentration - Wikipedia

    en.wikipedia.org/wiki/Critical_micelle_concentration

    [7] [8] [9] These fit functions are based on a model for the concentrations of monomeric and micellised surfactants in solution, which establishes a well-defined analytical definition of the CMC, independent from the technique. The CMC is the concentration of surfactants in the bulk at which micelles start forming.

  8. Bullet-shooting crossbow - Wikipedia

    en.wikipedia.org/wiki/Bullet-shooting_crossbow

    Because the standard bolt does more damage, the bullet-shooting crossbow was reserved for hunting smaller animals. There was no reason to use a bolt-shooting crossbow to hunt squirrels when a smaller, less-powerful weapon could get the job done just as effectively. Another flaw lies in the material of choice: steel.

  9. Biosurfactant - Wikipedia

    en.wikipedia.org/wiki/Biosurfactant

    Like synthetic surfactants, they are composed of a hydrophilic moiety made up of amino acids, peptides, (poly)saccharides, or sugar alcohols and a hydrophobic moiety consisting of fatty acids. Correspondingly, the significant classes of biosurfactants include glycolipids , lipopeptides and lipoproteins, and polymeric surfactants as well as ...
