  • Amphiphile
    Amphiphile (from the Greek αμφις, amphis: both and φιλíα, philia: love, friendship) is a term describing a chemical compound possessing both hydrophilic (water-loving, polar) and lipophilic (fat-loving) properties.
  • Micelle
    A micelle (/maɪˈsɛl/) or micella (/maɪˈsɛlə/) (plural micelles or micellae, respectively) is an aggregate (or supramolecular assembly) of surfactant molecules dispersed in a liquid colloid.
  • Adsorption
    Adsorption is the adhesion of atoms, ions, or molecules from a gas, liquid, or dissolved solid to a surface.
  • Brownian motion
    Brownian motion or pedesis (from Ancient Greek: πήδησις /pέːdεːsis/ "leaping") is the random motion of particles suspended in a fluid (a liquid or a gas) resulting from their collision with the fast-moving atoms or molecules in the gas or liquid.
  • Emulsion
    An emulsion is a mixture of two or more liquids that are normally immiscible (unmixable or unblendable).
  • Solution
    In chemistry, a solution is a homogeneous mixture composed of two or more substances.
  • Suspension (chemistry)
    In chemistry, a suspension is a heterogeneous mixture containing solid particles that are sufficiently large for sedimentation.
  • Viscosity
    The viscosity of a fluid is a measure of its resistance to gradual deformation by shear stress or tensile stress.
  • Gel
    A gel is a solid jelly-like material that can have properties ranging from soft and weak to hard and tough.
  • Tyndall effect
    The Tyndall effect, also known as Tyndall scattering, is light scattering by particles in a colloid or else particles in a very fine suspension.
  • Colloidal gold
    Colloidal gold is a sol or colloidal suspension of submicrometre-size nanoparticles of gold in a fluid, usually water.
  • Sedimentation
    Sedimentation is the tendency for particles in suspension to settle out of the fluid in which they are entrained and come to rest against a barrier.
  • Interface and colloid science
    Interface and colloid science is an interdisciplinary intersection of branches of chemistry, physics, nanoscience and other fields dealing with colloids, heterogeneous systems consisting of a mechanical mixture of particles between 1 nm and 1000 nm dispersed in a continuous medium.
  • Mycosubtilin
    Mycosubtilin is a natural lipopeptide with antifungal and hemolytic activities and isolated from Bacillus species.
  • Surfactin
    Surfactin is a very powerful surfactant commonly used as an antibiotic.
  • Zeta potential
    Zeta potential is a scientific term for electrokinetic potential in colloidal dispersions.
  • Thermodynamics of micellization
    The surfactant’s critical micelle concentration (CMC) plays a factor in Gibbs free energy of micellization.
  • Ammonium perfluorononanoate
    Ammonium perfluorononanoate (APFN) is an anionic surfactant that in water forms liquid crystalline phases (Lyotropic liquid crystal).
