Carrier oil, also known as base oil or vegetable oil, is used to dilute essential oils and absolutes before they are applied to the skin in massage and aromatherapy. They are so named because they carry the essential oil onto the skin at a safe concentration. [1] Diluting essential oils is a critical safety practice when using essential oils.
This intraband absorption is different from interband absorption because the excited carrier is already in an excited band, such as an electron in the conduction band or a hole in the valence band, where it is free to move. In interband absorption, the carrier starts in a fixed, nonconducting band and is excited to a conducting one. In the ...
This template tabulates data of composition of various vegetable oils, their processing treatments (whether unrefined, hydrogenated or partially hydrogenated) and their smoke point The above documentation is transcluded from Template:Vegetable oils comparison/doc .

The chemical profiles, or crude oil assays, specify important properties such as the oil's API gravity. The delivery locations are usually sea ports close to the oil fields from which the crude was obtained (and new fields are constantly being explored), and the pricing is usually quoted based on FOB ( free on board , without consideration of ...
where p A is the partial pressure of A over the surface, [S] is the concentration of free sites in number/m 2, [A ad] is the surface concentration of A in molecules/m 2 (concentration of occupied sites), and k ad and k d are constants of forward adsorption reaction and backward desorption reaction in the above reactions.
A magnetorheological fluid (MR fluid, or MRF) is a type of smart fluid in a carrier fluid, usually a type of oil. When subjected to a magnetic field, the fluid greatly increases its apparent viscosity, to the point of becoming a viscoelastic solid. [1]
For example, doping pure silicon with a small amount of phosphorus will increase the carrier density of electrons, n. Then, since n > p, the doped silicon will be a n-type extrinsic semiconductor. Doping pure silicon with a small amount of boron will increase the carrier density of holes, so then p > n, and it will be a p-type extrinsic ...
