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 ...
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 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 .

Give minimum and maximum values if there's a range. Fat content: Total percentage, by weight. Give ...
Dispersion results from two processes: convection due to the flow of the carrier stream and diffusion due to a concentration gradient between the sample and the carrier stream. Convection of the sample occurs by laminar flow, in which the linear velocity of the sample at the tube's walls is zero, while the sample at the center of the tube moves ...
Tracers are used in the oil industry in order to qualitatively or quantitatively gauge how fluid flows through the reservoir, [1] as well as being a useful tool for estimating residual oil saturation. Tracers can be used in either interwell tests or single well tests. [2]
These are properties that make naphthenic oils particularly useful for the speciality oil market: 1. Transformer oils. Naphthenic oils have excellent cooling and insulating properties because of a low viscosity index. The good solubility of the oils is also important for enhanced compatibility with seals and gaskets, for example. 2. Process oils.
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 ...
