  2. Carbon fibers - Wikipedia

    en.wikipedia.org/wiki/Carbon_fibers

    Carbon fibers or carbon fibres (alternatively CF, graphite fiber or graphite fibre) are fibers about 5 to 10 micrometers (0.00020–0.00039 in) in diameter and composed mostly of carbon atoms. [1] Carbon fibers have several advantages: high stiffness, high tensile strength, high strength to weight ratio, high chemical resistance, high ...

  3. Photophosphorylation - Wikipedia

    en.wikipedia.org/wiki/Photophosphorylation

    In photophosphorylation, light energy is used to pump protons across a biological membrane, mediated by flow of electrons through an electron transport chain. This stores energy in a proton gradient. As the protons flow back through an enzyme called ATP synthase, ATP is generated from ADP and inorganic phosphate.

  4. Electron density - Wikipedia

    en.wikipedia.org/wiki/Electron_density

    In quantum chemical calculations, the electron density, ρ(r), is a function of the coordinates r, defined so ρ(r)dr is the number of electrons in a small volume dr. For closed-shell molecules, ρ ( r ) {\displaystyle \rho (\mathbf {r} )} can be written in terms of a sum of products of basis functions, φ:

    The following high-fiber foods are "good" sources of fiber, meaning they contain more than 10% but less than 20% of your daily recommended fiber intake. 17. Pears

  6. Carbon - Wikipedia

    en.wikipedia.org/wiki/Carbon

    Carbon-carbon bonds are strong and stable. Through catenation, carbon forms a countless number of compounds. A tally of unique compounds shows that more contain carbon than do not. [88] A similar claim can be made for hydrogen because most organic compounds contain hydrogen chemically bonded to carbon or another common element like oxygen or ...

  8. Energy level - Wikipedia

    en.wikipedia.org/wiki/Energy_level

    Each shell can contain only a fixed number of electrons: The first shell can hold up to two electrons, the second shell can hold up to eight (2 + 6) electrons, the third shell can hold up to 18 (2 + 6 + 10) and so on. The general formula is that the nth shell can in principle hold up to 2n 2 electrons. [1]
