  2. Sodium naphthalene - Wikipedia

    en.wikipedia.org/wiki/Sodium_naphthalene

    Sodium naphthalene is an organic salt with the chemical formula Na + [C 10 H 8] −. In the research laboratory, it is used as a reductant in the synthesis of organic, organometallic, and inorganic chemistry. It is usually generated in situ. When isolated, it invariably crystallizes as a solvate with ligands bound to Na +. [1]

  3. Surface treatment of PTFE - Wikipedia

    en.wikipedia.org/wiki/Surface_treatment_of_PTFE

    Virtually all sodium etching bond strengths reported in academic journals predate the advent of glymes as carriers for sodium naphthalene complex. In adhesion tests per ASTM D4541, in which an aluminum stud is bonded to the test surface and the stud is pulled in the direction normal to the surface, both surfaces of the failure interface were ...

  4. Small-angle X-ray scattering - Wikipedia

    en.wikipedia.org/wiki/Small-angle_X-ray_scattering

    Small-angle X-ray scattering (SAXS) is a small-angle scattering technique by which nanoscale density differences in a sample can be quantified. This means that it can determine nanoparticle size distributions, resolve the size and shape of (monodisperse) macromolecules, determine pore sizes and characteristic distances of partially ordered materials. [1]

  5. X-ray fluorescence - Wikipedia

    en.wikipedia.org/wiki/X-ray_fluorescence

    William Lawrence Bragg proposed a model in which the incoming X-rays are scattered specularly (mirror-like) from each plane; from that assumption, X-rays scattered from adjacent planes will combine constructively (constructive interference) when the angle θ between the plane and the X-ray results in a path-length difference that is an integer ...

  6. X-ray crystallography - Wikipedia

    en.wikipedia.org/wiki/X-ray_crystallography

    A powder X-ray diffractometer in motion. X-ray crystallography is the experimental science of determining the atomic and molecular structure of a crystal, in which the crystalline structure causes a beam of incident X-rays to diffract in specific directions.

  7. Anionic addition polymerization - Wikipedia

    en.wikipedia.org/wiki/Anionic_addition...

    [5] [6] In one of the breakthrough events in the field of polymer science, Szwarc elucidated that electron transfer occurred from radical anion sodium naphthalene to styrene. The results in the formation of an organosodium species, which rapidly added styrene to form a "two – ended living polymer."

  8. Energy-dispersive X-ray spectroscopy - Wikipedia

    en.wikipedia.org/wiki/Energy-dispersive_X-ray...

    Energy-dispersive X-ray spectroscopy (EDS, EDX, EDXS or XEDS), sometimes called energy dispersive X-ray analysis (EDXA or EDAX) or energy dispersive X-ray microanalysis (EDXMA), is an analytical technique used for the elemental analysis or chemical characterization of a sample. It relies on an interaction of some source of X-ray excitation and ...

  9. Naphthalene - Wikipedia

    en.wikipedia.org/wiki/Naphthalene

    With alkali metals, naphthalene forms the dark blue-green radical anion salts such as sodium naphthalene, Na + C 10 H − 8. The naphthalene anions are strong reducing agents. Naphthalene can be hydrogenated under high pressure in the presence of metal catalysts to give 1,2,3,4-tetrahydronaphthalene(C 10 H 12), also known as tetralin.
