  2. Trap (plumbing) - Wikipedia

    en.wikipedia.org/wiki/Trap_(plumbing)

    In plumbing, a trap is a U-shaped portion of pipe designed to trap liquid or gas to prevent unwanted flow; most notably sewer gases from entering buildings while allowing waste materials to pass through. In oil refineries, traps are used to prevent hydrocarbons and other dangerous gases and chemical fumes from escaping through drains.

  3. Partition coefficient - Wikipedia

    en.wikipedia.org/wiki/Partition_coefficient

    The partition coefficient, abbreviated P, is defined as a particular ratio of the concentrations of a solute between the two solvents (a biphase of liquid phases), specifically for un-ionized solutes, and the logarithm of the ratio is thus log P.

  4. Petroleum trap - Wikipedia

    en.wikipedia.org/wiki/Structural_trap

    Anticlinal trap. An anticline is an area of the subsurface where the strata have been pushed into forming a domed shape. If there is a layer of impermeable rock present in this dome shape, then water-insoluble hydrocarbons can accumulate at the crest until the anticline is filled to the spill point (the highest point where hydrocarbons can escape the anticline).

  5. Petroleum geology - Wikipedia

    en.wikipedia.org/wiki/Petroleum_geology

    The use of geochemistry is relatively cost-effective that allows geologists to assess reservoir-related issues. Once oil to source rock correlation is found, petroleum geologists will use this information to render a 3D model of the basin. Now they can assess the timing of generation, migration, and accumulation relative to the trap formation.

  6. Chemical trap - Wikipedia

    en.wikipedia.org/wiki/Chemical_trap

    In chemistry, a chemical trap is a chemical compound that is used to detect unstable compounds. [1] The method relies on efficiency of bimolecular reactions with reagents to produce a more easily characterize trapped product. In some cases, the trapping agent is used in large excess.

  7. Quadrupole ion trap - Wikipedia

    en.wikipedia.org/wiki/Quadrupole_ion_trap

    In experimental physics, a quadrupole ion trap or paul trap is a type of ion trap that uses dynamic electric fields to trap charged particles. They are also called radio frequency (RF) traps or Paul traps in honor of Wolfgang Paul , who invented the device [ 1 ] [ 2 ] and shared the Nobel Prize in Physics in 1989 for this work. [ 3 ]

    Elizabeth's PTSD is much more prominent on the show than it is in the books. In both the book and the show, Elizabeth is raped by a professor at UCLA, which leads to her quiet dismissal from the ...

  9. Physical chemistry - Wikipedia

    en.wikipedia.org/wiki/Physical_chemistry

    Physical chemistry is the study of macroscopic and microscopic phenomena in chemical systems in terms of the principles, practices, and concepts of physics such as motion, energy, force, time, thermodynamics, quantum chemistry, statistical mechanics, analytical dynamics and chemical equilibria.
