  2. Multipass spectroscopic absorption cells - Wikipedia

    en.wikipedia.org/wiki/Multipass_spectroscopic...

    This cell is also commonly used and has some advantages [4] over the White cell: It is simpler than the White cell with only two mirrors that are easier to position and less susceptible to mechanical disturbance of the cell; Can be more stable than the White cell; However, the Herriot cell does not accept high numerical aperture beams.

  3. Evolution of cells - Wikipedia

    en.wikipedia.org/wiki/Evolution_of_cells

    The eukaryotic cell seems to have evolved from a symbiotic community of prokaryotic cells. DNA-bearing organelles like mitochondria and chloroplasts are remnants of ancient symbiotic oxygen-breathing bacteria and cyanobacteria, respectively, where at least part of the rest of the cell may have been derived from an ancestral archaean prokaryote ...

  4. Cell engineering - Wikipedia

    en.wikipedia.org/wiki/Cell_engineering

    Cells engineered to fluoresce under UV light. Cell engineering is the purposeful process of adding, deleting, or modifying genetic sequences in living cells to achieve biological engineering goals such as altering cell production, changing cell growth and proliferation requirements, adding or removing cell functions, and many more.

  5. Wigner–Seitz cell - Wikipedia

    en.wikipedia.org/wiki/Wigner–Seitz_cell

    The general mathematical concept embodied in a Wigner–Seitz cell is more commonly called a Voronoi cell, and the partition of the plane into these cells for a given set of point sites is known as a Voronoi diagram. The construction process for the Wigner–Seitz cell of a hexagonal lattice. The cell may be chosen by first picking a lattice ...

  6. Cell fusion - Wikipedia

    en.wikipedia.org/wiki/Cell_fusion

    Cell fusion is an important cellular process in which several uninucleate cells (cells with a single nucleus) combine to form a multinucleate cell, known as a syncytium. Cell fusion occurs during differentiation of myoblasts , osteoclasts and trophoblasts , during embryogenesis , and morphogenesis . [ 1 ]

  7. Bleb (cell biology) - Wikipedia

    en.wikipedia.org/wiki/Bleb_(cell_biology)

    Bleb growth is driven by intracellular pressure (abnormal growth) generated in the cytoplasm when the actin cortex undergoes actomyosin contractions. [5] The disruption of the membrane-actin cortex interactions [4] are dependent on the activity of myosin-ATPase [6] Bleb initiation is affected by three main factors: high intracellular pressure, decreased amounts of cortex-membrane linker ...

  8. Human Cell Atlas - Wikipedia

    en.wikipedia.org/wiki/Human_Cell_Atlas

    The Human Cell Atlas is a global project to describe all cell types in the human body. [1] The initiative was announced by a consortium after its inaugural meeting in London in October 2016, which established the first phase of the project.

  9. Pockels effect - Wikipedia

    en.wikipedia.org/wiki/Pockels_effect

    Pockels cell drivers provide this high voltage in the form of very fast pulses, which typically have rise times of less than 10 nanoseconds. There are basically two types of drivers: a quick or Q drive which has a fast rise time, then slowly decays. A Pockels cell that uses a Q-drive is sometimes referred to as a Q-switch.
