  2. Self-phase modulation - Wikipedia

    en.wikipedia.org/wiki/Self-phase_modulation

    Self-phase modulation (SPM) is a nonlinear optical effect of light–matter interaction. An ultrashort pulse of light, when travelling in a medium, will induce a varying refractive index of the medium due to the optical Kerr effect. [1]

  5. Scanning probe microscopy - Wikipedia

    en.wikipedia.org/wiki/Scanning_probe_microscopy

    Scanning probe microscopy (SPM) is a branch of microscopy that forms images of surfaces using a physical probe that scans the specimen. SPM was founded in 1981, with the invention of the scanning tunneling microscope , an instrument for imaging surfaces at the atomic level.

    en.wikipedia.org/wiki/Specialized_pro-resolving...

    The production and activities of the SPM suggest a new view of inflammation wherein the initial response to foreign organisms, tissue injury, or other insults involves numerous soluble cell signaling molecules that not only recruit various cell types to promote inflammation but concurrently cause these cells to produce SPM which feed back on their parent and other cells to dampen their pro ...

  7. Atomic force microscopy - Wikipedia

    en.wikipedia.org/wiki/Atomic_force_microscopy

    Atomic force microscopy [1] (AFM) is a type of SPM, with demonstrated resolution on the order of fractions of a nanometer, more than 1000 times better than the optical diffraction limit. The information is gathered by "feeling" or "touching" the surface with a mechanical probe.

  8. Scanning probe lithography - Wikipedia

    en.wikipedia.org/wiki/Scanning_probe_lithography

    Scanning probe lithography [1] (SPL) describes a set of nanolithographic methods to pattern material on the nanoscale using scanning probes. It is a direct-write, mask-less approach which bypasses the diffraction limit and can reach resolutions below 10 nm. [2]

  9. Permanent magnet motor - Wikipedia

    en.wikipedia.org/wiki/Permanent_magnet_motor

    Permanent magnet motors consist of two main types. Surface permanent magnet motors (SPM) and internal permanent magnet (IPM) motors. The main difference is that SPM motors place the magnets on the outside of the rotor while IPM motors place their magnets inside the motor. Benefits to internal magnets include structural integrity and reducing ...
