  • n. A flourlike food preparation made from skim milk, and consisting essentially of the unaltered proteid of milk. It is also used in making biscuits and crackers, for mixing with cocoa, etc. A mixture of this with butter, water, and salt is called Plasmon butter, and resembles clotted cream in appearance.

Etymologies

Examples

  • Ordinarily, visible-light lasers cannot be narrower than the wavelength of the light being used, but researchers have found ways around that fundamental limit by using a virtual particle called a plasmon, which is like a wave passing through a cloud of electrons.

  • The colours were produced by a process known as plasmon resonance in a patterned aluminium film made in the university's James Watt Nanofabrication Centre.

    BBC News - Home

  • The team, led by Professor David Cumming and Dr Tim Drysdale from the University's department of electronics and electrical engineering, will take advantage of a phenomenon called plasmon resonance in their efforts to create a microchip for cameras and other imaging equipment that will produce sharper, more colourful images.

  • Fundamentally, a plasmon is a quasiparticle, a quantum of a plasma oscillation, as much as a photon is a quantization of light.

  • A plasmon is a collective excitation of the electronic "fluid" in a piece of conducting material, like ripples on the surface of a pond are a collective mode of the water molecules of the liquid.

    nanoscale views

  • The semiconductor, called a plasmon, can focus light the size of a single protein in a space that is smaller than half its wavelength while maintaining laser-like qualities that allow it to not dissipate over time.

    Nano Tech Wire

  • In physics jargon, a "plasmon" is the quasiparticle resulting from the quantization of plasma oscillation; it's essentially the collective oscillations of the free electron gas at a metallic surface, often at optical frequencies.

  • Nanoscale patterns of nanoparticles have the potential to be used in miniature electronic circuits or in plasmon waveguides to guide the transport of electromagnetic energy below the diffraction limit.
