  2. Phase-change material - Wikipedia

    en.wikipedia.org/wiki/Phase-change_material

    Thermal conductivity is a common property targeted for maximization by creating thermal composites. In this case, the basic idea is to increase thermal conductivity by adding a highly conducting solid (such as the copper mesh or graphite [25]) into the relatively low-conducting PCM, thus increasing overall or bulk (thermal) conductivity. [26]

  3. Phase-change memory - Wikipedia

    en.wikipedia.org/wiki/Phase-change_memory

    In the 1960s, Stanford R. Ovshinsky of Energy Conversion Devices first explored the properties of chalcogenide glasses as a potential memory technology. In 1969, Charles Sie published a dissertation at Iowa State University that both described and demonstrated the feasibility of a phase-change-memory device by integrating chalcogenide film with ...

  4. Computational Fluid Dynamics for Phase Change Materials

    en.wikipedia.org/wiki/Computational_Fluid...

    Computational Fluid Dynamics (CFD) modeling and simulation for phase change materials (PCMs) is a technique used to analyze the performance and behavior of PCMs. The CFD models have been successful in studying and analyzing the air quality, natural ventilation and stratified ventilation, air flow initiated by buoyancy forces and temperature space for the systems integrated with PCMs.

    Phase diagram of the GeSbTe ternary alloy system. GeSbTe is a ternary compound of germanium, antimony, and tellurium, with composition GeTe-Sb 2 Te 3.In the GeSbTe system, there is a pseudo-line as shown upon which most of the alloys lie.

  6. Resistive random-access memory - Wikipedia

    en.wikipedia.org/wiki/Resistive_random-access_memory

    ReRAM bears some similarities to conductive-bridging RAM (CBRAM) and phase-change memory (PCM) in that they change dielectric material properties. CBRAM involves one electrode providing ions that dissolve readily in an electrolyte material, while PCM involves generating sufficient Joule heating to effect amorphous-to-crystalline or crystalline ...

  7. Icosane - Wikipedia

    en.wikipedia.org/wiki/Icosane

    Icosane's phase transition at a moderate temperature makes it a candidate phase change material, or PCM which can be used to store thermal energy and control temperature. It can be detected in the body odor of persons suffering from Parkinson's disease .

  8. Polarizable continuum model - Wikipedia

    en.wikipedia.org/wiki/Polarizable_continuum_model

    The polarizable continuum model (PCM) is a commonly used method in computational chemistry to model solvation effects. If it is necessary to consider each solvent molecule as a separate molecule, the computational cost of modeling a solvent-mediated chemical reaction would grow prohibitively high.

  9. Pulse-code modulation - Wikipedia

    en.wikipedia.org/wiki/Pulse-code_modulation

    A PCM stream has two basic properties that determine the stream's fidelity to the original analog signal: the sampling rate, which is the number of times per second that samples are taken; and the bit depth, which determines the number of possible digital values that can be used to represent each sample.
