  2. Sublimation (phase transition) - Wikipedia

    en.wikipedia.org/wiki/Sublimation_(phase_transition)

    In order to transfer the image from the paper to the substrate, it requires a heat press process that is a combination of time, temperature and pressure. The heat press applies this special combination, which can change depending on the substrate, to “transfer” the sublimation dyes at the molecular level into the substrate.

  3. Stefan problem - Wikipedia

    en.wikipedia.org/wiki/Stefan_problem

    The classical Stefan problem aims to describe the evolution of the boundary between two phases of a material undergoing a phase change, for example the melting of a solid, such as ice to water. This is accomplished by solving heat equations in both regions, subject to given boundary and initial conditions. At the interface between the phases ...

  4. Deposition (phase transition) - Wikipedia

    en.wikipedia.org/wiki/Deposition_(phase_transition)

    One example of deposition is the process by which, in sub-freezing air, water vapour changes directly to ice without first becoming a liquid. This is how frost and hoar frost form on the ground or other surfaces. Another example is when frost forms on a leaf. For deposition to occur, thermal energy must be removed from a gas.

  5. Freeze drying - Wikipedia

    en.wikipedia.org/wiki/Freeze_drying

    During the freezing stage, the material is cooled below its triple point, the temperature at which the solid, liquid, and gas phases of the material can coexist. This ensures that sublimation rather than melting will occur in the following steps. To facilitate faster and more efficient freeze drying, larger ice crystals are preferable.

  6. Close-space sublimation - Wikipedia

    en.wikipedia.org/wiki/Close-space_sublimation

    Closed space sublimation is a method of producing thin-films, esp. cadmium telluride photovoltaics, though it is used for other materials like antimony triselenide. [1] Diagram showing working principle of CSS. It is a type of physical vapor deposition where the substrate to be coated and the source material are held close to one another. They ...

  7. Ablation - Wikipedia

    en.wikipedia.org/wiki/Ablation

    Ablation refers to the melting of snow or ice that runs off the glacier, evaporation, sublimation, calving, or erosive removal of snow by wind. Air temperature is typically the dominant control of ablation, with precipitation exercising secondary control.

  8. Snowmelt - Wikipedia

    en.wikipedia.org/wiki/Snowmelt

    Generally the net longwave radiation term is negative, meaning a net loss of energy from the snowpack. Latent temperature flux is the energy removed from or delivered to the snowpack which accompanies the mass transfers of evaporation, sublimation, or condensation. Sensible heat flux is the heat flux due to convection between the air and snowpack.

  9. Heat transfer - Wikipedia

    en.wikipedia.org/wiki/Heat_transfer

    Phase change examples are the melting of ice or the boiling of water. The Mason equation explains the growth of a water droplet based on the effects of heat transport on evaporation and condensation. Phase transitions involve the four fundamental states of matter: Solid – Deposition, freezing, and solid-to-solid transformation.
