Fire retardants for phase change materials
Applied Energy, 2011Fire-retarded form-stable phase change material (PCM) products consisting of paraffin (RT21) (or propyl ester), high density polyethylene (HDPE) and fire retardants were prepared using the Brabender Plastograph. The properties of the form-stable PCM, containing different types of fire retardants such as magnesium hydroxide, aluminium hydroxide ...

Annual Review of Materials Research, 2009
Phase change materials (PCMs) can exist in at least two different phases (an amorphous and one or more crystalline phases), and they can be switched repeatedly between these phases. The different phases have distinctly different physical properties such as electrical conductivity, optical reflectivity, mass density, or thermal conductivity.

The world’s rapid increase of energy consumption and demand with the environmental bad effects of fossil and traditional fuels prompted scientists and researchers to search for methods of storing and reducing energy consumption. Phase change materials (PCMs) are substances that have the ability to store and release energy at constant temperature during

Nanoscale phase change memory materials
Nanoscale, 2012Phase change memory materials store information through their reversible transitions between crystalline and amorphous states. For typical metal chalcogenide compounds, their phase transition properties directly impact critical memory characteristics and the manipulation of these is a major focus in the field. Here, we discuss recent work that explores

Ion Irradiation on Phase Change Materials
MRS Proceedings, 2011ABSTRACTIon irradiation with 130 keV Ge+ or 120 keV Sb+ has modified, by thermal spike effect, the local atomic arrangement in the structure of as-deposited sputtered amorphous GeTe and Ge2Sb2Te5 thin films. The changes in the local order have been analyzed by Raman and EXAFS spectroscopy.

Tuning Metasurfaces with Phase Change Materials
2019 21st International Conference on Transparent Optical Networks (ICTON), 2019The possibility to reversibly modify the optical properties of plasmonic nanorod arrays by phase change materials is investigated. Three different gold (Au) nanorod arrays are fabricated on thin films of vanadium dioxide. The sensitivity of the two nanorod plasmonic modes to the thermally induced phase transition is explored and found to be greatest ...

Atomic migration in phase change materials
2013 IEEE International Electron Devices Meeting, 2013During normal operation of Phase Change Memory (PCM) cells active materials undergo very high electrical and thermal stresses that cause a motion of the different atoms leading to composition variation which has a fundamental impact on performance and reliability.
