Organic Phase Change Materials
2022Thermal energy storage in the form of latent heat is important for efficient energy conservation and deployment. In recent years, numerous studies have been performed to develop improved phase change materials for thermal energy storage. Among them, organic materials have attracted particular attention owing to their safety, chemical stability and ...

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.

Phase Changing Materials in Buildings
International Journal of Sustainable Building Technology and Urban Development, 2011New technologies are needed in structures and services in order to reduce the great energy consumption of buildings. A major share of the energy demand is used for controlling the indoor climate. The requirements are only growing due to tightening regulation and increasing comfort expectations of the users.

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

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 ...

Epitaxial phase‐change materials
physica status solidi (RRL) – Rapid Research Letters, 2012AbstractEpitaxial $ {\rm Ge}_{2} {\rm Sb}_{2} {\rm Te}_{5} $ thin layers were successfully grown in the metastable cubic phase on both slightly lattice‐mismatched (GaSb) and highly lattice‐mismatched (Si) templates. The higher quality of the films grown on (111)‐oriented substrates is attributed to the tendency to form layered structures in the stable ...

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.
