Phase Changing Materials in Buildings

International Journal of Sustainable Building Technology and Urban Development, 2011
New 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.

Phase Change Materials

2020
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, 2012
Phase 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, 2011
Fire-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, 2012
AbstractEpitaxial $ {\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, 2011
ABSTRACTIon 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.

A map for phase-change materials

Nature Materials, 2008
Phase-change materials are characterized by a unique property portfolio well suited for data storage applications. Here, a first treasure map for phase-change materials is presented on the basis of a fundamental understanding of the bonding characteristics.

Atomic migration in phase change materials

2013 IEEE International Electron Devices Meeting, 2013
During 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.
