Problems with overheating and unstable temperature of industrial equipment are the reasons for generating significant costs that companies. Solving problems related to heat removal is a challenge in modern industry. Phase change materials solution these challenges (PCM). These substances can accumulate release large amounts thermal energy during phase transition. The value transition enthalpy d...

Latent heat storage units for refrigeration processes are promising as alternatives to water/glycol-based due their significantly higher energy densities, which would lead more compact and potentially cost-effective storages. In this study, important thermophysical properties of five phase change material (PCM) candidates determined in the temperature range between ?22 ?35 °C compatibility with...

Here, a new platform for realization of novel nonvolatile optical switching devices was proposed that takes an advantage high field confinement provided by plasmonics and multi-state programming capabilities chalcogenide phase change materials. A reduction in the overall energy consumption consists enhancement plasmonic allow to lower energies implementation materials operate under zero-static ...

Increasing global temperature is alarming the need for construction industry to have thermally efficient building materials. Incorporating Phase Change Materials (PCM) in buildings widely accepted method reduction temperature, thereby achieving better thermal efficiency. This paper focuses on assessment of performance PCM-incorporated under tropical climatic condition. The simulation process wa...

Achieving homogeneous phase transition and uniform charge distribution is essential for good cycle stability and high capacity when phase conversion materials are used as electrodes. Herein, we show that chemical lithiation of bulk 2H-MoS2 distorts its crystalline domains in three primary directions to produce mosaic-like 1T' nanocrystalline domains, which improve phase and charge uniformity du...

Several chalcogenide alloys exhibit a pronounced contrast between the optical absorption in the metastable rocksalt and in the amorphous phase. This phenomenon is the basis for their application in optical data storage. Here we present ab initio calculations of the optical properties of GeTe and Ge1Sb2Te4 in the two phases. The analysis of our computations and experimental data reveal the corre...

Phase change materials (PCM) take advantage of latent heat that can be stored or released from a material over a narrow temperature range. PCM possesses the ability to change their state with a certain temperature range. These materials absorb energy during the heating process as phase change takes place and release energy to the environment in the phase change range during a reverse cooling pr...
