Polymer based phase change materials (PCM) for thermal energy storage (TES) applications have gained some attention recently due to their high stability and potential solid transition. Here, we are the first utilize a simple copolymerization strategy static tunability transition temperature (Tt) of polymeric PCM. The between short long side chain polyethylene glycol methacrylate polymers was de...

The paper presents an experimental setup developed for phase change materials (PCM) testing inside a vertical shell and tube heat exchanger (VSATHE). work presented part of more complex one focusing on designing PCM that could be used in the defrosting process commercial refrigeration systems. were paraffin RT54HC, while water was as transfer fluid (HTF). This impact changing temperature inlet ...

Nowadays, the energy consumption and production has considered as an interesting topic and debatable among researchers. The demand for generation of newer energy sources are increasing steadily day by day. This calls for design and development of novel energy saving devices in order to reduce the consumption of energy [1]. The enormous increase in production of greenhouse gases in atmosphere an...

The electron transport through ultra-scaled amorphous phase change material (PCM) GeTe is investigated by using ab initio molecular dynamics, density functional theory, and non-equilibrium Green’s function, and the inelastic electron–phonon scattering is accounted for by using the Born approximation. It is shown that, in ultra-scaled PCM device with 6 nm channel length, <4 % of the energy carri...

The global demand of the heating and cooling applications gives a larger potential to study thermal energy storage system. Phase change materials (PCM) that are used charge, store, discharge heat inferior in transfer characteristics. properties PCM can be improved by adding nanoparticles, changing orientation enclosure or both. Two-dimensional transient numerical analysis on effect Grashoff num...

Phase-change materials (PCMs) are promising candidates for nonvolatile data storage and reconfigurable electronics, but high programming currents have presented a challenge to realize low-power operation. We controlled PCM bits with single-wall and small-diameter multi-wall carbon nanotubes. This configuration achieves programming currents of 0.5 microampere (set) and 5 microamperes (reset), tw...

A new lightweight gas-particle mixture generator for fire-extinguishing purposes is designed such as to keep the generator and aerosol temperatures low by including a Phase Change Materials (PCM) component. The new generator performances have been studied experimentally and compared to the corresponding performances of a traditional design. The temperature evolution profiles of this gas-particl...

Chalcogenide Phase Change Materials (PCM) and metal insulator transition (MIT) materials are a group of that capable switching between low resistance high states. These emerging have been widely used in optical storage media memory devices. Over the past recent years, there interests exploiting PCM MIT materials, especially germanium antimony telluride (GST) alloys vanadium dioxide (VO <sub xml...
