Organic phase change material (PCM) with macro-encapsulation is attractive in energy storage applications as it has relatively low cost. This study focuses on using PET plastic pipes to encapsulate paraffin and using low-cost float stones to increase the thermal conductivity of PCM modules as they have a special structure of high porosity. Float stones were immersed in the liquid PCM and an ult...

We describe a self-referencing interferometer in which the wavefront and its complex conjugate are generated in a Fabry-Perot cavity having one phase conjugate mirror (PCM). The finite response time of the PCM allows one to display momentarily the moiré between old and new interferograms after a sudden change has affected the input wavefront. Results using an externally pumped BaTiO(3) crystal ...

The accuracy of differential scanning calorimetry (DSC) used in the dynamic method, which is method most widely to measure thermal performance existing phase-change materials (PCMs), limited when measuring range and peak temperature PCMs combined with building materials. Therefore, we measured a thermochamber; samples were sheet shape-stabilized material (SSPCM) microencapsulated PCM-impregnate...

The current mainstream, based on the Flash technology, is expected to be the reference technology also for the next few years. Nevertheless Flash has technological and physical constraints that make more difficult their further scaling. In this contest there is the industrial interest for alternative technologies that exploit new materials and concepts to go beyond the Flash technology, to allo...

A central issue of nanoelectronics concerns their fundamental scaling limits, that is, the smallest and most energy-efficient devices that can function reliably. Unlike charge-based electronics that are prone to leakage at nanoscale dimensions, memory devices based on phase change materials (PCMs) are more scalable, storing digital information as the crystalline or amorphous state of a material...
