Transitional Phenomena on Phase Change Materials

An Algorithm based on Predicting the Interface in Phase Change Materials

Phase change materials are substances that absorb and release thermal energy during the process of melting and freezing. This characteristic makes phase change material (PCM)  a favourite choice to integrate it in buildings. Stephan problem including melting and solidification in PMC materials is an practical problem in many engineering processes. The position of the moving boundary, its veloci...

Recent Advances on Neuromorphic Systems Using Phase-Change Materials

Realization of brain-like computer has always been human's ultimate dream. Today, the possibility of having this dream come true has been significantly boosted due to the advent of several emerging non-volatile memory devices. Within these innovative technologies, phase-change memory device has been commonly regarded as the most promising candidate to imitate the biological brain, owing to its ...

Nano-Encapsulated Smart Tunable Phase Change Materials

Thermal Transport in Phase Change Memory Materials

Phase change memory uses brief pulses of electrical current to induce phase transitions in chalcogenide material regions with dimensions near or even far below 50 nm. The strongly differing electrical conductivities of the crystalline and amorphous phases allow data storage at densities in excess of terabits per square inch. Nanoscale conduction heat transfer governs the figures of merit in the...

Thermal Management Using “ Dry ” Phase Change Materials

The thermal response characteristic of a hybrid cooler that is charged with a “dry” solid-solid phase change compound is evaluated. A mathematical model that simulates the performance of a cooler/heat storage unit is formulated. A prototype heat sink that incorporates heat storage using a “dry” PCM is tested, and used to benchmark the simulation model. Different heating and cooling strategies a...
