“…In a recent review, Al-Kayiem et al [99] discussed the application of nanoenhanced PCMs for heating and cooling of buildings through enhancing the thermal storage capacity. Based on the thermo-physical characterization of polyethylene glycols mixed with epoxy resin and aluminum powder by using DSC measurements, Constantinescu et al [100] concluded that this nano composite is suitable for building applications due to its large latent heat, appropriate phase change temperature and good stability.…”

Nano-enhanced phase change materials (PCMs) have attracted increasing attention to address one of the key barriers (i.e. low thermal conductivity) to the wide adoption of PCMs in many industrial applications. This paper discusses the generic problem and key issues associated with appropriately using this new class of materials in buildings for effective thermal management and improved energy performance. An overview on major recent development and application of nano-enhanced PCMs as thermal energy storage media is provided. A case study based on a PCM ceiling ventilation system integrated with solar photovoltaic thermal (PVT) collectors is then performed to evaluate the potential benefits due to the dispersion of copper nanoparticles into the PCM base fluid of RT24. The results showed that this nano-enhanced PCM has higher melting and solidification rates than that of the pure PCM. Compared to the use of the pure PCM, 8.3% more heat was charged in and 25.1% more heat was discharged from the nano-enhanced PCM under the three winter test days. More research is needed to understand the fundamental mechanisms behind the PCM thermal conductivity enhancement through the dispersion of nanometer-sized materials and to investigate how these mechanisms drive building performance enhancement.

In another stability study on microtabular SOFC [155], excellent stability with a minor degradation rate of 0.25% in 100 h operations at 200 mA and 0.75 V was obtained using NiO-Gd doped ceria (GDC), GDC, and La 0.6 Sr 0.4 Co 0.2 Fe 0.8 O 3 − ı -GDC as anode, electrolyte and cathode, respectively.…”

“…This leads to reduced charging/discharging power, exit temperature and usable heat capacity, and may result in expensive storage heat exchangers. The utilization of nanomaterials in thermal energy storage technologies become more and more important as a radical solution for improving the performances of thermal systems and overcoming the aforementioned problems of heat transfer [3]. Enhanced thermal transfer properties are the result of very large specific surface area brought by the utilization of nanosystems.…”
