Thermal energy storage (TES) systems using phase change materials (PCM) have been lately studied and are presented as one of the key solutions for the implementation of renewable energies. These systems take advantage of the latent heat of phase change of PCM during their melting/solidification processes to store or release heat depending on the needs and availability. Low thermal conductivity and latent heat are the main disadvantages of organic PCM, while corrosion, subcooling and thermal stability are the prime problems that inorganic PCM present...

Carbon nanotubes (CNTs) are attractive nanostructures in this regard, primarily due to their high aspect ratio coupled with high thermal and electrical conductivities. Consequently, CNT polymer composites have been extensively investigated for various applications, owing to their light weight and processibility. However, there have been several issues affecting the utilization of CNTs, such as aggregation (bundling) which leads to a non-uniform dispersion and poor interfacial bonding of the CNTs with the polymer, resulting in variation in composite performance, along with the additional issue of high cost of CNTs...

So-Won Choi, Tae-Ho Kim, Sang-Ho Cha
Vanadium redox flow batteries (VRFBs) have received considerable attention as large-scale electrochemical energy storage systems. In particular, VRFBs offer a higher power and energy density than other RFBs and mitigate undesirable performance fading, such as inevitable ion crossover, because of the unique advantage that only the vanadium ion is employed as the active species in the two electrolytes. The key constituent of VRFBs is a separator to conduct protons and prevent cross-mixing of the positive and negative electrolytes...

Lei Wang, Sidi Gong, Cihui Yang, Jing Wen
A theoretical model has been previously proposed to optimize the structure of the electrical probe memory system, whereby the optimal thickness and resistivity of DLC capping layer and TiN under layer are predicted to be 2 nm, 0.01 Ω× m, and 40 nm, 2×10-7 Ω× m, respectively. However, there is no experimental evidence to show that such a media stack can be fabricated in reality by the time of writing. In order to realize this optimized design experimentally, the thickness dependent resistivity for both DLC and TiN film are assessed, from which it is not possible to obtain a media stack with exactly the same properties as the optimized design...
