We present a novel approach to reduce the thermal conductivity ($\kappa$) in thermoelectric composite materials using acoustic impedance mismatch and Debye model. Also, correlation between interface resistance (R$_{int}$) particle size of dispersed phase on k is discussed. In particular, $\kappa$ an oxide which consists natural superlattice Aurivillius (SrBi$_4$Ti$_4$O$_{15}$) as matrix perovsk...

In this study, the synergistic effect of particle size dispersed phase and interface thermal resistance (R$_{int}$) between phases on phonon conductivity ($\kappa_{ph}$) (1-x)La$_{0.95}$Sr$_{0.05}$Co$_{0.95}$Mn$_{0.05}$O$_3$/(x)WC thermoelectric composite, is demonstrated. Further, correlation R$_{int}$ Kapitza radius discussed using Bruggeman's asymmetrical model. particular, polycrystalline L...

The propagation of the normal zone in composite superconductors with high thermal resistance and high electrical contact resistance between the superconducting and the normal components of the conductor is analysed. It is shown that in certain conditions propagation can result from successive multiple splittings of the resistive domain generated. The minimum initiation current of this process h...

Thermal barrier coating (TBC) systems are coating systems containing a metallic bond coat and a ceramic top coat. TBCs are used in gas turbines for thermal insulation and oxidation resistance. Life prediction of TBCs is important as high-temperature exposure degrades the coatings through mechanisms such as thermal fatigue and the formation and growth of thermally grown oxides (TGOs). This thesi...

Thermal and mass transfer resistance at a liquid-gas interface could strongly affect the evaporation of micro/nanodroplet. One challenges in investigation heat across interfaces is that there are two modes, namely, conduction, an evaporating liquid surface. Interfacial conduction was often overlooked analysis droplet. In this work, we derive analytical expressions for to flow droplet from kinet...
