      Modeling of thermal conductivity in high performing thermoelectric materials 

      Hatzikraniotis, E.; Kyratsi, Theodora; Paraskevopoulos, K. M. (Institute of Physics Publishing, 2017)
      The enhanced TE-performance in Mg2Si-Mg2Sn based pseudo-binaries is presented, which is attributed to low thermal conductivity. Sn-Si alloying, reduces the lattice thermal conductivity due to mass fluctuation. Furthermore, ...

      A note on the convergence rate of the finite element method for singularly perturbed problems using the Shishkin mesh 

      Xenophontos, Christos A. (2003)
      We consider the numerical approximation of singularly perturbed problems by the h version of the finite element method on a piecewise uniform, Shishkin mesh. It is well known that this method yields uniform approximations, ...

      Numerical modeling of self-propagating reactions in Ru/Al nanoscale multilayer foils 

      Mücklich, F.; Woll, K.; Gunduz, I. E.; Pauly, C.; Doumanidis, C. C.; Son, S. F.; Rebholz, Claus (2015)
      The Ru/Al system integrates high energy density and high product ductility and serves as an alternative for utilization as nanoscale reactive multilayer. We present a modeling study that relates the Ru-Al phase transformations ...

      Optical probing of anisotropic heat transport in the quantum spin ladder Ca 9La 5Cu 24O 41 

      Otter, M.; Athanasopoulos, G.; Hlubek, N.; Montagnese, M.; Labois, M.; Fishman, D. A.; Haan, F. De; Singh, S.; Lakehal, D.; Giapintzakis, John; Hess, C.; Revcolevschi, A.; Loosdrecht, P. H. M. Van (2012)
      A transient thermal imaging technique is used to monitor heat diffusion at the surface of the antiferromagnetic spin ladder material Ca 9La 5Cu 24O 41. This material shows highly anisotropic thermal conductivity due to a ...

      Simulation based design of a thermoelectric energy harvesting device for aircraft applications 

      Lyras, M.; Zymaride, L.; Kyratsi, Theodora; Louca, Loucas S.; Becker, T. (American Society of Mechanical Engineers, 2017)
      Maintenance is, amongst others, a key cost driver in aircraft operation. A wireless monitoring device might be able to reduce these costs. However, the supply of energy to such system via power lines would result in ...
