      Thermal conductivity measurements of anisotropic bulk samples using the 3ω method 

      Athanasopoulos, G. I.; Svoukis, E.; Viskadourakis, Z.; Giapintzakis, John (Affiliation: Mechanical and Manufacturing Engineering, University of Cyprus, 75 Kallipoleos Avenue, Nicosia, 1678, CyprusAffiliation: Materials Science and Technology Department, University of Crete, P.O. Box 2208, Heraklion Crete 710 03, GreeceCorrespondence Address: Athanasopoulos, G. I.Mechanical and Manufacturing Engineering, University of Cyprus, 75 Kallipoleos Avenue, Nicosia, 1678, Cyprus, 2010)
      The 3ω method has been applied to measure the anisotropic thermal conductivity of single crystals of SiO2 (quartz) and La 14-yCayCu24O41 (y = 9 and 10). A two-dimensional heat conduction model along with properly oriented ...

      Thermoelectric properties of K 2Bi 8Se 13-xS x solid solutions 

      Kyratsi, Theodora; Lal, S.; Hogan, T.; Kanatzidis, M. G. (Affiliation: Department of Chemistry, Michigan State University, East Lansing, MI 48824, United StatesAffiliation: Department of Mechanical and Manufacturing Engineering, School of Engineering, University of Cyprus, Nicosia, CyprusAffiliation: Department of Electrical and Computer Engineering, Michigan State University, East Lansing, MI 48824, United StatesCorrespondence Address: Kyratsi, T.Department of Chemistry, Michigan State University, East Lansing, MI 48824, United States, 2006)
      Derivatives of β-K 2Bi 8Se 13 are an interesting series of materials for thermoelectric investigations due to their very low thermal conductivity and highly anisotropic electrical properties. Up to now substitutions on the ...

      Thermoelectric properties of K2Bi8-xSbxSe13 solid solutions and Se doping 

      Kyratsi, Theodora; Dyck, J. S.; Chen, W.; Chung, D. Y.; Uher, C.; Paraskevopoulos, K. M.; Kanatzidis, M. G. (Affiliation: Department of Chemistry, Michigan State University, East Lansing, MI 48824, United StatesCorrespondence Address: Kyratsi, T.Department of Chemistry, Michigan State University, East Lansing, MI 48824, United States, 2002)
      Our efforts to improve the thermoelectric properties of β-K2Bi8Se13, led to systematic studies of solid solutions of the type β-K2Bi8-xSbxSe13. The charge transport properties and thermal conductivities were studied for ...

      When structure makes a difference: Computation of rotating wall-bounded flows with an algebraic structure-based model 

      Kassinos, Stavros C.; Langer, C. A.; Kalitzin, G.; Iaccarino, G. (Affiliation: Department of Mechanical and Manufacturing Engineering, University of Cyprus, Nicosia 1678, CyprusAffiliation: Center for Turbulence Research, Stanford University, Stanford, CA 94305, United StatesCorrespondence Address: Kassinos, S.C.Department of Mechanical and Manufacturing Engineering, University of Cyprus, Nicosia 1678, Cyprusemail: kassinos@ucy.ac.cy, 2005)
      Two linear eddy-viscosity models, the ν 2-f and κ-ω models, have been combined with an algebraic structure-based algorithm for the evaluation of the Reynolds stresses. This closure was originally designed as an integral ...
