KSb5S8: A wide bandgap phase-change material for ultra high density rewritable information storage
(2003)
The reversible glassformation and glass crystallization properties of KSb3S8 was described. On the basis of glass transition and crystallization kinetics of KSb5S8, it was found that the crystallization rate and assoicated ...
Crystal growth of ternary and quaternary alkali metal bismuth chalcogenides using Bridgman technique
(Affiliation: Dept. of Chemistry, Center of Fundamental Mat. Research, Michigan State University, East Lansing, MI 48824-1322, United StatesCorrespondence Address: Kyratsi, T.Dept. of Chemistry, Center of Fundamental Mat. Research, Michigan State University, East Lansing, MI 48824-1322, United States, 2001)
Our exploratory research in new thermoelectric materials has identified the ternary and quaternary bismuth chalcogenides β-K2Bi8Se13, K2.5Bi8.5Se14 and K1+xPb4-2xBi7+xSe15, to have promising properties for thermoelectric ...
Lattice thermal conductivity of K 2(Bi 1-zSb z) 8Se 13 solid solutions
(2004)
The influence of the Bi/Sb partial substitution to the lattice thermal conductivity of the K 2(Bi 1-zSb z) 8Se 13 solid solution series was studied. The variation of the lattice thermal conductivity with comparison was ...
Choi-Wiliams time frequency analysis of a three degree freedom non-linear system
(Katholieke Universiteit Leuven, 2006)
The response of a non-linear mechanical oscillator, depending on the type of non-linearity, to an excitation of particular harmonic might contain sub- and super-harmonics, transients and chaotic components. The conventional ...
N-to-p transition on K2Bi8-xSbxSe 13 series
(Affiliation: Department of Mechanical and Manufacturing Engineering, University of Cyprus, 1678 Nicosia, CyprusAffiliation: Department of Chemistry, Michigan State University, East Lansing, MI 48824, United StatesAffiliation: Department of Physics, Aristotle University of Thessaloniki, 54124 Thessaloniki, GreeceCorrespondence Address: Kyratsi, Th.Department of Mechanical and Manufacturing Engineering, University of Cyprus, 1678 Nicosia, Cyprus, 2006)
β-K2Bi8Se13 and its solid solutions have been found to be interesting for thermoelectric investigations mainly due to their low thermal conductivity and highly anisotropic electrical properties. Solid solution series of ...
Analytical target cascading for the design of an advanced technology heavy truck
(American Society of Mechanical Engineers (ASME), 2002)
Analytical target cascading (ATC) is a methodology that can be used during the early development stages of large and complex systems for propagating desirable overall product targets to appropriate individual specifications ...
Thermoelectric properties and site-selective Rb+/K+ distribution in the K2-xRbxBi8Se13 series
(2003)
β-K2Bi8Se13 possesses promising thermoelectric properties whereas Rb2Bi8Se13 does not. The formation of solid solutions between these two compounds was attempted to study the alkali metal distribution in the structure and ...
Thermoelectric properties of K 2Bi 8Se 13-xS x solid solutions
(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 ...
Linear analysis of generalized turbulent hyperbolic flow in a rotating frame
(2007)
We apply inviscid rapid distortion theory to the generalized case of turbulent hyperbolic flow in a rotating frame and investigate the dependence of the evolution of the turbulent kinetic energy on the frame rotation rate. ...
