Thermal Conductivity and Anisotropy of Layered Oxides
Most importantly, deep gratitude is extended to my wife, Jodi Sparks, who tolerates my long hours immersed in coursework or in the lab and was even willing to follow me across the country so that I can accomplish my dreams. The thermal conductivity of a series of complex layered oxides including RE 2 SrAl 2 O 7 , with different rare-earth (RE) ions, and Sr 2 Nb 2 O 7 has been measured up to 100...
متن کاملp 9 n-Type Transverse Thermoelectrics: A Novel Type of Thermal Management Material
In this paper we review the recently identified p 9 n-type transverse thermoelectrics and study the thermoelectric properties of the proposed candidate materials. Anisotropic electron and hole conductivity arise from either an artificially engineered band structure or from appropriately anisotropic crystals, and result in orthogonal p-type and n-type directional Seebeck coefficients, inducing a...
متن کاملSchemes for and Mechanisms of Reduction in Thermal Conductivity in Nanostructured Thermoelectrics
Nonequilibrium molecular dynamics (NEMD) simulations were performed to investigate schemes for enhancing the energy conversion efficiency of thermoelectric nanowires (NWs), including (1) roughening of the nanowire surface, (2) creating nanoparticle inclusions in the nanowires, and (3) coating the nanowire surface with other materials. The enhancement in energy conversion efficiency was inferred...
متن کاملUltralow thermal conductivity in disordered, layered WSe2 crystals.
The cross-plane thermal conductivity of thin films of WSe2 grown from alternating W and Se layers is as small as 0.05 watts per meter per degree kelvin at room temperature, 30 times smaller than the c-axis thermal conductivity of single-crystal WSe2 and a factor of 6 smaller than the predicted minimum thermal conductivity for this material. We attribute the ultralow thermal conductivity of thes...
متن کاملIncreased Thermal Conductivity in Metal-Organic Heat Carrier Nanofluids
Metal-organic heat carriers (MOHCs) are recently developed nanofluids containing metal-organic framework (MOF) nanoparticles dispersed in various base fluids including refrigerants (R245Fa) and methanol. Here, we report the synthesis and characterization of MOHCs containing nanoMIL-101(Cr) and graphene oxide (GO) in an effort to improve the thermo-physical properties of various base fluids. MOH...
