The orientation and distribution of the filler in hexagonal boron nitride (hBN) coated with iron oxide (Fe3O4@hBN)/polyimide (PI) composite sheets were controlled via magnetic field treatment (MFT) to enhance the effective thermal conductivity (TC) in the out‐of‐plane direction. Filler chain...
Iron Oxide (Fe3O4) nanoparticles were deposited on the surface of low density polyethylene (LDPE) particles by solvothermal method. A magnetic field was introduced to the preparation of Fe3O4/LDPE composites, and the influences of the magnetic field on thermal conductivity and dielectric properties...
Based on this mechanism, it is successfully demonstrated that the crystalline quality and hence the conductivity of GZO thin films can be improved by using a GZO buffer layer. 展开 关键词: nucleation and growth sputtering thin films transparent conductive oxide zinc oxide ...
The ab-plane thermal conductivity /spl kappa//sub ab/(T), thermal diffusivity /spl alpha//sub ab/(T) and thermoelectric power S/sub ab/(T) were measured for the highly-oriented Ag-doped superconducting materials Sm/sub 1+2x/Ba/sub 2+x/Cu/sub 3+x/O/sub 7+5x/ (X = 0.1 /spl ...
An experimental investigation on water-based nanofluids containing iron oxide (Fe2O3) in concentrations ranging between 5 and 20% in mass is presented. The purpose of this study is to measure thermal conductivity and dynamic viscosity of these fluids, as a starting point to study the heat ...
Summary This document is part of Subvolume A 'Part A: Garnets and Perovskites' of Volume 12 'Magnetic and Other Properties of Oxides and Related Compounds' of Landolt-Brnstein - Group III Condensed Matter. Substances contained in this document (element systems and chemical formulae) Al-Fe-O...
Thethermal conductivityof UO2and mixedoxidelight water reactor(MOX LWR) fuels decreases as a result of reactorburnup. In this chapter, the phenomena causing this degradation are presented, and the effect of the most influential parameters is discussed. Information useful for the interpretation and ...
We investigate the temperature-dependent thermal conductivity (k) of aqueous and nonaqueous stable nanofluids with average particles size of 8 nm stabilized with a monolayer of surfactant. Iron oxide (Fe3O4) nanoparticles are synthesized by a coprecipitation technique and are characterized by powder ...
We study the effect of nanoparticle aggregation on thermal conductivity (k), viscosity(η)and size distribution of a stable and unstable nanofluid of iron oxide(Fe3O4)and copper oxide (CuO), respectively. The k,η, and size are found to be time independent inFe3O4while they are time dep...
It was found that 0.05 % concentration of copper oxide nanoparticle with 5% concentration of oleic acid surfactant resulting stable dispersion in kerosene. The thermal conductivity enhancement of about 16% was observed of 0.05% CuO nanofluid with surfactant vis-a-vis those of Kerosene. It was also...
