Thermal conductivity of orientationally-disordered crystals under high pressure

, 1983
The transient hot-wire method was used to study the effects of temperature and pressure on the thermal conductivity, λ, of several molecular substances showing varying degrees of disorder in molecular orientation. Molecular solids both in the plastic and

Measurement Of Thermal Conductivity Of Thermally Low-Conducting Materials

, 1995
The thermal conductivity of a building material is a necessary parameter in estimating the cooling load of a building. Cooling load estimates are quite important in selecting building materials especially in hot-climate areas as in Qatar or the Middle East.

Resistance Rapid Heating of Aluminum Coatings in an Extreme High Vacuum–Adequate Atmosphere for Hot Stamping

Advanced Engineering Materials, EarlyView.
The subject of this work is the development of a corrosion‐protective coating on steel sheets for form hardening. Rapid heating in an extreme high vacuum (XHV)‐adequate atmosphere is a useful method to prevent oxidation during alloying of 22MnB5 and aluminum to obtain a metallurgical bonding.

Pyramidal Structures on Yttria‐Stabilized Zirconia after High Temperature Exposure at 1500°C: New Features on an Old Material

Advanced Engineering Materials, EarlyView.
New features on yttria‐stabilized zirconia after exposure at 1500°C: Newly discovered pyramidal structures on an old material. After exposure at 1550°C on the cross section of YSZ new features, namely pyramidal structures are discovered. These structures grow with time, increase in numbers, appear as singularities, are often arranged in strings, and ...

The effect of alumina/water nanofluid particle size on thermal conductivity

, 2013
[[abstract]]This study examines the effect of particle size, temperature, and weight fraction on the thermal conductivity ratio of alumina(Al2O3)/water nanofluids. A Al2O3/water nanofluid produced by the direct synthesis method served as the experimental

Dielectric Barrier Discharge Plasma Deoxidation of Natively Oxide Layer of Copper Powders in a Fluidized Bed

Advanced Engineering Materials, EarlyView.
This paper presents a novel approach to reducing oxide layers on metal powders using low‐temperature hydrogen dielectric barrier discharge plasmas at atmospheric pressure. Unlike conventional hydrogen‐plasma reductions, the powders do not contact the plasma directly.
