R-Curves in Al2O3 –- Al2O3/ZrO2 laminates

2005
In order to better understand the fracture behavior of Al2O3-Al2O3/ZrO2 laminates, controlled crack growth experiments were carried out. The method proposed consists of a three-point bending test of a sandwich beam in which a notched specimen is located in between two metallic bars.

Penta-Coordinated Al3+ Stabilized Active Pd Structures on Al2O3 Coated Palladium Catalysts for Methane Combustion.

Angewandte Chemie, 2019
Supported Pd catalysts are active in catalyzing the highly exothermic methane combustion reaction but tend to deactivate due to local hyperthermal environments.

Spectral selectivity of Al2O3-Cu-Al2O3 multilayer films

Solar Energy Materials, 1988
Abstract The optical properties of Al2O3/Cu/Al2O3 films are reported for different angles of incidence of light in the wavelength range 900-190 nm. The multilayer films exhibit > 90% reflectance in the wavelength range 900-600 nm and low visible transmittance (

Experimental study of the microstructural and mechanical properties of geopolymer paste with nano material (Al2O3)

Journal of Building Engineering, 2019
This article presents the effect of incorporating nano-Al2O3 particles into fly ash-based geopolymer pastes. Nano-Al2O3 particles were added to fly ash at dosages of 1%, 2%, and 3% by weight, and test samples of the same paste with no nano-Al2O3 were ...

Sputter-deposited Al2O3/Mo/Al2O3 selective absorber coatings

Thin Solid Films, 1980
Abstract The development of large-area magnetron sputtering sources has made sputtering attractive for selective absorber applications. In this paper we describe an investigation of Al2O3/Mo/Al2O3 (AMA) interference-type selective absorber coatings deposited by cylindrical magnetron sputtering onto low emittance molybdenum-coated glass and stainless ...
