Adsorption of benzene, phenol, propane and carbonic acid molecules on oxidized Al(111) and alpha-Al2O3(0001) surfaces: A first-principles study [PDF]
We present the results of ab initio calculations describing the adsorption of certain small organic molecules on clean and oxidized Al(111) surfaces as well as on the alpha-Al2O3(0001) surface. Our results show that adsorption of benzene on the clean and oxidized Al(111) surfaces is generally weak, the adsorption energy being at most around -0.5 eV per

Clustering and Precipitation during Early-Stage Artificial Aging of Al–Si–Mg(–Cu) Foundry Alloys
High-Si aluminum foundry alloys are an important material class for products with complex 3D geometries where casting is the most suitable production method. With Mg and/or Cu additions, these alloys gain strength upon heat treatment due to the formation

Spectrometric study of condensed phase species of thorium and palladium-based modifiers in a complex matrix for electrothermal atomic absorption spectrometry [PDF]
The chemical and morphological transformations of condensed phase species of a thorium-based modifier were studied over the temperature range 200–2500 °C, without and with the presence of aluminium and silicon as matrix components, and in some instances,

Crack Detection Method Applied to 3D Computed Tomography Images of Baked Carbon Anodes
Carbon anodes used in the aluminium industry were imaged through destructive and non-destructive testing (NDT) methods. For the latter case, computed tomography (CT), which has previously been used to map the 3D apparent density distribution, was ...

First Industrial Scale Process Concept for the Reengineered Pedersen Process within ENSUREAL
The Pedersen Process was developed at the beginning of the 20th century as an alternative process to the Bayer route for producing alumina Al2O3. A successful operation in an industrial environment took place in Norway from 1925 to 1969.

A super-ductile alloy for the die-casting of aluminium automotive body structural components [PDF]
Super-ductile die-cast aluminium alloys are critical to future light-weighting of automotive body structures. This paper introduces a die-cast aluminium alloy that can satisfy the requirements of these applications.

Drop-coated Titanium Dioxide Memristors [PDF]
The fabrication of memristors by drop-coating sol-gel Ti(OH)$_4$ solution onto either aluminium foil or sputter-coated aluminium on plastic is presented. The gel layer is thick, 37$\mu$m, but both devices exhibit good memristance I-V profiles. The drop coated aluminium foil memristors compare favourably with the sputter-coated ones, demonstrating an ...
