Viable Scandium Extraction from Bauxite Residue at Pilot Scale
Scandium extraction from the Greek bauxite residue has been demonstrated at an industrial pilot plant at MYTILINEOS. This work comes as the result of the H2020 SCALE collaborative research project.

Geometry Effects at Atomic-Size Aluminium Contacts [PDF]
We present electronic structure calculations for aluminium nanocontacts. Addressing the neck of the contact, we compare characteristic geometries to investigate the effects of the local aluminium coordination on the electronic states. We find that the Al 3pz states are very sensitive against modifications of the orbital overlap, which has serious ...

A burgeoning number of studies are demonstrating aluminium in human brain tissue. While research has both quantified and imaged aluminium in human brain tissue in neurodegenerative and neurodevelopmental disease there are few similar data for brain ...

Granular aluminium as a superconducting material for high-impedance quantum circuits [PDF]
Superconducting quantum information processing machines are predominantly based on microwave circuits with relatively low characteristic impedance, about 100 Ω, and small anharmonicity, which can limit their coherence and logic gate fidelity1,2.

Empirical Model of Bearing Temperature Saturation at Asahan II Hydro-Turbine-Generator
Bearing temperature saturation is a common phenomenon observed during no-load run and full-load tests of Asahan II hydro-turbine-generators. Despite complex heat transfer mechanism involved behind it, simple model can be constructed to predict bearing ...

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.

The Aluminyl Anion: A New Generation of Aluminium Nucleophile.
Trivalent aluminium compounds are well known for their reactivity as Lewis acids/electrophiles, a feature that is exploited in many pharmaceutical, industrial and laboratory-based reactions. Recently, a series of isolable aluminium(I) anions ('aluminyls')

In the present paper, the microstructures of three kinds of in-situ reinforcements Al-Ti-C, Al-Ti-B, and Al-Ti-B-C-Ce were deeply investigated using a combination of scanning electron microscopy, X-ray diffraction spectroscopy, and transmission electron ...

Atomistic Mechanisms for the Nucleation of Aluminium Oxide Nanoparticles [PDF]
A predictive model for nanoparticle nucleation has not yet been successfully achieved. Classical nucleation theory fails because the atomistic nature of the seed has to be considered since geometrical structure as well as stoichiometry do not always match the bulk values.

Electrochemical extraction of europium from molten fluoride media [PDF]
This work concerns the extraction of europium from molten fluoride media. Two electrochemical ways have been examined: (i) the use of a reactive cathode made of copper and (ii) the co-deposition with aluminium on inert electrode, leading to the formation
