Corrosion of Aluminum-Iron Eutectic Composites
The corrosion of Al-Al(,3)Fe eutectic composites and individual phases, prepared by employing directional solidification or special mechanical processing to vary microstructure, was studied under conditions of preferential corrosion of the Al(,3)Fe second phase in 2.4 M H(,2)SO(,4) and preferential …

Industrial application of eutectic freeze crystallization
South African industries are currently generating increasing quantities of hypersaline brine streams. These wastewater streams need to be processed in an ecologically friendly and economically favourable method to produce both purified water and salts.

Ice scaling in continuous eutectic freeze crystallization
Eutectic Freeze Crystallization (EFC) is a novel and potentially cost effective technique to treat industrial brines by the simultaneous crystallization of ice and salt under sub-eutectic conditions. Previous research has demonstrated that the formation of an ice scale layer on the cooling surfaces …

Synthesis of nanostructured materials in deep eutectic solvents
Deep eutectic solvents (DES), a new generation of non-toxic, eco-friendly and biodegradable solvents discovered in 2001 consist of a variety of cations and anions. These new sub-category of ionic liquids present interesting properties due to the hydrogen bonding between their components and are …

Impurities in crystals formed by eutectic freeze crystallization
… for the treatment of industrial waste brines; Eutectic Freeze Crystallization (EFC), can potentially separate these into pure water and its major constituent salts, which can be reused or sold. The feasibility of this technology is heavily invested in its capacity to produce pure salts. Thus, …

Multi-techniques Characterization of Mechanochemically Synthesized Deep Eutectic Solvents
<p>Deep eutectic solvent (DES) is the alternative and greener solvent in which two compounds, usually a hydrogen bond acceptor (HBA) and a hydrogen bond donor (HBD), are used. Two components form a complex network with strong intermolecular forces and show a lower melting point than those of the …

Development of a brine treatment protocol using Eutectic Freeze Crystallization
Hypersaline inorganic brines are generated from many global mining operations and the volume of these brines is increasing at an exponential rate. The environment and water resources in the vicinity of these mining operations are at a risk of being polluted as a result of this increase in brine …

Creep resistance of directionally solidified eutectic ceramics : experiments and model
… creep resistance of the directionally solidified eutectic ceramic of Al₂0₃/c-ZrO₂(Y₂0₃) was studied in the temperature range of 1200-1520⁰C both exprimentally and by the mechanistic dislocation model. The topologically continuous majority phase of Al₂0₃ has a nearly perfect growth texture in the …

Ionothermal Synthesis of High Silica Zeolites in Deep Eutectic Solvents (DES)
… have been synthesized using different deep eutectic solvents for the first time. ZSM-5 was made in tetrapropylammonium bromide/pentaerythritol. The reaction is affected by the amounts of seeding, water content, and organic structure-directing agent (SDA). Sodalite and ZSM-39 were prepared in …

Deep Eutectic Solvents for the Leaching of Cobalt from Oxide Ores
… this thesis examines the application of deep eutectic solvents (DESs) as a new approach for the extraction of Co from its ores. The work focussed on two ‘world-class’ Co-bearing ores types: a SSH Cu ore and a Ni(Co) laterite ore. Analysis using XRD, QEMSCAN®, and EPMA shows that a considerable …
