Aggregation and dispersion phenomena in the quartz

Aggregation and dispersion phenomena in the quartz-hematite system in the presence of polymers were analyzed through the measurement of adsorption density of polymers, turbidity of mineral suspensions, and zeta potential distributions. All the tests were performed on single minerals as well as on their 1:1 mixtures (by volume). A procedure was developed to determine the composition of the

Ammonia is considered to be a potential medium for hydrogen storage, facilitating CO2-free energy systems in the future. Its high volumetric hydrogen density, low storage pressure and stability for long-term storage are among the beneficial characteristics of ammonia for hydrogen storage. Furthermore, ammonia is also considered safe due to its high auto ignition temperature, low condensation

This is the case of mercury in poorly reactive electrolytes (Ref 1). Noble metals like platinum or gold behave as ideal polarizable electrodes within a limited range of potential. However, on most metals, especially the corrodible ones, reactions with electron transfer across the interface (electrochemical reactions) occur, leading to charge transfer currents, or faradic current.

The use of electrolyte additives is one of the most effective and economical ways to improve battery performance by stabilizing the electrode/electrolyte interface. In this work, we identified that fluoroethylene carbonate (FEC), which is one of the important electrolyte additives, had different impacts on anode and cathode, by investigating a graphite anode and a LiMn 2 O 4 cathode through

Fluoride removal from brine with ion exchange resin

The presence of fluoride has caused a number of complications in various industrial applications. In the sodium sulfate salt splitting technology developed by NORAM Engineering and Constructors, the undesirable fluoride ions in brine solution could cause the breakdown of the protective passivation layer on the titanium anode, resulting in pit corrosion or spalling of the coating on the

Physical-chemical properties of the molten salt system Na3AlF6-ExAlF3-5wt%Al2O3-CaF2-KF-LiF for aluminum electrolysis were investigated in this paper. The combined effects of ExAlF3, KF and LiF on the liquidus temperatures, alumina dissolution, aluminum solubility, electrical conductivity were discussed. A regression equation describing liquidus temperatures was derived. The effects of lithium

Understanding Variation in Partition Coefficient, Kd,

Multiple species typically exist in groundwater and the effect of their individual Kd values have a profound effect on the overall Kd value. For example, consider a system that consists of a contaminant or radionuclide with 2 equal concentration species that are kinetically slow at converting between each composition state; one with a Kd of 0 ml/g and the second with a Kd of 1,000 ml/g.

The performance of aluminium electrolysis in cryolite

Additions of more than 1 wt% of KF were found toud reduce the current efficiency significantly. Blending KF and LiF didn't raise currentud efficiency compared with single addition of LiF. MgF2 has a positive effect on currentud efficiency.

High-energy nickel cobalt manganese oxides have been studied intensively as cathode materials for lithium-ion batteries. However, several hurdles need to be overcome to adopt these cathodes in commercial lithium-ion batteries. Herein, aluminum oxide (Al 2 O 3) coating was applied to high-energy nickel cobalt manganese oxides (HE-NCM, Li 1.33 Ni 0.27 Co 0.13 Mn 0.60 O 2+d) by atomic layer

Handbook on Electroplating with Manufacture of

Alkaline electrolytes (NaOH, KOH) form protective anodic films on the workpiece surface and prevent metal dissolution. An exception is tungsten (qv), which can be machined only in strong alkali. The only practical electrolytes are neutral salt solutions in which a metal ion precipitates as a sludge.
