Nanomaterials were obtained by dispersing silica nanoparticles in eutectic salt mixtures. The synthesis protocol was varied to obtain different nanomaterial samples of the same composition but different morphologies. The synthesis protocols that led to agglomerated nanoparticles resulted in coarse powders (Type-A samples) and the protocols that led to (un-agglomerated) well dispersed nanopartic...

Solid sorbents based on lithium orthosilicate (Li4SiO4) have shown promise for CO2 capture at high temperature. Improved sorption properties can be obtained by appropriate doping. In this study, different promoted Li4SiO4-based sorbents were prepared by addition of potassium carbonate and binary/ternary alkali (Li, K and Na) carbonate eutectic mixtures. The CO2 sorption properties of the sorben...

The nanostructure of a series of choline chloride/urea/water deep eutectic solvent mixtures was characterized across a wide hydration range by neutron total scattering and empirical potential structure refinement (EPSR). As the structure is significantly altered, even at low hydration levels, reporting the DES water content is important. However, the DES nanostructure is retained to a remarkabl...

The heterogeneous nucleation of primary Si and eutectic Si can be attributed to the presence of AlP. Although P, in the form of AlP particles, is usually observed in the centre of primary Si, there is still a lack of detailed investigations on the distribution of P within primary Si and eutectic Si in hypereutectic Al-Si alloys at the atomic scale. Here, we report an atomic-scale experimental i...

Eutectic solvent can solubilize high amount of some therapeutic compounds. Volatile eutectic solvent is interesting to be used as solvent in the preparation of nanosuspension with emulsion solvent evaporation technique. The mechanism of transformation from the eutectic emulsion to nanosuspension was investigated in this study. The 30% w/w ibuprofen eutectic solution was used as the internal pha...

CMOS compatible metallic hermetic sealing using Al-Ge eutectic alloy for packaging MEMS devices for harsh environments has been developed. The effects of various bonding parameters on the bond quality have been extensively reported. The reliability of this eutectic joint subjected to high operating temperatures involved in deep oil well logging application has been investigated with the specifi...

Some salts such as alkali metal and silver per chlorates, cobaltchloride and their complexes with ligands such as acetone, acetonitrile,dimethylsulphoxide, pyridine, and N-methyl and N,N dimethyl formamidesdissolve in thermotropic nematic liquid crystals providing information onthe metal-ion ligand interactions. The H, H and the metal ion resonanceshave been used to derive t...

The kinetics of melt crystallization of binary eutectic forming organic mixtures in non-flow systems with cooling from below for the preferential crystallization of one component alone have been studied experimentally. The effect of subcooling, superheating and the initial concentration of the melt on the crystallization kinetics have been studied. Based on the experimental data, a correlation ...

Alkyl glycosides are biodegradable surfactants with excellent physico-chemical properties. Although their wide-range application is considered ecofriendly, synthesis not due to the need for toxic organic solvents and corrosive acids as catalysts. Moreover, chemical results in complex mixtures rather than defined compounds. To overcome both disadvantages well limited solubility of sugars solvent...
