TL;DR: In this paper, the effect of TMO addition on the electrical properties of Si-containing CGO20 ceramics was investigated, and it was found that Co3O4 is the most effective sintering aid, and the sintered temperature of CGO 20 can be reduced by over 200 °C by adding 0.5 at.% CoO4/3.

TL;DR: Being halogen free these hf-BILs offer a more environmentally benign alternative to ILs being currently developed for lubricant applications and are hydrophobic and hydrolytically stable liquids at room temperature.
Abstract: We report on the synthesis, characterisation, and physical and tribological properties of halogen-free ionic liquids based on various chelated orthoborate anions with different phosphonium cations, both without halogen atoms in their structure. Important physical properties of the ILs including glass transition temperatures, density, viscosity and ionic conductivity were measured and are reported here. All of these new halogen-free orthoborate ionic liquids (hf-BILs) are hydrophobic and hydrolytically stable liquids at room temperature. As lubricants, these hf-BILs exhibit considerably better antiwear and friction reducing properties under boundary lubrication conditions for steel-aluminium contacts as compared with fully formulated (15W-50 grade) engine oil. Being halogen free these hf-BILs offer a more environmentally benign alternative to ILs being currently developed for lubricant applications.

TL;DR: In this paper, a tetrafunctional epoxy resins with tetraethylenepentamine (TEPA) was used to confine an ionic liquid in a networked polymer.
Abstract: Networked polymers confining an ionic liquid, 1-ethyl-3-methylimidazolium bis(trifluoromethanesulfonyl) imide (EMImTFSI), were prepared by curing a mixture of bisphenol A diglycidyl ether (BADGE) and tetrafunctional epoxy resins with tetraethylenepentamine (TEPA) in the presence of ionic liquid. It was found that addition of the tetrafunctional epoxy resins was inevitable for better ionic liquid confinement. The ionic liquid confinement, ionic conductivity, mechanical strength, and morphology of the materials strongly depended on the ionic liquid content. At a low ionic liquid content ( 40 wt %), it did not confine the ionic liquid showing higher ionic conductivity with a low Young’s modulus. At a high ionic liquid content (>40 wt %), microphase separation between the ionic liquid and the epoxy networked polymer was observed by scanning electron ...
