Crystallization kinetics behavior of ionic liquid [EMIM][BF4] confined in mesoporous silica matrices

This study focused on the crystallization kinetics behavior of pure ionic liquid (IL) (1-ethyl-3-methylimidazolium tetrafluoro borate; EMIMBF4) as well as IL confined in mesoporous silica matrices (termed as ionogel). X-ray photoelectron spectroscopy (XPS) and transient plane source (TPS) measurements have been used to explain ...

Novel Al2O3-SiO2 composite aerogels with high specific surface area at elevated temperatures with different alumina/silica molar ratios prepared by a non-alkoxide sol-gel method

This study investigated new sol-gel methods in the fabrication of Al₂O₃ - SiO₂ composite aerogels. Compared to conventional methods, the Al₂O₃ - SiO₂ composite aerogels were prepared and mixed together. Thermal conductivity of the composite aerogels was measured by an instrument, using a ...

Transient plane source (tps) sensors for simultaneous measurements of thermal conductivity and thermal diffusivity of insulators, fluids and conductors

This article describes the design, theory, advantages, and limitations of the TPS technique with a modified bridge. It also describes testing that has been done using the technique on a variety of solid materials from temperatures of 77 K to 1000 K. It was found that at ...

Effect of vinyl-modified silica and raw silica particles on the properties of as-prepared polymer-silica nanocomposite foams

This research studied the effect of the addition of vinyl-modified silica and raw silica additions to polymer-silica nanocomposite foams. Extensive physical property characterization was undertaken after their addition to quantify their influence. TEM found that silica particles added through the vinyl-modified silica dispersed better than ...

Thermal Conductivity of Alumina and Silica Nanofluids

The effects of particle size/shape, base fluid, and volumetric concentration on the thermal conductivity of nanofluids has been studied. It was found that decreasing the particle size leads to an increased thermal conductivity, and that using water as a base fluid led to the ...
