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 the slowing down of crystallization process of IL in confinement. Thermal conductivity of the IGs was measured using pellets of #IG2 and #IG3 with the ...

Thermal optimisation of metal hydride reactors for thermal energy storage applications

Metal hydrides (MHs) have been considered as thermal energy storage (TES) materials for concentrated solar thermal applications. In this study, a TES system based on MgH2 was designed, constructed and optimized. The thermal conductivity of the MgH2/TiB2/ENG powder was measured using the transient plane source technique. It was found that the thermal conductivity of a MgH2/TiB2/ENG pellet pressed at 223 MPa for 5 minutes and measured in the ...

Simultaneous measurements of thermal conductivity and diffusivity of Se(85-x)Te(15)Sb(x) (x = 2, 4, 6 and 10) chalcogenide glasses at room temperature

In this study, the transient plane source (TPS) technique was used to measure the thermal conductivity and thermal diffusivity of Se85-xTe15Sbx (x = 2, 4, 6, 8, and 10) pellets. These values were then used to determine the specific heat per unit volume of these glasses in the composition range of investigation. It was found that 4 at% of Sb (antimony) results in the critical composition of ...

Advancement of system designs and key engineering technologies for materials-based hydrogen storage 

Aspects of hydrogen distribution systems need improvement for their applications in fuel cell vehicles. In this paper, chemical and physical characteristics of the H2 storage material, sodium aluminum hydride (SAH), were examined after the samples were compacted and Expanded Natural Graphite (ENG) worms were added. A Thermal Constants Analyzer (TPS) measured the thermal conductivity of the SAH pellets with (ENG) worms using the Transient Plane Source (TPS) method. Results showed ...
