A number of high-entropy alloys (HEAs) in the TiVZrNbHf system have been synthesized by arc melting and systematically evaluated for their hydrogen sorption characteristics. total 21 with varying elemental compositions were investigated, 17 them form body-centered-cubic (bcc) solid solutions as-cast state. 15 either face-centered-cubic (fcc) or body-centered-tetragonal (bct) hydrides after exposure to gaseous per metal ratios (H/M) as high 2.0. Linear trends are observed between volumetric...
Understanding the short-range molecular motions of organic ionic plastic crystals is critical for application these materials as solid-state electrolytes in electrochemical devices such lithium batteries. However, theory short-range-motions was originally developed simple and does not take account strong interionic interactions that are present crystals. Here we report a fundamental investigation dynamic behavior an archetypal example triethyl(methyl)phosphonium bis(fluorosulfonyl)amide...
The carbonation of CaO-based materials at high temperatures (e.g. >600 °C) is a promising method capturing CO2 emitted from, e.g. the combustion carbonaceous fuels. resulting CaCO3 can be regenerated by calcination temperature which equilibrium partial pressure exceeds that local 950 °C). A process involving repeated cycles and calcareous material called calcium looping. capacity sorbent to accept reject over many governed number factors, such as chemical composition, surface morphology pore...
Doping Ba<sub>2</sub>YRuO<sub>6</sub> with Sr induces octahedral tilting and significantly impacts on the magnetic properties.
A novel compound for carbon capture and storage (CCS) applications, the 6H perovskite Ba4Sb2O9, was found to be able absorb CO2 through a chemical reaction at 873 K form barium carbonate BaSb2O6. This absorption shown reversible regeneration of original Ba4Sb2O9 material upon heating above 1223 accompanied by release CO2. combined synchrotron X-ray diffraction, thermogravimetric, microscopy study carried out characterize first physical properties then analyze structural evolution formation...
We positively identified and quantified the solid-state phases involved in carbonation/decarbonation cycle of Na2ZrO3 when used for carbon capture. Previous work had only qualitatively inferred present using diffraction pattern matching thermogravimetric analysis. Here, we Rietveld-refinement method to analyze synchrotron X-ray neutron powder data from samples treated ex situ. then confirmed extended our findings by situ a purpose-built gas-flow apparatus. This allowed us resolve...
In recent years, a number of novel ceramic oxide materials have emerged that are capable absorbing CO2 at high temperatures (>500C) while remaining stable over large cycles and wide range [1]. The most promising been considered for carbon capture applications – specifically, use in combustion chambers the smoke stacks power plants where gases which contain primarily mixture N2 temperature. Compared to other sequestration technologies, these ceramics some advantages (eg. chemisorption...
