The transport of gas in clay-based materials is dominated by diffusion. SCK CEN has studied and recorded an extensive data set diffusion coefficients gases various saturated clays (Boom Clay, Opalinus Callovo-Oxfordian claystone bentonites) used Europe as host formations or engineered barrier systems the context deep geological disposal high intermediate level nuclear wastes. However, partially...

We present experimental results on the mechanical behavior of static granular assemblies confined in a vertical column. Our measurements confirm the universal Janssen scaling for the stress saturation curve. We show consequently, in the context of isotropic elasticity, a relation between the Poisson ratio and the granular packing fraction. Moreover, using a systematic study of the overshoot eff...

Hesperidin nanocrystals was generated by high pressure homogenization. The physicochemical properties of a spray dried hesperidin nanocrystals were investigated including to re-dispersion, crystalline state, kinetic solubility, dissolution velocity. Hesperidin nanosuspension with concentration of 10% (w/v) was dried by a Mini Spray-dryer B-190. Photon correlation spectroscopy (PCS) and laser di...

With the ever-increasing demand for energy, research on energy storage materials is imperative. Thereinto, dielectric are regarded as one of potential candidates application in advanced pulsed capacitors by reason their ultrahigh energy-storage density, low loss, and good thermal stability. Among numerous storage, sodium bismuth titanate (Bi0.5Na0.5TiO3, BNT) with high saturation polarization, ...

We reexamine the relationship between pyroxene composition and near-infrared absorption bands, integrating measurements of diverse natural and synthetic samples. We test an algorithm (PLC) involving a two-part linear continuum removal and parabolic fits to the 1 and 2 lm bands—a computationally simple approach which can easily be automated and applied to remote sensing data. Employing a suite o...

Saturation H2 uptake in a series of microporous metal-organic frameworks (MOFs) has been measured at 77 K. Saturation pressures vary between 25 and 80 bar across the series, with MOF-177 showing the highest uptake on a gravimetric basis (7.5 wt %) and IRMOF-20 showing the highest uptake on a volumetric basis at 34 g/L. These results demonstrate that maximum H2 storage capacity in MOFs correlate...

It has been reported that intake of ω-3 polyunsaturated fatty acids (PUFAs) reduces the risk of coronary heart disease. It also influences bile composition, decreasing biliary cholesterol saturation in the bile of patients with gallstones. In addition to bile composition disturbances, gallbladder hypomotility must be a cofactor in the pathogenesis of cholelithiasis, as it leads to the prolonged...

We propose new isoreticular metal-organic framework (IRMOF) materials to increase the hydrogen storage capacity at room temperature. Based on the potential-energy surface of hydrogen molecules on IRMOF linkers and the interaction energy between hydrogen molecules, we estimate the saturation value of hydrogen sorption capacity at room temperature. We discuss design criteria and propose new IRMOF...
