The sorption isotherm of a multiwall carbon nanotube in paraxylene is investigated through a pressure induced infiltration experiment. The inner space of the carbon nanotubes can be occupied by liquid molecules when an external pressure is applied so that the energy barrier caused by the lyophobic surface is overcome. The infiltration–defiltration curve is highly hysteretic, and therefore a sig...

Cadmium telluride (CdTe) tetrapods are synthesized with varying aspect ratios through multiple injections of the Te precursor, which provides an excellent means of controlling and tailoring the optical properties of the tetrapods. The self-assembly of CdTe tetrapods at the air/water interface is explored using the Langmuir-Blodgett (LB) technique due to potential use in solar cells arising from...

The simulation of carbon dioxide (CO2)-methane (CH4) mixed gas adsorption and the selectivity on zeolite 4A using Aspen Adsorption were studied. influence temperature ranging from 273 to 343 K, pressure up 10 bar various compositions CO2 in binary system simulated. findings study demonstrate that models are accurate. In addition, effects key parameters such as temperature, pressure, gases inves...

First-principles modeling, experimental, and thermodynamic methodologies were integrated to facilitate a fundamentally guided investigation of quaternary complex hydride compounds within the bialkali Na-Li-Al-H hydrogen storage system. The integrated approach has broad utility for the discovery, understanding, and optimization of solid-state chemical systems. Density functional theory ground-st...

A simple isotherm model has been developed for the type-5 equilibrium adsorption systems by considering the effects of both primary and secondary adsorptive sites. The model was applied to interpret experimental data describing water vapor adsorption capacities of four activated carbon adsorbents for relative vapor pressures from 0.0 to 0.95 and temperatures between 288 and 308 K. Good agreemen...

[1] We determined the equation of state (EOS) of three silicate liquid compositions by shock compression of preheated samples up to 127 GPa. Diopside (Di; Ca2Mg2SiO6) at 1773 K, anorthite (An; CaAl2Si2O8) at 1923 K and the eutectic composition Di64An36 at 1673 K were previously studied by shock compression to 38 GPa. The new data extend the EOS of each composition nearly to the Earth’s core‐man...

Low-pressure high-resolution hydrogen adsorption for the metal-organic framework MIL-101 are measured at 19.5 K and pressures below 57 kPa. The BET specific surface area and micropore volume are determined and compared to results from nitrogen adsorption at 77 K. Steps in the hydrogen adsorption isotherm are correlated to the pore structure of MIL-101.

By forcing an aqueous solution of N-lauroylsarcosine sodium salt and 8-anilino-1-naphthalenesulfonic acid ammonium salt in a hydrophobic nanoporous silica gel, the external work can be largely dissipated due to the amplified capillary effect. The sorption isotherm curve is two-staged, and the height and the width of stage-I infiltration plateau can be adjusted separately by controlling the liqu...
