Gas hydrate occurs in reservoirs a solid form. At present, the conventional exploitation method is to decompose and then extract resulting gaseous gas. Therefore, occurrence law of gas reservoir great significance for study seepage productivity. Adsorption, as an important mode, has been widely concerned research on shale reservoirs. However, adsorption problem not received enough attention. In...

In this study, biochar produced by low-temperature pyrolysis from palm leaves was treated with phosphoric acid in order to increase the sorption efficiency of Cr (VI) aqueous solutions. Numerous characterization experiments using BET surface area, FE-SEM and FT-IR showed that acid-treated (TBC-P) covered P particles. comparison biochar, TBC-P also had more oxygenated functional groups, pore siz...

It was recently reported that polyanion/DNA/polycation ternary polyplexes markedly improve gene transfection activity in comparison with the original DNA/polycation binary polyplexes. In this study to explore the influence of the polyanion on the physico-chemical properties and biological activity of polyanion/pDNA/polycation ternary polyplexes four types of biocompatible polyanions were select...

van der Waals density functional theory (vdW-DFT) and semiempirical grand canonical Monte Carlo (GCMC) calculations are used to predict the thermodynamics and methane storage capacity of 18 metal-substituted variants of the metal−organic framework (MOF) M-DOBDC (DOBDC = 2,5-oxidobenzene-1,4dicarboxylate). Methane adsorption enthalpies (ΔH) on the benchmark Mgand NiDOBDC systems were calculated ...

A cell model is developed and validated to analyze the performance of polymer electrolyte membrane water electrolysis (PEMWE) stacks systems. It used characterize oxygen evolution reaction (OER) activity on a TiO2-supported IrO2 catalyst an unsupported powder catalyst. Electrochemical, stack, system thermoneutral potentials are defined determined for isothermal non-isothermal stack operation. C...

The physical limits for methane storage and delivery in nanoporous materials were investigated, with a focus on whether it is possible to reach a methane deliverable capacity of 315 cm(STP)/cm in line with the adsorption target established by the ARPA-E agency. Our efforts focused on how both geometric and chemical properties, such as void fraction (Vf), volumetric surface area (Sv), and heat o...
