摘要： A corrosion-resistant superhydrophobic and superoleophilic modified poly(vinylidene fluoride)-based bulk material with oil-water separation ability is fabricated through a facile method of molding and sintering process. Fluorinated ethylene propylene was added as the one of the cross-linking agents. Nanometer silica (SiO2) and carbon nanotubes (CNTs) were added into the bulk material to construct the necessary reticulate papillae structures for superhydrophobic surface. NH4HCO3 was added as a pore-forming reagent in order to realize porous structure and oil-water separation. The bulk material can be designed to different appearances, such as cuboids, cylinder and sealing rings. The resulting bulk material shows excellent superhydrophobic and superoleophilic with a water contact angle of 164A degrees and oil contact angle of almost 0A degrees. As the SiO2 and CNTs filled the entire bulk material, any section of the bulk material shows excellent superhydrophobicity. The thermal resistance of the bulk material was improved due to the introduction of nanoparticles. The corrosion resistance of the superhydrophobic bulk material was investigated in an aqueous NaCl solution (3.5%). The results show that the prepared composite bulk material is effective in corrosion resistance, primarily due to the barrier effect of Cassie-Baxter model of superhydrophobic surface. It is believed that this bulk material would be an engineering material for large-scale application.

关键词： Fracture networks   DFN   Stochastic modeling   Open source   Matlab   Fluid flow   Simulations  

摘要： Rapidly growing topic, the discrete fracture network engineering (DFNE), has already attracted many talents from diverse disciplines in academia and industry around the world to challenge difficult problems related to mining, geothermal, civil, oil and gas, water and many other projects. Although, there are few commercial software capable of providing some useful functionalities fundamental for DFNE, their costs, closed code (black box) distributions and hence limited programmability and tractability encouraged us to respond to this rising demand with a new solution. This paper introduces an open source comprehensive software package for stochastic modeling of fracture networks in two- and three-dimension in discrete formulation. Functionalities included are geometric modeling (e.g., complex polygonal fracture faces, and utilizing directional statistics), simulations, characterizations (e.g., intersection, clustering and connectivity analyses) and applications (e.g., fluid flow). The package is completely written in Matlab scripting language. Significant efforts have been made to bring maximum flexibility to the functions in order to solve problems in both two- and three-dimensions in an easy and united way that is suitable for beginners, advanced and experienced users.

摘要： Herein, we describe engineered superparamagnetic iron oxide nanoparticles (IONPs) as platform materials for enhanced uranyl (UO22+) sorption and separation processes under environmentally relevant conditions. Specifically, monodispersed 8-25 nm iron oxide (magnetite, Fe3O4) nanoparticles with tailored organic acid bilayered coatings have been systematically evaluated and optimized to bind, and thus remove, uranium from water. The combined nonhydrolytic synthesis and bilayer phase transfer material preparation methods yield highly uniform and surface tailorable IONPs, which allow for direct evaluation of the size-dependent and coating-dependent sorption capacities of IONPs. Optimized materials demonstrate ultrahigh sorption capacities (>50% by wt/wt) at pH 5.6 for 8 nm oleic acid (OA) bilayer and sodium monododecyl phosphate (SDP) surface-stabilized IONPs. Synchrotron-based X-ray absorption spectroscopy shows that iron oxide core particle size and stabilizing surface functional group(s) substantially affect U(VI)-removal mechanisms, specifically the ratio of uptake via adsorption versus reduction to U(IV). Taken together, tunable size and surface functionality, high colloidal stability, and favorable affinity toward uranium provide distinct synergistic advantage(s) for the application of bilayered IONPs as part of the next-generation material-based uranium recovery, remediation, and sensing technologies.
