This study explores the critical role of nonpolar ligand-solvent systems in modulating interparticle interactions colloidal nanocrystals, profoundly affecting stability and enabling precision self-assembly. A library 28 ligands with diverse molecular fragments─double bonds, branched chains, benzene rings, naphthalene rings─and four solvents was developed to investigate how fragment types positions affect ligand ordering attraction. Explicit solvent simulations enhanced sampling techniques...
Novel SiO2 nanoparticles (NPs) costabilized by a low-molecular-weight ligand (steric stabilization) and zwitterionic surfactant (electrostatic were developed for enhanced oil recovery purpose in sandstone reservoirs with high salinity elevated temperatures. According to our experiments, the proposed NPs not sensitive either monovalent or divalent cations, whose size remained around 10.0 nm API brine within 8 weeks at 25 °C 4 60 °C. Using reduced NP dosage required induce wettability...
Carbon dioxide (CO2) injection is a successful enhanced oil recovery (EOR) technology that being widely applied in North American fields. Studies have suggested CO2-based EOR technically possible the Middle Bakken Formation of Williston Basin Dakota. The swelling crude oil/CO2 mixture plays crucial role CO2 flooding process. Therefore, better understanding effect on and viscosity reduction critical for project unconventional reservoirs such as Formation. In this work, series n-alkane/CO2...
Nonionic surfactants are nonvolatile and benign chemicals widely used in the oil gas industry. However, their huge loss especially under high temperature salinity conditions has limited large-scale applications; thus, various additives were introduced to prepare compounded systems. This paper mainly focuses on nonionic surfactant–silica nanoparticle augmented Herein, an extensive series of adsorption tests related surfactant nanoparticles behavior change with presence was conducted, together...
An in situ potential-enhanced ion transport system based on the electrochemically switched permselectivity (ESIP) membrane was developed for effective removal of Ca2+ and Mg2+ from dilute aqueous solution. In this system, uptake/release target ions can be realized by modulating redox states ESIP membrane, continuously permselective separation through achieved tactfully applying a pulse potential combining with an external electric field. study, iron hexacyanoferrate...
A “top-down” tactic was offered to synthesize highly efficient electrocatalysts for the oxygen evolution reaction (OER), in which a CuO microcube supported Fe doped Co<sub>3</sub>O<sub>4</sub> nanosheet composite obtained using UPED method combined with thermal treatment.
Two major aspects of functional colloidal nanoparticles are their stability (dispersion) and controlled assembly into ordered structures. Simplifying as isotropically interacting spheres is unsuitable for small capped with hydrocarbon chain ligands in which the ligand-ligand interaction plays a prominent role processes. However, experimentally characterizing ligand shell structure solution presents significant challenges, computer simulations yield divergent results without effective...
Long-range ordered supercrystals (SCs) built up by colloidal nanocrystals (NCs) represent a class of novel metamaterials with unique collective properties. While great attention has been paid to the ligand-controlled assembly NCs, contribution inorganic core is considered limited because weak core-core interactions. Here, we report spontaneous Ag2S quantum dots (QDs) into three-dimensional SCs in solution, driven pronounced dipole-dipole Dielectric spectroscopy shows large permanent dipole...
Abstract A novel organic montmorillonite, which could act as both polycondensation catalyst of poly(ethylene terephthalate) (PET) and filler PET/clay nanocomposites, was prepared. Original montmorillonite first treated with different amounts poly(vinylpyrrolidone) (PVP), then intercalated by TiO 2 /SiO sol to gain catalytic activity. The acquired clay possessed excellent thermal stability would not degrade during the step. nanocomposites were prepared via in‐situ polymerization using...
Force fields based on the rigid ion model (RIM) have been developed to accurately predict various physical and chemical properties of salts water. However, combined use these models often fails solubility in To address this issue, several approaches, such as charge scaling or reparameterization, proposed. Nevertheless, methods require laborious reparameterization nonbonded force field parameters. In article, we propose a solute–solvent distance (SSSD) method improve predicting salt without...
CuI is an important semiconductor with a transparency in the visible light range. However, β phase structure at 643–673 K controversial. We used density functional theory (DFT) combined quasi-harmonic approximation (QHA) to investigate β-CuI. By analyzing relative energy, elastic and vibrational properties, finite-temperature free we ruled out previously proposed candidate (CS) space group R3̅m 2D bilayered stacking structure. DFT-QHA calculations showed that CSs P3̅m1 P3m1 groups, which...
