TL;DR: By optimizing system composition and homogenization conditions, the spontaneous emulsification method was able to form VE-loaded nanoemulsions with small mean droplet diameters and low polydispersity indexes (PDI<0.13).

TL;DR: The enhanced crystallinity, reduced layer thickness, high surface area, large pore volume, enlarged band gap, and reduced number of defects were responsible for the activity enhancement of g-C3N4 sample treated for a longer time.

TL;DR: GT-Fe NPs were successful in removing MCB from wastewaters, and the possible Fenton-like oxidative mechanism of MCB was proposed, indicating that Fe(2+) and Fe(3+) leached from GT- Fe NPs nanoparticles and consequently reduced the formation of iron sludge.

TL;DR: The overarching goal of this feature article is to review the recent developments in the field of drug delivery specifically involving colloidal lyotropic liquid crystalline dispersions, and the types of therapeutic compounds and medical imaging agents that can be incorporated as well as their methods of preparation.

TL;DR: The high surface area graphene nanosheets as dispersed phase in polymeric nanocomposites showed significant improvement in thermal stability and electrical conductivity.

TL;DR: The increase in CO(2) adsorption capacity after chemical activation is closely related to the narrower pore size distribution rather than the total or micropore volume and specific surface area.

TL;DR: Mn3O 4 exhibited excellent catalytic stability in several runs, demonstrating that Mn3O4 is a promising catalyst alternative to toxic Co3O3 for water treatment.

TL;DR: This report reports on the adsorption performance of calcium alginate and Ca-Alg2 with encapsulated graphene oxide (Ca- Alg2/GO) gel bead adsorbents for the successful removal of Cu(2+) ions from aqueous solution.

TL;DR: In the two- component solution, both competitive adsorption and positive synergy of chelation between metal ions occurred and the novel adsorbent showed higher affinity toward Cd(II) than in the one-component solution, and the BiLangmuir isotherm model was well fitted to the experimental data suggesting the surface heterogeneity of the novel Adsorbent.

TL;DR: The careful examination of high resolution Fe 2p, O 1s, and P 2p spectra before and after phosphate sorption allows the characterization of the modifications occurring onto the ferrihydrite surface.

TL;DR: Kaolinite-supported nanoscale zero-valent iron was successfully synthesized as a multifunctional composite and used for the degradation of crystal violet (CV) and the application of K-nZVI to treat wastewater showed the removal efficiency higher than 99.9%.

TL;DR: Oleogels and oleogel-based emulsions prepared using shellac as a structurant showed good stability over 4 months of storage, and the thermo-reversible, hysteresis, thixotropic and shear thinning properties of oleogs were evaluated by comparing rheological data obtained from rotational and oscillatory measurements.

TL;DR: The zinc oxide-reduced graphene oxide (RGO) nanocomposites were greenly synthesized by one-step hydrothermal reaction with ZnCl2 and graphite oxide (GO) as precursors without extra reductant to achieve photo-degradation of Rhodamine B and photo-reduction of CO2 under the illumination of simulated solar light at ambient temperature.

TL;DR: As-prepared membranes with high abrasion resistance and comparable air permeability showed fascinating filtration efficiency and low pressure drop performance for 300-500 nm sodium chloride aerosol particles, suggesting their use as a promising medium for variety of potential applications in air filTration.

TL;DR: TheTiO2-RGO exhibited an improved photocatalytic performance in the reduction of Cr(VI) under visible light irradiation, with a maximum removal of 86.5% vs 54.2% due to the increased light absorption intensity and wavelength range as well as the reduction in electron-hole pair recombination in TiO2 with the addition of RGO.

TL;DR: Results of this study suggest that CuO nanoparticles show potential for developing a simple process for field applications to remove arsenic from water.

TL;DR: It was established that the adsorption process obeyed the pseudo-second-order kinetic model and the activation parameters were determined, namely the activation energy, the change of entropy, and Gibbs free energy for the formation of activated complex from the reagents.

TL;DR: A novel glucose biosensor was further fabricated by immobilizing glucose oxidase (GOD) into MBA terminated Ag@AuNPs-GO nanocomposite film (MBA-Ag@ auNps-GO) and applied successfully for the determination of glucose in blood samples.

TL;DR: The enhanced photocatalytic activity can be attributed to more effective charge transportations and separations arisen from the strong chemical bonding between BiOI and graphene, the high dye adsorption performance, and the increased light absorption.

TL;DR: This novel magnetic hybrid nanomaterial derived from GO/LDH hybrid demonstrates great potential in the applications of water treatment and Magnetism characterization proves the ferromagnetic property of rGO/Ni/MMO hybrid.

TL;DR: The proposed technique in this study provides an efficient approach for synthesis of monodisperse hollow or core-shell calcium alginate microcapsules with large cavity or encapsulated lipophilic drugs, chemicals, and nutrients.

TL;DR: It is shown that the concentration of Cl(-) ions in the gold precursor solution plays a critical role in the stability of the bi-metallic sol and the structure of the deposited silver shell.

TL;DR: Highly fluorescent papain stabilized gold nanoclusters (NCs) have been synthesized through a simple wet chemical route and the sensing strategy is also highly selective against the various potential interference ions.

TL;DR: In this article, the main mechanism of boron uptake appeared to be anion exchange, which was confirmed by powder X-ray diffraction (XRD) measurements, and the composition and orientation of the interlayer bors ions could be identified with reasonable certainty by applying a number of characterisation techniques.

TL;DR: The results of static experiments and dynamic experiments indicated that the adsorption of phosphorus onto sponge iron was more apt to chemical combination, but zeolite wasMore apt to electrostatic attraction or ion-exchange.

TL;DR: Assessment of the mechanisms of Sb(III) and S b(V) adsorption on natural red earth (NRE), a naturally occurring iron coated sand, at various pHs and Sb loadings revealed that sorption occurs through the formation of bidentate mononuclear and binuclear complexes.
