TL;DR: Results from UV-vis absorption study, Electron microscopy, Fourier transform infrared spectroscopy and X-ray photoelectron spectroscopic suggest that the improved photoactivity is due to a decrease in band gap energy, an increased light absorption in visible light region and possibly an enhanced electron-hole separation efficiency as a result of effective interfacial electron transfer between TiO2 and g-C3N4 of the g-N4/TiO2 composite film.

TL;DR: The findings suggest that both the reduction as well as stabilization of nanoparticles were achieved by the flavonoids and phenolics.

TL;DR: Robust performance of nZVI@MG arises from the formation of micro-nZ VI-graphene/nZVI-Fe3O4 batteries and strong adsorption capability of broad graphene sheet/Fe3 O4 surfaces.

TL;DR: Enhanced photocatalytic performance of In2S3/g-C3N4 heterojunctions could be attributed to its wide absorption in the visible region and efficient electron-hole separation and superoxide radicals and holes are suggested to play a critical role in RhB degradation.

TL;DR: The results indicate that the adsorption process is fitted to Langmuir model and the composites with lower density of MNPs represent better adsorbents ability, and its kinetics follows pseudo-second order rate equation.

TL;DR: It is suggested that pore-size distribution of electrode materials, especially the meso/microporosity ratio, should be optimized for the removal of targeted ions by CDI and well characterized to conduct more precise CDI modeling.

TL;DR: Quantitative chemical calculations revealed that the photoactivity enhancement is strongly dependent on the active role played by the frontier orbital energy levels of dye molecules and a probable correlation of "structure-activity" relationship was established.

TL;DR: The present manuscript focus on the synthesis of surface hydroxyl group enriched titanium dioxide nanotube (TNT) by hydrothermal method for preferential adsorption of methylene blue (MB) dye, which demonstrated that enhancement in the surface area of TNT and higher number of hydoxyl group on the surface of TNT.

TL;DR: Sorption kinetics of carbamazepine on graphene oxide powders was rapid and reversible with alcohol washing, consistent with π-π interactions, and only the highest surface area graphene oxide out-performed GAC and MWCNTs.

TL;DR: It was found that Na3Cit added into the reaction solution greatly influenced the formation and size dimension of the nano-sheets, furthermore determined assembling of the laurustinus shaped micro-particles.

TL;DR: The composite rapidly and efficiently removed As(V), Cr(VI), and also Congo red dye, from aqueous solutions suggesting their usefulness for removal of toxic materials from wastewater.

TL;DR: Photocatalytic degradations of azo dye, pesticide and antibiotic in aqueous solutions were performed and compared by using pure ZnO and Zn O/TiO2 composite catalysts in a self-supporting plate form to indicate their potentiality in extended applications.

TL;DR: These superparamagnetic CIONs are resistant to protein adsorption under physiological medium and exhibit good colloidal stability, magnetization and cytocompatibility with cell lines and can be used as a contrast agent in MRI as well as localized heat activated killing of cancer cells.

TL;DR: The coated samples could maintain their superhydrophobicity, oil absorption capacity and oil/water selectivity after harsh mechanical damage, 90 days of immersion in oils and ten cycles of absorption-desorption, which makes it very promising for practical oil absorption.

TL;DR: The ultrasonic bath method even with low intensity has a fundamental role in the synthesis of graphene oxide nanosheets and it is relatively fast, simple, cost-effective and efficient as compared to the classical method.

TL;DR: Microwave heating helps to overcome several disadvantages associated with thermal heating and results in improved particle characteristics and there is thus the potential for new opportunities in the development of colloidal carriers.

TL;DR: The quercetin conjugated superparamagnetic Fe3O4 nanoparticles are validated for in-vitro analysis of breast cancer cell lines for chemotherapy and show significant changes in cellular morphology observed through fluorescent microscopy.

TL;DR: In this article, the shape, size and rheological properties of nanoscale polymer microspheres were investigated using scanning electron microscopy (SEM), dynamic lighting scattering (DLS) and HAAKE rheometer experiments.

TL;DR: It is proposed that both electrostatic interactions and partitioning process are involved in the adsorption mechanisms of Orange II dye onto HCZ and suggest a multi-layer physi-sorption process.

TL;DR: Chemical evolved investigation revealed that graphitic-like embedded basic nitrogen groups are generated from bridged and terminal amines of urea formaldehyde resin from thermal carbonization and KOH activation treatment, which is responsible for the enrichment of CO2 capacity by chemical adsorption mechanism.

TL;DR: A novel reversible pseudo-first order kinetic model was developed and applied to correlate this newly reported adsorption-desorption phenomenon and the physical and chemical properties of chitosan were studied and presented in terms of its surface and structural properties.

TL;DR: Fe/S doped granular activated carbon catalysts could significantly enhance the removal rate of OG as compared to persulfate alone and PS/GAC and the catalytic capacity was also enhanced by S doping; the existence of FeS2(S(-)) for sulfur element verified the assumption that the doped S element promoted the electron transfer between the Persulfate species and iron oxide at the interface.

TL;DR: The preliminary results show that the new compound TCFCS can act as a mixed-type metal anticorrosion inhibitor in some extent; its inhibition efficiency is 92% when the concentration was 60 mg/L.

TL;DR: It was found that the nitrogen groups making the as-prepared NGs exhibited remarkably enhanced electrochemical performance when used as electrode materials in supercapacitors.
