TL;DR: The present work highlights the potential for using amino-functionalized Fe(3)O(4)@SiO(2) magnetic nanoparticles as an effective and recyclable adsorbent for the removal of heavy metal ions in water and wastewater treatment.

TL;DR: The recovery of the adsorbed dye from bottom ash and de-oiled soya, have been found to be 85% and 99%, respectively, and column experiments indicate practical utility of the Adsorbents for eradicating hazardous dyes from effluents.

TL;DR: The adsorption performance of the materials bottom ash (BA), a power plant waste, and de-oiled soya (DOS), a soya bean industry waste for removal of crystal violet dye, has been investigated through batch and column experiments, which revealed that the adsorbent process is endothermic in nature.

TL;DR: The experimental results confirmed that triarylmethane dye Light Green SF (Yellowish) can be successfully removed and recovered from aqueous solutions economically and efficiently.

TL;DR: The proposed adsorbent for nickel removal is effective in terms of its performance and the FTIR results of algal biomass showed that biomass has different functional groups and these functional groups are able to react with metal ion in aqueous solution.

TL;DR: Thermogravimetric analysis shows that these silica microcapsules are degraded in two distinct steps, and have good thermal stability, and can achieve good phase-change performance, high encapsulation efficiency, and good antiosmosis property.

TL;DR: Various methods for synthesis of conducting polymer nanostructures and their applications in sensing materials are reviewed, focusing on hard-template, soft-template and other methods and the formation mechanism of Conducting polymer nanstructures by these methods.

TL;DR: A modified monomer addition model combined with aggregation model is proposed to analyze the formation mechanism of silica particles in Stöber process with high concentration of tetra-ethyl-orthosilicate up to 1.24 M.

TL;DR: Contrary to numerous claims in the literature, PNIPAM is not a hydrophobic material at temperatures above the LCST.

TL;DR: The results contradict the generally accepted view that basal plane surfaces of kaolinite carry a permanent negative charge due to minor substitution of Al(3+) for Si(4+) in the silica tetrahedral layer, and suggest some surface charge dependency of the two faces with respect to solution pH.

TL;DR: From the diffusion coefficient of water, which varied with increase in relative pressure, it is shown that water adsorbs first on primary sites, before formation of water clusters and their micropore filling which was a slow process.

TL;DR: Results indicate that, while ZFA had no affinity for BPA, the surfactant-modified ZFA (SMZFA) showed greatly enhanced adsorption capacity, and it is proposed that BPA anions interact strongly with the positively charged heads of HDTMA, with the two hydrophobic benzene rings of BPA pointing to the inside ofHDTMA bilayers.

TL;DR: It is concluded that the dispersion due to PCE strongly depends on the particle charge, which differs between colloids adsorbing and not adsorbed PCE, and leads to different forces acting between the particles.

TL;DR: The differences in surface properties, as shown by chemical, physicochemical and spectroscopic measurements would justify the differences in sensitivities to copper ions up-take between the two specimens.

TL;DR: The inhibition of low-carbon-steel corrosion in 1M HCl and 0.5M H(2)SO(4) by extracts of Dacryodis edulis (DE) was investigated using gravimetric and electrochemical techniques.

TL;DR: The prepared oxide is selective in photocatalysis; under UV light, its photocatalytic activity to degrade sunset yellow, rhodamine B, and methylene blue dyes is less than that of the undoped one.

TL;DR: Findings indicate that nano-goethite and nano-hematite are effective materials for Cu(2+) removal and, together with its photocatalytic activity, may be applied in the removal of heavy metal ions from aqueous streams.

TL;DR: The presence of zero-valent iron reactive species on the palygorskite surface strongly increases the decolourization capacity for methylene blue, and it is significant for providing novel modified clay catalyst materials for the removal of organic contaminants from waste water.

TL;DR: Positive correlations between cations desorbed and TC adsorbed, as well as TC adsorbbed and H(+) adsorBed, provided a first time evidence to confirm cation exchange as the main mechanism of TC uptake, even under neutral pH conditions.

TL;DR: It can be inferred from the study that fine tuning of the hydrogel synthetic parameters will enhance the possibilities of desired nano-product tailor made for particular applications.

TL;DR: It can be inferred from the adsorption results that physical adsor adaptation of ammonia on both MOFs dominated at ammonia pressures below 150 torr after which chemical reactions between ammonia and MOF frameworks take place.

TL;DR: The modified graphene exhibited good compatibility and interactions with the host PS matrix to form conducting PS films and the thermal properties of the PS were improved with the incorporation of graphene in the composite.

TL;DR: Based on the resulting hydrodynamic size distributions in the supernatant after sorption experiments, it could be shown that predominantly smaller particle aggregates oxide were sorbed onto E. coli, while S. cerevisiae were less affected by the presence of the nanoparticulate iron oxide.

TL;DR: Ordered mesoporous carbon was synthesized by a self-assembly technique and characterized with TEM, Raman spectroscopy, and nitrogen adsorption/desorption for its physical and pore textural properties to make it an ideal adsorbent for gas separation and purification applications.

TL;DR: The results of magnetic measurements and initial in vitro magnetic resonance imaging essays are presented for the pre- and post-surface modified nanoparticles, respectively and discussed in relation with their structure and microstructure.

TL;DR: It was found that the degree of silylation of Na-MMT increases with increasing the length of the aminosilane organic moieties, the overall aminoilane concentration, and temperature, and the same beneficial effects were observed on the silicate d-spacing.

TL;DR: A low-cost green and reproducible microbes (Lactobacillus sp. and Sachharomyces cerevisiae) mediated biosynthesis of CdS nanoparticles is reported and the surface plasmon resonance at 393 and 369nm respectively is revealed.

TL;DR: This featuring article summarizes the considerable progress in cell encapsulation into silica matrixes and highlights that functional living matters are very promising in the development of new eco-friendly processes.

TL;DR: The results show that the adhesion force between hydrates and solid surfaces was dependent on the surface material; solids with low surface free energy lead to the lowest adhesion forces.

TL;DR: It was found that both external and intraparticle diffusions contribute to the rate of removal of fluoride from the activated alumina-based adsorbents produced in the laboratory.
