Polymer-clay composites were designed to adsorb selenium from water. The highest adsorption efficiency was obtained for chitosan-montmorillonite composites. These composites were characterized by XRD, zeta potential, and FTIR measurements. Adsorption isotherms of selenate on the composite, on Al-oxide and on Fe-oxide were in good agreement with the Langmuir model, yielding a somewhat higher cap...

The present experiment describes a synthesis process of composites based on graphene oxide, which was tested as a carrier for composites of metalor metalloid-based nanoparticles (Cu, Zn, Mn, Ag, AgP, Se) and subsequently examined as an antimicrobial agent for some bacterial strains (Staphylococcus aureus (S. aureus), methicillin-resistant Staphylococcus aureus (MRSA) and Escherichia coli (E. co...

A simple method to obtain homogeneous sub-monolayer coverage of metal oxide and chalcogenide nanocrystals onto porous oxide supports is described. Quantitative nanoparticle coverage was probed using photonic macroporous oxide supports. Composites of nanocrystals of TiO₂, Fe₃O₄ or CdS dispersed onto macroporous SiO₂ or ZrO₂ all show a predictable linear shift in the photonic stop band position.

Rare-earth containing oxide nanocomposites are prepared of porous GaP and GaAs templates in a controlled fashion. The initial porous GaP and GaAs networks are replaced by GaPO4 and Ga2O3 structures, respectively, during annealing at temperatures from 500 to 900 C. The impregnation of Eu and Er lanthanides from EuCl3:C2H5OH and ErCl3:C2H5OH solutions results in the formation of lanthanide contai...

The extensive oxygen-group functionality of single-layer graphene oxide proffers useful anchor sites for chemical functionalization in the controlled formation of graphene architecture and composites. However, the physicochemical environment of graphene oxide and its single-atom thickness facilitate its ability to undergo conformational changes due to responses to its environment, whether pH, s...

Homogeneous graphene-MOF composites based on a 2D pillared-bilayer MOF (Cd-PBM), {[Cd4(azpy)2(pyrdc)4(H2O)2]·9H2O}n (azpy = 4,4'-azopyridine, pyrdc = pyridine-2,3-dicarboxylate), have been synthesized, using both graphene oxide (GO) and benzoic acid functionalized graphene (BFG). The composites GO@Cd-PBM and BFG@Cd-PBM demonstrate growth of the 2D nano-sheets of MOF on the graphene surface. Whi...

The processing conditions for preparing well dispersed silica-graphene nanoplatelets and silica-graphene oxide nanoplatelets (GONP) composites were optimized using powder and colloidal processing routes. Fully dense silica-GONP composites with up to 2.5 vol% loading were consolidated using spark plasma sintering. The GONP aligned perpendicularly to the applied pressure during sintering. The fra...

A mechanochemical synthetic method of preparing LiCoO2 coated by MOF-derived metal oxide composites is introduced. Mono-dispersed ZrO2 and Al2O3 are applied as protection layers. These composites show 148 mA h g(-1) at a current density of 2325 mA g(-1) and excellent thermal stability (55 °C).
