Carbon nanomaterials are effective adsorbents for water treatment. This study examines natural organic matter (NOM) removal from drinking water with combined coagulation processes using single-walled carbon nanotubes (SW...

A semi-analytical formalism for the optical properties of a metal-insulator-metal periodic nanostructure using coupled-mode theory is presented. This structure consists in a dielectric layer in between two metallic layer...

Ultrafine pure and Mn-doped SnO2 nanoparticles (NPs) were synthesized via the microwave technique. They were produced using tin chloride and hexamethylenetetramine at the molar ratio of 1:20. The concentrations of Mn in ...

In the present work, the synergistic effect of multiwalled carbon nanotubes and glycidyl polyhedral oligomeric silsesquioxanes on the compression after impact behaviour of multifunctional carbon fibre–reinforced epoxy ...

Raw TiO2 nanoparticles were prepared using the hydroly‐ sis of TiCl4. The nanoparticles were subjected to a surface treatment in diluted sulphuric acid and, subsequently, calcined at different temperatures. Then, a typ...

Graphite was exfoliated to graphene by tip sonic using sodium cholate as a surfactant in the presence of Millipore water as a medium. The use of water as a solvent for exfoliation purposes is very important due to its en...

The influence of Au nanorods coated with a silica layer on the photoluminescence (PL) of CdTe quantum dots (QDs) was investigated. The Au nanorods were prepared using a seed-mediated method. They were coated with a silic...

This paper reports on miniaturized hydrogen sensing platforms, exploring several means of fabricating nano‐ structured films and evaluating their sensing characteris‐ tics. Palladium-sputtered nanoporous organosilica...

This study reported the synthesis of aqueous dispersions of highly stable silver nanoparticles (AgNPs) using gamma radiation with gum acacia (GA) as the stabilizing and protecting agent. The formation of nanosized silver...

DCM is classified among the most hazardous atmospheric pollutants and therefore, the development of safe methods for the disposal of residual DCM is of great importance. Activated carbon- supported catalysts containing p...

A fluorescence resonance energy transfer (FRET)- based aptamer biosensor (aptasensor) for sensitive determination of adenosine triphosphate (ATP) was developed. The energy donor and acceptor were 5′-carboxyfluorescein ...

Low nano-SiO2 loaded nylon 6 (PA6) nanocomposites were readily produced via in situ polymerization. The effect of surface-modified functional groups of nano-SiO2 on the interfacial structure and properties of nylon 6/SiO...

In this work, we produced nickel oxide nanostructures that show high electrochemical capacitive behaviour, using fungus - one of the most common life forms in nature. Cladosporium cladosporioides fungi are particularly a...
