This report describes the fabrication of a novel microfluidics nanobiochip based on a composite comprising of nickel oxide nanoparticles (nNiO) and multiwalled carbon nanotubes (MWCNTs), as well as the chip's use in a biomedical application. This nanocomposite was integrated with polydimethylsiloxane (PDMS) microchannels, which were constructed using the photolithographic technique. A structura...

Removal of toxic heavy metals from aquatic environments has become a major concern due to environmental problems and the potential hazards risks posed by them. Nowadays, adsorption method as one most effective methods removing pollutants attracted increasing attention among chemists researchers. However, challenges is design develop more adsorbents well prepare them via greener safer approaches...

Potentially, the toxicity of multiwalled carbon nanotubes (MWCNTs) can be reduced in a safe-by-design strategy. We investigated if genotoxicity and pulmonary inflammation MWCNTs from same batch were lowered by a) reducing length b) introducing COOH-groups into structure. Mice administered: 1) long pristine MWCNT (CNT-long) (3.9 μm); 2) short CNT (CNT-short) (1 3) modified with high ratio (CNT-C...

the interaction between some heavy metal ions such as of pb(ii), cd(ii) and cu(ii) ions from aqueous solution adsorbed by single walled carbon nanotube (swcnts) and carboxylate group functionalized single walled carbon nanotube (swcnt-cooh) surfaces were studied by atomic absorption spectroscopy. the effect of contact time, ph, initial concentration of ion, ionic strength and temperature on the...

Graphene oxide (GO) was synthesized using Sri Lankan naturally available graphite and Fe3O4 nanoparticles were successfully incorporated fabricating magnetically separable GO/Fe3O4 nanocomposite. The nanocomposites characterized by X-ray diffractometry (XRD), Scanning electron microscopy (SEM), FT-IR spectroscopy. Crystalline phases of GO identified XRD patterns, while the presence functional g...

A novel acid-base HT-PEM consisting of PI-COOH and OPBI was prepared. The OPBI-50PI-COOH composite membrane delivered superior cell performance durability under low PA uptake due to the continuous hydrogen bond network between PI-COOH.

Abstract Herein, we report the synthesis, characterization, and application of TiO 2 /ZnO La-doped ZnO nanocomposites for detection degradation studies Malachite Green (MG). were synthesized by reflux hydrothermal methods, respectively, characterized UV–visible spectroscopy, X-ray diffraction, Fourier transform infrared scanning electron microscopy, energy-dispersive analysis. A glassy carbon e...

The effect of carboxyl groups on the redox activity polyluminol-carbon nanotube composites was studied. Carboxyl were selected due to their known contributions toward surface wettability and pseudocapacitance while often present naturally derived low-cost porous carbons. Density functional theory (DFT) predicted energetically favoured bonding a significantly reduced band gap between luminol car...

The interaction between some heavy metal ions such as of Pb(II), Cd(II) and Cu(II) ions from aqueous solution adsorbed by single walled carbon nanotube (SWCNTs) and carboxylate group functionalized single walled carbon nanotube (SWCNT-COOH) surfaces were studied by atomic absorption spectroscopy. The effect of contact time, pH, initial concentration of ion, ionic strength and temperature on the...
