The hole transport properties of poly(2-methoxy, 5-(2'-ethyl-hexoxy)-p-phenylene vinylene) (MEH-PPV) blended with acid oxidized multiwall carbon nanotubes (COOH-MWCNTs) were investigated in a diode configuration using the time-of-flight (TOF) photocurrent method. While the room temperature hole mobility in pure MEH-PPV films was non-dispersive with positive field dependent mobility, MEH-PPV:COO...

background and objective: multi-walled carbon nano tubes (mwcnts) as an important element of nanosciences have a remarkable absorption in the region of nir window (650-900 nm) which can overcome the limitations of deep treatment in photothermal therapy. to disperse mwcnts in water, it is proposed to attach carboxylated functional group (-cooh) to mwcnts in order to increase dispersivity in wate...

Commercial production of nanoparticles (NP) has created a need for research to support regulation of nanotechnology. In the current study, microbial biofilm communities were developed in rotating annular reactors during continuous exposure to 500 μg L(-1) of each nanomaterial and subjected to multimetric analyses. Scanning transmission X-ray spectromicroscopy (STXM) was used to detect and estim...

Background and Objective: Multi-walled Carbon Nano Tubes (MWCNTs) as an important element of nanosciences have a remarkable absorption in the region of NIR window (650-900 nm) which can overcome the limitations of deep treatment in photothermal therapy. To disperse MWCNTs in water, it is proposed to attach carboxylated functional group (-COOH) to MWCNTs in order to increase dispersivity in wate...

This investigation shows the results of a coupled numerical and experimental study on solidification melting spherical capsules development correlations for time with parameters that impact complete phase change nanofluids water without polyethylene glycol inside plastic capsules. Experiments included different configurations capsule diameters, external temperature, initial temperature material...

A disubstituted quaterpyridine based cobalt complex non-covalently tethered to multiwalled carbon nanotube (MWCNT) substrate, forming a hybrid catalyst, Co-qpyCOOH/CNT, catalyzed the conversion of CO2 CO under aqueous conditions. At an optimal and uniform loading, it exhibited remarkable catalytic activity, near-exclusive selectivity, high stability towards formation CO. mere cathodic potential...

Polymer-multiwalled carbon nanotube (MWCNT) nanohybrids, which differ in surface charge have been synthesized to study the bioelectrocatalysis of adsorbed cellobiose dehydrogenase (CDH) from Phanerochaete sordida on gold electrodes. To obtain negatively charged nanohybrids, poly(3-amino-4-methoxybenzoic acid-co-aniline) (P(AMB-A)) was covalently linked to the surface of MWCNTs while modificatio...

In this paper, we propose a simple procedure to obtain multi-walled carbon nanotubes (MWCNTs) decorated with TiO2–Ag nanoparticles (MWCNT–TiO2–Ag). The MWCNTs were via combined functionalization –OH and –COOH groups polymer-wrapping technique using poly(allylamine)hydrochloride (PAH). TiO2-modified Ag synthesized the Pechini method mixture of acetylacetonate-modified titanium (IV) isopropoxide ...

An amine-functionalized multiwalled carbon nanotube (MWCNT) was prepared for use as a basic heterogeneous catalyst the conversion of Cocos nucifera (coconut) oil and Hibiscus cannabinus (kenaf) to biodiesel. The 3-aminopropyltrimethoxysilane (3-APTMS) chosen form an amine-reactive surface bind with hydroxyl (−OH) carboxyl (−COOH) groups oxidized MWCNT. Silanization took place using green modifi...
