We have demonstrated near-edge X-ray absorption fine structure (NEXAFS) spectroscopy as a particularly useful and effective technique for simultaneously probing the surface chemistry, surface molecular orientation, degree of order, and electronic structure of carbon nanotubes and related nanomaterials. Specifically, we employ NEXAFS in the study of single-walled carbon nanotube and multi-walled...

Heat conduction in multi-walled carbon nanotubes (MWNTs) was studied using non-equilibrium molecular dynamics simulations. This research focuses on the effects of the multi-wall structure of the MWNTs on the heat conduction. The results show that the thermal conductivity of a MWNT is almost the same as that of the corresponding single-walled carbon nanotubes (SWNTs) rather than much smaller as ...

Submit Manuscript | http://medcraveonline.com could be used as a nutrient carrier for macro and micro elements that may reduce their higher concentrations which are usually used. Carbon nanotubes applications in agriculture showed very promising results [4]. It takes an important role due to its competitive mechanical, electrical, thermal and chemical properties [3]. Single and multi-walled CNT...

Background and purpose: Continuous input of antibiotics to the environment causes many problems such as antibiotic resistance in pathogenic microorganisms. Therefore, researchers are aiming to find solutions to reduce antibiotics in hospital effluents and polluted waters. Amoxicillin is an antibiotic which is widely used to treat infections. Due to inappropriate use it enters the wastewater and...

The analysis of the structure and chemical state polyaniline/multi-walled carbon nanotube interface layer was carried out using both methods Near Edge X-Ray Absorption Fine Structure Photoelectron Spectroscopy. An photoelectron spectra showed an increase in content covalently bound chlorine, which may be due to functionalization nanotubes during polymer synthesis. spectrum shows two states chlo...

Gold nanoparticles (AuNPs) were assembled with high density onto multi-walled carbon nanotubes, which were functionalized with zwitterionic poly(imidazoliumsulfonate). The AuNP/zwitterionic CNT hybrids exhibited decent electrocatalytic activity in oxygen reduction reaction as the AuNP-based catalysts.
