“…This rearrangement could provide an orderly charge transfer path, resulting in a higher electrical conductivity, with a faster response time 29 . Similar results were also observed in the synthesis of carbon nanotube arrays from Ferrocene, where the G/D band intensity ratio demonstrated a decline with the increase of heat treatment temperature in a certain range 26 . In this study, the sample carbonized at 900 °C was considered for further processing.…”

Extrusion processing of carbon tubes can be problematic due to their poor interfacial interactions with polymeric matrices. Surface chemical modification of carbon tubes can be utilized to create bonding sites to form networks with polymer chains. However, chemical reactions resulting in intermolecular primary bonding limit processability of extrudate, since they cause unstable rheological behaviour, and thus decrease the stock holding time, which is determinative in extrusion. This study presents a method for the synthesis of carbon microtubes with physically modified surface area to improve the filler and matrix interfacial interactions. The key concept is the formation of a nanogrooved topography, through acoustic cavitation on the surface of processing fibres. The effect of nanogrooving on roughness parameters is described, along with the role of surface modified carbon tubes on rheological behaviour, homogeneity, and coherency of extrudate. The measurements showed that nanogrooving increases the surface area of carbon microtubes, as a result, die swelling of the extrudate is reduced. Furthermore, after solidification, the mechanical strength of composite is reinforced due to stronger interactions between nanogrooved carbon tubes and polymer matrix.

“…The ratio of the G band (I G ) to the D band (I D ) intensities reveals the crystalline arrangement of carbonized cellulose at different temperatures. Similar analysis has been used to evaluate the crystalline structure of carbon materials with different heat treatment temperatures 26 , 27 . As seen in Fig.…”

“…Raman spectrum has a wide range of applications for both qualitative and quantitative chemical and biological analyses because of its high selectivity and low absorption of aqueous solution [6,7]. Also, it can be used in identification the carbon nanomaterials such as graphene and carbon nanotubes [8][9][10]. This is due to the Raman spectrum provides information about the rotational and vibrational transitions modes of the molecule.…”

In this work, nanoporous Cr thin film was designed by a novel method for the detection of toxic heavy metals based on surface-enhanced Raman spectroscopy. Nanoporous Cr thin film has been deposited on an aluminum substrate through a developed etching/DC electrodeposition technique of the hexagonal porous anodic alumina (PAA) template/Cr nanoparticles, respectively. The structures and morphologies of the fabricated samples were investigated by different characterization tools. The FE-SEM illustrates nanoporous Cr particles of rough surfaces and different sizes are formed on the Al substrate. Also, there are ultrafine Cr nanoparticles covered the surface of the Cr nanoporous film that can act as hot-spots during the detection of heavy metal ions. The proposed sensor established high selectivity at low concentrations between different heavy metal ions (Pb 2+ , Hg 2+ , Cd 2+ ). Also, it showed excellent selectivity towards Pb 2+ over the other metal ions. Hence, this category of sensors could be applied for sensitive determining of Pb 2+ , Hg 2+ , Cd 2+ in contaminated water.

Hierarchical TiN nanotube mesh (HTNM) is prepared by calcining TiO2 nanotube mesh (TONM) in NH3 flow where the TONM is fabricated by electrochemical anodic oxidation of Ti mesh. Calcining temperature affects not only phase composition but also morphology of the HTNM, which further affects its optical absorption and solar water evaporation conversion efficiency (η). The η can reach to 85.36% under 2.5 kW m−2 simulated solar irradiation because HTNM efficiently utilizes solar light. Moreover, it can be reutilized because of its stabilities of the phase composition and nanostructure during the measurements of solar water evaporation performance.
