Summary: In this study, a sensitive detection method against the toxic pesticide endosulfan was proposed using multiwalled carbon nanotubes (MWCNT). The detection limit for endosulfan was found to be 0.184 ppt in standard buffer. The fabricated immunosensor showed good cross reactivity with other pesticides and can be used for successful detection of endosulfan in the agricultural sector.

Summary: Heteroatoms, particularly nitrogen, in multiwalled carbon nanotubes significantly influence their distribution and physicochemical properties. X-ray photoelectron spectroscopy revealed maximal nitrogen content in the second high-temperature zone of the reactor, with predominance of pyrrolic-N doping. The increase in I-D/I-G ratio in Raman spectroscopy indicates the presence of defective graphitic material.

Summary: A new hybrid composite of activated carbon/multiwalled carbon nanotubes-ZnFe2O4 has been prepared for supercapacitor electrode material with excellent capacitance and cycle stability. The addition of metal oxides, specifically zinc ferrite, enhances the capacitance and performance of the composite. Various tests and characterizations have confirmed the reliability and high-performance potential of the composite for supercapacitor applications.

Summary: The electrocatalytic properties of multiwalled carbon nanotubes (MWCNTs) on the oxygen reduction reaction (ORR) in aqueous base have been studied at the single entity level. It has been shown that the electroactive surface functionality facilitates significant electrocatalysis, resulting in the formation of peroxide at lower potentials compared to bare carbon macroelectrodes and carbon nanotube modified electrodes.

Summary: Four types of nanocellulosic materials with different functional groups were used to disperse multiwalled carbon nanotubes, resulting in composite electrodes with excellent stability and electrochemical properties in different electrolytes. Anionic fibrillar nanocellulosic composites showed strong electrostatic and physical enrichment effects, while denser crystalline composites did not exhibit such behavior. This study provides insights for developing customizable nanocellulose/carbon nanomaterial hybrid platforms for various electrochemical applications.

Summary: In this study, waste-derived carbon materials and their composites were used for electrochemical sensing of caffeic acid. The hydrothermal process was employed to prepare an activated carbon composite, which was then electrochemically modified to enhance the electrochemical signal for caffeic acid. The prepared sensor was successfully applied for real-time electrochemical quantification of caffeic acid in commercial samples.

Summary: The study found that multiwalled carbon nanotubes had a potential impact on soil organisms, especially with higher sensitivity in nematodes. Contamination by CNTs significantly affected the dynamics and diversity of soil fauna and microbial communities, potentially leading to long-term consequences for soil functioning and nutrient cycling.

Summary: Single-entity electrochemistry measurements were used to compare the electrocatalysis of the oxygen reduction reaction (ORR) by multiwalled carbon nanotubes (MWCNTs) or amino-functionalized multiwalled carbon nanotubes (MWCNTs-NH2). The evidence showed that the electroactive surface oxygen functionality played the most important role in the catalysis process, not the nitrogen content.

Summary: Above a critical diameter, carbon nanotubes collapse into flattened forms, leading to unique Raman spectra changes. The presence of edge cavities and curvature changes near the edges activate a D band despite overall continuity in the structure. The differing perspectives of chemists and physicists on defects in carbon structures may lead to confusion for researchers in nanotechnologies.

Summary: High-pressure carbon monoxide (HiPCO) synthesized single-walled carbon nanotubes (SWCNTs) were heat treated at high temperatures, resulting in an increase in diameter and the formation of double-, triple-, and multi-walled carbon nanotubes (MWCNTs). Most MWCNTs were found to have an odd number of walls, in accordance with the mechanism of SWCNT bundle coalescence.
