Summary: In this study, new treatments based on different decorated multi-walled carbon nanotubes (MWCNTs) have been proposed for improving wood properties. The treated wood materials showed improved stability, water absorption and mechanical properties compared to untreated wood. The most effective treatment was using MWCNTs decorated with zinc oxide (ZnO) solution applied by brushing.

Summary: In this study, multi-walled carbon nanotubes with different functionalities were chemically modified with N1-(3-trimethoxysilylpropyl)diethylenetriamine (DETASi) to enhance CO2 adsorption/separation properties. Among the functionalized samples, COOH-modified MWCNT showed the highest CO2 adsorption capacity after DETASi modification. Additionally, the selectivity for CO2/N2 separation was improved after DETASi grafting reaction.

Summary: By chemically modifying multi-walled carbon nanotubes (MWNTs) and improving their solubility, a PDHT-g-MWNTs material that is soluble in organic solvents is obtained. An Al/PDHT-g-MWNTs/ITO electronic device was fabricated by sandwiching a PDHT-g-MWNTs film between Al and ITO electrodes, exhibiting nonvolatile rewritable memory behavior with symmetrical turn-on/off voltages, long retention time, and durability for switching cycles. These findings provide important insights into the development of carbon nanotube-based materials for information storage.

Summary: The study presented a sensitive detection method for nitroaromatic explosives using a GC/MWCNTs/PEI electrode coated with gold nanoparticles. The method successfully detected TNT, DNT, 2,4-DNP, PA, and tetryl in a linear range, with detection limits ranging from 15 μg L-1 to 135 μg L-1. This method was also validated against the reference LC-MS method for analyzing explosives in soil samples.

Summary: Carbon materials with varied structural and textural properties were used as adsorbents to remove estrogen hormones from aqueous solutions. The adsorption process was found to be influenced by surface mesoporosity, rather than specific surface area or surface oxygen groups. The high adsorption efficiency and capacity of mesoporous carbon cryogel and multi-walled carbon nanotubes make them effective adsorbents for rapid removal of estrogen hormones from water.

Summary: In this study, multi-walled carbon nanotubes (MWCNTs) were modified using polydopamine (PDA) to improve their dispersity, resulting in enhanced tensile and tear strength in Natural Rubber Latex Composites. The physical adsorption of PDA did not alter the structure of MWCNTs, and the surface modification of PDA significantly improved the dispersion of MWCNTs in the composite material. Additionally, a proposed reinforcement mechanism of MWCNTs in natural rubber matrix composites was detailed and supported by experimental results.

Summary: In this study, multi-walled carbon nanotubes (MWCNTs) with strong visible fluorescence were synthesized via oxidation and amination. The oxygen-containing surface functional groups contributing to fluorescence emission were found, and novel carbon nanoclusters with a diameter of 20-30 nm were formed at the tips of MWCNTs. The fluorescent MWCNTs exhibited distinct excitation-wavelength dependence, pH response, and temperature sensitivity.

Summary: Novel films of nitrogen-doped multi-walled carbon nanotubes (N-MWCNTs) were prepared by chemical vapor deposition and decorated with 14.0 nm gold nanoparticles (AuNPs). Electron microscopy analysis showed that AuNPs decoration did not affect the bamboo-shaped configuration of N-MWCNTs. Electrochemical response of the fabricated composite films (N-MWCNTs/AuNPs) towards dopamine oxidation was studied in real pig serum, demonstrating slightly enhanced sensitivity compared to unmodified N-MWCNTs. The findings suggest that AuNPs significantly improve the electrochemical response and detection ability of N-MWCNTs, making them a powerful analytical sensor for dopamine analysis in real serum samples.
