“…Nevertheless, the most used technique for CNTs growth is chemical vapor deposition (CVD) due to its scalability for commercial production and the possibility of obtaining long CNTs (Lengths achieved with CVD are around 1mm [9], while lengths measured from PECVD are between 6 to 8 μm) [10]. The CVD process consists in introducing a hydrocarbon gas, such as 𝐶𝐻 4 into a tubular reactor.…”

Carbon nanotubes can be synthesized using various techniques. This work aims to study the experimental process of growing carbon nanotubes via plasma-enhanced chemical vapor deposition (PECVD). Additionally, the study aims to calibrate the reactor and develop a LabVIEW code to introduce water into the process, enabling a water-assisted PECVD procedure. The obtained samples are evaluated through the analysis of SEM images and Raman spectra.

“…These materials are distinguished by their exceptional optical properties, small size, unique electronic characteristics, and high reactivity in comparison to bulk materials [1]. A variety of methods are employed to synthesize nanoparticles, including combustion [2], co-precipitation [3], green [4], plasma-enhanced chemical vapor deposition [5], hydrothermal [6], microwave [7], sol-gel methods [8], and chemical reduction methods [9][10][11][12][13].…”

We herein report a direct and facile hydrothermal method for the preparation of zero-valent silver nanoparticles using a mixture of ascorbic acid/starch as a reducing agent. The average crystallite size of the prepared Ag0 nanoparticles was ca. 46.7 nm. The zero-valent silver nano-products were characterized by using FT-IR, FE-SEM, and XRD analyses. In addition, this work shows an improved synthesis of graphene oxide nanoparticles. The average crystallite size of the prepared graphene-oxide nanoparticles was ca. 6.0nm. The graphene oxide nanoparticles were also characterized by using FT-IR, FE-SEM, and XRD analyses.
