“…The Raman results have been compared with the growth CNTs in a unique flow rate to ensure the effect of the transitive gas flow on the growth process. Accordingly, two main peaks are found at 1348 cm −1 and 1577 cm −1 ; these peaks correspond to the D and G bands, respectively [ 28 ]. The I D / I G ratio suggests that the crystallinity of the synthesized CNTs under varying flow rates is identical to those grown under a fixed flow rate [ 29 ].…”

Among the wide range of renewable energy sources, the ever-increasing demand for electricity storage represents an emerging challenge. Utilizing carbon nanotubes (CNTs) for energy storage is closely being scrutinized due to the promising performance on top of their extraordinary features. In this work, well-aligned multilayer carbon nanotubes were successfully synthesized on a porous silicon (PSi) substrate in a fast process using renewable natural essential oil via chemical vapor deposition (CVD). Considering the influx of vaporized multilayer vertical carbon nanotubes (MVCNTs) to the PSi, the diameter distribution increased as the flow rate decreased in the reactor. Raman spectroscopy results indicated that the crystalline quality of the carbon nanotubes structure exhibits no major variation despite changes in the flow rate. Fourier transform infrared (FT-IR) spectra confirmed the hexagonal structure of the carbon nanotubes because of the presence of a peak corresponding to the carbon double bond. Field emission scanning electron microscopy (FESEM) images showed multilayer nanotubes, each with different diameters with long and straight multiwall tubes. Moreover, the temperature programmed desorption (TPD) method has been used to analyze the hydrogen storage properties of MVCNTs, which indicates that hydrogen adsorption sites exist on the synthesized multilayer CNTs.

“…One of which is the carbon nanotube (CNT), first reported by S. Iijima in the 1990s [27]. Since then, much research has gone on to understand its physical properties [4], [5], [6], primary synthesis techniques [28], and characterisation in their existence as single layered, singlewalled CNTs (SWCNTs) or as two or more coaxial layered multi-walled CNTs (MWCNTs) [29]. Over time, the extraordinary physical, thermal, and electrical transport properties of CNTs have been made known to the scientific community and have begun to pique the interest in industrial applications.…”

circuit designs that have to incorporate miniaturisation to its components and EM compliance methods [3]. Therefore, there is a need for a miniaturised, high performance EM isolation technique to mitigate or even circumvent this issue. This report aims to use CNTs to improve the EM isolation of signal traces on electronic circuit boards and reduce the amount of conventional isolation required for proper EM compliance, thus, reducing the required board real estate and allowing for future size reduction in circuits.
