“…However using certain carbon feedstocks that decompose at lower temperatures, plasma decomposition techniques, and catalyst engineering, <500 °C growth temperatures can be achieved under certain conditions. [ 74 ] Some studies have shown that using microwave synthesis, catalyst nanoparticles can be selectively heated to the required CNT growth temperature, while keeping the rest of the substrate at lower temperatures <150 °C. [ 75 ] Metal nanoparticles are selectively heated because they can absorb the microwave frequencies and heat up, while the rest of the substrate is microwave transparent or reflective.…”

Carbon nanotube (CNT) devices and electronics are achieving maturity and directly competing or surpassing devices that use conventional materials. CNTs have demonstrated ballistic conduction, minimal scaling effects, high current capacity, low power requirements, and excellent optical/photonic properties; making them the ideal candidate for a new material to replace conventional materials in next-generation electronic and photonic systems. CNTs also demonstrate high stability and flexibility, allowing them to be used in flexible, printable, and/or biocompatible electronics. However, a major challenge to fully commercialize these devices is the scalable placement of CNTs into desired micro/nanopatterns and architectures to translate the superior properties of CNTs into macroscale devices. Precise and high throughput patterning becomes increasingly difficult at nanoscale resolution, but it is essential to fully realize the benefits of CNTs. The relatively long, high aspect ratio structures of CNTs must be preserved to maintain their functionalities, consequently making them more difficult to pattern than conventional materials like metals and polymers. This review comprehensively explores the recent development of innovative CNT patterning techniques with nanoscale lateral resolution. Each technique is critically analyzed and applications for the nanoscale-resolution approaches are demonstrated. Promising techniques and the challenges ahead for future devices and applications are discussed.

“…48,49 Therefore, the in situ generation of CO, CH 4 , and CO during pyrolysis also contributes to the formation of the carbon nanotubes. [56][57][58] During heat treatment, the metallic Co nanoparticles are rapidly formed in the top part. In the meantime, the released CH 4 , CO, and H 2 work together with the Co nanoparticles to guide the formation of carbon nanotubes.…”

A gradient carbon-metal hybrid component can be manufactured by thermopyrolysis of metal-organic framework powder. The non-uniformly distributed carbonaceous vapor and uniformly dispersed Co nanoparticles are essential for generating the gradient carbon monolith. This monolith exhibits good mechanical strength and high catalytic activity, and thus can be directly utilized as an electrode for a Mg/H 2 O battery to generate electricity from seawater. The assembled battery shows power density comparable with that of a battery with Pt as the electrode.

“…С момента открытия углеродных нанотрубок (УНТ) [1] было показано, что они обладают уникальными механическими [2], температурными [3], химическими [4,5] и электрическими [6,7] свойствами. Возможность формирования переплетенных, а также вертикально ориентированных массивов с УНТ, обладающих малым радиусом острия и высоким аспектным отношением, делают их перспективными объектами для создания дисплеев [8,9], источников рентгеновского излучения [10], устройств вакуумной микро-и наноэлектроники [11,12].…”

The results of experimental studies of the influence of the growth temperature and the thickness of the catalytic layer on the geometric and structural parameters of carbon nanotubes (CNTs) are presented. It is shown that the use of a TiN-based sublayer makes it possible to provide a low resistivity during the direct growth of CNTs on a conducting contact. It was found that for the formation of the best piezoelectric response, it is necessary to form the most defective CNTs. It is shown that the degree of defectiveness of CNTs can be controlled during their growth. A relationship has been established between the geometric and structural parameters of CNTs that affect the piezoelectric response. The potential applicability of CNTs for the creation of nanopiezotronic devices (nanogenerators, energy nanocarvesters) on their basis is shown.
