“…The 1245 cm −1 shoulder is related to transpolyacetylene (TPA) and its strength increases with increasing hydrogen content in a‐C:H film . The peaks above 1700 cm −1 are sidebands associated with precursors used in the deposition process and indicate the existence of carbon chains of different lengths (C‐chains) …”

Patterning of nanocomposites by conventional lithography processes is problematic due to the different physical properties of matrix and filler. Direct laser interference patterning (DLIP) promises rapid micromachining of virtually any material with subwavelength resolution. A control of intense laser light modifies the filler particle size distribution in nanocomposite films. Herein, DLIP of periodic patterns with half‐pitch <1 μm in reactive magnetron‐sputtered hydrogenated amorphous diamond‐like carbon nanocomposite thin films with embedded silver nanoparticles (DLC:Ag) is demonstrated. Periodic patterns of regularly repeating areas with modified size distributions of silver nanoparticles are obtained by a variation of fluences and number of pulses of 515 nm wavelength femtosecond laser. Depending on the silver content in nanocomposite films, nanoparticle size distributions are either bimodal (for 14.1 at% Ag containing films) or unimodal (7.9 at%) with effective average diameters shifting from 13 to 69 nm, depending on the laser processing parameters. The importance of localized surface plasmon absorption and localized field enhancement at the DLC–Ag interface for lowering the ablation threshold of DLC:Ag nanocomposites below 6 mJ cm−2 at 1000 pulses is demonstrated. This is at least four times lower than the threshold for pure DLC obtained using the same DLIP setup.

“…The analysis of a 2D-ordered linear-chain carbon-based nanomatrix that can be performed with Raman spectroscopy goes beyond just simple chemical classification and refers to the category of vibrational spectroscopy [ 46 , 47 , 48 , 49 ]. The Raman spectroscopy analyzes a sample through the molecular vibration excitation and the subsequent decrypting of this vibrational interaction.…”

A recently proposed, game-changing transformative energetics concept based on predictive synthesis and preprocessing at the nanoscale is considered as a pathway towards the development of the next generation of high-end nanoenergetic materials for future multimode solid propulsion systems and deep-space-capable small satellites. As a new door for the further performance enhancement of transformative energetic materials, we propose the predictive ion-assisted pulse-plasma-driven assembling of the various carbon-based allotropes, used as catalytic nanoadditives, by the 2D-ordered linear-chained carbon-based multicavity nanomatrices serving as functionalizing nanocarriers of multiple heteroatom clusters. The vacant functional nanocavities of the nanomatrices available for heteroatom doping, including various catalytic nanoagents, promote heat transfer enhancement within the reaction zones. We propose the innovative concept of fine-tuning the vibrational signatures, functionalities and nanoarchitectures of the mentioned nanocarriers by using the surface acoustic waves-assisted micro/nanomanipulation by the pulse-plasma growth zone combined with the data-driven carbon nanomaterials genome approach, which is a deep materials informatics-based toolkit belonging to the fourth scientific paradigm. For the predictive manipulation by the micro- and mesoscale, and the spatial distribution of the induction and energy release domains in the reaction zones, we propose the activation of the functionalizing nanocarriers, assembled by the heteroatom clusters, through the earlier proposed plasma-acoustic coupling-based technique, as well as by the Teslaphoresis force field, thus inducing the directed self-assembly of the mentioned nanocarbon-based additives and nanocarriers.

Особый интерес представляют азотированные пленки, полученные при помощи импульсноплазменного осаждения, которые обладают хорошими механическими и трибологическими свойствами [11]. Разнообразие применений азотированных углеродных пленок и различные эффекты, обусловленные внедрением азота, влекут за собой необходимость исследования их структуры и роли азота в ее формировании.…”

Carbon films were synthesized by pulse-plasma ion-assisted graphite sputtering in the atmosphere of argon-nitrogen mixture. The samples were studied by Raman spectroscopy, electron diffraction and XPS. According to the obtained data, nitrogen efficiently incorporates into the material structure, which leads to the formation of oriented graphite nanoclusters, which fraction reduces with ion assistance energy increase.
