Special Issue Information

Dear Colleagues,

During the last decades, the world-wide power consumption has grown almost 15-fold. The most intensely exploited primary power sources are petroleum (30%), coal (20%), natural gas (20%), and nuclear fuel (6%). This has caused the increase in the carbon dioxide release into the atmosphere 4.5 times during the last 50 years, which gives rise to considerable ecological problems. Besides that, the obtained estimates of the conventional energy source resources demonstrate that the oil and gas resources are hardly sufficient for 100 years.  Thus, on the one hand, one of the basic problems of the modern power industry is to find alternative renewable power sources (e.g., hydrogen) and efficiently increase their share in the general power consumption. On the other hand, it is necessary to develop strategies for more efficient power storage, transmission, and conversion.  This is of particular interest owing to active development of the Internet of Things solutions, which require designing innovative low-power machines, systems, and devices.

In this view, graphene and other 2D Layered based nanomaterials that are characterized by unique atomic and electronic structures offer a broadest diversity of solutions and strategies in the field of energy applications. Chemical and physical properties of these materials may be efficiently designed, engineered and tuned for each specific energy application by using the controllable synthesis procedure, structure modification by chemical and physical methods, introducing impurities or creating defects, and also by combining them in hybrid structures.

The area of interest of the Special Issue is very broad. We expect contributions on the following topics:

  • 2D materials
  • layered materials
  • 2D carbon-based nanocomposite and nanostructures
  • graphene and graphene derivatives (GO, rGO, etc.)
  • carbon nanotubes and their derivatives
  • carbon nanofibers
  • 2D layered hybrid nanomaterial-based films
  • transition metal dichalcogenides (MX2)
  • WS2
  • MoS2
  • transition metal carbides
  • transition metal nitrides
  • transition metal carbonitrides (MXenes)
  • silicene
  • germanene
  • stanene
  • van der Waals heterostructures
  • interfaces
  • 2D layered-based composites

We examine the performance of a finite-time, endoreversible Otto heat engine with a working medium of monolayer or multilayered graphene subjected to an external magnetic field. As the energy spectrum of multilayer graphene under an external magnetic field depends strongly on the number of layers, so too does its thermodynamic behavior. We show that this leads to a simple relationship between the engine efficiency and the number of layers of graphene in the working medium. Furthermore, we find that the efficiency at maximum power for bilayer and trilayer working mediums can exceed that of a classical endoreversible Otto cycle. Conversely, a working medium of monolayer graphene displays identical efficiency at maximum power to a classical working medium. These results demonstrate that layered graphene can be a useful material for the construction of efficient thermal machines for diverse quantum device applications. Full article

Results from studying the effect of an applied electric voltage on the Raman spectrum of graphene deposited on a lithium niobate crystal substrate with a ferroelectric domain structure are presented. The use of the principal component method for data processing in combination with correlation analysis made it possible to reveal the contribution to the change in the spectra associated with the linear deformation of the substrate due to the inverse piezoelectric effect. An effect of the graphene coating peeling was found. Furthermore, bending deformations of the graphene coating associated with the presence of a relief on the substrate were found. An analysis of the change in the spectra of graphene under the application of an electric voltage made it possible to determine the height of this relief. Full article

Graphene derivatization to either engineer its physical and chemical properties or overcome the problem of the facile synthesis of nanographenes is a subject of significant attention in the nanomaterials research community. In this paper, we propose a facile and scalable method for the synthesis of thiolated graphene via a two-step liquid-phase treatment of graphene oxide (GO). Employing the core-level methods, the introduction of up to 5.1 at.% of thiols is indicated with the simultaneous rise of the C/O ratio to 16.8. The crumpling of the graphene layer upon thiolation without its perforation is pointed out by microscopic and Raman studies. The conductance of thiolated graphene is revealed to be driven by the Mott hopping mechanism with the sheet resistance values of 2.15 kΩ/sq and dependable on the environment. The preliminary results on the chemiresistive effect of these films upon exposure to ethanol vapors in the mix with dry and humid air are shown. Finally, the work function value and valence band structure of thiolated graphene are analyzed. Taken together, the developed method and findings of the morphology and physics of the thiolated graphene guide the further application of this derivative in energy storage, sensing devices, and smart materials.

Herein, we describe a study of the phenomenon of field-induced electron emission from thin films deposited on flat Si substrates. Films of Mo with an effective thickness of 6–10 nm showed room-temperature low-field emissivity; a 100 nA current was extracted at macroscopic field magnitudes as low as 1.4–3.7 V/μm. This result was achieved after formation treatment of the samples by combined action of elevated temperatures (100–600 °C) and the electric field. Morphology of the films was assessed by AFM, SEM, and STM/STS methods before and after the emission tests. The images showed that forming treatment and emission experiments resulted in the appearance of numerous defects at the initially continuous and smooth films; in some regions, the Mo layer was found to consist of separate nanosized islets. Film structure reconstruction (dewetting) was apparently induced by emission-related factors, such as local heating and/or ion irradiation. These results were compared with our previous data obtained in experiments with carbon islet films of similar average thickness deposited onto identical substrates. On this basis, we suggest a novel model of emission mechanism that might be common for thin films of carbon and refractory metals. The model combines elements of the well-known patch field, multiple barriers, and thermoelectric models of low-macroscopic-field electron emission from electrically nanostructured heterogeneous materials.
