Special Issue Information

Dear Colleagues,

This Special Issue publishes original research articles, review articles, and short communications on the application possibilities and the latest developments in 2D metal carbides and nitrides (MXenes). MXenes, owing to their chemical composition, structure, and unique properties, offer great application possibilities. This Special Issue aims to reflect the application possibilities and indicate new trends in the development of these materials.

Articles focusing on methods of obtaining a surface modification, research on catalytic properties, biotechnological applications, and energy storage are invited. Articles describing the production of metal, ceramic, and polymer composites, in which MXene has been used as the reinforcing phase, are also welcome, as well as papers on experimental research and modeling of the structure and mechanical properties, the thermal stability of MXene, and composites with their addition.

The aim of the research was to characterize the soldering alloy type Zn-Mg-Sr and direct the soldering of SiC ceramics with Cu-SiC-based composite. It was investigated whether the proposed composition of the soldering alloy was appropriate for soldering those materials at the defined conditions. For the determination of the solder melting point, TG/DTA analysis was applied. The Zn-Mg system is of the eutectic type with a reaction temperature of 364 °C. The effect of strontium on the phase transformation was minimal, owing to its lower content. The microstructure of the soldering alloy type Zn3Mg1.5Sr is formed of a very fine eutectic matrix containing segregated phases of strontium—SrZn13 and magnesium—MgZn2 and Mg2Zn11. The average tensile strength of the solder is 98.6 MPa. The tensile strength was partially increased by solder alloying with magnesium and strontium. The SiC/solder joint was formed due to the distribution of magnesium from the solder to the boundary with the ceramics at the formation of a phase. Owing to soldering in air, oxidation of the magnesium took place and the oxides formed were combined with the silicon oxides that remained on the surface of the ceramic material—SiC. Thus, a strong bond based on oxygen was obtained. An interaction between the liquid zinc solder and the copper matrix of the composite substrate took place at the formation of a new phase—γCu (Cu5Zn8). The shear strength was measured on several ceramic materials. The average shear strength of the combined SiC/Cu-SiC joint fabricated with Zn3Mg1.5Sr solder was 62 MPa. When soldering similar ceramic materials mutually, a shear strength of as much as around 100 MPa was observed. Full article

This article presents an attempt to determine the effect of the MXene phase addition and its decomposition during sintering with the use of the spark plasma sintering method on mechanical properties and residual stress of silicon carbide based composites. For this purpose, the unreinforced silicon carbide sinter and the silicon carbide composite with the addition of 2 wt.% of Ti3C2Tx were tested. The results showed a significant increase of fracture toughness and hardness for composite, respectively 36% and 13%. The numerical study involving this novel method of modelling shows the presence of a complex state of stress in the material, which is related to the anisotropic properties of graphitic carbon structures formed during sintering. An attempt to determine the actual values of residual stress in the tested materials using Raman spectroscopy was also made. These tests showed a good correlation with the constructed numerical model and confirmed the presence of a complex state of residual stress. Full article

This paper discusses the effects of the environment and temperature of the Ti3C2 (MXene) oxidation process. The MXene powders were annealed at temperatures of 1000, 1200, 1400, 1600, and 1800 °C in argon and vacuum using a Spark Plasma Sintering (SPS) furnace. The purpose of the applied annealing method was to determine the influence of a high heating rate on the MXene degradation scheme. Additionally, to determine the thermal stability of MXene during the sintering of SiC matrix composites, SiC–C–B–Ti3C2 powder mixtures were also annealed. The process parameters were as follows: Temperatures of 1400 and 1600 °C, and pressure of 30 MPa in a vacuum. Observations of the microstructure showed that, due to annealing of the SiC–C–B–Ti3C2 powder mixtures, porous particles are formed consisting of TiC, Ti3C2sym, and amorphous carbon. The formation of porous particles is a transitional stage in the formation of disordered carbon structures. Full article

Inks printing is an innovative and practicable technology capable of fabricating the next generation of flexible functional systems with various designs and desired architectures. As a result, inks printing is extremely attractive in the development of printed wearables, including wearable sensors, micro supercapacitor (MSC) electrodes, electromagnetic shielding, and thin-film batteries. The discovery of Ti3C2Tx in 2011, a 2D material known as a MXene, which is a compound composed of layered nitrides, carbides, or carbonitrides of transition metals, has attracted significant interest within the research community because of its exceptional physical and chemical properties. MXene has high metallic conductivity of transition metal carbides combined with hydrophilic behavior due to its surface terminated functional groups, all of which make it an excellent candidate for promising inks printing applications. This paper reviews recent progress in the development of 2D MXene inks, including synthesis procedures, inks formulation and performance, and printing methods. Further, the review briefly provides an overview of future guidelines for the study of this new generation of 2D materials. Full article
