Special Issue Information

Dear Colleagues,

Following the successful first edition of this Special Issue of Crystals, we are pleased to announce that submissions to its second edition, entitled " Advanced Technologies in Graphene-Based Materials (2nd Edition)", are now being accepted.

Graphene-based materials, such as monolayer graphene, carbon nanotubes, graphene oxide and reduced graphene oxide, as well as functionalized versions of all these, are an essential part of innovative technologies relevant to the development of many fields of industry. The use of graphene-based nanostructures or their nanocomposites with specific physicochemical properties could promote technological progress in electronics, catalysis, biosensors, biomedicine, and many other areas that can improve the quality of human life. Due to the broad and diverse range of potential applications of graphene-based materials, the development of new synthesis and functionalization pathways, reliable characterization, and a better understanding of the structure-property relationships in materials are rightfully considered to be critical scientific issues. Scientific research dealing with the synthesis, functionalization, and characterization of graphene-based materials will contribute positively to the development of future technologies.

The scope of this Special Issue of Crystals, entitled “Advanced Technologies in Graphene-Based Materials”, includes, but is not limited to, the preparation and functionalization routes, characterization, and application of graphene-based materials, as well as their nanocomposite materials that are important in the fields of electronics, energy storage, and biomedicine, among others. We would like to invite researchers to submit work in the form of an original research article or a review paper related to the new synthesis methods of graphene-based nanomaterials, and their prospects in the different fields of application.

This study investigated the effects of incorporating reduced-graphene-oxide-coated alumina (Al2O3–RGO) nanoparticles and unmodified graphene oxide (GO) onto the microstructure as well as the mechanical properties of Al2O3/TiB2 matrix ceramic materials. The microstructure observation revealed that, compared with GO addition, the addition of Al2O3–RGO nanoparticles significantly improved RGO dispersion in the ceramic materials and reduced defects such as pores caused by graphene agglomeration. In addition, the uniformly dispersed RGO nanosheets were interwoven with each other to form a three-dimensional grid structure due to grain growth and the disappearance of pores during sintering, which increased the contact area and interface-bonding strength between the RGO and ceramic matrix. According to the results of microstructure observation and analysis, the good interfacial strength not only facilitated load transfer from the ceramic matrix to the RGO but also induced the fracture mechanism of the RGO, which consumes more fracture energy than the traditional toughening mechanism. The results of mechanical properties analysis showed that the hardness, flexural strength, and fracture toughness of the obtained ATB–RG3.0 ceramic material was measured at 19.52 GPa, 1063.52 MPa, and 9.16 MPa·m1/2, respectively. These values are 16.82%, 27.92%, and 26.87% higher than those of the ceramic material with 3.0 vol.% GO. Full article
