Special Issue Information

Dear Colleagues,

Graphene is a two-dimensional layered material composed of sp2 hybridized carbon atoms and combines exceptional thermal and electrical conductivity with lightweight, flexibility, and strength. This nanomaterial has enormous potential to enhance the performance of polymeric materials and make them suitable for a multitude of high-demanding applications in the transportation, energy, optoelectronic, water treatment, and biomedical sectors, to name a few. Graphene can be used in its pristine form, as well as functionalized forms (starting from graphite oxide or graphene oxide). Moreover, other carbon-based nanomaterials, such as carbon nanotubes, graphite, fullerene, and carbon fiber, are seen as “graphene derivatives”. Graphene and other carbon-based materials are often employed as reinforcing agents for polymers, ceramics, metal, steel, aluminum, and other types of alloys.

This Special Issue aims to expand the state of knowledge on the use of graphene (in both pristine and functionalized forms), and other carbon-based nanomaterials to reinforce a large variety of polymers (synthetic, bio-based, thermoplastics, thermosets, amorphous or semi-crystalline), as well as ceramics, metal, steel, aluminum, and other types of alloys. The specific focus will be on the improvement of mechanical, physical, chemical, thermal, electrical, and structural/morphological properties of the composites, which can be particle-reinforced, fiber-reinforced, and laminated composites.

Research papers, as well as reviews, are welcome.

Carbon quantum dots (CQDs) are emerging novel nanomaterials with a wide range of applications and high biocompatibility. However, there is a lack of in-depth research on whether CQDs can cause acute or long-term adverse reactions in aquatic organisms. In this study, two different types of CQDs prepared by ammonia citrate and spermidine, namely CQDAC and CQDSpd, were used to evaluate their biocompatibilities. In the fish embryo acute toxicity test (FET), the LD50 of CQDAC and CQDSpd was about 500 and 100 ppm. During the stage of eleutheroembryo, the LD50 decreased to 340 and 55 ppm, respectively. However, both CQDs were quickly eliminated from embryo and eleutheroembryo, indicating a lack of bioaccumulation. Long-term accumulation of CQDs was also performed in this study, and adult zebrafish showed no adverse effects in 12 weeks. In addition, there was no difference in the hatchability and deformity rates of offspring produced by adult zebrafish, regardless of whether they were fed CQDs or not. The results showed that both CQDAC and CQDSpd have low toxicity and bioaccumulation to zebrafish. Moreover, the toxicity assay developed in this study provides a comprehensive platform to assess the impacts of CQDs on aquatic organisms in the future. Full article
