Special Issue Information

Dear Colleagues,

In recent decades, there has been extensive scientific research on the various uses of nanoparticles in different applications: the environment, the production and storage of energy, construction, electronics, cosmetics, human health, medicine, etc. Nanoparticles (NPs) are relatively new class of materials that have one dimension less than 100 nm, and can be 0D, 1D, 2D, or 3D. Their very small size influences the physiochemical properties of a substance, e.g.,the curing properties, optical properties, surface area, adsorption and photocatalytic properties, biocompatibility, etc. Owing to such exceptional characteristics, these materials have gained the interest of researchers in multidisciplinary fields.

Nanoparticles enhance performance in application throughout the whole life cycle and maintain accountable performance. They minimize environmental impacts, increasing energy and material efficiency, and enhance the recyclability of materials. Nanoparticles synthesis should have a minimal environmental impact; itis frequently obtained by green technologies. As mentioned above, nanoparticles enhanceperformance in application throughout the whole life cycle and maintain accountable performance, but special attention must paid to avoid their pollution with nanoparticles.

It is generally acknowledged that a current challenge is the development of new materials for advanced applications. In fact, the problem of the development of new nanomaterials entailsa highly innovative and promising new approach, derived from the necessity of paying attention to water, air and soil remediation, energy obtaining, human health, medicine, etc.

The main objective of this Special Issue is to attract more attention to nanoparticles synthesis and its application among the international R&D community.

Synthesis and Applications of Nanoparticles is a special number dedicated to this class of materials. The domain of nanoparticles is continuously increasing because there are a lot of aspects that must be elucidated in this area.

For this Issue, many nanoparticles will be considered, including but not limited to inorganic materials, magnetic materials, adsorbents, membranes, photocatalysts, glasses, ceramics, concrete with nanoparticles, coating materials with nanoparticles, biopolymers, nano-insulation materials, carbon nanotubes, nano-hydroxyapatites, semiconductors, sensors, etc.

We kindly invite you to submit your research contribution, research article, communication, or review to this Special Issue.

Graphene has been regarded as one of the most promising two-dimensional nanomaterials. Even so, graphene was still faced with several key issues such as impedance mismatching and narrow bandwidth, which have hindered the practical applications of graphene-based nanocomposites in the field of microwave absorption materials. Herein, a series of Si-modified [email protected]3O4 composites were investigated and fabricated by a simple method. On one hand, the degree of defects in graphene carbon could be tuned by different silane coupling reagents, which were beneficial to enhancing the dielectric loss. On the other hand, the spherical Fe3O4 nanoparticles provided the magnetic loss resonance, which contributed to controlling the impedance matching. Subsequently, the electromagnetic absorption (EMA) properties of Si-modified [email protected]3O4 composites with poly(vinylidene fluoride-co-hexafluoropropylene) (PVDF-co-HFP) were investigated in this work. As a result, the Si(2)[email protected]3O4/PVDF-co-HFP composite exhibited the excellent EMA performance in the range of 2–18 GHz. The maximum reflection loss (RLmax) reached −32.1 dB at 3.68 GHz at the thickness of 7 mm and the effective absorption frequency bandwidth for reflection loss (RL) below −10 dB was 4.8 GHz at the thickness of 2 mm. Furthermore, the enhanced absorption mechanism revealed that the high-efficiency absorption performance of Si(2)[email protected]3O4/PVDF-co-HFP composite was attributed to the interference absorption (quarter-wave matching model) and the synergistic effects between Si(2)[email protected]3O4 and PVDF-co-HFP. This work provides a potential strategy for the fabrication of the high-performance EMA materials. Full article
