Special Issue Information

Dear Colleagues,

Nanomaterials have been at the center of interest for nearly decades as their contributions to different disciplines such as electronics, photonics and medicine are enormous. In contrast to nanomaterials, whose properties are inherent, nanostructures can be engineered to present unique optical and photonic properties by taking advantage of phenomena such as quantum confinement effects, localized plasmons, interference or effective media. Effects and applications include absorption, photoemission, scattering, nonlinear optics, ultrafast phenomena, photoconduction and photovoltaics, plasmonics, and lasing. Electronics are the introduction of vertical MOSFETs in addition to the planar ones to enable the multigate approach as well as the development of new tunneling, high-electron-mobility, and single-electron devices. Available applications for nanomaterials include wireless sensors, wide-bandgap semiconductors, superconductors, supercapacitors, medicine, magnetic materials, thin films, photovoltaic optics and photonics materials, flexible biomaterials, advanced materials, and hybrid materials to name just a few.

The goal of the present Special Issue is to attract academic and industrial researchers to further improve the properties of nanomaterials and propose new ideas for future applications and new technologies through continuous in-depth research on existing photonic and electronic nanocomposites. The Guest Editors invite authors to contribute original research articles and review articles covering the current progress on these materials. Potential topics include, but are not limited to:

  • Nanomaterials in medicine on biomedical devices;
  • Nanomaterial-based sensing technologies;
  • Magnetic nanomaterials and quantum materials;
  • Microwave, millimeter-wave and terahertz in biosensing;
  • Wide-bandgap materials and solid-state electronics;
  • Optoelectronics, electromagnetics and sensing on semiconductors;
  • Magnetic materials and electronic materials;
  • Electrocatalytic/photocatalytic materials.

Biogenic CoFe2O4 nanoparticles were prepared by co-precipitation and Hibiscus rosa sinensis plant leaf was used as a bio-reductant of the nanoparticle productions. The biosynthesized CoFe2O4 nanoparticles were characterized by XRD, FTIR, UV, VSM, and SEM via EDX analysis. The cubic phase of biosynthesized CoFe2O4 nanoparticles and their crystallite size was determined by XRD. The Co-Fe-O bonding and cation displacement was confirmed by FTIR spectroscopy. The presence of spherically-shaped biosynthesized CoFe2O4 nanoparticles and their material were confirmed by SEM and TEM via EDX. The super-paramagnetic behaviour of the biosynthesized CoFe2O4 nanoparticles and magnetic pulse was established by VSM analysis. Organic and bacterial pollutants were eradicated using the biosynthesized CoFe2O4 nanoparticles. The spinel ferrite biosynthesized CoFe2O4 nanoparticles generate radical and superoxide ions, which degrade toxic organic and bacterial pollutants in the environment. Full article

In this study, Fe2O3 powder was synthesized using the co-precipitation method from scrap iron, which was then treated with varying concentrations of copper. Afterwards, the modified Fe2O3 was reinforced in the PVC matrix by using the solution-casting method to synthesize PVC composite films, which were subjected to a UV-visible spectrophotometer, a Fourier transform infrared spectrophotometer, an X-ray diffractometer, and a thermal gravimetric analyzer to evaluate the optical, chemical, structural, and thermal properties. FTIR analysis reveals the formation of the composite through vibrational bands pertaining to both components present, whereas no significant changes in the XRD patterns of PVC were observed after the doping of modified iron oxide, which reveals the compatibility of fillers with the PVC matrix. The optical properties of the copper-doped iron oxide-PVC composites, including absorbance, refractive index, urbach energy, and optical as well as electrical conductivity are measured, and show an increase in optical activity when compared to the pure PVC compound. Moreover, the increased thermal stability of the synthesized composite was also observed and compared with conventional compounds, which, in accordance with all the other mentioned properties, makes the copper-dopped iron oxide-PVC composite an effective material for electronic, photonic, and optical device applications.
