Article 3. Roles Of the Debye Length and Skin Depth in The Characterization of Space Charge Interactions in Semiconductor Nanoparticles
The third article is reported by the Zhijing Hu et al. from Keysight Technologies, USA, Illinois Institute of Technology, USA, Qorvo, USA and Kunming University of Science and Technology, China. This article describes the non-degenerate semiconductor nanoparticles with bulk plasma frequency in the terahertz frequency range are of substantial current interest for device and sensing applications in that part of the electromagnetic spectrum. The penetration of electromagnetic field in a material containing mobile charges is governed by two length scales, namely the Debye length and the skin depth. Here, examination of the spectra of charge, field, and current distributions allows for the identification of the influence of particle size, Debye length and skin depth on space charge interactions in a semiconductor nanoparticle.

Article 4. Antifungal Activity of Iron-Gold and Cobalt-Gold Co-Doped Zinc oxide Nanoparticles
The fourth article of the issue describes the antifungal activity of nanoparticles (NPs). Here, nanoparticles (NPs) have been synthesized via poly-ethylene glycol assisted route. The average crystallite size of NPs was estimated from X-ray diffraction results and UV absorption spectra. The antifungal activity of synthesized NPs was found against four postharvest pathogenic fungi like Aspergillus niger, Aspergillus flavus, Rhizopus microsporus and Pencillium sp. The doping of iron and gold in zinc oxide nanoparticles enhances the zone of inhibition for the fungal pathogens compared to pure zinc oxide nanoparticles. Here, antifungal activity of nanoparticles was higher when compared with standard antibiotic mycostatin.
