Special Issue Information

Dear Colleagues,

Nanocomposites have been considered valuable podia for developing advanced applications in various fields with improved performance. Nanocomposites are a class of nanomaterials wherein one or more phases, present in nano-sized dimensions (zero dimension, one dimension, and two dimensions), are embedded in ceramic, metal, or polymer materials. Nanocomposites differ from conventional composite materials due to the nanoscale dimensions of the filler phase and the exceptionally high surface-to-volume ratio of this phase. It often results in unique mechanical, thermal, electrical, optical, or catalytic properties controlled by factors such as local chemistry, mobility, morphology, or crystallinity. In addition, nanocomposites often offer a combination of several properties, making them even more attractive as multifunctional materials in the future, with potential applications in aerospace, healthcare, energy materials, sensors, and other systems.

This Special Issue, entitled Multifunctional Nanocomposites: Facile Scalable Synthesis and Advanced Applications, aims to present a collection of articles on recent developments in the field of the facile synthesis of nanocomposites using environmentally friendly and scalable methods along with novel and improved applications. This Special Issue will focus on the synthesis, processing, properties, modelling, and applications of various nanocomposites. Original research articles, reviews, letters to the editor, and short communications are welcome.

Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Materials is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Abstract
Gold nanoparticles (GNP) were bio-fabricated utilizing the methanolic extract of the endophytic isolate Aspergillus terreus. The biosynthesised gold nanoparticles (GNP023) were characterised using UV-visible spectroscopy (UV-Vis); transmission electron microscopy (TEM), Fourier-transform nfrared spectroscopy (FTIR) and X-ray diffraction (XRD) studies. The bio-fabricated GNP023 [...] Read more.
Gold nanoparticles (GNP) were bio-fabricated utilizing the methanolic extract of the endophytic isolate Aspergillus terreus. The biosynthesised gold nanoparticles (GNP023) were characterised using UV-visible spectroscopy (UV-Vis); transmission electron microscopy (TEM), Fourier-transform nfrared spectroscopy (FTIR) and X-ray diffraction (XRD) studies. The bio-fabricated GNP023 displayed a sharp SPR peak at 536 nm, were spherically shaped, and had an average size between 10–16 nm. The EDX profile confirmed the presence of gold (Au), and XRD analysis confirmed the crystalline nature of GNP023. The antimicrobial activity of GNP023 was investigated against several food-borne and phytopathogens, using in vitro antibacterial and antifungal assays. The maximum zone of inhibition was observed for S. aureus and V. cholera at 400 μg /mL, whereas inhibition in radial mycelial growth was observed against Fusarium oxysporum and Rhizoctonia solani at 52.5% and 65.46%, respectively, when challenged with GNP023 (200 μg/mL). Moreover, the gold nanoparticles displayed significant antioxidant activity against the ABTS radical, with an IC50 of 38.61 µg/mL, and were non-toxic when tested against human kidney embryonic 293 (HEK293) cells. Thus, the current work supports the application of myco-synthesised gold nanoparticles as a versatile antimicrobial candidate against food-borne pathogens. Full article
