Topic Information

Dear Colleagues,

Various advanced nanomaterials have been developed using versatile technologies including electrodeposition, electrospray, electrospinning, chemical vapor deposition, hydrothermal/solvothermal reactions and atom layer deposition. These nanomaterials are generally defined as materials with at least one dimension in the nanometer range (usually below 100 nm). In a broad sense, bulk materials assembled using low-dimensional nanomaterials can also be referred to as nanomaterials. In addition, porous materials comprising abundant nanopores with diameters below 100 nm can also be classified as nanomaterials. As such, these materials exhibit extremely high surface area to volume ratios, and the reduction in dimensionality leads to quantum confinement effects that engender unique physical/chemical properties that are substantially different from their bulk counterparts. The use of nanomaterials is crucial in energy storage/conversion devices such as lithium ion batteries, electrochemical capacitors, hybrid ion capacitors, solar cells and flow batteries due to their exceptional cycling stability and high charge storage capacity. Nanomaterials can be utilized as stable (photo)electrocatalysts in various reactions including (sea)water splitting, the oxygen reduction reaction, the CO2 reduction reaction, the N2 reduction reaction and the urea oxidation reaction. Nanomaterials also have shown promise regarding their application in wastewater treatment as adsorbents to remove/separate dyes, heavy metal ions, antibiotics and oil from water. This Topic aims to provide an overview of recent advances and future prospects regarding the contribution of nanomaterials and related technologies to sustainable development; therefore, we welcome original articles, perspectives, and review articles. We invite authors to submit their latest experimental and theoretical contributions that address the following areas of interest:

  • Synthesis and characterization of nanomaterials;
  • Advances in analytical tools (in situ, ex situ, operando);
  • Applications as (photo)electrocatalysts;
  • Applications in energy conversion;
  • Applications in energy storage;
  • Applications in wastewater treatment.

CuM and AgM (M = Cr, Fe) catalysts were synthesized, characterized, and evaluated in methane reforming with CO2 with and without pretreatment under a H2 atmosphere. Their textural and structural characteristics were evaluated using various physicochemical methods, including XRD, B.E.T., SEM-EDS, XPS, and H2-TPR. It was shown that the nature of the species has a significant effect on these structural, textural, and reactivity properties. AgCr catalysts, presenting several oxidation states (Ag0, Ag+1, Cr3+, and Cr6+ in Ag, AgCrO2, and AgCr2O4), showed the most interesting catalytic performance in their composition. The intermediate Cr2O3 phase, formed during the catalytic reaction, played an important role as a catalytic precursor in the in situ production of highly dispersed nanoparticles, being less prone to coke formation in spite of the severe reaction conditions. In contrast, the AgFe catalyst showed low activity and a low selectivity for DRM in the explored temperature range, due to a significant contribution of the reverse water–gas shift reaction, which accounted for the low H2/CO ratios.

Abstract
A novel ophthalmic delivery system utilizing levofloxacin-loaded, preservative-free, nanofiber-based inserts was investigated. Polyvinyl alcohol (PVA) and Poloxamer 407 (Polox)were employed as matrix materials, while hydroxypropyl-beta-cyclodextrin (HP-β-CD) was a solubilizer. The formulations were prepared via electrospinning and characterized for fiber morphology, drug dissolution, cytotoxicity, [...] Read more.
A novel ophthalmic delivery system utilizing levofloxacin-loaded, preservative-free, nanofiber-based inserts was investigated. Polyvinyl alcohol (PVA) and Poloxamer 407 (Polox)were employed as matrix materials, while hydroxypropyl-beta-cyclodextrin (HP-β-CD) was a solubilizer. The formulations were prepared via electrospinning and characterized for fiber morphology, drug dissolution, cytotoxicity, and antimicrobial activity. Scanning electron microscopy confirmed uniform fibrous structures. Fourier Transform Infrared spectroscopy and X-ray diffraction analyses demonstrated the amorphous state of levofloxacin within the fibers. In vitro dissolution studies revealed a rapid (within 2 min) and complete drug release, with higher HP-β-CD levels slightly delaying the release. Cytotoxicity tests showed increased HP-β-CD concentrations induced irritation, that was mitigated by sodium hyaluronate. The antimicrobial efficacy of the nanofibers was comparable to conventional eye drops, with lower minimum inhibitory concentrations for most tested strains. The nanofibrous formulation prepared from a PVA–Polox-based viscous solution of the drug:CD 1:1 mol ratio, containing 0.4% (w/w) sodium hyaluronate) was identified as a particularly promising alternative formulation due to its rapid and complete dissolution, good biocompatibility, and effective antimicrobial properties. Its gelling properties indicate that the residence time on the eye surface can be increased, potentially reducing discomfort and enhancing therapeutic outcomes. The nanofibrous formulations enhanced antimicrobial efficacy, providing a preservative-free alternative that minimizes the potential eye irritation that might occur because of the preservative agent and reduces the administrated dose frequency by extending the drug’s retention time on the eye’s surface. Subsequently, it improves patients’ adherence, which would reflect positively on the bioavailability. The levofloxacin-HP-β-CD nanofibers demonstrate promise as an alternative to traditional eye drops, offering advantages in solubility, stability, and patient compliance for ocular infection treatment.
