Fabrication of silica (SiO2) nanocrystals using sol–gel method with enhanced antimicrobial and photocatalytic activity
Sodium silicate (Na2SiO3) and acetic acid (CH3COOH) were used as catalysts in a one-phase, practical, economical, and rapid sol–gel process to produce silica (SiO2) nanocrystals. The influence of the irradiation temperature using a microwave oven and the characteristics of the synthesized SiO2 nanocrystals were examined to know its parameters and boundaries. The motivating factor for the investigation is to obtain a SiO2 in crystalline nature which is nanoscale dimension. X-ray Diffraction (XRD), Fourier Transmission InfraRed (FTIR), UV–Visible spectroscopy, Scanning Electron Microscopy- Energy Dispersive Spectrometer (SEM–EDX), and ThermoGravimetric Analysis—Differential Scanning Calorimetry (TG-DSC) were used in the characterization technique, and its potential for performing as antibiotic enhancers are also examined and explored. Furthermore, the photocatalytic activities of the synthesized nanocrystal was investigated as photocatalyst against methylene blue (MB) dye under UV irradiation.
期刊介绍：
The objective of the Journal of Nanoparticle Research is to disseminate knowledge of the physical, chemical and biological phenomena and processes in structures that have at least one lengthscale ranging from molecular to approximately 100 nm (or submicron in some situations), and exhibit improved and novel properties that are a direct result of their small size.
Nanoparticle research is a key component of nanoscience, nanoengineering and nanotechnology.
The focus of the Journal is on the specific concepts, properties, phenomena, and processes related to particles, tubes, layers, macromolecules, clusters and other finite structures of the nanoscale size range. Synthesis, assembly, transport, reactivity, and stability of such structures are considered. Development of in-situ and ex-situ instrumentation for characterization of nanoparticles and their interfaces should be based on new principles for probing properties and phenomena not well understood at the nanometer scale. Modeling and simulation may include atom-based quantum mechanics; molecular dynamics; single-particle, multi-body and continuum based models; fractals; other methods suitable for modeling particle synthesis, assembling and interaction processes. Realization and application of systems, structures and devices with novel functions obtained via precursor nanoparticles is emphasized. Approaches may include gas-, liquid-, solid-, and vacuum-based processes, size reduction, chemical- and bio-self assembly. Contributions include utilization of nanoparticle systems for enhancing a phenomenon or process and particle assembling into hierarchical structures, as well as formulation and the administration of drugs. Synergistic approaches originating from different disciplines and technologies, and interaction between the research providers and users in this field, are encouraged.
