ZnO has several potential applications into its credit. This review article focuses on the influence of processing parameters involved during the synthesis of ZnO nanoparticles by sol-gel method. During the sol-gel synthesis technique, the processing parameters/experimental conditions can affect the properties of the synthesized material. Processing parameters are the operating conditions that are to be kept under consideration during the synthesis process of nanoparticles so that various properties exhibited by the resulting nanoparticles can be tailored according to the desired applications. Effect of parameters like pH of the sol, additives used (like capping agent, surfactant), the effect of annealing temperature and calcination on the morphology and the optical properties of ZnO nanoparticles prepared via sol-gel technique is analyzed in this study. In this study, we tried to brief the experimental investigations done by various researchers to analyze the influence of processing parameters on ZnO nanoparticles. This study will provide a platform to understand and establish a correlation between the experimental conditions and properties of ZnO nanoparticles prepared through sol-gel route which will be helpful in meeting the desired needs in various application areas.

“…Sol-gel finds applications in a wide range of fields, such as thin films, optical coatings, corrosion-resistant coatings, composites, and powders [27]. Parameters like the H 2 O/TEOS ratio, the choice of organic solvents, pH, the type of catalyst (base or acid catalyst), temperature, and other factors play a crucial role in determining the properties and structure of organic polymer/inorganic metal oxide hybrids when characterised through the sol-gel method [28].…”

Cellulose/silica nanocomposites, synthesised through the sol–gel technique, have garnered significant attention for their unique properties and diverse applications. The distinctive characteristics of these nanocomposites are influenced by a range of factors, including the cellulose-to-silica ratio, precursor concentration, pH, catalysts, solvent selection, temperature, processing techniques, and agitation. These variables play a pivotal role in determining the nanocomposites’ structure, morphology, and mechanical properties, facilitating tailoring for specific applications. Studies by Raabe et al. and Barud et al. demonstrated well-deposited silica nanoparticles within the interstitial spaces of cellulosic fibres, achieved through TEOS precursor hydrolysis and the subsequent condensation of hydroxyl groups on the cellulose fibre surface. The introduction of TEOS established a robust affinity between the inorganic filler and the polymer matrix, emphasising the substantial impact of TEOS concentration on the size and morphology of silica nanoparticles in the final composites. The successful functionalisation of cellulose fibres with the TEOS precursor via the sol–gel method was reported, resulting in reduced water uptake and enhanced mechanical strength due to the strong chemical interaction between silica and cellulose. In research conducted by Feng et al., the silica/cellulose composite exhibited reduced weight loss compared to the pristine cellulose matrix, with the integration of silica leading to an elevated temperature of composite degradation. Additionally, Ahmad et al. investigated the effects of silica addition to cellulose acetate (CA) and polyethylene glycol membranes, noting an increase in Young’s modulus, tensile strength, and elongation at break with silica incorporation. However, concentrations exceeding 4% (w/v) resulted in significant phase separations, leading to a decline in mechanical properties.

In the field of investigating nano-fabrication, it is not possible to reach a single and separate definition compared to macro-fabrication. Nano-fabrication can be defined as an assembly process to produce a one-dimensional, two-dimensional, or three-dimensional structure at the nanometer scale. The importance of recognizing and examining nanofabrication techniques considering the revolution that nanofabrication compounds have in molecular adsorption, catalysis, magnetism, luminescence, nonlinear optics, and molecular sensing, have been known because they provide the possibility of reproducible mass production in this field. In this chapter, to create a general understanding of nano-fabrication and the challenge of creating nanometer size reduction, we will review new tools and techniques for the production of nanostructures, which are divided into three major parts: thin film, lithography, and engraving.
