Special Issue Information
Dear Colleagues,
During the last few decades, rigorous empirical research has been carried out on numerous nanotechnology applications, such as on environmental applications, renewable energy systems, semiconductors, skincare products, health impacts, pharmaceuticals, and so forth. Nanostructures comprising nanofilms or nanoparticles are relatively new material classes with a size under 100 nm that can be 0D, 1D, 2D, or 3D. Slightly modifying these nanostructures can allow for tuning their physicochemical characteristics (curing temperature, dielectric characteristics, thermal conductivity, adsorption, photocatalytic capabilities, corrosion resistance, etc.), making them ideal for a variety of applications. However, creating new, highly specialized nanomaterials can be challenging and requires lengthy research and development.
Nanomaterials can improve a system’s performance during its entire life span and help it to retain sustainable efficiency. They mitigate environmental effects, enhance competitiveness and material recycling, and increase materials’ reusability. Nanomaterials should have a reduced impact on the environment, often achieved through green technologies. Nanomaterials improve their performance over their entire lifespan and preserve proper functionality, as described previously, but particular emphasis should be placed on avoiding nanomaterial contamination. The primary goal of this Special Issue is to raise awareness regarding nanomaterials’ development and utilization due to the free availability of solar radiation and their great benefits in applications such as environmental remediation, chemical synthesis, renewable energy production, and energy storage. Nanomaterials are applied widely in all sectors of modern society; however, phytoremediation has attracted remarkable levels of interest because it generates low-cost and high-efficiency renewable electricity.
A wide range of photocatalytic materials with controlled dimensions and features have been developed thus far. On substrates covered with a thin layer of photocatalyst, microorganism inactivation and organic matter mineralization have also been seen following advanced oxidation processes. Water recycling has expanded considerably over the years due to increased water demand. This is attributable to both population growth and urbanization. From this standpoint, improved water management and treatment research has grown tremendously. In recent years, technological advances have arisen to handle new constraints such as microorganisms, non-biodegradable wastes, and chronic contaminants. The creation of innovative materials with a set of unique and distinctive properties such as strong catalytic activity, outstanding selectivity, long-term durability, and environmental sustainability is important. Thanks to efforts to design novel nanomaterials with potential applications, approaches to their synthesis are also in continual development. Furthermore, technological advancements must be supported by a continuing requirement to verify that these characteristics are environmentally friendly. The scientific literature states that the diversity of nanostructures is considerable.
We invite you to submit research articles, communications, reviews, and brief papers highlighting recent advances and breakthroughs in advanced functional nanomaterials. We would like to collect all contributions that illustrate the developments and applications of nanomaterials from a technical and analytical perspective. This Special Issue aims to collect innovative achievements in the research field of mechanical, thermal, energy, electrical, catalysis, optical, and magnetic properties based on multi-functional nanomaterials.
The list of potential topics to be covered includes:
- Inorganic and organic nanoparticles for electrocatalysis and photocatalysis
- Nanoparticles’ synthesis, characterization, and applications
- Energy storage nanomaterials and future challenges
- Bottom-up approach for the development of functional nanomaterials
- From the fundamentals of nanomaterials engineering and innovation to their applications

Abstract: In-depth structural analysis of spinel BaFeCr2O4 nano-particles synthesized by sol-gel process using X-ray powder diffraction (XRD), Scanning electron microscopy (SEM), Energy dispersive X-ray spectroscopy (EDS), Raman and photoluminescence spectroscopy due to its low sintering temperature using barium nitrate, chromium nitrate and 1,2-ethanediol has been reported. Citric acid was used as a complexing agent. Doped nanoparticles sintered at 750 ˚C for four hours are crystalline as demonstrated by X-ray diffraction (XRD). SEM micrographs shows less spherical structure. Photoluminescence spectra reveals pure BaCr2O4 bandgap about 3.26 eV that lowers to value 3.1 eV for barium doped iron chromite. Raman spectra Based on these findings, it seems likely that Ba1-xFxCr2O4 nanoparticles in the future will find usage in many applications including energy storage and photocatalytic activity.
