Special Issue Information

Dear Colleagues,

In the last couple of decades, we have witnessed an improvement in multifunctional applications of nanomaterials. The nature of various applications has given birth to nanoscience and nanotechnology, integrating fundamental and applied scientific research from a range of fields, such as medicine, biology, chemistry, physics, engineering, environment, energy, enabling, agriculture, etc. Nanomaterial primary research and technological applications pave the way for emerging research in various disciplines involving and recognizing the nature of precise and improved outcomes at the nanoscale. Today, surface and electrochemical characterization methods involve the addressal of the dynamic nature of a nanomaterial’s surface chemistry and other properties impacting its interaction with different materials, as well as exploring its behavior in the surrounding environment. Advanced electrochemical and surface characterization tools can address challenging issues associated with nanomaterials, i.e., advance the understanding of change in interface reaction kinetics, hybrid structure stability, particle nature, surface defects, energy, and their potential. This Special Issue aims to compile significant developments in the fundamental understanding of assessing a material’s structure, interactions, and predicting environmental (physical, chemical, or biological) impacts. The Special Issue aims to cover topics ranging from quantum effects to fluorescence, electrocatalysis to energy harvesting, corrosion to gas evolution, self-healing, and electromagnetic shielding to electro-thermal conductivity.

Among energy storage devices, supercapacitors have received considerable attention in recent years owing to their high-power density and extended cycle life. Researchers are currently making efforts to improve energy density using different asymmetric cell configurations, which may provide a wider potential window. Many studies have been conducted on positive electrodes for asymmetric supercapacitor devices; however, studies on negative electrodes have been limited. In this study, iron oxides with different morphologies were synthesized at various deposition temperatures using a simple chemical bath deposition method. A nanosphere-like morphology was obtained for α-Fe2O3. The obtained specific capacitance (Cs) of α-Fe2O3 was 2021 F/g at a current density of 4 A/g. The negative electrode showed an excellent capacitance retention of 96% over 5000 CV cycles. The fabricated asymmetric solid-state supercapacitor device based on α-Fe2O3-NF//Co3O4-NF exhibited a Cs of 155 F/g and an energy density of 21 Wh/kg at 4 A/g. Full article
