Recent Advances in Thin Films and Coatings of Surface Engineered Nanomaterials for Energy and Environmental Applications

Dear Colleagues,

The burgeoning growth of the global economy and the technological industrial revolution now demand advanced solutions regarding energy and environmental sustainability that enhance our standards of living and promote an eco-friendly society. The fields of nanotechnology and materials science have converged to create advanced hybrid nanomaterial-based coatings and thin films with unprecedented properties and functionalities for novel device applications. The latest advancements in uniform thin film coatings and surface deposition techniques have garnered attention concerning the development, design and fabrication of novel nanomaterial-based devices, particularly in the fields of electronics, energy, environmental protection, biomedicine, and space. Surface science, engineering and novel coating technologies for nanomaterials and their hybrid heterostructures have led to the possibility of achieving exceptional optoelectrical, physical, mechanical, chemical and biomedical properties. In addition, the effective integration of artificial intelligence and machine learning (AI/ML) and density functional theory (DFT) prediction into nanotechnology has significantly enhanced the design and optimization of nanomaterial coatings and thin films, enabling precise predictions of material properties and behaviours. Such advanced computational approaches drive innovation, efficiency, and sustainability, accelerating the development of high-performance devices in these critical fields. These innovations are also propelling advancements regarding the provision of deep and new scientific conceptual knowledge, delivering in-depth systematic investigations and technical solutions that address major global challenges, especially in both the energy and environmental sectors. Such innovative investigations are highly encouraged due to the extensive applicative potential of devices developed using nanomaterials. These include smart food packaging, energy production and storage devices, flexible, wireless and cost-effective sensors for detecting flammable and hazardous gases, advanced diagnostic techniques for IoT-based biomedical devices, water pollutant removers, long-lasting prosthetics, smart drug delivery systems more efficient thermal insulation materials for buildings, and many others.

This Special Issue aims to capture the latest advancements and provide a comprehensive overview of how the latest progress in nanomaterial coatings and their surface engineering is revolutionizing electronics, devices for environmental protection, energy production and storage applications for sustainability.
