From Solid-State to Liquid-State: Smart, Sustainable, and Recyclable Magnetic/Electronic Nanomaterials for Energy, Environmental, and Biomedical Applications

Dear Colleagues,

Magnetic and electronic nanomaterials have emerged as a cornerstone of modern materials science, offering unique and tunable properties that enable a wide range of advanced technologies. The rapid evolution of this field now extends beyond traditional solid-state systems to include emerging liquid-state materials, such as magnetic liquid metals, ferrofluids, magnetic fluids, and other hybrid soft-matter nanostructures. This transition opens new opportunities for designing smart, sustainable, and recyclable materials capable of addressing the growing demand for environmental responsibility and multifunctional performance.

Recent breakthroughs in synthesis, surface engineering, and device integration have enabled these nanomaterials to perform effectively across diverse applications—from environmental sensing, remediation, and energy storage/harvesting/generator to biomedical imaging, therapy, and bioelectronics. The combination of magnetic responsiveness, electrical conductivity, and structural adaptability makes them ideal candidates for flexible, stretchable, and reconfigurable devices. Furthermore, an increasing emphasis on green fabrication processes, recyclability, and life-cycle management aligns these developments with global sustainability goals.

This Special Issue aims to highlight the latest research and innovations in magnetic and electronic nanomaterials across solid- and liquid-state platforms, with a particular focus on sustainable design, smart functionalities, and real-world applications. We welcome original research articles, short communications, and comprehensive reviews in areas including, but not limited to, the following:

• Design, synthesis, and characterization of magnetic and electronic nanomaterials;
• Solid-state and liquid-state nanostructures with tailored physical and chemical properties;
• Nanomagnetic materials for energy storage, harvesting, and nanogenerators;
• Smart, flexible, and stretchable devices based on magnetic/electronic nanomaterials;
• Recyclable and eco-friendly nanomaterials and fabrication methods;
• Magnetic nanomaterials for environmental monitoring, remediation, and resource recovery;
• Electronic and multifunctional nanomaterials for biomedical diagnostics and therapy;
• Device integration strategies, performance optimization, and durability enhancement;
• Advanced modeling and simulation of nanomaterial behavior in solid- and liquid-state systems.

By bridging fundamental science with application-driven innovation, this Special Issue will serve as a platform for interdisciplinary dialogue and the dissemination of pioneering research that will shape the future of sustainable magnetic and electronic nanotechnology.
