Special Issue Information

Dear Colleagues,

We would like to invite all scientists, researchers and scholars in the field of multi-functional materials and applications, especially the participants of the 17th International Conference on Multi-functional Materials and Applications (ICMMA 2023, http://www.ijpcs.org/board/list.php), to submit their original research papers, short communications, and reviews to this Special Issue of Nanomaterials, entitled “Multi-Functional Materials and Applications: Basic Nanomaterials, Catalysis, Composite, Electronic and Biomaterials 2023”.

The conference topics and scope of this Special Issue will cover all aspects of basic nanomaterials, catalysis, composites, electronics and biomaterials, and this Special Issue will be divided into the following main sections:

  • Nanomaterials related to design, synthesis and modifications;
  • Nanomaterials related to characterization;
  • Nanomaterials related to applications.

These detailed categories in the field of nanomaterials will be devoted to recent advances in the synthesis, modification, and characterization of sensors, as well as the energy conversion and storage of nanomaterials. This includes materials that may be employed as biomaterials, the requirements they must meet, and problems that may be encountered in their application. Approaches from different fields of science (e.g., chemistry, engineering, human health and medicine) to the design, characterization, modification, and utilization of nanoscale biomaterials will be considered. Studies from these fields should focus on the latest advances in research related to all aspects of composites and environmentally friendly multi-functional nanomaterials, including methods for their synthesis and characterization and their possible applications.

We kindly encourage you to submit a manuscript regarding one of the above topics to this Special Issue.

Prof. Dr. Won-Chun Oh

Gas-sensing technology has witnessed significant advancements that have been driven by the emergence of graphene quantum dots (GQDs) and their tailored nanocomposites. This comprehensive review surveys the recent progress made in the construction methods and applications of functionalized GQDs and GQD-based nanocomposites for gas sensing. The gas-sensing mechanisms, based on the Fermi-level control and charge carrier depletion layer theory, are briefly explained through the formation of heterojunctions and the adsorption/desorption principle. Furthermore, this review explores the enhancements achieved through the incorporation of GQDs into nanocomposites with diverse matrices, including polymers, metal oxides, and 2D materials. We also provide an overview of the key progress in various hazardous gas sensing applications using functionalized GQDs and GQD-based nanocomposites, focusing on key detection parameters such as sensitivity, selectivity, stability, response and recovery time, repeatability, and limit of detection (LOD). According to the most recent data, the normally reported values for the LOD of various toxic gases using GQD-based sensors are in the range of 1–10 ppm. Remarkably, some GQD-based sensors exhibit extremely low detection limits, such as N-GQDs/SnO2 (0.01 ppb for formaldehyde) and GQD@SnO2 (0.10 ppb for NO2). This review provides an up-to-date perspective on the evolving landscape of functionalized GQDs and their nanocomposites as pivotal components in the development of advanced gas sensors. Full article
