“…Carbon nanodots (CDs) refer to a class of zero-dimension carbon nanoparticles such as carbon quantum dots (CQDs), graphene quantum dots (GQDs), carbonized polymer dots (CPDs), carbonized polymer dots (CPDs) and various carbogenic nanodots (CNDs) [81,82]. Their carbon cores is usually sp 2 hybridized with different functional groups such as amino group, epoxy, ether, carbonyl, aldehyde, hydroxyl, and carboxylic acid functional groups on the surface [81,83]. They are quasi-spherical, amorphous to crystalline in nature with size less than 10 nm as shown in Figure 5 [81].…”

“…Although CDs have various advantages, they also suffer from problems associated with aggregation of pristine CDs in solid state. This often leads to property change such as luminescence quenching, surface defects, and decreasing surface areas [81]. To mitigate these unwanted phenomena, and to further optimize their optical and electrical properties, various solid supports such as polymer matrices, inorganic salts and porous materials (PMs), etc., have been used to support CDs [94,95].…”

There is great importance and need of improving existing carbon materials fabrication methods. As such, this work proposes to discuss, interrogate, and propose viable hydrothermal, solvothermal, and other advanced carbon materials synthetic methods. The advanced carbon materials to be interrogated will include the synthesis of carbon dots, carbon nanotubes, nitrogen/titania-doped carbons, graphene quantum dots, and their nanocomposites with solid/polymeric/metal oxide supports. This will be done with special mind to microwave-assisted solvothermal and hydrothermal synthesis due to their favourable properties such as rapidity, low cost, and green/environmentally-friendliness. Thus, these methods are important during the current and future synthesis and modification of advanced carbon materials for application in energy, gas separation, sensing, and water treatment. Simultaneously, the work will pay special cognizance to methods reducing the fabrication costs and environmental impact while enhancing the properties as a direct result of the synthesis methods. As a direct result, the expectation is to impart a significant contribution to the scientific body of work regarding the improvement of the said fabrication methods.

Real‐time monitoring of wound healing remains a major challenge in clinical tissue regeneration, calling the need for the development of biomaterial‐guided on‐site monitoring wound healing technology. In this study, multifunctional double colorimetry‐integrated polyacrylamide‐quaternary ammonium chitosan‐carbon quantum dots (CQDs)‐phenol red hydrogels are presented, aiming to simultaneously detect the wound pH level, reduce bacterial infection, and promote wound healing. The hybridization of CQDs and pH indicator (phenol red) with the hydrogels enables their high responsiveness, reversibility, and accurate indication of pH variability to reflect the dynamic wound status in the context of both ultraviolet and visible light. Furthermore, these visual images can be collected by smartphones and converted into on‐site wound pH signals, allowing for a real‐time evaluation of the wound dynamic conditions in a remote approach. Notably, the hydrogels exhibit excellent hemostatic and adhesive properties, maintain sufficient wound moisture, and promote wound healing via their high antibacterial activity (against Staphylococcus Aureus, and Escherichia Coli) and skin repair function. Overall, the resulting hydrogels have high potential as a novel smart and flexible wound dressing platform for theranostic skin regeneration.

Asymmetric supercapacitors (ASCs) can substantially broaden their working voltage range, benefiting from the advantages of both cathode and anode while breaking through the energy storage limitations of corresponding symmetric cells. Wide voltage aqueous ASCs hold great promise for future electronic systems that require satisfied energy density, power density, and cycle life, due to the advantages of aqueous electrolyte in terms of low cost, operational safety, facile manufacture, environment-friendly, and high ionic conductivity. This review will first briefly present an overview of the historical developments, charge storage mechanisms, and matching principles of wide voltage aqueous ASCs. Then, the cathode and anode materials with wide potential windows for building wide voltage aqueous ASCs over the last few decades are summarized. The next section details the optimization methods of aqueous electrolyte related to wide voltage aqueous ASCs. In addition, the basic device configurations of wide voltage aqueous ASCs are classified and discussed. Furthermore, several strategies are proposed for achieving highperformance wide voltage aqueous ASCs in terms of voltage window, specific capacitance, rate performance, and electrochemical stability. Finally, to motivate further research and development, several key scientific challenges and the perspectives are discussed.
