Carbon-Based Nanomaterials for Bone Regeneration
This work explores the potential research opportunities and challenges of 3D printed biodegradable composite-based scaffolds containing carbon-based nanomaterials for bone tissue engineering applications. Bone possesses an inherent capacity to fix itself. However, when a defect larger than a critical size appears, external solutions must be applied. Traditionally, autograft has been the most used solution in these situations. However, it presents some issues such as donor-site morbidity. In this context, porous biodegradable scaffolds have emerged as an interesting solution. For adequate performance, these scaffolds must meet specific requirements: biocompatibility, interconnected porosity, mechanical properties, and biodegradability. The development of additive manufacturing methods has proposed a promising solution for this application since they allow the complete customization and control of scaffolds geometry and porosity. Furthermore, carbon-based nanomaterials present the potential to impart osteoconductivity and antimicrobial properties and reinforce the matrix from a mechanical perspective. These properties make them ideal for use as nanomaterials to improve the properties and performance of scaffolds for bone tissue engineering.

Carbon-Based Nanomolecules Interacting with Proteins
Scientists are designing new ways to combine proteins and carbon-based nanomomecules. We review strategies of selecting proteins able to interact with proteins and typical van der Waals interactions. Proteins and carbon based nanomomecules can form ordered clusters of hybrid materials and will guide new projects for bioimaging tools and tuning of intrinsically disordered proteins.

Carbon-Based Quantum Dots for Supercapacitors
Carbon-based Quantum dots (C-QDs) are carbon-based materials that experience the quantum confinement effect, which results in superior optoelectronic properties. In recent years, C-QDs have attracted attention significantly and have shown great application potential as a high-performance supercapacitor device. C-QDs (either as a bare electrode or composite) give a new way to boost supercapacitor performances in higher specific capacitance, high energy density, and good durability. This review comprehensively summarizes the up-to-date progress in C-QD applications either in a bare condition or as a composite with other materials for supercapacitors. The current state of the three distinct C-QD families used for supercapacitors including carbon quantum dots, carbon dots, and graphene quantum dots is highlighted.

Carbon-Based Textile Sensors for Different Physiological-Signal Monitoring
As the focus on physical health increases, the market demand for flexible wearable sensors increases. Textiles combined with sensitive materials and electronic circuits can form flexible, breathable high-performance sensors for physiological-signal monitoring. Carbon-based materials such as graphene, carbon nanotubes (CNTs), and carbon black (CB) have been widely utilized in the development of flexible wearable sensors due to their high electrical conductivity, low toxicity, low mass density, and easy functionalization.

Carbon-Fiber-Reinforced Polymers in Circular Economy
Thermosetting Carbon-Fiber-Reinforced Polymers (CFRPs) are engineered composites made out of carbon fibers (CFs) as the reinforcement and epoxy resin as the polymer matrix, which acts as load transfer elements across fibers.Thermosets are commonly charachterized by their high performance and flexibility according to different combination of polymeric-based materials (e.g. epoxies, polyurethane, rubber) and carbon fibers type. CFRPs owns durable and heat-resistant features that make proper them for cars or electrical appliances. CFRPs cannot be easily recycled or broken down after use, because the chemical bonds holding them cannot be changed or reversed as for thermoplastic material. New technological solutions are emerging with specific focus on the circular economy context.

Carbon-LiFePO4 Cathodes for Lithium-Ion Batteries
Li-ion batteries are in demand due to technological advancements in the electronics industry; thus, expanding the battery supply chain and improving its electrochemical performance is crucial. Carbon materials are used to increase the cyclic stability and specific capacity of cathode materials, which are essential to batteries. LiFePO4 (LFP) cathodes are generally safe and have a long cycle life. However, the common LFP cathode has a low inherent conductivity, and adding a carbon nanomaterial significantly influences how well it performs electrochemically.

Carbon–Manganese Dioxide Composite in Supercapacitors
One of the global problems is environmental pollution by different biowaste. To solve the problem, biowaste must be recycled. Waste-free technology is also a way of saving exhaustible raw materials. Research on electrochemical energy sources is currently the most dynamically developing area of off-grid energy. Electrochemical capacitors can operate for a long time without changing performance, they have smaller dimensions, high mechanical strength, and a wide operating temperature range. These properties are effective energy-saving devices. Therefore, supercapacitors are widely used in various industries.

Carbonation and Its Mechanisms in Reinforced Concrete Structures
Reinforced concrete (RC) has been commonly used as a construction material for decades due to its high compressive strength and moderate tensile strength. However, these two properties of RC are frequently hampered by degradation. The main degradation processes in RC structures are carbonation and the corrosion of rebars. The scientific community is divided regarding the process by which carbonation causes structural damage. Some researchers suggest that carbonation weakens a structure and makes it prone to rebar corrosion, while others suggest that carbonation does not damage structures enough to cause rebar corrosion.
