Carbon in Rechargeable Electrochemical Power
Rechargeable power sources are an essential element of large-scale energy systems based on renewable energy sources. One of the major challenges in rechargeable battery research is the development of electrode materials with good performance and low cost. Carbon-based materials have a wide range of properties, high electrical conductivity, and overall stability during cycling, making them suitable materials for batteries, including stationary and large-scale systems.

Carbon Intensity of Passenger Transport Modes
The transport sector is responsible for a significant amount of global carbon emissions, and several policies are being implemented at different levels to reduce its impact. To properly assess the effectiveness of planned measures, analysts often rely on average emission factors for different transport modes.

Carbon Nanofibers
Carbon nanofibers are nano-sized fibers that have a high degree of crystalline orientation. In recent years, ecological issues have led to the search for new green materials from biomass as precursors for producing carbon materials. Such green materials are more attractive than traditional petroleum-based materials, which are environmentally harmful and non-biodegradable.

Carbon Nanomaterials for Electro-Active Structures
The use of electrically conductive materials to impart electrical properties to substrates for cell attachment, proliferation and differentiation, represents an important strategy in the field of tissue engineering. Carbon nanomaterials have great potential for fabricating electro-active structures due to their exceptional electrical and surface properties, opening new routes for more efficient tissue engineering approaches. The concept of electro-active structures and their roles in tissue engineering is discussed in this review, the most relevant carbon-based nanomaterials used to produce electro-active structures are presented. Particular emphasis is put on the electrically conductive property, material synthesis and their applications on tissue engineering. Different technologies, allowing the fabrication of two-dimensional and three-dimensional structures in a controlled way, are also presented. Finally, challenges for future research are highlighted.

Carbon Nanotube Field-Effect Transistor
Carbon nanotubes (CNTs) are seamless nanotubes made of single or multiple layers of graphene sheets rolled around a central axis with the advantages of being lightweight and having a perfect hexagonal connection structure.

Carbon Nanotube Films as Sensor Material
The photo-thermoelectric (PTE) effect in electronic materials effectively combines photo-absorption-induced local heating and associated thermoelectric conversion for uncooled and broadband photo-detection. Formation of heterogeneous material junctions across the carbon nanotube (CNT)-film-based PTE sensors, namely photo-detection interfaces, triggers the Seebeck effect with photo-absorption-induced local heating. Typical photo-detection interfaces include a channel–electrode boundary and a junction between P-type CNTs and N-type CNTs (PN junctions). While the original CNT film channel exhibits positive Seebeck coefficient values, the material selections of the counterpart freely govern the intensity and polarity of the PTE response signals. Based on these operating mechanisms, CNT film PTE sensors demonstrate a variety of physical and chemical non-destructive inspections.

Carbon Nanotubes in Nanocomposite Mixed-Matrix Membranes
Carbon nanotubes (CNTs) are a popular material for gas separation because their walls are naturally smooth, allowing for faster gas transit than other inorganic fillers. It also has excellent mechanical strength, allowing membranes to work under high pressure. Although CNTs have superior qualities to other inorganic fillers, incorporating them into a polymer matrix is difficult due to CNTs' strong van der Waals forces, which cause agglomeration. CNT dispersion must be addressed if the full potential of CNTs is to be realized.

Carbon Nanotubes-Based Nano Materials
High modulus of about 1 TPa, high thermal conductivity of over 3000 W/mK, very low coefficient of thermal expansion (CTE), high electrical conductivity, self-lubricating characteristics and low density have made carbon nanotubes (CNTs) one of the best reinforcing materials of nano composites for advanced structural, industrial, high strength and wear-prone applications. This is so because it has the capacity of improving the mechanical, tribological, electrical, thermal and physical properties of nanocomposites.

Carbon Quantum Dots
Carbon dots have gained tremendous interest attributable to their unique features. Two approaches are involved in the fabrication of quantum dots (Top-down and Bottom-up). Most of the synthesis methods are usually multistep, required harsh conditions, and costly carbon sources that may have a toxic effect, therefore green synthesis is more preferable. Herein, the current review presents the green synthesis of carbon quantum dots (CQDs) and graphene quantum dots

Carbon Storage in Oil and Gas Industry
As a rapidly evolving technology, carbon capture and storage (CCS) can potentially lower the levels of greenhouse gas emissions from the oil and gas industry. A comprehensive review of different aspects of CCS technology is presented herein, including its key components, the methods and stages of carbon storage, implied environmental effects, and its pros and cons. It also investigates the utilization of CCS as an alternative method to water injection into oil reservoirs. It also probes the technical and operational challenges of implementing CCS technology in the oil and gas industry. Additionally, it examines the regulatory and policy issues associated with CCS, including incentives and frameworks for promoting the deployment of CCS technology. Finally, the potential benefits of CCS are discussed, including reducing the carbon footprint of the oil and gas industry, enhancing energy security, and supporting the transition to a low-carbon economy.
