Summary: This study investigates the efficient removal of dimethoate from water using activated carbon fibers (ACFs) derived from viscose fibers. The chemical composition and textural properties of ACFs were effectively tuned by changing the amount of a specific chemical, resulting in reduced toxicity of treated water samples. Multiple linear regression models were established to predict the performance of ACFs in removing dimethoate from water.

Summary: The fabrication and electrochemical performance of thick activated carbon electrodes with carbonized lignin-derived carbon fiber inclusions are reported. The addition of carbonized lignin-derived carbon fibers improves the flexibility and conductivity of the electrode, leading to increased specific capacitance. The use of a environmentally friendly binder, microfibrillated cellulose, serves as a robust and safe alternative to commonly used hazardous binders.

Summary: This study investigates the influence of supercritical CO2 (ScCO2) injection on the water wettability of shale. The results show that the water contact angles of shale generally increase and the wettability weakens after ScCO2 exposure. This change may have positive effects on gas seepage but negative effects on CGS stability.

Summary: A method for preparing high surface area nanoporous activated carbon fibers from spider silk (a natural biomaterial) using potassium hydroxide activation is reported. The fibers have a high specific surface area and oxygen-rich surface, providing enhanced CO2 capture and storage capacity for energy carrier gases (H-2 and CH4). The fibers also demonstrate easy regeneration and minimal loss in uptake capacity. This study shows that biomaterials can be effectively converted into high surface area activated carbon fibers for advanced energy and environmental applications.

Summary: Carbon-based compounds, including activated carbon (AC), graphene, and their composites, are gaining research interest due to their unique physicochemical attributes. These materials show excellent performance in various applications such as water treatment, energy storage, and electrochemical sensing. This review examines the synthesis, applications, kinetics, isotherm models, and adsorption behavior of AC-graphene derivatives/composites (AC/GC) in water treatment scenarios. Future research should focus on optimizing eco-friendly preparation techniques, investigating regeneration and recycling methods, and exploring the safety of graphene-based materials in aquatic environments. Moreover, there is a need to clarify the kinetics, isotherm models, and mechanisms in air purification, energy storage, and sensor applications. The transition from laboratory to industrial-scale production and application of these materials is also discussed.

Summary: The transition to a carbon-neutral energy sector requires the development of new storage materials for hydrogen and methane as well as new solutions for carbon capture and storage. Activated carbons, with their high specific surface area and other favorable properties, are considered promising adsorbents for these purposes. This study focuses on the synthesis and characterization of activated carbons starting from amorphous cellulose, with and without the inclusion of copper nanoparticles, and investigates the effects of different nanoparticle concentrations on porosity and gas storage properties.
