This study investigates the removal of CAP from aqueous solutions using biochar derived from pinecones. The biochars were activated at 800°C using KOH with different mass ratios to the carbonized sample (2:1, 4:1, and 6:1). Among them, the biochar with a KOH ratio of 4:1 (PCK4-800) exhibits the highest pore volume (1.8 cm³ g⁻¹) and a specific surface area (3131.6 m² g⁻¹). Batch experiments reveal that the CAP adsorption capacity of the biochar is positively correlated with its specific surface area. At pH 7, PCK4-800 achieves a removal efficiency of up to 92% for a 100 mg L⁻¹ CAP solution using a dosage of just 0.1 g L⁻¹. This performance surpasses that of recently reported adsorbents. Kinetic and thermodynamic model fitting results indicate that chemical adsorption within a monomolecular layer dominates physical adsorption. The primary adsorption mechanisms involve pore filling and π-π interactions, while secondary mechanisms include electrostatic effects and hydrogen bonding. Thermodynamic parameters confirm that the adsorption process is endothermic and spontaneous. Moreover, the removal efficiency of PCK4-800 remains above 80% after five regeneration cycles. In summary, the high removal efficiency and excellent regeneration potential of PCK4-800 demonstrate its suitability as an effective adsorbent for antibiotic removal.</p>","PeriodicalId":100258,"journal":{"name":"CleanMat","volume":"2 1","pages":"72-84"},"PeriodicalIF":0.0,"publicationDate":"2025-02-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/clem.21","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143877783","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

With over 82% of biomass (BM) coming from plants, primarily trees, plants are the dominant form of life on Earth. BM represents a readily available, ecologically favorable, and renewable low-cost carbon source. Its rational disposal has emerged as a critical challenge in modern times due to its widespread generation from farming, manufacturing, and forestry activities. Nanotechnology (NT) has enormous potential for a wide range of BM-related applications, including BM development, processing technique, modification, and utilization. Richard Feynman, a physicist who later won the Nobel Prize in Physics, presented a discussion in 1959 titled “There's Plenty of Room at the Bottom.” This address was the beginning of the New Theory of Physics, which is NT, where he discusses the potential of NT for manipulating matter at the atomic level. In recent years, there has been a significant surge in interest surrounding carbon nanomaterials (CNMs), specifically carbon nanotubes (CNTs) and graphene. These materials have captured the interest of researchers due to their extraordinary characteristics and widespread applications. Utilizing BM as a source shows great potential in creating functional carbon materials (CMs) due to its sustainability, affordability, and high carbon content. Nowadays, CNMs derived from BM have been a popular area of study. Various structures, synthesis techniques, and widespread applications of CNMs have been documented. Thus, this review provides a detailed overview that outlines the latest technological advancements in the fabrication of BM-derived CMs. It also studies the production of high-value-added CNMs from BM and delves into the utilization of BM-based CNMs as a precursor for textile wastewater treatment. Furthermore, this study also outlines the progress of BM-derived CNMs in supercapacitors (SCs), sensors, battery electrode materials, fuel cells (FCs), and E-textiles, showcasing their pivotal role in advancing sustainable technologies for the future.</p>","PeriodicalId":100258,"journal":{"name":"CleanMat","volume":"2 1","pages":"4-58"},"PeriodicalIF":0.0,"publicationDate":"2024-12-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/clem.15","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143877781","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, this increased activity has also resulted in an elevated risk of oil-related disasters, which can have devastating consequences for the environment and local communities. More than 1700 oil spills have occurred, including severe spills such as the Deepwater Horizon spill in 2010, which released 134 million gallons. However, technological developments and restrictions have resulted in a significant reduction in spills. Oil spills happened in aquatic and terrestrial environments providing numerous impacts on wildlife and public health. Existing literature may have limited scope or depth; therefore, this review addresses the literature gap by discussing the strengths and limitations of current and emerging technologies for detecting, cleaning, and restoring oil-contaminated marine and soil sites. Booms, skimmers, chemical agents (dispersants), and in situ burning are generally used for oil spill remediation. Other than conventional methods, numerous novel approaches including adsorbents (e.g., aerogels, carbon nanotubes, and other sorbents) and modified materials have been developed. For detection purposes, collaboration remote sensing and artificial intelligence are used as new emerging technologies. Modified oil adsorbents such as aerogels, sponges, and carbon nanotubes demonstrated high sorption capacity (&gt; 100 g/g) for oil removal. Despite the challenges such as transport, high production cost, and toxicity, these emerging technologies have the potential to improve the effectiveness of oil spill remediation in the future.

Exposure to PFAS is linked to adverse reproductive outcomes and elevated blood pressure in pregnant individuals, and it negatively impacts aquatic ecosystems, particularly algal populations and microbial communities. This evaluation focuses on biochar's efficacy and cost-efficiency in removing PFAS from water, highlighting its potential as a sustainable remediation method. Biochar's high microporous volumes (0.1–1.0 cm³/g), aromaticity, and surface oxygen-containing functional groups make it effective for PFAS adsorption. Various biochar production methods, such as pyrolysis of biomass waste, and innovative modification techniques like acid treatment, ball milling, and metal nanoparticle incorporation are explored to enhance PFAS adsorption capacity. The mechanisms, kinetics, and thermodynamics of PFAS adsorption onto biochar are examined, providing insights into molecular-level interactions and adsorption isotherms. Furthermore, machine learning models are utilized to understand the impact of processing parameters on PFAS removal efficiency. The review also presents toxicological studies on the harmful effects of PFAS exposure on organisms and humans, emphasizing the urgent need for effective remediation strategies.

Due to its widespread use, its presence in the environment has been on the rise. This study discusses the degradation of the antibiotic SMX through the ozonation process. SMX is preferentially degraded by the direct action of O₃ on the molecule, starting by breaking the double bonds in the aromatic ring. Through ozonation it is possible to obtain complete SMX degradation within 10 min, but the mineralization of the solution is not achieved, reaching total organic carbon removal efficiencies of 5%–60%, depending on the reaction time. Factors such as the presence of organic matter (OM) and the pH of the solution interfere with the degradation of SMX. The OM acts as a radical scavenger, decreasing the efficiency of degradation, while the pH interferes with the decomposition of O₃ into radicals and the dissolution of the oxidant in the medium, in addition to influencing the state of ionization of the SMX making it more or less prone to reactions. In general, most other remediation processes are carried out on a laboratory scale. To increase the level of these processes to a full scale, more pilot-scale studies are needed. In addition, it is necessary to focus on the practice of reusing materials, avoiding the generation of secondary pollution, and increasing the useful life of the material. The review also discusses the reaction mechanisms, intermediate compounds formed, mineralization of the solution, and factors that influence the process, which can help in making decisions for future studies to be carried out in the area.

Here, we present a novel solvent free approach to fabricate multifunctional carbon nanotubes (CNTs) reinforced biobased and recyclable epoxy thermoset composites through precuring in an internal mixer followed by curing in an oven. The epoxy matrix, a covalent adaptable network (CAN) based on dynamic imine bonds, was synthesized from entirely biobased feedstocks, including glycerol triglycidyl ether, vanillin, and 1,10-diaminodecane. The shear force during precuring facilitated dispersion of CNTs in CAN matrix, allowing for high CNTs loading (up to 20 wt%). The well-dispersed CNTs not only reinforced mechanical properties of CAN but also introduced new functionalities like electrical conductivity, electromagnetic interference (EMI) shielding capacity, and Joule heating performance. The composite with 20% CNTs exhibited a tensile strength and Young's modulus of 78.1 MPa and 3.07 GPa, respectively, marking a 34.2% and 63.6% improvement over pristine CAN. It also demonstrated a high electrical conductivity of 35.3 S/m, resulting in a remarkable EMI shielding effectiveness (22.8 dB) and excellent Joule heating performance (reaching 131.7°C at 27 V input).
