“…There are few studies in the literature on the occurrence of carbonation and its effects on the durability of soils treated with lime-based materials [25]. More recently, studies have been developed that address this aspect in more detail [22,25,32,[36][37][38][39][40][41][42][43][44][45][46][47], but there is still no study in the literature that presents the in uence of carbonation processes in tropical soils stabilized with EAFS, especially considering the mechanical tests that apply to structural materials of asphalt pavements (e.g., resilient modulus and CBR index).…”

Although the treatment of soils with lime-based materials is used in many earthworks projects, there are only a few studies that deal with the quantification of their carbonation.The objective of this work was to investigate the influence of carbonation in mixtures between two samples of tropical soils and Electric Arc Furnace Slag (EAFS) in terms of Unconfined Compressive Strength (UCS), mini-CBR index, mini-CBR expansion, and Resilient Modulus (RM) properties. Four types of curing were used: (1) conventional sealed curing in a humid chamber; (2) conventional sealed curing in a humid chamber followed by unsealed curing with exposure to air; (3) conventional sealed curing in a humid chamber followed by unsealed curing in an accelerated carbonation chamber. In addition, tests were performed to determine the carbonation depth by spraying phenolphthalein, pH, scanning electron microscopy (SEM), and X-ray diffraction (XRD). It was found that the results of the soil-EAFS were better than those of the soil samples not stabilized for all the curing processes analyzed. In the curing processes (1), the formation of calcium aluminum silicate hydrate structures (CASH) was found to improve the mechanical behavior of soil-EAFS mixtures. The formation of calcium carbonate (CaCO3) was observed in curing processes (2) and (3), which significantly improved the mechanical properties. Thus, the carbonation process increases the strength and stiffness of the soil-EAFS mixtures, which guarantees the durability of these mixtures over the years.

“…There is no doubt about the environmental problems produced as a consequence of the extended use of carbonaceous fuels, where carbon dioxide (CO 2 ) and carbon monoxide (CO) are produced . Based on that, carbon capture, utilization, and storage (CCUS) have become important developing technologies, where significant advances have been achieved. − …”

Scrutinizing the CO Chemical Capture Path in Li₂MnO₃ Samples with Different Microstructural Properties

Hydrothermal and ball-milling procedures combined with the solid-state reaction method were proposed as alternative synthesis routes to modify microstructural Li2MnO3 powders. All these materials were compared against Li2MnO3 prepared by following the solid-state reaction method only. To totally understand the effect of the synthesis routes proposed, the modified samples were structurally and microstructurally analyzed and subsequently subjected to the CO chemisorption process. Li2MnO3-modified samples exhibited important differences and improvements during the CO chemisorption process, in comparison to the powders obtained through the solid-state reaction method, associated with important variations on their microstructural features. Specifically, the sample prepared by the hydrothermal bottom-up approach and labeled as HSS700 showed the best CO chemisorption. This result was explained based on its crystal and particle sizes, morphology, and specific surface area. Moreover, the whole analysis performed on all the samples allowed one to determine that the solid–gas interphase controls the CO chemisorption over the CO-Li2MnO3 kinetics.

“…On the other hand, ion-exchange resins have the ability to selectively eliminate ions and contaminants. Synthetic polymers provide a wide range of applications in effectively tackling several categories of water contaminants, hence augmenting the efficacy of treatment procedures and optimising overall process efficiency [14]- [15]. The use of advanced nanomaterials, which are deliberately designed and fabricated at the nanoscale, has significantly expanded the possibilities in the field of water treatment [16].…”

The increasing apprehension regarding water shortage and environmental contamination has heightened the pursuit of sustainable remedies in the field of water treatment. This detailed research examines the use of sustainable materials in water treatment systems. This study aims to examine the pressing demand for environmentally friendly and highly effective methods of water treatment. It comprehensively explores a diverse range of sustainable materials, encompassing both natural biomaterials and sophisticated nanomaterials. The evaluation of key features such as adsorption capacity, selectivity, and regeneration potential is conducted for each material, hence offering valuable insights into their suitability for the purpose of pollutant removal and water purification. The present study provides a critical evaluation of the appropriateness of these sustainable materials by an examination of key criteria like adsorption capacity, selectivity, and regeneration capabilities. The aforementioned attributes, which are crucial for the elimination of pollutants and unwanted substances, highlight the significant contribution of these materials towards the progression of water purification methodologies. In addition to their practical attributes, the analysis explores the ecological consequences and enduring viability of these substances, emphasising the need of mitigating detrimental impacts on natural systems and their associated services. The evaluation further evaluates the environmental consequences and long-term viability of these materials, placing emphasis on their contribution to addressing water-related difficulties. By integrating the most recent research discoveries and technical progress, this literature review not only provides a thorough examination of sustainable materials used in water treatment, but also emphasises potential directions for further investigation and improvement in this crucial field.
