... Synthetic rubber also relies on pigments to provide specific colors for products like tires, seals and gaskets helping to distinguish them and sometimes to indicate particular properties. These aromatic compounds, while contributing to the aesthetic appeal of products, can also act as toxic pollutants with far-reaching consequences [6][7][8]. One of the major concerns associated with these colorants is their potential to induce cardiovascular issues [9]. ...

... For example, the development of sustainable livelihoods for local communities that are based on the conservation and utilization of wetland resources with an understanding of biomechanical principles can ensure the long-term viability of these ecosystems. The promotion of ecotourism activities that highlight the biomechanical wonders of wetlands can raise public awareness and support for conservation efforts [33]. ...

... The process of altering the surface of nanoparticles is frequently used to improve their stability and dispersion in the base fluid, which can enhance the nanofluid's thermal performance. The purpose of this work is to investigate how various surface alterations of silver nanoparticles affect heat pipe thermal performance [3]. ...

... Regarding the persistence and biodegradability of emerging contaminants, many of these compounds are resistant to biodegradation and can persist in the environment, posing an additional challenge for their effective removal [142]. This is because they are often not removed by conventional biological processes, requiring advanced technologies such as reverse osmosis [143]. While some traditional pollutants are also persistent, they are, however, more susceptible to biological degradation processes, which can facilitate their removal in conventional treatment systems [144]. ...

... New carbonaceous biosorbents have been fabricated from biomass and biowaste to efficiently remove Cr(VI) from aqueous systems. [10][11][12][13][14][15][16] Electrostatic attraction and complexation with the oxygen (O)-containing functional groupssuch as carboxyl, phenolic hydroxyl, carbonyl, anhydride, etc.on the surface of BC activated carbon surfaces, provides the adsorption sites for heavy metals. 17 For instance, apricot stones carbonized then activated with sulfuric acid (H 2 SO 4 ) exhibited a Cr(VI) uptake capacity of 34.70 mg g −1 . ...

... The possibilities of traditionally used sorbents (activated carbon, silica gel, expensive ion exchange resins, etc.) have been largely exhausted; therefore, research on their use consists of creating modified sorbents with improved practical characteristics by changing the properties of the sorbent surface. The ability of natural zeolite minerals to extract various heavy metals (mainly from aqueous solutions), due to their structure and physico-chemical properties, has long been known and widely used [10][11][12][13]. Natural zeolites are crystalline aluminosilicates of alkaline and alkaline earth metals having a "frame" structure, with cavities and channels that determine molecular sieving, sorption and other properties. ...

... Furthermore, electrochemical techniques are adaptable, allowing for the simultaneous detection of multiple pollutants and the use of tailored electrode materials to enhance selectivity and sensitivity, making them an excellent choice for NB determination in a variety of environmental and industrial circumstances. [27][28][29][30][31][32] Establishing oligomer and anisotropic oligomer-capped gold nanostructures (AuNS) with 3-amino-5-mercapto-1,2,4-triazole (AMTa) as a monomer is the purpose of this investigation. The developed oligo AMTa and oligo AMTa-AuNS were subsequently investigated on glassy carbon (GC) electrodes for their electrocatalytic performance of NB reduction. ...

... The incorporation of Artificial Intelligence (AI) in water-based applications treatment offers notable advantages, such as improved effectiveness, anticipatory maintenance, and optimized allocation of resources considering the global demand for clean water and sustainable systems. Despite challenges caused by system complexity, variable instrumentation levels, dimensions of the WWTP and data quality issues, an emerging approach to addressing this issue is to exploit development in data science and modelling (Wang et al., 2021(Wang et al., , 2023a(Wang et al., , 2023bAlam et al., 2022;Senthil Rathi et al., 2024). In water and wastewater treatment sectors, for environment-health-safe point of vu, generated pollution and by-products must be appropriately managed in respect to applied standards and regulation. ...

... The inclusion of biochar in broiler feed has significant benefits, including enhanced digestion, improved growth rate, better feed conversion ratio (FCR), and increased feed efficiency, which maximizes the energy absorbed from feed. Biochar effectively binds toxins, mitigating their adverse effects on the digestive system and intestinal flora (Sivaranjanee et al., 2024). These properties were evident in this study, where birds supplemented with biochar from maize stover (T3) demonstrated superior performance in final body weight, body weight gain, and average daily weight gain. ...
