Closing the loops of material is one of the key ideas behind the foundation of a circular economy (CE). The informal recyclable stations (IRSs) within the solid waste management (SWM) system play an important role as the reversed logistic system, being in charge of collecting and trading recyclable solid waste. This study aimed to comprehend the spatial nature of the system of IRSs in Danang city, Hue city, and Hoi An city as representative sites for the whole of central Vietnam and the nation. The integration of geographic information system (GIS), remote sensing, and statistical learning was performed to clarify spatial characteristics and dynamics of the system of IRSs as well as combat status of limitations of available data in developing countries. Results denoted that the system of IRSs was distributed in close proximity to transportation systems and residential areas with low vegetation coverage. Coverage ratios of the system of IRSs did not strongly fluctuate in case the number of IRSs decreased by 80% regarding the 3500 m distance covered. Negative binomial regression proved to be the most congruent model for understanding the prevalence of IRSs in central Vietnam. Population and normalized difference vegetation index were statistically related to prevalence of IRS. While linear regression depicted balance between variance and bias, support vector machine would be applied if prioritized aim is model performance. The results of this study are a scientific base for the management of the IRS system and the integration of this system into a formal SWM system as well as the transition to a CE.</p>","PeriodicalId":35327,"journal":{"name":"Environmental Quality Management","volume":"34 3","pages":""},"PeriodicalIF":1.5,"publicationDate":"2025-01-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143119697","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The high erosion susceptibility was prevalent in the elevated area and low soil erosion severity was seen in the low-lying plains of the middle and lower reaches. The maximum sediment export (430.16-ton/hectare/year) was noticed in the hills of the Vindhyans, Bundelkhand, and Deccan traps. Contrary to this the low sediment transport was observed in the flat alluvium plains. The conservation practices are slightly more effective in the KRB. Its crop cover reduces the impact of rain's kinetic energy, increase recharge, and mitigates soil erosion.

Carbon nanotubes offer potential therapeutic uses in drug transport, diagnostics, biosensing, and tissue engineering. Fluorescence imaging across the NIR-II range with increased penetration into tissues and spatial precision has shown significant promise in recent years as an effective imaging approach, harnessing the intrinsic band-gap luminescence of semiconducting CNTs. They can penetrate through membranes, delivering medicines, vaccinations, and nucleic acids to previously inaccessible destinations. Thus, the development of innovative and effective drug delivery methods with CNTs can improve the pharmacological properties of many types of medication. Furthermore, the simplicity with which CNTs may be surface functionalized has led to their application as gene delivery vectors for illnesses such as cancer. These vectors include plasmid DNA, miRNA, and siRNA. CNTs, among other carbon nanomaterials, are inherently strong electrical conductors, making them great candidates for interfacing electrically excitable tissues and conducting brain interface investigations. CNT-based hydrogels are commonly utilized for wound healing and antimicrobial purposes. They have shown increased antimicrobial, antibacterial, adhesive, antioxidant, and mechanical capabilities, all of which aids in wound healing. In the field of biomedicine, CNTs are being hailed as promising prospects for both diagnostic and treatment. When it comes to medication distribution, CNTs can help overcome some of the drawbacks of “free” drugs by helping to formulate less water-soluble medications better, enabling targeted delivery, and even facilitating the co-delivery of more than one medication for combination therapy. Currently, two methods attaching the substance being delivered to the exterior sidewalls or encapsulating it within the interior cavities are being investigated for the delivery of medicinal and diagnostic chemicals using CNTs.

This study aims to provide a comprehensive overview of recent developments in CO₂-based polymers, focusing on sustainable biopolymers, including copolymers and polymer blends. A thorough analysis of CO₂ co-polymers as components in polymer blends is conducted, focusing on the capture of CO₂. In recent years, carbon capture technology has attracted considerable focus as a strategy to mitigate the negative effects of increasing CO₂ levels in the environment. The process of developing polymer blends entails merging two or more polymeric substances to harness their distinct advantages. This investigation assessed polyethylene glycol (PEG), polyether sulfone (PES), polyurethane (PU), and polyimide (PI) based on their chemical properties as promising polymer blends for the efficient separation of CO₂.

Nano-fertilizers have high nutrient use efficiency (NUE) and are required in small doses as compared to bulk fertilizers. The use of nano fertilizers in conjunction with a reduced dose of traditional fertilizers improves nutrient availability to plants and minimizes leaching and environmental contamination. The impact of the application of such an integrated fertilization approach on the soil fertility and microbiological population also needs to be understood. The present study investigates the influence of seven field treatments, including biogenic urea nanoparticles, as a source of N nutrient developed by TERI (referred as Teri's nano urea [TNU]), with and without conventional urea in an integrated manner. These treatments include the following: (T1)—100% recommended dose of nitrogen (RDN), (T2)—TNU alone, (T3) 100% RDN combined with TNU, (T4)—TNU at 50% concentration alone, (T5)—75% RDN combined with TNU, (T6) 50% RDN combined with TNU, and (T7) 50% RDN alone. RDF for N, P, and K used in the experiment is 140 kg/ha of urea for nitrogen fertilizer, 60 kg/ha of phosphorus, and 70 kg/ha of potassium in accordance with the local agronomic guidelines. A variable amount of urea was applied in different treatments but the recommended dose of phosphorous and potash fertilizers was applied consistently across the treatments. In different treatments, urea nanoparticles were applied as a nitrogen source via root dipping and foliar spray. The study also incorporates the economics of using nanoparticles to supplement nitrogen in an additive manner along with non-nano macronutrient sources. Further, the influence of this novel approach of fertilization was also evaluated on the native microorganism species found in the rice fields. The results for the evaluated growth parameters, yield parameters, microbial population of soil, plant uptake, and cost economics suggest that at least 25% of the conventional urea requirement can be substituted with urea nanoparticles without causing harm to the bacterial and mycological species found in the rice agricultural fields.</p>\u0000 </div>","PeriodicalId":35327,"journal":{"name":"Environmental Quality Management","volume":"34 3","pages":""},"PeriodicalIF":1.5,"publicationDate":"2025-01-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143114940","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The characteristics of AAS were analyzed using x-ray diffraction (XRD), Fourier transformation infrared spectroscopy (FTIR), SEM, and EDS techniques. The results revealed that AAS had a crystalline structure of calcium silicate hydrate (CSH). The optimal conditions for removing Co²⁺ and Ni²⁺ were found at pH 6, with a contact time of 120 min for individual adsorption and 150 min for simultaneous adsorption. The Langmuir model indicated that the maximum adsorption capacities for individual adsorption were 108.6 mg/g for Co²⁺ and 111.7 mg/g for Ni²⁺. However, in simultaneous adsorption, competition between the metal ions reduced the adsorption capacity, with maximum removal capacities of Co²⁺ and Ni²⁺ on AAS calculated as 58.2 and 72.3 mg/g, respectively. The adsorption of Co²⁺ and Ni²⁺, both individually and simultaneously, best conformed to the Freundlich isotherm model and pseudo-second-order kinetic model. In both the individual and simultaneous systems, the adsorption capacities followed the order of Ni²⁺ &gt; Co²⁺. However, the adsorption process of Ni²⁺ onto AAS was more sensitive than that of Co²⁺, as evaluated by analyzing the effect of Co²⁺:Ni²⁺ concentration ratios on the adsorption process. The potential mechanisms of Co²⁺ and Ni²⁺ removal by AAS included cation exchange, complex formation with surface-active groups, precipitation of new insoluble substances on the adsorbent surface, and competition between metal ions during simultaneous adsorption. The high adsorption efficiency can be attributed to the release of Ca²⁺ and OH⁻ from the CSH crystals. These results suggest that AAS is a promising adsorbent for the removal of Co²⁺ and Ni²⁺ from water.</p>\u0000 </div>","PeriodicalId":35327,"journal":{"name":"Environmental Quality Management","volume":"34 3","pages":""},"PeriodicalIF":1.5,"publicationDate":"2025-01-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143113025","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
