Ultra-deep fractured tight gas reservoirs were susceptible to be damaged owing to geological conditions and engineering status. Taking the ultra-deep fractured tight gas reservoirs located in the Tarim Basin as an example, ultra-tight, high-pressure, high temperature (HPHT), and high-salinity formation water, ultra-low water saturation and fracture networks were identified as special geological characteristics. High-density oil-based drill-in fluids and serious lost circulation were the special engineering status. Challenges in laboratory experiments to evaluate formation damage include rigorous experimental conditions and unsuitable experimental methods. In addition, improving the formation protection ability of working fluids and minimizing the formation damage induced by the sequential use of different types of working fluids were the main challenges associated with using working fluids. Challenges in lost circulation control include the failure of plugging zone due to the degradation of lost circulation materials and repeated lost circulation due to the strength reduction of the plugging zone soaked in diesel oil. Recommendations for key technologies to improve targeted formation damage control technology have been proposed. The comprehensive analysis of these issues provides a road-map for researching formation damage control technologies.</p></div>","PeriodicalId":100960,"journal":{"name":"Next Sustainability","volume":"4 ","pages":"Article 100046"},"PeriodicalIF":0.0,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2949823624000230/pdfft?md5=55200755a2f14b553ee27ee5a51408cc&pid=1-s2.0-S2949823624000230-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140880458","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}

This is primarily attributed to the demand for occupant comfort, encompassing air-conditioning, lighting, and electrical usage. In response to this pressing challenge, switchable smart windows have emerged as a highly promising solution applicable to both residential and commercial structures. By effectively modulating light and heat, these windows offer a multifaceted approach to energy conservation, encompassing reduced heat loss, diminished reliance on artificial lighting, and consequential cost savings. This research paper critically evaluates the latest advancements in electrically actuated smart windows, with a specific focus on AC-powered variants such as Suspended Particles, Liquid Crystal, and DC-powered Electrochromic windows. The study meticulously delves into the operational principles, technical parameters, advantages, limitations, prospects, applications, energy-saving potential, and market penetration of these intelligent window technologies. Notably, the investigation extends to key thermal metrics like overall heat transfer coefficient and solar heat gain coefficient, alongside optical attributes including correlated colour temperature (CCT) and colour rendering index (CRI). Furthermore, the report delves into the intricate challenges associated with integrating smart windows into building infrastructure, presenting viable solutions and perspectives to address these concerns. These challenges encompass the absence of standardized regulations within the UK, elevated costs, technical intricacies, limited research and development, and uncharted compatibility with both new constructions and retrofit designs. Through a comprehensive analysis, this paper endeavours to shed light on potential avenues to surmount these obstacles, ultimately unlocking the full potential of smart windows in establishing energy-efficient built environments.</p></div>","PeriodicalId":100960,"journal":{"name":"Next Sustainability","volume":"3 ","pages":"Article 100027"},"PeriodicalIF":0.0,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2949823624000047/pdfft?md5=c75cedd593f0d90384c1761e69e3ce94&pid=1-s2.0-S2949823624000047-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139699987","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}

NONPs are further categorized based on their location in the environment, such as Naturally Occurring Carbon Nanoparticles, Naturally Occurring Metal Nanoparticles, NONPs present in food, NONPs of biological origin and NONPs present in the aquatic environment. NONPs exhibit ubiquity, spanning the atmosphere, hydrosphere, lithosphere and biosphere. They exhibit distinct properties in comparison to their bulk counterparts, such as a substantial surface area-to-volume ratio, immune-boosting capabilities, scavenger activity, nutritional significance and electron-donor attributes. NONPs have been utilized by humans since ancient times. Owing to these properties, they have been used unknowingly in various fields like medicine, cosmetics, decor, textile and the food industry. NONPs are found in artifacts such as Copper Ruby and the Lycurgus Cup, as well as in medicine, cosmetics and the food industry. Even today, NONPs continue to play pivotal roles in diverse fields such as cancer treatment, biosensors and the food industry. Also they contribute to environmental processes, soil fertility, nutrient transport and bioremediation. This review sheds light on multifaceted significance of NONPs in our evolving scientific landscape and comprehensively explores the history, sources, properties, types and uses of NONPs.

A Taguchi design approach was employed to determine the optimal conditions for the RBBR adsorption onto SRTLAC.

The maximum removal of 246.5 mg/g was attained at the highest initial RBBR concentration of 120 mg/L, solution pH of 2, sorbent dosage of 20 mg, and agitation time of 110 min. The analysis of variance results showed that RBBR initial concentration contributed the most significant percentage (95.33 %) towards the removal uptake, highlighting its considerable impact. The adsorption data collected at various concentrations (20 – 120 mg/L) were modelled using three non-linear regression isotherms and kinetic models. The Langmuir isotherm model provided the optimal fit for adsorption, suggesting a monolayer and homogenous sorption system with a maximum capacity of 491.38 mg/g. Meanwhile, the pseudo-2^nd order kinetic models accurately elucidated the sorption mechanism.
