The effect membrane dosage, temperature, ionic strength, contact time, pH and initail concentration on EBT adsorption was illustrated. Adsorption capacity (q_e) was enhanced from 7.32 to 12.71, 1.77 to 12.71, 6.71 to 12.71, and 16.16 to 17.39 mg/g with membrane dosage (mass), initial concentration, contact time, and ionic strength respectively while decreased from 12.71 to 3.77 and 12.71 to 3.65 mg/g with temperature and pH of medium respectively. Adsorption of EBT was subjected to various adsorption isotherms including Langmuir, Freundlich, Temkin and Dubinin-Radushkevich (D-R) models. It was noticed that EBT adsorption obeyed Freundlich isotherm because the value of correlation coefficient (R² = 0.991) was close to unity. Several kinetics models were utilized to demonstrate EBT adsorption. Results showed that EBT adsorption fitted to pseudo-second order (PSO) model because the value of correlation coefficient (R² = 0.997) was close to unity. Adsorption thermodynamics study represented that EBT adsorption onto the DF-120 commercial AEM was an exothermic process (ΔH°= −79.78 KJ/mol). In addition, the regeneration of DF-120 commercial AEM was also studied.</p></div>","PeriodicalId":100957,"journal":{"name":"Next Energy","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2949821X24000012/pdfft?md5=6f86f5157def907c859fce3a81521d92&pid=1-s2.0-S2949821X24000012-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140342132","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}

Thus, to the best of our knowledge, here we summarize and discuss a comprehensive list of most current and potential applications of passive daytime radiative cooling to broaden horizons in this technology. First, from a materials perspective, we briefly summarize approaches to creating high solar reflectance and high emissivity in the atmospheric window of 8–13 µm. We then present applications in five major categories, each with several sub-categories, and discus each application with selective articles. Based on the availability of real-world demonstrations and developments in commercialization, we qualitatively assess the technology readiness levels of these applications, highlighting future directions that need more attention.

This map has been classified into five categories namely, restricted zone, less suitable zone, moderate suitable zone, good suitable zone, and excellent suitable zone. These categories are covered by 7.28%, 16.61%, 28.51%, 27.77%, 21.83% land of total area in Bangladesh respectively. The findings of this research have been presented that ‘the excellent suitable’ and ‘good suitable’ areas for the construction of solar power plants are in the western and northwestern part (Rajshahi, Pabna, Sirajganj, Natore, Naogaon, Chapainawabganj, Bogura, Faridpur, Jessore, Jehenaidha, Magura, Kushtia, Choudanga, Meherpur) of the study area which contain a high value of global horizontal irradiation, direct normal irradiation, elevation and low value of slope, rainfall, temperature, relative humidity. Besides the restricted and less suitable zone for installing solar photovoltaic (PV) power plants indicates a high value of rainfall, slope, temperature, relative humidity and low value of global horizontal irradiation, direct normal irradiation, and elevation. Bangladesh's currently operational solar plants were taken into consideration for this study's validation purposes.

Given the inherent difficulty in accurately measuring film thickness and the inability to test optical constants in situ, we employ a semi-self-supervised learning strategy and train the model exclusively using experimental twin spectral data generated by VO₂-based smart radiation devices (SRDs) during the thermal phase transition process. Our proposed model exhibits remarkable proficiency in capturing spatial distribution information pertaining to material characteristics in multilayer systems possessing thermochromic phenomena. Additionally, it demonstrates exceptional accuracy in predicting the radiation regulation performance of such systems.

Considering the relative maturity of electrode materials, researchers generally pay attention to the electrolyte and corresponding electrode/electrolyte interphase in order to accelerate ion transport. In light of significant advancements, we herein try to delineate and categorize the electrolyte engineering to depict what next can be done to build better batteries suitable for cooler temperatures in the near future. Specifically, advances in electrolyte engineering are summarized with the goal of improving ionic conductivity in bulk electrolyte, facilitating desolvation dynamics at the electrode/electrolyte interface, and accelerating ion movement across the interfacial film.

However, the insufficient catalytic capacity and poor durability of the oxygen electrodes in solid oxide cells (SOCs) at intermediate temperatures pose a huge challenge for SOCs applications. In this work, A-site deficient La_0.77Sr_0.2Co_0.2Fe_0.8O_3-δ nanorod materials coated with Ce_0.8Gd_0.2O_1.9 (GDC) are prepared to suppress cation surface segregation and enhance charge transfer kinetics by reducing internal elastic force of perovskite and meanwhile applying external compressive stress with an oxygen-ion conductor. As a result, the composite cathode with a GDC to La_0.77Sr_0.2Co_0.2Fe_0.8O_3-δ weight ratio of 0.59 (La_0.77Sr_0.2Co_0.2Fe_0.8O_3-δ@GDC0.59) exhibits excellent electrochemical performance and long-term stability when operating in both SOFCs and SOECs modes. XPS results show that the La_0.77Sr_0.2Co_0.2Fe_0.8O_3-δ@GDC0.59 oxygen electrode exhibits no significant Sr/Fe surface segregation after operating in SOFCs and SOECs modes for 200 h. Density functional theory calculation and physiochemical characterization confirm that Sr segregation phenomenon is well inhibited through the novel A-site deficient structural design of perovskite materials, which eliminates the major residual internal elastic force of La_0.8Sr_0.2Co_0.2Fe_0.8O_3-δ crystal, and GDC coating further relieves the lattice transformation of La_0.77Sr_0.2Co_0.2Fe_0.8O_3-δ upon the additional introduction of A-site deficiency and oxygen vacancy.
