Herein, a novel zinc complex (Zn[MTA]<sub>n</sub>) was prepared and found to be extremely efficient in the presence of Zn-N acid-base active pairs. The combination of catalyst characterization, experiments and density functional theory (DFT) calculations reveals that Lewis acidity of Zn sites on Zn[MTA]<sub>n</sub> is effectively activated and enhanced to facilitate the adsorption of electron pair on the aldehyde group of glucose, in addition, the proton on C2 position of glucose is extracted more quickly by the basic N active sites on 3-methyl-1H-1,2,4-triazole (MTA) ligand adjacent to Zn site. Consequently, Zn[MTA]<sub>n</sub> with acid-base bifunctional Zn-N active pairs provided an outstanding fructose yield with the highest selectivity among all heterogeneous catalytic systems to date. Furthermore, a cyclic conversion strategy was developed for the highly selective synthesis of 5-hydroxymethylfurfural (HMF) from glucose through fructose in a water/MIBK biphasic media. In each cycle, ∼45 % glucose was consumed to HMF with a minor loss of carbon balance, which is a valuable and referential approach for the industrial production of HMF from glucose.</div></div>","PeriodicalId":419,"journal":{"name":"Renewable Energy","volume":"250 ","pages":"Article 123382"},"PeriodicalIF":9.0,"publicationDate":"2025-05-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143942805","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The hemispherical emissivity model (HEM) is a widely used physical model for calculating the surface temperature of radiative cooling coatings; however, its reliance on fixed radiative properties limits its long-term accuracy. To solve this problem, this study used bidirectional long short-term memory (Bi-LSTM) and encoder-Transformer (E-T) models to capture the dynamic changes in the cooling performance. Subsets containing 20%–50% of the original training dataset's size were used to validate the impact of the small-batch training dataset. An automatic hyperparameter optimization strategy was also proposed to determine the optimal hyperparameter combination. The results demonstrated that across all training ratios, both the Bi-LSTM and E-T outperform HEM, with E-T providing the highest accuracy. The E-T model, within the 20%–50% training ratio range, exhibited the root mean squared error (RMSE), mean absolute error (MAE) and coefficient of determination (R<sup>2</sup>) ranging from 1.24°C to 1.58°C, 0.94°C to 1.26°C, and 0.92 to 0.95, respectively.

In this context, very few studies have investigated the potential of these technologies in Southern Mediterranean regions, characterized by predominant cooling demands and large availability of renewable energies. In this respect, this work proposes an energy analysis of modern district networks composed of solar collectors, absorption chillers, heat pumps, and thermal energy storage, serving a cluster of buildings in Southern Italy. Using a dynamic model for a double-loop ring network and solar plant developed in Transient System Simulation tool, different scenarios are simulated. Specifically, a baseline scenario, where thermal demand is met individually, is compared with low-temperature (60–85 °C) and ultra-low-temperature (7–20 °C) networks. An examination of primary energy consumption, carbon dioxide emissions, temperatures, and pressure within the network reveals that the proposed improvement scenarios lead to energy savings respectively from 62% to 82% compared to autonomous heating and cooling systems. Additionally, ultra-low temperature district reduces heat losses in pipes by 67.4% compared to low-temperature operation. However, the energy needed by booster heat pumps in the case of an ultra-low temperature network leads to higher primary energy consumption of a factor of 2.1 compared to the case of a low-temperature network.

Therefore, this paper proposed a novel compressed CO<sub>2</sub> energy storage and compression heat underground storage system using multi-stage hydraulic fractures of the horizontal well in depleted oil and gas reservoirs to solve the above problems. Based on the novel system numerical model considering multiphase flow processes, the unique spatiotemporal evolution of key physical fields in this new system during the cushion and circulation stages was analyzed, which is unknown from previous studies. The round-trip efficiency was preliminarily calculated, and unique advantages of this novel system were discussed. Results show that hydraulic fractures improve fluid flow performances. High saturation zones of 0.5–0.7 formed around fractures and horizontal well are main working areas, which is markedly different from the characteristic of having a well-defined boundary within the cavern, but is stable enough during simulation periods.
