CPCs are cost-effective as they do not need solar tracking, only requiring tilting of the concentrator at intermediate times during a day. In this study, a 3D CPC with reflecting surfaces is strongly simplified by using only two sets of 4 flat mirrors (upper and lower mirrors) arranged in such a way that they form a quadratic funnel. A cylindrical heat absorber made of aluminum is positioned at the base of the funnel and the system is insulated to reduce the heat losses from the system. The purpose of the heat storage is to accumulate heat at sufficient temperatures for cooking. The idea is that a concentrator can be positioned over the heat storage and be replaced by an insulating cover after the heat storage has been charged. Tests with a CPC system is presented here, with test results in outdoor conditions in Trondheim, Norway during the months of May and June. The heat storage reached temperatures of about 135 °C at solar radiation conditions of 500–700 W/m<sup>2</sup>, higher temperatures are to be expected with improved insulation and at sun conditions closer to equator. Previous separate cooking tests have been successfully demonstrated on a similar cylinder for initial heat storage temperatures of 220 °C. A computational model which was tuned to the 220 °C case showed that even an initial temperature of 140 °C can be sufficient for boiling water although at modest amounts of about 1 l.</div></div>","PeriodicalId":100957,"journal":{"name":"Next Energy","volume":"7 ","pages":"Article 100224"},"PeriodicalIF":0.0,"publicationDate":"2024-11-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142748807","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}

In this paper, sulfur electrode materials with different structures of one-dimensional carbon as the carrier and MoS<sub>2</sub> as the catalytic active material are designed by exploring the lithium ions diffusion and electrode reaction behaviors on the cathode surface. Among them, it is found that compared with carbon nanofibers and large-diameter carbon nanotubes, small-diameter carbon nanotubes (SD-CNT) have uniform hollow tubular morphology, abundant micropores, mesopores, and specific surface area, which is not only conducive to containing more active substances but also help the lithium ions diffusion inside the electrode material. Better electrochemical performance is obtained by constructing an interface environment that matches the ionic reaction and diffusion processes. It shows that the first discharge capacity of the obtained SD-CNT@MoS<sub>2</sub>-S cathode is as high as 1144 mAh g<sup>−1</sup>. The capacity retention rate reached more than 92.9% after 100 cycles at 0.5 C rate, further proving that SD-CNT@MoS<sub>2</sub>-S can promote the diffusion of lithium ions and the redox kinetics of sulfur.

Applying phase change materials (PCM) for latent thermal energy storage (TES) systems is an effective method for energy conservation that has been widely considered in recent years. The building facade has the highest capacity for conserving or wasting energy due to its vast exposure to the environment. As a result, a change in attitude toward designing and constructing facades is considered a necessity since it is one of the key elements of building design. One approach to prevent materials from leaching from a structure where PCMs are incorporated is encapsulating and blending them with a suitable polymer. Choosing a PCM with suitable melting temperature, a polymer compatible with this material as a preserver and the best percentage of PCM in the polymer are key components. In this paper, the goal has been investigated through a 2-step process, including experimental and simulation phases. First, the effect of polyethylene glycol (PEG) as the PCM in the mixture with poly methyl methacrylate (PMMA) for heat protection has been studied. Differential scanning calorimetry (DSC) and scanning electron microscopy (SEM) measurement techniques were employed to study and determine the melting points of the samples and the mixed substructures. The results show that the best percentage for PEG in this research is 60%. In the second phase, to study the effect of polymers carrying the PCMs on the building’s energy consumption, a 5-story building with PCMs applied to its facade was simulated in EnergyPlus software. The annual heating and cooling loads of the building in each situation were then calculated. The results of the simulation and modeling shows that applying the PCMs will ultimately lead to a 40% decrease in heating load and 15% decrease in cooling load of the building.</div></div>","PeriodicalId":100957,"journal":{"name":"Next Energy","volume":"6 ","pages":"Article 100210"},"PeriodicalIF":0.0,"publicationDate":"2024-11-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142663611","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}
