However, the rapid capacity degradation resulting from its significant volume expansion remains a critical challenge. Herein, an innovative binder system for micro-sized Si anodes is presented. Utilizing a high-energy ball milling reaction, Si particles are coated with a thin polydopamine (PDA) layer, forming Si@PDA particles. Subsequently, a polyvinyl alcohol (PVA) binder is incorporated to form the Si@PDA/PVA binder system. The numerous hydroxyl groups in PDA form hydrogen bonds with PVA binder, establishing robust interactions among electrode components, thereby stabilizing the overall structure of the Si anode and maintaining the integrity of its electrical contacts. As a result, the obtained Si@PDA/PVA anode exhibits a high specific capacity of 1215 mAh g−1 at 0.2 C after 100 cycles. In addition, the rate performance test demonstrates that it delivers a high capacity of over 800 mAh g−1 at 3 C. This approach provides a promising strategy for the overall design of micro-sized Si electrodes, offering enhanced cyclic performance and durability.","PeriodicalId":11573,"journal":{"name":"Energy technology","volume":"13 4","pages":""},"PeriodicalIF":3.6,"publicationDate":"2024-12-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143793770","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The high-energy consumption associated with this process has motivated the pursuit of alternative approaches to process raw biogas at lower operating temperatures and without the need for large amounts of steam to prevent catalyst deactivation. The present study discusses the results obtained for the steam reforming of raw biogas in the presence of electric fields, using a nanocomposite catalytic material prepared by physically mixing yttria-stabilized zirconia and a Ni/Al2O3 catalyst. The experiments are conducted using a parallel plate capacitor reactor operated at 700 °C and 1 atm. The results indicate that by applying an external electric field (EEF) with a DC voltage of 1.9 kV and a current of 9 mA, a substantial increase in the rates of reaction can be attained. The conversions obtained for CH4 and CO2 are higher than the equilibrium values calculated in the absence of an EEF by 23% and 17%, respectively. This shift in the equilibrium is attributed to internal electric fields (IEFs) resulting from the interaction between YSZ and Ni/Al2O3, which leads to the creation of an interfacial nanopore structure that could increase the local IEF strength.","PeriodicalId":11573,"journal":{"name":"Energy technology","volume":"13 4","pages":""},"PeriodicalIF":3.6,"publicationDate":"2024-12-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/ente.202401074","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143793845","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The nanocapsules are produced via multiple crystallization precipitations from a saturated erythritol aqueous solution, followed by SiO2 coating using a sol–gel method. Their nanostructure and elemental composition are characterized using scanning electron microscopy and energy-dispersive X-ray spectroscopy. The latent heat of the nanocapsules is measured with a differential scanning calorimeter. The erythritol nanocapsules, with an average size of ≈220 nm, exhibit a melting enthalpy of 192.7 J g−1. Notably, the supercooling degree of the nanocapsules is reduced by ≈30.0 °C compared to pure erythritol. After 200 thermal cycles, the heat storage performance of the nanocapsules shows only a 7.6% decrease. A latent heat functional thermal fluid, suitable for high-temperature heat transfer, is prepared by dispersing the nanocapsules in silicone oil. The thermal conductivity and specific heat capacity of this fluid increase by 20.5% and 283.3%, respectively, compared to pure silicone oil.

Photosynthetic pigments in plants, algae, and cyanobacteria have remarkably higher quantum efficiencies than corresponding synthetic and semisynthetic materials used in photovoltaic cells. The antioxidative and intrinsic properties of natural pigments like carotenoids make them suitable for new-generation sustainable energy and green electronics applications. In this computational study, an attempt has been made to understand the scope of carotenoids as an additive to the active layer and/or eco-friendly alternatives to the hole transport materials (HTM) like Spiro-MeOTAD in preparing perovskite solar cells. Accordingly, quantum and moleculer mechanical simulations are done to evaluate and compare the optoelectronic parameters of some easily available carotenoids vis-à-vis some noncarotenoids like betacyanin, xylindein, and Spiro-MeOTAD. HOMO–LUMO energy levels of carotenoids aligned well with those of perovskite. In addition, their light absorption spectra are also found to be complementary, and hence, the carotenoids can exhibit tandem behavior in absorbing visible light along with perovskite materials. Hole reorganization energies (λ) of some carotenoids like capsorubin, capsanthin, and violaxanthin are almost equivalent to Spiro-MeOTAD's. Calculated glass transition temperatures (Tg) of carotenoids indicate their thermophysical stability during peak summer.","PeriodicalId":11573,"journal":{"name":"Energy technology","volume":"13 4","pages":""},"PeriodicalIF":3.6,"publicationDate":"2024-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143793871","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Second, a multiobjective cost function is constructed to consider hydrogen consumption cost, power consumption cost, fuel cell lifespan, and power battery lifespan. Finally, a comprehensive dynamic decision Q network (CDDQN) framework based on double deep Q network (DDQN) is established, a series of deep reinforcement learning EMS that integrate CDDQN with SOC trajectory control are designed, and they are validated through experimental analysis. The results demonstrate that this strategy exhibits excellent real-time performance and economic efficiency.

Platinum-based electrodes commonly used in the cathode of MFCs pose a significant cost barrier, necessitating advancements in electrode materials for practical, large-scale application.

An MFC configuration utilizing nitric acid-treated carbon felt as the anode and an oak-derived carbon electrode as the cathode effectively treat wastewater and convert CO2 to methane, yielding a power density of 5.5 mW m−2 and Coulombic efficiency of 7.3%, approximately twice those without nitric acid treatment and surpassing even the performance of the system with BES treatment.
