A two-dimensional reactor model was developed integrating electromagnetic field coupling with MSR reactions, fluid dynamics and heat transfer. In the reactor, heat is induced instantaneously on the magnetic material through an electromagnetic induction process, which generated by renewable electricity. Results showed that the Internal - Double Row Cylinder (IN-DRC, cylinder means that the shape of induction heating element is cylindrical.) highest heating efficiency is 38.3%, which is limited by the kinetics of MSR reaction. Here, thermal efficiency reaches its maximum with the reaction channel outlet temperature reaching about 580 K. Internal - Double Row Cylinder (IN-DRC) and Internal - Double Row Ball (IN-DRB, ball means that the shape of induction heating element is spherical) methanol conversions are virtually identical, with a maximum value close to 100%. Furthermore, the findings that the adoption of internal induced heating, in contrast to external heating, across the four reactor designs can effectively mitigate temperature gradient within the reactors. This reduction in thermal disparity significantly amplifies methanol conversion within the reactor, thereby markedly enhancing its overall performance in hydrogen production.Therefore, non-contact internal induction heating method has the potential for substantially hydrogen production processes.</div></div>","PeriodicalId":100356,"journal":{"name":"DeCarbon","volume":"6 ","pages":"Article 100075"},"PeriodicalIF":0.0,"publicationDate":"2024-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142426682","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}

Nevertheless, the use of LIBs in renewable energy storage applications is challenging due to their limited power densities. To comprehend the origin of this limitation, it is crucial to investigate the effect of electrode architecture on the Li⁺ ion transport within their pores (solution-phase). In this work, the solution phase transport in various porous Li₄Ti₅O₁₂ (LTO) films was investigated using scanning ion conductance microscopy (SICM) and scanning electrochemical microscopy (SECM). When the porosity of LTO film increases, SECM and SICM approach curves show an increase in current. This is attributed to the ion transport through the film pores. The 2D topographical mapping using both techniques shows their ability to detect the LTO film's heterogeneity. Most importantly, this work gives insight into the complementary nature of the two scanning probe techniques as demonstrated by the comparable MacMullin numbers.</p></div>","PeriodicalId":100356,"journal":{"name":"DeCarbon","volume":"6 ","pages":"Article 100073"},"PeriodicalIF":0.0,"publicationDate":"2024-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2949881324000398/pdfft?md5=4bb8fdc9af33243c06ba30fffb97d7e6&pid=1-s2.0-S2949881324000398-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142230690","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}

The effect of the modification of the manganese oxide with STA on its surface is determined. It is shown that MnO₂ modified with STA exhibits better cumulative high specific surface areas and mesoporous volumes areas.

Subsequently, three common work modes of droplet-based TENGs are introduced, and the energy harvesting process and the maximum efficiency of DEG which possess the droplet-characteristic feature are detailed description. Additionally, the performance and advantages of droplet-based TENGs are outlined, followed by a summary of strategies aimed at enhancing the output performance of droplet-based TENGs.

In this review, we intend to summarize the advances and challenges in the understanding of the electrocatalytic OER at LCD. Initially, the impact of LCD on the electron transfer, mass transportation efficiency and catalyst stability is identified and summarized. Furthermore, five basic principles for catalyst design, namely the dimension of the materials, surface chemistry, creation of electron transfer pathways, synergy among nano-, micro-, and macroscale structures, and catalyst-support interaction, are systematically discussed. Specifically, the correlation between the synergistic function of the multiscale structures and the catalyst-support interaction is highlighted to direct improvements in catalyst efficiency and durability at the LCD.
