Here, we tackle this key issue by equipping the PCP photoanode with ferroelectric single-domain PbTiO3 nanoplates, which can form a directional “macroscopic electric field” throughout the entire photoanode controllable by external polarization. The properly poled PCP photoanode allows the photogenerated electrons and holes to migrate in opposite directions, that is, electrons to the protected metal and holes to the photoanode/electrolyte interface, leading to largely suppressed charge annihilation and consequently a considerable boost in the overall solar energy conversion efficiency of the PCP system. The as-fabricated photoanode can not only supply sufficient photocurrent to 304 stainless steel to initiate cathodic protection, but also shift the metal potential to the corrosion-free range. Our findings provide a viable design strategy for future high-performance PCP systems based on ferroelectric nanomaterials with enhanced charge flow manipulation.","PeriodicalId":100403,"journal":{"name":"Electron","volume":"2 3","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-06-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/elt2.51","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142100059","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}

Nguyen, Ming Shao","doi":"10.1002/elt2.52","DOIUrl":"https://doi.org/10.1002/elt2.52","url":null,"abstract":"Despite their excellent intrinsic stability, low-dimensional Ruddlesden-Popper (LDRP) perovskites face challenges with low power conversion efficiency (PCE), primarily due to the widen bandgap and limited charge transport caused by the bulky spacer cation. Herein, we introduce formamidinium chloride (FACl) as an additive into (4-FPEA)2MA4Pb5I16 perovskite. On the one hand, the addition of FACl narrows the bandgap through cation exchange between MA+ and FA+, thereby extending the light absorption range and enhancing photocurrent generation. On the other hand, this MA+/FA+ cation exchange decelerates the sublimation of methylammonium chloride and prolongs the crystallization of LDRP perovskite, leading to higher crystallinity and better film quality with a decreased trap-state density. Consequently, this approach led to a remarkable PCE of 20.46% for <n> = 5 LDRP perovskite solar cells (PSCs), ranking among the highest for MA/FA mixed low dimensional PSCs reported to date. Remarkably, our PSCs maintained 90% and 92% of the initial efficiency even after 1300 h at (60 ± 5)°C and (60 ± 5)% relative humidity, respectively. This work promotes the development of LDRP PSCs with excellent efficiency and environmental stability for potential commercial application.","PeriodicalId":100403,"journal":{"name":"Electron","volume":"2 3","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-06-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/elt2.52","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142099988","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}

This characteristic is extensively utilized in various electronic memory and computational devices, particularly as selectors for cross-point memory architectures. Despite its advantages, the material is susceptible to glass relaxation, which can result in substantial drifts in threshold voltage and a decline in off-current performance over successive operational cycles or long storage time. In this study, we introduce an OTS device made from stoichiometric Sb2Se3 glass, which retains an octahedral local structure within its amorphous matrix. This innovative material exhibits outstanding OTS capabilities, maintaining minimal degradation despite undergoing over 107 operating cycles. Via comprehensive first-principles calculations, our findings indicate that the mid-gap states in amorphous Sb2Se3 predominantly stem from the atomic chains characterized by heteropolar Sb-Se bonds. These bonds exhibit remarkable stability, showing minimal alteration over time, thereby contributing to the overall durability and consistent performance of the material. Our findings not only shed light on the complex physical origins that govern the OTS behavior but also lay the groundwork for creating or optimizing innovative electrical switching materials.","PeriodicalId":100403,"journal":{"name":"Electron","volume":"3 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-06-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/elt2.46","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141336834","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 emergence of machine learning (ML) and artificial intelligence (AI) has led materials scientists to recognize the potential of using AI/ML to accelerate the creation of new battery materials. Although fixed material properties have been extensively studied as descriptors to establish the link between AI and materials chemistry, they often lack versatility and accuracy due to a lack of understanding of the underlying mechanisms of AI/ML. Therefore, materials scientists need to have a comprehensive understanding of the operational mechanisms and learning logic of AI/ML to design more accurate descriptors. This paper provides a review of previous research studies conducted on AI, ML, and descriptors, which have been used to address challenges at various levels, ranging from materials development to battery performance prediction. Additionally, it introduces the basics of AI and ML to assist materials and battery developers in comprehending their operational mechanisms.

The nitrogen reduction reaction (NRR) technology has garnered a lot of attention lately because of its benefits, which include being environmentally friendly, sustainable, and able to function in mild environments. However, NRR is still in its early stages of development and confronts numerous difficult issues, including slow reaction kinetics, low ammonia yield rates and Faradaic efficiency (FE), and a dearth of effective research on nitrogen fixation as a whole. This paper aims to promote the industrialization of NRR, summarizing the progress of iron-based catalysts, including single atomic catalysts, organic frameworks, metal oxides the, and alloys. Eventually, this paper discusses the strategies for improving NH3 yield rates and FE, improving reaction kinetics, and building a sustainable overall nitrogen fixation system.

The focus of this review article is to shed light on the different modalities of hybrid nanoparticles, providing a concise description of hybrid silver nanoparticles, exploring various modes of synthesis and classification of hybrid silver nanoparticles, and highlighting their advantages. Additionally, we discussed core-shell silver nanoparticles and various types of core and shell combinations based on the material category, such as dielectric, metal, or semiconductor. The two primary classes of hybrid silver nanoparticles were also reviewed. Furthermore, various hybrid nanoparticles and their methods of synthesis were discussed but we emphasize silica as a suitable candidate for hybridization alongside metal nanoparticles. This choice is due to its hydrophilic surface qualities and high surface charge, which provide the desired repulsive forces to minimize aggregation between the metal nanoparticles in the liquid solution. Silica shell encapsulation also provides chemical inertness, robustness and the adaptability to the desired hybrid nanoparticle. Therefore, among all the materials used to coat metal nanoparticles; silica is highly approved.","PeriodicalId":100403,"journal":{"name":"Electron","volume":"2 2","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-05-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/elt2.22","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141102490","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}
