The construction of an artificial solid electrolyte interphase layer featuring high ionic and low electronic conductivity has been verified to be a high-performance strategy to confine the dendrite growth and promote the Li anode stability. Therefore, a functional organic protective layer is homogeneously deposited on the Li anode surface via an in situ chemical reaction between tetracyanoquinodimethane (TCNQ) and Li. The as-synthesized Lin-TCNQ organic film could efficiently trap non-uniform Li deposition and restrain dendrite propagation. Particularly, an asymmetric M-TCNQ-Li|Cu cell with the Lin-TCNQ layer breezed through a high Coulombic efficiency of 91.15% after 100 cycles at 1.0 mA cm−2. The M-TCNQ-Li|NCM622 cell delivered a high capacity of 143.40 mAh g−1 at 0.2 C and maintained a good cyclic stability of 110.44 mAh g−1 after 160 cycles. The analysis results of spectroscopic tests further demonstrate that the Lin-TCNQ with the enhanced absorption energy is conducive to lithiophilicity and decreases the overpotential of Li deposition.","PeriodicalId":100403,"journal":{"name":"Electron","volume":"2 4","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-10-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/elt2.72","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142753987","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 work, the influences of neutron radiation-induced defects on the SC capability and reliability of SiC P-intrinsic-N (PiN) diodes were comprehensively investigated. It was found that the surge capability of the diodes can be deteriorated even under the slightly enhanced formation of carbon-vacancy-related Z1/2 and EH6/7 defects introduced by neutron irradiation. Surprisingly, it was found that the forward voltage (VF) decreases with the increased SC and the stress cycles in the irradiated diodes, which is usually found to increase under the SC tests and attributed to the bipolar degradation (BPD). By using technology computer-aided design simulation and deep-level transient spectroscopy characterization, it was found that the significant self-heating during surge stress leads to the annealing effect on the Z1/2 defects through the promoted recombination with the nearest and second neighbor carbon interstitials injected by irradiation, which thus plays a dominant role in the decrease of VF over the BPD.","PeriodicalId":100403,"journal":{"name":"Electron","volume":"3 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-10-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/elt2.64","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143535852","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 review focuses on recent developments in smart, self-sensing fiber-reinforced composites incorporating nanomaterial-coated piezoresistive fabric sensors such as carbon nanotubes (CNTs), graphene, and MXene. A comprehensive overview of process monitoring involving the complete resin infusion cycle, such as compaction response, resin flow monitoring, pressure variations within the mold, process-induced defects monitoring, and cure/post-cure monitoring, has been provided. The post-manufacturing structuring health monitoring (SHM) of composites has also been discussed in detail. An overview of the associated challenges of these sensors, such as manufacturability, robustness, conductivity/piezoresistivity calibration, and the effect on structural integrity, is presented.

The cubic spinel NCs, terminated with exclusive {100}-facets, demonstrate superior electrocatalytic activity for the oxygen reduction reaction (ORR) in alkaline media compared to their octahedral and concave cubic counterparts. Specifically, at 0.85 V, (CoMn)Fe2O4 spinel oxide nanocubes achieve a high mass activity of 23.9 A/g and exhibit excellent stability, highlighting the promising ORR performance associated with {100}-facets of multi-metal spinel oxides over other low-index and high-index facets.

Traditional disposal methods such as landfilling and incineration not only exacerbate environmental degradation by releasing harmful chemicals and greenhouse gases, but also squander finite resources that could otherwise be recycled or repurposed. Upcycling is a kind of plastic recycling technology that converts plastic waste into high-value chemicals and helps to avoid resource waste and environmental pollution. Electrocatalytic upcycling emerges as a novel technology distinguished by its mild operational conditions, high transformation efficiency and product selectivity. This review commences with an overview of the recycling and upcycling technology employed in plastic waste management and the respective advantages and inherent limitations are also delineated. The different types of plastic waste upcycled by electrocatalytic strategy are then discussed and the plastic waste transformation process is examined together with the mechanisms underlying the electrocatalytic upcycling. Furthermore, the structure-activity relationships between electrocatalysts and plastic waste upcycling performance are also elucidated. The review aims to furnish readers with a comprehensive understanding of the electrocatalytic techniques for plastic waste upcycling and to provide a guidance for the design of electrocatalysts towards efficient plastic waste transformation.","PeriodicalId":100403,"journal":{"name":"Electron","volume":"2 3","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-08-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/elt2.63","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142099971","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}
