The investigation focuses on three lattice parameters (a = 4.23 Å, 4.187 Å, and 4.183 Å) to explore how lattice strain influences the electronic band structure, density of states (DOS), quantum capacitance (QC), and adsorption energies of alkali metals (Li, Na, K) on the NiO [001] and [111] planes. The study reveals that a decrease in the lattice parameter leads to a reduction in the band gap (from 2.28 to 2.19 eV). The adsorption energies demonstrate a strong surface reactivity, with Li showing the highest affinity for the NiO [001] surface and Na exhibiting the highest adsorption energy on the more reactive NiO [111] surface. The QC analysis demonstrated notable enhancements following alkali metal adsorption, with Li on the NiO [001] surface exhibiting a QC of 38.9 μF/cm2 at a = 4.23 Å, whereas Na on the NiO [111] surface achieved a QC of 32.7 μF/cm2 at a = 4.187 Å. These findings underscore the critical role of lattice strain and surface orientation in modulating the electrochemical performance of NiO, with potential applications in catalysis, energy storage, and electronic devices.","PeriodicalId":100403,"journal":{"name":"Electron","volume":"3 2","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/elt2.70006","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144219957","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}

However, it is still challenging to synthesize highly crystalline g-C3N4, favoring the separation of photogenerated electron–hole pairs and promoting improved photocatalytic activity. Herein, we report a novel approach to achieve highly crystalline g-C3N4 by simply pressing sodium chloride and carbon nitride into a pellet followed by heat treatment, which is different from conventional molten salt methods. The resulting g-C3N4 has an optimum band structure that benefits enhanced light absorption and charge separation efficiency. The intimate contact between sodium chloride and carbon nitride in the pressed pellet facilitates the diffusion of sodium ions and increases the material's resistance to high annealing temperatures, leading to improved crystallinity. The photocurrent response of this highly crystalline material under visible light irradiation is approximately four times higher than that of its bulk counterpart, resulting in a hydrogen production rate of up to 650 μmol g−1 h−1 (10% TEOA). This work paves a new path in designing novel carbon nitrides with enhanced photoelectrochemical and photocatalytic performance.","PeriodicalId":100403,"journal":{"name":"Electron","volume":"3 2","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-03-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/elt2.70000","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144220173","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}

These emerging applications impose stringent requirements on flexible sensors, necessitating not only their ability to withstand dynamic strains and conform to irregular surfaces but also to ensure long-term stable monitoring. To meet these demands, one-dimensional nanowires, with high aspect ratios, large surface-to-volume ratios, and programmable geometric engineering, are widely regarded as ideal candidates for constructing high-performance flexible sensors. Various innovative assembly techniques have enabled the effective integration of these nanowires with flexible substrates. More excitingly, semiconductor nanowires, prepared through low-cost and efficient catalytic growth methods, have been successfully employed in the fabrication of highly flexible and stretchable nanoprobes for intracellular sensing. Additionally, nanowire arrays can be deployed on the cerebral cortex to record and analyze neural activity, opening new avenues for the treatment of neurological disorders. This review systematically examines recent advancements in nanowire-based flexible sensing technologies applied to wearable electronics, BCIs, and electronic skins, highlighting key design principles, operational mechanisms, and technological milestones achieved through growth, assembly, and transfer processes. These developments collectively advance high-performance health monitoring, deepen our understanding of neural activities, and facilitate the creation of novel, flexible, and stretchable electronic skins. Finally, we also present a summary and perspectives on the current challenges and future opportunities for nanowire-based flexible sensors.","PeriodicalId":100403,"journal":{"name":"Electron","volume":"3 2","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-02-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/elt2.77","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144219956","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}
