To address this issue, we propose creating N vacancies within the layers and bridging K single-atoms between the C3N4 layers through the self-assembly of potassium citrate and melamine–urea monomers. The introduction of N vacancies disrupts the symmetry of C3N4, promoting electron transfer along the delocalized π-conjugated network, while the presence of K atoms provides channels for electron transfer between the layers by forming N–K–N bridges, thereby leading to significant enhancement in the separation and transfer of e–/h+ pairs across spatial dimension. As expected, the co-modified C3N4, with N vacancies and K single-atoms (designated as CN-K-VN), exhibits excellent photocatalytic performance, with reaction rate constant of 9.69×10–2 min–1 (7.39×10–2 min–1 in real water environment) for tetracycline, achieving 80% degradation of tetracycline within 20 minutes. The reaction mechanism, as well as the toxicity of the degradation intermediates, is deeply discussed. This study provides a strategy to enhance the spatial separation of electrons for photocatalyst, highlighting its significance role in photocatalysis.","PeriodicalId":16173,"journal":{"name":"Journal of Materiomics","volume":"76 1","pages":""},"PeriodicalIF":9.4,"publicationDate":"2024-11-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142665426","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Nonetheless, the photocatalytic performance is limited by sluggish photogenerated carrier separation and limited redox potentials. Herein, an S-scheme heterojunction was constructed by assembling the TiO2 nanoparticles and a Schiff-base COF together. The formed S-scheme TiO2/COF heterojunction can efficiently produce H2O2 and degrade Rhodamine B (RhB) synchronously. The S-scheme charge transfer mechanism in TiO2/COF composite is well unveiled by in situ irradiated X-ray photoelectron spectroscopy and DFT calculation. The femtosecond transient absorption spectra reveal the superior charge migration at interface between TiO2 and COF. The designed TiO2/COF composite shows drastically enhanced H2O2 yield of 1326 μmol·g–1·h–1 in RhB solution, and the AQY value of 4.11% under 420 nm monochromatic light irradiation is achieved. Meanwhile, 100% of RhB degraded under light irradiation for 40 min with TiO2/TD COF as photocatalyst.

This study employed an artificial intelligence-driven materials design framework for identifying dopants that impart antiferroelectric properties to HfO2 materials. This strategy integrates density functional theory (DFT) with machine learning (ML) techniques to swiftly screen HfO2 materials exhibiting stable antiferroelectric properties based on the critical electric field. This approach aims to overcome the high cost and lengthy cycles associated with traditional trial-and-error and experimental methods. Among 30 undeveloped dopants, four candidate dopants demonstrating stable antiferroelectric properties were identified. Subsequent DFT analysis highlighted the Ga dopant, which displayed favorable characteristics such as a small volume change, minimal lattice deformation, and a low critical electric field after incorporation into hafnium oxide. These findings suggest the potential for stable antiferroelectric performance. Essentially, we established a correlation between the physical characteristics of hafnium oxide dopants and their antiferroelectric performance. The approach facilitates large-scale ML predictions, rendering it applicable to a broad spectrum of functional material designs.","PeriodicalId":16173,"journal":{"name":"Journal of Materiomics","volume":"6 1","pages":""},"PeriodicalIF":9.4,"publicationDate":"2024-11-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142637787","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, we show that a non-destructible permanent poled state can be realized in relaxor-PbTiO3 single crystals by forming a 0–3 composite in the presence of charged mobile point defects. We demonstrate this on solid-state grown 0.71 Pb(Mg1/3Nb2/3)O3-0.29PbTiO3 single crystals doped with Mn (Mn-PMNT) as a donor with well-aligned and dispersed boron-rich MgO-based inclusions (MBIs).

The piezoelectric coefficient and dielectric permittivity of self-poled Mn-PMNTMBI crystals were as large as 90% of that achieved by a direct-current poling treatment at room temperature, and such poled state was reproducible against repeated thermal cycles. We expect that the poling-free high-performance piezoelectric relaxor-PbTiO3 single crystals offer an avenue for piezoelectric-based devices by removing the working temperature limit as one of the inherent fundamental limitations.</div></div>","PeriodicalId":16173,"journal":{"name":"Journal of Materiomics","volume":"11 3","pages":"Article 100887"},"PeriodicalIF":8.4,"publicationDate":"2024-05-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142658233","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This device exhibits excellent reliability, maintaining a stable output over 105 electrical cycles. Additionally, a “back-to-back” coupled MFCA has been developed to regulate bidirectional displacement, making it suitable for various practical applications, including active vibration control.
