Constructing S-scheme heterojunctions is an effective method for facilitating charge transfer, but the huge interfacial charge transfer barrier poses a challenge to advance the efficiency of photocatalytic OWS. Here, a low-interfacial barrier Ce-S bond-enhanced Mo-doped ZnIn2S4/oxygen-deficient CeO2 (Mo-ZIS/OV-CeO2) S-scheme heterojunction photocatalyst was designed via a doping-defect coupling strategy. The abundant unsaturated S atoms generated by doping Mo atoms in ZnIn2S4 combine with the unpaired electrons on the Ce atom in OV-CeO2, forming the interfacial Ce-S bonds, which induce a 43% decrease in carrier transport activation energy and a 2.1-fold increase in build-in electric field intensity compared to ZIS/OV-CeO2. Reduced carrier transport activation energy and increased built-in electric field intensity provide a strong driving force for charge separation following the S-scheme pathway. Benefiting from the interfacial Ce-S bonds and the S-scheme transfer path, Mo-ZIS/OV-CeO2 exhibits H2 and O2 evolution rates of 512.7 and 256.3 μmol g−1 h−1, respectively, along with a solar-to-hydrogen efficiency of 0.14%. This study proposes an innovative insight into developing and constructing S-scheme heterojunction photocatalysts with efficient charge migration interfaces.","PeriodicalId":100671,"journal":{"name":"InfoScience","volume":"2 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-03-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/inc2.12028","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143865590","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}

(2) Due to large mobility difference of typical ETLs and HTLs, carriers-unbalanced injection leads to severe performance degradation. Herein, we propose a potential strategy to address such challenges using MAPbCl3 and CsSnCl3 as carrier transport layers with mobility 3 orders larger than typical ETLs and HTLs. Via transfer matrix method calculations, we find that the reflectance of DBRs composed of MAPbCl3 (130.5 nm)/CsSnCl3 (108 nm) is larger than 91% with 10 pairs of DBRs. Furthermore, the proposed EPVCSEL device simulation shows that MHP-EPVCSEL has the potential to achieve room temperature continuous wave lasing with a threshold current density of ∼69 A cm−2 and output optical power ∼10−4 W.

The ε-Ga2O3 epilayer is grown on the c-sapphire with a low temperature nucleation layer, which presents a crystal orientation relationship with the c-sapphire (ε-Ga2O3 <010> // c-sapphire <1–100> and ε-Ga2O3 <001> // c-sapphire <0001>).

Under the UV pulse excitation, the photonic device exhibits primary synaptic functions including excitatory postsynaptic current, short term memory, pair pulse facilitation, long term memory, and STM-to-LTM conversion. In addition, stronger and repeated stimuli can naturally contribute to the higher learning capability, thus prolonging the memory time.","PeriodicalId":100671,"journal":{"name":"InfoScience","volume":"2 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-10-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/inc2.12022","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143866006","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, the current performance of photocatalysis is largely impeded by the fast recombination of photogenerated charge carriers and insufficient light absorption. Among various materials, bismuth-based photocatalysts have stood out as excellent candidates for efficient photocatalysis due to their unique controllable crystal structures and relatively narrow band gap. These features endow the selective exposure of active facets (facet engineering) and wide light absorption range, resulting in tunable photocatalytic activity, selectivity, and stability. Therefore, it is of great potential to use facet-engineered bismuth-based photocatalysts for efficient energy applications (e.g., water splitting, CO2 reduction, N2 fixation, and H2O2 production) to achieve sustainable development. Herein, the introduction provides the overview of this research, while the synthesis, modification strategy, and the latest progress of facet-engineered bismuth-based photocatalysts in energy application were summarized and highlighted in this review paper.

Efficient Cherenkov radiation over a wide range of momenta is highly demanded for many applications but still remains a challenging task. To this end, we explored the interaction between swift electrons and twisted hyperbolic Van der Waals crystals and observed enhanced Cherenkov radiation at the flatband resonance frequency. We show that, at the photonic magic angle of the twisted crystals, the electron momentum, once matching with that of the flatband photon, gives rise to a maximum energy loss (corresponding to the surface phonon generation), one-order of magnitude higher than that in conventional hyperbolic materials. Such a significant enhancement is attributed to the excitation of flatband surface phonon polaritons over a broad momentum range. Our findings provide a feasible route for highly directional free-electron radiation and radiation shaping.","PeriodicalId":100671,"journal":{"name":"InfoScience","volume":"2 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/inc2.12024","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143865909","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}

Subsequently, we summarize the development of AOR electrocatalysts, including noble-metal-based catalysts, non-noble-metal-based catalysts, and homogeneous catalysts.

At present, lithium (Li) metal anode is regarded as one of the most promising anode materials, but it still faces major problems in terms of capacity fading and safe and stable long-term cycle. The reason for the continuous fading of Li anode capacity is mainly due to the loss of active Li source, and the loss of Li source is mainly due to the continuous generation of dead Li. At the same time, the unstable interface and dendrite growth of Li anodes during the Li plating/delithiation process eventually lead to battery safety issues. In fact, recent studies have shown that the disordered expansion of dendrites is the main reason for the infinite generation of dead Li. Therefore, here we take different detection techniques as clues, review the exploration process of qualitative and quantitative research on the source and mechanism of Li capacity loss, and summarize the strategies to reduce dead Li generation and capacity fading by inhibiting dendrite formation. In particular, we give suggestions on the development of advanced testing methods on how to further study the problem of dead Li, and also give relevant strategy suggestions on how to completely solve the problem of capacity loss in the future, with the main goal of suppressing dendrites.","PeriodicalId":100671,"journal":{"name":"InfoScience","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-08-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/inc2.12006","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142862285","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}
