Abstract Solar‐driven high‐efficiency and direct conversion of methane into high‐value‐added liquid oxygenates against overoxidation remains a great challenge. Herein, facile and mass fabrication of low‐cost tungsten single‐atom photocatalysts is achieved by directly calcining urea and sodium tungstate under atmosphere (W‐SA‐PCN‐ m , urea amount m = 7.5, 15, 30, and 150 g). The single‐atom photocatalysts can manage H 2 O 2 in situ generation and decomposition into ·OH, thus achieving highly efficient CH 4 photooxidation in water vapor under mild conditions. Systematic investigations demonstrate that integration of multifunctions of methane activation, H 2 O 2 generation, and decomposition into one photocatalyst can dramatically promote methane conversion to C1 oxygenates with a yield as high as 4956 µmol g cat −1 , superior to that of the most reported non‐precious photocatalysts. Liquid–solid phase transition can induce the products to facilely switch in from HCOOH to CH 3 OH by pulling the catalyst above water with CH 3 OH/HCOOH ratio from 10% (in H 2 O) to 80% (above H 2 O).

In today’s digital age, people make use of digital media platforms to interact and ‘influence’ each other on social media (Brown and Hayes, 2007). Social media influencers (SMI) are such users who have attained a celebrity-like status and secured a considerable network of followers by developing engaging content based on expertise in a specific domain, and who directly influence the behavior of their followers (Hearn and Schonhoff, 2016; De Veriman et al., 2017; Ge and Gretzel, 2018). VI, also termed as a virtual celebrity, digital personality, CGI influencer (Mrad et al., 2022), or AI influencer (Thomas and Fowler, 2021) refer to fictional personalities created through computer imagery (Miao et al., 2022). They possess human- like characteristics (Burden and Savin-Baden, 2019), physical features and personality (Moustakas et al., 2020), and indulge in online activity (Hudders et al., 2021; Moustakas et al., 2020). VI exhibit anthropomorphism (Moustakas et al., 2020), ranging from anime-like to almost human-like appearance (Kim et al., 2023), and akin to human influencers, can be effective as they can look and behave like human influencers (Sands et al., 2020). In the case of human SMIs, scholars have adopted the opinion leadership framework to analyze the persuasive traits of an endorser. Katz and Lazersfeld (1955) have highlighted the significant role played by the media spokesperson in persuading audience into use sponsors’ product or services, which they termed as the ‘opinion leader’. Thus, trust in an endorser is of utmost importance. Consumer segments are heterogeneous and factors which contribute or detract viewer trust in VI can also differ. VI phenomena are at the introductory stage in emerging economies like India, and we aim to gain insight on viewers perception of VI as new endorser.
BACKGROUND: Accurate locoregional staging is critical in the management of T1 rectal cancer and guides organ-preserving strategies. Despite guideline recommendations, the real-world performance of magnetic resonance imaging (MRI) and endoscopic ultrasound (EUS) remains unclear. This study aims to evaluate the use and accuracy of locoregional staging in T1 rectal cancer. METHODS: Retrospective analysis was performed from a nationwide multicentre T1 colorectal cancer cohort (EpiT1 Consortium) between 2007 and 2018 with a 5-year follow-up. Locoregional staging methods included MRI and EUS. Multivariable logistic regression identified factors associated with locoregional imaging. The accuracy of each technique and their combination for T and N staging was assessed. RESULTS: Among 3161 patients with T1 colorectal cancer, 681 had rectal cancer, of which 424 (62.3%) underwent locoregional staging: 234 (55.2%) with MRI only, 131 (30.9%) with both MRI and EUS, and 59 (13.9%) with EUS only. Factors associated with imaging (MRI and EUS) included management at a referral centre (odds ratio 2.9, 95% confidence interval 1.5 to 5.7), tumour location in the low/middle rectum (odds ratio 3.2, 1.8 to 5.7), suspicion of invasive carcinoma at colonoscopy (odds ratio 2.4, 1.3 to 4.5), and high-risk histological features (odds ratio 3.7, 1.8 to 7.4). MRI accurately staged T in 28.3%, whereas EUS achieved an accuracy of 59% for T staging. Combining modalities overstaged 67.1% of tumours for T staging. N staging was detected with ≤ 16% sensitivity across all strategies; in the surgical group (MRI and/or EUS), overall accuracy was 78%. CONCLUSION: Locoregional staging varied widely and was influenced by non-tumour-related factors. MRI and EUS showed modest accuracy, overstaging T, and low sensitivity for N. These findings highlight the need to improve pretreatment evaluation of T1 rectal cancer.
Abstract For heterogeneous catalysts, the active sites exposed on the surface have been investigated intensively, yet the effect of the subsurface‐underlying atoms is much less scrutinized. Here, a surface‐engineering strategy to dope Ru into the subsurface/surface of Co matrix is reported, which alters the electronic structure and lattice strain of the catalyst surface. Using hydrogen evolution (HER) as a model reaction, it is found that the subsurface doping Ru can optimize the hydrogen adsorption energy and improve the catalytic performance, with overpotentials of 28 and 45 mV at 10 mA cm −2 in alkaline and acidic media, respectively, and in particular, 28 mV in neutral electrolyte. The experimental results and theoretical calculations indicate that the subsurface/surface doping Ru improves the HER efficiency in terms of both thermodynamics and kinetics. The approach here stands as an effective strategy for catalyst design via subsurface engineering at the atomic level.
Abstract Although much effort has been devoted to improving photoelectrochemical water splitting of hematite (α-Fe 2 O 3 ) due to its high theoretical solar-to-hydrogen conversion efficiency of 15.5%, the low applied bias photon-to-current efficiency remains a huge challenge for practical applications. Herein, we introduce single platinum atom sites coordination with oxygen atom (Pt-O/Pt-O-Fe) sites into single crystalline α-Fe 2 O 3 nanoflakes photoanodes (SAs Pt:Fe 2 O 3 -Ov). The single-atom Pt doping of α-Fe 2 O 3 can induce few electron trapping sites, enhance carrier separation capability, and boost charge transfer lifetime in the bulk structure as well as improve charge carrier injection efficiency at the semiconductor/electrolyte interface. Further introduction of surface oxygen vacancies can suppress charge carrier recombination and promote surface reaction kinetics, especially at low potential. Accordingly, the optimum SAs Pt:Fe 2 O 3 -Ov photoanode exhibits the photoelectrochemical performance of 3.65 and 5.30 mA cm −2 at 1.23 and 1.5 V RHE , respectively, with an applied bias photon-to-current efficiency of 0.68% for the hematite-based photoanodes. This study opens an avenue for designing highly efficient atomic-level engineering on single crystalline semiconductors for feasible photoelectrochemical applications.
Shape-memory polymers (SMP) are a class of materials that are better known as smart materials. The smartness of the SMP comes from their tunability properties allowing them to tweak into various shapes and orientations as per the desired applications. Many animals can change the stiffness of their skin, adopt the colors from the environment, change their appearance according to needs and in case of approaching danger, etc. Inspired by these above natural phenomena, many smart materials have been developed by researchers over the last decade and SMP is one of them. SMP polymers can easily be manipulated to the desired shape by changing their physical and chemical parameters such as temperature, light, ultrasound, chemical cross-linkage, crystallization, etc. SMP is a suitable candidate for designing novel metamaterials or programmable metamaterials in which the temporary shape can be retained and also imposed and controlled through programming such that the initial shape of the material can be recovered by an application of an external stimulus. The best characteristic of these polymers is the retain-ability of original or temporary shape in different stimuli fields prompting this material to have a memory effect for shape retainability. Due to such exceptional properties of the SMP, these smart materials find wide applications in Aerospace, Biomedical micro-devices, Robotics, Acoustics, Electronics, Textiles, Bionics engineering, and many other contemporary fields.This chapter discusses some fundamentals related to the fabrication strategies, emerging application aspects, and memory retention/ programming aspects of the shape memory polymers. The current state of the art and future directions has also been outlined to provide a roadmap for smart memory polymers-based technologies.
