The efficiency of photocatalytic NO removal is often constrained by catalyst lifespan and secondary contamination from reaction products. Therefore, in this study, g-C3N4 (CN) was incorporated into a photothermal reaction system for synergistic NO removal via photothermal effects. It was observed that increasing the temperature led to a 19% enhancement in CN's photocatalytic removal efficiency, with a selectivity of 96.8% towards NO2 generation. Additionally, the catalyst's lifespan increased by 2.85 times, while the quantum yield rose from 1.54% to 2.22%. This study also provides novel insights into the mechanism of photothermal synergy: (1) high temperatures facilitate more efficient capture of O2 by hot electrons, promoting ˙O2− generation; (2) the catalyst structure is regulated by temperature elevation, as hot electrons promote greater n → π* transfer on CN, which is favorable for electron–hole separation and transfer. As a result, CN-based photothermal collaborative catalysis shows promising prospects for NO removal. [ABSTRACT FROM AUTHOR]

Heterogeneous information networks (HINs) contain a rich network structure and semantic information, which makes them commonly used in recommendation systems. However, most of the existing HIN-based recommendation systems rely on meta-paths for information extraction, lack meta-path information supplements, and rarely learn complex structure information in heterogeneous graphs. To address these issues, we develop a novel recommendation algorithm that integrates the attention mechanism, meta-paths, and neighbor node information (AMNRec). In the heterogeneous information network, the missing information of the meta-path is supplemented by extracting the information of users and items' neighbor nodes. The rich interactions between nodes are captured through convolution, and the embedded representation of nodes and meta-paths is obtained through the attention mechanism. TOP-N recommendation is completed by combining users, items, neighbor nodes, and meta-paths. Experiments on three public datasets show that AMNRec not only has the best recommendation performance but also has good interpretability of the recommendation results compared with the six recommendation benchmark algorithms.

The detection of norfloxacin (NOR) is crucial because the overdoes and accumulation may result in residues in environment in animal-derived foods, which can destroy ecology and cause disease for people. A molecularly imprinted electrochemical sensor based on g-C3N4/Cu-MOF was constructed for the selective detection of norfloxacin in this paper. The g-C3N4/Cu-MOF was synthesized by melamine pyrolysis and solvothermal method followed by ultrasonic mixing. After drop casting g-C3N4/Cu-MOF on glassy carbon electrode, the molecularly imprinted film was synthesized by electropolymerization. The composite was analyzed by powder X-ray diffractometer, field emission scanning and transmission electron microscope, and Fourier transform infrared spectroscopy. The electrochemical properties of the sensor were characterized by cyclic voltammetry, electrochemical impedance spectroscopy, and pulse voltammetry. The results show that the composite of g-C3N4/Cu-MOF efficiently decreased the charge transfer resistance of electrode and improved the electron transfer kinetic between analyte and electrode with the improved current response and increased active area. After optimizing conditions of the ratio of functional monomers to template molecules, the number of polymerization cycles, accumulation time, electrolyte pH, and the sensor exhibits excellent response toward NOR with the linearity range of 0.02–0.1 μmol/L and 1–120 μmol/L and the limit of detection of 6.67 nmol/L. Moreover, it shows good selectivity, anti-interference, and reproducibility properties. In the real sample detection of pharmaceutical formulations, serum and milk, the sensor shows an acceptable recovery rate and standard deviation. [ABSTRACT FROM AUTHOR]

We propose a single-pixel imaging (SPI) method to achieve a higher-resolution image via the Hadamard transform matrix. Unlike traditional SPI schemes, this new method recovers images by correlating single-pixel signals with synchronized transformed patterns of Hadamard bases that are actually projected onto the digital micromirror device. Each transform pattern is obtained through the inverse Fourier transform of the pattern acquired by Gaussian filtering of each Hadamard basis in the frequency domain. The proposed scheme is based on a typical SPI experimental setup and does not add any hardware complexity, enabling the transformation of Hadamard matrices and image reconstruction through data processing alone. Therefore, this approach could be considered as an alternative option for achieving fast SPI in a diffraction-limited imaging system, without the need for additional hardware. [ABSTRACT FROM AUTHOR]

Dopamine (DA) is known as a crucial neurotransmitter synthesized and secreted by dopaminergic neurons and plays a role in regulating human emotions and behaviors. The determination of DA content is of great significance in clinical application and physiological function research. An electroanalytical sensor based on the ternary semiconductor material copper indium selenide (CuInSe2) coated carbon spheres functionalized glassy carbon electrode (CuInSe2@CS/GCE) towards the non‐invasive determination of DA was constructed in this study. The performances of the sensor were characterized using cyclic voltammetry, impedance method, and differential pulse voltammetry. The results show that wrinkled CuInSe2 completely coated on CS. The sensor exhibits good electrochemical kinetics and response signal towards DA, which results from the good electrochemical activity and excellent electroconductibility of transition metal centers of the composite. The determination limit of the proposed sensor towards DA is 0.59 μM (S/N=3), and the linear measuring range is between 1–800 μM. In addition, the sensor exhibits desirable long‐term robustness, reproducibility, repetitiveness, and interference immunity. In the non‐invasive determination towards real samples of human urine and sweat, the sensor provides good recovery rate and small determination deviation. [ABSTRACT FROM AUTHOR]

The article focuses on a case of Fontan circulatory failure due to conduit angulation stenosis in a 32-year-old woman who had undergone Fontan surgery 27 years prior. Topics include the diagnosis and imaging techniques used to identify conduit angulation and stenosis, the surgical intervention involving conduit replacement with a FEP-Ringed Gore-Tex graft, and the post-operative improvements in the patient's oxygen saturation and cardiac function.
