In this article, Bi-based metal–organic framework-supported silicotungstic acid (STA) was synthesized by a simple hydrothermal method and used as a precursor for the preparation of the Bi-based MOF-derived catalyst (STA@C-Bi-BDC). Using a combination of FTIR, XRD, SEM-EDS, N2 adsorption–desorption, TG, UV-Vis DRS, and XPS techniques, the successful immobilization of STA groups on Bi-MOF-derived C-Bi-BDC was assessed. Furthermore, the photocatalytic performance of the as-prepared catalysts was investigated in the degradation of the RhB dye process under visible light. Within 120 min of visible light exposure, the high degradation rate of RhB (92.7%) by STA@C-Bi-BDC system was achieved, which was a lot larger than the STA (39.4%), C-Bi-BDC (59.2%), and STA@Bi-BDC (74.0%) system, and cyclic experiments exhibit that the STA@C-Bi-BDC is a relatively stable photocatalyst. More importantly, the catalyst shows high applicability for the degradation of other dyes. This study reveals a comprehensive strategy for the design of efficient Bi-based MOF-derived photocatalyst for organic dye-based wastewater treatment.

For nearly a century, the excessive discharge of organic contaminants has gradually polluted water and endangered people's health, and photocatalysis has been prominently employed to remove persistent recalcitrant organic. Here, MIL‐101(Cr) was firstly employed to introduce thin‐layered Bi2O2CO3 for the formation of Bi2O2CO3/MIL‐101(Cr) nanosheet composite, by a simple and low‐temperature in‐situ growth approach. The phase, morphology, optical, and surface characteristics of the fabricated composite were characterized through XRD, FTIR, SEM‐EDS, N2 adsorption–desorption, UV–Vis DRS, PL, TG, and XPS techniques, and the ability in the photocatalytic breakdown of rhodamine B (RhB) molecule under visible light was also studied. The results of characterization analysis and optical analysis exhibited that Bi2O2CO3/MIL‐101(Cr) has large pore size, good visible light response‐ability, and the heterojunction created by intercalating Bi2O2CO3 on MIL‐101(Cr). Photocatalytic studies revealed that Bi2O2CO3/MIL‐101(Cr) had superior RhB degradation activity than pure MIL‐101(Cr) and Bi2O2CO3, which achieved 97.1% with visible light irradiation for 20 mg/l RhB. Meanwhile, the Bi2O2CO3/MIL‐101(Cr) composite displayed good recyclability after three cycles as revealed by XRD and FTIR analysis proving their excellent stability. This study provides feasible insight into developing novel and efficient MIL‐101‐based heterojunction catalysts for environmental remediation in the future. [ABSTRACT FROM AUTHOR]

Adenoid hypertrophy can lead to adenoidal mouth breathing, which can result in “adenoid face” and, in severe cases, can even lead to respiratory tract obstruction. The Fujioka ratio method, which calculates the ratio of adenoid (A) to nasopharyngeal (N) space in an adenoidal-cephalogram (A/N), is a well-recognized and effective technique for detecting adenoid hypertrophy. However, this process is time-consuming and relies on personal experience, so a fully automated and standardized method needs to be designed. Most of the current deep learning-based methods for automatic diagnosis of adenoids are CNN-based methods, which are more sensitive to features similar to adenoids in lateral views and can affect the final localization results. In this study, we designed a local attention-based method for automatic diagnosis of adenoids, which takes AdeBlock as the basic module, fuses the spatial and channel information of adenoids through two-branch local attention computation, and combines the downsampling method without losing spatial information. Our method achieved mean squared error (MSE) 0.0023, mean radial error (MRE) 1.91, and SD (standard deviation) 7.64 on the three hospital datasets, outperforming other comparative methods.

This study explores the innovative application of iron filings solid waste, a byproduct from mechanical workshops, as a heterogeneous catalyst in the production of biodiesel from waste cooking oil. Focusing on sustainability and waste valorization, the research presents a dual-benefit approach: addressing the environmental issue of solid waste disposal while contributing to the renewable energy sector. Particle size distribution analysis, X-ray diffraction (XRD), scanning electron microscopy (SEM), X-ray fluorescence (XRF), Thermal analysis (TG-DTA), and FTIR analysis were used to characterize the iron filings. The response surface methodology (RSM) was used to guide a series of experiments that were conducted to identify the optimum transesterification settings. Important factors that greatly affect the production of biodiesel are identified by the study, including catalyst loading, reaction time, methanol-to-oil ratio, reaction temperature, and stirring rate. The catalyst proved to be successful as evidenced by the 96.4% biodiesel conversion efficiency attained under ideal conditions. The iron filings catalyst's reusability was evaluated, demonstrating its potential for numerous applications without noticeably decreasing activity. This work offers a road towards more environmentally friendly and sustainable chemical processes in energy production by making a strong argument for using industrial solid waste as a catalyst in the biodiesel manufacturing process.

Development of an energy‐efficient and economical route is necessary for society to synthesize green biofuels. Herein, cobalt‐doped tungstophosphoric acid (Co‐HPW) is in‐situ impregnated in the Zr‐based metal–organic framework (MOF‐801) forming composite of Co‐HPW/MOF‐801. The chemical composition, morphology, and acidic sites of the Co‐HPW/MOF‐801 composite were analyzed through x‐ray diffractometer (XRD), Fourier transform infrared (FTIR), scanning electron microscope (SEM), energy‐dispersive x‐ray spectroscopy (EDS), thermogravimetric analysis (TG), N2 physisorption, ammonia temperature‐programmed desorption (NH3‐TPD), pyridine‐adsorbed infrared spectra (Py‐FTIR), and x‐ray photoelectron spectroscopy (XPS). The catalytic performance of the as‐synthesized catalyst was explored to catalyze esterification of lauric acid (LA) with methanol. The outcomes revealed that the Co‐HPW/MOF‐801 nanocatalyst achieved a high conversion of 86.3% under the optimized reaction condition (catalyst amount of 0.15 g, temperature of 100°C, time of 4 h, and methanol/LA molar ratio of 20:1). The excellent catalytical performance is mainly due to the large BET surface area, exposure of more active centers from available pore structure, and simultaneous possession of high Lewis and Brønsted acidity. Furthermore, the kinetic study revealed that the reaction process was kinetically controlled and the activation energy was found to be 42.1 kJ/mol. The results suggest that the synthesized Co‐HPW/MOF‐801 nanocatalyst is an environmental greenness, low cost, and suitable for easy scale‐up for the production of biofuels. [ABSTRACT FROM AUTHOR]

This study presents a novel method for synthesizing 1,4-disubstituted 1,2,3-triazole derivatives through a one-pot, multi-component addition reaction using flower-like Cu2O microbeads as a catalyst. The flower-like Cu2O microbeads were synthesized using an aqueous extract of Artimisia Campestris L. This extract demonstrated the capability to reduce and stabilize Cu2O particles during their initial formation, resulting in the formation of a porous flower-like morphology. These Cu2O microbeads exhibit distinctive features, including a cubic close-packed (ccp) crystal structure with an average crystallite size of 22.8 nm, bandgap energy of 2.7 eV and a particle size of 6 μm. Their catalytic activity in synthesizing 1,4-disubstituted 1,2,3-triazole derivatives was investigated through systematic exploration of key parameters such as catalyst quantity (1, 5,10,15, 20, and 30 mg/mL), solvent type (dimethylformamide/H2O, ethanol/H2O, dichloromethane/H2O, chloroform, acetone, and dimethyl sulfoxide), and catalyst reusability (four cycles). The Cu2O microbeads significantly increased the product yield from 20% to 85.3%. The green synthesis and outstanding catalytic attributes make these flower-like Cu2O microbeads promising, efficient, and recyclable catalysts for sustainable and effective chemical transformations.

Background and Objective: This study aimed to investigate the factors affecting the development of low anterior resection syndrome (LARS) following anus-preserving surgery for rectal cancer, and to assess the impact of a rapid rehabilitation surgical nursing intervention on patient outcomes. LARS is a significant issue for patients undergoing these surgeries, as it can severely impact quality of life. Understanding the risk factors for LARS is crucial to develop targeted interventions to improve post-operative recovery., Methods: The study retrospectively analyzed the clinical data of 78 rectal cancer patients who underwent anus-preserving radical resection. The occurrence of LARS was assessed using the LARS score scale. Univariate and multivariate logistic regression analyses were performed to identify factors that may affect the development of LARS, including distance of the anastomosis from the anal verge, preoperative chemoradiotherapy, and postoperative anastomotic leakage. Additionally, the study compared outcomes between two patient groups - a control group receiving routine surgical nursing care, and an experimental group receiving a rapid rehabilitation surgical nursing intervention. This intervention included preoperative patient education, optimized anesthesia and surgical techniques, and intensive postoperative rehabilitation. Key outcomes measured included time to first flatus, time to first defecation, duration of pain-free days, length of hospital stay, and total hospitalization costs., Results: The univariate regression analysis showed that the distance from the anastomosis to the anal verge (OR=4.364, P < .001, 95% CI 2.732-7.257), preoperative chemoradiotherapy (OR=9.135, P = .004, 95% CI 1.963-40.316), and postoperative anastomotic leakage (OR=2.636, P < .001, 95% CI 1.641-4.245) were significant risk factors for the development of LARS. The multivariate logistic regression analysis confirmed that a shorter distance between the anastomosis and anal margin, preoperative radiotherapy, and postoperative anastomotic leakage were independent predictors of LARS (all P < .05). Comparison of the two patient groups showed that the rapid rehabilitation surgical nursing intervention had a significant positive impact. Patients in the experimental group (group E) had a significantly shorter time to first exhaust (62.19±7.43 minutes vs. 96.18±10.62 minutes in group C, P < .001) and first defecation (85.26±8.41 minutes vs. 130.26±12.38 minutes in group C, P < .001). Group E also experienced a longer duration of 0 pain score days (3.57±0.72 days vs. 5.42±1.05 days in group C, P < .001), shorter hospital stays (10.15±2.05 days vs. 15.33±1.23 days in group C, P < .001), and lower total hospitalization costs (31.80±3.70 thousand Yuan vs. 42.80±5.60 thousand Yuan in group C, P < .001)., Conclusion: This study identified the distance between the anastomosis and anal margin, preoperative radiotherapy, and postoperative anastomotic leakage as independent risk factors for the development of LARS in patients undergoing anus-preserving surgery for rectal cancer. These findings can inform preoperative risk assessment and guide surgical planning to mitigate the risk of LARS. Patients identified as high-risk may benefit from more intensive preoperative counseling and targeted nursing interventions to optimize postoperative bowel function. Notably, the rapid rehabilitation surgical nursing intervention demonstrated significant benefits in accelerating patient recovery, reducing complications, and lowering overall healthcare utilization. This comprehensive nursing approach, encompassing preoperative education, optimized perioperative management, and intensive postoperative rehabilitation, offers a promising model to improve standards of care for rectal cancer patients undergoing anus-preserving surgeries. Widespread adoption of such targeted nursing interventions has the potential to enhance patient outcomes, quality of life, and healthcare resource efficiency in this patient population.
