    Abstract: Composting is a highly effective method for managing the growing quantity of agricultural waste, promoting nutrient recycling, and advancing sustainable agriculture. However, the significant amounts of volatile inorganic compounds (VICs) and volatile organic compounds (VOCs) generated during the composting process cannot be ignored due to their serious ecological environmental hazards and detrimental impact on human health. The types and pathways of VICs and VOCs produced during the composting process remain not well understood. Methods In this study, we investigated the VOCs produced during chicken manure and straw composting using gas chromatography–mass spectrometry (GC/MS). We performed qualitative and quantitative analyses of VOCs in composting emissions gases and their correlation with odor. Results Our results showed that 44 VOCs were detected during composting, including 4 oxidation-containing compounds, 2 sulfur-containing organics, 5 alkanes, 19 halogenated compounds, and 14 aromatic compounds. Aromatic compounds were found to be the main component of VOCs, accounting for 59.14% of the total content. The highest VOC content was found in the pre-composting period, and the highest emitting VOC was p-Isopropyl Toluene, which reached 7870.50 μg/m 3 . We identified eight substances that were highly correlated with odor concentration ( p   & lt; 0.01) and are the main odor-causing substances that need to be monitored and controlled. Discussion Our study provides important insights into the transformation of volatile gases during the composting process. It highlights the need for proper management practices to control VOCs emissions and reduce their environmental impact.

    Abstract: Investigating the wettability of the tool surface made of cemented carbide is of great significance to improve its working life and quality. The micropit array was processed on the surface of cemented carbide YT15 by a 1064 nm femtosecond pulse laser. Then, the optical microscope, the optical profilometer, and the contact angle measuring instrument were applied to measure the surface morphology and the surface contact angle of micropits. The influence of different laser parameters on surface morphology and the surface contact angle was studied. The geometric morphology model of the micropit was established. The influence of the morphology of micropits on the surface contact angle is analyzed based on the Wenzel theory. The results show that the radius and depth of micropits have a positive correlation with the average laser power and scanning times. As the spacing increases, the surface roughness factor and the surface contact angle decrease. There is a strong correlation between the characterization parameters kurtosis, skewness, and surface wettability in a 3D height parameter system. The smaller the kurtosis, the greater the skewness and the better the surface hydrophilicity.

    Abstract: The gradient wettability surface is processed on the surface of Si 3 N 4 ceramics using a 1030 nm femtosecond laser. Both the microdimple morphology, surface contact angle, and surface chemical structure are determined using optical microscopy, optical profilometry, contact angle measuring instrument, and X‐ray photoelectron spectroscopy (XPS). The effects of average laser power, scanning passes, and microdimple distribution density on both surface morphology and contact angle are also studied. Accordingly, the wettability surfaces of different gradients are processed by changing the microdimple distribution density, and the flow state of the cutting fluid on the gradient wettability surface is observed using a high‐speed camera. The results show that both the diameter and depth of the microdimple increase with the increase in the average laser power and scanning passes. As the average laser power increases, the surface contact angle gradually reduces and then increases. Moreover, because of the increase in scanning passes, the surface contact angle gradually decreases. The microdimple morphology is an important factor affecting the wettability of the sample surface. Reason construction of the surface microdimple distribution density can obtain different gradients of wettability surface. Furthermore, with a larger gradient, the wetting rate of the cutting fluid will be faster.

    Wettability Control on YW2 Cemented Carbide Surface by Femtosecond Laser Irradiation

    Abstract: The surface wettability control of cemented carbide tools is beneficial to the improvement of tool life and surface quality of workpieces in wet cutting. To clarify the correlation between the surface topography and wettability, squared microdimples are fabricated on the cemented carbide surface using a femtosecond laser. The dependencies of the side length, the depth, and the distribution density of squared microdimples on the surface topography and contact angle are studied. As the average laser power, and the number of scanning passes, increase, both the side length and depth of the squared microdimples increase. The contact angle decreases from hydrophilic to superhydrophilic. Moreover, the roughness height parameters have a great influence on the surface wettability, the larger the surface arithmetic average height, the smaller the kurtosis, the larger the skewness, and the better the hydrophilicity. The results of the scanning electron microscope (SEM) and energy‐dispersive spectrometer (EDS) reflect that the changes in the micro–nano protrusions, carbon, and oxygen elements cause deviation between the calculated contact angle and the actual contact angle. The friction coefficient of textured tools is lower than that of untextured tools at high sliding speed. Reasonable design of surface texture accurately controls surface wettability.

    Abstract: Background and purpose: Buyang Huanwu decoction (BYHWD) is widely used in the treatment of ischemic stroke in the recovery period , and many clinical trials have been reported, but its clinical efficacy and safety have not been fully evaluated. In this study, we conducted a systematic review and meta-analysis to evaluate the clinical efficacy and safety of BYHWD in the recovery period. Materials and methods: Eight databases, including CNKI, Wanfang Database, VIP Database, China Biomedical Literature Database, PubMed, Cochrane Library, EMBASE, and Web of Science, were searched from the establishment of the database to 13 April 2022. We selected all eligible randomized controlled trials of BYHWD in the treatment of ischemic stroke during the recovery period. Systematic review and meta-analysis were conducted in accordance with PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analysis) guidelines. The National Institutes of Health Stroke Score (NIHSS) was the primary outcome, and the Chinese Stroke Scale (CSS), activities of daily living (ADL), and adverse drug reaction (ADR) were the secondary outcomes. Results: A total of 39 randomized controlled trials were included, and 3,683 patients in the recovery period of ischemic stroke were recruited. Compared with conventional treatment alone, BYHWD combined with conventional treatment significantly decreased the NIHSS score (MD = -1.44, 95% CI: 1.75, -1.12, p & lt; 0.00001), the CSS score (MD = -1.18, 95% CI: 2.02, -0.34, p = 0.006), improved the ADL (MD = 4.33, 95% CI: 3.06, 5.61, p & lt; 0.00001), and did not increase the adverse reactions of patients (OR = 0.88, 95% CI: 0.48, 1.61, p = 0.67). Conclusion: BYHWD is an effective and safe therapy for the recovery of ischemic stroke. To further determine the efficacy and safety of BYHWD in the treatment of ischemic stroke in the recovery period, more high-quality, multicenter, and prospective RCTs are needed.
