Developing corrosion inhibitors with low toxicity, eco-friendly, favorable water solubility, long-term, and efficiency is essential to inhibit metal corrosion.Herein, Eupatorium adenoprum leaves (EAL) extract is prepared via a pure water extraction method, and its inhibition for copper in 0.5 M H2SO4 is explored for the first time.The EIS and polarization curve results show that EAL extract can enhance the film and charge transfer resistance and reduce the c.d. of copper.After 48 h immersion, the inhibition efficiency value of 1000 mg/L EAL extract still reaches 97.7%, demonstrating that EAL extract presents long-term and dependable protection for copper in harsh acidic solutionThe weight loss, SEM/EDS, and AFM results are consistent with the above conclusion.According to Langmuir adsorption and theor. calculations, the interaction in EAL extract mols./copper substrate is discussed in detail.Thanks to the physicochem. adsorption effect, a monolayer EAL extract protective film is formed on copper surface.Furthermore, the crucial active adsorption sites are unsaturated double-bond, aromatic rings, carbonyl groups, and heteroatom in EAL extract mols.Ultimately, we expect this study to offer theor. support for developing new eco-friendly inhibitors and facilitate their application in industrial pickling environments.

Sichuan Shai vinegar, a distinctive condiment from Southwest China, is produced through open-air solid-state fermentation, employing a unique Chinese herbal medicine mixture (Yaoqu) as the fermentation starter.Despite its culinary significance, the dynamics and roles of fungal communities within the Cupei fermentation phase remain understudied.This study employed high-performance liquid chromatog. (HPLC) to quantify 11 organic acids and 17 amino acids, revealing a significant increase in organic acid content from 2.56 g/100 g-17.47 g/100 g dry weight and a gradual elevation in free amino acid content from 0.53 g/100 g-5.59 g/100 g throughout the fermentation process.Headspace solid-phase microextraction coupled with gas chromatog.-mass spectrometry (HS-SPME/GC-MS) identified 85 volatile flavor compounds, predominantly consisting of 2 alcs., 10 acids, 29 esters, 4 ketones, 6 aldehydes, and 14 other types.High-throughput sequencing facilitated the identification of key microorganisms, with Lichtheimia, Brettanomyces, Pichia, Saccharomyces, Kazachstania, and Syncephalastrum emerging as the most abundant fungal genera.Correlation anal. revealed significant pos. correlations between 20 fungi and 11 organic acids, 24 fungi and 16 amino acids, and 50 fungi and 76 volatile flavor compoundsNotably, Lichtheimia, Pichia, and Brettanomyces were identified as the most influential in flavor metabolismThese findings elucidate the microbial metabolic mechanisms during Sichuan Shai vinegar fermentation, laying a foundation for further research and potential applications in vinegar production

Unlocking seismic slope stability for risk assessment

Article

Slope instability represents a substantial secondary hazard post-earthquake, leading to considerable socio-economic losses from the destruction of structures, infrastructure, and human lives. This study addresses the urgent need for precise evaluation of seismic slope stability, a subject that has gained significant attention in earthquake engineering over the past decade. A theoretical framework is proposed that utilizes an improved Sarma method, estimating seismic forces and safety factors based on limit equilibrium theory. A Python-based implementation enhances both computational efficiency and reliability. The enhanced method is validated against the pseudo-static approach, exhibiting strong performance. Moreover, critical elements affecting slope stability, such as slope characteristics and seismic motion parameters, are examined. Although the findings predominantly concentrate on rocky slopes, next research intends to broaden the method's application to multiple slope types, hence facilitating more thorough and effective stability evaluations across different geological contexts.•Deriving seismic slope safety factors based on improved Sarma and Pseudo static methods.•Developing Python programs based on the improved Sarma safety factor method.•Assessing seismic rock slope stability based on calculated Safety Factors.
