Summary: Two triazepine derivatives, AITT and EHTC, were successfully synthesized and demonstrated to be effective corrosion inhibitors for mild steel in 15% HCl medium. The inhibitors showed promising inhibiting performance, with AITT exhibiting higher efficiency than EHTC. The adsorption of the inhibitors on the metal surface played a key role in the protection mechanism. The inhibitors were found to be mixed-type inhibitors, as supported by potentiodynamic polarization experiments and Langmuir Adsorption isotherm analysis. The application of the inhibitors resulted in significant improvement in the damaged surface, as observed through surface topographical analysis. XPS analysis confirmed the presence of the inhibitors on the inhibited metal surface. Computational methods, including Monte-Carlo Simulation, DFT, and Fukui calculations, further supported the experimental findings.

Summary: This experimental study investigated the corrosion inhibition properties of spent coffee grounds activated carbon (CAP) in 1 M HCl acid medium on mild steel (MS). Experimental techniques such as polarization curves and electrochemical impedance spectroscopy (EIS) were used to evaluate the effectiveness of CAP as a corrosion inhibitor for mild steel in a molar hydrochloric acid solution. The adsorption process was confirmed through Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), energy dispersive X-ray spectrometry (EDX), and UV-visible analyses. The impedance and inhibition efficiency parameters were found to increase with the concentration of the inhibitors. The maximum inhibition efficiencies of CAPBM, CAPRhB, I, and CAP were approximately 90%, 89%, 88%, and 78%, respectively, at an optimum concentration of 1 g/L.

Summary: This study investigates the corrosion inhibition performance of a stable Schiff base, LPD, on mild steel in 1 M HCl solution. The results show that LPD exhibits high inhibition efficiency due to the presence of characteristic imine groups and heteroatoms. The inhibition mechanism involves adsorption on the steel surface, following the Langmuir isotherm model. The study also reveals the effects of temperature and LPD concentration on the inhibition efficiency.

Summary: Liver disease is a major cause of global mortality, and identifying biomarkers for diagnosing its progression is crucial for improving outcomes. Targeted mass spectrometry is a powerful tool for verifying biomarker candidates and clinical applications, particularly for glycoproteins translation. However, the limitation of analyzing only one sample per run has become apparent. In this study, a high-throughput intact N-glycopeptides quantification strategy was developed, allowing the validation of 20 samples per run with an average analysis time of 3 minutes per sample. The strategy was applied in a cohort of 461 serum samples and identified a panel of 10 IgG N-glycopeptides that have strong clinical utility in evaluating the severity of liver disease.
