Summary: In this study, an environmentally friendly volatile corrosion inhibitor, lysine salts (LA), was prepared between graphene oxide (GO) layers using an in situ intercalation technique. The corrosion inhibition effect of LA was evaluated, and it was found that LA-GO2 achieved a 99.3% corrosion inhibition efficiency after composition optimization. The inhibition of the electrochemical anodic process on the surface of mild steel was the main reason for the high corrosion inhibition efficiency of LA-GO2. The properties of the surface film on the corroded steel were also characterized in detail to understand the corrosion inhibition mechanism of LA-GO2.

Summary: Metal organic frameworks (MOFs) with significant features such as large specific surface area, adjustable structure and function, regular pore arrangement, and abundant active sites, show great potential as anti-corrosion materials. In this study, a MOF-based inhibitor (M-BTC, M=Mn, Fe, and Co, and BTC=benzenetricarboxylate) was prepared through solvothermal conditions and demonstrated high efficiency in protecting mild steel from corrosion. The microstructure and physicochemical properties of the MOFs were analyzed using PXRD, FT-IR, N2 adsorption, and microscopic analysis. The MOF-based corrosion inhibitors form an adsorbed layer on the metal surface, leading to a decrease in the corrosion rate of mild steel in acidic media. The inhibition mechanisms follow the Langmuir adsorption isotherm, with a Mn-MOF based inhibitor achieving an inhibition efficiency of 94.7% at 200 ppm. The future outlook of using prepared MOFs for corrosion protection is discussed, offering new ideas for the development of MOF-based materials for future corrosion protection applications.

Summary: The corrosion performance of mild steel in 1M HCl solution was investigated in the presence of a green corrosion inhibitor called nonanedihydrazide. The inhibitor showed high adsorption on the steel surface and acted as a mixed inhibitor. The corrosion inhibition efficiency increased with an increase in the inhibitor concentration and decreased with an increase in temperature. Theoretical computations using density functional theory supported the experimental findings and provided insights into the inhibitive mechanism of nonanedihydrazide.

Summary: This work demonstrates how the current phase transition of atomic Bose-Einstein condensates in a trap can be controlled by applying an oscillatory driving field. The self-trapping effect in momentum space allows for a suppression of oscillations and a nearly constant directed current. Mean-field chaos serves as an indicator of the quantum phase transition. These findings are supported by an effective three-mode model.
