Summary: In this research, sodium gluconate-loaded chitosan microspheres (SG/CM) were prepared using negative pressure impregnation after hydrothermal synthesis of chitosan microspheres (CM) with vanillin (VA). The structures and morphologies of the prepared materials were analyzed using FTIR, SEM, and TEM. The thermogravimetric characterization showed that loading sodium gluconate enhanced the thermal stability. The corrosion inhibition performance of CS, CM, and SG/CM in 0.1 mol/L HCl was investigated using EIS and PDP tests, with SG/CM showing the highest inhibition efficiency.

Summary: This study aims to develop a new formulation based on chitosan derivatives for efficient and environmentally friendly corrosion inhibition of mild steel in 1 M HCl. The performance of chitosan-5-HMF as a corrosion inhibitor was evaluated through electrochemical tests and molecular dynamics simulations. The results showed that chitosan-5-HMF3 exhibited excellent inhibition performance with an efficiency of 97.01% at 200 mg/L, acting as an anode-based mixed inhibitor. SEM and contact angle analysis confirmed the formation of a compact chitosan-5-HMF film on the steel surface, while molecular dynamics simulations revealed a strong parallel adsorption of chitosan-5-HMF on the metal surface.

Summary: In this study, thiosemicarbazide chain was used to modify the imidazole ring and improve the inhibition effect of imidazole compound, resulting in an effective corrosion inhibitor for mild steel in HCl medium. The inhibition performance of this inhibitor, called imidazol-4-methylimine thiourea (MIT), was evaluated through various tests, showing an inhibition efficiency of 93.7%. The corrosion inhibition mechanism of MIT molecules is mainly attributed to the shielding effect of the MIT-adsorption film with multiple anchors and the reduction of attacking ions.

Summary: Crosslinking affects the mechanical behavior and tissue metabolism of collagen-based tissues. Aging and diabetes alter the crosslinking type and density, thus changing tissue properties. High-connectivity enzymatic crosslinking and advanced-glycation end-products result in uniform deformation under daily activity, while low-connectivity enzymatic crosslinking does not. High-connectivity model displays more sliding, while AGEs induce instability in structures near the binding sites.

Summary: The potential of multi-layer nanoemulsions for improving the cellular uptake, antioxidant activity, and in vitro bioaccessibility of alpha-tocopherol was examined. The results showed that the multi-layer nanoemulsions significantly enhanced the cellular uptake and antioxidant activity of alpha-tocopherol compared to free coumarin 6. Furthermore, the use of chitosan and dextran sulfate as wall materials in the multi-layer nanoemulsions led to even higher cellular uptake, in vitro bioaccessibility, and antioxidant activity of alpha-tocopherol.
