Summary: The corrosion inhibition of SS 18/8 orthodontic wire in artificial saliva was studied with and without the presence of a 40mg esomeprazole tablet. The presence of the tablet increased the corrosion resistance of the wire, as indicated by an increase in polarisation resistance and a decrease in corrosion current. The presence of the tablet also caused changes in the surface properties of the wire, as observed through FTIR spectra and AFM micrograph images.

Summary: Developing an adsorbent with a fast adsorption rate is important for ensuring high adsorption capacity and selectivity of gold ions. In this study, two humic acid modified phenolic resin (SHAR and NSHAR) were prepared using a simple two-step method with water as solvent. These adsorbents can efficiently recover Au(III) from mixed metal solutions. The adsorption behavior and mechanism of Au(III) on SHAR and NSHAR were investigated, and it was found that the process belongs to multi-molecular chemical adsorption. The adsorption of Au(III) on SHAR and NSHAR is endothermic and spontaneous. Unlike conventional adsorbents, Au(III) is reduced to zero valent gold and deposited on the adsorbent. NSHAR achieves adsorption equilibrium in just 10 minutes with a high adsorption capacity of 927 mg center dot g(-1) (compared to SHAR, which takes 50 minutes and has a capacity of 1440 mg center dot g(-1)). This research provides a new approach for the quick and efficient recovery of gold.

Summary: The structure, surface, composition, and magnetic properties of a copper-nickel alloy thin film electrodeposited on a stainless steel substrate were studied. The deposition process first formed copper and then formed a copper-nickel alloy. A nickel-rich alloy that resists oxidation covered the underlying copper. The copper-nickel film showed a face-centered cubic structure with characteristics such as crystallite size, micro-strain, dislocation density, and stacking fault probability. Morphological and composition analysis showed that the deposited film adhered well to the substrate surface with microcracks and a stoichiometric ratio. The magnetic properties of the deposited film were evaluated.
