The study includes various analytical techniques, like SEM, weight loss, electrochemical techniques, and density functional theory (DFT) to evaluate the efficacy of expired febuxostat as a corrosion inhibitor for steel in 0.5 M HCl solution. The EIS and PDP curve results showed a direct correlation between the concentration of Febuxostat and the inhibition efficiency.

We find that the (UC) nanophosphor LaPO4: Ce3+/Ho3+allows a strong 980 nm laser stimulation, causing the UC emission spectra to exhibit prominent Ho3+ ion resulting in peaks at 460, 542 and 650 nm as well as weak emission peaks at 300–360 nm. Future applications for these co-doped Ce3+ and Ho3+ ion monoclinic LaPO4 nanocrystals are anticipated to include better optical materials. Ultimately, many potential uses in various industries, from sophisticated display technologies to biomedical imaging and beyond, are made possible by the production and characterisation of co-doped Ce3+/Ho3+ ion nanophosphors in LaPO4 matrices.
