  • Speciation of tin ions in oxide glass containing iron oxide through solvent extraction and inductively coupled plasma atomic emission spectrometry after the decomposition utilizing ascorbic acid.: This study explores the speciation of tin ions in oxide glass, enhanced by hydrofluoric acid in the decomposition process for analytical purposes ( Saijo et al., 2022).


  • Physicochemical and morphological characterization of a glass ceramic treated with different ceramic primers and post-silanization protocols.: This research discusses the use of hydrofluoric acid in preparing glass ceramic surfaces to enhance their physicochemical properties for dental applications ( Moreno et al., 2019).


  • Chemical analysis of acidic silicon etch solutions I. Titrimetric determination of HNO(3), HF, and H(2)SiF(6).: This paper details a method for analyzing hydrofluoric acid concentrations in industrial etching solutions, providing critical insights into its effective use in silicon processing ( Henßge et al., 2007).


  • Structure of a novel phosphoglycolipid from Deinococcus radiodurans.: Hydrofluoric acid was utilized in the extraction processes that led to identifying unique phosphoglycolipids, contributing to biochemical research and applications ( Jürgens et al., 1986).
