EPR, FTIR, Powder XRD and Optical Absorption Studies of Cu(II) Ion in Triaqua(1,10-Phenanthroline-k2 N,N′)(Sulfato-kO)Zinc(II)

Co-doping of hydroxyapatite with zinc and fluoride improves mechanical and biological properties of hydroxyapatite

“…Another band corresponding to the vibrational mode of ν 2 of (PO 4 ) 3À group was detected at 474 cm À 1 [62]. A small band was observed at 433 cm À 1 in Zn 2 þ containing samples [64].…”

Structural and mechanical characteristics of nanohydroxyapatite doped with zinc and chloride

“…There was not any significant shift for the band at 473 cm −1 . There was a small band at 433 cm −1 in Zn 2+ containing samples 36. Therefore, this band was assigned to Zn–O symmetrical stretching band (Fig.…”

“…There was a small band at 433 cm 21 in Zn 2z containing samples. 36 Therefore, this band was assigned to Zn-O symmetrical stretching band (Fig. 5c).…”

pH‐Specific Halide‐Dependent Materials from ZrIV/Hydroxycarboxylic Acid/Aromatic Chelator Reactivity: Architecture–Lattice Dimensionality and Spectroscopic Fingerprint Relations

“…This is attested to by the X‐ray crystal structures of 1 – 4 . The vibrations at 1665 cm –1 for 1 , 1660 cm –1 for 3 , and 1667 cm –1 for 4 are characteristic of the guanidinium cation28 and correspond to ν(C–N) vibrations, whereas the bands observed at 1549, 846, and 716 cm –1 for 4 have been assigned to 1,10‐phenanthroline stretches 29,30. Furthermore, ν(Zr–O) vibrations are present at 522 cm –1 for 1 , 507 cm –1 for 2 , 521 cm –1 for 3 , and 509 cm –1 for 4 ,31,32 whereas the bands observed at 691 cm –1 for 1 and 705 cm –1 for 2 have been assigned to ν(Zr–F) vibrations 33.…”
