In this work, vitrification (the making of glasses) using lithium cobalt(III) oxide (LiCoO₂) as CAM and phosphorus pentoxide (P₂O₅) as glass former is explored for the first time to provide proof-of-concept. The raw materials were mixed in various proportions and melted in air atmosphere guided by <em>x</em>LiCoO₂-(100 – <em>x</em>)P₂O₅ with <em>x</em> = 20, 25, 30, 35 and 40 mol% formulas. The materials formed were subsequently characterized by X-ray diffraction (XRD), density, Fourier-transform infrared (FT-IR) spectroscopy, differential scanning calorimetry (DSC), and optical transmission measurements. The data supported glass formation in the compositional range explored, wherein the densities tended to increase with LiCoO₂ concentration. The FT-IR data suggested that incorporating LiCoO₂ at the expense of P₂O₅ leads to a network depolymerization effect evidenced for instance by the upsurge of the <em>v</em>_<em>as</em>(PO₃²⁻) band of end-of-chain PO₄ tetrahedra. Further, DSC showed that the glass transition temperatures increased steadily while glass stability decreased with increasing LiCoO₂ content. The optical measurements showed overall decreased transmittance ensued in connection with the presence of cobalt ions in different coordination environments. Herein, a potential for the glasses for developing blue bandpass filters is suggested.

The results show that this interaction leads to the degradation of thiosulfate ion on the gold (111) surface. Thiosulfate ion degradation happened through S-S bond breaking and led to formation of an adsorbed sulfur specie and a released SO₃ molecule (inter-bond angle of 120° and a bond length of 1.43 Å). Furthermore, the adsorbed sulfur specie was adsorbed at the hollow site on the gold (111) surface and bonded to three surface Au atoms (bond lengths: 2.33 Å). This interaction led to a rearrangement of the upper Au layer. To describe the nature of adsorbed sulfur specie, we have investigated the interaction of elemental sulfur (S⁰) and sulfide ion (S²⁻) on the gold (111) surface. The interaction of elemental sulfur and the gold (111) surface has a more similar geometry to sulfur specie product of thiosulfate ion degradation on the gold (111) surface. Also, by increasing the charge of system, the S-three Au atoms bond lengths has increased. It shows that by increasing the charge of system, the tendency of sulfur specie to the gold (111) surface has decreased. Based on the results, the rearrangement of the upper Au layer isn't because of the interaction of the thiosulfate ion.
