Coupling of narrow and wide band-gap semiconductors on uniform films active in bacterial disinfection under low intensity visible light: Implications of the interfacial charge transfer (IFCT)

“…6a. The CA varied from an initial value of 108 • at 10 s to 14 • within 300 s and disappears completely after 310 s. The surface energy of Ta 2 O 5 controls the surface CA [24]. The addition of Ag increases the hydrophobicity in the TaON/Ag film surface leading to longer absorption times for the water droplet as shown in Fig.…”

“…At longer deposition times, the Auger parameter at 725.65 eV suggests the formation of Ag 0 along a low amount of ionic silver. To separate the ionic states of Ag is not a simple matter due to the electrostatic charging of the sample but shifts of 0.2 eV or more are generally accepted as evidence for the change in the electronic configuration of a species detected by XPS [24]. Values for the Ag Auger parameter in Table 3 present the oxidation state of silver.…”

Solubility constants of metal oxides, metal hydroxides and metal hydroxide salts in aqueous solution

“…versus pH. Example: The solubility of y-Al(OH) 3 in HC10 4 and Na0H 19 was interpreted in a purely algebraic way, assuming the following reactions to take place:…”

“…A particular characteristic of aging is the sharp decrease in adsorption capacity 43 . Amorphous precipitates are converted into crystalline with formation of ScOOH in the case of scandium but presumably of Me(OH) 3 in the other cases. The Me(OH) 3 hydroxides described in the Iiterature were as a rule obtained at high temperatures with application of high pressures44.…”

The Me(OH) 3 hydroxides described in the Iiterature were as a rule obtained at high temperatures with application of high pressures44. In the dehydration of hydroxides to oxides, the occurrence of the intermediate MeOOH could be demonstrated in many instances.…”
