Amorphous-to-crystalline transition of thin-film TiO2 precursor films to brookite, anatase, and rutile polymorphs

Crystallization Behavior of Zinc-Doped Nb2O5 Thin Films Synthesized by Atomic Layer Deposition

“…The m value of 4.4 × 10 –5 is related to the nucleation and growth rate. When converted to units of 1/s, as in ref , our value of 30 × 10 –3 1/s is similar to values obtained for amorphous to crystalline transformation of TiO 2 .…”

“…According to the JMAK model, isothermal crystallization ( X ) of the film is related to the annealing time ( t ) by the equation where m and n are fitting parameters that are related to the kinetics of the crystallization process. The n fitting parameter has been shown to be related to the dimensionality of the growth, with modifications made to account for thin films. , …”

“…Our n value, which is related to the dimensionality of the growth, is 2.86. Given the thin film nature of our samples, we presume that growth dimensionality transitions from a three-dimensional nucleation and initial growth, followed by a two-dimensional growth once the crystalline islands reach the film thickness. − …”

Green Synthesis via Eucalyptus globulus L. Extract of Ag-TiO2 Catalyst: Antimicrobial Activity Evaluation toward Water Disinfection Process

“…The Ag 0 NP and TiO 2 synthesis by conventional methods has been widely reported and includes chemical reduction [ 34 ], sol–gel [ 35 , 36 ], microwave-coupled sol–gel [ 37 , 38 ], sonochemistry-coupled sol–gel [ 38 , 39 ], PLD [ 40 , 41 ], and sputtering [ 42 , 43 ], to mention just the most representative. Moreover, the green synthesis of both materials in a separate way has been widely studied with different plants, fungi, and microorganism extracts [ 10 , 12 , 44 , 45 , 46 , 47 , 48 , 49 , 50 , 51 , 52 , 53 , 54 , 55 , 56 , 57 ].…”
