AI-EXAFS: Physics-Informed Prediction of EXAFS from Atomic Structure. [PDF]
AI‐EXAFS presents a neural network to reproduce EXAFS. Trained on synthetic data and with a careful selection of the settings both for the physical representation of the system and following the experimental heuristic loss functions, the model is capable of reproducing EXAFS spectra for molecules from the tridimensional structure.

Influence of the pH in the stability of the silver coacervate by vitreous precursors
In this work, using coacervation process, the influence of the pH in the stability of the coacervates of the NaPO3/AgNO3/H2O system was studied. The coacervate domain was established using different concentrations of NaPO3 and AgNO3 and the influence of ...

Gallium-doped zinc oxide prepared by the Pechini method
Gallium-doped zinc oxide (ZnO:Ga) was prepared by the Pechini method from zinc citrate and gallium hydroxide. By this method, it is possible to synthesize crystalline ZnO:Ga by firing the polymeric precursor in air at 900ºC for four hours.
