TL;DR: In this paper, Nanocrystalline monoliths of Er doped TiO2 were prepared by the sol-gel technique, by controlling the Er-doping levels into the TiO 2 precursor solution.

TL;DR: In this paper, the ability of composite edible coatings to preserve the quality of guava fruit (Psidium guqjava L.) at 20°C was studied for a period of 15 days.

TL;DR: In this paper, the physical properties of different biopolymers films were evaluated by the Open Photoacoustic Cell method; also, their mechanical properties such as tensile strength, elongation, and Young's modulus were measured by X-ray diffraction and microstructure through atomic force microscopy in contact mode.

TL;DR: The Carreau-Yasuda model fitted best the viscosity-shear rate data of all the emulsions as discussed by the authors, and the surface morphology of the edible films, analyzed by Atomic Force Microscopy (AFM), exhibited a strong dependence on the CaCl 2 concentration.

TL;DR: The optical properties of the R6G-doped thin films were characterized by photoacoustic, excitation, and fluorescence spectroscopies as discussed by the authors, and the optical absorption of undoped rutile-phase bulk TiO2 was calculated and compared to the experimental results.
