Back to the basics: probing the role of surfaces in the experimentally observed morphological evolution of ZnO
MDPI (2023-03-08)Although the physics and chemistry of materials are driven by exposed surfaces in the morphology, they are fleeting, making them inherently challenging to study experimentally. The rational design of their morphology and ... -
Efecto del ZnO, ZrO2 y B2O3 en el proceso de clinkerización. Parte I. Reacciones de clinkerización y composición de los clínkeres.
CSIC (2008)El empleo de residuos cerámicos como materia prima alternativa en la fabricación del crudo de cemento Portland, aumenta el contenido de ZnO, ZrO2 y B2O3 en el clinker. Estos elementos se encuentran en la capa esmaltada ... -
Effect of type and amount of alumina as dopant over the densification and the electrical properties of zinc oxide ceramic electrodes
Elsevier (2021-02)Aluminum-doped zinc oxide (AZO) electrodes can be a good alternative to replace the expensive electrodes (Ti, ITO, FTO, etc.), which are used in the electrooxidation process to remove refractory and emergent contaminants ... -
Efficient Ni and Fe doping process in ZnO with enhanced photocatalytic activity: A theoretical and experimental investigation
Elsevier Ltd. (2022-08-01)Zn1-xNixO and Zn1-xFexO structures were synthesized by the microwave-assisted hydrothermal method. The best photocatalytic degradation of rhodamine B (RhB) and 4-nitrophenol (4-NP) were achieved by the Zn0.96Ni0.04O and ... -

Interplay of Optical, Morphological, and Electronic Effects of ZnO Optical Spacers in Highly Efficient Polymer Solar Cells
Wiley (2014-12-29)Optical spacers based on metal oxide layers have been intensively studied in poly(3-hexylthiophene) (P3HT) based polymer solar cells for optimizing light distribution inside the device, but to date, the potential of such ... -
Role of the Selective Contacts in the Performance of Lead Halide Perovskite Solar Cells
American Chemical Society (2014-01)The effect of electron- and hole-selective contacts in the final cell performance of hybrid lead halide perovskite, CH3NH3PbI3, solar cells has been systematically analyzed by impedance spectroscopy. Complete cells with ... -
Spray-Pyrolyzed ZnO as Electron Selective Contact for Long-Term Stable Planar CH3NH3PbI3 Perovskite Solar Cells
American Chemical Society (2018)Electron selective contacts (ESCs) play an important role in the performance of perovskite solar cells (PSCs). ZnO has attracted important attention as a good material for ESCs because of its matched energy levels with ... -
Synthesis of frits with ZnO made from zamak waste
Göller Verlag GmbH (2008)The feasibility of using a zinc oxide obtained from zamak waste recovery as a raw material for frit synthesis has been studied. For this purpose, three widely used types of frit in the ceramic sector, which are characterised ... -
ZnO/PVA Macroscopic Fibers Bearing Anisotropic Photonic Properties
Wiley-VCH (2012-10)Composite PVA/ZnO-nanorods fibers, synthesized through co-axial flux extrusion exhibit higher anisotropic photonic properties, both in absorption and emission, as a result of the collective alignment of the ZnO nanorods ...
