Photoluminescence emission at room temperature in zinc oxide nano-columns
(Elsevier B.V., 2014-02-01)
Hydrothermal microwave method (HTMW) was used to synthesize crystalline zinc oxide (ZnO) nano-columns at the temperature of 120 degrees C with a soaking time of 8 min. ZnO nano-columns were characterized by using X-ray ...

Polarity-Induced Selective Area Epitaxy of GaN Nanowires
(Amer Chemical Soc, 2017-01-01)
We present a conceptually novel approach to achieve selective area epitaxy of GaN nanowires. The,approach is based on the fact that these nanostructures do not form in plasma-assisted molecular beam epitaxy on structurally ...
Molecular Beam Epitaxy of GaN Nanowires on Epitaxial Graphene
(Amer Chemical Soc, 2017-09-01)
We demonstrate an all-epitaxial and scalable growth approach to fabricate single-crystalline GaN nanowires on,graphene by plasma-assisted molecular beam epitaxy. As substrate, we explore several types of epitaxial graphene ...

Influencia de condiciones de síntesis sobre microestructura y fotorrespuestas de nanocolumnas de dióxido de titanio para aplicación en water splitting
(Universidad de los AndesIngeniería QuímicaFacultad de IngenieríaDepartamento de Ingeniería Química, 2018)
La separación fotocatalítica del agua en hidrógeno y oxígeno, conocido como water splitting es una alternativa prometedora para la obtención de energías renovables. La utilización de ánodos con morfologías1D (nanocolumnas) ...
Room-temperature volatile organic compounds sensing based on WO3·0.33H2O, hexagonal-WO3, and their reduced graphene oxide composites
(2016-01-01)
Nanostructured orthorhombic WO3·0.33H2O, hexagonal h-WO3 and their RGO composites (RGO-WO3·0.33H2O and RGO-h-WO3) are reported for the purpose of efficient sensing of volatile organic compounds (VOCs) (e.g. acetone, methanol, ...
Design of nanostructured WO3·0.33H2O: Via combination of ultrasonic spray nozzle and microwave-assisted hydrothermal methods for enhancing isopropanol gas sensing at room temperature
(2017-01-01)
Hierarchical WO3·0.33H2O nanocolumns were prepared by a simple combination of ultrasonic spray nozzle (USN) and microwave-assisted hydrothermal (MAH) methods. The USN step promoted a high nucleation rate of H2WO4 clusters, ...
