Textured macro- and mesoporous alumina samples designed in the presence of different surfactant types
(Springer, 2014-07-01)
This work presents a method that enables the synthesis of porous alumina in the presence of different types of surfactant. The method is based on a sol-gel transition, using surfactants and droplets of a nonpolar phase as ...
Microstructure and Thermal Conductivity of Porous Al2 O3-ZrO2 Ceramics
(2015-01-01)
The improvement on the development of porous ceramic materials has leaded to new technologies in thermal insulation, for example, composite materials for better performance of pressure vessels in rocket engines. Within ...
The energy-band structure of porous silicon studied with photoluminescence excitation and photoacoustic spectroscopy
(2000)
Porous silicon has been studied with photoluminescence, photoluminescence excitation, and photoacoustic spectroscopy. From the luminescence data, an energy-level diagram related to the luminescence is constructed. The ...
Controlling the porosity and crystallinity of MgO catalysts by addition of surfactant in the sol-gel synthesis
(2018-01-01)
This study presents an easy route to induce pore formation, increase the specific surface area and control the crystallite size of magnesium oxides obtained using the sol-gel method with addition of Pluronic P123 surfactant. ...
Rough 1D photonic crystals: A transfer matrix approach
(Elsevier Science, 2020-11)
Interfacial roughness is prevalent in 1D photonic crystals and other layered structures, but is not generally accounted for in their design nor the analysis of their optical properties due to a lack of simple theoretical ...
Porous silicene and silicon graphenylene-like surfaces: a DFT study
(Springer, 2018-01-05)
Nanoporous single-layers surfaces derived from silicene, named porous silicene (PS) and silicenylene (SC) have been studied via periodic density functional theory with a modified B3LYP functional combined with an all-electron ...
