On the specific filtration mechanism of a mesoporous silica membrane, prepared with non-connecting parallel pores
(2005-04-01)
We report the singular filtration properties of an ultrafiltration membrane made with mesoporous silica that exhibits cylindrical pores aligned mostly normal to the support. This membrane supported on tubular commercial ...
On a Rational Performance Evaluation for the Development of Inorganic Membrane Technology in Gas Separation and Membrane Reactors
(Berkeley Electronic Press, 2016-02)
Inorganic membranes can be made of different materials. However, there have been only few reports on membrane evaluation to convert lab-scale membranes into a prototype for industrial applications. In order to fill this ...
Preparation of crosslinked chitosan magnetic membrane for cations sorption from aqueous solution
(2017-05-01)
A chitosan magnetic membrane was prepared in order to confer magnetic properties to the membrane, which could be used for the removal of cations from aqueous solution. The crosslinked magnetic membrane was compared with ...
Technological Monitoring Applied to Survey-Based on Brazilian Patent Applications about PEMFC

Anaerobic membrane bioreactors: Are membranes really necessary?
(Pontificia Universidad Católica de Valparaíso, 2008)
Deacidification of Soybean Oil Combining Solvent Extraction and Membrane Technology
(Hindawi Publishing Corporation, 2013-10)
The aim of this work was to study the removal of free fatty acids (FFAs) from soybean oil, combining solvent extraction (liquid-liquid) for the separation of FFAs from the oil and membrane technology to recover the solvent ...
Nanofibrous membranes for low-concentration CrVIadsorption: Kinetic, thermodynamic and the influence on ZFL cells viability
(2021-01-01)
There is a great demand to develop different techniques for the continuous removal, immobilization, and remediation of metallic ions from contaminated water. Human contamination by metallic ions could even occur by ingestion ...
Synthesis Polysulfone-Acetylethanol Ultrafiltration Membranes. Application to Oily Wastewater Treatment
(Science and Education Publishing, 2013-09)
Chemical functionalization of polymers after the synthesis of membranes has great importance for various applications separative processes of industrial or environmental interest. Polysulfone (PSf) is one of the most applied ...
Formation of SnO2 supported porous membranes
(Kluwer Academic Publ, 1997-01-01)
In this work, the effect of the substrate microstructure on the formation of SnO2 membranes and of the sintering conditions on their porosity have been analysed. Samples have been prepared by colloidal suspensions cast on ...
