A durable ZSM-5/SS composite tubular membrane for the selective separation of p-xylene from its isomers
(Elsevier Science, 2006-09)
A ZSM-5 membrane synthesized on a stainless steel porous tube was used for the separation of p-xylene from its isomers, m- and o-xylene. The membrane was prepared by secondary growth on the outer surface of the support. ...
Accurate calculation of the eigenvalues of non-uniforms strings and membranes
(Versita, 2012-11)
We describe a pseudospectral approach which combines a mapping procedure with the principle of minimal sensitivity to obtain accurate estimates for the eigenvalues of non-uniform strings and both uniform and nonuniform ...
Fouling behaviour of polyethersulfone UF membranes made with different PVP
(Elsevier Science, 2003-01-01)
Several polyethersulfone (PES) ultrafiltration membranes have been made with small quantities of polyvinyl-pyrrolidone (PVP) of different molecular weights to increase the permeability without a significant reduction in ...
Influence of a collagen membrane positioned subjacent the sinus mucosa following the elevation of the maxillary sinus. A histomorphometric study in rabbits
(Wiley, 2017)
OBJECTIVE: To evaluate the healing after elevation of the sinus mucosa when a collagen membrane was placed between the sinus mucosa and a xenograft used as filler. MATERIALS AND METHODS: Eighteen rabbits were used. Sinus ...
Interaction of gabaergic ketones with model membranes: A molecular dynamics and experimental approach
(Elsevier Science, 2018-08)
γ-Aminobutyric-acid receptor (GABA A -R), a membrane intrinsic protein, is activated by GABA and modulated by a wide variety of recognized drugs. GABA A -R is also target for several insecticides which act by recognition ...
Spin label EPR suggests the presence of cholesterol rich domains in cultured insect cell membranes
(Academic Press Inc Elsevier Science, 2018-11)
Different spin labels were incorporated to the membranes of cultured insect UFL-AG-286 cells in order to characterize their physical properties by Electron Paramagnetic Resonance spectroscopy (EPR). The spectrum of the ...
Procyanidins can interact with Caco-2 cell membrane lipid rafts: involvement of cholesterol
(Elsevier Science, 2013-11)
Large procyanidins (more than three subunits) are not absorbed at the gastrointestinal tract but could exert local effects through their interactions with membranes. We previously showed that hexameric procyanidins (Hex), ...
Interactions of flavan-3-ols and procyanidins with membranes: mechanisms and the physiological relevance
(Royal Society of Chemistry, 2015-01)
Flavonoids are a type of phenolic compound widely present in edible plants. A great number of health benefits have been ascribed to flavonoid consumption in the human population. However, the molecular mechanisms involved ...
A generalization of the membrane-plate analogy to non-homogeneous polygonal domains consisting of homogeneous subdomains
(Acoustical Society of America Institute of Physics, 2010-04)
The well-known membrane-plate analogy that relates the natural frequencies when dealing with polygonal homogeneous domains is herein extended to non-homogeneous systems comprised of homogeneous subdomains. The analogy is ...
Microporous titanosilicate ETS-10 membrane for high pressure CO2 separation
(Elsevier Science, 2010-05)
Membrane technology is expected to be an efficient process for CO 2 separation. Microporous titanosilicate ETS-10 membranes prepared by seeded hydrothermal synthesis are presented as candidates to CO2 separation from binary ...
