Using Natural Waste Material as a Matrix for the Immobilization of Enzymes: Chicken Eggshell Membrane Powder for β-Galactosidase Immobilization
(Springer, 2019)
Avian eggshell membranes are good candidates as a matrix for immobilization
procedures. Chicken eggshell, a waste material available from the poultry industry as a
byproduct, is a very safe and cheap raw material. While ...
Is the snail shell repair process really influenced by eggshell membrane as a template of foreign scaffold?
(Elsevier, 2016)
Biominerals are inorganic-organic hybrid composites formed via self-assembled bottom up processes under mild conditions. Biominerals show interesting physical properties, controlled hierarchical structures and robust ...
Modulation of (Na,K)-ATPase activity by membrane fatty acid composition: Therapeutic implications in human hypertension
(2014)
Oxidative stress (OS) plays a key role in the pathophysiology of essential hypertension and is associated with changes in the cell membrane fatty acid composition and fluidity. As (Na,K)-ATPase is modulated by the surrounding ...
Chicken eggshell membranes powder as a support for β-galactosidase 1 immobilization
(2018)
Increasing enzyme availability and stability may be addressed through enzyme 34 immobilization. Avian eggshells membranes are good candidates as a matrix for 35 immobilization procedures. Remarkably, the absence of cells ...
Integrated membrane process coupled with metal sulfide precipitation to recover zinc and cyanide
(MDPI, 2022)
In gold cyanidation plants, which include a zinc cementation process, there is a progressive increase in zinc content in the solution and a higher cyanide concentration in leaching tailings. Consequently, there are ...
An environmentally friendly triphasic catalytic system: Mn(salen) occluded in membranes based on PDMS/PVA
(ELSEVIER SCIENCE BV, 2010)
The commercially available Jacobsen catalyst, Mn(salen), was occluded in hybrid polymeric membranes based on poly(dimethylsiloxane) (PDMS) and poly(vinyl alcohol) (PVA). The obtained systems were characterized by UV-vis ...
Performance of the catalytic membrane reactors of different pore size with palladium as catalytic phase in hydrogenation and oxidation reactions
(2018)
The catalytic membrane reactors (CMR) were prepared using a commercial Hollow Fiber Membrane of corundum of 4 and 1400 nm and impregnated palladium. The tests performed were phenol hydrogenation, hydrogen peroxide generation ...
Screening of pervaporation membranes for the separation of methanol-methyl acetate mixtures: An approach based on the conceptual design of the pervaporation-distillation hybrid process
(Elsevier Science, 2017-12)
In this work, the pervaporation-distillation hybrid process is proposed to accomplish the separation of the azeotropic mixture methanol-methyl acetate.First, the separation performance of four membranes of a medium-high ...
