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 ...
Gelcasting of alumina-chitosan beads
(ELSEVIER SCI LTD, 2011)
Several papers have reported the advantageous combination of chitosan and ceramic particles for such applications as biomimetic scaffolds, membranes, pollution remediation and gelcasting complex shapes. This work presents ...
Thermal analysis of chitosan based networks
(Elsevier B.V., 2005-11-10)
In this work two kinds of material were studied: chitosan cross-linked with glutaraldehyde and in a blend with PEO. The resulting products as well as chitosan and PEO raw materials, were analyzed by TG/DTG, DSC and DMTA ...
Chitosan-based systems aimed at local application for vaginal infections
(Elsevier B.V., 2021-06-01)
Vaginal administration is a promising route for the local treatment of infectious vaginal diseases since it can bypass the first-pass metabolism, drug interactions, and adverse effects. However, the commercial products ...
Evaluation of chitosan gel as antibiotic and photosensitizer delivery
(Informa Healthcare, 2008-01-01)
This work suggests the use of chitosan gel imbued with the photosensitizer Photogem and with the antibiotic Tetraclin as a possible drug delivery system. The results reveal a decrease in the photosensitizer level of toxicity. ...
Characterization of chemically modified chitosan microspheres as adsorbents using standard proteins (bovine serum albumin and lysozyme)
(Brazilian Soc Chemical EngSao PauloBrasil, 2007)
Effects of chitosan on ruminal fermentation, nutrient digestibility, and milk yield and composition of dairy cows
(2017-01-01)
Our objective was to evaluate the effects of providing increasing levels of chitosan on nutrient digestibility, ruminal fermentation, blood parameters, nitrogen utilisation, microbial protein synthesis, and milk yield and ...
New insights into physicochemical aspects involved in the formation of polyelectrolyte complexes based on chitosan and dextran sulfate
(2021-11-01)
Polyelectrolyte complexation is a technique based on interactions between polyelectrolytes of opposite charges driven by supramolecular interactions. Although many studies address the formation of polyelectrolyte complexes ...
Studies on the formation of complex coacervates between chitosan and alginate during microparticles preparation
(2005-07-01)
The formation of complex coacervates between chitosan and alginate was evaluated during microparticles formation. Mass ratio between polyelectrolytes and calcium chloride concentration were determinated by conductimetric ...
Synthesis, characterization and antifungal activity of quaternary derivatives of chitosan on Aspergillus flavus
(2013-01-15)
Two series of new chitosan derivatives were synthesized by reaction of deacetylated chitosan (CH) with propyl (CH-Propyl) and pentyl (CH-Pentyl) trimethylammonium bromides to obtain derivatives with increasing degrees of ...
