PVA Cryogel as model hydrogel for iontophoretic transdermal drug delivery investigations. Comparison with PAA/PVA and PAA/PVP interpenetrating networks
(Elsevier, Amsterdam, 2019)
The use of polyvinyl alcohol (PVA) cryogel as a model hydrogel for iontophoretic transdermal investigations is proposed. Due to the excellent combination of its properties, it could be used for evaluating iontophoretic ...
Bactericidal activity of Cu-, Zn-, and Ag-containing zeolites toward Escherichia coli isolates
(Springer Heidelberg, Heidelberg, 2017)
Two types of zeolites-natural clinoptilolite (NZ) and synthetic zeolite A (A)-were enriched with approx. 0.25 mmol of Cu(II), Zn(II), or Ag(I) ions, and the obtained materials (M-Z) were tested against three different ...
Thermal and rheological properties of unsaturated polyester resins-based composites
(Unsaturated Polyester Resins: Fundamentals, Design, Fabrication, and Applications, 2019)
Unsaturated polyester resins (UPR) are among the most commercially important thermosetting matrix materials for composites. This chapter summarizes the importance of the thermal and rheological properties of UPR. The ...
Simple One-Pot Synthesis of Fully Biobased Unsaturated Polyester Resins Based on Itaconic Acid
(Amer Chemical Soc, Washington, 2017)
For the preparation of fully biobased unsaturated polyester resins (UPRs), the replacement of styrene with alternate nonpetroleum-based monomers turned out to be one of the most challenging tasks. Its complexity lies in ...
The iron(III)-modified natural zeolitic tuff as an adsorbent and carrier for selenium oxyanions
(Elsevier, Amsterdam, 2014)
Se(IV) and Se(VI) anions are the dominant species of Se existing in aqueous systems. In this study, the iron(III)-modified natural zeolitic tuff (Fe-CLI) from the Serbian deposit Zlatokop has been investigated as an adsorbent ...
Supercapacitive Performances of Activated Highly Microporous Natural Carbon Macrofibers
(Electrochemical Soc Inc, Pennington, 2017)
Activated carbons with high specific surface area (even above 2000 m(2) g(-1)) and pronounced microporosity are prepared in two-stage process involving conventional carbonization of waste hemp fibers and subsequent activation ...
Synthesis and characterization of interpenetrating polymer network based on sodium alginate and methacrylic acid and potential application for immobilization of TiO2 nanoparticles
(Wiley, Hoboken, 2015)
An interpenetrating polymer network (IPN) based on the sodium alginate (A) and partially neutralized poly(methacrylic acid) (MAA) was prepared by free radical polymerization followed by additional cross-linking of sodium ...
