Journal ArticleDOI
Urease-catalyzed carbonate precipitation inside the restricted volume of polyelectrolyte capsules
Alexei Antipov,Dmitry G. Shchukin,Yuri Fedutik,Irina S Zanaveskina,Vera V. Klechkovskaya,Gleb B. Sukhorukov,Helmuth Möhwald +6 more
TL;DR: In this article, a biomimetic approach for performing CaC0 3 synthesis exclusively inside micron-sized polyelectrolyte capsules, based on the fermentative formation of a precipitative agent (CO 2 3 - anion) by urease-catalyzed urea hydrolysis, was developed.
Journal ArticleDOI
Polymorphic Modifications of Chitosan
Yulija G. Baklagina,Vera V. Klechkovskaya,S. V. Kononova,Valentina A. Petrova,Daria N. Poshina,Anton S. Orekhov,Anton S. Orekhov,Yury A. Skorik,Yury A. Skorik +8 more
TL;DR: In this article, the analysis of the crystal structures of chitosan, its main polymorphic modifications, and its characteristic mutual chain packing and hydrogen bond systems in the crystalline regions of conformers is presented.
Journal ArticleDOI
Stability of Ag nanoparticles dispersed in amphiphilic organic matrix
TL;DR: In this article, high-resolution transmission electron microscopy (HRTEM) and X-ray energy-dispersive (EDS) microanalysis were used to bring chemical and structural information in a study of the properties and stability of thin-film nanocomposite whih consisted of Ag nanoparticles dispersed in water-soluble organic matrix poly(N-vinyl-2-pyrrolidone).
Journal ArticleDOI
Poly(acrylamide) gels with embedded magnetite nanoparticles
S. G. Starodoubtsev,E. V. Saenko,Alexei R. Khokhlov,Vladimir Volkov,K. A. Dembo,Vera V. Klechkovskaya,Eleonora V. Shtykova,Irina S Zanaveskina +7 more
TL;DR: In this paper, a method was developed for the preparation of magnetite nanoparticles in a matrix of poly(acrylamide) gel, and the average size of the particles, d, calculated from the halfwidth of the diffraction peaks, is of the order of 10 nm.
Journal ArticleDOI
Pervaporation membranes of a simplex type with polyelectrolyte layers of chitosan and sodium hyaluronate.
S. V. Kononova,E. V. Kruchinina,Valentina A. Petrova,Yulia G. Baklagina,Vera V. Klechkovskaya,Anton S. Orekhov,Elena N. Vlasova,Elena N. Popova,G. N. Gubanova,Yury A. Skorik +9 more
TL;DR: Testing of the transport properties of the CS/HA film in pervaporation (PV) separation using different compositions of ethanol-water mixtures indicated that the multilayer membrane was selective across a wide range of concentrations in the feed.
