The kinetic features of the radical polymerization of trimethylmethacryloyloxyethylammonium methyl sulfate in micellar solutions of an oppositely charged surfactant—sodium dodecyl sulfate—are studied by NMR spectroscopy. It is shown that matrix p

We present results of an 11B and 29Si nuclear magnetic resonance (NMR) spectroscopy study of the local anion structure of a series of borosilicate glasses in the Rb2O–B2O3–SiO2 system with different R = [Rb2O]/[B2O3] and K = [SiO2]/[B2O3] molar r

The local structure of cesium-borosilicate glasses with various Cs2O and B2O3 proportions and constant SiO2 content (50 mol %) is studied with 11B, 29Si, and 133Cs MAS NMR spectroscopy. The portions of three- and four-fold Si atoms are determined, as

This paper considers the coordination state of boron and aluminum ions in barium aluminoborate glass with a constant ratio of BaO: B2O3 = 0.5 and a variable ratio of Al2O3: BaO = 0–3. The dependence of the concentrations of boron and aluminum atoms
