Thermodynamic properties of vitreous electrodes in a Ni/NiP glass-crystal Galvanic cell

Autor: Ivan S. Gutzow, Nicolai B. Jordanov, Lothar Wondraczek

Publikováno v: Journal of Non-Crystalline Solids. 382:125-132

In the present paper, we present and discuss data on the thermodynamic properties of electrochemically deposited crystalline and vitreous metallic electrodes, focusing our attention on the model system of vitreous Ni/P alloys. Galvanic cells based on

Hippuric Acid as a Significant Regulator of Supersaturation in Calcium Oxalate Lithiasis: The Physiological Evidence

Autor: Stoyanka S. Atanassova, Ivan S. Gutzow

Publikováno v: BioMed Research International
BioMed Research International, Vol 2013 (2013)

At present, the clinical significance of existing physicochemical and biological evidence and especially the results we have obtained from our previousin vitroexperiments have been analyzed, and we have come to the conclusion that hippuric acid (C6H5

Variation of Avrami parameter during non-isothermal surface crystallization of glass powders with different sizes

Autor: R. Pascova, Isak Avramov, Ivan S. Gutzow, Lorenzo Arrizza, Alexander Karamanov

Publikováno v: Journal of Non-Crystalline Solids. 358:1486-1490

The influence of grain size on the surface crystallization kinetics is investigated by non-isothermal Differential Thermal Analysis and Scanning Electron Microscopy. For this purpose, different powder fractions of a model glass forming diopside via s

Thermodynamic properties of amorphous solids: The electrochemical approach

Autor: Nicolai B. Jordanov, Lothar Wondraczek, Ivan S. Gutzow

Publikováno v: Journal of Non-Crystalline Solids. 358:1239-1256

In the present contribution are critically analyzed and reexamined the possibilities to determine the thermodynamic properties of amorphous solids, of defect crystals and of glasses by means of electrochemical methods. After detailed theoretical cons

Refractory Alkali-Free Cristobalite Glass-Ceramics: Activated Reaction Sinter-Crystallization Synthesis and Properties

Autor: Georgi Avdeev, Ivan Penkov, Frank-Peter Ludwig, R. Pascova, Juern W. P. Schmelzer, Ivan S. Gutzow

Publikováno v: International Journal of Applied Glass Science. 3:75-87

A new approach for the synthesis of chemically stabilized β-cristobalite-like glass-ceramic materials is developed. It is based on an activated reaction sinter-crystallization process of compacted powder mixtures at relatively low temperatures (1400
