Dielectric relaxation of water in clay minerals

Vasilyeva M.; Gusev Y.; Shtyrlin V.; Greenbaum Gutina A.; Puzenko A.; Ishai P.; Feldman Y. (2014)

The study of confined water dynamics in clay minerals is a very important topic in aluminosilicate-surface chemistry. Aluminosilicates are among the most technologically versatile materials in industry today. Dielectric ...
Dielectric spectra broadening as a signature for dipole-matrix interactions. V. Water in protein solutions

Latypova L.; Puzenko A.; Levy E.; Feldman Y. (2020)

© 2020 Author(s). In this paper, the fifth of our series focused on the dielectric spectrum symmetrical broadening of water, we consider the solutions of methemoglobin (MetHb) in pure water and in phosphate-buffered saline ...
Effect of penetration enhancers on the dynamic behavior of phosphatidylcholine headgroups in liposomes

Ermolina I.; Smith G.; Ryabov Y.; Puzenko A.; Polevaya Y.; Nigmatullin R.; Feldman Y. (2000)

The results of a time-domain dielectric spectroscopy (TDDS) study of the effect of two skin penetration modulators on phosphatidylcholine (PC) bilayer vesicles are presented. The complex dielectric permittivity spectra of ...
Hydration of methemoglobin studied by in silico modeling and dielectric spectroscopy

Latypova L.; Puzenko A.; Poluektov Y.; Anashkina A.; Petrushanko I.; Bogdanova A.; Feldman Y. (2021)

The hemoglobin concentration of 35 g/dl of human red blood cells is close to the solubility threshold. Using microwave dielectric spectroscopy, we have assessed the amount of water associated with hydration shells of ...
Oxygenation state of hemoglobin defines dynamics of water molecules in its vicinity

Latypova L.; Barshtein G.; Puzenko A.; Poluektov Y.; Anashkina A.; Petrushanko I.; Fenk S.; Bogdanova A.; Feldman Y. (2020)

© 2020 Author(s). This study focuses on assessing the possible impact of changes in hemoglobin (Hb) oxygenation on the state of water in its hydration shell as it contributes to red blood cell deformability. Microwave ...
State of water in confinement near hydrophilic surfaces below the freezing temperature

Greenbaum A.; Puzenko A.; Vasilyeva M.; Feldman Y. (2013)

The main goal of the research is to find a relationship between the dynamic and the structural properties of water in hydrated heterogeneous systems. The results of dielectric spectroscopy studies of hydrated matrixes of ...
The dynamic crossover in dielectric relaxation behavior of ice Ih

Popov I.; Puzenko A.; Khamzin A.; Feldman Y. (2015)

© the Owner Societies 2015. The main mechanism of the dielectric relaxation process of ordinary hexagonal ice (ice Ih) and its temperature dependence remains unclear. The most interesting and as yet unexplained feature of ...
The variety of states of adsorbed water in heterogeneous materials and their dielectric response

Feldman Y.; Puzenko A.; Ishai P.; Greenbaum A.; Segev Y.; Vasilyeva M.; Gusev Y. (2013)

Whenever water interacts with another dipolar or charged entity, there exists a broadening of its dielectric relaxation peak. Often this broadening can be described by the phenomenological Cole-Cole (CC) spectral function. ...
