Thermodynamic Analysis of the Landolt-Type Autocatalytic System 

Pekař, Miloslav (MDPI, 2021-10-28)
A recent work demonstrated on the example of the Landolt-type reaction system how the simplest autocatalytic loop is described by the kinetic mass action law and proper parametrization of direct and autocatalytic pathways. ...

Polarity-Based Sequential Extraction as a Simple Tool to Reveal the Structural Complexity of Humic Acids 

Enev, Vojtěch; Sedláček, Petr; Kubíková, Leona; Sovová, Šárka; Doskočil, Leoš; Klučáková, Martina; Pekař, Miloslav (MDPI, 2021-03-19)
A sequential chemical extraction with a defined series of eluotropic organic solvents with an increasing polarity (trichloromethane < ethyl acetate < acetone < acetonitrile < n-propanol < methanol) was performed on peat-bog ...

A simple technique for assessing the cuticular diffusion of humic acid biostimulants 

Smilková, Marcela; Smilek, Jiří; Kalina, Michal; Klučáková, Martina; Pekař, Miloslav; Sedláček, Petr (BMC, 2019-07-31)
Background: Experimental determination of the extent and rate of transport of liquid humates supplied to plants is critical in testing of physiological effects of such biostimulants which are often supplied as foliar sprays. ...

Fluoride Anion Binding by Natural Lignite (South Moravian Deposit of Vienna Basin) 

Pekař, Miloslav (Springer-Verlag, 2009-01-01)
Natural lignite from South Moravia was tested for the sorption of fluoride anion in concentration range from 0.05 to 0.8 mmol/l. The lignite removes majority of fluorides and only about 13% of sorption is reversible upon ...

Macroscopic derivation of the kinetic mass-action law 

Pekař, Miloslav (Springer-Verlag, 2010-01-01)
Using several reaction examples with experimentally determined rate equations, traditional mass action rate equations are shown to be simplified forms of polynomial approximation to a general rate function derived by ...

Aggregation behavior of novel hyaluronan derivatives-a fluorescence probe study 

Mravec, Filip; Pekař, Miloslav; Velebný, Vladimír (Springer-Verlag, 2008-11-01)
Aggregation properties of hydrophobized hyaluronan (hHA) in different molecular weights and degree of substitution were studied by pyrene and perylene fluorescence method. The critical aggregation concentration (cac) was ...

Detailed balance in reaction kinetics - consequence of mass conservation? 

Pekař, Miloslav (Springer-Verlag, 2007-01-01)
Detailed balance condition for triangular isomerisation mechanism is derived from the more general permanence of atoms, consequently, it should be viewed as a special equilibrium result of mass conservation.

Compositional and Temperature Effects on the Rheological Properties of Polyelectrolyte–Surfactant Hydrogels 

Smilek, Jiří; Jarábková, Sabína; Velcer, Tomáš; Pekař, Miloslav (MDPI, 2019-05-27)
The rheological properties of hydrogels prepared by physical interactions between oppositely charged polyelectrolyte and surfactant in micellar form were studied. Specifically, hyaluronan was employed as a negatively charged ...

Determination of Critical Parameters of Drug Substance Influencing Dissolution: A Case Study 

Bojňanská, Erika; Kalina, Michal; Pařízek, Ladislav; Bartoníčková, Eva; Opravil, Tomáš; Veselý, Michal; Pekař, Miloslav; Jampílek, Josef (Hindawi Publishing Corporation, 2014-09-15)
The purpose of this study was to specify critical parameters (physicochemical characteristics) of drug substance that can affect dissolution profile/dissolution rate of the final drug product manufactured by validated ...

Gradient Hydrogels—The State of the Art in Preparation Methods 

Zinkovska, Natalia; Smilek, Jiří; Pekař, Miloslav (MDPI, 2020-04-21)
Gradient hydrogels refer to hydrogel materials with a gradual or abrupt change in one or some of their properties. They represent examples of more sophisticated gel materials in comparison to simple, native gel networks. ...
