Plasma nanocoatings developed to control the shear strength of polymer composites
(MDPI, 2019-07-15)
All reinforcements for polymer-matrix composites must be coated with a suitable material in the form of thin film to improve compatibility and interfacial adhesion between the reinforcement and the polymer matrix. In this ...
Hydrogels with micellar hydrophobic (nano)domains
(FRONTIERS MEDIA SA, 2015-10-31)
Hydrogels containing hydrophobic domains or nanodomains, especially of the micellar type, are reviewed. Examples of the reasons for introducing hydrophobic domains into hydrophilic gels are given; typology of these materials ...
Rates of Reactions as a Mathematical Consequence of the Permanence of Atoms and the Role of Independent Reactions in the Description of Reaction Kinetics.
(Frontiers, 2018-09-01)
Linear algebra treatment of the permanence of atoms (mass conservation) naturally leads to the transformation of formation or destruction rates of components of a reaction mixture into rates of reaction steps, which are ...
Lignitic humic acids as environmental friendly adsorbent for heavy metals
(Hindawi, 2017-03-05)
Huminové kyseliny jako součást humusu se účastní transportu prospěšných i škodlivých druhů látek v přírodě. Díky jejich struktuře a vlastnostem mohou interagovat s kovovými ionty a tvořit s nimi relativně stabilní komplexy. ...
Preparation of ultra-low volume weight autoclaved aerated concrete
(University of Chemistry and Technology, Prague, 2017-01-31)
Autoclaved aerated concrete is a modern construction material that gains its popularity especially due to its thermal insulation performance resulting from low volume weight and porous structure with sufficient mechanical ...
Thermodynamic Driving Forces and Chemical Reaction Fluxes; Reflections on the Steady State
(MDPI, 2020-02-01)
Molar balances of continuous and batch reacting systems with a simple reaction are analyzed from the point of view of finding relationships between the thermodynamic driving force and the chemical reaction rate. Special ...
Fluorescence study of freeze-drying as a method for support the interactions between hyaluronan and hydrophobic species
(PLOS, 2017-10-03)
A freeze-drying method enabling solubilization of hydrophobic species in aqueous solutions of native hyaluronan is described. The method is based on opening the access to supposed hydrophobic patches on hyaluronan by ...
Production of Polyhydroxyalkanoates Using Hydrolyzates of Spruce Sawdust: Comparison of Hydrolyzates Detoxification by Application of Overliming, Active Carbon, and Lignite
(MDPI AG, 2017-05-28)
Polyhydroxyalkanoates (PHAs) are bacterial polyesters which are considered biodegradable alternatives to petrochemical plastics. PHAs have a wide range of potential applications, however, the production cost of this ...
Cement Kiln By-Pass Dust: An Effective Alkaline Activator for Pozzolanic Materials
(MDPI, 2018-09-19)
Cement kiln by-pass dust (CKD) is a fine-grained by-product of Portland clinker manufacturing. Its chemical composition is not suitable for returning back into feedstock and, therefore, it has to be discharged. Such an ...
Thermodynamic analysis of chemically reacting mixtures – comparison of first and second order models
(Frontiers, 2018-03-01)
Recently, a method based on non-equilibrium continuum thermodynamics which derives thermodynamically consistent reaction rate models together with thermodynamic constraints on their parameters was analyzed using a triangular ...
