A simple technique for assessing the cuticular diffusion of humic acid biostimulants
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. ...
Compositional and Temperature Effects on the Rheological Properties of Polyelectrolyte–Surfactant Hydrogels
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 ...
Gradient Hydrogels—The State of the Art in Preparation Methods
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. ...
How Humic Acids Affect the Rheological and Transport Properties of Hydrogels
Huminové kyseliny jsou považovány za látky s tzv. supramolekulární strukturou, jež je základem jejich unikátních vlastností a fungování v přírodě. Naše studie potvrdila, že již malý přídavek těchto látek do agarozových ...
Multiscale experimental evaluation of agarose-based semi-interpenetrating polymer network hydrogels as materials with tunable rheological and transport performance
This study introduces an original concept in the development of hydrogel materials for controlled release of charged organic compounds based on semi-interpenetrating polymer networks composed by an inert gel-forming polymer ...
