How the Supramolecular Nature of Lignohumate Affects Its Diffusion in Agarose Hydrogel
(MDPI, 2020-12-10)
Lignohumate, as an industrially produced analog of natural humic substances, is studied from the point of view of its diffusion properties. This work focuses on its permeation ability, important in agricultural and ...
Agarose Hydrogels Enriched by Humic Acids as the Complexation Agent
(MDPI, 2020-03-19)
The transport properties of agarose hydrogels enriched by humic acids were studied. Methylene blue, rhodamine 6G and Cu(II) ions were incorporated into hydrogel as diffusion probes, and then their release into water was ...
How Humic Acids Affect the Rheological and Transport Properties of Hydrogels
(MDPI, 2019-04-19)
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 ...
Controlling the internal microstructure and properties of physically cross-linked PVA hydrogels by the rate of freezing
(TANGER Ltd., 2021-01-01)
PVA hydrogels can be formed via physical crosslinking (e.g. by cyclic freezing/thawing of aqueous polyvinyl alcohol solutions) or with a chemical cross-linker. Physical crosslinking is more useful for biomedical applications ...
