Polarity-Based Sequential Extraction as a Simple Tool to Reveal the Structural Complexity of Humic Acids
(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 ...
Introducing the Newly Isolated BacteriumAneurinibacillussp. H1 as an Auspicious Thermophilic Producer of Various Polyhydroxyalkanoates (PHA) Copolymers-2. Material Study on the Produced Copolymers
(MDPI, 2020-06-05)
Aneurinibacillussp. H1 is a promising, moderately thermophilic, novel Gram-positive bacterium capable of the biosynthesis of polyhydroxyalkanoates (PHA) with tunable monomer composition. In particular, the strain is able ...
Introducing the Newly Isolated BacteriumAneurinibacillussp. H1 as an Auspicious Thermophilic Producer of Various Polyhydroxyalkanoates (PHA) Copolymers-1. Isolation and Characterization of the Bacterium
(MDPI, 2020-05-29)
Extremophilic microorganisms are considered being very promising candidates for biotechnological production of various products including polyhydroxyalkanoates (PHA). The aim of this work was to evaluate the PHA production ...
A simple technique for assessing the cuticular diffusion of humic acid biostimulants
(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. ...
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 ...
Multiscale experimental evaluation of agarose-based semi-interpenetrating polymer network hydrogels as materials with tunable rheological and transport performance
(MDPI, 2020-10-31)
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 ...
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 ...
