Journal ArticleDOI
Kinetics and equilibrium adsorption of methylene blue onto cotton gin trash bioadsorbents
TL;DR: In this article, a residual lignocellulosic biomass generated during the ginning process of cotton fibres, is proposed for valorization and application in environmental remediation.
Journal ArticleDOI
Accounting for Substrate Interactions in the Measurement of the Dimensions of Cellulose Nanofibrils.
TL;DR: A substantial flattening associated with the affinity of CNFs with the substrate corresponding to a highly anisotropic cross-sectional geometry (ellipsoidal) in the dried state is determined.
Journal ArticleDOI
Effects of alternative energy sources on bacterial cellulose characteristics produced by Komagataeibacter medellinensis.

TL;DR: A relationship of a higher BC production rate (provoked by ethanol and acetic acid adding) and changes in BC properties is demonstrated, which is the mechanism that provokes those changes.
Journal ArticleDOI
Laccase-Mediated Coupling of Nonpolar Chains for the Hydrophobization of Lignocellulose
TL;DR: The results help to better understand the mechanisms involved in laccase-mediated hydrophobization and provide a proof of a biotechnological platform for the development of value-added fiber products.
Journal ArticleDOI
Desorption of Low-Charge-Density Polyelectrolyte Adlayers in Aqueous Sodium n-Dodecyl Sulfate Solution.
TL;DR: Investigation of the association between low-charge-density polyelectrolytes adsorbed onto negatively charged surfaces and an anionic surfactant, sodium dodecyl sulfate, indicates that desorption starts at a SDS concentration of ca.
