Native and Oxidized Starch for Adsorption of Nickel, Iron, and Manganese Ions from Water

open access: yesPolysaccharides, 2022
The adsorption of heavy metal ions from surface water with ecologically safe and biodegradable biopolymers is increasingly becoming an appealing research challenge. Starch as a biopolymer is exceptionally attractive to solve this problem for its low cost

Multilayer Density Analysis of Cellulose Thin Films

open access: yesFrontiers in Chemistry, 2019
An approach for the multilayer density analysis of polysaccharide thin films at the example of cellulose is presented. In detail, a model was developed for the evaluation of the density in different layers across the thickness direction of the film.

Proton NMR relaxometry as a useful tool to evaluate swelling processes in peat soils [PDF]

open access: yes, 2010
Dramatic physical and physico-chemical changes in soil properties may arise due to temperature and moisture variations as well as swelling of soil organic matter (SOM) under constant conditions.

Design of Friction, Morphology, Wetting, and Protein Affinity by Cellulose Blend Thin Film Composition

open access: yesFrontiers in Chemistry, 2019
Cellulose derivate phase separation in thin films was applied to generate patterned films with distinct surface morphology. Patterned polymer thin films are utilized in electronics, optics, and biotechnology but films based on bio-polymers are scarce ...

Development of swelling strain in smectite clays through exposure to carbon dioxide [PDF]

open access: yes, 2014
Smectites are common constituents of claystones, mudstones and shales and are often present in the caprocks and faults that seal potential CO2 storage reservoirs at depths up to 2 or even 3 km.

Swelling of polymer networks with topological constraints: Application of the Helmis-Heinrich-Straube model

open access: yeseXPRESS Polymer Letters, 2018
For the first time since its formulation in 1986, the theoretical approach proposed by Helmis, Heinrich and Straube (HHS model), which considers the contribution of topological restrictions from entanglements to the swelling of polymer networks, is ...

A Diagnostic Dilemma: Two Case Reports of Rare Presentations of Swelling in the Medial End of Clavicle [PDF]

open access: yesJournal of Orthopedics and Joint Surgery
Aim and background: Patients presenting with swellings in the medial end of the clavicle are rare. The most common differential diagnoses include trauma and, less likely, osteomyelitis, arthritis, or neoplasms.
