Open AccesspH-responsive cellulose–chitosan nanocomposite films with slow release of chitosan
Cellulose–chitosan films were prepared using a physical method in which cellulose and chitosan were separately dissolved via freeze thawing in LiOH/urea and mixed in different proportions, the resulting films ...

Open AccessFrom surfactant to cellulose and DNA self-assembly. A 50-year journey
Surfactants have been the basis for applications in several industrial sectors for a long time. However, fundamental research was 50 years ago still limited to a small number of academic groups and even basic ...

Open AccessSpherical nanocomposite particles prepared from mixed cellulose–chitosan solutions
Novel cellulose–chitosan nanocomposite particles with spherical shape were successfully prepared via mixing of aqueous biopolymer solutions in three different ways. Macroparticles with diameters in the millime...

Dissolution state of cellulose in aqueous systems. 1. Alkaline solvents
The understanding of the state of dissolution of cellulose in a certain solvent is a critical step forward in the development of new efficient solvent systems for cellulose. Nevertheless, obtaining such inform...

Rheology of polyacrylate systems depends strongly on architecture
The relation between polymer architecture of polyacrylic acid (PAA) derivatives and the rheological properties is examined in aqueous systems with and without surfactant. The capability of PAA and its derivate...

Rationalizing cellulose (in)solubility: reviewing basic physicochemical aspects and role of hydrophobic interactions
Despite being the world’s most abundant natural polymer and one of the most studied, cellulose is still challenging researchers. Cellulose is known to be insoluble in water and in many organic solvents, but ca...

Temperature Induced DNA Compaction in a Nonionic Lamellar Phase
A nonionic lamellar phase was prepared using C10E3 in buffer solution at pH = 7.6. A suitable T4DNA concentration around 5 wt % was immobilized in a lamellar phase with 40 wt % C10E3. The mixed system...

Increasing anastomosis safety and preventing abdominal adhesion formation by the use of polypeptides in the rat
Postoperative adhesions can potentially be reduced using different anti-adhesive agents, though these drugs tend to compromise healing of an intestinal anastomosis. No method that significantly increases anast...

The association between a non-ionic microemulsion and hydrophobically modified PEG. A rheological investigation
The thickening effect of a hydrophobically modified polymer in an O/W microemulsion is investigated. The hydrophobically modified polymer is a triblock copolymer, alkyl end-capped poly(ethylene glycol) and the...

Phase Structures and Phase Diagrams of Some Surfactant Systems with Divalent Counterions: Effect of Ca2+ and Mg2+ Counterions on the Stability of Liquid Crystalline Phases
The phase behaviour of some surfactant systems with divalent counterions is examined using 2H nuclear magnetic resonance. Systems investigated are calcium octyl sulphate-decanol-water, calcium di-2-ethylhexyl sul...

Structure and Dynamics of Micelles and Microemulsions
The surface of amphiphilic aggregates consists of amphiphile head-groups, counterions and water molecules while the interior mainly contains the hydrocarbon chains. A review of the structure and dynamics of di...

Effect of NaCl on kinetics ofd-glucosamine uptake in yeasts differing in halotolerance
The initial rate ofd-glucosamine uptake by the non-halotolerant yeastSaccharomyces cerevisiae was approximately halved as the apparent half saturation constant (Km) and the apparent maximum velocity (Vmax) change...

Molecular and Ionic Behaviour at Water-Amphiphile Interfaces
In systems containing aggregates of amphiphilic compounds there is a spatial separation between the hydrocarbon chains and the water molecules. The decisive feature is the interface betwen the two distinctly d...
