Gellan gum fluid gels: influence of the nature and concentration of gel-promoting ions on rheological properties
(Springer, 2018-11)
Low-acyl gellan gum fluid gels were obtained using two different gel-promoting cations under the same processing conditions, and their rheological properties were investigated. For that reason, stress and frequency sweep ...

Interfacial rheology and conformations of triblock copolymers adsorbed onto the water-oil interface
(Elsevier, 2012)
The conformation and the dilatational properties of three non-ionic triblock PEO-PPO-PEO (where PEO is polyethyleneoxide and PPO is polypropyleneoxide) copolymers of different hydrophobicity and molecular weight were ...

Effect of temperature and shear on the microstructure of a microbial polysaccharide secreted by Sphingomonas species in aqueous solution
(Elsevier, 2018-10-15)
Diutan gum is a biological polymer produced by Sphingomonas sp. In aqueous solution it shows gel-like structure under quiescent conditions. However, the flow-induced evolution of its viscoelastic properties and its ...

Rheology, microstructural characterization and physical stability of W/α-PINENE/W emulsions formulated with copolymers
(Elsevier, 2018)
In this work the microstructure and the physical stability of emulsions containing α-pinene and gellan gum were studied as a function of Atlas™ G-5000/Atlox™ 4912 copolymer mass ratio, R, used as emulsifier. In order to ...

Transiciones microestructurales inducidas por cizalla en sistemas acuosos de un tensioactivo catiónico tipo esterqua
(Instituto Químico de Sarriá: Asociación de Químicos e Ingenieros, 2010)
Se presenta un estudio basado en técnicas reológicas y de microscopía electrónica de barrido de bajas temperaturas (cryo-SEM) sobre los cambios de microestructura provocados por el flujo en cizalla de dispersiones acuosas ...

Estudio reológico y análisis sensorial de cuatro detergentes comerciales denominados “detergente-gel”
(Asociacion de Quimicos, 2018)
Gel detergents possess some advantages compared to podwer detergents, such as easyness to transport, high eficiency considering number of washes per bottle and the reasonable use of water and package. In order to check ...
