Rheology and Structures of EO-PO-EO Block Copolymers in Aqueous Solutions
Aqueous solutions of a Pluronic copolymer P104 have been investigated by rheological techniques in order to characterize its gelation and its gel properties. P104 solutions have a low viscosity at low temperatures but form an elastic gel at physiological temperatures. Elastic moduli are of the order 10 kPa with a significant yield stress. Possible use of P104 to prevent flow in pipes or blood v...
متن کاملPo - Spaces
Locally partial-ordered spaces (local po-spaces) have been used to model concurrent systems. We provide equivalences for these spaces by constructing a model category containing the category of local po-spaces. We show the category of simplicial presheaves on local po-spaces can be given Jardine's model structure, in which we identify the weak equivalences between local po-spaces. In the proces...
متن کاملTemperature-controlled and aerosol-assisted synthesis of aluminium organophosphonate spherical particles with uniform mesopores.
Spray-drying of clear precursor solution containing inorganic-organic hybrid species and EO(n)PO(m)EO(n) triblock copolymer at low temperature, followed by treatment in acetone to remove the triblock copolymer, afforded spherical particles of aluminium organophosphonate (AOP) with uniform mesopores.
متن کاملOn (po-)torsion free and principally weakly (po-)flat $S$-posets
In this paper, we first consider (po-)torsion free and principally weakly (po-)flat $S$-posets, specifically we discuss when (po-)torsion freeness implies principal weak (po-)flatness. Furthermore, we give a counterexample to show that Theorem 3.22 of Shi is incorrect. Thereby we present a correct version of this theorem. Finally, we characterize pomonoids over which all cyclic $S$-posets are ...
متن کاملNCO-sP(EO-stat-PO) Coatings on Gold Sensors—a QCM Study of Hemocompatibility
The reliability of implantable blood sensors is often hampered by unspecific adsorption of plasma proteins and blood cells. This not only leads to a loss of sensor signal over time, but can also result in undesired host vs. graft reactions. Within this study we evaluated the hemocompatibility of isocyanate conjugated star shaped polytheylene oxide-polypropylene oxide co-polymers NCO-sP(EO-stat-...
