“…The semi-steric stabilisation combines steric repulsion and the reduction of the Hamaker constant [19]. Hence, the dispersed particles do not possess sufficiently long molecule chains of the dispersant that are able to keep the particles apart from each other, but the reduction of the Hamaker constant can result in the reduction of the van der Waals force.…”

The production and optimisation of screen printing (SP) pastes containing La0.58Sr0.42Co0.21Fe0.79O3 – δ and La0.61Sr0.41Co0.19Fe0.79O3 – δ (LSCF) were investigated. The application of these nanopowders is supposed to improve the cathode's microstructure and increase its mechanical strength. Thirty seven pastes containing LSCF were carried out with variation in binders, dispersants and different particle size distribution. The rheological behaviour of these pastes was investigated. It was found that commercially available dispersant Solsperse 3000 resulted in the best suspension stability, achieving almost 55 times lower viscosity value for pastes containing 20 vol.‐%, than pastes without any dispersants. The shear thinning behaviour was found to be favourable for the LSCF cathode deposition. A cathode made from the mixture of nano and submicron powder exhibits a polarisation resistance as low as 0.76 Ω cm2 at 592 °C.

“…Knowledge of the composition and thickness of the adsorption layer at the S/L interface is essential for the description of not only adsorption but also other related phenomena such as the stability of disperse systems, the magnitude of forces operating between particles or surfaces, and the structure and rheological behavior of suspensions (4)(5)(6).…”

“…Lennard-Jones helices, in the following considered as continuous lines, have a cousin in the polymer model of Lennard-Jones chains [3,4]. The primary structure of Lennard-Jones Waals forces were calculated between colloidal particles of various simple geometric shapes [15,16] as well as for more complicated symmetries such as shells [17], tori [18] and helices [19]. The effect of charge on helicity has also been considered [20,21].…”

Abstract:Helical structures with Lennard-Jones self-interactions are studied for optimal conformations. For this purpose, their self-energy is analyzed for extrema with respect to the geometric parameters of the helices. It is found that Lennard-Jones helices exhibit a first order phase transition from a state with large curvature of the helical backbone to one with a small curvature. I.e. from a dense helix to an extended helix. A transition from one helical structure to another is a phenomenon known to take place in self-assembling helices formed in multicomponent solutions with cholesterol.
