Formulation development of a novel antivirulence compound for enhanced pharmacokinetic properties
… magnitude of zeta potential that provides good electrostatic stabilization for at least 6 or 12 weeks depending on particle size and morphology when storing at 4 [degrees]C and room temperature. Both the small plate-like particles and the large curved-plate/tube-like particles, in the form of …

Characterization of the Central Cavity of a Potassium Channel: Helix Dipoles, Conformational Plasticity and Inhibition
… in the central cavity. It was proposed that some electrostatic stabilization for this potassium ion may come from the backbone of nearby α- helix C-termini, through the helix dipole effect. We studied the role of helix dipoles in KcsA using protein semisynthesis in order to modify the backbone of …

Influence of additives on stabilization and mineralization pathway of amorphous calcium carbonate nanoparticles
… acid) and Ca2+ on the mineralization and stabilization of PAA-ACC nanoparticles was investigated by measuring the size of the nanoparticles as a function of time using Dynamic Light Scattering (DLS); the adsorption of organic additives to PAA-ACC nanoparticles was investigated using Quartz …

Mechanistic and Structural Studies of Salicylate Biosynthesis in Pseudomonas aeruginosa
… reactions is controversial and may be arise from electrostatic stabilization of the transition state, or conformational stabilization of the reactive substrate. Structural and mutational studies on a key residue, lysine 42, of the active site loop suggest that rate enhancement of the two …

Influence of hydrophobically modified polyelectrolytes on nanoparticle synthesis in self-organized systems and in water
… be used as protecting agents. The reduction and stabilization of metal colloids in aqueous solution by adding self-synthesized hydrophobically modified polyelectrolytes were studied in much more details. The polymers used are hydrophobically modified derivatives of poly(sodium acrylate) and of …

Star-shaped Polyelectrolytes
… of the stars with increasing ionic strength. Electrostatic and osmotic screening leads to a retraction of the originally stretched arms, when no additional salt is present. However ion-specific effects lead to a more pronounced shrinkage when sodium chloride was exchanged with sodium iodide. …

In-situ steric stabilization of ultrafine titania particles synthesized by a sol-gel process
… measurements show the absence of any significant electrostatic stabilization effects under conditions giving the smallest particle sizes. In another related study, titanium dioxide particles were synthesized via the hydrolysis of tetraethylorthotitanate, TEOT, in mixtures of ethanol and …

Keramische Membranen auf Basis LPS-SiC: Schlickerentwicklung und Beschichtungsverfahren
Die Filtration unter aggressiven Einsatzbedingungen, z.B. Einsatz in korrosiven Medien, Abgasfiltration, stellt besondere Anforderungen an das Filtermaterial. Sogenanntes "Liquid Phase Sintered Silicon Carbide" (LPS-SiC) erfüllt die Anforderungen sehr gut. Deshalb bestand das Ziel der …
