Hierarchical self-assembly offers elegant and energy-efficient bottom-up strategies for the structuring of complex materials. For block copolymers, last decade witnessed great progress in diversifying structural complexity solution-based assemblies into multicompartment micelles. However, a general understanding what governs micelle morphologies polydispersity, how to manipulate their hierarchical superstructures using straightforward concepts readily accessible polymers remains unreached....

We investigated the thermoresponsive behavior of aqueous solutions star-shaped and linear poly(N,N-dimethylaminoethyl methacrylate) (PDMAEMA). The observed cloud points strongly decrease with increasing pH solution. This is explained by a weak charging star polymers decreasing pH. A significant molecular weight for high pH, i.e., almost uncharged state, was found to be virtually independent arm number length. These findings are classical Flory−Huggins theory. increase upon captured...

A self-consistent field analytical theory is developed to analyze the equilibrium structure of weakly charged polyelectrolyte brushes in salt-free solutions. In contrast previous studies based on local electroneutrality approximation valid for sufficiently strongly or densely grafted (“osmotic”) brushes, we consider a general case comprising both limits and systems without any priori assumptions about distribution counterions. The expressions various structural properties free confined are...
The thermodynamics and the driving forces of adsorption beta-lactoglobulin on spherical polyelectrolyte brushes (SPB) are investigated by isothermal titration calorimetry (ITC). SPB consist a polystyrene core onto which long chains poly(styrene sulfonate) grafted. Adsorption isotherms obtained from measurements ITC. analysis ITC shows clearly that process is solely driven entropy while DeltaH > 0. This finding in accordance with proposed mechanism counterion release: Patches positive charges...
Abstract Block copolymers self-assemble into a variety of nanostructures that are relevant for science and technology. While the assembly diblock is largely understood, predicting solution triblock terpolymers remains challenging due to complex interplay block/block block/solvent interactions. Here we provide guidelines self-assembly linear ABC large multicompartment with C corona A/B cores. The ratio block lengths N / A thereby controls micelle geometry spheres, cylinders, bilayer sheets...
Suppressor of cytokine signalling 1 (SOCS1) insufficiency is an inborn error immunity affecting the negative regulation and growth factor signalling. We aimed to enhance understanding clinical manifestations, disease trajectories, penetrance, effect Janus kinase (JAK) inhibition in individuals with SOCS1 insufficiency. This study used data from two independent cohorts: European Society for Immunodeficiencies (ESID) registry UK Biobank. Participants ESID were nine countries (Austria, Belgium,...
We have developed an analytical self-consistent-field (SCF) theory describing conformations of weakly charged polyelectrolyte chains tethered to the solid−liquid interface and immersed in a solution low molecular weight salt. Depending on density grafting polyelectrolytes salt concentration we distinguish three main asymptotic regimes behavior grafted layer. These are characterized by (i) unscreened Coulomb repulsion between polyions, (ii) screening interchain interactions predominantly...
We consider the interaction of multivalent counterions with spherical polyelectrolyte brushes (SPB). The SPB result if linear (PE) chains (contour length: 60 nm) are densely grafted to colloidal spheres 116 nm in diameter. Dispersed water, surface layer consisting strong PE poly(styrene sulfonic acid) (PSS) will swell. demonstrate that successive addition trivalent ions (${\mathrm{La}}^{3+}$) leads a collapse which is shrinking drastically. All findings discussed on base theoretical...
The theory describing chain conformation in a planar layer of grafted polyelectrolyte (polyampholyte) molecules and the conformational transition related to collapse this caused by decrease solvent strenght is developed. Depending on values parameters (grafting charge densities) may occur as continuous (cooperative) or first order phase transition.
