Stability of human serum albumin structure upon toxin uptake explored by small angle neutron scattering
Possible denaturation or tertiary structural changes of the protein human serum albumin (HSA) upon adsorption of uremic toxin is investigated using small-angle neutron scattering (SANS). Calorimetric data in previous studies give proof of the binding between HSA and two classes of uremic toxins: i) small molecular weight and ii) middle molecular weight molecules [...]

Swelling of a Responsive Network within Different Constraints in Multi-Thermosensitive Microgels
We report on the swelling of a polymeric network in doubly thermoresponsive microgels. Silica-core double-shell and hollow double-shell microgels made of an inner poly(N-isopropylmethacrylamide) and an outer poly(N-isopropylacrylamide) shell are studied by exploiting the distinct temperature sensitivities of the polymers.

Facially Amphipathic Glycopolymers Inhibit Ice Recrystallization
Antifreeze glycoproteins (AFGPs) from polar fish are the most potent ice recrystallization (growth) inhibitors known, and synthetic mimics are required for low-temperature applications such as cell cryopreservation. Here we introduce facially amphipathic glycopolymers that mimic the three-dimensional structure of AFGPs. [...]

Structural Analysis of Aluminum Oxyhydroxide Aerogel by Small Angle X-Ray Scattering
The work presents studies on the microstructure and mesostructure of nanostructured aluminum oxyhydroxide formed as a high porous monolithic material through the surface oxidation of aluminum liquidmetal solution in mercury in a temperature- and humidity-controlled air atmosphere. The methods of X-ray diffraction analysis, thermal analysis, the low temperature adsorption of nitrogen vapors, transmission electron microscopy, small-angle and very small-angle neutron scattering, and small-angle X-ray scattering are used for comprehensive investigation of the samples synthesized at 25°С as well as that annealed at temperatures up to 1150°C.

Formation of complexes in aqueous solutions of amphiphilic triblock polyelectrolytes of different topologies and an oppositely charged protein
Soft matter 14(15), 2860 - 2869 (2018) [10.1039/C8SM00208H]
The complexation of lysozyme with aggregates from two triblock amphiphilic polyelectrolytes of the same blocks but different topologies and block molar masses, namely PS-b-SCPI-b-PEO and SCPI-b-PS-b-PEO, is investigated by scattering and spectroscopy methods. Light scattering reveals that the interaction with lysozyme causes shrinkage of the self-assembled nanoparticles in the case of the hydrophobic–polyelectrolyte–hydrophilic sequence. [...]

Capillary condensation and gelling of microemulsions with clay additives
The capillary condensation in bicontinuous microemulsions takes place when two parallel surfaces are narrowed that result in a completely lamellar microemulsion. We expected that this phase transition is also observable when the amount of hydrophilic surfaces from clay particles is raised, because hydrophilic surfaces induce lamellar ordering locally. [...]

Spin Solid versus Magnetic Charge Ordered State in Artificial Honeycomb Lattice of Connected Elements
The nature of magnetic correlation at low temperature in two‐dimensional artificial magnetic honeycomb lattice is a strongly debated issue. While theoretical researches suggest that the system will develop a novel zero entropy spin solid state as T → 0 K, a confirmation to this effect in artificial honeycomb lattice of connected elements is lacking [...]

Swelling Behavior of Composite Systems: Mutual Effects between Polyelectrolyte Brushes and Multilayers
The combination of polyelectrolyte multilayers (PEMs) and end-grafted brushes represents a valuable approach to the design of complex organic composite materials with tailored responsive properties. This article addresses the correlation between the swelling properties of composites and their internal structure. [...]
