چکیده

The thermodynamics of the bicomponent melts of linear chains A and unknotted unentangled closed chains B (trivial rings) is considered within the framework of i he usual Flory approach. It is shown that such melts exhibit a compatibility enhancement in comparison with the corresponding melts of linear chains. The reason for such effect is due to the topological entropy gain of mixing of Aand B-chains: if B-chains are unentangled since the A-chains play the role of a "diluent" softening the topological restrictions imposed on the B-chainsThis result is in agreement with recent experimental findings of McKnight et al.

Compatibility of B-Sheets with Epitopes Predicted by Immunoinformatic in Human IgG

Background & Aims: Antibodies, well-known as immunoglobulins (Igs), are produced by B lymphocytes and specifically defend against pathogens. Igs are glycoproteins and have high diagnostic value in several diseases including infections (1). Igs are composed of light and heavy chains (2, 3). Each chain is comprised of about 110-120 amino acid residues which create immunoglobulin folds named domai...

Stability of Self-Consolidating Concrete Containing Different Viscosity Modifiers

The main objective of this paper is to assess the effect of different viscosity-enhancing admixture (VEA) types and concentrations on deformability and stability of self-consolidating concrete (SCC). Two polysaccharide-based VEAs, one cellulose-based VEA, and a modified-startch VEA are used in this investigation. Regardless of polymer type, results showed that the incorporation of VEA leads to ...

Static scattering from cyclic copolymers in solution

The static scattering properties of cyclic diblock copolymers in solution are studied. The case of a symmetric diblock in a solvent satisfying the optical theta condition is considered in details. The results show substantial differences with respect to linear diblock copolymers. The additional entropic interaction in cyclic chains induces a decrease of the scattering intensity and a shift of t...

Dissolution Rate Enhancement of Clarithromycin Using Ternary Ground Mixtures: Nanocrystal Formation

Clarithromycin (CLA), a broad-spectrum macrolide, is a poorly soluble drug with dissolution rate limited absorption. The aim of this investigation was to prepare CLA nanoparticles from a ternary ground mixture in the presence of sodium lauryl sulfate (SLS) and polyvinyl pyrrolidone (PVP) as co-grinding water-soluble compounds, in order to improve the drug dissolution rate. Different weight rati...
