Due to its polyionic character the DNA double helix is stable and biologically active only in salty aqueous media where its charge is compensated by solvent counterions. Monovalent metal ions are ubiquitous in DNA environment and they are usually considered as the possible driving force of sequence-dependent modulations of DNA structure that make it recognizable by proteins. In an effort to dir...

We report on a novel method to utilize genetically engineered M13 phages as functional nano building blocks that can form structurally aligned film and fiber matrices for tissue engineering scaffolds. Twoand three-dimensional directionally aligned long range ordered structures were constructed using shearing and polyionic complexation with cationic polymers. Further we have demonstrated that al...

the present investigation entails a procedure by which the surface tension and viscosity of liquids could be redicted.to this end, capillary experiments were performed for porous media by utilizing fifteen different liquids and powders. the time of capillary rise to a certain known height of each liquid in a particular powder was recorded. two artificial neural networks (anns) were designed and...

Abstract Cellulose–poly(ferrocenylsilane) (PFS) polyionic liquid (PIL) composite sponges are fabricated by codissolution of cellulose and PFS‐PIL, followed solvent exchange freeze‐drying. The hybrid used to in situ produce immobilize palladium nanoparticles (Pd NPs), leading Pd NP‐decorated porous supports. formation NPs is confirmed TEM XPS measurements. as‐prepared cellulose/PFS‐PIL@Pd exhibi...

Abstract In this study, the influence of direct electric current on a microcapsule was investigated. The consisted core from calcium ion and sodium alginate (SA) complex membrane formed by polyionic complexation poly(methylene-co-guanidine) (PMCG) cellulose sulfate (CS). Microcapsules showed swelling decreasing mechanical properties under applied current, anisotropic electrode side. effect is a...

We introduce an ultrasoft core model of interpenetrating polycations and polyanions, with continuous Gaussian charge distributions, to investigate polyelectrolyte aggregation in dilute and semi-dilute salt-free solutions. The model is studied by a combination of approximate theories (random phase approximation and hypernetted chain theory) and numerical simulations. The calculated pair structur...

Adjuvants improve the adaptive immune response to a vaccine antigen by modulating innate immunity or facilitating transport and presentation. The selection of an appropriate adjuvant has become vital as new vaccines trend toward narrower composition, expanded application, and improved safety. Functionally, adjuvants act directly or indirectly on antigen presenting cells (APCs) including dendrit...

wood vinegar is the aqueous phase of the liquid produced during the slow pyrolysis of wood.it has the potential to be used as a pesticide against various weeds, insects and molluscs. due to divergentfeedstocks, pyrolysis processes and storing conditions, the chemical composition of wood vinegar variesbetween producers and time. the aim of our current study was to use the copse snail arianta arb...
