Ionic interactions offer the highest non-covalent cohesive strength in supramolecular assemblies. In spite of that, they have been consistently underestimated development self-healing materials due to their lack directionality and association specificity. this paper, ionic moieties are introduced as side-chain pendants poly(urea-urethane) siloxane-based polymers, aiming obtain a strong yet flex...

Organic electrochemical transistors (OECTs) utilize ion flow from the electrolyte to modulate electrical conductivity of whole bulk organic semiconductor channel. With characteristic mixed ionic-electronic conducting in entire volume, OECTs exhibit high transconductance and act as good transducers, particularly bioelectronics. To gain high-performance OECTs, developing novel polymeric semicondu...

Synthetic lysine polypeptides of high molecular weight (1) have been shown to reduce virus infectivity (2, 3), inhibit bacterial growth and respiration (4), agglutinate virus particles, bacterial cells, and erythrocytes (4-6), and to prolong blood clotting time (7). It has been suggested that most of these phenomena are associated with the formation of many ionic bonds between the positively ch...

Using small-angle X-ray scattering (SAXS), we have studied the initial stage (nucleation and oligomerization) of actin polymerization induced by raising temperature in a stepwise manner from 1°C to 30°C at low ionic strength (4.0 mg ml-1 actin in G-buffer). The SAXS experiments were started from the mono-disperse G-actin state, which was confirmed by comparing the scattering pattern in q- and r...

Polymerization of the intact capsid protein (CA) of HIV-1 into mature capsidlike particles at physiological ionic strength in vitro requires macromolecularly crowded conditions that approach those inside the virion, where the mature capsid is assembled in vivo. The capsid is organized as a hexameric lattice. CA subunits in each hexamer are connected through interfaces that involve the CA N-term...

Organic, solid-state batteries require efficient solid electrolytes able to provide stable ion conduction. Here, based on ionic liquid (IL) polymers with chloride counterions as electrolyte materials for are presented. Acrylic monomers imidazolium substituents alkyl side groups that linked by spacers the acrylic group employed. The IL either converted thermally initiated radical polymerization ...
