First evidence and the mechanism of formation of closed bilayer structures by a single chain amino acid ionic liquid (IL), L-proline isopropylester laurylsulfate in both hydrophilic and hydrophobic ILs, is reported. Such ionic self-assemblies are shown to be guided by fine balance of solvophobic effects and ionic arrangements via hydrogen bonding and electrostatic interactions.

Controlled aggregation of perylene bisimides in multiple modes has been achieved via symmetric substitution with peptides. Using optical probes of aggregation, the balance of hydrophobic and electrostatic forces are found to play a key role in directing self assembly and are exploited via solvent, pH, and specific extrinsic ion effects.

Light-responsive artificial ion channels are created using self-organized TiO(2) nanotubular arrays, whose ion transport properties can be regulated by external ultraviolet light. The formation of electrostatic traps within TiO(2) nanotubes by UV light contributes to the light-regulated ion transport.

In this work, yolk-shell structured magnetic hollow mesoporous silica (MHMS) nanospheres with controllable magnetic responsibility, high specific surface area, a huge cavity and ink-bottle type mesopores were successfully synthesized in one-step by an electrostatic self-assembly templated approach. The obtained MHMS nanospheres exhibited low cytotoxicity, excellent biocompatibility and potentia...

A highly versatile soft gripper that can handle an unprecedented range of object types is developed based on a new design of dielectric elastomer actuators employing an interdigitated electrode geometry, simultaneously maximizing both electroadhesion and electrostatic actuation while incorporating self-sensing. The multifunctionality of the actuator leads to a highly integrated, lightweight, fa...

The widespread occurrence of protein channels offers a good opportunity to fabricate protein architectures. Herein, we have developed a novel strategy for linear self-assembly of ferritin cages induced by poly(α, L-lysine) through channel-directed electrostatic interactions at pH 7.0. The length of the formed filaments can be controlled.

We study the classical and quantum motion of a relativistic charged particle on the spacetime produced by a global monopole. The self-potential , which is present in this spacetime, is considered as an external electrostatic potential. We obtain classical orbits and quantum states for a spin-1/2 and spin-0 particles.
