Self-organization in nonlinear dynamical systems and its relation to the materials science

Potential oscillations induced by localized corrosion of the passivity on iron in halide-containing sulfuric acid media as a probe for a comparative study of the halide effect

“…Many recent studies are directed towards developing practical applications by exploiting self-organized structures arisen in both time and space. Such examples are widespread in the field of materials science [5]. For instance, electrochemical preparation of nanostructures [6][7][8][9][10], characterization of metal stability [11][12][13][14], generation of electrochemical biosensors [15][16][17], operation of proton exchange membrane fuel cells (PEMFCs) containing low levels of CO in anode feed [18][19][20][21], all exploit nonlinear reaction dynamics to control particular processes, develop diagnostics or achieve improved efficiencies.…”

Origin of finite pulse trains: Homoclinic snaking in excitable media

“…Examples include biological sys tems [4,5], autocatalytic chemical reactions [6,7], electro chemistry [8], liquid crystals [9], nonlinear optics [10], semi conductors [11][12][13], and pipe flow [14]. A spatially extended system with a stable spatially uniform equilibrium state is called excitable when a large enough, spatially localized perturbation excites adjacent sites while the perturbation at the original location decays back to equilibrium.…”

Synthesis and Self-Assembly of Chiral Cylindrical Molecular Complexes: Functional Heterogeneous Liquid-Solid Materials Formed by Helicene Oligomers

“…Heterogeneous liquid-solid materials can be constructed by self-assembly of materials derived from molecules [ 1 , 2 , 3 , 4 , 5 , 6 , 7 , 8 , 9 , 10 , 11 , 12 , 13 , 14 , 15 , 16 ]. Self-assembly involves the noncovalent bond formation, which has several advantages compared with the covalent bond formation: (1) Various shapes and structures of self-assembly materials can be formed by tuning the molecular structures; (2) diverse mechanisms of noncovalent bond formation can be used, including hydrogen-bonding, electrostatic interactions, van der Waals interactions, solvophobic interactions, π-π interactions and dipole-dipole interactions; (3) various spatial interactions including point-to-point, point-to-fiber, fiber-to-fiber, fiber-to-face and face-to-face modes are available, which are not restricted to the point-to-point interactions, that characterize covalent bond formation; (4) properties of the interactions can be affected largely by conditions such as temperature, concentration, light and chemical substances; (5) self-assembly materials can be degraded without using much energy and the constituent molecules may be recovered and reused.…”
