Edge state magnetism in zigzag-interfaced graphene via spin susceptibility measurements.

Development of graphene spintronic devices relies on transforming it into a material with a spin order. Attempts to make graphene magnetic by introducing zigzag edge states have failed due to energetically unstable structure of torn zigzag edges. Here, we report on the formation of nanoridges, i.

[Generation of a nerve impulse as a process in plasma. II. Stability of volt-ampere characteristics of membrane contact].

Fluctuative changes of K+ ions concentration near the outward membrane surface are considered. Conditions of the excitement initiation on the membrane contact are determined from the solution of the unsteady-state diffusion equation. The values of the threshold potential and characteristic time of the nervous impulse development are obtained.

[Generation of a nerve impulse as a process in plasma. I. Volt-ampere characteristics of membrane contact].

A theory of the nervous impulse generation is proposed. It is based on the plasma (electrolyte) properties near the half-penetrated contact of the regions with different ions concentration. The main processes considered in this theory are following: a change of K+ ions concentration and diffusion of these ions near the outward membrane surface.
