Pores in single crystalline semiconductors come in many forms (e.g., pore sizes from 2 nm to > 10 μm; morphologies from perfect pore crystal to fractal) and exhibit many unique properties directly or as nanocompounds if the pores are filled. The various kinds of pores obtained in semiconductors like Ge, Si, III-V, and II-VI compound semiconductors are systematically reviewed, emphasizing macrop...

A fundamental variable characterizing immiscible two-phase flow in porous media is the wetting saturation, which ratio between pore volume filled with fluid and total volume. More generally, this comes from a specific choice of coordinates on some underlying space, domain variables that can be used to express volumetric rate. The mathematical structure allows for introduction other containing s...

I consider a great lipid vesicle filled with an aqueous solution of a solute, for which its membrane is impermeable. Because of the mechanical tension induced by the osmotic flow, the vesicle swells up to a critical size, triggering a transient lipidic pore when it is introduced into a hypotonic aqueous medium. In this paper, we will obtain the differential equations of the vesicle dynamics, wh...

I discuss the strong link between transmission line (TL) equation and TL circuit model for charging of an electrolyte-filled pore finite length. In particular, show how Robin Neumann boundary conditions to equation, proposed by others on physical grounds, also emerge in subject a stepwise potential. The relaxes with timescale $\ensuremath{\tau}$, expression which consistently follows from circu...

Abstract Synthesis of proton-conducting materials based on track-etched membranes from polyvinylidene fluoride and sulfonated cross-linked polystyrene is described. The synthesis has been carried out by filling the pores original or gamma-irradiated membrane copolymerization styrene/divinylbenzene followed sulfonation with chlorosulfonic acid. resulting have studied scanning electron microscopy...
