A minimal surface is one for which, like a soap film with the same pressure on each side, the mean curvature is zero and, thus, is one where the two principal curvatures are equal and opposite at every point. For every closed circuit in the surface, the area is a minimum. Schwarz1 and Neovius2 showed that elements of such surfaces could be put together to give surfaces periodic in three dimensions. These periodic minimal surfaces are geometrical invariants, as are the regular polyhedra, but the… 
Periodic Surfaces of Prescribed Mean Curvature
While there are eighteen triply periodic minimal surfaces that reportedly are free of self-intersections, to date there is no known example of a triply periodic surface of constant, nonzero mean
Films of Amphiphiles and Minimal Surfaces
A film of amphiphiles is made of two identical facing interfaces and its middle surface is a surface of symmetry. This symmetry leads the structures built by the film to be considered as
Micelles and Foams: 2-D Manifolds Arising from Local Interactions
Surfaces as 2-D manifolds play an important role in the description of structures, from inorganic materials to biological systems. These surfaces which can be planar, spherical or hyperbolic

TLDR
It is observed that multiply continuous structures are most easily generated close to the water-oil coexistence region, and the geometrical characteristics of these phases, such as genus per unit cell, surface area per unit volume, and volume fraction occupied by oil or water, are studied.
Scattering on triply periodic minimal surfaces—the effect of the topology, Debye-Waller, and molecular form factors
We compute scattering patterns for four triply periodic surfaces (TPS). Three minimal—Schwarz P (Im3m), Schwarz D—diamond (Pn3m), Schoen G—gyroid (Ia3d), and one nodal S1 (Ia3d). Simple
Topological Versus Physical and Chemical Properties of Negatively Curved Carbon Surfaces
Some relevant physical and chemical properties of negatively curved carbon surfaces like sp 2-bonded schwarzites can be predicted or accounted for on the basis of purely topological arguments. The
Periodic systems of frustrated fluid films and « bicontinuous » cubic structures in liquid crystals
We consider periodic organizations of two fluid media separated by interfaces in which interactions between the two media, normal to the interfaces, maintain constant distances between interfaces and

A special kind of three-periodic minimal surface has been studied, namely surfaces that are generated from disc-like-spanned skew polygons and that intersect themselves exclusively along straight
Infinite Periodic Minimal Surfaces: A Model for Blue Phases
Abstract The local constraint of double twist cannot lead to long range order in our physical space ℝ. Cubic blue phases can be interpreted as an array of disclination lines. The symmetry 1432, P4232
