Evert Gorter and François Grendel (Dutch physiologists) approached the discovery of our present model of the plasma membrane structure as a lipid bi-layer. They simply hypothesized that if the plasma membrane is a bi-layer , then the surface area of the mono-layer of lipids measured would be double the surface area of the plasma membrane.
An outer membrane defines an inner region 1, which in turn surrounds level two membrane regions 2, 3 and 4. Region 4 has three deeper regions 5, 6 and 7, of which region 6 in turn has two deeper regions 8 and 9. Regions of the same depth share a color. The transport function at each membrane defines the overall logic of the membrane computer.

Fluid mosaic model of a cell membrane. The fluid mosaic model explains various characteristics regarding the structure of functional cell membranes.According to this biological model, there is a lipid bilayer (two molecules thick layer consisting primarily of amphipathic phospholipids) in which protein molecules are embedded.
The movement of phospholipids, even those located in the outer leaflet of the membrane, is regulated by the actin-based membrane skeleton meshwork.Which is surprising, because the membrane skeleton is located on the cytoplasmic surface of the plasma membrane, and cannot directly interact with the phospholipids located in the outer leaflet of the plasma membrane.
Unlike a vesicle or a cell membrane in which the lipid bilayer is rolled into an enclosed shell, a supported bilayer is a planar structure sitting on a solid support. Because of this, only the upper face of the bilayer is exposed to free solution. This layout has advantages and drawbacks related to the study of lipid bilayers.
3D Viewer (formerly Mixed Reality Viewer and before that, View 3D) [2] [3] [4] is a 3D computer graphics viewer and augmented reality application that was first included in Windows 10 1703. It supports the .fbx , .3mf , .obj , and .stl and many more file formats [ 5 ] listed in features section.
