The cell membrane. It's called a bi-layer, and contains two layers of phospholipids. The tails interact with one another while the heads interact with the aqueous solution.

Phospholipid Bilayer
A double layered fluid structure containing sort of loose but contained things such as proteins, cholesterol molecules, etc. It has a hydrophobic layer of longer apolar lipid chains sandwiched in between two hydrophilic (polar) lipid edges.
The double layered sheet that makes up nearly all cell membranes is called a lipid bilayer. This structure is composed of phospholipid molecules, with hydrophilic heads facing outward and hydrophobic tails facing inward to form a barrier around the cell.
The double-layered membrane surrounding the nucleus is called the nuclear envelope. It has pores called nuclear pores which allow the movement of molecules like RNA and proteins in and out of the nucleus while regulating the passage of larger molecules. This structure helps to protect and regulate the contents of the nucleus.
Pleura is a double layered membrane surrounding each lung.
Hydrophobic molecules can cross the cell membrane because the membrane is made up of a double layer of lipids, which are also hydrophobic. This allows hydrophobic molecules to pass through the membrane easily, while hydrophilic molecules have a harder time crossing.

Layered double hydroxides (LDHs) were first discovered by Hans Fischer in 1942. Fischer observed the formation of these layered compounds during the hydrolysis of magnesium aluminum hydrotalcite.
The cell membrane is a complicated structure layered rather like a sandwich. The two pieces of bread are the lipid bilayers (bilayers as in the two pieces), the meats and cheeses is the hydrophobic region, and proteins are like the toothpick that is sticking out of the sandwich (there are multiple) and there are various carbohydrate chains coming off of the proteins, like the plastic wrapper on the top of the toothpick.
