Abstract: Abrasion and scratch protective coatings magnetic coatings, electrically and thermally conducting coatings, and UV absorbing coatings are provided by electrostatic self-assembly (ESA) of one layer of an organic or polymer molecule and one layer of inorganic clusters in a layer by layer fashion at room temperature. A combination of inorganic clusters having a particle size of preferably less than 30 nm and flexible organic molecules allows fabrication of films tens to hundreds of micrometers thick, with large pores and excellent stress relaxation.

Abstract: A device, and a method for forming a softgel having multiple gelatin layers and softgels having multiple gelatin layers are disclosed. In particular there is provided a device for forming a gelatin sheet having at least two gelatin layers. Each gelatin layer has a thickness. The device comprises a gelatin spreader box which includes at least one opening for extruding a gelatin sheet. The device also includes a first and a second height adjustable gate disposed at least partially across the opening; and a first and a second height adjustment control. Adjustment of the first height adjustment control varies the height of the first gate and adjustment of the second height adjustment control varies the height of the second gate, thereby controlling the thickness of the at least two gelatin layers.
