The substrate is then rotated at speeds up to 10,000 rpm to spread the coating material by centrifugal force. A machine used for spin coating is called a spin coater, or simply spinner. [1] Rotation is continued while the fluid spins off the edges of the substrate, until the desired thickness of the film is achieved.
Slot-die coating is a non-contact coating method, in which the slot-die is typically held over the substrate at a height several times higher than the target wet film thickness. [23] The coating fluid transfers from the slot-die to the substrate via a fluid bridge that spans the air gap between the slot-die lips and substrate surface.
This allows creating thin films of various molecules such as nanoparticles, polymers and lipids with controlled particle packing density and layer thickness. [6] Spin coating or spin casting, uses a liquid precursor, or sol-gel precursor deposited onto a smooth, flat substrate which is subsequently spun at a high velocity to centrifugally ...
The French rape trial that shocked the world and sparked widespread calls for justice for women rape victims ended on Thursday with the conviction of 51 men for raping and attempting to rape ...
Spin casting, also known as centrifugal rubber mold casting (CRMC), is a method of utilizing inertia to produce castings from a rubber mold. Typically, a disc-shaped mold is spun along its central axis at a set speed.

The U.S. Fish and Wildlife Service is pushing for added protections for the monarch butterfly after suggesting multiple populations could go extinct in mere decades.
They also get really huffy around shiny things — things like windows or even cars. This behavior mostly happens during breeding season. Turkeys will peck, follow, or try and intimidate people ...
