Pollen drift the distance it can travel and via what methods, and how to plant their fields to avoid unwanted cross-pollination. Corn pollen is particularly prone to pollen drift. Corn plants release their pollen for around a week, and an entire field may take up to two weeks to completely release its pollen; pollen release usually shows a spike two to three days after half the plants have released their pollen. Each individual plant can produce 4 to 5 million individual pollen grains. Its pollen is among the largest particles that can be found in the air, and is spherical in its
Spin coating Spin coating Spin coating is a procedure used to deposit uniform thin films to flat substrates. Usually a small amount of coating material is applied on the center of the substrate, which is either spinning at low speed or not spinning at all. The substrate is then rotated at high speed in order to spread the coating material by centrifugal force. A machine used for spin coating is called a spin coater, or simply spinner. Rotation is continued while the fluid spins off the edges of the substrate, until the desired thickness of the film is achieved. The applied solvent
