Abstract: In accordance with the present invention, a method of prevention of defects in uniform coatings is proposed. The method comprises decelerating the advancement of the dewetting front of a coating attained by externally controlling the wettability and the size of a buffer zone at the boundary of the coating area. The surface of the buffer zone should have better wettability with respect to the fluid in the coating than the surface of the coating area.

Abstract: A temperature indicating cap shaped headwear device that is worn on a patient's head while the patient is having an injection-type of chemotherapy treatment. The headwear device has an outer layer of sheet material vertically spaced from an inner layer of sheet material. The outer layer is attached to the inner layer in a quilting pattern that forms individual cells between the outer layer and the inner layer of sheet material. Each of the quilting cells are filled with a temperature indicating material that can be brought to a substantially frozen state causing the material to exhibit a first color. As the material warms to a predetermined higher temperature outside the therapeutic range, the material changes to a second color which provides a visual signal that a new headwear device should be placed on the patients head if further chemotherapy treatment is required.
