Bates and Barron -- SHERO Pad (IMAGE) University of Utah Caption University of Utah materials science and engineering student Amber Barron (left) and materials science and engineering assistant professor (lecturer) Jeff Bates are part of a team that has developed a new, 100-percent biodegradable feminine maxi pad that is made of all natural materials and is much thinner and more comfortable than other similar products. In front of them is a series of materials they have experimented with, including cotton, to make the finished maxi pad (far left on the table).
