id Fred J. Palensky, Ph.D., executive vice president, Research and Development and chief technology officer at 3M. "Her discoveries will influence and benefit society for decades. The financial impact of her work is enormous and far-reaching. To date, her research has resulted in commercialized products that have contributed nearly $2 billion to 3M's revenue."

ACS is honoring Cadotte and Mickols for developing the modern membranes used in the world's largest desalination method termed reverse osmosis (RO) for removing salt from seawater and brackish water so that it is fit for human consumption. In reverse osmosis, pumps force salt water through a membrane. Salt and other unwanted materials in the water can't pass through the membrane and stays behind in one tank, while fresh water collects on the other side of the membrane.

In the 1970s, Cadotte invented the FT-30 polymer and process for making it into a membrane. This is the polymer and process used by almost all of the world's current producers of RO membranes. Mickols later improved on that work. He invented high-efficiency FilmTecTM RO membranes that can treat up to five times more water per hour, with two to four times greater energy-efficiency and lower cost. Sales of these membranes from Dow Water & Process Solutions generated $320 million in revenues last year.

"Nine billion gallons of drinking water and industrial process water are being produced every day around the world with Dow technology," said William Banholzer, Ph.D., executive vice president and chief technology officer at Dow. "This technology has had great benefits to humanity. Supplies of clean fresh water are under enormous stress because of global population growth, environmental degradation, and climate change that is altering patterns of water availability in complex ways."

ACS is recognizing the Novartis team for discovering aliskiren (marketed as Tekturna and Rasilez), a new medication for high blood
