A01_TRO1337_05_SE_FM.indd 22/09/14 3:25 PM To Annie About the Author Nivaldo Tro, is a Professor of Chemistry at Westmont College in Santa Barbara, California, where he has been a faculty member since 1990 He received his Ph.D in chemistry from Stanford University for work on developing and using optical techniques to study the adsorption and desorption of molecules to and from surfaces in ultra high vacuum He then went on to the University of California at Berkeley, where he did post doctoral research on ultrafast reaction dynamics in solution Since coming to Westmont, Professor Tro has been awarded grants from the American Chemical Society Petroleum Research Fund, from Research Corporation, and from the National Science Foundation to study the dynamics of various processes occurring in thin adlayer films adsorbed on dielectric surfaces He has been honored as Westmont's outstanding teacher of the year three times and has also received the college's outstanding researcher of the year award Professor Tro lives in Santa Barbara with his wife, Ann, and their four children, Michael, Ali, Kyle, and Kaden In his leisure time, Professor Tro enjoys mountain biking, surfing, reading to his children, and being outdoors with his family 5 A01_TRO1337_05_SE_FM.indd 22/09/14 3:25 PM Brief Contents Preface The Chemical World Measurement and Problem Solving Matter and Energy Atoms and Elements
