• Jacob N. Israelachvili, "Intermolecular and Surface Forces," 3rd ed. Academic Press, 2011 (recommended) (abbr: JNI)
• Pierre-Gilles de Gennes, Francoise Brochart-Wyart, David Quere."Capillarity and Wetting Phenomena," Spinger 2005 (translation from French, excellent but limited in scope to wetting phenomena) (abbr: PGdG)
• Johannes Lyklema, "Fundamentals of Interface and Colloid Science, Vol. 1 - 5." Academic Press, (useful as reference monographs, extensive coverage, but expensive) (abbr: JLvX)
• Handouts will be available for download from: http://afm1.pharm.utah.edu/PNSCourse/index.html
• The course notes follow the textbook; with additional material included as indicated.

Here is some small print:
General Policy: All examinations and assignments must be completed in accordance with the University of Utah Student Code. Materials disclosed to the instructor for evaluation must be the original work of the student. Use of material (such as equations, text or graphics) from the web or any other source without proper citation will be considered academic dishonesty.
Homework Policy: Four homework assignments will be required. Each homework will be posted on-line on Tuesdays and will be due one week later before class time. Students are expected to have working knowledge of a mathematical package such as Mathematica, Maple, Matlab or IgorPro and to complete their homework assignments using computer. Presentation in addition to technical content will constitute part of the grade. Late homework generally will not be accepted since solutions will be posted shortly after the due date/time.
