<![CDATA[ NANO MURI Research Productivity of the Principal Investigators The principal investigators have been exceptionally productive researchers producing (according to the 1997 ACS Directory of Graduate Research) 451 publications over a time period approximating that of this grant. A breakdown of publications and students graduated (in parentheses) by investigator is given below: Dalton 38 (5) Olah 67 (2) Frechet 78 (3) Grubbs 47 (3) Prakash 67 (1) Prasad 66 (3) Hogen-Esch 32 (6) Gorman 12 (0) Weber 24 (6) Thompson 20 (2) This record of productivity would compare favorably with the research productivities of the largest and best science (chemistry, physics, engineering) departments in the nations. The fact that the Center personnel are truly extraordinary is also evidenced by the number of prestigious awards and appointments. A similar argument could be made for the junior personnel as reflected both by publications and by number of ACS & MRS awards. Each investigator has produced between 4 and 11 publications per year acknowledging Center support. Given the difficulty of the projects involved, this is truly exceptional productivity. With subsequent years of this Center grant, number of publications per investigator should increase dramatically. ]]>
