Cecil L. Brown Lectureship - North Jersey Section

The biennial Cecil L. Brown Lectureship was established by NJ-ACS in 1969 to bring a distinguished chemist to a local university in the North Jersey area. Past recipients of this lectureship include seven Nobel laureates as well as many other towering figures in chemistry.

This lectureship was named after Cecil L. Brown, who spent his entire professional career at Esso (which later became Exxon) and chaired NJ-ACS as well as the Petroleum Division of national ACS in the 1950s. He was also the Chairman of the Esso Research Contributions and Research Grants Committee. During his chairmanship some 400 grants were made to 60 colleges and universities. As an administrative member of the Esso Education Foundation, he helped carry out a special $1.5 million program for the improvement of science and engineering teaching in New Jersey. He was a strong a proponent of having world-class chemists visit and work with students. Through the Cecil L. Brown Lecture, it is fitting that his name continues to be associated with excellence in chemical education in our area.

Past Recipients

The 2011 Distinguished Lecturer is Professor Louis Brus, Institute Professor at Columbia University.

Professor Brus has a BA from Rice University and a PhD from Columbia University, both in Chemical Physics. As a Lieutenant in the U. S. Navy, he worked in the solid state and chemistry divisions of the Naval Research Laboratory in Washington DC. In 1973 he joined the research area of Bell Laboratories in Murray Hill, NJ, where he became Distinguished Member of Technical Staff. He returned to Columbia in 1996, where he is now S. L. Mitchill Professor of Chemistry. He is a member of the US National Academy of Sciences, and in 1998 was the Chairman of the Board of Trustees of the Gordon Conferences. He was originally trained in gas phase spectroscopy and kinetics. In the 1980s he explored basic ideas and colloidal methods for semiconductor nanocrystals (Qdots) that exhibit quantum size effects. His present interests include carbon nanotubes and graphene, chemical applications of local electromagnetic fields, and solar energy nanoscience. He has received the APS Langmuir Prize, the ACS Chemistry of Materials Prize, the OSA Wood Prize, the inaugural Kavli Prize in Nanoscience, and the NAS Prize in the Chemical Sciences.

Abstract: We explore the fundamental nature and dynamics of excited electronic states in graphitic carbon materials. In semiconducting carbon nanotubes, near-infrared two photon luminescence excitation spectra quantitatively reveal very-strongly-bound exciton excited states. Electron-electron interactions are compared among CdSe nanocrystals, graphene, and carbon nanotubes. The independent contributions of screening and dimensionality are analyzed. Electronic and vibrational degrees of freedom are significantly coupled in graphene. The metallic versus molecular nature of single sheet graphene is strongly affected by charge transfer doping by adsorbed molecular species. Asymmetric doping in bilayer graphene can open a band gap, as revealed by the Raman spectra. Optical absorption bleaching and Raman Fano lineshapes are observed in few layer graphenes very highly doped by adsorbed alkalis.

I am extremely pleased and honored to serve as the Chair of the North Jersey Local Section (NJ ACS) for 2025.   Before looking forward, I’d like to begin by congratulating our section on an incredibly successful year in 2024.
