Novel assembled films of monolayer-protected clusters (MPCs) can be grown on gold and glass substrates with a 20-fold higher efficiency than established procedures. Thick MPC films grown using this new method, which can easily be scaled up or automated, are extremely stable and have properties identical to traditionally formed nanoparticle films, including unique quantized double layer charging effects. This new procedure for growing nanoparticle films shares the versatility of the traditional method but exhibits accelerated growth attributed to highly efficient sorption and mobility of metal ion linkers within swelled films and improved mass transfer of nanoparticles to assembly sites. Concentration …
Nondipole Effects In The Photoionization Of Xe 4d5/2 And 4d3/2: Evidence For Quadrupole Satellites, Oliver Hemmers, Renaud Guillemin, D. Rolles, A. Wolska, Dennis W. Lindle, K. T. Cheng, W. R. Johnson, H. L. Zhou, S. T. Manson

Measurements of nondipole parameters in spin-orbit-resolved Xe 4d photoionization demonstrate dynamical differences arising from relativistic effects. The experimental data do not agree with relativistic random-phase approximation calculations of single ionization dipole and quadrupole channels. It is suggested that the discrepancy is due to the omission of multiple-excitation quadrupole channels, i.e., quadrupole satellite transitions.

A new phenomenon sensitive only to next-door-neighbor atoms in isolated molecules is demonstrated using angle-resolved photoemission of site-selective core electrons. Evidence for this interatomic core-to-core electron interaction is observable only by measuring nondipolar angular distributions of photoelectrons. In essence, the phenomenon acts as a very fine atomic-scale sensor of nearest-neighbor elemental identity.
Self-Assembly Of Inorganic Membranes: Attachment Of Gold Nanoparticles To A Mesoporous Silica Membrane, Jennifer K. Saucier
Self-Assembly Of Inorganic Membranes: Attachment Of Gold Nanoparticles To A Mesoporous Silica Membrane, Jennifer K. Saucier
Honors College
The purpose of this study was to investigate the self-assembly of gold nanoparticles to create thin, densely packed structures several monolayers thick for the synthesis of a membrane. Silica membrane synthesis was examined as a support for deposition of the nanoparticles. Pore size formation and thickness were controlled to promote high flux, defect free layer formation while providing for optimum separation. Silica mesoporous membranes were created through the acid-catalyzed hydrolysis of tetraethyl orthosilicate. An ionic block co-polymer was used to control a networked pore formation. The silica sols were dip coated on macroporous alumina supports. The silica membranes were characterized …
