The C, N, and O K-edge near-edge X-ray absorption fine structure spectra of the 22 most common proteinogenic alpha-amino acids in the zwitterionic form collected from solvent-free polycrystalline… Expand
Soft X-ray Induced Decomposition of Phenylalanine and Tyrosine: A Comparative Study
The pristine state and soft X-ray induced decomposition of two aromatic amino acids, viz. phenylalanine and tyrosine, have been studied by means of XPS and NEXAFS. The spectroscopic data on the… Expand
Structure of thioaromatic self-assembled monolayers on gold and silver
Self-assembled monolayers (SAMs) formed from thiophenol, 1,1‘-biphenyl-4-thiol, 1,1‘;4‘,1‘ ‘-terphenyl-4-thiol, and anthracene-2-thiol on polycrystalline Au and Ag were characterized by X-ray… Expand
Characterization of X-ray Induced Damage in Alkanethiolate Monolayers by High-Resolution Photoelectron Spectroscopy
Synchrotron-based high-resolution X-ray photoelectron spectroscopy was for the first time applied to investigate the damage in self-assembled monolayers (SAMs) of alkanethiols (AT) on Au caused by… Expand
Odd−even effects at the S-metal interface and in the aromatic matrix of biphenyl-substituted alkanethiol self-assembled monolayers
Synchrotron-based high-resolution X-ray photoelectron spectroscopy was applied to characterize self-assembled monolayers (SAM) of biphenyl-substituted alkanethiols CH3(C6H4)2(CH2)nSH (BPn, n = 1−4)… Expand
Charge Transfer Time in Alkanethiolate Self-Assembled Monolayers via Resonant Auger Electron Spectroscopy
The dynamics of the charge transfer (CT) in alkanethiolate self-assembled monolayers is addressed by resonant Auger spectroscopy using the core hole clock method. The CT pathway was unambiguously… Expand
Light-powered electrical switch based on cargo-lifting azobenzene monolayers.
Inspired by the complex molecular machines found in nature, chemists have developed much simpler molecular motors. Among them, several systems incorporating azobenzene have been proposed, which… Expand

- 16 January 2008
High-resolution x-ray absorption and emission spectra of liquid water exhibit a strong isotope effect. Further, the emission spectra show a splitting of the 1b1 emission line, a weak temperature… Expand
Electron-induced crosslinking of aromatic self-assembled monolayers: Negative resists for nanolithography
We have explored the interaction of self-assembled monolayers of 1,1′-biphenyl-4-thiol (BPT) with low energy electrons. X-ray photoelectron, infrared, and near edge x-ray absorption fine structure… Expand
On the Importance of the Headgroup Substrate Bond in Thiol Monolayers: A Study of Biphenyl-Based Thiols on Gold and Silver
Self-assembled monolayers of a series of ω-(4‘-methyl-biphenyl-4-yl)-alkanethiols (CH3−C6H4−C6H4−(CH2)m−SH, m = 1−6) formed on polycrystalline gold and silver surfaces were characterized in detail by… Expand
