Spectroscopic ellipsometry was used to examine the adsorption of poly͑ethylene glycol͒ ͑PEG͒ and Cl − on polycrystalline Cu, Ag, and Au electrodes in sulfuric acid. In halide-free sulfuric acid, PEG adsorption on Cu and Ag is minimal at potentials positive of the estimated potential of zero charge ͑pzc͒. PEG adsorption on Au was also negligible in halide-free environments positive of the pzc, but slight adsorption was evident near the pzc. In contrast, in the presence of adsorbed halide, PEG coadsorption is clearly evident at potentials near or positive of the pzc for all metal samples studied. The PEG/Cl − coadsorbed film does not provide a significant barrier to outer-sphere electron-transfer reactions ͓i.e., Ru 3+/2+ ͑NH 3 ͒ 6 ͔, although inner-sphere reactions associated with electrodeposition of copper are effectively inhibited. The implications of these observations with respect to the role of Cu + ions in the PEG-induced inhibition of Cu electrodeposition is discussed.

Photoemission electron microscopy (PEEM) is a unique surface-sensitive instrument capable of providing real-time images with high spatial resolution. While similar to the more common electron microscopies, scanning electron microscopy and transmission electron microscopy, the imaging technology relies on the photogeneration of electrons emitted from a sample through light excitation. This imaging technique has found prominence in surface and materials sciences, being well suited for imaging flat surfaces, and changes that occur to that surface as various parameters are changed (e.g. temperature, exposure to reactive gases). Biologically focused PEEM received significant attention in the 1970s, but was not aggressively advanced since that pioneering work. PEEM is capable of providing important insights into biological systems that extend beyond simple imaging. In this article, we identify and establish important issues that affect the acquisition and analysis of biological samples with PEEM. We will briefly review the biological impact and importance of PEEM with respect to our work. The article also concludes with a discussion of some of the current challenges that must be addressed to enable PEEM to achieve its maximum potential with biological samples.

“…Although, other factors responsible for the enhancement of the Raman signal (the so-called 'chemical' or charge transfer enhancement) have been added to the picture beginning with the paper by Albrecht and Creighton [34], and later dwelled upon by Otto [35], the plasmon-resonance mediated enhancement remains central for SERS. In 1980s, interest to plasmons in electrochemistry beyond SERS coincided with development of electromodulation spectroscopy [36,37] The boom in nanotechnology and nanoscience of this century gave rise to the second birth of plasmonics, more generally photonics (the science that including plasmonics as a particular case). Indeed, conventional materials derive their optical properties from atoms and molecules.…”
