This book was released on 1988 with total page 9 pages. Available in PDF, EPUB and Kindle. Book excerpt: Surface enhanced Raman scattering has developed into an important spectroscopic tool in the identification of adsorbates on silver, copper, or gold under in situ conditions. This paper describes the first use of this technique to study the kinetics of surface enhanced catalyzed chemical reactions. The reaction of NO2 gas with Ag powder is shown to proceed through the formation of AgNO2 which autocatalytically decomposes into AgNO3, NO, and free Ag which forms Ag microstructures. Recent experiments to elucidate the reactions of DMMP at these catalytically active sites show that H2PO4 and HPO4 are formed on the surface at room temperature. The use of dynamically produced active Ag sites as active filters for phosphonates is discussed. Keywords: Surface Enhanced Raman Scattering (SERS), Phosphonates, Kinetics, Catalysis.

Available in PDF, EPUB and Kindle. Book excerpt: Surface enhanced Raman scattering (SERS), has the potential to be powerful tool in the study of surface chemical reaction processes. Sensitive to less than monolayer coverage even under ambient conditions, SERS has been used to obtain detailed surface reaction kinetics in only a few cases. The applications of SERS to study surface chemical reaction kinetics is presently limited because the enhancement mechanisms are reaction dependent. That is, the size and the number density of the surface roughness is dependent on the reaction parameters, such as delta H and temperature that are functions of time. For selected reactions, a partial solution exists if during the course of the reaction, surface reconstruction is confined to modification of the adatom structures. Electromagnetic enhancement, due to surface roughness of approx 20nm, is nearly constant in this case, and only the adatom enhancement mechanism is time dependent. The adatom concentration is also proportional to the background intensity due to electron-hole recombination in the metal substrate. Thus the adatom time dependence of the SERS spectra may be removed by normalization to the background in a spectral region without discrete SERS peaks. Applications to the decomposition of allynes, phosphonates, and NO2 on silver powders provide supportive evidence. Keywords: Reaction kinetics.

Available in PDF, EPUB and Kindle. Book excerpt: SERS was discovered in the 1970s and has since grown enormously in breadth, depth, and understanding. One of the major characteristics of SERS is its interdisciplinary nature: it lies at the boundary between physics, chemistry, colloid science, plasmonics, nanotechnology, and biology. By their very nature, it is impossible to find a textbook that will summarize the principles needed for SERS of these rather dissimilar and disconnected topics. Although a basic understanding of these topics is necessary for research projects in SERS with all its many aspects and applications, they are seldom touched upon as a coherent unit during most undergraduate studies in physics or chemistry. This book intends to fill this existing gap in the literature. It provides an overview of the underlying principles of SERS, from the fundamental understanding of the effect to its potential applications. It is aimed primarily at newcomers to the field, graduate students, researchers or scientists, attracted by the many applications of SERS and plasmonics or its basic science. The emphasis is on concepts and background material for SERS, such as Raman spectroscopy, the physics of plasmons, or colloid science, all of them introduced within the context of SERS, and from where the more specialized literature can be followed. Represents one of very few books fully dedicated to the topic of surface-enhanced Raman spectroscopy (SERS) Gives a comprehensive summary of the underlying physical concepts around SERS Provides a detailed analysis of plasmons and plasmonics

This book was released on 2018-12-05 with total page 167 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book explores the phenomenon of surface-enhanced Raman scattering (SERS), the huge amplification of Raman signal from molecules in the proximity of a metallic nanostructured surface, allowing readers to gain an in-depth understanding of the mechanisms affecting the spectroscopic response of SERS-active systems for effective applications. SERS spectroscopy is an ultrasensitive analytical technique with great potential for applications in the field of biophysics and nanomedicine. As examples, the author presents the design of nanocolloid-based SERS-active substrates for molecular sensing and of a folate-based SERS-active nanosensor capable of selectively interacting with cancer cells, enabling cancer diagnostics and therapy at the single-cell level. The author also suggests novel paths for the systematization of the SERS nanosystem design and experimental protocols to maximize sensitivity and reproducibility, which is essential when real-world biomedical applications are the goal of the study. With a combined approach, both fundamental and applied, and a detailed analysis of the state of the art, this book provides a valuable overview both for students new to SERS spectroscopy and for experts in the field.

Available in PDF, EPUB and Kindle. Book excerpt: In the course of the development of surface science, advances have been identified with the introduction of new diagnostic probes for analytical characterization of the adsorbates and microscopic structure of surfaces and interfaces. Among the most recently de veloped techniques, and one around which a storm of controversy has developed, is what has now been earmarked as surface enhanced Raman scattering (SERS). Within this phenomenon, molecules adsorbed onto metal surfaces under certain conditions exhibit an anomalously large interaction cross section for the Raman effect. This makes it possible to observe the detailed vibrational signature of the adsorbate in the ambient phase with an energy resolution much higher than that which is presently available in electron energy loss spectroscopy and when the surface is in contact with a much larger amount of material than that which can be tolerated in infrared absorption experiments. The ability to perform vibrational spectroscopy under these conditions would lead to a new understanding about the chemical identity, geome try, and bonding of adsorbed material at a level previously unacces sible. It is for these reasons that the last few years have brought an explosion of activity surrounding the exploitation of SERS. The search for the origines) of the anomalous enhancement has given rise to a research sub-activity of its own. Efforts to explain the en hancement have led to an increased understanding of the whole range of phenomena associated with the interaction of photons with adsor bates and metal surfaces.
