This book was released on 2022-10-13 with total page 520 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book addresses the application of Raman spectroscopic techniques to a range of diverse problems which arise in the study, conservation and restoration of artefacts and sites closely related to our cultural heritage as well as in authentication. These themes are naturally wider than what at first might be considered as artworks and archaeological artefacts and the topics include pigments, paintings, ceramics, glass, sculpture and patination / corrosion, textiles, industrial archaeology, the degradation and preservation of biomaterials, mummies and human skeletal remains. An interesting feature is the inclusion of modern case studies which describe specific problems and approaches to the Raman spectral analysis of items important to our cultural heritage. The text is prefaced with an introduction to the important parameters used in nondestructive Raman measurements and also highlights some future applications based upon novel miniaturised instrumentation for in-field studies and potential screening work which will identify specimens which would repay further studies in the laboratory. An attempt is made to give a snapshot of the state-of-the-art evolution since the beginning of the technique (1970s) and to point out potential further development. The book is co-edited by three international experts with many years' experience in the application of Raman spectroscopy to artworks, archaeological artefacts and in the investigation of materials and sites for cultural heritage preservation and each editor has undertaken to write individual chapters and different topics personally. The adopted approach is designed to convey the sort of information which has become available from the adoption of analytical Raman spectroscopy to different problems in the field of cultural heritage preservation through the spectral interrogation of artefacts and how the interpretation of the spectral data can assist museum curators, archaeologists and cultural heritage historians in the preservation and conservation of ancient materials and sites : a particular advantage in this respect is the ability of Raman spectroscopy to determine –generally in a strictly noninvasive procedure - at the laboratory or on-site with mobile instruments, the presence of both organic and inorganic components in a particular specimen together nondestructively without any chemical and mechanical pretreatment being undertaken, which is an essential requirement for rare and valuable samples . An important aside from this work is the means of spectral identification of ongoing biodeterioration and biological colonisation in specimens in storage and the effects of environmental deterioration such as humidity and temperature upon their integrity.

Download or read book FT Raman Spectroscopy of Keratins written by Waheed Akhtar and published by . This book was released on 1995 with total page 129 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the current work biological samples, taken from different mammalian and avian keratotic biopolymers, were examined using vibrational Raman spectroscopic and microscopic techniques. This was a continuation of earlier work reported in the literature on keratin tissues using FT-Raman spectroscopy with further investigation of previously unexamined samples, namely, cat's fur and claws, human nail, a pheasant's beak, and untreated, treated, and root samples of human hair. Assignments consistent with the FT-Raman vibrational wavenumbers were made to characterize the molecular and conformational nature of the samples, taking into account assignments made in previous studies. The keratin tissues studied showed several common bands in their spectra, demonstrating the similarities in their molecular conformation, but a number of structurally important differences were observed. The most important of these were the amide I and III bands; the assignments depend upon whether the samples studied existed in the alpha-helix conformation (nail, horn), or the beta-sheet structures (quill, beak), and in the sulphur content of tissues containing hard keratin (hair, nail) and soft keratin (callus tissue).

Among the topics covered are studies of drugs and their complexes with biomolecules on nanoparticles, application of SERS to blood analysis, studies of single cells and of applications to human cancer diagnostics.This will be a useful book for experimental scientists in academic, governmental, industrial and clinical environments and for those entering the field of biomolecular spectroscopy.

Download or read book Raman Spectroscopy Volume I written by Günter G. Hoffmann and published by Momentum Press. This book was released on 2019-01-16 with total page 251 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book provides an up-to-date overview of the fast growing area of Raman spectroscopy. The two-volume work describes how analytic methods using Raman spectroscopy allow for the chemical analysis of materials, providing even spatial resolution without precedent. In addition, external perturbations (strain, temperature, pressure) on molecules and their alignment can be analyzed. Raman spectroscopy can also provide information about the interactions of components, again at a high level of spatial resolution. In the form of tip-enhanced Raman spectroscopy (TERS), the method is a valuable tool for nanotechnology. This book is intended for researchers or lecturers in chemistry and materials science, who are interested in the composition and properties of their samples. It describes how Raman spectroscopy will enable them to examine thin layers, surfaces, and interfaces and improve their knowledge about the properties of composites. In addition, it can serve as a short introduction to vibrational spectroscopy.

This book was released on 2010 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Raman spectroscopy has been used to characterise both organic and geological samples in order to build a database for the future characterization of biomarker molecules that are of astrobiological relevance. Characteristic geological features and hydrated minerals recently found on the surface of Mars by the NASA planetary rovers Spirit and Opportunity suggest that a possible biosphere could have once existed there. Analytical instrumentation protocols for the unequivocal detection of biomarkers in suitable geological matrices are critical for future unmanned explorations, including the forthcoming ESA ExoMars mission scheduled for 2018. Several geological features found on the surface of Mars by planetary rovers suggest that a possible extinct biosphere could exist based on similar sources of energy as occurred on Earth. For this reason, analytical instrumental protocols for the detection of isolated biomarkers preserved in suitable geological matrices unequivocally and non-destructively have to be evaluated for future unmanned missions. Raman spectroscopy is currently part of the Pasteur instrumentation suite of the ExoMars mission for the remote detection of extant or extinct life signatures in the Martian surface and subsurface. Terrestrial analogues of Martian sites have been identified and the biogeological modifications resulting from extremophilic survival activity have been studied. Here we present the Raman spectral characterization of several examples of organic compounds which have been recorded using 785 nm, 633 nm and 514 nm laser excitation -polycyclic aromatic hydrocarbons (PAHs), organic acids, chlorophyll and carotenoids. Experimental mixtures of ß-carotene in usnic acid, PAHs in usnic acid and PAHs in mineral matrices have also been investigated. Organic compounds and PAHs located under crystalline minerals samples were identified using a 5x objective lens and 785 nm III excitation. The pure compounds and compound mixtures were also analysed using X-ray powder diffraction and scanning electron microscopy (SEM). The results of this study indicate that near infrared laser at 785 nm provided the clearest and the most informative spectra due to the reduction of fluorescence emission. Higher energy lasers operating in the visible region have resulted in the emission of significant background fluorescence. Few samples fluoresce even with the use of 785 nm excitation and FT-Raman spectroscopy remains the instrument of choice for the analysis of these samples.
