The series Topics in Current Chemistry Collections presents critical reviews from the journal Topics in Current Chemistry organized in topical volumes. The scope of coverage is all areas of chemical science including the interfaces with related disciplines such as biology, medicine and materials science. The goal of each thematic volume is to give the non-specialist reader, whether in academia or industry, a comprehensive insight into an area where new research is emerging which is of interest to a larger scientific audience.
Each review within the volume critically surveys one aspect of that topic and places it within the context of the volume as a whole. The most significant developments of the last 5 to 10 years are presented using selected examples to illustrate the principles discussed. The coverage is not intended to be an exhaustive summary of the field or include large quantities of data, but should rather be conceptual, concentrating on the methodological thinking that will allow the non-specialist reader to understand the information presented.
Contributions also offer an outlook on potential future developments in the field. In every review article, an up-to-date reference list gives the reader the opportunity for further, more specialist reading. The book is addressed to established scientists and graduate students, and in general to those who are responsible for research in the cultural heritage field.

The turn of the century was also a turning point in the history of chemistry. Consequently, a survey of the Nobel Prizes in Chemistry during this century will provide an analysis of important trends in the development of this branch of the Natural Sciences, and this is the aim of the present essay. Chemistry has a position in the center of the sciences, bordering onto physics, which provides its theoretical foundation, on one side, and onto biology on the other, living organisms being the most complex of all chemical systems.
Thus, the fact that chemistry flourished during the beginning of the 20th century is intimately connected with fundamental developments in physics. This is instead created by a cloud of electrons circling around the nucleus. Rutherford received the Nobel Prize for Chemistry already in for his work on radioactivity see Section 2. Niels Bohr from Copenhagen understood that an important clue to the solution of this problem could be found in the distinct lines observed in the spectra of atoms, the regularities of which had been discovered in by the physics professor Johannes Janne Rydberg at Lund University.
Consequently, Bohr formulated in an alternative atomic model, in which only certain circular orbits of the electrons are allowed. In this model light is emitted or absorbed , when an electron makes a transition from one orbit to another. Bohr received the Nobel Prize for Physics in for his work on the structure of atoms. Another step in the application of the electronic structure of atoms to chemistry was taken in , when Gilbert Newton Lewis suggested that strong covalent bonds between atoms involve a sharing of two electrons between these atoms electron-pair bond.
Lewis also contributed fundamental work in chemical thermodynamics, and his brilliant textbook, Thermodynamics , written together with Merle Randall, is counted as one of the masterworks in the chemical literature. Much to the surprise of the chemical community, Lewis never received a Nobel Prize. Fundamental work had, however, also been done in more traditional chemical fields, particularly in organic chemistry and in the chemistry of natural products, which is clearly reflected in the early prizes.

Inventing new chemical reactions is a long-standing passion of chemists, as reflected in the ever-popular field of reaction methodology. Historically, the environment in which newly crafted transformations would be performed imposed minimal limitations on reaction design; after all, solvents can be screened to find an optimal choice, temperature can be modulated, air and moisture can be excluded, catalysts can be added, competing functional groups can be protected, and byproducts can be siphoned away.
Such flexibility permitted the use of diverse reagents and conditions, culminating in a vast compendium of synthetic transformations that has been wielded to produce myriad complex chemical structures. The target-driven synthetic chemist now enjoys an impressive reaction toolkit. But what if the challenge were inverted, wherein the target structure was relatively simple but the environment in which the necessary reactions must proceed was so chemically complex and uncontrollable that no two functional groups could combine reliably and selectively under such conditions?
Bioorthogonal chemistry, the topic of this special issue of Accounts of Chemical Research , addresses precisely this challenge, with reaction environments of interest ranging in complexity from aqueous solutions of biomolecules to live animals. Dating back just over a decade, the field was launched alongside the growing realization that the molecular details of biological processes can be most accurately understood by probing biomolecules within their native habitats, that is, in cells, or even better, live organisms.
To interrogate biomolecules in such complex settings requires the means to selectively modify them with imaging probes, affinity reagents, or moieties that perturb function. In earlier decades, biology-derived technologies such as monoclonal antibodies and genetic fluorescent protein fusions enabled great strides toward elucidating the roles of specific proteins in dynamic cellular processes. Though their target selectivity is exquisite, even within environs as complex as laboratory animals, these biological tools were not amenable to every protein type; the large size of fluorescent proteins imposes too significant a structural perturbation for many targets, and antibodies are excluded from the intracellular space.
Nor were antibodies and fluorescent protein fusions readily translated to nonprotein biomolecules.

Archaeological chemistry belongs to the broader research field of archaeometry, which represents the application of various scientific analytical techniques to archaeological artefacts. These can include physics, chemistry, biology, palaeoanthropology, mathematics, computer science, etc. Many archaeological artefacts and sediments are porous and absorbent pottery, bones, textiles, soil , which represents an excellent environment for trapping these molecules and slowing down their degradation during the post-depositional period.
With the application of analytical chemistry, these can then be related back to previous vessel use, ancient diet, trade and economy. Although this interdisciplinary research began more than 25 years ago, the archaeological audience is slowly getting familiar with its scope and potential, despite the fact that, according to the recently published Analytical Chemistry in Archaeology Pollard et al.
Due to the nature of archaeological excavation, which is always a destructive process, the need for complementary research is therefore essential in order to extract the most information, which can in turn enhance archaeological interpretations. The basic analytical approach, adopted by the Organic Geochemistry Unit OGU , relies upon the identification of preserved molecules biomarkers ; matching their distribution to the compounds present in organisms that were most likely to have been exploited in the past.
Lipid residues of cooking and the processing of other organic commodities have been found to survive in archaeological pottery vessels as components of surface and absorbed residues for several thousand years. Characterisation of lipid extracts to commodity type is only possible through detailed knowledge of diagnostic compounds and their associated degradation products formed during vessel use or burial.
