Book Description
This book is an excellent compilation of cutting-edge research in heterogeneous catalysis and related disciplines – surface science, organometallic catalysis, and enzymatic catalysis. In 23 chapters by noted experts, the volume demonstrates varied approaches using model systems and their successes in understanding aspects of heterogeneous catalysis, both metal- and metal oxide-based catalysis in extended single crystal and nanostructured catalytic materials. To truly appreciate the astounding advances of modern heterogeneous catalysis, let us first consider the subject from a historical perspective. Heterogeneous catalysis had its beginnings in England and France with the work of scientists such as Humphrey Davy (1778–1829), Michael Faraday (1791–1867), and Paul Sabatier (1854–1941). Sabatier postulated that surface compounds, si- lar to those familiar in bulk to chemists, were the intermediate species leading to catalytic products. Sabatier proposed, for example, that NiH moieties on a Ni sur- 2 face were able to hydrogenate ethylene, whereas NiH was not. In the USA, Irving Langmuir concluded just the opposite, namely, that chemisorbed surface species are chemically bound to surfaces and are unlike known molecules. These chemisorbed species were the active participants in catalysis. The equilibrium between gas-phase molecules and adsorbed chemisorbed species (yielding an adsorption isotherm) produced a monolayer by simple site-filling kinetics.

Book Description
This book presents the evolution of the international monetary system from the gold standard to the monetary system in force today. It adopts a political economy approach, emphasizing the economic and political conditions under which an international monetary system can come into existence and be maintained over time. This approach highlights how the gradual transition in the international context from commodity money to fiat money has been led by the need for greater elasticity of money supply and smooth adjustments. This transition, however, raises the issue of how to guarantee, over time, the value of a money devoid of intrinsic value. By presenting a historical evolution, the book explains how the existence of an international monetary system based on money without intrinsic value can only occur when a particular balance of power exists at the international level that allows for the production of trust in a fiat money. The book is a must-read for scholars, researchers, and students in the fields of economic history and international monetary economics, interested in better understanding the evolution of the international monetary system.

Book Description
In the early 1870s, the global monetary system transitioned from bimetallism—a regime in which gold and silver currencies were tied at quasi-fixed exhange ratios—to the gold standard that was characterized by the use of (only) gold as the main currency metal by the largest and most advanced economies. The transition ocurred against the backdrop of both large supply shifts in global bullion markets in the 1850s and 60s and momentous political events, such as the Franco-Prussian war of 1870/71 and the subsequent foundation of the German empire. The causes for the transition have long been a matter of intense debate. This article discusses three separate but interrelated issues: (i) assessing the robustness of the pre-1870 bimetallic system to shocks—which includes a discussion of the appropriate use of Flandreau’s (1996) reference model; (ii) analyzing the transition from bimetallism to gold as a multi-stage currency game played by France and Germany; and (iii) evaluating the monetary debates at the German Handelstag conferences in the 1860s, to present a more complete narrative of the German discussion in the run-up to the transition.

Book Description
This book studies the so far unexplored operation of the international monetary system that prevailed before the emergence of the international gold standard in 1873. Conventional wisdom has it that the emergence of gold as a global anchor was both an inescapable and desirable evolution, given the exchange rate stability it provided and Britain's economic predominance. This study draws on a wealth of archival sources and abundant new statistical evidence (fully detailed in the appendix) to demonstrate that global exchange rate stability always prevailed before the making of the gold standard. This was despite the heterogeneity among national monetary regimes, based on gold, silver, or both. The reason for the stability before the establishment of the gold standard is France's bimetallic system. France, by being in a position to trade gold for silver, and vice versa, effectively pegged the exchange rate between gold and silver at its legal ratio of 15.5. Part I of the book studies exactly how this mechanism worked. Part II focuses on the respective behaviour of private concerns and arbitrageurs on the one hand, and authorities such as the Bank of France on the other hand, in order to underline the constraints and opportunities that were associated with bimetallism as an international regime. Finally, Part III provides a new view on the collapse of bimetallism and its replacement by a gold standard. It is argued that bimetallism might well have survived, and that the emergence of the gold standard was by no means inescapable. Rather, it resulted from a massive coordination failure at both national and international levels - a failure that was a preview of the interwar collapse of the gold standard.
