Full bibliographies are in could be the basic descriptive part of a university course on the subject. many cases unnecessary because of the monumental work of Ridge (Ridge, Many teachers of economic and mining geology prefer to lecture on the 1972 and 1976). formative geological processes and origin of mineral deposits, and most of The Scope, Purpose and Layout of the Book Terminology. This is a persistent problem in geology. What I have tried to the existing textbooks do likewise. The Atlas is intended to be a compen Air, sea, surface water and soil support life, from which comes our food; the dium of descriptive material on which a more analytical series of lectures, or do is use a consistent, and internationally acceptable set of terms, making as much use as possible of the recent attempts by international organizations to fossil remains of life, that is: coal, oil and gas, together with solar and course of reading, could be based.
During the century after 1750, Great Britain absorbed much of the world's supply of gold into its pockets, cupboards, and coffers when it became the only major country to adopt the gold standard as the sole basis of its currency. Over the same period, the nation's emergence was marked by a powerful combination of Protestantism, commerce, and military might, alongside preservation of its older social hierarchy. In this rich and broad-ranging work, Timothy Alborn argues for a close connection between gold and Britain's national identity. Beginning with Adam Smith's Wealth of Nations, which validated Britain's position as an economic powerhouse, and running through the mid-nineteenth century gold rushes in California and Australia, Alborn draws on contemporary descriptions of gold's value to highlight its role in financial, political, and cultural realms. He begins by narrating British interests in gold mining globally to enable the smooth operation of the gold standard. In addition to explaining the metal's function in finance, he explores its uses in war expenditure, foreign trade, religious observance, and ornamentation at home and abroad. Britons criticized foreign cultures for their wasteful and inappropriate uses of gold, even as it became a prominent symbol of status in more traditional features of British society, including its royal family, aristocracy, and military. Although Britain had been ambivalent in its embrace of gold, ultimately it enabled the nation to become the world's most modern economy and to extend its imperial reach around the globe. All That Glittered tells the story of gold as both a marker of value and a valuable commodity, while providing a new window onto Britain's ascendance after the 1750s.

Novel Non-Precious Metal Electrocatalysts for Oxygen Electrode Reactions by Hui Yang,Yongjun Feng, Nicolas Alonso-Vante Pdf
Research on alternative energy harvesting technologies, conversion and storage systems with high efficiency, cost-effective and environmentally friendly systems, such as fuel cells, rechargeable metal-air batteries, unitized regenerative cells, and water electrolyzers has been stimulated by the global demand on energy. The conversion between oxygen and water plays a key step in the development of oxygen electrodes: oxygen reduction reaction (ORR) and oxygen evolution reaction (OER), processes activated mostly by precious metals, like platinum. Their scarcity, their prohibitive cost, and declining activity greatly hamper large-scale applications. This issue reports on novel non-precious metal electrocatalysts based on the innovative design in chemical compositions, structure, and morphology, and supports for the oxygen reaction.

"This is the story of silver's transformation from soft money during the nineteenth century to hard asset today, and how manipulations of the white metal by American president Franklin D. Roosevelt during the 1930s and by the richest man in the world, Texas oil baron Nelson Bunker Hunt, during the 1970s altered the course of American and world history. FDR pumped up the price of silver to help jump start the U.S. economy during the Great Depression, but this move weakened China, which was then on the silver standard, and facilitated Japan's rise to power before World War II. Bunker Hunt went on a silver-buying spree during the 1970s to protect himself against inflation and triggered a financial crisis that left him bankrupt. Silver has been the preferred shelter against government defaults, political instability, and inflation for most people in the world because it is cheaper than gold. The white metal has been the place to hide when conventional investments sour, but it has also seduced sophisticated investors throughout the ages like a siren. This book explains how powerful figures, up to and including Warren Buffett, have come under silver's thrall, and how its history guides economic and political decisions in the twenty-first century"--Publisher's description
