Manipulation of Groundwater Colloids for Environmental Restoration
This valuable resource discusses several strategies of manipulating colloids for environmental restoration, identifies advantages and disadvantages of each strategy, and considers obstacles limiting the application of each strategy. Approaches evaluated include the following: Chemical modification of subsurface systems to mobilize or deposit colloids in situ Altering the mobility of microorganisms to improve delivery of microbes for bioremediation Manipulating colloids or biocolloids (bacteria) to change aquifer permeability to either enhance bioremediation or create in situ barriers Introducing modified colloids, surfactants, and emulsions to control colloid mobility or to increase recovery...
Improving the Scientific Basis for Managing DOE's Excess Nuclear Materials and Spent Nuclear Fuel
The production of nuclear materials for the national defense was an intense, nationwide effort that began with the Manhattan Project and continued throughout the Cold War. Now many of these product materials, by-products, and precursors, such as irradiated nuclear fuels and targets, have been declared as excess by the Department of Energy (DOE). Most of this excess inventory has been, or will be, turned over to DOE's Office of Environmental Management (EM), which is responsible for cleaning up the former production sites. Recognizing the scientific and technical challenges facing EM, Congress in 1995 established the EM Science Program (EMSP) to develop and fund directed, long-term research t...
Transparent Electronics
The challenge for producing “invisible” electronic circuitry and opto-electronic devices is that the transistor materials must be transparent to visible light yet have good carrier mobilities. This requires a special class of materials having “contra-indicated properties” because from the band structure point of view, the combination of transparency and conductivity is contradictory. Structured to strike a balance between introductory and advanced topics, this monograph juxtaposes fundamental science and technology / application issues, and essential materials characteristics versus device architecture and practical applications. The first section is devoted to fundamental materials ...
Handbook of Inorganic Compounds
For anyone that needs property data for compounds, CASRN numbers for computer or other searches, a consistent tabulation of molecular weights to synthesize inorganic materials on a laboratory scale, or information on commercial and other uses for various compounds, this volume is the perfect reference. This second edition is fully revised and updated. New data include optical inorganics, radiation detection inorganics, thermochromic compounds, piezochromic compounds, metal ion coordination complexes, expanded crystallographic and structural data for inorganics, catalysts, superconductors, and luminescent (fluorescent and phosphorescent) inorganics.
Understanding Stone Tools and Archaeological Sites
Understanding Stone Tools and Archaeological Sites is a valuable volume of investigative archaeology focuses on stone tools, the artifacts produced by these tools, and the revealing debris left behind at sites where they were produced. The majority of study sites discussed are in western North America, including Alberta's own Head-Smashed-In Buffalo Jump, a World Heritage Site. Suitable for both the scholar and the interested layperson, provides a comprehensive study in archaeological lithic analysis. This concise, "hands-on" guide to practical exploration at stone tool sites will become required reading for those pursuing studies of any sort in prehistoric lithic artifacts. The inclusion of maps, illustrations, and photographs broadens the reader's understanding of deriving meaning and relevance in the study of stone tool technology.
Prisoners, Lovers, & Spies
This “engrossing study” of invisible ink reveals 2,000 years of scoundrels, heroes and their ingenious methods for concealing messages (Kirkus). In Prisoners, Lovers, and Spies, Kristie Macrakis uncovers the secret history of invisible ink and the ingenious way everything from lemon juice to Gall-nut extract and even certain bodily fluids have been used to conceal and reveal covert communications. From Ancient Rome to the Cold War, spies have been imprisoned or murdered, adultery unmasked, and battles lost because of faulty or intercepted secret messages. Yet, successfully hidden writing has helped save lives, win battles, and ensure privacy—at times changing the course of history. Mac...
