Geological specimens are often complex materials that require different analytical methods for their characterization. The parameters of interest may include the chemical composition of major, minor and trace elements. The chemical compounds incorporated in the minerals, the crystal structure and isotopic composition need to be considered. Specimens may be highly heterogeneous thus necessitating analytical methods capable of measurements on small sample volumes with high spatial resolution and sensitivity. Much essential information on geological materials can be obtained by using ion or photon beams. In this chapter the authors describe the principal analytical techniques based on particle accelerators, showing some applications that are hardly possible with conventional methods. In particular, the following techniques will be discussed: (1) Synchrotron radiation (SR) induced X-ray emission (SRIXE) and particle-induced X-ray emission (PEE) and other ion beam techniques for trace element analysis; and (2) Accelerator mass spectrometry (AMS) for ultra sensitive analysis of stable nuclides and long-lived radionuclides. In most of the cases also the possibilities of elemental and isotopic analysis with high resolution will be discussed.

The goal of this article is to illustrate the use of synchrotron radiation for investigating surface chemical reactions by photoelectron spectroscopy. A brief introduction and background information is followed by examples of layer resolved spectroscopy, oxidation and sulfidation of metallic, semiconducting and oxide surfaces.

This issue of Alternative Fuel News highlights the accomplishments of the Clean Cities coalitions during the past 5 years. Now Clean Cities advocates in city after city across the US are building stations and driving alternative fuel vehicles, in addition to enhancing public awareness.

SolMaT works with manufacturers to lower the cost of manufacturing components for concentrating solar power systems.

Transpired air collectors preheat building ventilation air by using the building's ventilation fan to draw fresh air through the system. The intake air is heated as it passes through the perforated absorber plate and up the plenum between the absorber and the south wall of the building. Reduced heating costs will pay for the systems in 3--12 years.

The November 1998 of Turning Point highlights the US Industrial Electric Motor Systems Market Opportunities Assessment Report--the first of its kind in 20 years. Sponsored by DOE's Motor Challenge Program, the comprehensive assessment describes motor-system use in the industrial sector. This issue also introduces the latest version of MotorMaster+ motor management software-- MotorMaster+ 3.0, and includes a case study on a fan system optimization project that yielded significant energy and cost savings for a Louisiana-Pacific plant.

Concentrating solar power (CSP) technologies, including parabolic troughs, power towers, and dish/engines, have the potential to provide the world with tens of thousands of megawatts of clean, renewable, cost-competitive power.

DOE's Concentrating Solar Power (CSP) program is collaborating with its partners in the private sector to develop two new solar technologies -- power towers and dish/engines -- to meet the huge commercial potential for solar power. Concentrating solar power plants produce electric power by first converting the sun's energy into heat, and then to electricity in a conventional generator.

This document provide compiled list of U.S. Congressional Serial Set that were assigned serial numbers but not used. The list compiled to account for missing numbers from the U.S. Congressional Serial Set. Much of the information was extracted from old hand-written records and notations in copies of the Indexes to Reports and Documents and the Numerical Lists and Schedules of Volumes of the various Congresses maintained by the U.S. Government Printing office.
