LLNL Center for Microtechnology: Capabilities, Customers, Case Study-HANAA (Handheld Nucleic Acid Analyzer)
The polymerase chain reaction (PCR) is an enzyme-based chemical reaction that manufactures copies of one or more identifying regions of double-stranded DNA sequences (target sequences). These copies of target DNA are known as ''amplicons''. By creating millions of these copies of the identifying sequences (when they are present!), PCR allows researchers to detect by them, and hence the presence of the relevant organism, with techniques such as electrophoresis, flow cytometry, or spectrometry. Although there are numerous commercial PCR instruments that are designed for bench-top use in a laboratory, the challenges of building a battery-powered instrument that could perform such assays in the field.

Military Readiness: Civil Reserve Air Fleet Can Respond as Planned, but Incentives May Need Revamping
A letter report issued by the General Accounting Office with an abstract that begins "In the event of a national emergency, the Department of Defense (DOD) can use commercial aircraft drawn from the Civil Reserve Air Fleet to augment its own airlift capabilities. The Civil Reserve Air Fleet is a fleet of aircraft owned by U.S. commercial air carriers but committed voluntarily to DOD for use during emergencies. After the terrorist attacks of September 11, 2001, many air carriers experienced financial difficulties. This sparked concern about the fleet's ability to respond, if activated, and prompted the Subcommittee to ask GAO to determine whether the fleet could respond to an activation with the required number of aircraft and crews and in the required time frame. The Subcommittee also wanted to know whether the incentives used to attract and retain participants are effective."

On-Line Texture Diagnostics for Coated Conductor Manufacture. Final Report
This Phase I project was undertaken to assess the feasibility of implementing a particular diagnostic method for characterizing the crystallographic texture of high temperature superconductor (HTS) coated conductors on-line during their reel-to-reel continuous manufacture. Key factors in this technique were the use of an area detector to greatly reduce scan time, an x-ray mirror to enhance incident beam brightness, and an automation scheme for diffractometer control, tape motion control, and calculation and output of texture characterizations.

Optical Design Capabilities at Lawrence Livermore National Laboratory
Optical design capabilities continue to play the same strong role at Lawrence Livermore National Laboratory (LLNL) that they have played in the past. From defense applications to the solid-state laser programs to the Atomic Vapor Laser Isotope Separation (AVLIS), members of the optical design group played critical roles in producing effective system designs and are actively continuing this tradition. This talk will explain the role optical design plays at LLNL, outline current capabilities and summarize a few activities in which the optical design team has been recently participating.

Physics Survey Overview
An overview of a series of assignments of the branches of physics carried out by the Board on Physics and Astronomy of the National Research Council. It identifies further theories in physics and makes recommendations on preventive priorities. The Board on Physics and Astronomy (BPA) has conducted a new decadal survey of physics entitled ''Physics in a New Era''. The survey includes assessments of the main branches of physics as well as certain selected emerging areas. The various elements of the survey were prepared by separately-appointed National Research Council (NRC) committees. The BPA formed the Physics Survey Overview Committee (PSOVC) to complete the survey by preparing an overview of the field of physics to summarize and synthesize the results of the various assessments and to address cross-cutting issues that concern physics as a whole.

Power Systems Development Facility Gasification Test Run TC10
This report discusses Test Campaign TC10 of the Kellogg Brown & Root, Inc. (KBR) Transport Gasifier train with a Siemens Westinghouse Power Corporation (Siemens Westinghouse) particle filter system at the Power Systems Development Facility (PSDF) located in Wilsonville, Alabama. The Transport Gasifier is an advanced circulating fluidized-bed gasifier designed to operate as either a combustor or a gasifier in air- or oxygen-blown mode of operation using a particulate control device (PCD). The Transport Gasifier was operated as a pressurized gasifier during TC10 in air- (mainly for transitions and problematic operations) and oxygen-blown mode. Test Run TC10 was started on November 16, 2002, and completed on December 18, 2002. During oxygen-blown operations, gasifier temperatures varied between 1,675 and 1,825 F at pressures from 150 to 180 psig. After initial adjustments were made to reduce the feed rate, operations with the new fluidized coal feeder were stable with about half of the total coalfeed rate through the new feeder. However, the new fluidized-bed coal feeder proved to be difficult to control at low feed rates. Later the coal mills and original coal feeder experienced difficulties due to a high moisture content in the coal from heavy rains. Additional operational difficulties were experienced …

ULTRA LOW NOx INTEGRATED SYSTEM FOR NOx EMISSION CONTROL FROM COAL-FIRED BOILERS
ALSTOM Power Inc.'s Power Plant Laboratories, working in concert with ALSTOM Power's Performance Projects Group, has teamed with the U.S. Department of Energy's National Energy Technology Laboratory (DOE NETL) to conduct a comprehensive study to develop/evaluate low-cost, efficient NOx control technologies for retrofit to pulverized coal fired utility boilers. The objective of this project was to develop retrofit NOx control technology to achieve less than 0.15 lb/MMBtu NOx (for bituminous coals) and 0.10 lb/MMBtu NOx (for subbituminous coals) from existing pulverized coal fired utility boilers at a cost which is at least 25% less than SCR technology. Efficient control of NOx is seen as an important, enabling step in keeping coal as a viable part of the national energy mix in this century, and beyond. Presently 57% of U.S. electrical generation is coal based, and the Energy Information Agency projects that coal will maintain a lead in U.S. power generation over all other fuel sources for decades (EIA 1998 Energy Forecast). Yet, coal-based power is being strongly challenged by society's ever-increasing desire for an improved environment and the resultant improvement in health and safety. The needs of the electric-utility industry are to improve environmental performance, while simultaneously improving overall plant …

Isobutanol From Syngas in a Three Phase System
With growing interest in oxygenates as octane booster for automotive fuels, various synthesis routes for these chemicals are being investigated. Among others, alternative routes to isobutene, the C4-components in MTBE-synthesis are under investigation. A promising path to isobutene is the heterogeneously catalyzed CO-hydrogenation to isobutanol with following dehydration (Fig. 1). As shown by thermodynamical studies, the heterogeneously catalyzed CO-hydrogenation to isobutanol is not expected to experience any thermodynamic constraints. However, heterogeneous hydrogenation of CO is a very exothermic process, a problem which can only be partly solved when being conducted in a plug flow reactor. When carried out in reaction vessels with moving catalyst bed (e.g. three phase stirred tank), heat transfer problems can be resolved, along with additional benefits connected with this reactor type. Several heterogeneous catalytic systems have been under investigation for their capability of isobutanol synthesis from syngas. Most promising catalysts for an active and selective isobutanol synthesis from CO are modified high temperature methanol catalysts.
