Another even more significant use of methyl alcohol can be as a fuel in its own right in fuel cells. In recent years, in cooperation with Caltech s Jet Propulsion Laboratory (JPL), we have developed an efficient new type of fuel cell that uses methyl alcohol directly to produce electricity without the need to first catalytically convert it to produce hydrogen.

The Jet Propulsion Laboratory and Giner Inc. have an on-going collaboration to develop electrochemical DMFC stacks. A 5-cell stack (with an active area of the electrode of 25 cm ) was designed and constructed for operation with unpressurized air. " The performance characteristics of the stack at two operating temperatures (60 and 90 °C) and two 1 M methanol flow rates (5 and 2 liter/min), are rather good 2 V at 250 mA/cm at 90 C. The variation in cell-to-cell performance was very small. Efforts are being made at several other laboratories (e.g., LANL, H-Power) to design, construct, and test DMFC stacks.

Improvements in solid polymer electrolyte materials have extended the operating temperatures of direct methanol PEFCs from 60 C to almost 100 C. Electrocatalyst developments have focused on materials that have higher intrinsic activity. Researchers at the University of Newcastle upon Tyne have reported over 200 mA/cm at 0.3 V at 80 C with platinum/ruthenium electrodes having platinum loading of 3.0 mg/cm. The Jet Propulsion Laboratory in the U.S. has reported over 100 mA/cm at 0.4 V at 60 C with platinum loading of 0.5 mg/cm. Recent work at Johnson Matthey has clearly shown that platinum/ruthenium materials possess substantially higher intrinsic activity than platinum alone (45). 

With the exception of calibration, the measurement problems that were apparent in 1970, at the time of publication of the fost air quality criteria document on photochemical oxidants, have essentially been solved for ozone. This remarkable achievement is the result of unstinting efforts by people working at epa s National Environmental Research Center, North Carolina the National Bureau of Standards private research contractors sponsored primarily by epa private instrument manufacturers the Jet Propulsion Laboratory of the California Institute of Technology the Air and Industrial Hygiene Laboratory, California Department of Health the Air Pollution Research Center of the University of California at Riverside and the California Air Resources Board (carb). 

There are two basic ways to look for explosive material. They differ in their point of focus. Some sensors seek the mass of explosive material within a device. These are particularly useful when the device is well sealed and its surface is well cleaned of stray explosive molecules, or when the explosive being used is nonaromatic, that is, it does not readily release molecules from its bulk. We will refer to these as bulk sensors. They include X-ray techniques, both transmission and backscatter neutron activation in several techniques y -ray excitation, in either transmission or backscatter modes and nuclear resonance techniques, either nuclear magnetic resonance (NMR) or nuclear quadrupole resonance (NQR). Bruschini [1] has described these thoroughly. They are also described by the staff of the Jet Propulsion Laboratory [2], The following forms a very brief synopsis.

The chemistry of the troposphere (the layer of the atmosphere closest to earth s surface) overlaps with low-temperature combustion, as one would expect for an oxidative environment. Consequently, the concerns of atmospheric chemistry overlap with those of combustion chemistry. Monks recently published a tutorial review of radical chemistry in the troposphere. Atkinson and Arey have compiled a thorough database of atmospheric degradation reactions of volatile organic compounds (VOCs), while Atkinson et al. have generated a database of reactions for several reactive species with atmospheric implications. Also, Sandler et al. have contributed to the Jet Propulsion Laboratory s extensive database of chemical kinetic and photochemical data. These reviews address reactions with atmospheric implications in far greater detail than is possible for the scope of this review. For our purposes, we can extend the low-temperature combustion reactions [Equations (4) and (5)], whereby peroxy radicals would have the capacity to react with prevalent atmospheric radicals, such as HO2, NO, NO2, and NO3 (the latter three of which are collectively known as NOy) ...
