This report covers the research on inorganic liquid lasers. The objectives of the project were to evaluate inorganic liquid laser materials in high average power and high brightness applications. The first part of this was achieved by the construction of a repetitively pulsed system and operating it at average power levels in excess of 400 watts, with an overall efficiency of more than 2%. It is estimated that, with relatively straightforward modification, average power levels of 1 kW could be...

LONG-TERM GOALS. A major oceanographic problem is to understand the biogeochemical dynamics of the upper kilometer of the water column. Such an understanding is fundamental to the predictability of the processes partitioning carbon between atmosphere and ocean and of those redistributing carbon and associated elements within the water column. Key to predictability is understanding day-to-day variability of processes governing abundances of carbon species (dissolved and particulate, inorganic...

The contamination of groundwater in the United States is a challenging problem. It has been estimated that 300,000-400,000 contaminated waste sites may account for 750 billion dollars of remediation over the next three decades (National Academy of Sciences, 1994). The successful treatment of contaminated groundwater is a further challenge. Conventional treatment methods, such as pump and treat systems, have been shown to be somewhat ineffective. Selection of a groundwater treatment technology...

Our long-term goal is to understand the biogeochemical dynamics of the upper kilometers of the water column. Such an understanding is fundamental to the prediction of the processes partitioning carbon between atmosphere and ocean and to the redistribution of carbon and associated elements within the water column. Key to predictability is understanding day-to-day to seasonal variability of processes governing carbon species (dissolved and particulate, inorganic and organic) in the water column.

LONG TERM GOAL. Our long-term goal is to understand the action of dissolved enzymes in organic material (OM) degradation and microbial growth. Microorganisms and their enzymes are essential for decomposition of much natural and pollutant OM. In marine environments, much of this material is unavailable for direct incorporation or degradation by microorganisms, either because it is itself too large to be ingested by the cell, or because it is sorbed to some large organic or inorganic substratum....

Nickel and nickel-base alloys can be successfully adhesive bonded using presently available techniques and adhesives. Relatively little work has been done on adhesive bonding of nickel-base alloys, however, because most nickel-base alloys are used at temperatures above the present maximum service temperatures of organic adhesives or under corrosive conditions. Inorganic adhesives off sufficient and low enough maturing temperature have not been developed to compete effectively with brazing and...

This protocol outlines how to prepare nano-sized materials for examination using electron microcopy and in particular as an aid for particle size analysis. The type of sample preparation is dependent on the type of material. The protocol subdivides techniques for preparation of wet and dry samples, as well as conductive vs. non-conductive samples. Nanomaterial samples pose challenges when preparing samples for imaging. One challenge is that these materials tend to agglomerate or aggregate and...

Metal-organic frameworks (MOFs) are a relatively new class of porous materials, assembled from inorganic metal nodes and organic ligands. MOFs have garnered significant attention in the porous materials and adsorption field in recent years due to their various attractive features such as high surface areas and pore volumes, uniform pore sizes which are easily tunable, chemically functionalized adsorption sites, and potential for post-synthetic modification (PSM). These features give MOFs...
