Molecular biological enhancement of coal biodesulfurization. [Rhodococcus, thiobacillus] (open access)

Molecular biological enhancement of coal biodesulfurization. [Rhodococcus, thiobacillus]

The objective of this project is to produce one or more microorganisms capable of removing the organic and inorganic sulfur in coal. The original specific technical objectives of the project were to: clone and characterize the genes encoding the enzymes of the 4S'' pathway (sulfoxide/sulfone/sulfonate/sulfate) for release of organic sulfur from coal; return multiple copies of genes to the original host to enhance the biodesulfurization activity of that organism; transfer this pathway into a fast-growing chemolithotropic bacterium; conduct a batch-mode optimization/analysis of scale-up variables.

NQR-NMR studies of higher alcohol synthesis Cu-Co catalysts (open access)

NQR-NMR studies of higher alcohol synthesis Cu-Co catalysts

The primary objective of the project is to investigate the magnetic nature of the higher alcohol synthesis catalyst-Cu/Co supported on specific supports: chromia and titania with and without an alkali metal promoter, and examine the relations between catalytic and magnetic properties.

Modeling of water spraying of field releases of hydrogen fluoride (open access)

Modeling of water spraying of field releases of hydrogen fluoride

The effectiveness of water sprays to absorb HF releases has been recently demonstrated by extended laboratory and field tests. In this paper computer simulations are presented of the Hawk, Nevada Test Site, series of field tests, along with parametric studies of several cases which have not been studied in the field. The model used in these simulations, HFSPRAY, treats the gas-phase as an Eulerean fluid whereas the spray is described according to the Lagrangian approach by a finite number of drops of varying size and trajectory. HFSPRAY simulates the momentum, mass and energy interactions between a water spray and a turbulent plume of HF in air; it is capable of predicting the flow velocities, temperature, water vapor and HF concentration fields in two-dimensional large-geometries, for spraying in any direction, (i.e., down-flow, inclined-down-flow, up-flow, and co-current horizontal flow). 15 refs., 21 figs.

Photoinitiated electron transfer in multi-chromophoric species: Synthetic tetrads and pentads (open access)

Photoinitiated electron transfer in multi-chromophoric species: Synthetic tetrads and pentads

This research project involves the design, synthesis and study of the molecules which mimic many of the important aspects of photosynthetic electron and energy transfer. Specifically, the molecules are designed to mimic the following aspects of natural photosynthetic multistep electron transfer: electron donation from a tetrapyrrole excited singlet state, electron transfer between tetrapyrroles, electron transfer from tetrapyrroles to quinones, and electron transfer between quinones with different redox properties. In addition, they model carotenoid antenna function in photosynthesis (singlet-singlet energy transfer from carotenoid polyenes to chlorophyll) and carotenoid photoprotection from singlet oxygen damage (triplet-triplet energy transfer from chlorophyll to carotenoids).
