Abstract: Provided are catalytic assemblies which include a hollow fiber membrane permeable to a gas; a reactive coating permeable to the gas and a contaminant; and a plurality of catalytic nanoparticles embedded in the reactive coating adapted to catalyze a reaction between the gas and the contaminant. Also provided are preparation methods for the catalytic assemblies, and use thereof for treating contaminated water.

Abstract: A process for the production of extra fine spherical metal powders by chemical vapor deposition and dissolution techniques, including metal carbonyls, wherein the metal containing process gas is propelled upwardly through a heated reactor.

Abstract: A very large virtual volume (e.g., in excess of 500 GB) is formed by distributing the disks in eleven, six-disk RAID-5 sets across the six busses of a primary local back-end controller. A spare disk is provided on each of the six busses. Each RAID-5 set is protected from the failure of a single disk by the spare disks on the busses, which can use the parity data stored in a RAID-5 set to rebuild the data stored on a failing disk and thereby restore redundancy to the RAID-5 set. Each RAID-5 set is also protected from the failure of a bus by the parity inherent in RAID-5. The RAID-5 sets are striped by a front-end controller connected to the primary local back-end controller, and the striped RAID-5 sets are presented to a host computer as a very large virtual volume. If the individual disks are 9.1 GB in size, the size of the very large virtual volume can reach 500.5 GB.

Abstract: A device for characterizing a cell or particle includes a channel having an inlet and an outlet, the channel containing a moving fluid therein for carrying the cell or particle from the inlet to the outlet. The device includes a detector for detecting the presence of a cell or particle along portion of the channel, the detector including a first detecting position, a second detecting position, and a third detecting position. The device further includes a light source providing an optical gradient disposed within the channel and between the second and third detecting positions. A control system is coupled to the detector to receive and process detected signals from the detector. During operation, the amount of time that a cell or particle takes to flow through a first distance (i.e., its time-off-flight) is measured. The cell or particle is then flowed past a second, downstream distance in the presence of an optical gradient and its time-of-flight is measured.

Abstract: A continuous method for generating substantially submicron sized metal particles in a liquid dispersion of known viscosity. Metal carbonyl gas and an inert carrier gas, with an optional dilutant gas, are introduced into a heated liquid bath wherein the metal carbonyl decomposes into submicron sized pure metal particles. The particles are suspended in the liquid. The liquid is processed to form slurries and pastes.
