Abstract: Provided are techniques that may include a disposable magnetic cell isolation holder having one or more passages that accommodate a magnetic retention material to facilitate magnetic cell isolation without adjustment of magnetic field parameters between isolation procedures using different magnetic particle sizes. When the magnetic cell isolation holder is coupled to a magnetic field generator, a first passage corresponding to a smaller particle size is positioned in a magnetic field where the magnetic field characteristics are different relative to a second passage, of a second holder or in the same holder, for use with another bead size.

Abstract: A bioreactor vessel includes a body having upper and lowerends and a hollow interior cavity formed in the body, the interior cavity located between the upper and lower ends, the interior cavity being configured to receive biomaterials for processing. The interior cavity includes a lower boundary that is angled toward the lower end of the body such that the vessel may be tilted to allow biomaterials within the interior cavity to be extracted and. concentrated and/or washed without the need for a separate bioprocessing device.

Abstract: Methods for treatment of sludge with microwave irradiation for improving its dewatering are provided. In one embodiment, the method includes exposing the sludge to microwave irradiation at a power density of between about 3 W/ml and about 17 W/ml. Turbidity, total solids content and overall dewaterability are improved when the microwave irradiation treatment is combined with another method for dewatering sludge, such as enzyme treatment, conditioning with a flocculating agent and mechanical dewatering.

Abstract: Photodetector arrangements, designs and fabrication techniques are described related to semiconductor nanostructures. Arrangements and techniques are described which utilize a nano-patterned template for growing semiconductor nanostructures and/or heterostructures. Resulting photodetectors are also described.

Abstract: The present invention is directed toward a method for fabricating low-defect nanostructures of wide bandgap materials and to optoelectronic devices, such as light emitting sources and lasers, based on them. The invention utilizes nanolithographically-defined templates to form nanostructures of wide bandgap materials that are energetically unfavorable for dislocation formation. In particular, this invention provides a method for the fabrication of phosphor-less monolithic white light emitting diodes and laser diodes that can be used for general illumination and other applications.
