Abstract: Variable flow rate fuel ejectors, and methods of use therefore, are disclosed. One variable flow rate ejector includes a primary nozzle, a needle, a motor, a first stop portion, and a first impact-absorbing portion. The primary nozzle is connected to a first inlet chamber to receive a first fluid and transmit a flow of the first fluid through the primary nozzle opening. The needle is disposed to create a gap between the tapered portion of the needle and the primary nozzle opening. The motor is coupled to axially move the needle to vary a size of the gap. The first stop portion delimits the axial movement of the needle in a direction of retraction of the needle from the primary nozzle opening. The first impact-absorbing element is positioned to contact the first stop portion or the needle, respectively, when the needle is fully retracted from the primary nozzle opening.

Abstract: The present invention provides a method for controlling colocalization of two or more proteins in a cell. The method comprises expressing the proteins, scaffold RNA molecules having binding motifs for the proteins, and a trigger RNA molecule in the cell. In the presence of the trigger RNA molecule, a scaffold may be assembled (ON) by the scaffold RNA molecules via hybridization such that the proteins may be colocalized; or disassembled (OFF) such that the proteins may be separated and not colocalized. The proteins may provide a biological activity when colocalized or not colocalized.
Abstract: A process for aligning discontinuous fibers, and composite products and mats comprised of highly aligned discontinuous fibers, including products of the process. Aligned discontinuous fiber composite products include a matrix of fibers, each fiber having a longitudinal fiber axis, the composite comprising a free, uncut edge extending along an edge axis. The longitudinal fiber axis of a majority of the fibers in the composite product are aligned within a predetermined alignment tolerance of an alignment axis non-parallel to the edge axis. Aligned discontinuous fiber mats may have a first areal density of fibers in a first region of the composite located inward relative to the free, uncut edge, and a second area density at or adjacent to the free, uncut edge.

Abstract: A carbon nanotube-based sensor comprises a fabric, and a plurality of carbon nanotubes coated on the fabric. The plurality of carbon nanotubes form a network in a plane of the fabric. At least two tap points are coupled to the plurality of carbon nanotubes coated on the fabric. A first of the plurality of tap points is separated from a second of the plurality of tap points, where the first and second tap points have a resistance there between. Application of a force on the fabric, from outside the plane of the fabric, causes a change in the resistance between the first and second tap points.
