摘要:
Systems & methods for sorting single-walled carbon nanotubes (SWNTs) using an iDEP-based sorting device. The device includes an inlet channel with a constriction and the inlet channel splits into multiple different channels after the constriction—the multiple channels includes a center channel and at least one side channel. A sample is introduced into the iDEP sorting device containing a plurality of SWNTs of different lengths suspended in a fluid. An electrical field is applied to the sample between a first electrode in the center channel and a second electrodes at a proximal end of the inlet channel. The applied electrical field causes longer SWNTs to move towards the side channels while the shorter SWNTs move towards the center channel. Accordingly, a first plurality of shorter SWNTs is then collected from the center channel and a second plurality of longer SWNTs is collected from the at least one side channel.
摘要:
The invention relates to a photovoltaic concentrator module with multifunction frame and also to a method for production thereof. The concentrator module has a lens- and a base plate, between which a frame extends. Between the lens plate and the frame and/or the base plate and the frame, two sealing compounds and/or adhesive compounds extend, which compounds differ with respect to their hardening time and/or gas permeability.

In some aspects of the disclosure, a workpiece retention device for securing plate-like workpieces to a workpiece movement unit of a machine tool includes first and second workpiece clamping elements and a clamping drive by which the workpiece clamping elements can be moved towards one another starting from an initial relative position in order to clamp a workpiece that is arranged between the workpiece clamping elements. The workpiece retention device also includes an adjustment device that can adjust the initial relative position of the workpiece clamping elements.

The present invention relates to a method for operating a predictive adaptive front lighting for a vehicle with headlamps and a controller. The method includes the steps of receiving a vehicle position; identifying a map location of the vehicle; determining a most likely path of the vehicle based on the map location; locating a target point on the most likely path of the vehicle; adaptively changing a distance between the vehicle and the target point; calculating a desired swivel angle for the vehicle headlamps based on the most likely path of the vehicle; and swiveling the headlamps according to the desired swivel angle.

Multilayer interference pigment consisting of a transparent carrier material coated with alternating layers of metal oxides of low and high refractive index, the difference in the refractive indices being at least 0.1, which is obtainable by alternate coating of the transparent carrier material with a metal oxide of high refractive index and with a metal oxide of low refractive index in a wet process by hydrolysis of the corresponding water-soluble metal compounds, separation, drying and, if desired, calcination of the resulting pigment.
摘要:
In a fuel delivery unit for a motor vehicle, having a delivery pump which has a preliminary stage and a main stage, an outlet channel of the preliminary stage is guided radially outward and configured such that it rises upward. An inlet channel of the main stage is guided laterally past the preliminary stage. In accordance with this design, impellers of the delivery pump can be arranged particularly low down and gas bubbles are guided away out of the preliminary stage in a very simple manner.

A feed unit, in particular for the feed of fuel, has an electric drive motor with a pump unit coupled with it, the pump unit being built of two housing parts and a pump wheel arranged between them. The two housing parts and the pump wheel are each developed as a casting or compression molding from a mixture of graphite and plastic. The end surfaces of the pump wheel and of the two housing parts which contact each other are roughened.

A tubular flexible probe for introduction into the trachea and, respectively, into the bronchial system, has a continuous first lumen with a connecting piece provided at the proximal inlet end for connection to a suction device and, extending therebeside, a further small lumen having a smaller diameter than the first lumen. A wall of the smaller lumen has a recess in the zone of the proximal inlet end of the probe with an elastic connecting hose being inserted with one end in the smaller lumen in the recess. For the alternating introduction of medicaments and, respectively, irrigation solution at a high exit velocity at the distal probe end through the smaller lumen and for removing secretions or the like by suction, the probe has a lenght of about 30-55 cm and an outer diameter of about 5-8 mm. The large first lumen has a diameter of about 3-4.5 mm, the small lumen has a diameter of about 1 to maxially 2 mm, and the two lumens extend from the proximal end up to the distal, rounded end of the probe in side-by-side relationship and in parallel to the probe axis. An attachment for a syringe is formed at the inlet end of the connecting hose.
