A novel method for separating an irradiated 60Cu or 61Cu or 64Cu respectively from a composition containing 60Ni or 61Ni or 64Ni respectively therein comprises dissolving the irradiated 60Cu or 61Cu or 64Cu in a solvent acid to form an acidic solubilized composition, feeding the acidic solubilized composition onto an ion exchange column and removing an eluent comprising 60Ni or 61Ni or 64Ni ions. In an aspect the eluent is further processed for 60Ni or 61Ni or 64Ni recovery and recycling to prepare future targets. In an aspect 60Cu or 61Cu or 64Cu respectively is temporarily trapped into the ion exchange column resin and held for subsequent recovery by addition of 0.5 N HCl to elute out the 60Cu or 61Cu or 64Cu for further use or labeling. An enhanced process for labeling compounds with highly purified 60Cu, 61Cu or 64Cu comprises loading 60Cu, 61Cu and 64Cu elute onto a concentrating cartridge, collecting the 0.5N HCl eluent and admixing therewith 10-μL of ligand and 3N HCl solution in a reaction line to form a 60 or 61 or 64Cu labeled product. In an aspect a further purification step comprises loading 10-mL sterile water into the reaction line and through the C18 Sep-Pak cartridge to further purify the labeled product which is adherent in the cartridge and recovering 60Cu, 61Cu and 64Cu each as a separate and independent purified product.
摘要:
A thin film and a method of making a thin film. The thin film comprises a patterned substrate, a smooth film of electric field tuned quantum dots solution positioned on the patterned substrate, and a thin layer of metal positioned on the thin film. The method begins by drop-casting a quantum dots solution onto a patterned substrate to create a thin film. While the quantum dots solution is drying, a linearly increasing electric filed is applied. The thin film is then placed in a deposition chamber and a thin layer of metal is deposited onto the thin film. Also included are a method of measuring the photoinduced charge transfer (PCT) rate in a quantum dot nanocomposite film and methods of forming a Shottky barrier on a transparent ITO electrode of a quantum dot film.

A method and portable electronic device provide pricing information to a customer and enable switching service from a current provider to a desired provider in response to a selection by the customer on the portable electronic device. In the method, pricing information associated with the current provider and with competitor providers is gathered. Then, the portable electronic device displays the respective pricing information and each associated provider for selection by the customer. In response to the selection of the desired provider by the customer, the portable electronic device automatically deactivates service from the current provider and activates service from the desired provider.

A control system comprising a control input device having a movable magnet, a pole-piece frame arrangement positioned about the magnet and positioned therein at least two magnetic flux sensors for sensing movement of the magnet in a given direction. The control system further comprises a monitoring arrangement for monitoring the output signal of each of the sensors and permits the input device to control the system only when the output of the sensors are within a predefined range. This multiple sensing provides a fail-safe in the event that one of the sensors generates an erroneous signal.

A method of fabricating organic solar panels with transparent contacts. The method uses a layer-by-layer spray technique to create the anode layer. The method includes placing the substrate on a flat magnet, aligning a magnetic shadow mask over the substrate, applying photoresist to the substrate using spray photolithography, etching the substrate, cleaning the substrate, spin coating a tuning layer on substrate, spin coating an active layer of P3HT/PCBM on the substrate, spray coating the substrate with a modified PEDOT solution, and annealing the substrate.

There is provided a system and method for rule-based dynamic server-side streaming manifest files. There is provided a method comprising receiving a request to provide a first video content for playback, evaluating a plurality of rules for the first video content, generating a dynamic manifest file referencing the first video content, and providing the dynamic manifest file in response to the request, thereby enabling an application to playback the first video content for output on a display by interpreting the dynamic manifest file. The rules may implement various features such as dynamic advertisement insertion, load balancing, client customization, user and device targeting, enhanced security mechanisms, global announcements, and others. As streaming protocols are widely supported by default on many client platforms, the dynamic manifest files can be utilized in a user friendly and transparent manner compared to client-side solutions requiring cumbersome client software installations.

There is described a method for determining a value of a zero point offset of a yaw rate sensor. The method comprises measuring over time the output of the yaw rate sensor, determining whether the measured output has remained within a set of limits for a pre-determined period and if it is determined that the measured output has remained within the limits for the pre-determined period, using at least one measured value of the output to determine the value of the zero point offset.

The fabrication and characterization of large scale inverted organic solar array fabricated using all-spray process is disclosed. Solar illumination has been demonstrated to improve transparent solar photovoltaic devices. The technology using SAM has potential to revolute current silicon-based photovoltaic technology by providing a complete solution processable manufacturing process. The semi-transparent property of the solar module allows for applications on windows and windshields. The inventive arrays are more efficient than silicon solar cells in artificial light environments, permitting use of the arrays in powering microelectromechanical systems and in integration with microelectromechanical systems.
