摘要:
A photosensitive cell includes an anode and a cathode; a donor-type organic material and an acceptor-type organic material forming a donor-acceptor junction connected between the anode and the cathode; and an exciton blocking layer connected between the acceptor-type organic material of the donor-acceptor junction and the cathode, the blocking layer consisting essentially of a material that has a hole mobility of at least 10−7 cm2/V-sec or higher, where a HOMO of the blocking layer is higher than or equal to a HOMO of the acceptor-type material.
摘要:
Organic light emitting devices are described wherein the emissive layer comprises a host material containing an emissive molecule, which molecule is adapted to luminesce when a voltage is applied across the heterostructure, and the emissive molecule is selected from the group of phosphorescent organometallic complexes, including cyclometallated platinum, iridium and osmium complexes. The organic light emitting devices optionally contain an exciton blocking layer. Furthermore, improved electroluminescent efficiency in organic light emitting devices is obtained with an emitter layer comprising organometallic complexes of transition metals of formula L2MX, wherein L and X are distinct bidentate ligands. Compounds of this formula can be synthesized more facilely than in previous approaches and synthetic options allow insertion of fluorescent molecules into a phosphorescent complex, ligands to fine tune the color of emission, and ligands to trap carriers.

A method of surgical dissection of tissue with a dissector comprising: an elongate shaft comprising a proximal portion and a distal portion, wherein the distal portion comprises a plurality of segments that articulate with respect to one another and the plurality of segments includes a distal segment having a distal end; and a handle attached to the proximal portion of the shaft, wherein the handle comprises controls for articulating the plurality of segments of the distal portion of the shaft with respect to one another, comprising the steps of: positioning the distal end of the dissector in a body; advancing the distal end through the body to dissect tissue; and simultaneously articulating the plurality of segments with respect to one another. A method of surgical dissection of tissue and guiding a second device to a desired physiological location with a first device.

A system and method for consistently, reliably and equitably discounting medical bills of self-pay patients includes a networked discounting engine operably coupled to a plurality of databases. The discounting engine is adapted to receive patient account data from one or more patient registration systems. Based upon the patient account data received, the discounting engine accesses the plurality of databases to determine financial, asset and demographic attributes for a patient or responsible party. Based upon the patient account data received, and the determined financial, asset and demographic variable values, the discounting engine determines weights and points. Weights and points are then combined by the discounting engine to determine a weighted discount percentage to be applied against the patient's outstanding account balance. The discounting engine then generates and sends to the patient registration system an output file containing the discount percentage and other patient information. This information along with other billing information is communicated to a patient accounting system for preparing a discounted bill.
摘要:
A method for observing voltage contrast from buried structures in SOI. The method includes depositing a thin transparent metal layer over the BOx to dissipate charging of the oxide, and using a low FIB beam current to avoid damage due to ion implantation and direct ion beam damage.
