Abstract: An organic light emitting device is provided. The device has an anode, a cathode, and an emissive layer disposed between the anode and the cathode. The emissive layer further comprising an emissive material having the structure: M is a metal having an atomic weight greater than 40. R5 is an aromatic group. The emissive material itself is also provided. The emissive material provides an improved stability and efficiency.

Abstract: The invention provides xanthine phosphoribosyl transferase polypeptides and DNA (RNA) encoding xanthine phosphoribosyl transferase polypeptides and methods for producing such polypeptides by recombinant techniques. Also provided are methods for utilizing xanthine phosphoribosyl transferase polypeptides to screen for antibacterial compounds.

Abstract: A device is provided, having an anode, a cathode, and a first organic layer disposed between the anode and the cathode. The first organic layer produces phosphorescent emission when a voltage is applied between the anode and the cathode. An organic enhancement layer disposed between the first organic layer and the cathode is also provided. The organic enhancement layer is in direct contact with the first organic layer. The organic enhancement layer may comprise a material of structure (I): The material of structure I is thermally stable and is a high energy band gap material.

Abstract: A nickel base superalloy comprising 14.0 to 20.0 wt % cobalt, 13.5 to 17.0 wt % chromium, 2.5 to 4.0 wt % aluminium, 3.4 to 5.0 wt % titanium, 0 to 3.0 wt % tantalum, 3.8 to 5.5 wt % molybdenum, 0.035 to 0.07 wt % carbon, 0.01 to 0.04 wt % boron, 0.055 to 0.075 wt % zirconium, 0 to 0.4 wt % hafnium and the balance nickel plus incidental impurities. The nickel base superalloy is suitable for use as gas turbine engine high pressure compressor rotor discs or turbine discs. It is capable of operation at temperatures above 700° C. and has good fatigue crack propagation resistance, creep resistance and tensile strength.

Abstract: A Partner Relationship Management system (“PRMS”) accessible for sellers and buyers located remotely, whereby the buyers' access privileges are based on their relationship with the sellers. The PRMS comprising a server connected to the Internet and a pricing configurator which includes at least, a buyer profile module residing on the server and storing information on a plurality of buyers, logistics data and a price converter. The information on each buyer includes at least a delivery destination, and a pricing factor. The pricing factor is unique to each buyer. The pricing configurator converts an origin offer price, such as a free-on-board price, to a delivered price, such as a cost-insurance-freight price by considering the information of the buyer profiles and the logistics data.
