Interface conditioning to improve efficiency and lifetime of organic electroluminescence devicesAn organic light emitting diode (“OLED”) display or device is typically comprised of: a transparent anode on a substrate; a hole injection/transporting layer; a light emitting layer (“emissive layer”); and a cathode, where one or more of these layers are organic in nature. When a forward bias is applied, holes are injected from the anode into the hole injection/transporting, and the electrons are injected from the cathode into the emissive layer. Both carriers are then transported towards the opposite electrode and allowed to recombine with each other. The location of this recombination is called the recombination zone and due to the recombination, the emissive layer produces visible light. There is some suggestion in a published patent application that incorporation of metal nano-particles within a polymer-based light emitting layer suppresses photo-oxidation and enhances luminous stability [Publication number US 2004/0217696 A1]. Yet another patent application suggests that acceleration of the radiative processes is achieved by incorporation of metal nano-particles within the hole transporting layer or within the light emitting layer of phosphorescence based OLEDs [Publication number US 2005/0035346]. The acceleration of the radiative processes is achieved by the interaction of the light emitting species with surface plasmon resonances in the vicinity of metal nano-particles. Non-radiative Förster-type processes are efficiently suppressed by encasing each nano-particle in organic capping molecules. In all of the above approaches, metal nano-particles were blended in one or more layers of the OLEDs. However direct incorporation of metal nano-particles into the active region or other layers within the OLED can cause additional negative effects. For example, it has been demonstrated that incorporation of a gold nano-particle even at low volume fraction of 3×10−5 within a light emitting polymer layer introduces strong hole blocking effects and a large increase in operating voltage [Publication number US 2004/0217696 A1 and Jong Hyeok Park et al., Chem. Mater. 2004, 16, 688]. Furthermore, incorporation of metal nano-particles in both fluorescence-based and phosphorescence-based OLEDs will likely quench emission and strongly deteriorate device performance. Encasing nano-particles in organic capping molecules is suggested to achieve an optimum balance between quenching and acceleration of the radiative processes of the triplets states [Publication number US 2005/0035346]. However achieving such a condition is not straightforward and capping of the metal nano-particles is not a well known procedure.
Method and system for detecting fake accounts in online social networksA system and method for detecting fake accounts in OSNs is proposed to aid the OSN provider 20 against fake users, wherein a social graph G of the OSN, with n nodes, a non-Sybil region GH and a Sybil region GS, is obtained and the following steps are performed: a trust value T(i)(v) is computed through i power iterations on each node v of the social graph G, i=0, 1, . . . O(log n) the power iterations distribute the trust value T(i)(v) from each node v to its neighbor nodes, after O(log n) power iterations, ranking nodes by a degree-normalized trust T ^ v = T ( w ) ⁡ ( v ) deg ⁡ ( v ) in order to obtain a ranked list of nodes, detecting fake accounts based on the obtained ranked list assigning intervals in the ranked list to a fake portion, determined by manual inspection means of the OSN provider, based on the degree-normalized trust of the nodes belonging to the intervals.
Method for producing amorphous based metalsAmorphous tungsten, cobalt, nickel, molybdenum, iron and alloys thereof can be formed by reducing metal-containing compositions to form the elemental metal wherein the particle size of the elemental metal is less than about 80 microns. This is oxidized in an oxygen-starved environment containing less than 3% oxygen and an inert gas to slowly oxidize the elemental metal. By oxidizing the metal under these conditions, the normal exotherm occurring during oxidation is avoided. The slow oxidation of the metal continues forming an amorphous metal oxide. The amorphous metal oxide can then be reacted in a reducing environment such as hydrogen to form the amorphous elemental metal. This amorphous elemental metal can then be reacted with a carburizing gas to form the carbide or ammonia gas to form the oitride or hexamethylsilane to form the silicide. This permits gas/solid reactions. The amorphous metal can also be used in a variety of different applications.
