A new, facile, general one-phase method of generating thiol-functionalized transition metal nanoparticles and surface modified by (co)polymers synthesized by the RAFT method is described. The method includes the steps of forming a (co)polymer in aqueous solution using the RAFT methodology, forming a collidal transition metal precursor solution from an appropriate transition metal; adding the metal precursor solution or surface to the (co)polymer solution, adding a reducing agent into the solution to reduce the metal colloid in situ to produce the stabilized nanoparticles or surface, and isolating the stabilized nanoparticles or surface in a manner such that aggregation is minimized. The functionalized surfaces generated using these methods can further undergo planar surface modifications, such as fuctionalization with a variety of different chemical groups, expanding their utility and application.

A service is provided to users of communication devices present in a geographic service area. Each device is associated with a specific user. The service comprises conditionally alerting a user, via his / her communication device, to a presence of another device of another user. The alerting occurs if the other user is registered as a buddy of the user and if a geographical distance between the user's device and the buddy's device is smaller than a pre-determined threshold. A succession of polling cycles is run. In each polling cycle, the mobile devices are sequentially polled based on location and according to a ranking determined in a preceding polling cycle that minimizes a value of a sum of terms. Each respective term indicates a respective difference between rankings of the mobile device of the respective user and of the mobile device of the buddy of the respective user.

An electroluminescent (EL) is provided comprising an anode, an organic electroluminescent element, and a cathode wherein the electroluminescent element contains, for example, a fluorescent 1,1′-binaphthyl derivative component of Formula (I) wherein R1, R2, R3 and R4 are individual substituents or a group of substituents, each of which may be selected from the group consisting of hydrogen, or alkyl of from 1 to about 25 carbon atoms; an alicyclic alkyl of from 3 to 15 carbon atoms; an aryl or substituted aryl with about 6 to about 30 carbon atoms; carbon atoms from 4 to 24 necessary to complete a fused aromatic ring of naphthalene, anthracene, perylene and the like; an alicyclic alkyl group with from about 3 to about 15 carbon atoms; a silicon atom which can be substituted with a trimethyl, diphenylmethyl, triphenyl group and the like; heteroaryl or substituted heteroaryl of from 5 to 24 carbon atoms, carbon atoms necessary to complete a fused heteroaromatic ring of furyl, thienyl, pyridyl, quinolinyl and other heterocyclic systems; an alkoxy, amino, alkyl amino or aryl amino of from 1 to about 25 carbon atoms; a halogen, a cyano group, and the like.
