Metal films are deposited with uniform thickness and excellent step coverage. Copper metal films were deposited on heated substrates by the reaction of alternating doses of copper(I) NN′-diisopropylacetamidinate vapor and hydrogen gas. Cobalt metal films were deposited on heated substrates by the reaction of alternating doses of cobalt(II) bis(N,N′-diisopropylacetamidinate) vapor and hydrogen gas. Nitrides and oxides of these metals can be formed by replacing the hydrogen with ammonia or water vapor, respectively. The films have very uniform thickness and excellent step coverage in narrow holes. Suitable applications include electrical interconnects in microelectronics and magnetoresistant layers in magnetic information storage devices.

A single source precursor for depositing ternary I-III-VI₂ chalcopyrite materials useful as semiconductors. The single source precursor has the I-III-VI₂ stoichiometry “built into” a single precursor molecular structure which degrades on heating or pyrolysis to yield the desired I-III-VI₂ ternary chalcopyrite. The single source precursors effectively degrade to yield the ternary chalcopyrite at low temperature, e.g. below 500° C., and are useful to deposit thin film ternary chalcopyrite layers via a spray CVD technique. The ternary single source precursors according to the invention can be used to provide nanocrystallite structures useful as quantum dots. A method of making the ternary single source precursors is also provided.

At least one of functionality, dimension, pore size and free volume of the IRMOF is substantially determined by the organic linking compound.

The present invention provides a solution for resource sharing (e.g., inter-Cloud) within a Cloud-computing environment. One objective of the present invention is to better utilize idle public or private Cloud infrastructures and improve the availability of Cloud services by allowing different Cloud service providers to virtually combine their services and infrastructures. In the event that there is not enough capacity for a single Cloud service provider to manage its workload, the workload may be shifted to additional infrastructures within the Cloud. The result of the workload shift may reduce the unavailability of Cloud services to the Cloud end-user by allowing another Cloud service provider to temporarily handle the workload. Based on the resource sharing activities, compensation (e.g., credits/tokens) can be exchanged between the participating Cloud providers to reflect their participation in the resource exchange.

A novel coordination complex formed by dinuclear metal complexation is provided. The complex is a dinuclear metal complex of a compound, wherein the compound comprises a conjugation ring system substituted with: a) an electron donating group selected from —OH, —SH and —NH₂; b) an indicating group selected from a chromogenic group, a fluorescent group and an electrochemical group; and c) two binding auxiliary groups, in combination with the electron donating group each of which being coordinated with the metal to provide an anion bonding site, wherein as the complex binds to a anion, the coordination of the electron donating group with the metal is weakened and electron donation of the electron donating group to the conjugation ring system is reinforced such that the reinforced electron donation by the electron donating group is transferred through the conjugation ring system to the indicating group to produce an indicating signal concomitant with the change of its electronic density. The coordination complex shows high sensitivity and high selectivity for pyrophosphate over other anions in an aqueous solvent over a wide pH range. Therefore, the complex is useful for pyrophosphate assay as a pyrophosphate sensor.
