Title: Synthesis of colloidal nanocrystals
Inventor: PENG XIAOGANG
IPC: C01B19/00
Filed: 2001-10-04
Abstract: A method of synthesizing colloidal nanocrystals is disclosed using metal oxides or metal salts as a precursor. The metal oxides or metal salts are combined with a ligand and then heated in combination with a coordinating solvent. Upon heating, the metal oxides or salts are converted to stable soluble metal complexes. The metal complexes are formed by cationic species combining with the ligands and/or with the coordinating solvent. Finally, an  elemental chalcogenic precursor, for example, Se, Te, or S, is introduced in to the soluble metal complex to complete the formation of the nanocrystals at a  controllable rate. High-quality CdSe, CdTe, and CdS nanocrystals are produce d when CdO is used as the cadmium precursor. With the present method, the size , size distribution, and shape (dots or rods) of the resulting nanocrystals ca n be controlled during growth. For example, the resulting nanocrystals are nearly monodisperse without any size separation. Further, the method represents a major step towards a green chemistry approach for synthesizing high-quality semiconductor nanocrystals.

Title: Method and system for remote software distribution and installation
Inventor: HEINRICH UWE
IPC: G06F8/61
Filed: 2001-12-06
Abstract: For the remote distribution/installation of computer programs from a source to a number of target computers, the computer programs are transferred as packages. Attempt numbers for retrying a push mode and a pull mode distribution are pre-specified. A next package is identified and if a target computer is available then installation of the package on the target computer is started. Otherwise, if at least one push mode attempt is left, a next push mode is resumed and rescheduled and, if no push mode attempt is left, but at least one pull mode attempt is left, a next pull mode distribution is resumed and rescheduled. The mechanism particularly proposes a queue manager that activates a request i.e. moves the request from a request queue into an active queue and has implemented throttling that balances the load during a software distribution/installation.
