Abstract: Ultrafine metal oxide and mixed metal oxide ceramic particles are prepared by flame spray pyrolysis of a ceramic precursor solution containing one or more gycolato polymetallooxanes dissolved in a volatile organic solvent. Recycle of the nanosized particles disposed in additional ceramic precursor solution leads to larger particles. The metal oxide and mixed metal oxide particles may be converted to the respective nitrides by high temperature ammonolysis. The process produces high quality ceramic particles from inexpensive and relatively non-toxic reagents in high space-time yield.

Abstract: A method and apparatus for transmitting files on a network are described. In response to a network request for a file stored on a secondary data storage device such as a hard disk, a file server retrieves and transmits the file using a reduced number of calls from user-mode processes to kernel-mode processes.In response to a file request from a non-local networked machine, a user-mode process on the file server issues a command to a kernel-mode process requesting transmission of the requested file to the non-local networked machine via a designated connection. In response, the requested file is retrieved from the secondary data storage device and placed in kernel-mode accessed memory (e.g., cache memory). After the requested file information is stored in the kernel-mode accessed memory, a kernel-mode data transmission procedure transmits the requested file information directly from the kernel-mode accessed memory.
