摘要： Organic-inorganic composites were prepared as colloidal particles of a cross-linked, thermally responsive polymer. Hybrid PNIPAM-polysiloxane particles and composite polymeric particles with embedded nanoparticles of an inorganic metal-oxide (MOx) such as CeO2 and TiO2 were formed. To promote the incorporation of unaggregated nanoparticles, temperature responsive microspherical gels (microgels) of N-isopropylacrylamide (NIPAM) with interpenetrating (IP) linear chains of poly(acrylic acid) (PAA) were used. The organic-inorganic composition of the hybrid polymer network was controlled by changing the time for condensation and hydrolysis of the siloxane monomer during synthesis. Experimental results indicated that the planarization of silicon oxide wafers using these hybrid particles and composites exhibited lower topographical variations and surface roughness as compared to slurries consisting of only silica or ceria nanoparticles while achieving similar removal rates and better or similar frictional characteristics.

摘要： Microcomposites comprising titanium dioxide (TiO2) nanoparticles embedded within cross-linked, thermally responsive microgels of poly(N-isopropylacrylamide) are disclosed. Interpenetrating linear chains of poly(acrylic acid) functionalize the nanoparticles for dispersal within the microgel framework. The microcomposites show rapid sedimentation, which is useful for gravity separation applications such as environmental remediation via photocatalytic degradation.The extent of loading of the TiO2 within the colloidal particles can be easily manipulated from 10% (weight) to a value as high as 75%. The microgel-titania composites showed rapid sedimentation, which is useful for gravity separation of these particles in photocatalytic applications. The settling of the microgel-titania composites occurred over minutes and was much faster than solid, impermeable spheres. As the content of TiO2 increased within the particles from 10% to 75%, the increased effective particle density led to significant decrease in the settling time from approximately 2200 seconds to approximately 100 seconds.

摘要： A logical unit number (LUN) cloning technique separates data blocks referenced by a writable virtual disk (vdisk) from data blocks referenced only by a backing store to conserve storage resources of a storage system. The LUN cloning technique separates the writable vdisk data blocks from the backing store during periods of reduced processing activity and in a manner that does not interfere with storage service provided by the system.

摘要： A system and method are provided for controlling multiple computer platforms. The method can include the operation of storing command line tasks in a database. Other command line task information can include a command name, related parameters, and a platform type for which the command line tasks are executable. A command line task can be selected from the database of command line tasks by a user for application to computing systems. A further operation is identifying at least one computing system that can be addressed from a host system and which has the same platform type as the selected command line task. The user can then select at least one computing system from a list of the identified computing systems to which the selected command line is applicable. Another operation is applying the selected command line tasks to the selected computing systems which are of a correct platform type.

摘要： A call is established between a user at a mobile device and a contact logged into a communication service through a computer application. A user selects a contact through a page displayed on a mobile device. The contact may be an email address, a messaging username, or some other contact other than a phone number. A call registration record with the contact data is generated at a network server. The mobile device places a call to a VoIP system, the VoIP system receives the call, retrieves the call registration record and establishes an audio connection between the cell phone and the computer application through which the contact is logged into the communication service. The audio connection is a hybrid connection consisting of a mobile device voice connection between the caller's cell phone and a gateway system and a VoIP connection between a computer and the gateway system.

摘要： A polarization-modulation scanning laser microscope includes a conventional laser scanning microscope, which has been improved by addition of: a polarization state generator; a polarization state analyzer; a photo-detector for receiving laser light transmitted though a sample; a signal demodulator providing two signals in response to the transmitted laser light, one of the signals being indicative of polarization orientation, and the other signal being indicative of magnitude of the transmitted polarized light. A relay interface toggles between the two signals provided by the signal demodulator and at least one other signal provided either by the photodiode of the laser scanning microscope, or by an external optical beam induced current, or both. A signal processing unit provides an image output to a display device.
