  • Patent number: 9450066
    Abstract: Methods for forming a vertically movable gate field effect transistor (VMGFET) on a silicon-on-insulator (SOI) wafer are described. The methods include providing a process of making VMGFET devices without critical alignment of masks between sequential etch and diffusion steps. The oxide layer of the SOI wafer is used for a self-limiting etch stop layer and for a sacrificial layer to form an insulating layer between a gate electrode and a substrate. The proper location of the gate electrode with respect to the source and drain junctions is insured by using a silicon gate structure as a mask layer for the diffusion process for defining the source and drain junctions.

  • Patent number: 9412020
    Abstract: Most of large-scale image retrieval systems are based on Bag-of-Visual-Words model. However, traditional Bag-of-Visual-Words model does not well capture the geometric context among local features in images, which plays an important role in image retrieval. In order to fully explore geometric context of all visual words in images, efficient global geometric verification methods have been attracting lots of attention. Unfortunately, current existing global geometric verification methods are either computationally expensive to ensure real-time response. To solve the above problems, a novel geometric coding algorithm is used to encode the spatial context among local features for large scale partial duplicate image retrieval. With geometric square coding and geometric fan coding, our geometric coding scheme encodes the spatial relationships of local features into three geo-maps, which are used for global verification to remove spatially inconsistent matches.

  • Patent number: 9359214
    Abstract: By controlling the pre-treatment of biomass materials and pyrolysis conditions, silica samples with various surface areas and levels of crystallinity were synthesized. With proper treatment, biogenic silica nanoaggregate (25-30 nm in diameter) can be synthesized from biomass materials. The characterizations revealed that the silica nanoaggregates were composed of smaller primary silica nanoparticles (ca. 4.2 nm in diameter). Under controlled melting catalyzed by metal salt cations, the silica nanoaggregates may be fuse to form semi-crystalline porous silica frameworks with tunable pore size and structural integrity. Organosilicon complexes were synthesized from the bio derived silica nanoaggregates.

  • Publication number: 20140005415
    Abstract: A facile mechanochemical intercalation approach was adopted to immobilize ionic liquids into layered materials. The immobilized ionic liquids were found to be useful as catalysts for the coupling reaction of CO2 and propylene oxide to synthesize propylene carbonate. The immobilized ionic liquid exhibited similar reactivity as the free ionic liquid. Overall, the 10 mechanochemical approach proves to be effective in immobilizing ionic liquids in layered compounds and thus may expand the applications of ionic liquids and, meanwhile, improve catalyst separation and recycling.
