  • Patent number: 9828251
    Abstract: Silica aerogels with improved properties are disclosed together with methods for synthesizing such aerogels. The improved properties include lower thermal conductivity (better insulating capacity), lower acoustic velocity, lower dielectric constant and improved ductility. Greater tunability of the refractive index can also be achieved. The silica aerogels are prepared by a sol-gel processing method that provides better control of the formation or aerogel structures. Generally speaking, the improvements arise from control of the synthesis to create a morphology of primary clusters and diverse-sized secondary clusters of dense silica aerogels separated by less densely packed regions. By providing a broader range of secondary clusters and/or pore sizes and loose connectivity between clusters, reductions can be achieved in thermal conductivity and flexural modulus.

  • Patent number: 9388081
    Abstract: The present invention relates to refractory articles in general having improved surface properties. The objective of the invention is to propose an improvement of the refractory articles comprised of a fused silica matrix which will overcome the some of the defects while keeping the excellent known properties of the fused silica matrix. This objective is reached when a sintered ceramic phase is present in the porosity of at least a portion of at least a surface of the matrix. The present invention also relates to a process for producing such an article.

  • 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.

  • Patent number: 9353271
    Abstract: A low-gloss coating composition is disclosed. The coating composition comprises a unique blend of particles, including untreated silica and organic treated silica and wax treated silica. The use of these particles in combination provides for a significant reduction in the weight percent of certain particles that can impart a suitable level of gloss to a coating. The particles can be included, for example, in a urethane acrylate binder that can be cured using UV radiation.

  • Patent number: 9206356
    Abstract: The invention provides a nanoparticle, a process, a liquid crystal display panel and a display device for inducing liquid crystal alignment in an advanced super dimension switch mode. The nanoparticle is a silicon dioxide nanoparticle modified using the organic silicon compound of Formula (I), wherein R can be the same or different and is —H or —C2H5; M contains rigid groups such as benzene ring, biphenyl, and/or cyclohexane. In the invention, the organic silicon compounds, which share similar structures with the nematic liquid crystal molecules in the ADS mode, are employed for modifying the silicon dioxide nanoparticles, facilitating the even dispersion of the modified silicon dioxide nanoparticles in liquid crystals; and the organic silicon compound contains rigid groups that can effectively induce the directional alignment of the liquid crystals, thereby helping improve the display effect of the ADS mode liquid crystal display panel.
