  • Patent number: 11214525
    Abstract: A water-based mixture of multi compounds for adding to fresh concrete to protect the concrete against moisture and moisture-associated problems. A hygroscopic and hydrophilic behavior of its crystallization system within a concrete matrix minimizes moisture transmission through capillaries and connected voids. As a result, the mixture may reduce moisture related problems, such as damage caused by repeated freeze and thaw cycles and chloride ion penetration as from deicing salts, as well as alkali-silica reactions, and other problems.

In some embodiments, a filter media may comprise two or more layers designed to enhance fluid separation efficiency. One or more of the layers may have at least a portion of a surface that is modified to alter and/or enhance the wettability of the surface with respect to a particular fluid. In certain embodiments involving a filter media including more than one surface modified layer, at least one surface modified layer may have a greater air permeability and/or mean flow pore size than that of another surface modified layer. Such a configuration of layers may result in the media having enhanced fluid separation properties compared to filter media that do not include such modified layers or configuration of layers, all other factors being equal. The filter media may be well-suited for a variety of applications, including filtering fuel, air, and lube oil.

  • Publication number: 20150037531
    Abstract: Porous aluminum-containing ceramic bodies are treated to form acicular mullite crystals onto the surfaces of their pores. The crystalsare formed by contacting the body with a fluorine-containing gas or a source of both fluorine and silicon atoms to form fluorotopaz at the surface of the pores, and then decomposing the fluorotopaz to form acicular mullite crystals. This process allows the surface area of the ceramic body to be increased significantly while retaining the geometry (size, shape, general pore structure) of the starting body. The higher surface area makes the body more efficient as a particulate filter and also allows for easier introduction of catalytic materials.

    Abstract: Methods of forming gapfill silicon-containing layers are described. The methods may include providing or forming a silicon-and-hydrogen-containing layer on a patterned substrate. The methods include non-thermally treating the silicon-and-hydrogen-containing layer at low substrate temperature to increase the concentration of Si—Si bonds while the silicon-and-hydrogen-containing layer remains soft. The flaccid layer is able to adjust to the departure of hydrogen from the film and retain a high density without developing a stress. Film qualify is further improved by then inserting O between Si—Si bonds to expand the film in the trenches thereby converting the silicon-and-hydrogen-containing layer to a silicon-and-oxygen-containing layer.

  • Publication number: 20140154441
    Abstract: The present invention solves numerous problems in state-of-the-art industrial anti-corrosion protection by using a reactive silicon oxide precursor solution. Among the problems solved are those of decreased heat transfer over a protected surface, limited protection against high-temperature corrosive fluids and difficulties in protecting complex 3D geometries and surfaces with a high surface roughness. The present invention furthermore provides an easy way of making chemical surface functionalization using e.g. silane chemistry. The invention solves these problems by coating the surface of a ceramic or metallic part with a thin layer of a liquid solution of a reactive silicon oxide precursor (rSiO-p) such as Hydrogen Silsesquioxane (HSQ) in Methyl Isobytul Ketone (MIBK) or volatile methyl siloxane (VMS), heating the part to a curing temperature of the rSiO-p, and after a curing time the reactive silicon oxide precursor is transformed into a thin layer of essentially pin-hole free silicon oxide.

  • Patent number: 8741432
    Abstract: Coated particles comprise a core of fumed or precipitated inorganic metal oxide having a surface area of about 50 to about 500 square meters per gram and a shell consisting of an array of fluoroalkyl molecular chains at a density of at least 1 chain per square nanometer, joined to the core by covalent chemical bonds and with a total organic content of at least 9.9 percent by weight. These particles are formed by the chemical attachment of fluoroalkyl-alkylsilanes after exposure to an alkylamine and followed by an extraction to remove any organic material not covalently bound. The dense packing of molecular chains in the fluoroalkyl shell combined with a mesoporous structure imparts a very low surface energy, a very high specific surface area, and surface texture over a wide range of length scales. Such features are highly desirable for the creation of, for example, superhydrophobic and superoleophobic surfaces, separation media, and release films.

  • Publication number: 20140109794
    Abstract: A protective treatment for silicide coated materials and objects, including heating elements so treated, which may be used to improve the electrical stability, oxidation resistance, energy efficiency and performance is disclosed as well as improved silicide materials. Use is made of Al—O type compounds and silicides to treat heating elements in a manner which improves their electrical stability during use. The treatment may consist of a colloidal alumina in slurry form applied to materials and objects. The resultant heating element may be used to conserve energy during its life-cycle because of the use of lower power. It is envisioned that materials other than silicide coated ones may treated in a like manner.

  • Patent number: 8679227
    Abstract: The present invention provides methods for making improved zeolite and crystalline silicoaluminophosphate (SAPO) membranes, in particular SAPO-34 membranes, on a porous support through improved removal of the organic structure-directing templating agent. A calcining step is performed in an oxygen free atmosphere, such as under a vacuum or inert gas, to remove the organic templating agent. By removing the templating agent in the absence of oxygen, the calcination step can remove a greater amount of the templating agent than comparable template removal steps conducted in the presence of oxygen and the calcination step can be conducted at significantly lower temperatures. The membranes of the present invention provide increased permeance while maintaining comparable selectivity for gas separations, particularly carbon dioxide (CO2) and methane (CH4) separations and separations at high temperatures.

    Abstract: Low k dielectric films/layers can be produced by cross-linking oligomers made from cyclic carbosilane monomers. The films may exhibit high porosity and strong resistance to chemical attack while also exhibiting improved hydrophobicity. Oligomers may be cross-linked in situ after coating on a substrate such as a silicon wafer. Resulting cross-linked layers may be further treated to improve chemical resistance and reduce water uptake.
