摘要:This invention relates to bifunctional catalyst formulation for synthesis of dimethyl-ether (DME) from waste carbon dioxide (CO₂) and hydrogen (H₂) and the preparation method of this catalyst formulation. In the preparation method, aluminum oxide-silicon dioxide-copper oxide (Al₂O₃-SiO₂-CuO) catalyst mixture formulation is obtained by using the sol-gel method. The catalysts that are the subject of the invention are bifunctional and perform the synthesis of DME from CO₂ and H₂ in a single-step without forming unwanted byproduct of CH₄, and thus, the synthesis of DME can be done much simply and economically. In addition to this, the sol-gel method in the current invention yields the controlled crystallite size of the active component in the catalysts; thus, the active site loss problem due to uncontrolled growth of crystal sizes that occurs in traditional preparation methods is prevented. The catalyst mixture formulation weight percentages are 10%-90% Al2O₃, 10%-90% SiO₂ and 10%-90% CuO.

摘要:The present disclosure relates to a process for synthesis of mesotrione. The process comprises reacting 4-toluene sulfonyl chloride with alkali metal sulphite and alkali metal bicarbonate to obtain alkali metal toluene-4-sulfinate. The alkali metal toluene-4-sulfinate is reacted with alkali metal salt of monochloroacetic acid to obtain 4-methylsulfonyl toluene. Further, 4-methylsulfonyl toluene is nitrated to obtain 2-nitro-4-methylsulfonyl toluene. 2-nitro-4-methylsulfonyl toluene is oxidized and then halogenated to obtain 2-nitro-4-methylsulfonylbenzoyl halide. 2-nitro-4-methylsulfonylbenzoyl halide is reacted with alkali metal salt of 1,3-cyclohexanedione to obtain 3-(2-Nitro-4-methylsulfonylbenzoyloxy)cyclohexen-1-one which is reacted with base, a third fluid medium and cyanide ion source to obtain an amorphous mesotrione. The present disclosure also discloses the steps of converting the amorphous mesotrione to crystalline mesotrione having purity greater than 99%. The process of the present disclosure for preparing mesotrione is rapid, economic, and environment friendly.

标题:Synthesis of inverted titania photonic crystal
发明人：EXIR JULIA
摘要:A novel method was devised to synthesis an inverted titania crystal on a substrate. At first, a film of surfactant sodium dodecylsulfate (SDS) polystyrene spherical particles was grown on a substrate using Colvin method. Surfactant sodium dodecylsulfate (SDS) stabilizes polystyrene particles and induces necking between the polystyrene particles. Next, the film was dropped inside a Falcon tube that half-filled with a solution comprising Titanium Isopropoxide (TiPT) or Titanium ethoxide (TEOT) diluted with anhydrous ethanol. Then, the Falcon tube was rotated in a centrifuge machine set at 1200-3600 rpm. After 30 minutes the film was removed from the tube and placed inside an anti-static plastic container. The film was stored inside the container for at least 6 hours. This was repeated many times depending on the dilution of the precursor solution (the more diluted the precursor the more the repetition) to fill up voids among the polystyrene colloidal particles. At last, the film was placed inside a tube furnace under airflow with a predetermined ramping temperature setting to remove the polystyrene template and to crystallize titania to its anatase or rutile form. At this stage titania is transformed into a crystalline form. The result of this method is a stable and well-structured inverted titania photonic crystal on a substrate.

摘要:Manufacturing and purification processes of proteins, KH 1-through KH-52, and more KH proteins are being discovered in good healthy cells—named KH CELLS. KH CELLS are good healthy cells in which the RNA synthesizes good proteins that: 1) Send signal to the damaged, sick, and bad cells that triggers that synthesis of good proteins that transform these cells to become GOOD healthy cells; 2) Send signal to the other currently undamaged cells to synthesis of good proteins to protect them from being damaged, infected and prone to DNA and other cellular alterations; and 3) Send signal to the body to produce new cells that are healthy and forbid them from being affected by intra- and extracellular damaging signals. The mechanism that governs these processes is that the KH good healthy cells provide innate good signals that make good proteins to boost the immune system.
