Abstract: A composition includes porous silica particles to carry a cell fate modulating factor therein. A method for modulating cell fate includes treating various cells with the composition. The cell fate modulating factor is delivered to a stable target receptor, toxicity to subject cells for delivery may be reduced, a fate of the subject cells can be controlled through sustained release of at least 99 wt. % of the cell fate modulating factor.

Abstract: Provided are an all-silica zeolite separation membrane for separating carbon dioxide, etc., and not causing a decrease in the processing amount due to adsorption of water molecules, and a production method therefor. One aspect of the present invention is a zeolite separation membrane, in which the framework of a zeolite crystal structure formed on a porous support is all silica, characterized in that the zeolite crystal structure formed on the porous support is fluorine free. Another aspect of the present invention is a method for producing a zeolite separation membrane having a zeolite crystal structure on a porous support, characterized in that the method includes a step of producing a seed crystal, a step of applying the seed crystal onto the porous support, a step of producing a membrane synthesis raw material composition, and a step of immersing the porous support having the seed crystal applied thereon in the membrane synthesis raw material composition and performing hydrothermal synthesis, and the membrane synthesis raw material composition contains a silica source and an organic template and does not contain a fluorine compound.

Abstract: The invention relates to the preparation of novel bi- or tri-metallic silicate micro-porous and/or meso-porous materials based on cerium, nickel, copper and/or zinc on a porous silicate framework matrix to use its molecular sieve effect to target preferentially the acidic organic molecules present in hydrocarbon feedstocks like crude oil, bitumen, VGO and the like. The chosen metals are selected based on their ability to activate steam and transfer oxygen for completing the oxidation of carboxylic compounds or decarboxylating them. These composite materials can be prepared under hydrothermal synthesis conditions in order to produce suitable porous solids where the metals are well dispersed and preferentially distributed inside the channels of the silicate framework where they can interact only with the molecules that can go inside the channels. According to the invention, the metallo-silicate materials are prepared under hydrothermal synthesis conditions Modification of the physical-chemical properties of the porous silicate materials can be accomplished by partial replacement of the silicon atoms by cerium, nickel, copper and/or zinc atoms in the material by isomorphous substitutions of these elements in a synthesis gel or by post-synthesis modifications like ion-exchange or impregnation/deposition. The materials can be used as prepared catalysts for the steam catalytic reduction of the total acid number (TAN) in acidic crude oil feedstocks and in the presence of steam and/or CO2 as oxidizing agent to complete decarboxylation and to keep the metal oxide active sites from reducing and deactivating as well as other partial upgrading reactions.
