摘要： Tracers for oil recovery, particularly fluorescent nanotracers conservative in aqueous phases. The tracer comprises a core-shell nanoparticle tailored according to the operation to be traced. It contains a fluorescent core that allows the detection thereof in the field and a functionalized polymeric shell that provides increased stability in high salinity aqueous phases. A method for preparing said nanotracer. Given the nanotracer versatility, it can be used both for tracing fracking steps as well as meshes of secondary and tertiary recovery.

摘要： The present invention relates to a silica aerogel blanket for ultra-high temperature, a method for producing the same, and a method for constructing the same. More specifically, the present invention provides a method for producing a silica aerogel blanket, the method capable of suppressing the generation of a bad odor during construction by including a step of heat treatment after producing a hydrophobic silica aerogel blanket so as to remove a volatile organic compound (VOC), a silica aerogel blanket produced thereby, and a method for constructing a silica aerogel blanket for ultra-high temperature, the method capable of suppressing the generation of a bad odor during the construction of the silica aerogel blanket produced by the above-mentioned production method on an ultra-high temperature piping equipment, and at the same time, preventing the loss of heat insulation performance due to moisture in the air.

摘要： A subject of this invention is to provide a dispersion liquid of a silica-based composite particle, which can rapidly polish silica film, Si wafer or even hard-to-process material, can concurrently achieve high surface accuracy (less scratches, etc.), and can suitably be used for surface polishing of semiconductor devices including semiconductor substrate and wiring board, by virtue of its impurity-free nature. The subject is solved by a dispersion liquid of a silica-based composite particle that contains a silica-based composite particle that has a core particle mainly composed of amorphous silica, and bound thereto a ceria particle mainly composed of crystalline ceria, further has a silica film that covers them.

摘要： The invention relates to a method of making hybrid organic-inorganic core-shell nano-particles, comprising the steps of a) providing colloidal organic particles comprising a synthetic polyampholyte as a template; b) adding at least one inorganic oxide precursor; and c) forming a shell layer from the precursor on the template to result in core-shell nano-particles. With this method it is possible to make colloidal organic template particles having an average particle size in the range of 10 to 300 nm; which size can be controlled by the comonomer composition of the polyampholyte, and/or by selecting dispersion conditions.The invention also relates to organic-inorganic or hollow-inorganic core-shell nano-particles obtained with this method, to compositions comprising such nano-particles, to different uses of said nano-particles and compositions, and to products comprising or made from said nano-particles and compositions, including anti-reflective coatings and composite materials.

摘要： The invention provides a process for forming a layered nanoparticle, comprising providing a suspension comprising a core particle in a first liquid, adding a second liquid to the suspension, and adding a reagent, or a precursor for the reagent, to the suspension. The second liquid is immiscible with the first liquid. If the reagent is added to the suspension, the reagent reacts to form a layer on the core particle to form the layered nanoparticle. If a precursor for the reagent is added to the suspension, the precursor is converted to the reagent, and the reagent reacts to form a layer on the core particle to form the layered nanoparticle.
