The invention relates to a substantially laminary manufacture comprising 2 substantially laminary layers in contact, wherein the layers comprise a woven, hydrophilic material.
Abstract:
Precisely-shaped composites and methods for making these composites are disclosed. The method of this disclosure comprises introducing a precursor composition onto a production tool having at least one continuous surface and a plurality of cavities so as to fill at least a portion of the cavities with the precursor composition and wherein the precursor composition, upon curing, forms a composition having a shape corresponding to the cavities thereby resulting in a plurality of discrete, precisely-shaped particles having a porosity comprising one of the following: (a) 10 m 2 /g or greater or (b) 5 kdalton or greater. The precisely-shaped particles have at least one essentially flat side. The precisely-shaped particles can be confined in a vessel and used for chromatographic applications.
Abstract:
A method includes injecting a material into a mold to form a molded product. The mold includes multiple layers of shaping elements extending through a cavity where each layer of shaping elements includes multiple shaping elements (e.g. pins). The method also includes removing the molded product from the mold, the molded product having a porous structure formed by at least some of the shaping elements of the layers of shaping elements. A porous structure (which may be made by the method) includes multiple ordered structural members defining the porous structure, the multiple structural members intersecting to form structural member intersections. The structure also includes multiple pores defined by the multiple structural members. A mold used to make a structure may include a relatively large number shaping elements within a small area.
Abstract:
Articles of manufacture and devices and methods of forming and using the same are provided, wherein the article comprises a porous inorganic substrate contained in or bounded by a support made from an inorganic material are provided, wherein said porous substrate and support are heated to a temperature effective to shrink the support onto the porous substrate such that liquid tight contact is formed between the porous substrate and the support. In a preferred aspect, the porous inorganic substrate has a porosity of at least 5%, and is a porous monolith formed using a sol-gel method. The articles thus formed provide a confined fluid flow through the porous substrate, providing superior performance in separations, catalysis, filtration, and the like.
Abstract:
A method of forming an agent for removing or separating a species from a diluent or process stream, e.g. a desulphurisation agent. The method comprises mixing at least one compound of manganese and pore forming articles.
Abstract:
A method of automatically isolating and purifying nucleic acid from a nucleic acid-containing specimen is provided, the method comprising: injecting a liquid into a cartridge for isolation and purification of a nucleic acid including at least two openings from one opening of the at least two openings, in which the cartridge includes a container having the at least two openings and containing a nucleic acid-adsorbent solid phase; passing the liquid through the nucleic acid-adsorbent solid phase by a pressure difference generated by a pressure generation means for generating a pressure difference between the inside and outside of the container; and discharging the liquid from the other opening of the container to the outside of the container by a pressure difference generated by the pressure generation means, wherein a pressure generated in the inside of the container by the pressure generation means is measured, a pressure change velocity and a pressure change acceleration are calculated on the basis of the value of the measured pressure, and the timing of completion of discharge of the liquid from the container is determined by use of a temporal change pattern of at least one of the measured pressure, the pressure change velocity and the pressure change acceleration.
Abstract:
The present invention is a method of producing porous beads, which comprises the steps of providing a first liquid phase comprising a bead matrix material and essentially edgy templating particle(s), said particle(s) being treated with a surface modifying agent; providing a second liquid phase which is immiscible with the first liquid phase; contacting the first phase and the second phase under conditions resulting in an emulsion of droplets comprised of the first liquid phase dispersed in the continuous second liquid phase; transforming the droplets to mesoporous beads by solidification of the liquid; and removing the templating particle(s) from the beads without causing any essential change of the surrounding bead, whereby hierarchical networks of pores are provided in the beads.
