摘要： A filter for filtering nucleated cells that includes a body containing at least either a metal or a metal oxide as its main component; and plural through holes, each of which have a shape other than a square shape, formed therein. An arithmetic average roughness of a first side of the filter part is smaller than a size of a nucleus of the nucleated cells to be filtered.

摘要： A filter device that includes: a film section having multiple through-holes and a frame section surrounding a periphery of the film section; and a holding unit in a round or angular tubular shape, the holding unit having a groove on an inner wall of the holding unit that is constructed to hold the frame section of the filter. a size of the groove in an extending direction of the holding unit is larger than a thickness of the filter. A diameter of a first inscribed circle which contacts a surface of a recessed portion of the groove is larger than a second diameter of an inscribed circle which contacts an outer periphery of the filter.

摘要： A fabrication method for a water-absorbent filter includes obtaining a homogenized tragacanth suspension by dissolving tragacanth in a solvent, where the solvent may include distilled water, ethyl acetate, acetic acid, and formic acid, obtaining a support layer by coating a stainless steel mesh with a thin layer of a hydrophobic polymer, coating a stainless steel mesh with the thin layer of the hydrophobic polymer comprising electrospinning a hydrophobic polymer solution onto the stainless steel mesh, forming a tragacanth nanofibrous web on the support layer by electrospinning the homogenized tragacanth suspension onto the support layer, and cross-linking the tragacanth nanofibrous web by exposing the tragacanth nanofibrous web to a saturated vapor of a cross-linking agent.

摘要： A multi-layered replaceable filter assembly (100) and a microfilter assembly (200) for providing safety from external exposure. The multi-layered micro filter assembly includes plurality of filter membranes. A first filter membrane (104) prevents particles greater than 10 micron from entering the multi-layered replaceable filter assembly (100). A second filter membrane (106) has embedded activated carbon that destroys micro-organisms including viruses and bacteria. As we go further downstream, the fiber density per cm keeps increasing with the filter membranes. A fifth filter membrane (112) made up of a combination of crabyon fiber and electro-spun nano fibers provides comfort and anti-allergic effect. A sixth filter membrane (114) lowers the velocity of air that occurs from breathing and a method thereof.

摘要： The invention relates to a high-pressure hydraulic fluid screening element (1) for inserting into a hydraulic line or into a hydraulic connection of a hydraulic device, having an annular main body (2), which is aligned with respect to its axis of rotation (9) in a longitudinal direction (5). The outside diameter of the main body (2) is greater than its axial length. The inner cross section of the main body (2) is covered over by a screening region (3), which is provided with a multiplicity of apertures (4). In this case, the main body (2) and the screening region (3) are produced integrally by the powder injection-molding process.

摘要： A ventilation register includes a panel having a flange and a plurality of first apertures adapted to allow airflow through the panel, with each first aperture having a diameter or dimensions sufficient to allow movement of an object or entity through that first aperture. A filter is coupled to the ventilation register and has a plurality of second apertures adapted to allow airflow through the filter while inhibiting a movement of an object or entity through the filter.

摘要： A filter includes a plurality of first through holes which are periodically formed. At least one of the plurality of first through holes is divided by a plurality of second through holes that are smaller than the first through holes. With such a configuration, the cell aggregate having the desired size can be easily sampled.

摘要： The filter for gel shearing and particle filtration of molten polymer has a first layer of metal fibers of an average equivalent diameter between 8 and 65 μm. The cross-section of the metal fibers has two neighboring straight sides with an included angle of less than 90° and one or more irregularly shaped curved sides. The metal fibers have an average length of at least 6 mm. The metal fibers are bonded to each other by metal bonds; where the metal of the metal fibers of the first layer is the bonding agent forming the metal bonds. The filter has a second layer of metal fibers. The average equivalent diameter of the metal fibers of the second layer is smaller than the average equivalent diameter of the metal fibers of the first layer.

摘要： This disclosure describes systems, methods, and devices for phytochemical extraction. One example extraction system includes two solvent columns, a material column, and a dewaxing column. The solvent columns store and provide solvent for stripping target chemicals from plant material in the material column. The solvent mixed with target chemicals passes into the dewaxing column, where the target chemicals are separated from waxes and lipids. Cooling is applied to elements of the system by way of an open-loop CO2 refrigeration method. Solvent is moved from the solvent columns to the material column by creating a pressure differential between the two solvent columns.
