摘要:
A substance (for example, methylcellulose) that undergoes a reversible gel to sol phase transition is utilized in a recovery method for specific micromaterials such as DNA molecules, cells, microorganisms and the like, approximately several μm in size, from a mixture containing other micromaterials, and a micromaterial is accurately and conveniently recovered. The present invention is a method of recovering a desired micromaterial in a system comprising a medium that undergoes a reversible phase transition between a sol and a gel, a support material and micromaterials, comprising the steps of converting the medium surrounding the micromaterial to be recovered into a gel locally to immobilize said micromaterial on said support along with the gelled medium, removing the medium and micromaterials not immobilized on said support material and converting the gelled medium to a sol to recover the micromaterial.

摘要:
An ink containing a hydrophobic colloid charged with a positive zeta potential when the pH of the ink is within a range of over 4 and under 6. Silicon or silicon compound can be limited from being eluted into the ink from a circuit board formed from a silicon wafer or the like. Additionally, silicon or silicon compound, if eluted into the ink can be prevented from being deposited on a resistance heater and causing “cogation”, or to prevent the silicon or silicon compound from being deposited in an ink channel and nozzle to clog the nozzle.

A method of forming a pattern and a method of producing an electronic element are characterized by including a first step of forming an electrically conductive film (D) by applying a liquid composition onto a first plate (10), and heating the first plate (10); a second step of forming an electrically conductive pattern (D′) on the first plate (10) by pressing a second plate (20) having a projection-and-recess pattern on a surface side thereof onto a surface side of the first plate (10), on which the electrically conductive film (D) is formed, to transfer an unwanted pattern of the electrically conductive film (D) to top faces of projections (20a) of the second plate (20), thereby removing the unwanted pattern; and a third step of transferring the electrically conductive pattern (D′) to a surface of a transfer-receiving substrate (30) by pressing the surface side of the first plate (10), on which the electrically conductive pattern (D′) is formed, onto the surface of the transfer-receiving substrate (30), wherein the liquid composition contains a solvent having a vapor pressure of 133 Pa or less at a surface temperature of the heated first plate (10). These methods provide a method of forming a pattern and a method of producing an electronic element in which a state of a liquid-composition coating film is stabilized and a fine and precise pattern can be stably formed with good reproducibility.
摘要:
It is possible to observe a state of stress applied to a region around a cavity replicating a body cavity such as a blood vessel and the like in a three-dimensional model. In catheter insert simulation, when stress is applied to the region around the cavity in the three-dimensional model, it is possible to observe the catheter state together with a photoelastic effect corresponding to the stress state in the surrounding region caused by the catheter.
