    摘要： An apparatus for measuring a methanol concentration is provided. The apparatus is located in a pipe which supplies liquid fuel to the anode of a direct liquid feed fuel cell, and may include a vertical supporting beam located in the pipe; a horizontal plate located on the supporting beam and having an upper surface with a predetermined roughness; and a sensor fixed to a side of the supporting beam, which generates an electrical signal through a transformation of the supporting beam resulting from variations in a viscosity of the liquid fuel running through the pipe.

    摘要： A device and a method for printing biomolecules onto a substrate using an electrohydrodynamic (EHD) effect are provided. The device for printing biomolecules onto a substrate using an electrohydrodynamic (EHD) effect includes at least one capillary having an outlet through which a feeding solution of biomolecules selected from the group consisting of nucleic acids, proteins, and oligopeptides is discharged, the nucleic acids being selected from the group consisting of probe DNA, RNA, peptide nucleic acid (PNA), and LNA and the proteins being selected from the group consisting of antigen and antibody; a printer body supporting the at least one capillary; a substrate below the outlet having a target surface onto which the biomolecules are deposited; a first electric field forming electrode located on the printer body around the circumference of the outlet; a second electric field forming electrode spaced apart from the first electrode by a predetermined distance; and a voltage applying unit which is electrically connected to the first electrode and the second electrode to apply an alternating current (AC) voltage between the first electrode and the second electrode so that an electric field may be formed around the biomolecule solution suspended in the outlet, and due to the interaction of the electric field and a difference in dielectric constant between the biomolecule solution having a free surface and the surrounding atmosphere, the electric force acts inward on the biomolecule solution from the surroundings, thereby dropping a predetermined amount of the biomolecule solution onto the target surface of the substrate. By using an EHD effect, the advantages of the device and method are that the process is quick, the biomolecule spots are uniform and easily aligned, and especially it is possible to spot the biomolecules correctly and reproducibly even when the printer body is not fully aligned with the substrate. In addition, the device and method are applicable to proteins which are sensitive to heat and biomolecules which have neutral charges.
