Abstract: A high-strength, high-toughness, weldable and deformable rare earth magnesium alloy comprised of 0.7˜1.7% of Ym, 5.5˜6.4% of Zn, 0.45˜0.8% of Zr, 0.02% or less of the total amount of impurity elements of Si, Fe, Cu and Ni, and the remainder of Mg, based on the total weight of the alloy. During smelting, Y, Ho, Er, Gd and Zr are added in a manner of Mg—Y-rich, Mg—Zr intermediate alloys into a magnesium melt; Zn is added in a manner of pure Zn, and at 690˜720° C., a round bar was cast by a semi-continuous casting or a water cooled mould, then an extrusion molding was performed at 380˜410° C. after cutting. Before the extrusion, the alloy is treated by the solid-solution treatment at 480˜510° C. for 2˜3 hours, however, the alloy can also be extrusion molded directly without the solid-solution treatment.

Abstract: A low-cost, easy to operate, three-phase tilting agitator for microarrays, including large area microarrays, provides experimentally verified improvements in hybridization intensity and uniformity. Motion is coupled from a single motor to a sample holder via three suspension tethers. The microarrays may be immersed in a water bath during agitation to maintain a temperature for the hybridization reaction. The use of traditional cover slips for the microarrays minimizes the volume requirement for target sample solution.
