Based on ANSYS Workbench 3D modeling, we carried on finite element analysis to tool, and used the method of goal driven optimization to optimize the rotary tool. The optimization proves that the optimized maximum equivalent stress is 544.14 MPa, the quality is less, and the optimized rotary tool size is more reasonable. So it provided reasonable and scientific reference frame to the structural design of rotary tool.展开更多

Although persamplecosts have dramatically decreased, the total budget for such massive genome sequencing constitutes a significantbarrier for poorly funded labs. The costly lab tools required for genomics experiments further hinder such studies. Here, weshare two strategies for extensively reducing the costs of massive genomics experiments, including miniaturization of theNEBNext Ultra II FS DNA Library Prep Kit for Illumina (reducing the per-sample total costs to ~ 1/6 of that charged byservice providers) and in-lab 3D model-designing of genomics tools. These strategies not only dramatically release fundingpressure for labs, but also provide students with additional training in hands-on genomics and 3D-model-designing skills,demonstrating the high potential for their application in genomics experiments and science education.展开更多
