The research objective of this award is to develop magnetically-responsive, low-melting-point metal alloys (consisting of magnetic particles in a metal matrix) that can be manipulated remotely using a magnetic field. These materials will enable the movement of metal into vertical geometries and hard-to-reach locations to create three-dimensional small-scale assemblies. With a systematic study, this program will provide an understanding of reliable methods for synthesis and the effect of dispersions on the mechanical and electrical properties as well as the wetting and viscosity behavior. Lastly, this work will also investigate various 3D geometries that can be generated with these materials and explore magnetic-induction heating conditions best suited for these alloys.If successful, the results of this research will provide an opportunity to rapidly fabricate three-dimensional metallic structures. These alloys will display enhanced mechanical strength, by dispersion hardening, for strong interconnects and allow direct heating by magnetic induction. Such materials will benefit the fabrication and packaging of small-scaled devices. In addition to this research pursuit, this program will also seek opportunities to mentor and train future scientists and will make an effort to get schoolchildren engaged in science, with a fun science lecture series called, Science Saturdays (www.sciencesaturdays.org).

该奖项的研究目标是开发具有磁响应的低熔点金属合金（由金属基体中的磁性颗粒组成），可以使用磁场进行远程操作。这些材料将使金属移动到垂直几何形状和难以到达的位置，以创建三维小规模组件。通过系统的研究，本课程将提供可靠的合成方法和分散体对机械和电气性能以及润湿和粘度行为的影响的理解。最后，这项工作还将研究用这些材料可以产生的各种3D几何形状，并探索最适合这些合金的磁感应加热条件。如果成功，这项研究的结果将为快速制造三维金属结构提供机会。这些合金将显示出增强的机械强度，通过分散硬化，强互连，并允许通过磁感应直接加热。这种材料将有利于小型设备的制造和包装。除了这项研究之外，该项目还将寻找指导和培训未来科学家的机会，并将通过名为“科学星期六”（www.sciencesaturdays.org）的有趣科学系列讲座，努力让小学生参与科学。
