What happens when gold and silver just don’t cut it anymore? You turn to metallic alloys, which are what Army researchers are using to develop new designer materials with a broad range of capabilities for our Soldiers.
This is exactly what scientists Dr. David Baker and Dr. Joshua McClure from the U.S. Army Research Laboratory are doing to lighten the load and enhance the power of Soldier devices used on the battlefield.
他们的研究与马里兰州大学的玛丽娜·莱特（Marina Leite）和陈·冈（Marina Leite）教授和巴西大学遗传性Paulista大学的Alexandre Rocha教授合作，最近在9月4日的《封面》上刊登高级光学材料。
研究论文“通过合金为光子学合金工程进行工程”，重点介绍通过更换合金化学成分来控制金和银合金的光学和等离子性能。
贝克说：“我们证明并表征了具有调谐光学特性的金/银合金，称为表面等离子体极化子，可用于广泛的光子应用中。”“基本努力结合了实验和理论，以解释合金的光学行为的起源。这项工作强调，金属表面的电子结构可以在更改合金的化学成分时进行设计，从而为整合到许多不同的应用中铺平了道路，在这些应用中，否则单个金属否则就无法具有正确的特性。”
该研究的重点是结合实验和理论努力，以阐明合金材料的电子结构以及对光学行为的直接影响。
根据研究人员的说法，这些材料的见解能够调整这些材料的光学色散和轻度收获能力，这些功能可以胜过由黄金等单个元素制成的系统。
“The insights of the paper are useful to Soldiers because they can be applied to a variety of applications including, but not limited to: photocatalytic reactions, sensing/detection and nanoscale laser applications,” McClure said. “When tuned properly, the integrated alloyed materials can lead to reductions in the weight of energy harvesting devices, lower power requirements for electronics and even more powerful optical sensors.”
The researchers are currently looking at other metallic alloys and anticipate that their combined experimental and computational approach may be extended to other materials, including nonmetallic systems.
“等离子使潜在parad领域igm shifting characteristics with applications to the warfighter; this includes everything from computation, to energy harvesting, to communication, and even directed energy,” Baker said. “However, researchers in these fields are limited to a handful of elements on the periodic table; gold and silver are two of the most commonly studied. This lack of options limits the available properties for technology development. By knowing the fundamental optical and electronic properties of alloys, we can develop new designer materials with a broader range of capabilities.”
对于研究人员而言，选择自己的作品在《期刊》的封面上是非常令人兴奋的个人和专业，并揭示了他们为未来士兵的成功而发展的东西。
他们指出，这种承认强调，更广泛的科学界认识到其贡献和研究方向的价值，很明显，他们的方法和合金材料变得越来越重要，并且与各种光子应用有关。
