Light is energy. Sunlight can be harnessed by solar cells, for instance, turning light into electricity, which can, in turn, be used to power big and small devices. This is, however, a rather inefficient process and light can be used differently for various applications. One way to efficiently use light is through a photothermal material, which converts light into heat. Heat is an important user of fossil fuels: industrial processes for instance consume vast quantities of fossil fuels. It has been reported that 4.2% of worldwide delivered energy is consumed manufacturing basic inorganic, organic, and agricultural chemicals. Of this 17 quadrillion Btu, 78% comes from liquid fuels, natural gas, and coal, leading to greenhouse gas emissions. [1] A substantial fraction of these fuels are used to heat up chemical reactions, while free, green, and abundant sunshine could instead provide the required energy via a photothermal material.Heat also heals: photothermal materials injected near cancer cells can be excited by an otherwise non-interacting infrared light, leading to local temperature rise (of the order of 10s of degrees) sufficient to kill cancer cells without any surgery or chemotherapy. This proposal targets the development of a new class of biocompatible photothermal material based on the 8th most abundant element in earth's crust, magnesium. We have shown previously that small particles of magnesium are stable in air and interact strongly with light. Magnesium, like gold and silver, is extraordinarily good at absorbing light because its interaction is different than that of simple "black" materials. Indeed, these nanoparticles act like antenna for light and consequently absorb more light than their physical footprint. This phenomenon is truly nanoscale; it involves the light-driven oscillation of electrons in small metallic particles and is called localized surface plasmon resonance.In the two years of this project, we first aim to develop ways to make large quantities of magnesium nanostructures, suitable for industrial-scale production. We will then demonstrate their ability to efficiently produce heat from light, and will study how to best match the particle size to the specific application, for both sunlight-matched and medical applications. At the end of the project, we will be in a position to approach industrial partners to discuss further development and commercialization of these new green technologies.[1] Energy Information Administration, Government Publications Office, International Energy Outlook: 2016 with Projections to 2040.

光是能量。例如，太阳能电池可以利用阳光，例如将光转换为电能，而电池可以将光线转化为大小设备的动力。但是，这是一个相当低效率的过程，并且光可以用于各种应用程序。有效使用光线的一种方法是通过光热材料，将光转化为热量。热量是化石燃料的重要用户：例如，工业过程消耗大量化石燃料。据报道，4.2％的全球传递能源是消耗基本无机，有机和农业化学品的制造业。在这17个四亿BTU中，有78％来自液态燃料，天然气和煤炭，导致温室气体排放。 [1]这些燃料的很大一部分用于加热化学反应，而自由，绿色和丰富的阳光可以通过光热材料提供所需的能量。还可以愈合：在癌细胞附近注射的光热材料可以通过原本非冲突的红外光线激发，而不是局部温度升高，导致10s的疗效（不足10s的癌症），或者不足以杀死癌症）杀死了癌症）杀死了杀伤量）。该提案针对的是基于地壳中第八大元素的新型生物相容性光热材料的开发。我们先前已经证明，镁的小颗粒在空气中稳定，并与光线相互作用。镁，例如黄金和银色，在吸收光方面非常擅长，因为它的相互作用与简单的“黑色”材料不同。实际上，这些纳米颗粒的作用像天线，因此比其物理足迹吸收更多的光。这种现象确实是纳米级。它涉及小型金属颗粒中电子的轻驱动振荡，称为局部表面等离子体共振。在该项目的两年中，我们首先旨在开发方法来制作大量镁纳米结构，适合于工业尺度生产。然后，我们将证明它们有效地从光中产生热量的能力，并将研究如何将粒度最佳地匹配到阳光匹配和医疗应用的特定应用。在项目结束时，我们将有能力与工业伙伴联系，讨论这些新的绿色技术的进一步发展和商业化。[1]能源信息管理局，政府出版社，国际能源展望：2016年预测到2040年。美国政府印刷办公室：2016年。
