题目:Nanomaterials and Light for Sustainability and Societal Impact 

   

摘要:  

Metallic nanoparticles, used since antiquity to impart intense, vibrant color into materials, then brought to scientific attention in the 19th century as “Faraday’s colloid”, have more recently become a central tool in the nanoscale manipulation of light. When excited by light, metallic nanoparticles undergo a coherent oscillation of their conduction electrons- known as a plasmon- which is responsible for their strong light-matter interactions and properties. While the scientific foundation of this field has been built on noble and coinage metals (most typically gold or silver), more recently we have begun to question whether the same, or similar properties can also be realized in more sustainable materials.  Aluminum, the most abundant metal on our planet, can support high-quality plasmonic properties spanning the UV-to-IR region of the spectrum. Coupling a plasmonic nanoantenna directly to catalytic nanoparticles  transforms the entire complex into an efficient light-controlled catalyst capable of driving chemical reactions under surprisingly mild, low temperature conditions. This new type of light-based catalyst can be utilized for remediating greenhouse gases, and converting them to useful molecules for industry, or benign molecules for a cleaner planet.  We have previously introduced photothermal effects for biomedical therapeutics; now, years after their initial demonstration, this approach is being utilized in human trials for the precise and highly localized ablation of cancerous regions of the prostate, eliminating the highly deleterious side effects characteristic of conventional prostate cancer therapies.  Photothermal effects can also be harvested for sustainability applications, which we have most recently demonstrated in an off-grid solar thermal desalination system that transforms membrane distillation into a scalable water purification process.  

 

Key words: Photocatalysis, photothermal cancer therapy, solar water distillation 

 

个人简介:   

Naomi Halas isa member of the National Academy of Sciences, the National Academy of Engineering, and the American Academy of Arts and Sciences. She is the Stanley C. Moore Professor in Electrical and Computer Engineering, Professor of Biomedical Engineering, Professor of Chemistry, Professor of Physics and Astronomy, and founding director of the Laboratory for Nanophotonics at Rice University. She is the Director of the Smalley-Curl Institute. 

Halas is one of the pioneering researchers in the field of plasmonics, creating the concept of the “tunable plasmon” and inventing a family of nanoparticles with resonances spanning the visible and infrared regions of the spectrum. She is author of more than 300 refereed publications, has more than fifteen issued patents, has presented more than 500 invited talks, and has been cited more than 84,000 times (over 60,000 citations and H=123 on Web of Science, over 84,000 citations and H=142 on Google Scholar).
