"From Faraday to tomorrow: light-based applications for gold nanoparticles"
: nano-optics and plasmonics; applications in biomedicine, chemical sensing, optoelectronics
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 pursues fundamental studies of coupled plasmonic systems as well as applications of plasmonics in biomedicine, optoelectronics, chemical sensing, photocatalysis, and most recently in solar energy and sustainability, with ‘solar steam’ technology. She is co-founder of Nanospectra Biosciences, a Houston-based company developing photothermal therapies for cancer and other diseases based on her nanoparticles, currently in multiple clinical trials, and is currently transferring other technologies from her laboratory.

“Gold-complexes for the synthesis of bioactive compounds”
: gold complex synthesis, homogeneous catalysis and synthesis organic and biomolecules
The most important contributions of his group have been in the area of homogeneous gold catalysis, where they have established the basis for the mechanistic understanding of the reactions of alkynes with alkenes that have guided the discovery of many new transformations, which have been applied in the context of the total synthesis of biologically relevant natural products and molecules of interest in material science. His group has also introduced new gold catalysts that are used routinely by many research groups.

"Heterogeneous Catalysis by Gold: from nanoparticles to single-atom catalysts"
: Nanoscale Gold Catalysts, Fuel Processing for Hydrogen production, Single Atom Catalysts for Selective Hydrogenation and Oxidation Reactions
Prof. Maria. Flytzani-Stephanopoulos directs the Nano Catalysis and Energy Laboratory at Tufts University, which focuses on the design, synthesis, and mechanistic investigations of heterogeneous catalysts from nanoparticles to the single atom limit. Tailoring catalyst designs to improve both activity and selectivity translates into energy- and cost-efficient processes. Pioneering work from her lab has demonstrated the use of single atom monometallic catalysts and single atom alloys for a number of selective oxidation and hydrogenation reactions. With due attention to active site stability, these findings may lead to industrial catalysts with efficient and sustainable use of precious metals, improved product yields and reduced carbon footprint.

“From gold nuggets to "invisible" gold: how the coordination chemistry of gold demonstrates its diversity in geological systems”
mineralogy, mineral resources and sustainable development, structure-property relationships in materials, solid-state spectroscopy
His scientific activities concentrate on integrating spectroscopic and structural methods to understand disordered materials, including structure-property relationships in natural minerals and synthetic materials. The outcome concerns the crystal chemistry of minor elements in minerals, the structure and properties of glasses, radiation damage and radiogenic waste, and environmental mineralogy. Additional expertise concerns mineral resources and sustainable development.
