Plasmon-induced photocatalysis is a topic of rapidly increasing interest, due to its potential for substantially lowering reaction barriers and temperatures the selectivity chemical reactions. Of particular interest plasmonic are antenna-reactor nanoparticles nanostructures, which combine strong light-coupling nanostructures with reactors that enhance specificity. Here, we introduce Al@TiO2 core-shell nanoparticles, combining earth-abundant Al nanocrystalline cores TiO2 layers tunable...
ConspectusAluminum in its nanostructured form is generating increasing interest because of light-harvesting properties, achieved by excitation localized surface plasmon resonance. Compared to traditional plasmonic materials, the coinage metals Au and Ag, Al far more earth-abundant and, therefore, suitable for large-area applications or where cost may be an important factor. Its optical properties are flexible than either supporting resonances that range from UV wavelengths, through visible...
The field of plasmonics has largely been inspired by the properties Au and Ag nanoparticles, leading to applications in sensing, photocatalysis, nanomedicine, solar water treatment. Recently quest for new plasmonic materials focused on earth-abundant elements, where aluminum is a sustainable, low-cost potential alternative. Here we report chemical synthesis sub-50 nm diameter Al nanocrystals with plasmon-resonant absorption UV region spectrum. We observe transition from UV-resonant response,...
Methods for generating solvated electrons─free electrons in solution─have focused primarily on alkali metal ionization or high-energy photons. Here we report the generation of by exciting plasmon resonance Al nanocrystals suspended solution with visible light. Two chemical reactions were performed: a radical-addition reaction spin-trap 2-methyl-2-nitrosopropane, and model cyclization radical clock 6-bromohex-1-ene. A quantum efficiency at least ∼1.1% absorbed photon to electron can be...
Aluminum nanocrystals (Al NCs) with a well-defined size and shape combine unique plasmonic properties high earth abundance, potentially ideal for applications where sustainability cost are important factors. It has recently been shown that single-crystal Al {100} nanocubes can be synthesized by the decomposition of AlH3 Tebbe's reagent, titanium(IV) catalyst two cyclopentadienyl ligands. By systematically modifying molecular structure, control NC growth morphology is observed...
Aluminum nanocrystals created by catalyst-driven colloidal synthesis support excellent plasmonic properties, due to their high level of elemental purity, monocrystallinity, and controlled size shape. Reduction in the rate nanocrystal growth enables highly anisotropic Al nanowires, nanobars, singly twinned "nanomoustaches". Electron energy loss spectroscopy was used study properties these nanocrystals, spanning broad range needed map modes. The coupling between other metal nanostructures,...
Our null hypothesis was that a computer algorithm will not predict breast cancer patients' 10-year survival with greater accuracy than the 64.3% baseline of Surveillance Epidemiology and End Results (SEER) database [3]. The aims this study were to (1) Build an infrastructure convert SEER data into machine readable format; (2) Train Machine Learning (ML) algorithms survival; (3) Measure predictive ML algorithms. We downloaded 657,711 clinical demographic characteristics from converted them...
