Catalysts based on platinum group metals have been a major focus of the chemical industry for decades. We show that plasmonic photocatalysis can transform thermally unreactive, earth-abundant transition metal into catalytically active site under illumination. Fe sites in Cu-Fe antenna-reactor complex achieve efficiencies very similar to Ru photocatalytic decomposition ammonia ultrafast pulsed When illuminated with light-emitting diodes rather than lasers, remain comparable, even when scale...
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...
Metasurfaces are a class of two-dimensional artificial resonators, creating new opportunities for strong light–matter interactions. One type nonradiative optical metasurface that enables substantial light concentration is based on quasi-Bound States in the Continuum (quasi-BIC).

By depositing Ni nanoparticle reactors onto metasurface, create antenna–reactor photocatalyst, where virtually...
Aluminum nanocrystals (AlNCs) are of increasing interest as sustainable, earth-abundant nanoparticles for visible wavelength plasmonics and versatile nanoantennas energy-efficient plasmonic photocatalysis. Here, we show that annealing AlNCs under various gases thermal conditions induces substantial, systematic changes in their surface oxide, modifying crystalline phase, morphology, density, defect type concentration. Tailoring the oxide properties enables to function all-aluminum-based...
Non-oxidative dehydrogenation of propane produces valuable propylene feedstocks and clean hydrogen fuel but, as an endothermic reaction, conventionally requires high temperatures. Here we report a photocatalyst that combines plasmonic Al@TiO2 core–shell nanoparticles with Pt single atomic active sites clusters, capable efficient into selectivity using visible light illumination. Through strong metal–support interactions, the reducible TiO2 shell layer controls nuclearity exposed species,...
Store-operated calcium release-activated (CRAC) channels mediate a variety of cellular signaling functions. The CRAC channel pore-forming protein, Orai1, is hexamer arranged with 3-fold symmetry. Despite its importance in moving Ca2+ ions into cells, detailed mechanistic understanding Orai1 activation lacking. Herein, working model proposed for the putative open state Orai from Drosophila melanogaster (dOrai), which involves "twist-to-open" gating mechanism. supported by energetic,...
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...
Conformational transitions of protein between different states are often associated with their biological functions. These dynamic processes, however, usually not easy to be well characterized by experimental measurements, mainly because inadequate temporal and spatial resolution. Meantime, sampling configuration space molecular dynamics (MD) simulations is still a challenge. Here we proposed robust two-ended data-driven accelerated (teDA2) conformational method, which drives the structural...
Foldamer, inspired by the structures and functions of biopolymers, is defined as an artificial molecular architecture that can fold into a three-dimensional structure in solution has been growing active field supramolecular chemistry. The central issue foldamer science to understand how primary sequence oligomer folds conformationally ordered well individual subunits self-associate assembly. For duplex structures, these two issues are always interrelated inseparable with each other. Although...
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".
