Nanostructured forms of stoichiometric In2O3 are proving to be efficacious catalysts for the gas-phase hydrogenation CO2. These conversions can facilitated using either heat or light; however, until now, limited optical absorption intensity evidenced by pale-yellow color has prevented use both together. To take advantage and light content solar energy, it would advantageous make indium oxide black. Herein, we present a synthetic route tune pitch black controlling its degree...
Abstract Raman spectroscopy's capability to provide meaningful composition predictions is heavily reliant on a preprocessing step remove insignificant spectral variation. This crucial in biofluid analysis. Widespread adoption of diagnostics using requires robust model that can withstand routine spectra discrepancies due unavoidable variations such as age, diet, and medical background. A wealth methods are available, it often up trial‐and‐error or user experience select the method gives best...
Abstract An approach to significantly enhance spontaneous Raman sensitivity through the formation of a thin film via thermophoresis along with evaporation at facet hollow‐core photonic crystal fiber is reported for first time. Sensitivity detection increased by more than 6 orders magnitude both organic and inorganic nanoparticles, facilitating search trace analytes in solution. Detection two alumina polystyrene, demonstrated down 392 nM without use surface‐enhanced spectroscopy or other...
We demonstrate novel instrumentation for spontaneous Raman spectroscopy in biofluids, enabling development of a portable, automated, reliable diagnostics technique requiring minimal operator expertise to quantify disease markers. Label-free analysis biofluids at physiologically-relevant sensitivities is achieved using microfluidic-embedded liquid-core-waveguide augmented with unique circulation approach: thermal damage and spectrum variance minimized, eliminating conventional limits on...
