Rapid, sensitive and on-site monitoring of meat spoilage is highly essential for food safety. Hydrogen sulfide (H2S) a typical volatile, produced during enzymatic hydrolysis considered as reliable marker evaluating freshness. Herein, novel nano-bionic sensor based on the superior catalytic activity ruthenium nanoparticles (Ru NPs) has been fabricated H2S quantification. The sites Ru NPs were po...

The increasing scarcity of iridium (Ir) and its rutile-type oxide (IrO2), the current state-of-the-art oxygen evolution reaction (OER) catalysts, is driving transition toward use mixed Ir oxides with a highly active yet inexpensive metal (IrxM1–xO2). Ruthenium (Ru) has been commonly employed due to high OER activity although electrochemical stability in Ir-Ru nanoparticles (IrxRu1–xO2 NPs), esp...

We combine classical empirical potentials and density functional theory (DFT) calculations to characterize the catalyst/electrode interface of a promising device for artificial photosynthesis. This system consists of inorganic Ru-polyoxometalate (Ru-POM) molecules that are supported by a graphitic substrate functionalized with organic dendrimers. The experimental atomic-scale characterization o...

The preparation of Ru nanoparticles supported on γ-Al2O3 followed by chemical reduction using RuCl3 as a precursor is demonstrated, and their properties are compared to prepared impregnation with Ru3(CO)12 subsequent thermal decomposition. resulting from slightly larger (1.2 vs. 0.8 nm). In addition, were deposited Stöber SiO2 both deposition techniques. These particles than the ones (2.5 3.4 n...

Abstract Lately novel strategies to enhance the sensing properties on iron oxide have been proposed achieve high performance gas sensors for acetone detection. In this working report, synthesis of iron-glycerate (Fe-Gly) using glycerol combine with Fe 3+ is first presented. Depending thermal treatment, compound can evolve into ?-Fe 2 O 3 , ?/?-Fe and ?-Fe . shows better as far detection concern...
