Increased nickel exsolution from LaFe0.8Ni0.2O3 perovskite-derived CO2 methanation catalysts through strontium doping
Perovskite-derived Ni catalysts offer the remarkable benefit of redox stability that allows their regeneration after deactivation through poisoning or Ni particle growth. Here, the catalytic activity of LaFe0.8Ni0.2O3 towards CO2 methanation was improved b ...
ELSEVIER2020Insights into the Photocatalytic Bacterial Inactivation by Flower-Like Bi2WO6 under Solar or Visible Light, Through in Situ Monitoring and Determination of Reactive Oxygen Species (ROS)
César Pulgarin, Juan Kiwi, Sami Rtimi, Stefanos Giannakis, Minoo Karbasi
This study addresses the visible light-induced bacterial inactivation kinetics over a Bi2WO6 synthesized catalyst. The systematic investigation was undertaken with Bi2WO6 prepared by the complexation of Bi with acetic acid (carboxylate) leading to a flower ...
2020Diffractive optical elements in single crystal diamond
We demonstrate the design, fabrication, and experimental characterization of near-field binary phase transmission diffractive optical elements (DOEs) in single crystal diamond. Top-hat and arbitrary pattern DOE beam shapers were numerically optimized using ...
OPTICAL SOC AMER2020Released Diclofenac Sodium Salt From Chitosan Embedding In A Hydrogel Matrix. A Theoretical And Experimental Study
Two formulations embedding diclofenac sodium salt into a chitosan hydrogel matrix with different crosslinking degree were prepared by in situ hydrogelation. The formulations were investigated by polarized light microscopy and scanning electron microscopy, ...
UNIV POLITEHNICA BUCHAREST, SCI BULL2020Three-dimensional imaging of integrated circuits with macro- to nanoscale zoom
Gabriel Aeppli, Manuel Guizar Sicairos, Christian David, Michal Odstrcil
The imaging of integrated circuits across different length scales is required for failure analysis, design validation and quality control. At present, such inspection is accomplished using a hierarchy of different probes, from optical microscopy on the mil ...
NATURE PUBLISHING GROUP2019High-quality single crystal diamond diffraction gratings fabricated by crystallographic etching
Olivier Martin, Niels Quack, Christian Santschi, Toralf Scharf, Teodoro Graziosi
We demonstrate a novel method for fabricating single crystal diamond diffraction gratings based on crystallographic etching that yields high-quality diffraction gratings from commercially available diamond plates. Both V-groove and rectangular gratin ...
2019One-dimensional facile growth of MAPbI(3) perovskite micro-rods
Mohammad Khaja Nazeeruddin, Zubair Ahmad
One-dimensional microrods (4-5 mm) of PbI2 and CH3NH3PbI3 (MAPbI(3)) with unique structural and morphological properties have been grown at room temperature. X-ray diffraction (XRD) patterns of both types of micro-rods exhibit a hexagonal system (P3m1(164) ...
ROYAL SOC CHEMISTRY2019A Study on the Characteristics of Cu-Mn-Dy Alloy Resistive Thin Films
Cu-Mn-Dy resistive thin films were prepared on glass and Al2O3 substrates, which was achieved by co-sputtering the Cu-Mn alloy and dysprosium targets. The effects of the addition of dysprosium on the electrical properties and microstructures of annealed Cu ...
2019In-situ and post annealing effect on the microstructure and the optical properties of black Cu-Co-Mn oxide spinel coating for Parabolic Trough Collector (PTC) applications
Anna Krammer, Samaneh Daviran, Josef Andreas Schuler
The present paper deals with the deposition of Cu-Co-Mn oxides thin film by magnetron sputtering to produce a black selective coating for solar Parabolic Trough Collector (PTC) systems. The effect of temperature was studied between the nominal temperature ...
IOP Science2019Enhanced second harmonic generation of gold nanostars: optimizing multipolar radiation to improve nonlinear properties
We report a detailed investigation on the second harmonic generation (SHG) emission from single 150 nm diameter non-centrosymmetric gold nanoparticles. Polarization-resolved analysis together with scanning electron microscopy images shows that these nanost ...
