Thermally stable high-loading single Cu sites on ZSM-5 for selective catalytic oxidation of NH3

Rigorous comparisons between single site- and nanoparticle (NP)-dispersed catalysts featuring the same composition, in terms of activity, selectivity, and reaction mechanism, are limited. This limitation is partly due to the tendency of single metal atoms ...

Phases and Interfaces in the Cr-Fe-Si Ternary System: X-ray Diffraction and Electron Microscopy Study

Philippe Buffat

The ternary Cr-Fe-Si system was investigated with X-ray diffraction, energy dispersive X-ray spectrometry, scanning and transmission electron microscopy, and electron diffraction. Samples melted at 1723 K were examined right after cooling or after annealin ...

A large planetary body inferred from diamond inclusions in a ureilite meteorite

Cécile Hébert, Emad Oveisi, Marco Cantoni, Philippe Gillet, James Badro, Farhang Nabiei, Teresa Katharina Dennenwaldt

Planetary formation models show that terrestrial planets are formed by the accretion of tens of Moon-to Mars-sized planetary embryos through energetic giant impacts. However, relics of these large proto-planets are yet to be found. Ureilites are one of the ...

Optical and morphological characterisation of low refractive index materials for coatings on solar collector glazing

Jean-Louis Scartezzini, Andreas Schueler, Marie Schaer, Stefan Mertin, Martin Joly, Estelle De Chambrier, Virginie Hody-Le Caër

Nanostructured coatings based on the elements Si, O, Mg, and F have been deposited as thin films by solegel dip-coating in a particle-free atmosphere. The refractive index of the prepared SiO2 and quaternary MgeFeSieO thin films has been determined from sp ...

Quantitative super-resolution imaging reveals protein stoichiometry and nanoscale morphology of assembling HIV-Gag virions

Suliana Manley, Thomas Pengo, Julia Gunzenhäuser

The HIV structural protein Gag assembles to form spherical particles of radius ∼70 nm. During the assembly process, the number of Gag proteins increases over several orders of magnitude from a few at nucleation to thousands at completion. The challenge in ...

Fabrication of 10 nm diameter hydrocarbon nanopores

Aleksandra Radenovic

The addition of carbon to samples, during transmission electron microscope imaging, presents a barrier to accurate analysis; the controlled deposition of hydrocarbons by a focused electron beam can be a useful technique for local nanometer-scale sculpting ...

Model-Based 2.5-D Deconvolution for Extended Depth of Field in Brightfield Microscopy

Michaël Unser, Dimitri Nestor Alice Van De Ville, François Aguet

Due to the limited depth of field of brightfield microscopes, it is usually impossible to image thick specimens entirely in focus. By optically sectioning the specimen, the in-focus information at the specimen's surface can be acquired over a range of imag ...
