Modification of Molybdenum Structural Environment in Borosilicate Glasses with Increasing Content of Boron and Calcium Oxide by 95 Mo MAS NMR

Magali Magnin、Sophie Schuller、Cyrille Mercier 等 8 位作者2011-11-04Journal of the American Ceramic Society

In nuclear borosilicate glasses, when molybdenum is in too high concentration and when it combines with other elements such as alkali and alkaline‐earth elements it may form crystalline molybdates, including sodium molybdate, Na 2 MoO 4 , during melt cooling. In a nuclear vitrification context, the origin of this phen…

Zixue Su、Wuzong Zhou、Feilong Jiang 等 4 位作者2011-11-04Journal of Materials Chemistry

A localized dielectric breakdown model with good universality is introduced to explain the pore initiation, separation and growth processes of nanoporous and nanotubular anodic metal oxides. It is suggested that the degree of localized dielectric breakdown, which is mainly determined by the dielectric strength and ene…

Relevance of the Nitrite Route in the NOx Adsorption Mechanism over Pt–Ba/Al2O3 NOx Storage Reduction Catalysts Investigated by using Operando FTIR Spectroscopy

Luca Lietti、Marco Daturi、Vanessa Blasin‐Aubé 等 6 位作者2011-11-04ChemCatChem

Nitrites dominate! Nitrites and nitrates are formed on the catalyst surface upon storage of NOx over a model Pt–Ba/Al2O3 NOx storage–reduction catalyst. Nitrites are formed through the oxidation of NO at the Pt–Ba interface (nitrite route), while nitrates are formed upon nitrite oxidation and/or NO2 adsorption followi…

Laurent Simon、Cristina Bena、F. Vonau 等 5 位作者2011-11-04Journal of Physics D Applied Physics

We present here an overview of the Fourier-transform scanning tunnelling spectroscopy technique (FT-STS). This technique allows one to probe the electronic properties of a two-dimensional system by analysing the standing waves formed in the vicinity of defects. We review both the experimental and theoretical aspects o…
