Atomically precise interfaces from non-stoichiometric deposition.
Complex oxide heterostructures display some of the most chemically abrupt, atomically precise interfaces, which is advantageous when constructing new interface phases with emergent properties by juxtaposing incompatible ground states. One might assume that atomically precise interfaces result from stoichiometric growth. Here we show that the most precise control is, however, obtained by using d...
متن کاملStructural, Magnetic and Catalytic Properties of Non-Stoichiometric Lanthanum Ferrite Nano-Perovskites in Carbon Monoxide Oxidation
Perovskite-type oxides of LaFe(1+x)O(3+δ) (x = 0.0, 0.2, 0.5 and 0.7) were synthesized by citrate sol–gel methodto ensure the formation of nanosized perovskites. The physicochemical properties of these LaFe(1+x)O(3+δ)materials were characterized by thermal gravimetric/differential analyses, Fourier transform infraredspectroscopy, X-ray powder diffraction, scanning electron and...
متن کاملA mathematical model for the dissolution of stoichiometric particles in multi-component alloys
A general model for the dissolution of stoichiometric particles in multi-component alloys is proposed and analysed. We introduce the concept of mass-conserving solutions and give a self-similar solution for the resulting Stefan-problem. Furthermore, we show that particle dissolution in multi-component alloys can under certain circumstances be approximated by a model for particle dissolution in ...
متن کاملZeolite – sepiolite nanoheterostructures
Zeolite–sepiolite inorganic nanoheterostructures have been hydrothermally synthesized by adding a dispersion of colloidal sepiolite to a solution able to produce a nanocrystalline zeolite (silicalite). The obtained product could be recovered in good yield by simple filtration only when the relative sepiolite concentration exceeded a threshold of 1.8 wt% in the synthesis mixture (amounting to 1:...
متن کاملSolid-state Nuclear Magnetic Resonance Study of Sepiolite and Partially Dehydrated Sepiolite
The assignment of the Si CP/MAS-NMR spectrum of naturally-occurring sepiolite clay was re-examined using Si COSY and H-Si HETCOR pulse sequences. Each of the three main resonances at 92.1, 94.6 and 98.4 ppm has been attributed to one of the three pairs of equivalent Si nuclei in the basal plane, and the resonance at 85 ppm to Q(Si-OH) Si nuclei. On the basis of the COSY experiment, the resonanc...
