Functional Engineering of Perovskite Nanosheets: Impact of Lead Substitution on Exfoliation in the Solid Solution RbCa2-xPbxNb3O10

Filip Mateusz Podjaski, Teresa Katharina Dennenwaldt

Tuning the chemical composition and structure for targeted functionality in two-dimensional (2D) nanosheets has become a major objective in the rapidly growing area of 2D materials. In the context of photocatalysis, both miniaturization and extending the l ...

Spin and valence dependence of iron partitioning in Earth's deep mantle

Philippe Gillet, Cécile Hébert, Marco Cantoni, James Badro, Farhang Nabiei, Hélène Marie Piet, Teresa Katharina Dennenwaldt

We performed laser-heated diamond anvil cell experiments combined with state-of-the-art electron microanalysis (focused ion beam and aberration-corrected transmission electron microscopy) to study the distribution and valence of iron in Earth's lower mantl ...

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 ...

Insight in the 3D morphology of silica-based nanotubes using electron microscopy

Teresa Katharina Dennenwaldt

Amorphous silica-based nanotubes (SBNTs) were synthesized from phosphoryl triamide, OP(NH2)(3), thiophosphoryl triamide, SP(NH2)(3), and silicon tetrachloride, SiCl4, at different temperatures and with varying amount of the starting material SiCl4 using a ...
