Crystal structure of Sr5Te4O12(OH)2, the first basic strontium oxotellurate(IV)

Acta Crystallographica Section E: Crystallographic Communications, 2016
The asymmetric unit of the title basic strontium oxotellurate(IV), Sr5Te4O12(OH)2 {systematic name pentastrontium tetrakis[oxotellurate(IV)] dihydroxide}, comprises three SrII cations (one with site symmetry 2) and two TeIV atoms, as well as seven O ...

Cryogenic Deformation Behavior of TiAl and Insights Into Embrittlement After High‐Temperature Exposure Combined With Secondary Ion Mass Spectroscopy of Near Surface Chemistry

Advanced Engineering Materials, EarlyView.
Near‐surface deuterium enrichment profiles for different microstructural types of TiAl after exposure at 700 °C in a heavy water‐containing environment. The deuterium levels are significantly higher than expected from natural occurrence, indicating that the heavy water dissociated during the exposure treatment and entered the specimens.

Structure and microstructure characterization of the La2SrB10O19 glass-ceramics [PDF]

Science of Sintering, 2019
The crystal structure of new lanthanum strontium borate glass-ceramics was refined by the Rietveld method. The results showed that La2SrB10O19 has the monoclinic crystal structure, space group C2 (No. 5) with a = 11.1170(6), b = 6.5667(3), c = 9.

Composites of Shellac and Silver Nanowires as Flexible, Biobased, and Corrosion‐Resistant Transparent Conductive Electrodes

Advanced Functional Materials, EarlyView.
Shellac, a centuries‐old natural resin, is reimagined as a green material for flexible electronics. When combined with silver nanowires, shellac films deliver transparency, conductivity, and stability against humidity. These results position shellac as a sustainable alternative to synthetic polymers for transparent conductors in next‐generation ...

Control of Polarization and Polar Helicity in BiFeO3 by Epitaxial Strain and Interfacial Chemistry

Advanced Functional Materials, EarlyView.
In BiFeO3 thin films, the interplay of interfacial chemistry, electrostatics, and epitaxial strain is engineered to stabilize homohelicity in polarization textures at the domain scale. The synergistic use of a Bi2O2‐terminated Aurivillius buffer layer and a highly anisotropic compressive epitaxial strain offers new routes to control the polar‐texture ...

Surface complexation model for strontium sorption to amorphous silica and goethite

Geochemical Transactions, 2008
Strontium sorption to amorphous silica and goethite was measured as a function of pH and dissolved strontium and carbonate concentrations at 25°C. Strontium sorption gradually increases from 0 to 100% from pH 6 to 10 for both phases and requires multiple

Chemical State Detection and Charge Transfer in Complex Oxide Heterostructures via In Situ Auger Electron Spectroscopy

Advanced Functional Materials, EarlyView.
In situ Auger Electron Spectroscopy resolves oxidation states with high fidelity during the pulsed laser deposition of multivalent perovskite manganate and vanadate heterostructures. The chemical‐state signature is carried by the valence‐electron population of the transition‐metal cation, read out through the relative intensities of Auger fine ...

Optical pumping of 5s4d^{1}D_{2} strontium atoms for laser cooling and imaging

Physical Review Research
We present a faster repumping scheme for strontium magneto-optical traps operating on the broad 5s^{2}^{1}S_{0}−5s5p^{1}P_{1} laser cooling transition. Contrary to existing repumping schemes, we directly address lost atoms that spontaneously decayed to ...
