The Aluminum-Ion Battery: A Sustainable and Seminal Concept?
TLDR
The constraints for a sustainable and seminal battery chemistry are described, and an assessment of the chemical elements in terms of negative electrodes and electrolyte materials are presented, which present a promising path for the accelerated development of novel materials and address problems of scientific communication in this field.

Picometer polar atomic displacements in strontium titanate determined by resonant X-ray diffraction
TLDR
Using resonant X-ray diffraction, the modified structure of strontium titanate corresponds to that of well-known ferroelectrics such as lead titanate and is determined with sub-picometer precision and shown that the atomic structure has remained elusive and could not be obtained by standard methods.

The anisotropy of oxygen vacancy migration in SrTiO3
TLDR
Electroformation of pure SrTiO3 follows an Arrhenius behavior, implying an ionic migration process of intrinsic oxygen defects, and mobility of oxygen vacancies is enhanced in [Formula: see text] compared to [formula:see text] and [Form formula: seeText] by up to half an order of magnitude.

Migration-induced field-stabilized polar phase in strontium titanate single crystals at room temperature
Local reversible structural changes in SrTiO3 single crystals in an external electric field are induced by oxygen redistribution. We present in situ x-ray diffraction measurements during and…
