Strontium ruthenate (SRO) is an oxide of strontium and ruthenium with the chemical formula Sr₂RuO₄. It was the first reported perovskite superconductor that did not contain copper. Strontium ruthenate is structurally very similar to the high-temperature cuprate superconductors, and in particular, is almost identical to the lanthanum doped superconductor (La, Sr)₂CuO₄. However, the transition temperature for the superconducting phase transition is 0.93 K, which is much lower than the corresponding value for cuprates.
A magnetoelectric heterojunction film and a preparation method thereof
The application discloses a magnetoelectric heterojunction film and a preparation method thereof. The magnetoelectric heterojunction film comprises a strontium titanate base layer, a strontium ruthenate electrode layer, a bismuth ferrite ferroelectric material layer and a SmCo-based ferromagnetic material layer which are stacked in sequence. The magnetoelectric heterojunction film has the multi-ferroelectric layer room-temperature magnetoelectric coupling effect and the excellent magnetic performance of the ferromagnetic layer, and the magnetoelectric coupling effect of the heterojunction film can be enhanced through the strong exchange bias effect at the interface.

Organism and method for promoting directional growth thereof
PCT designated stageWO2026066702A1Skeletal/connective tissue cellsElectrical/wave energy microorganism treatmentStrontium titanateBiological body
Disclosed in the present invention are an organism and a method for promoting the directional growth thereof. The organism comprises at least one of a single cell, a multicellular body, a tissue and an organoid. The method comprises the step of subjecting the organism to a strong-to-weak gradient electric field environment. In the present invention, a layered material is constructed using strontium titanate as a substrate, strontium ruthenate as a regulating layer, and bismuth ferrite as an internal electric domain polarization layer. A surface potential, i.e., a gradient electric field, is generated by the layered material so as to guide the directional growth of the organism in vitro, thereby constructing an organoid that highly mimics the morphology, structure and function of a corresponding tissue in vivo.
