Charge transfer or redistribution at oxide heterointerfaces is a critical phenomenon, often leading to remarkable properties such as two-dimensional electron gas and interfacial ferromagnetism. Despite studies on LaNiO/LaFeO superlattices and heterostructures, the direction and magnitude of the charge transfer remain debated, with some suggesting no charge transfer due to the high stability of Fe (3d). Here, we synthesized a series of epitaxial LaNiO/LaFeO superlattices and demonstrated partial (up to ~0.

Adenocarcinomas from multiple tissues can converge to treatment-resistant small cell neuroendocrine (SCN) cancers composed of ASCL1, POU2F3, NEUROD1, and YAP1 subtypes. We investigated how mitochondrial metabolism influences SCN cancer (SCNC) progression. Extensive bioinformatics analyses encompassing thousands of patient tumors and human cancer cell lines uncovered enhanced expression of proliferator-activatedreceptor gamma coactivator 1-alpha (PGC-1α), a potent regulator of mitochondrial oxidative phosphorylation (OXPHOS), across several SCNCs.

Article Synopsis
  • Strong coupling between polarization and strain in ferroelectric complex oxides allows for significant tuning of their properties, particularly demonstrated in KNbO thin films.
  • Applying biaxial strain can drastically increase the Curie temperature, with predictions indicating it could exceed 1325 K under certain conditions.
  • Enhanced properties such as a 46% increase in remanent polarization and a 200% boost in optical second harmonic generation coefficients make lead-free KNbO a promising candidate for high-temperature ferroelectric memory and quantum computing applications.
