Synthesis and Electronic Structure of the Fractionally Occupied Double Perovskite EuTa2O6 with Ordered Europium Vacancies

open access: yesAdvanced Functional Materials, Volume 36, Issue 10, 2 February 2026.
Two‐dimensional electronic states are the foundation of modern semiconductor technology. Here, we report molecular‐beam epitaxy growth of fractional double perovskite, EuTa2O6. Reciprocal space mapping and transmission electron microscopy confirm a layered ordering of A‐site cations.

An MRI‐based macro‐ and microstructural neuroimaging‐wide association study of subsequent cognitive impairment

open access: yesAlzheimer's &Dementia, Volume 22, Issue 2, February 2026.
Abstract INTRODUCTION This study longitudinally examined 154 magnetic resonance imaging (MRI) biomarkers in cognitively normal (CN) individuals to identify structural brain changes most strongly associated with subsequent cognitive impairment (SI). METHODS We analyzed 509 Baltimore Longitudinal Study of Aging participants (age ≥ 50, CN at baseline ...

Treatment Initiation Among Black and White Older Adults With Multiple Myeloma: A SEER‐Medicare Analysis

open access: yesCancer Medicine, Volume 15, Issue 2, February 2026.
ABSTRACT Background This study aims to describe time to treatment initiation for Black and White older adults with multiple myeloma (MM), and to test the hypothesis that Black/White disparities in treatment initiation have increased over time. Methods Black and White older adults (65+) diagnosed with myeloma 2007–2017 were identified in the SEER ...
