We report fabrication of a hybrid organic semiconductor-inorganic complex oxide interface of rubrene and La0.67Sr0.33MnO3 (LSMO) for spintronic devices using pulsed laser deposition (PLD) and investigate the interface structure and chemical bonding-dependent magnetic properties. Our results demonstrate that with...

Synthetic hackmanites, Na8Al6Si6O24(Cl,S)2, showing efficient purple tenebrescence and blue/white persistent luminescence were studied using different spectroscopic techniques to obtain a quantified view on the storage and release of optical energy in these materials. The persistent luminescence emitter was identified...

Temporal coarse graining of CO2 and N2 diffusion in zeolite NaKA: from the quantum scale to the macroscopic.

BACKGROUND: The purpose of this study was to describe the knowledge of Russian nursing students regarding HIV and Acquired Immuno-Deficiency Syndrome (AIDS), and their attitudes towards caring for people/patients living with HIV or AIDS (PLWHA - People Living With...

Single exosome study reveals subpopulations distributed among cell lines with variability related to membrane content.

Journal of extracellular vesicles
