Room Temperature Lattice Thermal Conductivity of GeSn Alloys.

CMOS-compatible materials for efficient energy harvesters at temperatures characteristic for on-chip operation and body temperature are the key ingredients for sustainable green computing and ultralow power Internet of Things applications. In this context, the lattice thermal conductivity (κ) of new group IV semiconductors, namely GeSn alloys, are investigated. Layers featuring Sn contents up to 14 at.

γ-BaFeO: a fresh playground for room temperature multiferroicity.

Multiferroics, showing the coexistence of two or more ferroic orderings at room temperature, could harness a revolution in multifunctional devices. However, most of the multiferroic compounds known to date are not magnetically and electrically ordered at ambient conditions, so the discovery of new materials is pivotal to allow the development of the field. In this work, we show that BaFeO is a previously unrecognized room temperature multiferroic.

Spinterface Effects in Hybrid LaSrMnO/SrTiO/C/Co Magnetic Tunnel Junctions.

Orbital hybridization at the Co/C interface been has proved to strongly enhance the magnetic anisotropy of the cobalt layer, promoting such hybrid systems as appealing components for sensing and memory devices. Correspondingly, the same hybridization induces substantial variations in the ability of the Co/C interface to support spin-polarized currents and can bring out a spin-filtering effect. The knowledge of the effects at both sides allows for a better and more complete understanding of interfacial physics.

Mifepristone followed by misoprostol compared with placebo followed by misoprostol as medical treatment for early pregnancy loss (the Triple M trial): A double-blind placebo-controlled randomised trial.

Background: Worldwide, millions of women seek treatment for early pregnancy loss (EPL) annually. Medical management with misoprostol is widely used, but only effective 60% of the time. Pre-treatment with mifepristone prior to misoprostol might improve the success rate of medical management.
