Janus-like W-Cu films exhibiting a tilted columnar architecture are prepared by GLAD co-sputtering using W and Cu targets. Co-deposition of these two-immiscible metals leads to contrasted morphologies in the columns growth. Observations scanning electron microscopy reveal different structural features at micro- nanoscales as face or target. In front flux, dense with saw-tooth profile, whereas g...

Surface structure, composition and segregation properties of bimetallic nanoalloys are crucial in determining chemical reactivity and activity [1,2]. RhAg nanoalloy is of interest in catalysis since Rh, although expensive and scarce, is used in wide range of catalytic process. Alloying Rh with Ag seems reasonable due to Ag’s abundance in nature and low cost. Unfortunately, there are no stable p...

Combining two Bose-Einstein condensates (BECs) may result in a miscible or immiscible mixture, even violent implosion. We theoretically demonstrate that dipolar two-component BECs produce far richer physics than their nondipolar counterparts. Intriguingly, when both components have equivalent dipoles, the transition to immiscibility is largely unaffected by physics, yet dipoles maximally affect...

Earth's core is composed primarily of iron (Fe) with about 10% by weight of lighter elements. The lighter elements are progressively enriched in the liquid outer core as the core cools and the inner core crystallizes. Thermodynamic modeling of Fe-O-S liquids shows that immiscible liquids can exist at outer-core pressures (136 to 330 gigapascals) at temperatures below 5200 kelvin and lead to lay...

The mutual immiscibility of hydrogenated and fluorinated surfactants at interfaces frequently leads to phase-separation, which provides a useful and flexible method for patterning air-water and solid-air interfaces. In this article, we review recent advances in the use of hydrogenated-fluorinated surfactant mixtures to achieve interfacial patterning. For even relatively simple systems comprised...

Introduction: The genesis of chondrites is a key problem in the concept of the planetary evolution of the solar system, but explanations proposed for the origin of the silicate chondrules and Fe-rich matrix of chondrites notably differ. Most cosmochemists deny genetic links between chondrules and their host matrix, with the chondrules and matrix considered to be genetically separated and genera...
