In light of the recent discovery of a partially or fully molten core of Mercury, we model plausible interior density structures of Mercury using layered cores and the elastic properties of molten core materials. We present constraints on Mercury's decompressed density, composition, and interior ...

Models for the internal structure of Mars that are consistent with its mass, radius, and moment of inertia have been constructed. Mars cannot be homogeneous but must have a core, the size of which depends on its density and, therefore, on its composition. A meteorite model for Mars implies...
As Venus’s atmosphere has probably experienced less volatile recycling over its history than Earth’s, it may be possible to constrain the volatile delivery to the primitive Venusian atmosphere from the planet’s present-day atmospheric composition. Here we investigate the long-term evolution of ...
A coordinated supply of the whole plant with sulfur (S) and nitrogen (N) requires mechanisms to regulate not only uptake and assimilation but also long-distance transport of both nutrients in the phloem and xylem as well as the plant internal cycling of S and N compounds. In trees, plant ...
Owing to the hybrid composition, mid-range zeta potentials and tunable structures, MOF crystallites can assembly at liquid-liquid interface33,34. Here we demonstrate for the first time the utilization of MOF for HIPE formation. It was found that the HIPE could be prepared by stirring the ...
In the United States, dietary data were entered directly into a computerized database (Nutrition Data System, version 2.91; University of Minnesota, Minneapolis). This system contains information on the nutrient composition of 17 000 foods, beverages, ingredients, and supplements. In the other ...
1. An internal combustion engine lubricating oil composition comprising a major amount of an oil of lubricating viscosity, at least one oil-soluble, phosphorous-containing, anti-wear compound wherein the weight percent of total phosphorous in the composition is no more than about 0.05 weight percent...
All magnetized planets in our solar system (Mercury, Earth, Jupiter, Saturn, Uranus, and Neptune) interact strongly with the solar wind and possess well de... A Keiling 被引量: 30发表: 2015年 Planetary Dynamos from a Solar Perspective Direct numerical simulations of the geodynamo and other ...
Since the original composition and microstructure of the powder can largely be retained in HVAF cermet coatings, they are not only denser and more homogeneous than HVOF ones, but also feature less oxidation and improved toughness. Therefore, HVAF-sprayed cermet coatings generally achieve a better ...
