The Planets Mercury and Venus [PDF]
Nature, 1928 THROUGH the kindness of Dr. Deslandres, I followed Mercury here last spring and summer with the 33-inch refractor, and all recent observations confirm my 1927 results with the same instrument as to the correctness of the 88-day rotation period and as to the presence of whitish atmospheric veils of low albedo, which occasionally distort and conceal the ...

Small, EarlyView.Platinum nanoparticles are immobilized on hollow carbon spherogels using supercritical deposition, enabling precise control over nanoparticle size, loading, and spatial distribution. Incorporation of an internal TiO2 sublayer in the hollow sphere support induces enhanced metal–support interactions, markedly improving hydrogen evolution activity and ...

Formation of the Terrestrial Planets from a Narrow Annulus
, 2009 We show that the assembly of the Solar System terrestrial planets can be successfully modelled with all of the mass initially confined to a narrow annulus between 0.7 and 1.0 AU.

Small, EarlyView.High‐entropy metal chalcogenides (HEMC) incorporating five equimolar transition metals and sulfur were synthesized via an efficient solvothermal method. The resulting HEMC exhibits a single‐phase pyrite (Pa‐3) crystal structure, which was thoroughly characterized using advanced structural analysis techniques. As an anode material, the HEMC demonstrates

Outline of a Washing Treatment to Improve Electric Arc Furnace Slag Environmental Behavior
steel research international, EarlyView.This study evaluates a water‐washing treatment for electric arc furnace slag to reduce the leaching of hazardous elements (Cr, Ba, Mo, and V), enabling its reuse. The process effectively decreases leachate concentrations. Using the treated slag as a substitute aggregate in concrete reduces greenhouse gases emissions by 42.5% compared to landfilling ...

Mercury's Exosphere During MESSENGER's Second Flyby: Detection of Magnesium and Distinct Distributions of Neutral Species [PDF]
, 2009 During MESSENGER's second Mercury flyby, the Mercury Atmospheric and Surface Composition Spectrometer observed emission from Mercury's neutral exosphere. These observations include the first detection of emission from magnesium.

Environmental Toxicology, EarlyView.ABSTRACT Over the past decades, the growth in human population and economic activities has led to an increase in maritime traffic. This rise puts additional pressure on marine environments, vessel fuel spills being considered to have a major impact on the ecosystem.

Mercury Exploration: Looking to the Future [PDF]
Prior to the return of data from the NASA MErcury Surface, Space ENvironment, GEochemistry, and Ranging (MESSENGER) spacecraft], information relating to Mercury was limited. From the NASA Mariner 10 flybys, in 1974 and 1975, ~45% of the planet was imaged,

Mass-Radius Relations and Core-Envelope Decompositions of Super-Earths and Sub-Neptunes
, 2014 Many exoplanets have been discovered with radii of 1-4 Earth radii, between that of Earth and Neptune. A number of these are known to have densities consistent with solid compositions, while others are "sub-Neptunes" likely to have significant hydrogen ...
