TL;DR: In this paper, the existence of a coreless terrestrial planet is discussed, whereby the oxidation state during planetary accretion and solidification will determine the size or existence of any metallic core.
Abstract: Differentiation in terrestrial planets is expected to include the formation of a metallic iron core. We predict the existence of terrestrial planets that have differentiated but have no metallic core--planets that are effectively a giant silicate mantle. We discuss two paths to forming a coreless terrestrial planet, whereby the oxidation state during planetary accretion and solidification will determine the size or existence of any metallic core. Under this hypothesis, any metallic iron in the bulk accreting material is oxidized by water, binding the iron in the form of iron oxide into the silicate minerals of the planetary mantle. The existence of such silicate planets has consequences for interpreting the compositions and interior density structures of exoplanets based on their mass and radius measurements.

TL;DR: In this article, a simple method for the determination of chloride takes a total time of 15 min. Samples are mixed with silica in the ratio 1∶1, and the chloride is liberated in an induction furnace by pyrohydrolysis within ca. 10 min.
Abstract: This simple method for the determination of chloride takes a total time of 15 min. Samples are mixed with silica in the ratio 1∶1, and the chloride is liberated in an induction furnace by pyrohydrolysis within ca. 10 min. The chloride is collected in a 0.020 M sodium-hydroxide solution. This solution is filled up to 200 ml with twice distilled water and absorption is measured with ferric ammonium sulphate and mercury(II) thiocyanate solution by a Zeiss Elko II photometer. Analysis of three international reference samples show excellent accuracy with a standard deviation of less than 4% (e.g. for a chloride content of 117 ppm in Andesite AGV-1).

TL;DR: The component of Titan yellow most reactive towards magnesium has been isolated from the acetone-extracted dye by adsorption chromatography on Sephadex G-10 as discussed by the authors.
Abstract: The component of Titan yellow most reactive towards magnesium has been isolated from the acetone-extracted dye by adsorption chromatography on Sephadex G–10. It is so reactive that it can be used at a concentration as small as 0·008 per cent., at which concentration the response is linear between 20 and 150 µg of magnesium.Values found for the magnesium content of silicate minerals agree with those obtained by spectrographic and gravimetric methods.
