Comparing the Chemical Compositions of the Sun and Earth
نویسندگان
چکیده
We compare the solar and terrestrial bulk elemental compositions. We show that the Sun and Earth share the same refractory elemental abundances, and that, to first order, the Earth is a devolatilized piece of the Sun left over from the Sun’s formation. We discuss the advantages of an aluminium normalization for this comparison over the traditional silicon normalization.

Design, construction and calibration of single channel sun-photometer for study of aerosols
Aerosols are tiny liquid or solid particles suspended in the air have a strong influence on air quality, human health and climate change. Sun-photometer is a tool for measuring the optical and physical characteristics of aerosols by using sunlight at various wavelengths from the Earth surface. In this paper, the design, construction, and calibration of a single channel sun-photometer is present...

متن کاملChemical Regeneration of Exhausted Granular Activated Carbon Used in Citric Acid Fermentation Solution Decoloration
An improved chemical regeneration of the granular activated carbon (GAC) exhausted by the color (pigments and pollutants) from citric acid fermentation solution (CAF) was investigated. In the experiments, improved means were adopted to advance the traditional chemical regenerating method and the adsorption capacity of the first time renewed GAC is 103% of original GAC. Using oxidan...
