The simultaneous enrichment of the Moon in both SiO2 and FeO relative to the pyrolitic mantle of the Earth is incompatible with the formation of the Moon as a result of a giant impact from terrestrial matter or an impact body (bodies) of chondritic composition and is in conflict with ...
For example, δ13C naturally varies between the low trophic level organisms in the nearshore and offshore habitats of lakes (France, 1995), and the δ13C composition of freshwater fish is used to estimate the relative amount of carbon derived from these habitats (e.g. Vander Zanden and Va...
1.2.1.4Composition, Assembly, and Hybridization of Inorganic Functional Materials The following areas have received considerable attention in recent years: (1) multiphase composition of materials including enhanced or reinforced fiber-based (or whisker-based) materials, the second-phase particle dispersion ...
Direct evidence of intense chemical weathering induced by volcanism is rare in sedimentary successions. Here, we undertake a multiproxy analysis (including organic carbon isotopes, mercury (Hg) concentrations and isotopes, chemical index of alteration (C

So far, we have demonstrated that small differences in the anhydrous composition of basalts control the nanocrystallization of Fe-Ti-oxides. Transferring our findings to a broad range of eruptive scenarios requires the investigation of hydrous magma at eruptive temperatures and pressures. This led us ...
chemistry, branch of science concerned with the properties, composition, and structure of substances and the changes they undergo when they combine or react under specified conditions. Branches of Chemistry Chemistry can be divided into branches according to either the substances studied or the types ...

The risk can increase as waste composition changes [6]. There are several properties that can render chemicals hazardous, such as being explosive, oxidizing, highly flammable, flammable, irritant, harmful, toxic, carcinogenic, corrosive, infectious, toxic for reproduction, mutagenic, sensitizer, eco...
