What is/are Multi Element Composition?Multi Element Composition - In particular, the obtained data make a prominent input to the study of the multi-element composition of marine diatom species, namely Chaetoceros spp.  In this study, for the first time, a new type of combined cable wire (CCW) with multi-element composition has been designed and developed for arc additive manufacturing (AAM) of non-equiatomic Al-Co-Cr-Fe-Ni high-entropy alloy.  Many factors may cause the Voc loss of kesterite: (1) the narrow phase stability makes it difficult to achieve highly uniform absorber composition, which can result in bandgap fluctuation and secondary phases; (2) the similar ionic size of Cu and Zn leads to high concentration of Cu–Zn antisite defects (Cu–Zn disorder), which may cause electrostatic potential fluctuation and band tailing; (3) the multi-element composition and the variable valence of Sn lead to complicated defect property, causing serious recombination in absorber bulk and interfaces[4−8].  To study the multi-element composition of aerosols in high-latitude areas is a major issue for identifying the regional and global sources of pollution.  In this study, we present a quantification method for the multi-element composition of minerals and a statistical method to investigate chemical similarity among samples. 
Multi-element composition of more than 400 Cu-bearing tourmaline samples (majority elbaite, Na-rich) was analysed using LA-ICP-TOF-MS that cover various colors, qualities and provenances available in the gem and jewellery trade. Determination of the multi-element composition of urban soil contributes to an accurate assessment of the quality of the urban environment.
