Qualitative analysis is used to identify and separatecationsandanionsin a sample substance. Unlikequantitative analysis, which seeks to determine the quantity or amount of sample, qualitative analysis is a descriptive form of analysis. In an educational setting, the concentrations of the ions to be i...
Weller et al [Refs. 2 and 3] developed a method for reporting the presence of metal cations and protons using the Photo-induced Electron Transfer (PET) and/or Photo-Induced Energy Transfer (PEET or EET) signaling approaches. US application No. 2005/147534 [Ref. 4] relates to a class of...
ZnO, a-TiO2). Rather than leading to hole localisation in the interstitial atom and/or neighbouring anions (metastable state), the defect can accommodate the charge deficiency by forming oxygen dimers, resulting in highly favourable
For the ML investigation, we first generated a dataset of the electronic structures of halide double perovskites. Figure1apresents the crystal structure of the double perovskiteA2B1+B3+X6. Compared to the original perovskite, this structure incorporates two different types of cations,B1+andB3+, ins...
The source attribution of observed variability of total PM2.5 concentrations over Halifax, Nova Scotia, was investigated between 11 July and 26 August 2011 using measurements of PM2.5 mass and PM2.5 chemical composition (black carbon, organic matter, anions, cations and 33 elements). This was ...
(Supplementary SubsectionII.E). For ceria and rutile, the two electrons donated by the defect localise on lattice cations reducing them to Ce/Ti(III). This leads to many competing states depending on both the defect-polaron and polaron-polaron distances. While the different localisation ...
