What is the ionic charge of the metal cation in the following compound? {eq}\displaystyle \rm Sn(OH)_2 {/eq} Ionic Compound: Ionic compounds are composed of two or more charged particles called ions. These ions are cations and anions. Cations (positively charged particles...
Figure 1b depicts the schematic of the NNK which consists of an artificial neural network and a neuron kinetics module. The introduced neural network (with more than two hidden layers) is designed to learn the nonlinear interactions between input neurons (i.e., atoms and vacancy), and to out...
Knowledge of the oxidation state of metal centres in compounds and materials helps in the understanding of their chemical bonding and properties. Chemists have developed theories to predict oxidation states based on electron-counting rules, but these can fail to describe oxidation states in extended cr...
Machine learning (ML), as an interdisciplinary technique covering multiple fields of statistics, computer science, and mathematics, has been widely used in the medical, bioinformatics, financial, and agriculture fields [1,2,3,4,5]. Especially in the materials field, ML technology has accelerated ...
The ozone-based AOPs have been proved to be effective in detoxifying an ample range of industrial effluents containing recalcitrant organics, pharmaceutical products, pesticides, phenols, dyes, etc. Ozone based AOP processes such as O3/UV, O3/H2O2, O3/Fe (II), O3/metal oxide catalyst, O3/...
The role of transition metal complexes is overviewed for the iron, copper and chromium compounds, for which photoreactivity is of crucial environmental importance. Attention is paid to these complex systems, in which metal centres are photoreduced by organic matter under solar irradiation and re-oxid...
The invention concerns the use as additive for improving properties of resistance to arc tracking and arc erosion: of a mixture A, B or C formed by: concerning mixture A: A1: platinum; and A2: at least an inorganic compound A2.1 of a metal with several degrees of oxidation selected from...
4. Given the masses and atomic weights of two or more elements in a metal alloy, calculate the weight percent and atom percent for each element. 5. For each of edge, screw, and mixed dislocations: (a) describe and make a drawing of the dislocation, (b) note the location of the ...
Over the years, intensive research works have been devoted to conducting polymers due to their potential application in many fields such as fuel cell, sens
This is readily seen when looking at the local structure of these compounds where the metal cation is bonded to more than one anionic ligand to form a heteroleptic polyhedron (Box 1). The different anionic characteristics, such as charge, ionic radii, electronegativity, and polarizability (Table ...
