Solution solute in a solution is the mass of that solute expressed as a percentage of the mass of the whole solution. "Homogeneous" means that the components of the mixture form a single phase. "Heterogeneous" means that the components of the mixture are of different phase. The properties of the mixture (such as concentration, temperature, and density) can be uniformly distributed through the volume but only in absence of diffusion phenomena or after their completion. Usually, the substance present in the greatest amount is considered the solvent. Solvents can be gases, liquids or solids. One or more components present in the
Journal of Materials Chemistry A Journal of Materials Chemistry A The Journal of Materials Chemistry A is a weekly peer-reviewed scientific journal that covers the synthesis, properties, and applications of novel materials related to energy and sustainability. It is one of three journals created after the "Journal of Materials Chemistry" was split at the end of 2012. Its first issue was published in January 2013. The journal is published by the Royal Society of Chemistry and has two sister journals, "Journal of Materials Chemistry B" and "Journal of Materials Chemistry C", which cover different materials science topics. The editor-in-chief for the "Journal of Materials Chemistry"
