Colloid Colloid In chemistry, a colloid is a mixture in which one substance of microscopically dispersed insoluble particles is suspended throughout another substance. Sometimes the dispersed substance alone is called the colloid; the term colloidal suspension refers unambiguously to the overall mixture (although a narrower sense of the word "suspension" is distinguished from colloids by larger particle size). Unlike a solution, whose solute and solvent constitute only one phase, a colloid has a dispersed phase (the suspended particles) and a continuous phase (the medium of suspension). To qualify as a colloid, the mixture must be one that does not settle or
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"
