While some of the smallest, most useful machines known to science are the biological molecules that keep living organisms alive, there is a growing advancement of the creation of artificial molecules that have the same function and are more efficient. Molecular machines were invented in 1983 when scientists in France created a machine formed of two interlinked molecular rings. In 2016, the Nobel prize in chemistry was awarded to Feringa, Stoddart, and Sauvage who finally documented molecular machines and put them into energy‐filled states in which their movements could be controlled. From this, molecular machines became known as a group …

In the pursuit of green chemistry, adequate substitutes for lead acetate and hydrogen sulfide were investigated for use in the ACS test procedure for stabilizer in meta-phosphoric acid. In the current ACS procedure lead acetate is used to form insoluble lead phosphate. In order to remove lead from the solution lanthanum chloride was investigated with positive results. Hydrogen Sulfide is currently used to precipitate lead by forming insoluble lead sulfide. Several substitutes including oxalic acid and sulfuric acid were investigated. Preliminary testing showed that lanthanum chloride and oxalic acid are sufficient in precipitating phosphate and lead out of the sample …
