The change of the volume caused by adsorption of a fatty acid (e.g. acetic acid, propionic acid) on activated coal is continuously controlled by means of a dilatometrical titration. According to the adsorption isothermes the formation of a mono- and then a dimolecular adsorption layer can be...

Among other things, it means that in New Zealand, these paper-based wrappers by Mars must be placed in the rubbish bin and cannot be recycled. British supermarket chain Asda introduced plant-based packaging for its own-brand tea bags. They are now made from polylactic acid, derived from corn...

Mathematical axioms are not axioms of general truth. What is true ofrelation- of form and quantity - is often grossly false in regard to morals, for example. In this latter science it is very usuallyuntrue that the aggregated parts are equal to the whole. In chemistry also the axiom fails...
