I've got a question for you guys. Do you think I can fit this length of polystyrene into this jar? Yes. No. No? Yeah? I like that – you lot have got some faith in me! Excellent. Right, this is what we ...

Despite the importance of predicting solubility, it is not an easy matter. One approach, using 'brute force' simulations, requires long computing times. Other techniques, while faster, fail to predict ...

Introduction Have you ever added a spoon of sugar to your tea and wondered why it disappeared? Where did it go? The sugar did not actually disappear—it changed from its solid form into a dissolved ...

Introduction What is your favorite type of candy? Have you ever wondered why you like this candy so much? Is it its taste, how it feels in your mouth—or both? Cooks and food scientists study how ...

SEVERAL valuable and interesting methods 1 have been devised for the measurement of the adsorption of soluble substances on the surface of a solution, from the moving bubble method initiated by Donnan ...

WASHINGTON, D.C., June 6, 2017 -- The solubility of any given substance -- the measure of how well the substance dissolves into another substance referred to as the solvent -- depends on basic ...
