In chemistry, concentration refers to the amount of a substance in a defined space. Another definition is that concentration is the ratio ofsolutein a solution to eithersolventor totalsolution. Concentration is usually expressed in terms ofmassper unitvolume. However, the solute concentration may al...

This reaction rate for a general chemical reaction aA + bB → cC + dD can be expressed in terms of the concentrations of the reactants by the equation: rate=k[A]x[B]yrate=k[A]x[B]y Here,kis a constant; [A] and [B] are the concentrations of thereactants; andxandyare the...
The interactions between dipoles in unit cells cause polarisation alignment resulting in a polarisation bound charge at the surface of the block of ceramic. This polarisation charge affects surface topography, chemical reactivity, optical and electronic properties of ferroelectric surfaces and interfaces, ...
3., 4. This is somewhat surprising given the foundational position of complexes such as bis-benzene chromium in our understanding of transition metal chemistry, and its role in chemistry coursework, along with that of “piano-stool” arene complexes in medicine.5 Just a handful of simple, ...
What does this mean for applications of AI in drug discovery? AI can, in principle, deliver all of the above aims: it can make decisions faster (predictions are faster than experiments) and more cheaply (predictions cost less than experiments), and lead to better decisions (where suitable dat...
