Structure of methylaluminoxane (MAO): Extractable [Al(CH3)2]
Instead of forming an outer layer composed of 12 edge-sharing six-membered rings, which would lead to a closed structure, only 11 rings are formed, leaving one site open at O15 (). The perimeter of the sheet molecule is decorated with nine four-membered rings showing several distinctly different architectures ( Fig. 2G, sites Ia and Ib ).

The lead-acid battery is a type of rechargeable battery first invented in 1859 by French physicist Gaston Planté. It is the first type of rechargeable battery ever created. Compared to modern rechargeable batteries, lead-acid batteries have relatively low energy density. Despite this, they are able to supply high surge currents. These features, along with their low cost, make them attractive for us…
