He also touched on how the publisher might monetise online content in future while attracting new users - selling apps bundled with subscriptions, and creating "content verticals", the aggregation of material from all of Johnston titles.
The resulting architectural morphologies allow for a convergence of aesthetic and functional concerns, enabling structural optimisation through the locally differentiated aggregation of material.
It is suggested that the reduced specific capacity is determined primarily by the aggregation of material's particles, whereas the good high-rate capability is governed not only by the size of crystallites but also by the perfectness of crystals, and imperfections in big, well-shaped crystals (like dislocations, grain boundaries, etc).
YS structures possess unique interior void space, large surface area and short diffusion distance, which can solve the problems of volume expansion and aggregation of anode materials, thus enhancing the performance of LIBs and SIBs.
Meanwhile, the addition of conductive PPy layer could facilitate the electron transport, prevent the aggregation of active materials and warrant the stability of as-formed solid electrolyte interface (SEI) films.
The enhanced cycling stability is attributed to the fact that the VO2(B MWCNT composite can prevent the aggregation of active materials, accommodate the large volume variation, and maintain good electronic contact.
The enhancement in specific capacitance and cycling stability is believed to be due to the 3D MoS2–graphene interconnected conductive network which promotes not only efficient charge transport and facilitates the electrolyte diffusion, but also prevents effectively the volume expansion/contraction and aggregation of electroactive materials during charge discharge process.
Characterization of the resulting thermoformable ionomer by dilute solution viscosity and solid-state rheology shows the effects of ion-pair aggregation on material properties over a range of ionomer composition.
A gradual aggregation of organic material on the surface, including bacterial, algae and dead material, takes place as long as the surface is not mixed.
