The phrase "aggregation of material" is correct and usable in written English.
It can be used in contexts where you are discussing the collection or accumulation of various materials or data.
Example: "The aggregation of material from different sources is essential for a comprehensive analysis of the topic."
Alternatives: "collection of materials" or "compilation of resources".
It's really a sort of midi-payment rather than a micropayment because you're still buying an aggregation of material in one go.
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).
The HIM micrographs revealed an association between a fungal hypha and mineral grain (Fig. 6b) and an aggregation of materials on the fungal hypha (Fig. 6c).
Thus, the decision was made to process the collection as Lawrence A. Cremin's personal papers, rather than an artificial aggregation of materials about or related to Lawrence A. Cremin.
Results indicated three-dimensional conjugated structures can efficiently decrease the aggregation of materials, resulting in the improving of the light-emitting efficiency.
Specifically, the linear mixing model (LMM) [1] assumes that the spectral signature of one pixel of the hyperspectral image is a linear combination of the endmember spectra corresponding to the aggregation of materials in the scene due to reduced sensor spatial resolution.
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.
They can usefully be thought of as having three basic types: "section" identifiers, which (sensibly) identify sections, "subsection" identifiers, which apply to named chunks within a section, and "supersection" identifiers, which identify aggregations of materials above the section level but below the level of the Title: subtitles, parts, subparts, chapters, and subchapters.
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.
