According to Leibniz, bodies (qua material) are aggregates, and an aggregate, of course, is not a substance on account of its lack of unity.
On the other hand, the highest amount of the zeolite ZSM-5 material within the FCC matrix was aggregated into larger domains (ca. 1 5 μm) with more or less similarly oriented zeolite crystallites.
Our database distinguishes 65 materials or material types which are aggregated into six main material groups: biomass, fossil energy carriers, metals, industrial minerals, construction minerals, and traded products which cannot be allocated to one of the main raw material groups.
As the material footprint calculations can be performed separately for various raw materials and then be aggregated into the four major material groups, Fig. 2 depicts the regional origin of raw materials serving the EU final demand for biomass, fossil fuels, minerals and metal ores.
In order to generate the physical satellite to the MRIO system, the around 380 categories of primary raw material extraction data are aggregated into the 33 extraction sectors of EXIOBASE (see Additional file 4: Correspondence table between raw materials and EXIOBASE sectors).
The impact assessment is performed separately for the materials, and results are aggregated at the end of the analysis.
The site is aiming to become a "music information hub": a content deal with YouTube guarantees plenty of video material and user reviews are aggregated from Amazon.co.uk.
Most of the material currently on the site is aggregated from other locations not much original value there.
Obviously, the particles are aggregated into a layered material.
