While nanoparticle technology is largely independent from 2-dimensional film technology or 3-dimensional bulk structures, its earlier development has helped establish the technical instrumentation and techniques for characterizing nanometals of all types.
This is in part because this area is dominated not by solid state science, but by the broad area of nanoscale chemistry of metals and metal complexes in solution.

The decrease in degradation temperature is likely due to the KH550 plasticizing effect which possibly got embedded between the highly cross-linked aromatic bismaleimide chain structures .
Little talk about the decrease in trend in mechanical properties in our system, It can be seen from table.3,4. that the mechanical properties of the composites are closely related to the coupling agents being employed, including their chemistries and concentrations.
On the other hand, if the concentration is higher than the optimum value, more than one layer of molecules of the coupling agent covers the surfaces of the filler, hence reducing the interactions of the coupling agent with both the filler and original matrix, is one of reason that why this decrease in mechanical properties happened both is matrix modification and further in filler modification. on other hand an interlayer coupling agent which displays physical or chemical reactivity with filler cannot effectively react with the matrix; It can be seen from Table 3,4 that the mechanical properties of newly modified composites are greatly dependent on the chemistry of the coupling agent used.

Adsorption Mechanism of Humic Acid on Attapulgite Based on Stumm-Schindle Surface Complexation Model

When pH≥5,I<0.1, qe changed little, When pH> 5, I> 0.1, qe slowly increased, which may be explained by several mechanisms: (1) HA moleculars decreased with ionic strength increasing, which will lead to minimalization of electrostatic repulsion between ionized oxygen groups, thus facilitated the adsorption. (2) At high ionic strength, HA diffused faster and would result in its coiled structure. (3) As ionic strength increasing, the thickness of diffused double layer on solid-liquid interface was compressed, such compression would help the clay particles and HA molecules to approach each other more closely. (4) Ionization of NaNO3 in aqueous solution caused that attapulgite existed adsorption competition for HA and water molecules achieved low level. (5) In addition, the solubility of HA was lower at higher ionic strength, which favored the mass transfer of HA from the solution phase to the solid phase of attapulgite.

It is an intrinsic property brought by ettringite formation, since ettringite has a high internal drying capacity i.e. 85%, compared with 30% for C-S-H, due to its water-rich structure (Ideker et al., 2019).
