The experimental structure of the cyclodextrin-based metal-organic framework (CD-MOF) was obtained from the Cambridge Crystallographic Structure Database (CCSD No. 773709) [22].
To model the adsorption behavior of Crystal Violet (CV) within the CD-MOF structure, simulated annealing was performed using the Universal Force Field (UFF) on the previously optimized CD-MOF crystal structure.

The porous structure of scaffold materials is closely related to water molecules.
In this study, the porous structure of the hyaluronic acid/gelatin scaffold may be attributed to the ratio of the two components, resulting in a change in pore size structure and size.

We considered Si(001) and Si(111) substrates with diamond structures.
Fig. 1 Optimized structures of Cu13, Cu19 and Cu147 by Monte Carlo calculations.
Si has a diamond structure, with four bonds to the nearest neighbors in a tetrahedral form.
From a chemistry point of view, the formation of the interface Cu-Si bond weakens the lattice Cu-Cu and Si-Si bonds, resulting in the breaking of the latter bonds for the reaction to occur.
They found that the diamond structure of Si favors the (100) surface for reaction.

Introduction Silica has been used as a major precursor for a variety of inorganic and organometallic materials which have applications in synthetic chemistry as catalysts, and in thin films or coatings for electronic and optical materials, in advanced biomedical material as drug delivery.
CTAB surfactant is added to form mesoporous structure of silica nanoparticle (MSNp).
Silica extracted had amorphous phase-like structure and identified Si-O-Si functional bond [7].
After calcination at 600°C, RHA still retains its corncob-like structure.

This work follows the specific precipitation of evaporites through progressive evaporation of Chott Djerid brines using geochemical, isotopic and mineralogical approaches, to explain the intricacy of the functioning of saline frameworks basically controlled by the climate and the underlying geochemical structure acquired from the geologic system.

The chemistry of the initial brine can be explained through the dissolution of evaporites formations at the surface by runoff [55] or subsurface by water leaching [56].

As expected, the microstructure after TM rolling was finer due to austenite sub-structure development below the no-recrystallisation temperature which increases the amount of ferrite nucleation sites.
Chemistry of the Ni-containing Nb-Ti-V steel, mass-%, S and N are in ppm.
This is due to austenite sub-structure development below the TNR which increases the amount of ferrite nucleation sites [9].

In addition, several auxiliary structures are installed into trimaran planing hull so as to improve the hydrodynamic performance, such as the air-inducing slot and spray strip in the longitudinal distribution of the main hull and the knuckles on both inside and outside the outriggers [1].
By virtue of the unique structure of hull and hydrodynamic effects inside channels, high-speed trimaran planing hull still remains stable at a high speed and the dolphin motion would take place at a higher speed compared to conventional planing hull.
For trimaran planing hull, because of its unique structure of channel and outrigger and the interaction of air and water within the channel at high speeds, the mechanism is more complex.
