X-ray diffraction results showed the amorphous structure of the aerogels remained after the acid impregnation and calcinations steps.
Besides, 90% loss in surface area and pore volume was observed in phosphated sample, strongly suggesting the destruction of aerogel structure.
The proposed structure of the samples showing possible Lewis and Brønsted acid sites is shown in Fig. 5.
Destruction of aerogel structure was observed in H3PO4 treated sample.

The synchrotron high energy XRD confirms the MC type carbide with some evolution in its orientation together with tempered martensite approaching the BCC structure at higher temperatures.
This visualizes the evolution in martensite lattice after 2-hour tempering apart from the well-known criterion that tempering martensite at higher temperature than 350 °C yields BCC structure [18].

The latter used to simulate the structure of silica aerogels.
Theoretical and computational studies have addressed the topic using percolation elastic networks, scaling concepts, simulation models of elastic phenomena, morphologically representative pattern - based approach (MRP), punctual defect chemistry, wave propagation equations, among others [2-10].
This aggregation model simulates well the structure of systems obtained via sol-gel, such as the aerogels.
The method is applicable to porous media with different structures, being capable of distinguishing and correctly giving the tendency of the values of the elasticity modulus.

The chemical composition, crystal structure, magnetic and magnetotransport properties have been investigated with regard to the degree of ordering of the Pr 3+ and Ba 2+ cations.
Introduction In recent years, manganites of the LnBaMn2O6 system (Ln = rare-earth ions) have been found to possess unique physical properties, which are related to the ordering of cations in the A-sublattice of the perovskite structure [1-15].
The investigation was devoted to the PrBaMn2O6 system, which was characterized with respect to the chemical composition, crystal structure, magnetic and magnetotransport properties and the stability of the ordered state on heating.
The nanograins combine to form a particular mosaic structure, which is common for the entire polycrystalline sample.
The grain size determines, to a certain extent, the properties of the crystal structure.

Generally, separate fluid and structure solvers are necessary for numerical fluid–structure interaction.
For large deformations, a nonlinear structure solver based on the FEM (Bhatti, 2006) was applied.
The association functions of fluid–structure interface were computed before the first time step.

And pore structure and the microstructure of the catalysts were characterized by BET surface area, nitrogen adsorption-desorption.
In generally, different templates make different catalysts, but sometimes the same kind of porous molecular sieve can be synthesized by different template agent, and the same kind of templates can be used to synthesize molecular sieves with different structures when the ratio of raw materials and process conditions is changed.
It indicates that the template has main functions in the process of synthesizing the pore structure material, which is the role of structure orientation, space filling and balance skeleton charge and so on.
As seen in the Fig. 3(a), the N2 adsorption–desorption isotherm shows that the catalyst has the typical “IV” adsorption isotherm, which indicates that the catalysts have the mesoporous pores structure.
