Mechanical interlocking is caused by spiky geopolymer crystal type structures as can be seen in Fig.2 which mineralized on the wood veneer surface.
Growth of this crystal type structure resulted from the geopolymerisation process which involves a substantially fast chemical reaction under alkaline condition on Si-Al minerals.
This spiky crystal type structure is built by a three-dimensional polymeric chain and ring structure consisting of Si-O-Al-O bonds.
Every substance and every process that interferes with crystal type structure formation affects the cohesive bond of geopolymer.

Laser Induced graphene (LIG) with the 3D mesoporous structured flexible substrate is also used for overall water-splitting electrode material fabricated by a one-step diode laser shining on polyimide (PI) sheets [31].
This study investigates the effects of laser parameters on polyimide film, observing changes in amorphous structure carbonization, catalytic behavior, and the domains of active sites.
The Raman characterization peaks demonstrate the graphene-structured properties of LIG-3 in Fig. 5.
The G band at 1580 cm-1 corresponds to planar vibrations of sp2 carbon atoms, indicating a well-ordered graphene structure.

The shape of this hydration shell depends on the molecular structure of the additives and is stabilized by the hydrogen bonds formed among water molecules in a configuration different from that in pure water.
The low polarity molecules are also called “structure-makers” due to their ability to increase relaxation time of “cluster” of water molecules.
Since solute-solvent interactions are poor, additive does not destroy water structure, but enhance its stability.
Alcohols and ketones are examples of “structure-makers”, here, we think that AA is a kind of “structure-maker” additive, too.
But in water-rich mixtures, AA is not able to enhance polymer solubility because of the formation of hydration structures that isolate the two species.

It’s color is shallow white with stable structure, non-poisonous, non- corrosion, and it’s phase changing temperature is 8～25.
Porous material refers to a material with a certain size and number of pore structures.
Meanwhile, the silica powder has a part of obvious porous structure, and a good chemical stability
Through SEM, we can see a lot of microporous structures on the smooth spherical surface, due to the hollow thin-walled structure, a few particles’ structures are destructed, leading to the leakage when adsorbing the PCM.
Although the developed void structures are good for adsorbing PCM, activated carbon is an open hole material, unimpeded hole makes the leakage of PCM be a difficult problem.

Ordered mesoporous silicas offer excellent features such as large pore volume and high surface area, narrow pore size distribution, open pore structure and reliable desorption performance [15-18].
According to IUPAC classification, SG-1 is typical of adsorbents with a predominantly microporous structure, since the majority of pore-filling will occur at relative pressures below 0.1.

A possible way to achieve a well defined nanoparticulate structure is the Langmuir-Blodgett (LB) technique, which is commonly used to prepare molecular films on solid supports [3-5].
We derived the formula for the theoretical transmittance for a model structure consisting of a thick transparent substrate with two identical non-absorbing transparent homogeneous thin layers on both sides, analogous to the macroscopic stratified structure of an LB film.
The calculated volume fraction values for the LB films are close to this value, indicating a close packed structure of the particles.
One possible explanation for this we may find in the structure of the LB film.
The refractive indices obtained indicate a nearly close packed structure of the silica particles.

From the point of view of their technological properties, plastering, masonry, facing, adhesive compositions, the flooring mixes in civil and industrial construction most often represent combinations of basic structures (thixotropic, dilatant and pseudoplastic) and have different rheological parameters [6, 7].
In this regard, the rheograms of nonlinear visco-plastic bodies, in particular, cement suspensions, are usually divided into 4 parts and considered using different rheological models in colloid chemistry [6, 7]: - the initial part up to Р structure by the Shvedov-Bingham formula: Р = Р0i + ηpv·γ, (5) where P is the shear stress, Pa; P0 – is the yield strength, Pa; ηpv – is plastic viscosity, Pa · s; γ ̇ - is a shear rate gradient, s-1; m, n – are the constants (nonlinearity indicators); - the rheogram nonlinear portion, on which the flocculent structure of the cement paste is destroyed and the viscosity drops, can be described by the Ostwald model, and the second straight section, located in the region of maximum stresses and the shear rate gradients, characterizing
the flow with the structure almost completely destroyed, is usually described by the Bingham model.
Taking γ ̇ / P = T, we rewrite equations (7 and 8): Т = Т0 + k1·γ, (8) Т = Т0 + k2·Р, (9) where T is the turnover, expressed in (PA · s) -1; T0 is the fluidity of the practically intact structure, (Pa s) -1; k1 and k2 – define the dilution factor, Pa-1.
In contrast to the suspensions of model systems [5], the industrial dry mixture Yunis Granit glue in its multicomponent composition in addition to stabilizers (water-soluble polymers), contains strong structure-forming agents and thickeners, which change the rheograms characteristics.

An assembled structure was mounted on the base rotating stage.
It is therefore evident that the hierarchical structure of the enamel has a relevant role in distributing stresses.
Small fluctuations of the stress profiles can also be due to the underlying structure at the micron-scale.
Throughout this investigation, interesting aspects became evident, such as the influence of the underlying structure at the micro-scale.
