However, little is known about the nucleotides/protein structure and in vivo activity of CAs in molluscs.
According to the trace element chemistry of the M. galloprovincialis shells, the most polluted sample locations were in the middle Adriatic also, where chemical and heavy industries are located and where sewage is discharged into the coastal sea.
Besides emphasizing CA as a putative biomarker of pollution, our study allowed characterizing the primary structure of CA from the edible mussel.

The 2θ at peak 25.4° confirms the TiO2 anatase structure.
The results of (Table 2) and (Fig. 13) reveal that oxides of magnesium, aluminum, silica, potassium, calcium, and iron are found in all samples because they represent the basic structure of potsherds [36].

(P3) Three phase model : the three phases, solid, liquid, vapor are supposed to be in equilibrium(triple point type theory) Although a lot of work have been done so far as described above, we have not yet reached the completed understanding of the melting of pure metals in small particle systems because we do not have detail information on the atomic structure and the atomic interactions in a nano-sized particle.

Pore structure.
Two models can be used to describe the MWCNT structure: Russian doll and Parchment [45, 46].
f) Including CNTs refines the structure, reduces the porosity, and can act as a bridge between the cement hydration products.

The chemical structure had an effect in the reactivity of azo dyes in redox processes as bulky group present in the o-position to the azo group made the dye defiant to oxidative degradation.
In the absence of α-hydrogen in the structure, the respective amines acted as quenchers [56].

However, in the miniaturization of photonic circuits, it is now being realized that the metallic structures can provide unique ways of manipulating light at length scales smaller than the wavelength.
Gold and silver are well known for their unique plasmonic and electronic structure properties with wide optical tenability and bio-compatibility [8].
By changing the structure and the neighboring states of doping ions, the emission characteristics of lasing glass might be achieved [47].
It is realized that, the magnitude of the third-order nonlinear susceptibility can be enhanced by modifying the local structure of these glasses through the incorporation of metallic NPs.
Nanoglass plasmonics is newly developed very vast and expanding paradigm of nanophotonics and is a unique part of physics/chemistry/materials science because it combines a wealth of scientific challenges with a large variety of near-term applications.

There are several refractories with different tasks because for different parts of reaction vessels or ladles, the properties of molten metal, slag chemistry, atmosphere, and temperature are very different from each other in steelmaking.
The rapid expansion makes structure denser preventing slag penetration.
These phases strengthen and toughen the structure to improve mechanical properties.

Nanotechnologies are the design, characterisation, production and application of structures, devices and systems by controlling shape and size at the nanometre scale.
It may be thought as a graphene sheet (from graphite) with its hexagonal structure rolled back on itself to form a cylinder.

Some of the main functions of gravel in sedimentation techniques are to hold large particles, support drainage, prevent stirring of the filter layer, and as a support for the filter structure.
Gravel helps maintain the stability of the overall filter structure, especially in gravity-based filter systems.
