As one of the protein fibers, wool can be damaged in its physical and chemical structure, or even dissolved [7].
JSM-5610LV SEM (JEOL Company) was used to observe the changes on surface structure of wool treated in NaOH solution [9].
At lower temperature, the hydrolysis was happened at surface layer mainly and the uneven structure of wool led to an uneven hydrolysis on the surface structure.
The extent of damage on wool surface structure can be observed clearly on SEM photos shown as Fig. 2.

Influence of Thermomagnetic Treatment on the Damping Properties and Structure of Iron-Based Alloys A.I.
The structure was studied by means of metallography, X-ray crystal structure analysis, ferromagnetic resonance, and nuclear gamma resonance spectroscopy.
The domain structure was studied by means of the powder-pattern technique.
Such a structure has a low ability to obtain during thermomagnetic treatment a magnetic structure which could be transformed more easily in case of cyclic oscillations.

Mechanical and physicochemical pretreatments address these limits by disrupting secretory structures, shortening diffusion paths, and enhancing mass transfer.
Similarly, SE applied to citrus and other oil-bearing tissues improves mass transfer by rupturing resistant structures [9,11,12,14–16].
Search, screening, and documentation followed structured review practices, with syntax adapted to each database.
SE ruptures lignocellulosic structures through rapid depressurization, dramatically increasing mass transfer but often narrowing the volatile profile.

To classify quantitatively the topological structure of all carbon fullerene molecules (fullerene graphs) we suggest a novel two-step method based on the following concept: As a first step, the duals of the fullerene graphs are generated, and as a second step, by using two molecular descriptors called Zagreb indices, we construct appropriately defined topological indices for structural characterization of fullerene isomers.
In the structural chemistry the two types of molecular descriptors called Zagreb indices belong to the family of the oldest and most studied topological invariants.
Topological indices IRMd and IRZd are indirect quantitative measures of the heterogeneity of original fullerene structures.

The oxide films of modified structure could be obtained by additional coating the foil prior to oxidation with Al or Pt nanofilms, Al on Pt or Pt on Al nanofilm laminates, or Pt+Al bimetallic nanocomposites.
Respecting the very sensitive structure of oxide films produced on FeCrAl foil, they were coated prior to thinning with a carbon film if included platinum and a platinum film if not included it.
It results from good Pt dispersion due to the increase of the crystalline structure of oxides.
