DSSC structure consists of dyes, TiO2 semiconductors, and electrolyte solutions between the working electrode and the counter electrode coated on a glass substrate [4].
Other studies have reported that peak broadening also indicates the formation of a porous structure.

In 3D printing, it is possible to print porous internal structure in the part.
The porosity of the structure decrease with the increase of infill percentage.
The increase in strength with the increase in infill percentage is due to the reduction in porosity in the structure as the percentage of infill increasing.

Introduction Hydrogels are widely studied in biomedical engineering as platforms for controlled drug delivery due to their three-dimensional network structure, high water content, and responsiveness to stimuli like pH and temperature [1, 2].
Future studies will assess the mechanical properties and stability of the hydrogel post-sterilization, particularly for autoclaved samples, to evaluate any impact on polymer structure or long-term stability [14].

This powder structure displays higher sinterability and allows the onset of the sintering by activated surface (SAS) consolidation process, directly leading to porous cermets with good properties.
One can see there are some particles embedded under metal layers or incrusted on them at a very texturized structure.
The annealing of row powders leads to less crystalline material in the forward milling sequence through the development of a defective structure.

This was presumably because the ultrasonication process produces a vibration that can damage the microbial cellulose structure.
This situation shows that the bonding structure in all forms of microbial cellulose that are produced does not change even though there are differences in the process of reducing the fiber size of microbial cellulose.
This vibration causes the structure of the nanocellulose to stretch, as seen from the nanocellulose fibers which are processed more thoroughly before ultrasonic (Figure 5a and 5b) and after ultrasonication, the suspension of nanocellulose produces single fibers (Figure 5c).
