The main contents are based on science and technology, but these have been developed and implemented by the young students of the college.
Using the steps and the process, students can start to make a real 2D codes with various materials.
They started the preparation of collecting materials and devices (magnets, projectors and so on).
In this activity, requested skills are how to make a Data Matrix in some useful material and/or media.
Through the project year, the teaching materials has been considered and developed for the students who learn the technology of image processing for the tag code inspections.

.), prossessing very high characteristics, creates a new class of nanostructured materials polymer/2D-nanofiller [4].
In conformity with this principle nanomaterial is such material, in which a fraction of division surfaces in total volume of material makes up 50 % and more.

Researchers are looking into bio composite materials because of escalating environmental concerns like the greenhouse effect and a desire in using sustainable materials [2].
Researchers in the field of materials science often use the storage modulus (also known as E0) to determine the composite's degree of stiffness.

The development of materials with specific properties is a relevant engineering topic.
The composite materials, hybrid of metal structures embedded in polymer matrices, are intensively used in mechanical systems in order to obtain materials with high resistance associated to low weight.
In order to produce this material, techniques were developed that allowed the union of the component materials.
