acest nou concept încercă să reunească principii tehnologice noi<br />
care să conducă la armonizarea criteriilor de performanţă<br />
economică a organizaţiilor productive cu criteriile de protecţie a<br />
mediului şi a omului;<br />
- noile procedee şi produse să nu depăşească restricţiile ecologice<br />
existente, să nu modifice esenţial tehnologiile industriale de<br />
prelucrare a pieilor naturale<br />
- să conducă la eficientizări de natură economica.<br />

Neural networks are used for the modeling of the non-linear<br />
structure-properties correlations (direct problem), while the<br />
opposite problem regarding molecular design is solved using the<br />
same optimized neural networks based on genetic algorithms;<br />
considering the goal of obtaining specific properties, such as<br />
good thermal stability, we created molecular structures that<br />
could have such properties. The problems arising from and<br />
related to molecular design are difficult and complex, and<br />
therefore they need combining various types of artificial<br />
intelligence techniques. When discovering new properties, the<br />
thermal stability of synthesized materials is one of the most<br />
important requirements, and the main purpose of this innovative<br />
study is therefore molecular design using different artificial<br />
intelligence tools, such as specific materials having liquid<br />
crystal properties and good thermal stability. Since<br />
thermotropic liquid crystals are materials in which the<br />
sequencing property in liquid crystal structures occurs within a<br />
specific temperature range and it involves system temperature<br />
increase, it is easy to understand the vital role played by thermal<br />
stability in these compounds. Molecular design contributes to<br />
the creation and development of new materials, with liquid<br />
crystal properties and considerably lowers time consumption,<br />
which means important money savings, since the syntheses may<br />
be conducted so as to achieve the desired properties.<br />
