Resumen:
Una universidad checa ha desarrollado y obtenido la patente de una tecnología de fabricación, activación y aumento de la eficiencia de absorbentes y fotocatalizadores y su deposición en tejidos portadores. La tecnología se basa en la organización automática de partículas activas de una dispersión de líquido congelada en sublimación controlada al vacío. En la interfaz de sublimación, las partículas se unen a nanoagregados con una superficie altamente específica, que se activan durante el proceso no solo por adsorción sino también por la deposición reactiva de películas delgadas, como fotocatalizadores. Se buscan entidades privadas interesadas en aprovechar los resultados en su actividad empresarial. El objetivo es establecer acuerdos de licencia.

Tittle:
Patented innovative technology of production, activation and the efficiency enhancement of sorbents and photocatalysts, and their deposition on the carrier textiles
Summary:
A Czech university developed a patented innovative technology of production, activation and the efficiency enhancement of sorbents and photocatalysts, and their deposition on the carrier textiles. The university offers licence agreement to the private entities which will use the results in its own business activities.
Description:
The patented technology is based on the use of self-organizing of active particles of frozen liquid dispersion in controlled vacuum sublimation. On the sublimation interface the particles are bound to nano-aggregates with a high specific surface area, which can be activated during the process not only by the adsorption, but also by the reactive deposition of thin films, such as photocatalysts. Suitable application of the process on the existing commercial sorbent materials also enables to increase their effectiveness. Industrial application of this technology is only an upgrade of the output and does not require any change within the existing production chain.
The basis of the technological process is an application of controlled vacuum sublimation in the production of nanoparticle aggregates and deposits on fibrous and textile carriers with high specific surface area.
The university offers licence agreement to the private entities (environmental protection) which will use the results in its own business activities.
Advantages and Innovations:
1. The technology allows the creation of entirely new morphology of nanoparticle aggregates with high values of specific surface area. Such nanoparticle aggregates can serve as a basis for photocatalytic filters for degradation of industry pollutants and warfare CBRN (chemical, biological, radiological and nuclear) agents.
2. The technology enables the preparation of efficient hybrid sorption materials with photocatalytic activity.
3. The technology enables to increase the sorption capacity of some standard sorption materials.
4. The technology enables to deposit the active material on the fiber of fabrics both for filters and in particular for the protection of military suits.
5. The savings are first and foremost in the cost of thermal energy activation of sorbents.

Partner sought

Type and Role of Partner Sought:
The university plans to offer licence agreement to private entities which will use the result in their own business activities. Another possibility is to found a start-up company in connection with a private investor or establish additional scientific and research cooperation with other organizations. The university offers technical assistance at the beginning of the cooperation.
By commercial outputs will be sorption and photocatalytic nanostructured materials of higher quality than a current standard materials used in practice of environmental protection. Such materials will be in the final stage in the form of a nanopowder or fibrous carriers with deposited nanoparticles of active materials.
