Nanotechnologies allow today many applications for the architectural sector through the presence on the market of innovative products for the treatment of surfaces and smart materials for building construction. In the recent years, various valid applications of nanotechnology for the conservation and restoration of cultural heritage have also emerged, revolutionizing the traditional methods.

The state of the art of the ongoing researches and of existing nanostructured products will be presented, illustrating the main principles and characteristics of interventions on historical materials through the use of nanotechnologies. These innovative technologies appear as groundbreaking and promising tools, able to improve the procedures for intervention, overcoming the major deficiencies that characterize some of the traditional techniques currently used, also allowing a more reliable and sustainable preservation of artifacts. In particular, will be discussed formulations based on the use of substances aimed at the consolidation of mural paintings and stone surfaces, such as those using CaOH, showing high compatibility with historical matters. Other examples describe nanostructured cleaning systems for the removal of polymeric coatings previously applied and high retention gels for treatments with organic solvents.

The main advantages of using nanostructured products in architecture and cultural heritage preservation fields are also pointed out, in terms of greater reliability over time and sustainability, being non-toxic and environmentally friendly treatments, also considering the reduction of the environmental footprint of the built environment throughout the efficient use of resources.

Finally, this contribution underlines that, even if these nanomaterials are contributing to a significant change in our life, we must ensure that the potential risks are identified and controlled, through developing new appropriate standards and codes for their application.

Proteins are attractive building-blocks to create complex nanomaterials. However, the difficulty to control their assembly across scales has hindered their functionality. Studying the interactions between peptides and proteins opens the possibility to identify molecular processes that can be used in innovative ways to generate materials with novel properties. Following this principle, we explore the possibility to use peptides to hierarchically guide protein conformation to bioengineer functional materials of improved complexity. The talk will first provide an overview of novel fabrication platforms to create bioactive membranes for bone regeneration and a novel 3D printing technique to create molecular patterns within 3D hydrogels. Then, I will focus on a novel dynamic system emerging from the conformational modification of an elastin-like protein by a self-assembling peptide amphiphile. This molecular interplay leads to a distinctive nanoarchitecture that can be maintained in non-equilibrium for substantial periods of time and enables the formation of robust macrostructures that display a wide range of dynamic properties including the capacity to undergo morphogenesis into desired shapes with spatio-temporal control. The functionality of the system was demonstrated by creating vascular-like structures that supported growth of vascular endothelial cells and adipose-derived stem cell.

Dzięki funduszom POKL UDA – POKL.04.01.01-00-100/10 "Chemia, fizyka i biologia na potrzeby społeczeństwa XXI wieku: nowe makrokierunki studiów I, II i III stopnia" odbędzie się szkolenie TRIZ, wraz z otrzymaniem świadectwa kompetencji wydawanej przez instytucję MATRIZ mieszczą się w Nowym Jorku.

Dla uściślenia: TRIZ to algorytm rozwiązywania innowacyjnych zadań. Brzmi to trochę jak oksymoron jednakże nie jest tak absurdalne jak wygląda na pierwszy rzut oka.

Zdelokalizowane rodniki organiczne są atrakcyjnymi elementami strukturalnymi nowoczesnych materiałów organicznych. Ze względu na stosunkową łatwość ulegania reakcjom redox oraz szeroką absorpcję w zakresie widzialnym, niektóre stabilne rodniki heterocykliczne są badane pod kątem zastosowań w spintronice, jako materiały wykazujące właściwości półprzewodnikowe i fotoprzewodzące oraz jako organiczne materiały magnetyczne.
