The EU “Fit for 55” legislative package provides the introduction of regulations enabling achievement emission reduction target by 55%. As part necessary actions, it is to increase energy efficiency existing buildings. To achieve this, there are plans pace modernization buildings, from 1% 3% buildings annually 2030. However, this must be done with respect principles sustainable development, cir...

This study assessed the sustainability of two partition walls and intended to contribute Circular Economy in construction sector. A life cycle approach a multi-criteria decision support method were applied know environmental, functional, economic performances production process half-sandwich panels based on alkali-activated ceramic/slag waste cement, choosing as system boundary “cradle gate”. T...

This study reports on a Cu-sputtered film on polystyrene (PS) leading to the discoloration/degradation of methylene blue (MB) under low intensity solar simulated irradiation. Direct current magnetron sputtering (DCMS) was used to graft uniform, adhesive Cu/Cu oxides on the polystyrene substrate. The kinetics of Cu-PS mediated MB-discoloration adding H2O2 was observed to take place within 90–120...

We report a novel multi-step method for the preparation of ordered mesoporous titania scaffolds and show an illustrative example of their application to solar cells. The method is based on (monolayer) colloidal nanosphere lithography that makes use of polystyrene nanoparticles organised at a water–air interface and subsequently transferred onto a solid substrate. A titania precursor solution (t...

Polystyrene sulfonate polymer brushes, grown on the interior of the microchannels in a microreactor, have been used for the anchoring of gallium as a Lewis acid catalyst. Initially, gallium-containing polymer brushes were grown on a flat silicon oxide surface and were characterized by FTIR, ellipsometry, and X-ray photoelectron spectroscopy (XPS). XPS revealed the presence of one gallium per 2-...

The influence of substrate hydrophobicity and biomacromolecules (dextran, bovine serum albumin - BSA) adsorption on the cleanability of surfaces soiled by spraying aqueous suspensions of quartz particles (10-30μm size), then dried, was investigated using glass and polystyrene as substrates. The cleanability was evaluated using radial flow cell (RFC). The surface composition was determined by X-...
