Advances (and limits) in photocatalytic building materials

Diamanti M.V., Politecnico di Milano, IT

Titanium dioxide has often been indicated as emerging technique for environment depollution, specially in urban environments. It can be easily added to building materials, such as concrete or mortar elements, or as coating to any [...]

Development of Durable Nanostructured Superhydrophobic Self-Cleaning Surfaces in Glass Substrates

Jiang Y.D., White M., Hunt A.T., Kitada M., Fitz T., nGimat Co., US

Superhydrophobic self-cleaning surfaces have wide applications in architectural and automotive windows and solar panels, etc. Many existing hydrophobic coatings either have low transmittance which is not suitable for windows or not as hydrophobic as lotus [...]

Influence of pigments on the photoactivity of TiO2-containing colored mortars compared with white mortars and sol-gel TiO2 application route

Diamanti M.V., Del Curto B., Ormellese M., Pedeferri MP., Politecnico di Milano, IT

In previous works, TiO2-containing commercial mortars were proved to show photoactivated properties due to the well-known semiconducting structure of titanium dioxide in anatase form. Anatase was added to white mortars in form of suspension or [...]
