A simple, convenient, reusable, and inexpensive airand water-purification unit including a one-end sealed porous amorphous-silica (a-silica) tube coated with TiO2 photocatalyst layers has been developed. The porous a-silica layers were formed through outside vapor deposition (OVD). TiO2 photocatalyst layers were formed through impregnation and calcination onto a-silica layers. The resulting por...

The goal of this study was to investigate the effectiveness of stand-alone modular air purification systems in improving air quality in dental practices, hospital and laboratory environments. As air pollutant make-up and concentration may vary significantly in different indoor environments, the air cleaning technologies utilised should be optimised for the pollutants targeted in a particular en...

This article addresses the design of a new photocatalytically active gypsum plaster. A hemihydrate in beta type is used as binder to design this material and a carbon modified TiO2 that can be activated by visible light is used as photocatalyst. An own developed test setup to assess the indoor air purification capacity of the developed material is presented. The new product possesses the indoor...

A new easy-to-use air purification system called “A-Bios”, based on UVC radiation with the addition of special graphite filters to eliminate traces of ozone, to be used in the indoor environment has been developed in the framework of the EC financed project “An innovative technology, based on UV radiation, to strongly reduce the microbial activity of the air inside the store rooms of the cultur...
