Ghassoul, a unique mixture of stevensite and sepiolite, comes from the only known deposit in the world, Jbel Ghassoul in Morocco. Ghassoul was found to be very good adsorbent of metal and organic pollutants and it can be also used for the preparation

Settled road dust was examined to detect the presence of non-airborne submicron and nano-sized iron-based particles and to characterize these particles. Samples were collected from a road surface near a busy road junction in the city of Ostrava, Czec

TiO2/SiO2 composites were produced as photocatalysts both by hydrolysis of TiCl4 and from TiO2 suspension prepared by hydrolysis of TiCl4. TiO2/SiO2 composites were dried at 70 °C and calcinated at 400 °C and 600 °C to investigate the effect of ca

After a friction process several changes in phase composition of friction composites are often registered. High temperature, accompanied by high pressure induced during braking can cause initiation of chemical reactions which do not run at room or el

The paper addresses the wear particles released from commercially available "low-metallic" automotive brake pads subjected to brake dynamometer tests. Particle size distribution was measured in situ and the generated particles were collected. The col

Apart from the service conditions during the braking (e.g. applied pressure, velocity of rotor) the friction-wear properties of friction composites used as a car brake lining are directly influenced by their composition. Among the components used for

The effects of alumina (Al2O3) as an abrasive on brake friction performance and friction layers of nonmetallic brake friction materials were evaluated. Five experimental compositions containing from 0 to 14.6 vol% alumina were tested (Al2O3—0, 3.4,
