A novel method to make reproducible defect free self-supported polyaniline films with thicknesses between 2 and 6 µm, and polyaniline nanomembranes with a selective layer thickness as thin as 300 nm supported on a porous poly-vinylidene difluoride (PVDF) structure is developed. For dense polyaniline

The surface of hydrophobic porous polypropylene membranes could be modified in such a way that it is possible to deposit catalytically active palladium on the outer surface, while maintaining the hydrophobic nature of the internal pore system. The proof-of-principle for oxygen removal from water was

The concentration of solutions containing KCl and H2SO4 in the MD membrane reactor results in the formation and precipitation of KHSO4 in the feed tank (REACTOR) whereas HCl is transferred through the membrane and pure diluted hydrochloric acid is obtained on the permeate side. The continuous remova

A membrane reactor with perovskite hollow fibres in combination with a commercial steam reforming catalyst is used to produce in a long term scale synthesis gas with a methane conversion of about 96%, a CO selectivity of 95% and at a H2/CO ratio of 2. By having the whole perovskite hollow fibre at 8

The transmembrane pressure and the temperature have a marked effect on the retention of lignin and hemicelluloses during ultrafiltration of kraft black liquor. The difference in retention was used to separate lignin and hemicelluloses.

Large fouling susceptibility was observed during both microfiltration and ultrafiltration.

Italy, with its 7.600 kilometers of coast, is full of fresh water and sea water sources to be exploited for the development and the application of this process. As nuclear energy production is not accepted in Italy at the moment, it is necessary to consider either highly polluting processes or techn
