Pristine nanodiamonds (NDs) obtained by detonation, or functionalized by different treatments, namely oxidation, hydrogenation and amination, were used to synthesize composites by insertion in TiO2 matrixes. The different treatments of the NDs lead t

In this study, the Henry's law methodology is applied to predict the release of odorants present in single and multicomponent fragrance mixtures diluted in mineral oil, a simplified matrix used in cosmetic products. To attain this goal, the experimen
We have developed recently an indirect proof of concept (POC) of magnetic classification in wet mode. This POC, was accompanied by another one, concerning fundamental background theory and simulations. Both POC's proved the feasibility of the process

The treatment of leachates as pollutant concentrated wastewaters, is still an open issue, and although several different methods are applied for this goal, we are still far way from obtaining low-cost and at the same time efficient processes. Even fo
