Abstract: The present invention relates to a magnetic nanoparticle comprising: a) a core containing a ferromagnetic material; b) an outer coating containing a mixture of a lipophilic compound and a hydrophilic compound. The outer coating of the above particle makes the nanoparticle stable in water and, simultaneously, capable of adsorbing/emulsifying large amounts of hydrophobic/lipophilic compounds. The present invention further relates to a process for the preparation of the above-mentioned particles as well as their use in the removal of hydrocarbons from solid or liquid environments and metal ions from contaminated water (wastewater).

Abstract: An interpenetrating biodegradable polymeric matrix hydrogel and the use thereof to support, encapsulate, convey and release several types of cells under conditions which allow the cells to be kept alive, grow and interconnect. The hydrogel may be used to prepare implants for integrally or partially regenerating, reconstructing and/or replacing damaged, dead or no longer functional tissues, in particular at the central nervous system or spinal marrow level. In such use, the biodegradability of the hydrogel allows a progressive release of the conveyed cells in order to promote their integration, even functional, with the surrounding tissue. The hydrogel may also be employed to support cells, for example, neural cells such as neuronal cells, on measuring devices, specifically realized for monitoring several parameters of cell activity, also during pharmacological and bio-mechanical tests.

Abstract: A process is described for the preparation of carbamates of primary and/or secondary polyamines, which process comprises the steps of vaporising a primary and/or secondary polyamine and reacting said vaporised primary and/or secondary polyamine with gaseous carbon dioxide. In particular, the process relates to the production of the carbamates of hexamethylenediamine, 1,4-diaminocyclohexane and 3-aminomethyl-3,5,5-trimethylcyclohexylamine.

Abstract: The present invention relates to a process for cleaning the reaction chamber (12) of a CVD reactor, comprising the steps of heating the chamber walls to a suitable temperature and introducing a gas flow into the chamber, this cleaning process may be advantageously used within an operating process of a CVD reactor for depositing semiconductor material onto substrates inside a chamber; this operating process envisages a growth process comprising the sequential and cyclical loading of the substrates into the chamber (12), deposition of semiconductor material onto the substrates and unloading of the substrates from the chamber (12); after unloading a process for cleaning the chamber (12) is performed. The invention also relates to process for cleaning the entire CVD reactor, which envisages, together with heating, the presence of chemical etching components in the gas flow.
