Abstract: The invention provides an In situ polymerization process which does not require the use of polymerization initiators or solvents for obtaining an electro-optical apparatus wherein a compound having a polymerizable group, preferably an acrylate or methacrylate, is introduced into a cell formed of 1 to 100 microns thick, wherein said compound having a polymerizable group is maintained at a temperature which is above its melting temperature, and a direct current electric field is applied of at least 2.5 V/?m and for a time ranging between 5 minutes and 24 hours until the polymerization of the compound with the polymerizable group is achieved, an then cooled down to room temperature and removing the applied field.

Abstract: The invention relates to a thermo-photo-bioreactor and to a method for the culture and mass micropropagation of Deschampsia antarctica in vitro. The invention comprises a discontinuous immersion reactor for biomass micropropagation, including means for incorporating chemical inducing agents (salt, metals, organic compounds, etc.) and internal luminescence or illumination means (UV radiation and temperature) for supplying said chemical inducers and/or illumination during any growth phase of the vegetable or plant material (multiplication or propagation and/or maintenance). The invention is advantageous in that it can be used to produce large quantities of biomass of the aforementioned Antarctic species, while providing conditions suitable for said plant to produce metabolites that can be used for human health and personal care.
