    • The present invention relates to a new synthesis procedure for a family of silica based polymer materials synthesized through the interconnection of silicate oligomers with reactive silanes. By using this synthesis it is possible to generate novel silica based polymer materials. The present invention thus also relates to the members of this group of ordered silica based polymer materials whereby silicate oligomers are interconnected trough siloxane bridges and with empirical formulae Abx, whereby A presents the silicate oligomer, b the siloxane bridge and x the ratio between the number of silanes and the number of silicate oligomers in the material. This group of materials are particulary useful for certain applications. In another aspect, the present invention provides the use of the materials of present invention as a fire retardant coating, to enforce polymers, as a cross linking agent in polymers, as adsorbent in water purification, in separation processes, as catalyst or catalyst support in catalysis, for spin-coating of thin films, for spin-coating of thin films with low k dielectric layers in integrated circuit applications, in sensors, as (super)hydrophobic anti-ice coating on airplanes and windmills, as anti-fouling coating inside for instance in pipelines, as anti-dirt coating.

    • A device is disclosed that generates hydrogen from ambient air humidity under sunlight without any water oxidation co-catalyst (e.g. IrRuOx). The device comprises at least one semiconductor photoanode which performs the water oxidation without back reaction or deteriorated photoefficiency. The apparatus combines a photoelectrochemical process with a fuel cell for the generation of electricity. The photoelectrolysis of water to produce hydrogen and oxygen uses a semiconductor photoanode and a cathode, both comprising a macroscopic conductor, which is at least partially coated with a nanoscopic conductor. In particular embodiments this device uses an illumination controller, such a controller can be 1) an illumination intensity controller, 2) a filter for visible and infrared light to reduce dehydration or heating up and/or 3) a switch for intermittent periods of illumination of the semiconductor photoanode. In yet another embodiment the membrane electrode assembly (MEA) comprises incorporating hygroscopic silica. The preferred semiconductor material for the photoanode is TiO2 and the preferred nanoscopic conducting material is carbon nanotubes (CNT). Furthermore, plasmonic nanoparticles like silver-gold alloy nanoparticles are deposited on the layer of semiconductor at the photoanode.

    • A new family of ordered mesoporous silica materials denoted COK-10 is synthesized under mildly acidic or neutral pH conditions using a combination of an amphiphilic block copolymer and optionally a tetraalkylammonium compound. The mesopore size is substantially uniform, is in the range 4-30 nm, and can be fine-tuned by adapting the synthesis conditions. A new family of 2D-hexagonal ordered mesoporous silica materials denoted COK-12 is synthesized also under mildly acidic or neutral pH conditions using a combination of an amphiphilic block copolymer and a buffer with a pH greater than 2 and less than 8. The mesopore size is substantially uniform, is in the range of 4 to 12 nm and can be fine-tuned by adapting the synthesis conditions. These ordered mesoporous silica materials are useful as carrier materials for the formulation of poorly soluble drug molecules and for oral drug formulations for immediate release applications.
