Abstract: A process of manufacture of a solid catalyst made of a support coated with a thin catalytic layer and a process for eliminating gaseous and/or particulate pollutants in an exhaust gas. The process of manufacture includes preparing a solution A by dissolving alkoxide and/or chloride precursors of at least one metal selected from Al, Si, Ti, Zr, Fe, Zn, Nb, V and Ce in a solvent S1, preparing a solution B containing a surfactant, an organic acid, and/or hydrochloric acid (HCl) in a solvent S2, mixing solution A and solution B together, thereby obtaining a washcoat solution C, and dip-coating, drying, and calcinating the support into washcoat solution C. The processes provide for elimination of volatile organic compounds (VOCs), CO, and/or particulate pollutants in an exhaust gas.

Abstract: The invention relates to a process of manufacture of a solid catalyst made of a support coated with a thin catalytic layer and to a process for eliminating gaseous and/or particulate pollutants in an exhaust gaz.

Abstract: A hybrid silica bead having a millimeter scaled-size is adapted for the entrapment of a component or a bioactive substance. The bead is formed of a porous core including a hybrid alginate-silica and an external porous layer having silica and a silica concentrator. A one-pot process prepares hybrid beads for use of the beads for the entrapment of a component or a bioactive substance.

Abstract: A method is for the cryopreservation of a (plant) cell, (plant) organelle or (plant) tissue, where the (plant) cell, (plant) organelle or (plant) tissue is encapsulated in a matrix formed of an abiotic material in presence of one or more additives with cryoprotectant effect. The method provides a faster, more effective and cheaper way to cryopreserve biological material.

Abstract: Novel compositions of molecular sieve adsorbents are provided in which at least 50% of the exchangeable cations are selected from those of Li, Ca, Ag and Cu and which have within their pore system metal oxide, metal oxide precursors or mixtures thereof. These compositions are useful for the separation of gases and, in particular, the separation of nitrogen from air to produce oxygen or oxygen-enriched gas.
