Abstract: The present application relates to novel excitable particles which can be used in the health sector. It more particularly relates to particles which can generate electrons and/or high energy photon when excited by ionizing radiations such as X-Rays, ?-Rays, radioactive isotope and/or electron beams, and to the uses thereof in health, in particular in human health. The inventive particles are made of an inorganic material comprising oxygen, in particular an oxide, said material having an adequate density, and can be activated in vitro, ex vivo, or in vivo, by controllable external excitation, in order to disturb, alter or destroy target cells, tissues or organs. The invention also relates to methods for the production of said particles, and to pharmaceutical or medical device compositions containing same.

Abstract: The invention relates to a titanium aquo-oxo chloride and to a method for its preparation. The compound is in the form of crystals and has the following composition by weight: 26.91% Ti; 21.36% Cl; and 4.41% H, which corresponds to the formula [Ti8O12(H2O)24]Cl8.HCl.7H2O. The method of preparation consists in hydrolyzing TiOCl2 either in an atmosphere whose moisture content is maintained between 50 and 60%, or by an alkali metal carbonate A2CO3, in order to obtain a titanium aquo-oxo chloride. The compound is useful as a semiconductor element of a photovoltaic cell or as a photocatalyst in air or water purification treatments.

Abstract: The invention relates to a titanium oxide-based polymer composition. The inventive composition comprises a TiOx(OH)y(H2O)z(x+y?+z=3) titanium oxide-based polymer in the form of a gel or sol. Said polymer, which has a one-dimensional (1D) structure, is made from concentrically-wound fibers having a periodicity which is deduced from the spacing between said fibers, of between 3.5 ? and 4 ?. Each fiber comprises TiO6octahedrons and each TiO6octahedron shares two opposite edges with two adjacent octahedrons (2.times.2.92 ?) in order to form infinite chains which develop along the axis of a fiber. According to the invention, two adjacent chains form double lines as a result of the shared edges (2.times.3.27 ?). The inventive polymer is suitable for use as a photosensitive element in a photovoltaic cell, such as a sunscreen for a window.
