Abstract: A support nanofunctionalised with photocatalytic nanoparticles made of polymeric material, preferably transparent or translucid, characterised by a nanoroughness, measured by means of an electron microscope, comprised between 10 and 150 nm and a macroroughness, measured by means of an electron microscope, comprised between 100 and 600 ?m, wherein said nano and macro-roughness are diffused internally and/or superficially. A process for preparing the nanofunctionalised support is also described. Further, an use of the nanofunctionalised support as a photocatalyst activated by UV and/or visible light, for the decontamination of a fluid, preferably air and/or water, from organic contaminants, bacteria, moulds, odours and a combination thereof is described. Finally, a filtration device comprising at least one nanofunctionalised support of the invention associated with at least one source of UV and/or visible light configured to irradiate said at least one nanofunctionalised support is described.

Abstract: Methods and apparatus for generating a private-public key pair, for encrypting a message for transmission through an unsecure communication medium (30), and for decrypting the message are disclosed. The methods are based on the well-known McEliece cryptosystem or on its Niederreiter variant. More general transformation matrices Q are used in place of permutation matrices, possibly together with an appropriate selection of the intentional error vectors. The transformation matrices Q are non-singular n×n matrices having the form Q=R+T, where the matrix R is a rank-z matrix and the matrix T is some other matrix rendering Q non-singular. The new Q matrices, though at least potentially being dense, have a limited propagation effect on the intentional error vectors for the authorized receiver. The use of this kind of matrices allows to better disguise the private key into the public one, without yielding any further error propagation effect.

Abstract: A process for reducing ammonia from digested wastes (9), in which the stripping of ammonia by counter-current air/liquid extraction inside a stripping column (1) and the subsequent recover of ammonia by counter-current contact of the gas phase (11) exiting said stripping column (1) with a first sulphuric acid solution (10) inside a first absorption column (2) are provided.
