Abstract: The present invention relates to a method for producing a support at least micrometric in size, photocatalytically active and at least in the visible range, containing nanocrystals each composed of from 80 to 100 mol % of TiO2 and from 0 to 20 mol % of at least one other metal or semi-metallic oxide, comprising the following steps, from an acidic aqueous reaction medium, at a heating temperature of between 20 and 60° C.

Abstract: A method of date-stamping reception of digital data of a signal coherently modulating the carrier or sub-carrier, and utilizing the properties of such a modulation to improve the date-stamping thereof. Thereby accurately correcting the date-stamping of a pilot sequence (known pattern), and reducing the variance on the date-stamping of the transitions of the bits.

Abstract: The invention relates to a method of date-stamping reception of digital data of a modulated signal, said signal resulting from the modulation of a carrier or sub-carrier by a digital signal, the bitrate of symbols of the digital signal being an integer sub-multiple N of the frequency of the carrier or sub-carrier, said method comprising the steps consisting in: —coherent demodulation by means of a phase loop of a plurality of samples sm(k) of the modulated signal and obtaining of a plurality of demodulated samples sdm(k) and of the phase of the reconstructed carrier; —association of the plurality of demodulated samples sdm(k) with the simultaneous phase ?(k) of the reconstructed carrier —determination of a plurality of dates of passage to a determined value ?0 of the phase of the reconstructed carrier, relative to the date of reception of at least one sample sm(k), according to a time shift during which the carrier rotates from ?(k) to ?0.
