Abstract

The invention relates to a viscoelastic material characterised in that it is produced by recovery of the hydrophobic phase obtained by a method of hydrothermal liquefaction from a biomass comprising at least one microalga and comprising at least 40 wt.% of water in relation to the total weight of the biomass, said hydrophobic phase comprising a viscoelastic oil and solid residues, wherein the quantity of solid residues amounts to between 15 wt.% and 30 wt.% of the total weight of the hydrophobic phase.

Abstract

The invention relates to a method for locating a radionuclide emitting positons and having a child core emitting a photon by de-excitation, that comprises detecting a radionuclide response line (16) using a positon-emitting tomography camera. According to the invention, for each of the arrangements ordered by pairs of first and second interactions (Im, In) of the Compton type detected by a Compton telescope, the method comprises determining the angle (θmn) between the direction of the incident photon of the first interaction (Im) and the geometrical axis connecting the position (Pm) of the first interaction (Im) with the position (Pn) of the second interaction (In), determining the half-aperture cones (Cmn) of the angle (θmn) in which the geometrical surface does not include an intersection with line (16), selecting at least one cone (Cmn) in which the geometrical surface includes an intersection with line (16), selecting the radionuclide position from said reconstructed intersection of the response line (16) with the geometrical surface of the selected cone (Cmn).
