    摘要： A thermal management system comprising: a thermal source of low to cryogenic temperature; a heating element for heating the source; a shield adapted to exchange heat by conduction to/from a sample and to/from the source; a controller calibrated for maintaining a gradient of temperature along the shield within a pre-determined range; a vacuum sealing feedthrough comprising a thermal insulator element, the vacuum sealing feedthrough delimiting around the first interface a vacuum sealed volume so that the shield exchanges heat with the thermal source exclusively by conduction and exclusively at a first interface. An exemplary purpose for this thermal management system is the sublimation of water ice and/or water ice trapped in a regolith, and positioned in a vacuum chamber. The heat insulator element is configured to separate physically the thermal source from a vacuum chamber into which the shield can protrude, so that sublimated compounds from the sample do not encounter colder point which would cause their deposition on the shield or on the walls of the chamber.

    摘要： The disclosure relates to a method for manufacturing a colloidal dispersion of Kraft lignin (KL) nanoparticles, said method comprising the steps of (a) providing KL; (b) dissolving said KL into a solvent, to obtain a solution having a concentration of Kraft lignin of at least 15 mg/ml; and (c) mixing said solution with an antisolvent under mixing conditions, to provide a colloidal dispersion of nanoparticles. Said method is remarkable in that the solvent used in step (b) of dissolving said KL is one or more organic solvents, and in that step (c) of mixing is performed by the addition of the solution of step (b) into an antisolvent being or comprising water. The disclosure also relates to spherical KL nanoparticles with an average diameter size ranging from 9 nm up to 70 nm. The disclosure further relates to various uses of said spherical KL nanoparticle.
