Abstract: The present invention relates to a method for obtaining a population of white/brite preadipocytes from precursor cells comprising the step of selecting cells for the expression of mesenchymal stem cell antigen 1 (MSCA1). The invention also relates to a method for obtaining brite adipocytes.

Abstract: An evaporation cell for evaporating a material onto a substrate placed in a vacuum deposition chamber, includes an inner enclosure delimiting an evaporation chamber for receiving a crucible containing the material and having an opening for inserting the crucible into the evaporation chamber; evaporation elements placed at the periphery of the inner enclosure for placing the crucible in evaporation conditions; an injection duct for transporting a flow of vapour of the evaporated material from the evaporation chamber to an injector located in the vacuum deposition chamber; and a stop valve placed on the injection duct. The evaporation cell includes insertion opening/shutting elements that have an open configuration for inserting the crucible into the evaporation chamber, and a closed configuration for confining the evaporation chamber in communication with the vacuum deposition chamber via the injection duct, and opening elements to provide an evaporation opening in an envelope of the crucible.

Abstract: A method for reloading an evaporation cell intended to evaporate a material onto a substrate placed in a vacuum deposition chamber, a first crucible containing the material to be evaporated being engaged with an evaporation chamber of the cell, and elements for placing the first crucible in conditions of evaporation to generate a flow of vapor of the material, the method including: loading a second crucible containing the material to be evaporated in a loading chamber previously isolated from the adjacent evaporation chamber, the pressure in the loading chamber being then substantially higher than that in the vacuum deposition chamber; confining the pressure inside the loading chamber to a level comparable to that of the evaporation chamber during the evaporation of the first crucible; transferring the first crucible to the loading chamber, engaging the second crucible with the evaporation chamber, and placing the second crucible in conditions of evaporation.

Abstract: The present disclosure relates to a networking device, a system and a method for the creation of a portable proximity communication network. A networking device comprises a communication interface and a networking component for establishing connections of the networking device, via the communication interface, with any one of a plurality of communication devices. The networking component is capable of establishing a connection with a peer networking device for creating a long range based communication network.

Abstract: An injection system for an apparatus for depositing thin layers by vacuum evaporation includes a container (4) for receiving a material to be evaporated, container heating elements adapted to evaporate the material, at least one injection ramp (1) including an inner conduit connected to the container so as to receive the evaporated material and a plurality of nozzles (3), each nozzle including at least a communication channel so as to diffuse the evaporated material into the vacuum evaporation chamber. The injection ramp (1) includes a plurality of injection modules (2a, 2b, 2c, 2d, 2e) mechanically connected to each other in series along a longitudinal direction (5), each injection module including a plurality of injection nozzles, and the injection ramp includes elements for adjusting the orientation of the injection modules about the longitudinal direction so as to align the injection nozzles along a line parallel to the longitudinal direction.

Abstract: An evaporation device for a vacuum deposition apparatus includes a crucible to contain a material to be evaporated and a bottom, a body and an opening, and a heating element surrounding at least partially the crucible body, the evaporation device being placed inside a chamber with pressure <10?3 mbar. The device also includes at least one thermal shield between the crucible body and the heating element, the thermal shield including at least one element movable with respect to the crucible and designed so the heat received by the body of the crucible at a considered point of this body conforms, at a given instant of time, to a non-constant function of the distance between the considered point and the bottom of the crucible, this function being adjustable as regards at least one degree of movability of the first element of the thermal shield with respect to the crucible.
