摘要:
The present invention concerns a method and a device for determining mechanical stress load, and optionally interface effects, on particles dispersed in a fluid. According to the invention, fluid comprising dispersed particles such as biomolecules is fed into a sample space of a device comprising a jacket which encloses a sample chamber and at least two rolls arranged within said jacket such that said sample space is defined between said rolls, said rolls being independently rotatable with respect to each other, wherein said jacket has an inner surface which is essentially adapted to the outer surface of the rolls, rotational movement is imparted to at least one of the rolls of said device, and changes in the state of said particles are determined from which mechanical stress load acting on the particles can be determined.

摘要:
A cyclone separator (1) has an elongated vertical housing (2), whose upper section (3) is equipped with a carrier gas/product inlet (4), a separating wheel (6), and a carrier gas/fine product discharge (7). A lower section (9) of the housing defines an oversized product discharge (11). The housing (2) has a central axially extending built-in unit (12), which separates the cyclone carrier gas/particle flow stream, downwardly in a peripheral region, and upwardly in a central region. A lower built-in unit section (14) is joined to a cylindrical middle built-in unit section (15). An entry area of the middle section (15) is equipped with a constrictor (19) which with the built-in body forms a Venturi. Finally, a secondary air supply (24) enters into a lower inlet opening (9) of the lower built-in unit section (14) facing the constrictor (19). An injector effect is achieved which increases the suction, resulting in further improvement of the separating and sorting properties.

摘要:
A method of producing from particles of a layered material platelets comprising the layered material, the method comprising the steps of: mixing the particles of the layered material in a liquid medium; and exposing said mixed-in particles to a mechanical grinding treatment, thereby exfoliating at least some of the particles of the layered material to produce platelets from the layered material. Moreover, a method of producing from particles of a layered material platelets comprising the layered material, wherein the particles are exposed to a mechanical grinding treatment using grinding media, the stress energy of the grinding media SEGM being smaller than 10 μNm.
