A 100 kg batch of product containing 10% ethanol by weight is to be dried to 0.1% ethanol by weight by passing 0.2 m^3/min of 50 degree C nitrogen through the dryer. WebAug 1, 2024 · The porous carbon could magnetically separate the dye due to the magnetic character of the metallic cobalt nanoparticles. In addition, Xu and co-workers had prepared a water-soluble and well-crystallized nitrogen-doped graphene quantum dot (N-GQD) which was obtained by using a ZIF-8-derived carbon as a source of graphitic sheets [23].
WebNitrogen doping of carbon quantum dot results in improved fluorescence performance and a wider range of applications in photocatalysis, sensor and bioimaging, etc. Herein, a water-soluble and well-crystallized nitrogen-doped graphene quantum dot (N-GQD) has been obtained by using a MOF-derived carbon (ZIF-8C) as a new source of graphitic sheets. WebA pharmaceutical product is crystallized and washed with absolute ethanol. A 100 kg batch of product containing 10% ethanol by weight is to be dried to 0.1% ethanol by passing 2 m3/min of nitrogen at 35 oC through the dryer. The dryer is operated at 35 oC and 0.1 MPa.
