Figure 3. (a) Fabrication of
Cu3(PO4)2@magnetite thin
film (Cu@MF) and
Cu3(PO4)2@magnetite
nanoflower (Cu@MNF) in a biphasic system of toluene and phosphate buffer
saline (PBS) in a hemispherical base quartz tube, 20 mm OD, 17.5 mm ID.
(i) Schematic for the creation of Cu@M composites in a VFD. Oleic
acid-coated magnetite nanoparticles were disseminated in the toluene
phase with all experiments using a 1:1 mixture of toluene and PBS, with
CuSO4 then added quickly, followed by VFD processing at
7500 rpm. (ii) SEM of Cu@MF formed at the toluene/PBS interface, while
Cu@MFN present in the PBS phase. (b) The reaction of
2-acetamido-3,4,6-tri-O-acetyl-α-d-glucopyranosyl chloride with
4-nitrophenol in the absence of a phase transfer catalyst in an aqueous
sodium hydroxide solution and dichloromethane, with the yield of the
product plotted as a function of tilt angle and rotational speed of a
quartz tube, for either a flat or hemispherical
base14. (a-b) Reproduced under the terms of CC BY 3.0
