The effects of mass flow rate and subchannel configuration on
the turbulent interchange between adjacent subchannel in simulated
rod bundle were investigated.
The simulated rod bundle was made by arranging seven 1.913 cm
diameter acrylic plastic rods in an equilateral triangular pattern in a
tube 8.89 cm inside diameter.
The...
Gas mixing is studied in fluidized beds of large particles. The
bed is 0. 483 m by 0. 127 m (19 in. by 5 in. ) in cross section and has
transparent plexiglass panels on the front and back. A tube matrix
made of twenty-seven 50.8 mm (2 in.) diameter...
Desferrioxamine B (DFOB) was reversibly and covalently conjugated to polystyrene microspheres via N-succinimidyl 3-(2-pyridyldithio)propionate (SPDP) crosslinker. DFOB retained post-immobilization activity with at least 89% able to bind Fe(III)-citrate under pH 7.4 and a citrate:iron molar ratio = 100:1. Comparing iron capture by DFOB-activated beads and sulfhydryl (−SH) control beads demonstrated...
Dechlorination of 2,4,6-trichlorophenol was performed within a magnetically stabilized fluidized bed (MSFB), containing a palladized iron (Pd/Fe) catalyst entrapped within alginate beads. Kinetic parameters of this multistep reaction yielding phenol as a final product were preliminarily defined in a batch system using four different intermediates as substrates for Pd/Fe catalyzed...
Solvent extraction is an integral chemical and biochemical separation process that is drastically intensified in microfluidic systems. A novel high-throughput micro-separator was additively manufactured for the intensification of liquid–liquid separation. The micro-posts array within the flow plate generated a capillary pressure gradient on the non-wetting organic phase, enabling continuous, membrane-free,...
