Continuous flow processes on single magnetic and diamagnetic particles in microfluidic devices
… have seen increasing interest in (bio)chemical processes in recent years due to their various surface functionalities, high surface-to-volume ratio, small sizes, and ease of manipulation via magnetic fields. However, conventional reactions and assays that use magnetic particles as solid supports …

Development of new transition metal catalysts for C-N bond formation and continuous flow processes for C-F bond formation
… the development of new methodologies and processes to form carbon-nitrogen (C-N) and carbon-fluorine (C-F) bonds. The development of methods for the formation of C-N and C-F bonds are highly important to chemistry in general and find broad application in many different areas of research. …

Engineering polymeric hollow fiber membrane reactors for sustainable chemical transformation reactions
“Over the past decade, laboratory-scale continuous-flow processes have witnessed explosive developments and have attracted a great deal of interest with respect to the significance of the economic and environmentally-sustainable production of pharmaceuticals, fine chemicals, and agrochemicals, as …

A study of the effect of dilution rate on bacterial populations
… free swimmer population were noted. An aseptic continuous flow system proved of no great advantage over that which had ambient inoculation, however, slime production did not follow identical growth patterns in three identical growth vessels. Coulter counts were made on a pure culture of B. …

Experimental and theoretical investigations of a new integrated solar tower system for photocatalytic hydrogen and power production
… lab scale system, capable of handling continuous flow processes, is built, and experiments are conducted to investigate the behaviour of this system. Production of hydrogen in the photo-reactor is observed to increase with an increase in temperature and a decrease in the pressure to …

The potential of immobilied algal cell systems for the removal of mercury from aqueous solution
… mercury from aqueous solution in batch and continuous-flow processes was inyestigated. Initial experiments showed that HgCl2 added to growth mediun. at I mgg -I r did not markedly affect the growth of non-immobilized Chiorella at io cell ml. Batch culture experiments using 203 Hg showed that …

Gravity selector-enabled kenaf recirculation and reuse as a renewable ballasting agent for sludge settleability enhancement in a municipal wastewater secondary process: A real wastewater pilot-scale study
… of these approaches. Hydrocyclone-enabled continuous flow densification has been applied for full-scale applications; however, it requires long startup times and, in some instances, results in poor stability of the densified floc. Migrating carriers hold promise to offset these …

Continuous synthesis of iron and aluminium-based nanoparticles
… and temperature. This thesis employs continuous flow processes as an alternative to standard batch processes to address the challenge raised by nanomaterial synthesis scale-up. Continuous processes are more reproducible because they provide accurate control over fluid dynamics, heat …

Continuous-flow study and scale-up of conventionally difficult chemical processes
… costs and increasing safety. Additionally, continuous flow processes allow for a large number of experiments to be performed after a single setup. These advantages were exploited to enable continuous-flow study of chemical syntheses that are hazardous or difficult to perform by conventional …

Catalyst immobilization techniques for continuous flow synthesis
Catalytic processes are ubiquitous in both research and industrial settings. As continuous flow processes continue to gain traction in research labs and fine and pharmaceutical chemical processes, new opportunities exist for implementing previously difficult catalytic transformations. The major …
