Fabrication techniques, disadvantages

The fuel cell types addressed in this handbook have significantly different operating regimes. As a result, their materials of construction, fabrication techniques, and system requirements differ. These distinctions result in individual advantages and disadvantages that govern the potential of the various cells to be used for different applications. 

This pumping technique uses no moving parts, however, and does not require sophisticated fabrication techniques. It is relahvely easy to implement and operate in microchannels and other miniaturized systems [287]. The disadvantage of EOF is its dependency on huid physiochemical properties (ionic strength, pH, organic content, etc.) to develop the surface charge, so its effechveness will change for each huid used in the pump [290]. 

Concerning the need to produce PUR scaffold with biomimetic architecture, different fabrication techniques are available, including both conventional and rapid prototyping techniques. Depending on the PUR physicochemical properties and final scaffold requirements, an optimal fabrication technique can be selected. Table 6.6 summarises the main scaffold fabrication techniques and their advantages and disadvantages.
