“…It has been used not only to reduce the number of experiments, but also to analysis the sensitivity of parameters for passive micromixers [26], to optimize geometric characteristics of a grooved micromixer [27] and to design an active micromixer [28]. In this work, we adopt numerical simulations and the Taguchi method to investigate the effects of geometrical parameters on the performance of micromixers with micro-scale…”

“…However, under a practical point of view, to optimize the design of a SHM and therefore achieve a high mixing performance with the lowest pressure drop possible, some structural parameters have been demonstrated to play an important role (Cortes-Quiroz et al 2010). The ratio between the groove width w g and groove pitch in direction perpendicular to the walls of the grooves λ (w g /λ), was calculated to give the highest mixing performances at a value of 0.75, taken into consideration limitations due to materials and fabrication issues (see Fig.…”

Microreactors are a wide class of devices that are currently playing a prominent role in several research fields such as biology, medicine, food chemistry, environmental analysis, up to the production of compounds in organic chemistry. Several typologies of microreactors have been produced with tubular or planar shapes, of different materials and designs. In this chapter, an overview of planar microchannel-based microreactors and their application to organic chemistry is given. Initially, after recalling the main theoretical parameters of microfluidics, an introduction of the proposed technology and the main requirements to perform mixing, which is essential to perform chemical synthesis on-chip, is presented. Silicon and glass microreactors, the most common planar systems for organic chemistry, are described with the aim of pointing out the most important parameters to be taken into consideration in the planning of a specific microreactor to be used for mixing, purification or crystallization of chemicals at the microscale. Then, several applications of initially described microreactors to organic chemistry for research applications are given. In the next section, the use of planar microchannel microreactors in the field of radiochemistry is reported. The radiopharmaceutical application is not casual, being a sector in which the microreactor technology is very promising, due to the need of quickly producing small and fresh amounts of products in a controlled environment. Finally, for completeness, other approaches beyond planar microchannels are mentioned: mesoreactors towards industrial level synthesis and micro-vessels for radiochemistry.

“…But along with the rapid development in technology design, these challenges can be overcome by involving the multi-objectiveoptimization techniques. These techniques can help the designerto solve various problems in the field of engineering design.With these advantages, multiobjectiveoptimization techniques have been used to solve the design problems in some recent studies which are applied for the complex mechanical structures [1], mold of the automotive interior component [2], geometry of the groove micro-mixer [3], boiler combustion process of power plant [4], heating/cooling channels of injection molding [5], geometry of heat exchanger system [5], and airfoil of wind turbine [7].…”

Multi-objective optimization of the structural design of double end beam load cell had been performed using a genetic algorithm. Two design variables were used to minimize the structural mass, to maximize the structural strength, and to maximize the level of measurement accuracy. Based on the optimal results, the weight reduction of the structure was successfully achieved of about 8.6%. The design safety factor reached 24 % larger than the yield failure criterion. Therefore, the structure will certainly secure against the plastic deformation. The accuracy of measurement of the load cell was predicted to reach the category of high accuracy due to the amount of strain on the strain gauge cavity managed to exceed ± 1600 με.
