Metric Options: CountsSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Conference Paper Description
Nanoparticles with metal-organic framework (MOF) structures are emerging advanced materials with exceptional internal structural and external surface properties. Particles with MOF crystalline structure can be synthesized with the conventional solvothermal methods using a metal salt and an organic ligand dissolved in a solvent in proper ratios to prepare a precursor solution. Precise control of the concentration of the precursor solution and the thermodynamic conditions, such as the temperature, pressure, and volume of the reactor, is critical in obtaining the desired MOF structure, but difficult for systems in bulk amounts. Droplet-generating microfluidic devices offer a controlled environment and inherent compartmentalization. Heat and mass transfer is dramatically enhanced at the microscale. In this study, we comparatively investigated the synthesis of zirconium(IV)-based UiO-66 nanoparticles using both a macro-scale batch reactor and a droplet-based microfluidic system. The resulting products from both the macro and micro scale systems were analyzed using XRD and SEM. We determined the recipes and the residence times that yielded UiO-66 nanoparticles with a size less than 100 nm at 100 °C. We found that more concentrated precursor solution recipes reduce the time required for nucleation and crystal growth, which is favorable in the microfluidic system.
