CHARACTERIZING MICRODROPLETS TO UNDERSTAND THEIR UNIQUE CHEMISTRY
Abstract
Microdroplets, approximately two-tenths of a human hair or less in diameter, have shown incredible promise in accelerating rates of chemical reactions. Tiny droplets speed up what might take hours or days, to milliseconds or less, often without the use of harsh acids, expensive catalysts, or applied electric potential. These results are suggestive of avenues for greener chemistry. The capabilities of these microdroplets are directly related to their size, with increased surface-tovolume ratios correlating to greater acceleration. This makes careful control and measurement of the microdroplet size distributions essential to understanding their unique chemistry. With the purchase of a Sympatec HELOS-BR, which detects how light is scattered by a spray of droplets, we would be able to obtain the size distribution in a simple and quick manner. Such information would complement our existing efforts to elucidate reaction mechanisms in microdroplets, as well as to scale-up our spraying systems to synthesize semi-preparative quantities of products.
