Abstract: A heterogeneous catalysis method for catalyzing the conversion of a first chemical species to a second chemical species includes varying a binding energy of the first chemical species, the second chemical species, or both over time and in the presence of a catalyst. Systems configured to catalyze the conversion of the first chemical species to the second chemical species by varying a binding energy of the first chemical species, the second chemical species, or both over time and in the presence of a catalyst include a sound wave generator, a pressure generator, a piezoelectric material, or a back gate device configured to facilitate the varying of the binding energy of the first chemical species, the second chemical species, or both.

Abstract: An open-channel microfluidic diode includes a first reservoir, a second reservoir, a first channel and a second channel. The first channel is in fluid communication with the first reservoir, wherein the first channel is characterized by a first cross-sectional area. The second channel is in fluid communication with the first channel and the second reservoir, wherein the second channel is characterized by a second cross-sectional area greater than the first cross-sectional area. The first channel interacts with the second channel at a junction, and wherein liquid flows from the second channel to the first channel via capillary forces.

Abstract: A manufacturing process, which we term Self-Aligned Capillarity-Assisted Lithography for manufacturing devices having nano-scale or micro-scale features, such as flexible electronic circuits, is described.
