Abstract: The first part of the talk is on the application of engineering principles to the development of tools for plant science and agronomy.  Most specifically in the development of model habitats that provide control over the environment of plants and, therefore, allow for the quantitative study of genome x environment interactions. As an extension to this work, we have been extending these habitats to work as nodes of physical networks of organisms (model ecosystems) where, through the use of dispersion and vortex mixing, we are able to control the effective rate of diffusion-like mass transport over three orders of magnitude. This tool enables the creation of model ecosystems where physically confined organisms can exchange chemical information, and their effective distance can be controlled by the push of a button between 400 microns and 10 cm.

The second area of research deals with one of the most significant technical issues that prevent the application of quantum dot solar cells in the market, i.e., the cost and lack of sustainability of current approaches for the synthesis of sulfide nanocrystals. The talk will describe how a simple rethinking of the sulfur feedstock allows for the creation of a new precursor, an ionic liquid formed by the reaction of H2S and oleylamine. This precursor transforms the sustainability profile of the nanocrystal syntheses by providing extremely high yields in room temperature reactions, full recyclability of unspent reagents, low externalities, low cost, and surprisingly better safety profile. If time will allow I will also discuss how these nanocrystals can be further processed by plasma processing to yield highly conductive solid state materials in one step.

Bio: U of T alumnus (PhD ChemE 0T8) Dr. Ludovico Cademartiri works with plants in engineered environments to create material solutions to develop better understandings of seed germination, plant development, and soil erosion. His lab group also focuses on nanomaterials, exploring alternative uses of plasmas in chemistry and materials science and the extension of the properties of polymers to crystals.  His Lab, the L. Cademartiri Lab, also focuses on helping students become independent, knowledgeable, creative, imaginative, rigorous, and successful problem-solvers, scientists, and professionals.
