Quantitative control over electron beam nanochemistry during liquid cell TEM

Liquid cell transmission electron microscopy (LC-TEM) has emerged as a powerful tool for direct visualization of nanocrystal nucleation and growth at high spatial resolution. Current limitations of the liquid cell sample holders necessitate utilizing the electron beam as the stimulus for initiating nanocrystal formation and other related processes like molecular crystallization, nanoparticle etching, and self-assembly. Electron beam induced chemistry has proven to be considerably more complex than conventional chemical reagents used in flask-based synthesis of nanomaterials.

Construction and Deconstruction of Three-Dimensional Molecular Architectures

Tommy was born in Linz, Upper Austria in 1983. In 2002, he moved to Vienna to study chemistry at the University of Vienna. In 2007, he joined the laboratories of Prof. Johann Mulzer and under his guidance he developed enantioselective syntheses of the complex polyketide kendomycin and echinopines A and B [Interesting tidbit: he and another graduate student worked on the echinopines without telling Prof. Mulzer; they finished the synthesis, wrote it up, and presented it to their boss.].

Agricultural Chemistry: Small molecule unsung heros

There continues to be a need for innovation in crop protection technologies to provide a sustainable food supply for the growing population.  Global food protection will require the efforts from many including industry, farmers and government agencies.  Crops, in particular, require continued protection from the pressures of disease, insects and weeds. This talk will highlight several case studies that demonstrate approaches taken within Crop Protection Discovery Chemistry at Corteva™ Agriscience to develop novel small molecules that address these challenges.
