Nanoscale precursors have been found useful in thin film generating for a variety of applications, from optoelectronics to medical devices. When endowed with adequate functionality, nanostructured chalcogenides are readily dispersible in various solvents to create colloidal solutions. Such dispersions, often called inks, could be easily coated in large areas on conducting substrates, conferring an inexpensive and robust method to construct thin films that could be useful in a plethora of applications, including energy generation; specifically, in thin-film photovoltaics. The processing required for obtaining uniform and dense nanostructured coatings is governed by the ability to tailor particle size, particle size distribution, nanoprecursors' surface and to select appropriate dispersion reagents. Each type of nanostructure is unique, and finding a specific set of conditions requires an in-depth analysis of properties such as surface identity and morphology. With melting occurring at several hundred degrees lower than the melting point in bulk, the thermal treatment of NP precursors enables fabrication of uniform, crystalline thin-films on inexpensive substrates which only sustain moderate processing temperatures. The operating hypothesis is that the final crystalline film will mirror the nanoprecursors composition prior to the thermal treatment. Therefore, tremendous efforts have been reported toward rigorous control of nanoparticles composition.
The presentation will outline our discoveries in the synthesis of nanostructured materials for thin-film chalcogenide photovoltaics (PV), including Cu2ZnSnS4, Fe2GeS4, and Cu3VS4, and will dive into preparative methods for a new class of materials, 2D chalcogenides, the focus of our most recent endeavors.

Kit Chapman will tell the thrilling history of creating elements past uranium - from the first steps during the Manhattan Project to the modern experiments rewriting our understanding of the chemical world. From flying planes into mushroom clouds to some of the most powerful research machines in the world, this will reshape everything you think you know about scientific discovery. Kit will also discuss his own path to becoming an author and science journalist, and give tips and advice for those who want to write their own scientific tales.

The Kritzer Lab uses innovative molecules to block disease-associated proteins, often in ways
traditional "drug-like" molecules cannot. Several projects are exploring new ways to
synthesize and screen constrained peptides, which are molecules with unique abilities to bind
protein surfaces and block protein-protein interactions. Discovering new bioactive molecules
is only the first step. however. In several other projects, we are exploring new methods for
measuring cell penetration, which is the most difficult roadblock for many emerging
therapeutics including peptide therapeutics, protein therapeutics, RNA therapeutics, and gene

My group creates electroanalytical techniques and strategies to control materials and interfacial reactivity for applications in energy storage and conversion. In this seminar, I will discuss how new polymeric and low-dimensional materials, as well as an expanded electroanalytical toolbox for understanding interfaces and nanomaterials, are allowing us to discover new synergies at the nano- and mesoscale for emerging battery technologies. I will describe systems where nano-scale heterogeneity has an impact on macro-scale battery performance. A first case involves the use of novel redox active polymers (RAPs) for size-selective flow batteries. Our highly collaborative work in this field takes place within the Joint Center for Energy Storage Research, and is aimed at discovering new chemistries for energy storage beyond lithium-ion. Our investigations on RAPs span across several areas of knowledge, from the interrogation of individual polymer particles, to the elucidation of new redox polyelectrolyte dynamics, and to the evaluation of flow battery performance. A second case involves the creation of techniques to better understand intercalation on 2D nanomaterials and their complex interfacial behavior. My group has introduced scanning electrochemical microscopy (SECM) methods that uniquely probe electronic and ionic processes. Using these and other tools, we are starting to understand fundamental balances between electrons and ions that we hope will have an impact on diverse energy conversion and storage technologies.
