Title of Talk: X-ray visions: Exploring materials function at the energy frontier

Abstract: Our need for clean energy drive widespread materials research. Breakthroughs can be driven by discoveries of new materials or advances in the tools that we use to understand how these materials function and fail. We exploit advanced characterization tools to probe the atomic structure of energy materials in situ, as they function or react. This allows us to identify how their functional behaviors are governed by their structure and chemistry. These fundamental insights serve as a road map towards a next-generation of clean energy solutions. This presentation will describe recent insights into the structure-function relationship in energy-relevant materials derived from operando high energy synchrotron X-ray scattering and pair distribution function analysis.

Title of Talk: Exploring the solid form landscape - Old tools, new tricks

Abstract: Exploring the solid form landscape of a given molecule efficiently and thoroughly is a vital part of the pharmaceutical development pathway. In order to identify the best solid form (salt, cocrystal, polymorph, hydrate etc.) to progress to later stage development you must first identify the forms that can be obtained. Common approaches to solid form screening typically employ ‘traditional’ methods such as cooling and evaporative crystallization, and have been responsible for the isolation of a wide range of novel solid forms. However, recent studies have shown that ‘non-traditional’ techniques can complement the solid form screening process by providing access to otherwise unobtainable solid forms. We will discuss the use of high pressure, other non-traditional techniques and their use in the discovery of new solid forms.

Title of Talk: Development of Ultramicroporous Metal-Organic Frameworks for Highly Selective Carbon Dioxide Separation

Abstract: An ultramicroporous metal-organic framework, Cu-F-pymo, has been studied for highly selective inverse separation of CO2/C2H2, which is very challenging to develop CO2-selective adsorbents considering CO2 and C2H2 are almost in identical molecular dimensions and physical properties. The partially-desolvated Cu-F-pymo can exclusively capture CO2 over C2H2 with very high selectivity under ambient condition. Sorption experiments and modeling studies revealed that such molecular sieving effect is attributed to the suppression of C2H2 adsorption from the blockage of the preferential sites for C2H2 by residual water molecules. The inverse separation was further confirmed by column breakthrough studies given that highly pure acetylene (>99.9%) can be directly harvested. This report highlighted the importance of pore modification by controlling guest occupation within MOFs, which will pave a new way for development of advanced porous materials for adsorptive gas separations.
