Exploring the Effects of Liquid in the Pore Network of Sorbent Polymer Composites on Transport and Adsorption for the Removal of Hg from Flue Gas
Abstract: Emissions of mercury, a toxic substance, from industrial flue gas stacks are regulated in many countries around the world. Several technologies are being developed to address the decreasing emission limits. W.L. Gore & Associates Inc. has developed an innovative technology, called the GORE™ Mercury Control System (GMCS) [1], for addressing this need. The GMCS is a unique fixed sorbent system that also provides SO2 removal as a co-benefit. It is based on discrete stackable modules comprised of Sorbent Polymer Composite (SPC) materials with an open channel geometry. Hg is chemisorbed from the flue gas and bound into the SPC. On the other hand, SO2 is converted to sulfuric acid filling a fraction of the SPC pores. However, due to the hydrophobic nature of the SPC, the liquid acid is expelled preventing the flooding of the entire pore network with liquid, which would have an adverse effect on Hg capture rates.
A reactor model that describes the transport & reaction steps taking place during Hg capture in GMCS will initially be presented, and will be used to highlight the importance of knowing the fraction of liquid into the SPC tape pores. Characterizing the pore network of the SPC tapes is a challenging task not only because the pore sizes span several orders in magnitude, but also because measurements need to happen at dry and 100% relative humidity conditions. Emphasis will be placed on how we combined a set of complimentary techniques (Hg intrusion, N2 & H2O physisorption, and X-ray computed tomography) to obtain a 3-D reconstruction of the dry and wet SPC pore network and how this reconstruction was analyzed to get information about the porosity and tortuosity of wet and dry SPC tapes. Finally, we will show an example of how we used this information together with the reactor model to quantify the impact of liquid in the SPC on Hg removal rate.

Cellular Phenotypes Get Physical: Lessons From Aging Lymphoma
Abstract: As we age, cells within organs and tissues undergo profound biophysical and biomolecular changes, which significantly influence the rate of functional decline in humans. Working under the premise that age-related dysfunctions at the clinical scale is related to propagated cellular defects, I will present data showing that aging information is encoded within biophysical properties of cells, and can therefore be used as robust biomarkers of aging. These findings are important as it provides a proof-of-concept, and a hypothetical framework that can be used to stratify individuals based on ageing trajectories in both health and disease. In the context of disease, diffuse large b-cell lymphoma is an aggressive and common type of lymphoma, with peak incidence in individuals 65 to 74 years old. Currently, my work focuses on a critical and understudied aspect of lymphoma biology, geared towards understanding the role of the stromal microenvironment in creating a pro-lymphoma niche. By asking questions regarding the biomolecular and biophysical properties of lymphomas, i.e. tumor mechanics, cellular and extracellular matrix (ECM) composition and architecture, and molecular information (i.e. genetic, proteomic), we gain a better understanding of how stromal re-programming and matrix remodeling shape the lymphoma microenvironment. My long term vision for this line of work is to identify exploitable targets within the microenvironment for eventual clinical implementations.
Biography: Jude is currently a postdoctoral associate at Weill Cornell Medicine in the laboratories of Leandro Cerchietti and Ari Melnick, where he studies the role of the stromal microenvironment in creating a pro-lymphoma niche. Prior to his postdoc, Jude received his PhD in Chemical and Biomolecular engineering at Johns Hopkins University with Denis Wirtz, where he developed a cell-based platform to determine the cellular age of healthy individuals based on biophysical properties of their cells. Jude also holds a bachelor of engineering degree in Chemical Engineering from the City College of New York.

“Continuous, Real-Time monitoring of Small-Molecule Therapeutics in the Body”
Abstract: Personalized drug therapy seeks to tailor treatment to the individual, taking into consideration each person’s unique genotype and metabolism to determine a dose that maximizes drug efficacy and avoids toxicity. Realizing this goal has been extremely challenging, however, for two main reasons. First, it is difficult to determine the optimal drug dose for each patient due to our limited understanding of pharmacogenetics and physiology. Second, even the most sophisticated drug delivery approaches fail to account for hour-to-hour fluctuations in an individual’s metabolism driven by changes in health status, diet or drug interactions. Thus, there remains a pressing need for technologies supporting the real-time, in-vivo monitoring of drugs that would enable patient-specific, metabolism-responsive dosing. In response to this need, our laboratory pursues the development of reagentless sensing approaches that support continuous molecular measurements in the body. During this talk, I will describe an electrochemical approach that relies on DNA aptamers to perform real-time monitoring of small molecule targets, and the use of this approach to study pharmacokinetic changes in rats that originate from biological and metabolic variability.
Biography: Netz Arroyo is an Assistant Professor in the Department of Pharmacology and Molecular Sciences at the Johns Hopkins University School of Medicine. He has secondary appointments with Chemical and Biomolecular Engineering, Biochemistry, Cellular and Molecular Biology, and the Chemistry-Biology Interface programs. He received his B.S. in Chemical Sciences from Tec de Monterrey (Mexico), his Ph.D. degree in Analytical Chemistry from the University of Texas at Austin, and his postdoctoral training in Bioengineering from the University of California Santa Barbara. Dr. Arroyo’s research focuses on the development of electrochemical biosensing platforms that enable continuous, real-time measurements of specific molecules in the body. His lab employs such sensors to study molecular transport of therapeutics across biological barriers in vivo, and to develop decentralized, high-precision diagnostics for health care monitoring.
