Abstract: Global transition to clean energy relies on the development of efficient hydrogen storage materials and hydrogen evolution reaction (HER) catalysts—two primary chemistries investigated in this thesis. MXenes, a family of two-dimensional transition metal carbides and nitrides, have emerged as promising candidates for hydrogen technologies due to their high electrical conductivity, chemical tunability, and structural […] |

Abstract: Recent technical advances are leading to a rapid transformation of the chemical palette available in cells, thus making it conceivable to produce nearly any organic molecule of interest—from biofuels to biopolymers to pharmaceuticals. However, these feats require the ability to “hijack” native cellular machinery and metabolism and navigate the complexity inherent in cellular regulation. […] |

Abstract: Despite recent advances in catalytic conversion of plastic waste into high-value chemicals, the interactions between the polymers and catalysts, which are highly porous nanomaterials, are not well understood. Fundamental understanding of these interactions and the ability to modulate them would allow us to design effective catalysts for polymer upcycling reactions. To study the interactions […] |

Abstract: Electrifying the chemical industry has been much touted as a path to a low-carbon future, but nearly all pathways of interest are electrochemical reductions. If we want water-to-hydrogen, CO2-to-chemicals, or nitrogen-to-ammonia, from where will we get the electrons? Water-to-oxygen is thermodynamically expensive, kinetically slow, and generates a zero-value product. This talk will discuss two […] |

Critical to advancing immunotherapy and cell therapy in cancer is developing a deeper understanding pf the dynamics of immune cell-mediated cytotoxicity. The results from the multidisciplinary effort reported here include numerous measurements and movies of immune cell-mediated cytotoxicity with striking examples of serial killing, foraging, path-tracking, cytokine gradients at tumor margins, and killing dynamics, in […] |

Abstract: I will present the phase separation behavior of different sequences of a coarse-grained model for sequence defined macromolecules. They exhibit a surprisingly rich phase behavior, and not only conventional liquid-liquid phase separation is observed, but also reentrant phase behavior. Most sequences form open phases consisting of large, interconnected aggregates (e.g. string-like or membrane-like clusters), […] |

Abstract: Life is dependent on water: most self-assembly and binding processes of biomolecules take place in water. Water-mediated interactions are an essential driving force behind these processes, which is largely affected by the hydrophobicity of the binding surfaces. As many biomolecular binding interfaces are amphiphilic, the hydrophobic interactions are largely affected by polar and charged […] |

Abstract: We discuss how geometry, optimization, and machine learning are key technologies that are revolutionizing the way we think about data and the way we transform data into actionable models and decisions. Specifically, we explain how complex data (e.g., text, molecules, time series, images/video, supply chain flows) can be represented as geometrical objects and how […] |

Abstract: Blackouts have become rarer in the last decade. However, equipment wear and faults (some predictable)affect smaller scales but many parts of Distribution Networks (DNs) more frequently and add up to several hours of interruptions per customer per year. Also, utilities will preemptively de-energize thousands of customers in the path or vicinity of forest fires […] |

Abstract: Electrostatic assembly can be used to engineer coatings that yield release of different drugs, DNA or protein, resulting in highly tunable multi -agent delivery nanolayered release systems for tissue engineering, biomedical devices, and wound healing applications. Most recently, we have developed a modular nanoparticle approach using liposomal core particles and layering them with an […] |
