Mechanics at the Mesoscale: Testing, Modeling, and Re-Engineering Living Soft Matter Abstract: Research in the Simmons Lab works to understand the feedback loop between cell-level processes and tissue-level mechanics. We have developed our own characterization equipment to effectively compare excised tissues, synthetic hydrogels, and engineered constructs. With our custom tools and models, we are studying a novel animal, the African Spiny Mouse, that is capable of […] Categories: Events and Seminars, Past Seminars |

Power-to-Gas and Hydrogen Energy Storage for a 100% Renewable Future Abstract: Renewable, ultra-low emissions and high efficiency energy conversion systems will be required to introduce energy resource and environmental sustainability. In particular the dynamic dispatch, massive energy storage capacity, and ubiquitous transmission and distribution of energy that the power-to-gas and hydrogen energy storage concepts provide will become essential to enable a 100% renewable economy. In […] Categories: Past Seminars |

Structure Genome: A Revolutionary Multiscale Approach to Bridging Materials Genome and Structural Analysis Abstract: Materials Genome Initiative (MGI) and Integrated Computational Materials Engineering (ICME) have the potential to accelerate discovery, developing, manufacturing, and deploying of advanced materials. However, it is usually not the material performance, but the structural performance or system performance we are pursuing. To fill the gap between materials genome and structural analysis, the concept of Structure […] Categories: Events and Seminars, Past Seminars |

Computational Design Optimization Abstract: Our ability to manufacture now greatly exceeds our ability to design. Engineers are no longer merely inconvenienced by inefficient trial-and-error design; rather, they are nearly incapacitated by the vast space of possible designs afforded by Advanced Manufacturing (AM) technologies. There are no systematic methods to design systems with such complexity, especially those that exhibit […] Categories: Past Seminars |

Origami Acoustics and Mechanical Metamaterials: Recent Discoveries with Adaptive Structural and Material Systems for Elastic and Acoustic Wave Propagation Control Abstract: As form follows function, so shape governs the properties of structural and material systems. Recent studies on adaptive structures have capitalized on these connections to realize unprecedented tunability of system properties and functionality by passive or active transformations of system configuration. This two-part presentation describes integrated theoretical and experimental research efforts that advance these […] Categories: Past Seminars |

Shaping Shells with Swelling Abstract: Induced by proteins within the cell membrane or by differential growth, heating, or swelling, spontaneous curvatures can drastically affect the morphology of thin bodies and induce mechanical instabilities. In this talk, we aim to describe how the differential swelling of soft materials induces a spontaneous curvature that can dynamically shape materials. The dynamics of […] Categories: Past Seminars |

The Role of Gas Turbines in Global Energy Conversion Abstract: It has been remarked that “invention is the mother of necessity” – not the other way around. Technology breakthroughs of themselves, can and do create world markets. In a very short period of history, the gas turbine, youngest of major energy conversion devices, has changed and created global markets in aviation, in marine propulsion […] Categories: Past Seminars |

Microengineering Approaches for Tissue Engineering and Developmental Biology Abstract: Early stages of human neural development include neural induction, shaping, folding, and closure of neural tubes. Current understanding of early neural development relies on animal studies. However, insights in human neural development mechanism are very limited, largely due to the inaccessibility of human embryo, lack of in vitro models, and ethical concerns. In this […] Categories: Past Seminars |

Atomistic Modeling at Experimental Strain Rates and Time Scales Abstract: I will present a new computational approach that couples a recently developed potential energy surface exploration technique with applied mechanical loading to study the deformation of atomistic systems at strain rates that are much slower, i.e. experimentally-relevant, as compared to classical molecular dynamics simulations, and at time scales on the order of seconds or […] Categories: Past Seminars, Uncategorized |

Mechanics of Blood Clots and Fluctuating Lipid Bilayers Abstract: Blood clots are required to stem bleeding and are subject to a variety of stresses, but they can also block blood vessels and cause heart attacks and strokes. We measured the compressive response of human platelet-poor plasma (PPP) clots, platelet-rich plasma (PRP) clots and whole blood clots and correlated these measurements with confocal and […] Categories: Past Seminars |
