  Black Holes and Gravitational Waves: The Quest to Verify Einstein's Predictions

  Einstein's theory of General Relativity predicts a Cosmos with black holes and gravitational waves.  Although neither black holes nor gravitational waves have been directly detected, their presence is already felt throughout the Universe. This decade will witness observations  for which gravitational waves are the messengers that deliver information in exquisite detail about astrophysical phenomena, among them the collision of two black holes, a system completely invisible to the eyes of traditional telescopes. In support of this new gravitational wave astronomy, modeling what to expect is crucial for the success of this endeavor. Modeling sources of gravitational radiation requires solving the Eintein equations of General Relativity using the most powerful computer hardware and most sophisticated numerical algorithms. In this talk I will review these challenges, how we have overcome them, and what we have learned along the way. Our predictions of the gravitational waves from the black holes collisions is one crucial step in ushering in the new era of gravitational-wave astronomy.

  Micro/nanofluidics deal with interfacial and transport phenomena at micro/nanoscale, and they received significant attention in the last two decades largely due to their potential applications in biochemical fields. While the significant promise (aka hype) of micro/nanofluidics is yet to be
  realized as envisioned in the 1990s, the importance of micro/nanofluidic physics in practical technologies is widely recognized. Here we present two examples in which micro/nanofluidics physics play a central role in determining the viability and performance of a technology. In the first case, we examine ink-jet based bio-manufacturing, in which cells are delivered with high spatial resolution by ink-jets. While the viability of this technique has long been doubted, we show that, using scaling analysis and computer simulations, cell experiences strong but very brief
  shearing, which can explain the apparent success of the technique. By elucidating the flow physics underlying the printing process, we identify the mechanisms responsible for cell damage and suggest methods for alleviating the cell damage during printing. In the second case, we examine the capacitive electrical energy storage using supercapacitors. We show that simple interfacial physics are behind the anomalous enhancement of capacitance in sub-nanometer pores. We show that a fundamentally new regime of fluid transport emerges in the next-generation supercapacitors based on hierarchical nanomaterials, and exciting opportunities exist in harnessing the new flow physics in these materials.
