Ghost in the Machine—Translating New Technologies into Next-Generation Neurodevices

Modern neurodevices are rapidly expanding their footprint in research and clinical care. As science and technology advance, so is device complexity: hardware, software and the systems that unite them.  In this lecture I review the current state of neuro and bioelectronic devices, and provide a vision for how new materials and hardware will seamlessly integrate with state-of-the-art algorithms and systems to improve quality of life. Cost, complexity, robustness and “plasticity” are themes we will discuss, as we envision devices of the future and their role in modern health care.

Nanoengineered Materials for Advanced Energy and Water Technologies

Nanoengineered materials have exciting, untapped potential to improve energy and water technologies. In this talk, I provide a few examples of how we leverage nanoscale manipulation capabilities to develop advanced thermal management, solar thermal energy conversion and water harvesting devices. First, I discuss our recent work that harnesses novel surface designs to control and manipulate wettability and liquid-vapor phase-change processes. We demonstrated high flux evaporation from ultrathin nanoporous membranes and nanostructured surfaces that can repel liquids even during condensation. Next, I discuss how nanoengineered materials can also be used to increase the efficiency of solar thermal devices. Specifically, I share our work on nanophotonic solar thermophotovoltaics and optically transparent, thermally insulating aerogel solar receivers. Finally, I present a water harvesting device that leverages the unique properties of metal–organic frameworks and other adsorbents to address water scarcity challenges in arid climates.

Using Materials Science Concepts to Design New Drugs

Viral diseases kill millions of people every year, mostly in developing countries. We need efficient drugs to fight them when vaccines fail. To date, only a handful of antivirals have been developed. I will show that it is possible to use Materials Science concepts to design a whole new class of antiviral drugs. Viruses can be viewed as the self-assembly of many biological components. It is possible to design nanoparticles, macromolecules, and simple molecules that target specific parts of the viruses (the viral attachment ligands). I will show that, in these materials, the presence of long hydrophobic, flexible arms induces irreversible damages to the self-assembled virions upon binding, rendering them non-infective permanently. The design principle underlying this effect is the hydrophobic contact between the drugs and the virions that results in a locally applied pressure. Results in vitro, ex-, and in-vivo against a number of viruses will be discussed.

Engineering 2D Heterostructures with a Twist

The past few years have seen exciting new opportunities emerging from simply stacking and/or twisting together atom tick layers of the same or different materials. The lattice mismatch or rotational misalignment introduced by such stacking gives rise to long-range Moire patterns that lead to modification of the electronic band structure. This leads to the appearance of unexpected properties, such as Mott-like behavior and superconductivity, even in weakly interacting systems such as graphene. In this talk I will present some recent efforts in my group on twisted and strained graphene and TMD heterostructures as a function of twisting angle and gating. By using angle-resolved photoemission spectroscopy, I will discuss the effect of such misalignments on their electronic structure and discuss what are the key parameters that lead to the onset of strong correlation and novel behavior in these materials.
