Peter B. Littlewood, Ph.D., Professor of Physics at the University of Chicago; former director of Argonne National Laboratory, and founding executive director of the Faraday Institute
In 1815 Michael Faraday was gifted a voltaic pile – the first battery. He embarked on a series of experiments that led to the electrical dynamo and the electrical motor. But fossil fuels were cheaper, leading to the dominance of the combustible engine. This stalled the advancement in electrochemical technology. In this talk, Littlewood will discuss how to accelerate the transition to an electrically powered sustainable economy.
Building the Foundations of a Curious Student

The sun could be our ultimate renewable energy source but, as an energy source, suffers from its low intensity, and the massive collection areas required to meet the needs of powering the world’s growing economies. The sun is also intermittent, going down at night, which creates a need for energy storage on massive scales. Inspired by natural photosynthesis, a way to meet the energy storage challenge is by using the energy of the sun to produce “solar fuels” by “Artificial Photosynthesis” with energy stored in the chemical bonds of high energy molecules - hydrogen from water splitting or carbon-based fuels from reduction of CO2.
In this presentation, a hybrid approach to solar fuels is described. It is based on the integration of molecular assemblies for light absorption and catalysis with the band gap and surface properties of mesoscopic, nanoparticle films of inert metal oxides – TiO2, SnO2, NiO. In the resulting Dye Sensitized Photoelectrosynthesis Cells (DSPEC), light absorption by the chromophore and excited state injection into the conduction band of TiO2 initiates a series of electron transfer events. Transfer of the injected electron transfer to a cathode results in H2 evolution. With appropriate design features built in, including surface stabilization of the assembly and use of core/shell structured oxide films, relatively high per photon-absorbed efficiencies for visible light water splitting into hydrogen and oxygen has been achieved.

"The Protein Folding Problem"
127 Hayes-Healy Center — 4:15 p.m.
October 9, 2014
Protein folding can be understood as a biased search on a funneled but rugged energy landscape. The funneled nature of the protein energy landscape is a consequence of natural selection. Prof. Peter Wolynes of Rice University will discuss how this rather simple picture quantitatively predicts folding mechanism from native structure and sequence. He will also discuss recent advances using energy landscape ideas to create algorithms capable of predicting protein tertiary structure from sequence, protein binding sites and the nature of structurally specific protein misfolding relevant to disease. Finally, he will compare the physical folding energy landscape with the apparent fitness landscape of evolution as inferred from large genomic data sets.

The collective movement of cells in tissue is vital for normal development but also occurs in abnormal development, such as in cancer. We will review three models:
(i) A vertex-based model to describe cell motion in the early mouse embryo
(ii) A individual-based model forneural crest cell invasion
(iii) A model for acid-mediated tumor invasion
In each case we shall use the model to answer important issues concerning biology.
For example, in (i) we shall propose a role for rosette formation. In (ii) we propose that two cell types are necessary for successful invasion. Lastly, in (iii) we shall show how the model suggests possible therapeutic strategies for tumor control.

Single cell measurements reveal otherwise unobtainable information about how individual biological cells communicate with one another. This talk will focus on the use of single cell microelectrochemical measurements to study (1) blood platelets and (2) immune cell nanoparticle toxicity. Blood platelets are critical players in the process of hemostasis but, based on their small size and propensity to activate, real time single cell measurement of chemical messenger secretion has never been accomplished. Herein, microelectrochemical techniques reveal the concentration of chemical messengers stored in and the kinetics of chemical messenger release from individual platelets, including considerations of how extracellular and membrane manipulations influence platelet behavior. The same electrochemical techniques that reveal fundamental insight about blood platelets can also be used for applied studies of nanoparticle toxicity. In this case, carbon-fiber microelectrochemistry is used to probe critical cell function in immune system cells following exposure to engineered nanoparticles. The insight gained reveals how nanoparticles interact with cells as well as potential avenues to avoid this interaction in next generation nanoparticle-containing products.

Quantum theory, in particular the theory of entanglement, provides a coherent picture of the physical origin of randomness and the growth and decay of correlations, even in macroscopic systems exhibiting few traditional quantum hallmarks. It helps explain why the future is more uncertain than the past, and how correlations can become macroscopic and classical by being redundantly replicated throughout a system's environment. The most private information, exemplified by which path a particle takes through an interferometer, is not replicated, and exists only transiently: after the experiment is over no record remains anywhere in the universe of what ``happened''. At the other extreme is information that has been replicated and propagated so widely as to be infeasible to conceal and unlikely to be forgotten. Modern information technology has caused an explosion of such information, eroding privacy while making it harder for tyrants to rewrite the history of their misdeeds; and it is tempting to believe that all macroscopic information is permanent, making such cover-ups impossible in principle. But we argue, by comparing entropy flows into and out of the Earth with estimates of the planet's storage capacity, that most macroscopic classical information--for example the pattern of drops in last week's rainfall--is impermanent, eventually becoming nearly as ambiguous, from a terrestrial perspective, as the which-path information of an interferometer. Finally, we discuss prerequisites for a system to accumulate and maintain in its present state, as our world does, a complex and redundant record of at least some features of its past. Not all dynamics and initial conditions lead to this behavior, and in those that do, the behavior itself tends to be temporary, with the system losing its memory as it relaxes to thermal equilibrium.

To further our understanding of the complex network of molecular and cellular changes that impact disease risk, disease progression, severity, and drug response, multiple dimensions must be considered together. Schadt presents an approach for integrating a diversity of molecular and clinical data to uncover models that predict complex system behavior. By integrating diverse types of data on a large scale he demonstrates that some forms of common human diseases are most likely the result of perturbations to specific gene networks that in turn cause changes in the states of other gene networks both within and between tissues that drive biological processes associated with disease. His work has significant implications for drug discovery.

The underlying logic of our computers is of the 19th century. Computers might, instead, be designed to “think” in a quantum mechanical way. The tidal wave that brought us quantum mechanics may wash over us again 100 years later. There is reason to believe that quantum computing is the ultimate mode of information processing consistent with physics. So the short answer to, “What will quantum computers do?” is, “Everything possible.” Topology is geometry after you have forgotten local details; it deals with discrete structures. In physics local detail is usually of paramount importance. However one of the key physical ideas of the last 50 years – the “renormalization group” – tells us there are low temperature systems whose most important properties are topological in nature. The discrete nature of topology will allow us to control quantum mechanical evolutions in these systems with amazing precision. This is just what quantum computation requires.
