Advanced Energy Conversion and Storage Devices using Nanostructured Materials

One of the key challenges facing the widespread use and commercialization of promising energy devices (i.e. fuel cells, batteries, organic solar cells etc.) is the high cost of the electrocatalytic and electrolyte materials and inefficiencies in their assembly and utilization.  In this talk, I will present three examples of how we are designing nanomaterials such as graphene-based carbons and bulk metallic glass (BMG) alloys that can be incorporated into multifunctional composites for high performance nanostructured-enabled energy devices.
1) Spin Spray Layer-by-Layer (SSLBL) Assembly. We have developed a fully automated SSLBL system with deposition at sub-second cycle times allowing nano-level control over film growth and efficient formation of a conducting network not available with other solution based deposition methods for lithium ion battery electrodes. This platform technology can be used to create many other systems (i.e. specialty coatings, drug delivery, etc.)
2) Electrocatalysts. We will describe a new class of materials, Pt58Cu15Ni5P22 bulk metallic glass that can circumvent Pt-based anode poisoning and agglomeration/dissolution typically associated with supported catalysts during long-term operation in fuel cells. These amorphous metal alloys can serve as an interesting platform for next-generation catalysts and devices such as the first all bulk metallic glass micro fuel cell.
3) Network Electrodes (See Fig.). Here we describe a technique for developing freestanding multifunctional SWNT composite thin films that provides a fundamental engineering basis to bridge the gap between their nano and macroscale properties forsolar cell transparent conductive electrodes. We will also describe recent efforts in using these films as active layers in hybrid SWNT/Si solar cell device as well as the use of Förster resonance energy transfer for high efficiency small molecule and polymer solar cells.

Using Nanostructured Materials for Solar Energy Storage in Haiti

One of the key challenges facing the widespread use and commercialization of promising energy devices (i.e. fuel cells, batteries, organic solar cells etc.) is the high cost of the electrocatalytic and electrolyte materials and inefficiencies in their assembly and utilization. In this talk, I will present examples of how we are designing nanomaterials such as graphene-based carbons and bulk metallic glass (BMG) alloys that can be incorporated into multifunctional composites for high performance nanostructured-enabled energy devices.

One of our missions is to create devices and systems that will renewably improve our way of life. In this context, I will describe our new initiative to develop a solar powered computer lab in Haiti that can be used by school children during the day and can function as an Internet café afterschool. We are seeking partners to leverage resources at Yale University and MIT to make this project a reality for the summer of 2016. This project resonates with solar battery research taking place in our lab and gives us motivation to implement strategies of getting our research out of the lab and into product based systems.

Coco Fusco presents “Dangerous Moves: Performance and Politics in Cuba” as part of the MIT Women’s and Gender Studies Intellectual Forum.

Introduction by Ed Schiappa, John E. Burchard Professor of the Humanities and Head of the MIT Comparative Media Studies/Writing Program.

Thursday, March 12th  12 – 1:30 pm, The Chipman Room, 6-104

Lunch will be served, please RSVP to erneill@mit.edu and note dietary restrictions.

 

Dangerous Moves: Performance and Politics in Cuba is a study of the role of corporeal expressivity in development of social criticism in Cuban art. Fusco explores the work of performance artists from the 1980s to the present and examines how the Cuban state has wielded influence over performance through a combination of politics and practices that enable cultural production on the one hand and discipline public behavior on the other. The book will be published by Tate Publishing in the fall of 2015.

Kimani Toussaint presents at the first MIT MLK LUNCHEON SEMINAR of the Spring 2015 term.

Wednesday, February 18th  12 – 1:30 pm in the MIT Bush Room (10-105)

Refreshments will be served before the seminar.
Please contact Shauna Bush-Fenty at sfenty@mit.edu to RSVP.

 

Introduction to University of Illinois at Urbana-Champaign’s PROBE Lab: From Optical Nanoantennas to Second-Harmonic Generation Microscopy

The application of light to help solve problems in biology and nanotechnology has become increasingly popular because of the importance of these areas to society. This talk will highlight the major nano- and biophotonics projects pursued by the laboratory for Photonics Research of Bio/nano Environments (PROBE) at the University of Illinois at Urbana-Champaign. We will discuss our recent studies on optical nanoantennas.

In particular, we show how the optical parameter space, along with the nanoantenna geometric properties can be tuned for a range of applications, including light-driven particle manipulation. We will also highlight some of our work in biological imaging using second-harmonic generation (SHG) microscopy. In this case, we review the quantitative SHG microscopy techniques pursued by the PROBE lab for quantifying collagen fiber organization in biological tissues. The talk will conclude with a brief discussion of some of the future work pursued by the PROBE lab and is aimed at a general audience.

Understanding Security Threats in Modern Web Browsers

Web browsers are the user-facing gateway to important online services like email, video streaming, e-commerce, and social networking. Unfortunately, as web browsers become more complex, their threat surface increases, making the browser (and the pages that it displays) attractive targets for cyber-criminals. This talk will describe some specific threats to web security, and introduce several technologies that make it easier for developers to create safe web applications. These technologies preserve the rich interactive nature of modern web pages, while providing developers with better abstractions for reasoning about security.

Development of Multifunctional Plasmonic Nanoantenna Arrays

Plasmonic nanoantennas continue to be attractive for a variety of potential applications in nanotechnology, biology, and photonics due to their ability to tightly confine and strongly enhance optical fields. In recent years, the PROBE Lab at the University of Illinois at Urbana-Champaign has made significant developments in plasmonic nanoantenna technology by more closely exploring the rich parameter space associated with these structures. This talk will discuss our work with arrays of Au bowtie nanoantennas (BNAs) with an emphasis on harnessing their field enhancement properties for improved transport and manipulation of microparticles. In addition, recent efforts to introduce the mechanical degree-of-freedom by placing the BNAs on silicon dioxide pillars will also be discussed. Aside from the particle manipulation features that these pillar-supported BNAs (pBNAs) share with their substrate-bound counterparts, the use of pBNAs to record the optical near field will also be presented. The talk will conclude with a brief discussion on some of the future work pursued by the PROBE lab, including adapting BNAs for lab-on-achip applications and nanoscale acoustic generation.
