In continuous operation since its beginning in 1987, more than 10,000 crystals have been grown in the Molecular Beam Epitaxy (MBE) lab of Professor Jacek Furdyna. Materials designed and fabricated in the MBE lab led to collaborations with scientists in more than 100 institutions outside of Notre Dame, including some 35 in foreign countries, resulting in significant worldwide visibility.
Notre Dame's Center for Nano Science and Technology
NDnano is a world-class, collaborative research center that includes faculty from seven departments across the colleges of Engineering and Science. The Center is focused on developing, characterizing, and applying new nanotechnology-based materials, processes, devices, and solutions that will better society.
NDnano’s mission is to promote, enable, and advance multidisciplinary nanotechnology education and research to include:
- defining, manipulating, and controlling the properties of new nano-materials
- collaborating with peer universities, industry, and government to accelerate advances in the field of nano science
- developing solutions and applications that help address society's global issues while representing a force for good in the discussion on the ethics and possible societal impacts of the new science
From the earliest of days, researchers have been recording their observations, analyzing what they see to interpret and apply the facts before them. Today, however, imaging especially in biomedical communities requires more than the human eye or even incredibly accurate “cameras.” In cases such as the joint project between Notre Dame and Pennsylvania State University, it requires close collaboration between biologists and computer scientists using deep-learning methods for artificial intelligence to speed up and improve the process.
Kenneth T. Christensen, professor and collegiate chair in fluid mechanics and chair of the Department of Aerospace and Mechanical Engineering, and Umesh Garg, professor of experimental nuclear physics have been named fellows.
Title: Operando Spectroscopy in Catalysis, Membranes, and Beyond
Dr. Casey O’Brien, Assistant Professor
Department of Chemical and Biomolecular Engineering
Operando spectroscopy is the methodology in which the structure of a catalytic material is analyzed spectroscopically while the reaction products are measured simultaneously. By characterizing the catalyst structure and analyzing the reaction products simultaneously, it is possible to elucidate reaction mechanisms and to identify catalyst structure-function relationships. In effect, operando spectroscopy enables a more rational design of catalytic materials than is possible with ex-situ spectroscopic techniques. While this methodology has been applied almost exclusively to the study of catalytic materials, other research areas would benefit greatly by adopting the operando tools and techniques. In this presentation, I will first demonstrate the utility of operando spectroscopy in elucidating catalytic reaction mechanisms. Then I will discuss how the operando methodology can be applied to understand transport mechanisms in gas separation membranes. Finally, I will discuss other areas that could benefit from the operando spectroscopy methodology. …

Modern logic and memory FETs consist of a dual (or triple) layer gate insulator stack. Charging of defects (pre-existing and generated during operation) in the gate stack shifts the performance of the FETs and is responsible for the eventual reliability of these devices and associated systems. In this talk, we will discuss several mechanisms and models that have been proposed in the literature to model the time kinetics of these defects, and benchmark those against experimental data. Examples will be shown using Bias Temperature Instability in logic FETs, and modifications (if any) needed to apply these models for memory devices will be discussed. …
The University of Notre Dame has opened its annual competition for the Naughton Fellowships. The prestigious international fellowships provide funding for exceptional Ph.D., masters, or undergraduate students with an aptitude for the STEM disciplines to complete research or study in Ireland or at Notre Dame.…
