  • Technological Entrepreneurship – a Key to World Peace and Prosperity”
    cc MM CoCorrmickmick NorthwesternNorthwestern Engineering Engineering MaterialMaterialss ScienceScience and and EngineeringEngineering The 2014 McCormick Dean’s Seminar Series Dr. Dan Shechtman – Nobel Laureate Israel Institute of Technology Monday, October 20, 2014 4:00pm, McCormick Auditorium (Allen Center) Reception to follow north of McCormick Auditorium in the Allen Center “Technological Entrepreneurship – a Key to World Peace and Prosperity” Most of the countries in the world lack significant natural resources and are characterized by low standard of living with little hope for improvement due to population growth and mismanagement. This is true also for countries that are rich in natural resources, but do not use them wisely. People that live in countries that enjoy high standard of living are industrious and their countries industrial. The basic reason of this division is technological entrepreneurship nourished by free market economy. Technologically entrepreneurial people make the difference. So, is there hope for everybody on the globe to improve their lives? Can technological entrepreneurship be motivated and taught so that generations of determined entrepreneurs will build up thriving economies? The clear answer to both questions is yes, but the process will take time and dedication. It all starts with education in general and scientific- technical education in particular. There is also a way to expedite the process – start with the already educated engineers and scientists. These are the first candidates for entrepreneurial endeavors. They can do it, but need motivation, continuous instruction and encouraging economic environment until they create successful start-ups and serve as role models for others. The name of the game is motivation.

    2020 RESEARCH HIGHLIGHTS FROM THE SCHOOL OF CHEMICAL SCIENCES A word from the Head The year 2020 presented our School with multiple challenges, yet our teaching and research was able to continue in a sometimes revised form. We have seen research teams and spin-off companies pivot to COVID-19 – related research and development. All our researchers have adapted to working in new environments, including bubbles at Level 3 and decreased laboratory occupancies at Level 2. Staff and students have also maintained their overseas and domestic collaborations and many have found their home offices can be productive writing spaces. We decided that one way we could celebrate our resilience and The School has an international reputation in natural products productivity in research this year was to produce this report chemistry and medicinal peptide chemistry and also in the highlighting our successes.

    NATIONAL FOUNDATION FOR AMERICAN POLICY NFAP POLICY BRIEF» OCTOBER 2019 IMMIGRANTS AND NOBEL PRIZES : 1901- 2019 EXECUTIVE SUMMARY Immigrants have been awarded 38%, or 36 of 95, of the Nobel Prizes won by Americans in Chemistry, Medicine and Physics since 2000.1 In 2019, the U.S. winner of the Nobel Prize in Physics (James Peebles) and one of the two American winners of the Nobel Prize in Chemistry (M. Stanley Whittingham) were immigrants to the United States. This showing by immigrants in 2019 is consistent with recent history and illustrates the contributions of immigrants to America. In 2018, Gérard Mourou, an immigrant from France, won the Nobel Prize in Physics. In 2017, the sole American winner of the Nobel Prize in Chemistry was an immigrant, Joachim Frank, a Columbia University professor born in Germany. Immigrant Rainer Weiss, who was born in Germany and came to the United States as a teenager, was awarded the 2017 Nobel Prize in Physics, sharing it with two other Americans, Kip S. Thorne and Barry C. Barish. In 2016, all 6 American winners of the Nobel Prize in economics and scientific fields were immigrants.

    380 SEMICONDUCTING AND METALLIC POLYMERS: THE FOURTH GENERATION OF POLYMERIC MATERIALS Nobel Lecture, December 8, 2000 by ALAN J. HEEGER Department of Physics, Materials Department, Institute for Polymers and Organic Solids, University of California at Santa Barbara, Santa Barbara, CA 93106, USA. I. INTRODUCTION In 1976, Alan MacDiarmid, Hideki Shirakawa and I, together with a talented group of graduate students and post-doctoral researchers discovered con­ ducting polymers and the ability to dope these polymers over the full range from insulator to metal [1,2). This was particularly exciting because it created a new field of research on the boundary between chemistry and condensed matter physics, and because it created a number of opportunities: Conducting polymers opened the way to progress in understanding the fun­ damental chemistry and physics of n:-bonded macromolecules; Conducting polymers provided an opportunity to address questions which had been of fundamental interest to quantum chemistry for decades: Is there bond alternation in long chain polyenes? What is the relative importance of the electron-elecron and the electron­ lattice interactions in n:-bonded macromolecules? Conducting polymers provided an opportunity to address fundamental issues of importance to condensed matter physics as well, including, for example, the metal-insulator transition as envisioned by Neville Mott and Philip Anderson and the instability of one-dimensional metals discovered by Ru­ dolph Peierls ( the "Peierls Instability"). Finally - and perhaps most important - conducting polymers offered the promise of achieving a new generation of polymers: Materials which exhibit the electrical and optical properties of metals or semiconductors and which retain the attractive mechanical properties and processing advantages of polymers.
