Donna Strickland '89 (Phd), a Self-Described “Laser Jock,” Receives
Donna Strickland ’89 (PhD), a self-described “laser jock,” receives the Nobel Prize, along with her advisor, Gérard Mourou, for work they did at the Laboratory for Laser Energetics. By Lindsey Valich Donna Strickland ’89 (PhD) still recalls the visit she took to the On- tario Science Centre when she was a child growing up in the town of Guelph, outside Toronto. Her father pointed to a laser display. “ ‘Donna, this is the way of the future,’ ” Strickland remembers him telling her. Lloyd Strickland, an electrical engineer, along with Donna’s moth- er, sister, and brother, was part of the family that “continually sup- ported and encouraged me through all my years of education,” Donna Strickland wrote in the acknowledgments of her PhD thesis, “De- velopment of an Ultra-Bright Laser and an Application to Multi- Photon Ionization.” She was captivated by that laser display. And since then, she says, “I’ve always thought lasers were cool.” Her passion for laser science research and her commitment to be- ing a “laser jock,” as she has called herself, has led her across North America, from Canada to the United States and back again. But it’s the work that she did as a graduate student at Rochester in the 1980s that has earned her the remarkable accolade of Nobel Prize laureate. When Strickland entered the University’s graduate program in op- tics, laser physicists were grappling with a thorny problem: how could they create ultrashort, high-intensity laser pulses that wouldn’t de- stroy the very material the laser was used to explore in the first place? Working with former Rochester engineering professor Gérard Mourou, Strickland developed and made workable a method to over- come the barrier. -

Chirped Pulse Amplification, CPA, Was Both Simple and Elegant
THE NOBEL PRIZE IN PHYSICS 2018 POPULAR SCIENCE BACKGROUND Tools made of light The inventions being honoured this year have revolutionised laser physics. Extremely small objects and incredibly fast processes now appear in a new light. Not only physics, but also chemistry, biology and medicine have gained precision instruments for use in basic research and practical applications. Arthur Ashkin invented optical tweezers that grab particles, atoms and molecules with their laser beam fingers. Viruses, bacteria and other living cells can be held too, and examined and manipulated without being damaged. Ashkin’s optical tweezers have created entirely new opportunities for observing and controlling the machinery of life. Gérard Mourou and Donna Strickland paved the way towards the shortest and most intense laser pulses created by mankind. The technique they developed has opened up new areas of research and led to broad industrial and medical applications; for example, millions of eye operations are performed every year with the sharpest of laser beams. Travelling in beams of light Arthur Ashkin had a dream: imagine if beams of light could be put to work and made to move objects. In the cult series that started in the mid-1960s, Star Trek, a tractor beam can be used to retrieve objects, even asteroids in space, without touching them. Of course, this sounds like pure science fic- tion. We can feel that sunbeams carry energy – we get hot in the sun – although the pressure from the beam is too small for us to feel even a tiny prod. But could its force be enough to push extremely tiny particles and atoms? Immediately after the invention of the first laser in 1960, Ashkin began to experiment with the new instrument at Bell Laboratories outside New York. -

Nfap Policy Brief » October 2019
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.

The Federal Government: a Nobel Profession
The Federal Government: A Nobel Profession A Report on Pathbreaking Nobel Laureates in Government 1901 - 2002 INTRODUCTION The Nobel Prize is synonymous with greatness. A list of Nobel Prize winners offers a quick register of the world’s best and brightest, whose accomplishments in literature, economics, medicine, science and peace have enriched the lives of millions. Over the past century, 270 Americans have received the Nobel Prize for innovation and ingenuity. Approximately one-fourth of these distinguished individuals are, or were, federal employees. Their Nobel contributions have resulted in the eradication of polio, the mapping of the human genome, the harnessing of atomic energy, the achievement of peace between nations, and advances in medicine that not only prolong our lives, but “This report should serve improve their quality. as an inspiration and a During Public Employees Recognition Week (May 4-10, 2003), in an effort to recognize and honor the reminder to us all of the ideas and accomplishments of federal workers past and present, the Partnership for Public Service offers innovation and nobility of this report highlighting 50 American Nobel laureates the work civil servants do whose award-winning achievements occurred while they served in government or whose public service every day and its far- work had an impact on their career achievements.

Also included are five Americans whose work merited the Peace Prize. Despite this legacy of accomplishment, too few Americans see the federal government as an incubator for innovation and discovery. -

Rock Thermochemistry Laboratory and NEAT ORU, University of California at Davis, Davis, CA 95616, USA 2 School of Engineering, Brown University, Providence, RI 02912, USA * Correspondence: [email protected] (S.V.U.); [email protected] (A.N.); [email protected] (Q.-J.H.); [email protected] (A.v.d.W.) Received: 6 August 2019; Accepted: 22 August 2019; Published: 26 August 2019 Abstract: Among transition metal carbides and nitrides, zirconium, and hafnium compounds are the most stable and have the highest melting temperatures. Here we review published data on phases and phase equilibria in Hf-Zr-C-N-O system, from experiment and ab initio computations with focus on rocksalt Zr and Hf carbides and nitrides, their solid solutions and oxygen solubility limits. The systematic experimental studies on phase equilibria and thermodynamics were performed mainly 40–60 years ago, mostly for binary systems of Zr and Hf with C and N. Since then, synthesis of several oxynitrides was reported in the fluorite-derivative type of structures, of orthorhombic and cubic higher nitrides Zr3N4 and Hf3N4. An ever-increasing stream of data is provided by ab initio computations, and one of the testable predictions is that the rocksalt HfC0.75N0.22 phase would have the highest known melting temperature. Experimental data on melting temperatures of hafnium carbonitrides are absent, but minimum in heat capacity and maximum in hardness were reported for Hf(C,N) solid solutions. -
