Watching Nanoscale Fluids Flow,
California Institute of Technology, Pasadena CA, June 26, 2014.
At the nanoscale, where objects are measured in billionths of meters and events transpire in trillionths of seconds, things do not always behave as our experiences with the macro-world might lead us to expect. Water, for example, seems to flow much faster within carbon nanotubes than classical physics says should be possible. Now imagine trying to capture movies of these almost imperceptibly small nanoscale movements...
FEI Introduces the New Tecnai Femto Ultrafast Electron Microscope,
FEI, Hillsboro OR, October 29, 2013.
FEI (Nasdaq:FEIC) today released the TecnaiTM Femto ultrafast electron microscope (UEM), enabling scientists to explore ultrafast events and processes that occur at the atomic and molecular spatial scale over time spans measured in femtoseconds (10-15 seconds). These include such fundamental processes as the absorption of light energy and its transformation into heat or mechanical changes (photoactuation) and the crystallization or recrystallization of materials &mdash including large biological molecules for structural analysis. The Tecnai Femto is the first system to commercialize the patented ultrafast electron microscopy technology pioneered by Nobel laureate Prof. Ahmed Zewail at the California Institute of Technology. The first Tecnai Femto UEM will be installed at the University of Minnesota in November 2013...
Caltech Nobelist Zewail Named to UN Scientific Advisory Board,
California Institute of Technology, Pasadena CA, October 21, 2013.
Ahmed Zewail, Linus Pauling Professor of Chemistry and professor of physics, has been selected as one of 26 members of a new Scientific Advisory Board established by the United Nations secretary-general.
The board, which will meet twice per year, will provide advice on science, technology, and innovation concerning sustainable development to the secretary-general and the heads of UN organizations. The creation of this new board, which was formally announced September 24 at the UN's first High-Level Political Forum on Sustainable Development, was the result of a recommendation from the report of the High-Level Panel on Global Sustainability in January 2012...
Visualizing Biological Networks in 4D,
California Institute of Technology, Pasadena CA, February 8, 2013.
Every great structure, from the Empire State Building to the Golden Gate Bridge, depends on specific mechanical properties to remain strong and reliable. Rigidity &mdash a material's stiffness &mdash is of particular importance for maintaining the robust functionality of everything from colossal edifices to the tiniest of nanoscale structures. In biological nanostructures, like DNA networks, it has been difficult to measure this stiffness, which is essential to their properties and functions. But scientists at the California Institute of Technology (Caltech) have recently developed techniques for visualizing the behavior of biological nanostructures in both space and time, allowing them to directly measure stiffness and map its variation throughout the network...

the world's largest scientific society.
The award will be presented at a banquet ceremony in the Anaheim Marriott Hotel during the ACS' 241st
National Meeting and Exposition. More than 13,000 scientists and others are expected for the week-long
event, which includes 9,500 reports on new advances in science, and
is one of the largest scientific conferences of the year....

Caltech Scientists Film Photons with Electrons,
California Institute of Technology, Pasadena CA, December 16, 2009.
Techniques recently invented by researchers at the California Institute of Technology (Caltech) which allow the real-time, real-space visualization of fleeting changes in the structure of nanoscale matter have been used to image the evanescent electrical fields produced by the interaction of electrons and photons, and to track changes in atomic-scale structures.
Papers describing the novel technologies appear in the December 17 issue of Nature and the October 30 issue of Science.
Four-dimensional (4D) microscopy — the methodology upon which the new techniques were based — was developed at Caltech's Physical Biology Center for Ultrafast Science and Technology...
Nobel Laureate Ahmed Zewail Named United States Science Envoy,
California Institute of Technology, Pasadena CA, November 13, 2009.
Nobel Laureate Ahmed Zewail, the Linus Pauling Professor of Chemistry and professor of physics at the California Institute of Technology (Caltech), has been named an envoy in the new U.S. Science Envoy Program, created to foster science and technology collaborations between the United States and nations throughout the Middle East, North Africa, and South and Southeast Asia. Zewail, who was also appointed to President Obama's Council of Advisors on Science and Technology earlier this year, is one of three eminent Americans who will serve as the first scientist-diplomats in the new program...
President Obama names Ahmed Zewail of Caltech to Science and Tech Council,
California Institute of Technology, Pasadena CA, April 27, 2009.
President Barack Obama named Nobel laureate Ahmed Zewail of Caltech to the President's Council of Advisors on Science and Technology.
Zewail, 63, of San Marino, is the Linus Pauling Professor of Chemistry and a physics professor at Caltech. He was awarded the Nobel Prize in Chemistry in 1999 for his pioneering work in femtoscience, which makes it possible to observe atoms in motion.
Zewail will maintain his current duties at Caltech, according to the school. His new responsibilities involve joining scientists, educators and other experts in meeting with Obama every other month. The council is tasked with advising the president on matters of education, energy, health, climate change, environment, security and the economy...
Caltech 4D Microscope Revolutionizes the Way We Look at the Nano World,
California Institute of Technology, Pasadena CA, November 20, 2008.
More than a century ago, the development of the earliest motion picture technology made what had been previously thought "magical" a reality: capturing and recreating the movement and dynamism of the world around us. A breakthrough technology based on new concepts has now accomplished a similar feat, but on an atomic scale—by allowing, for the first time, the real-time, real-space visualization of fleeting changes in the structure and shape of matter barely a billionth of a meter in size.
Such "movies" of atomic changes in materials of gold and graphite, obtained using the technique, are featured in a paper appearing in the November 21 issue of the journal Science. 4D microscopy videos can be viewed at the UST web site...
