Optoelectronics origami: An easy-to-make, double-duty curved image sensor

In a breakthrough that could, for example, lead to cameras with beyond-the-state-of-the-art features such as infinite depth of field, wider view angle, low aberrations, and vastly increased pixel density, flexible optoelectronics pioneer Zhenqiang (Jack) Ma has devised a method for making curved digital image sensors in shapes that mimic an insect’s compound eye (convex) and a mammal’s “pin-hole” eye (concave).

Scientists capture colliding organic nanoparticles on video for first time

A Northwestern University research team is the first to capture on video organic nanoparticles colliding and fusing together. This unprecedented view of “chemistry in motion” will aid Northwestern nanoscientists developing new drug delivery methods as well as demonstrate to researchers around the globe how an emerging imaging technique opens a new window on a very tiny world. https://news.northwestern.edu/stories/2017/november/scientists-capture-colliding-organic-nanoparticles-on-video-for-first-time/


Math gets real in strong, lightweight structures

Rice University engineers are using 3-D printers to turn structures that have until now existed primarily in theory into strong, light and durable materials with complex, repeating patterns. The porous structures called schwarzites are designed with computer algorithms, but Rice researchers found they could send data from the programs to printers and make macroscale, polymer models for testing. Their samples strive to use as little material as possible and still provide strength and compressibility. http://news.rice.edu/2017/11/16/math-gets-real-in-strong-lightweight-structures/

The relentless pursuit of hypersonic flight

How much new science will it take to design a vehicle that can routinely fly at many times the speed of sound? http://physicstoday.scitation.org/doi/10.1063/PT.3.3762

A strange new world of light

Now, researchers at the Harvard John A. Paulson School of Engineering and Applied Sciences have developed a tool to generate new, more complex states of light in a completely different way. The research is published in Science. https://www.seas.harvard.edu/news/2017/11/strange-new-world-of-light

Old phones get new life in high-powered computer servers

In a recent paper, graduate student Mohammad Shahrad and David Wentzlaff, an assistant professor of electrical engineering, demonstrated that it is possible to build servers out of ranks of old smartphones. Servers are specialized computers that provide data, storage or computing power to other computers. They are at the heart of the internet, from social media or video streaming to high-security banking. https://www.princeton.edu/news/2017/10/24/old-phones-get-new-life-high-powered-computer-servers


Thruster for Mars mission breaks records

An advanced space engine in the running to propel humans to Mars has broken the records for operating current, power and thrust for a device of its kind, known as a Hall thruster. The development of the thruster was led by Alec Gallimore, University of Michigan professor of aerospace engineering and the Robert J. Vlasic Dean of Engineering. http://ns.umich.edu/new/releases/25192-thruster-for-mars-mission-breaks-records

CPS verification expert wins Air Force young investigator research award

Taylor T. Johnson, an assistant professor of computer science, computer engineering, and electrical engineering, has been recognized with an early career award from the Air Force Office of Scientific Research. He will receive a three-year grant to work on formal verification for cyber-physical systems (CPS) that is understandable and reusable.

Chad Mirkin receives 2017 Wilhelm Exner Medal in Austria

Northwestern University’s Chad A. Mirkin received a prestigious 2017 Wilhelm Exner Medal at an award ceremony at the Hofburg Palace in Vienna on Oct. 19. He and CERN Director-General and particle physicist Fabiola Gianotti were each recognized with a medal at the ceremony. https://news.northwestern.edu/stories/2017/october/chad-mirkin-receives-2017-wilhelm-exner-medal-in-austria/

Miniature water droplets could solve an origin-of-life riddle, Stanford researchers find

It is one of the great ironies of biochemistry: life on Earth could not have begun without water; yet water stymies some chemical reactions necessary for life itself. Now, researchers report today in Proceedings of the National Academy of Sciences, they have found a novel, even poetic solution to the so-called “water problem” in the form of miniature droplets of water, formed perhaps in the mist of a crashing ocean wave or the clouds in the sky. https://news.stanford.edu/2017/10/20/miniature-droplets-solve-origin-life-riddle/


Astronomers announce the first observation of the collision of neutron stars and birth of a Blue Kilonova



AFRL, Harvard researchers invent new method of hybrid 3-D printing for flexible electronics

A collaboration between scientists at the Air Force Research Laboratory and the Wyss Institute for Biologically Inspired Engineering at Harvard University has resulted in a new method for digital design and printing of stretchable, flexible electronics. The process, called Hybrid 3-D printing, uses additive manufacturing to integrate soft, conductive inks with a material substrate to create stretchable, wearable electronic devices. http://www.wpafb.af.mil/News/Article-Display/Article/1345097/afrl-harvard-researchers-invent-new-method-of-hybrid-3-d-printing-for-flexible/

Long nanotubes make strong fibers

The Rice lab of chemist and chemical engineer Matteo Pasquali, which demonstrated its pioneering method to spin carbon nanotube into fibers in 2013, has advanced the art of making nanotube-based materials with two new papers in the American Chemical Society’s ACS Applied Materials and Interfaces. https://engineering.rice.edu/long_nantubes

Vibrating nanoparticles interact

Like a tuning fork struck with a mallet, tiny gold nanodisks can be made to vibrate at resonant frequencies when struck by light. In new research, Rice University researchers showed they can selectively alter those vibrational frequencies by gathering different-sized nanodisks into groups. https://engineering.rice.edu/vibrating_nanoparticles
