Atomic-scale simulations predict how to use nanoparticles to increase hydrogen production

Awesome!

What if industrial waste water could become fuel? With affordable, long-lasting catalysts, water could be split to produce hydrogen that could be used to power fuel cells or combustion engines.

By conducting complex simulations, scientists showed that adding lithium to aluminum nanoparticles results in orders-of-magnitude faster water-splitting reactions and higher hydrogen production rates compared to pure aluminum nanoparticles. The lithium allowed all the aluminum atoms to react, which increased yields (Nano Letters, “Hydrogen-on-demand using metallic alloy nanoparticles in water”).

For clarity, the water molecules were removed from the snapshot. Simulations were carried out at the Argonne Leadership Computing Facility.

Injectable Computers

With a radio specifically designed to communicate through tissue, Professors David Blaauw (http://web.eecs.umich.edu/faculty/blaauw/) and David Wentzloff (http://web.eecs.umich.edu/~wentzlof/) from the University of Michigan’s Electrical and Computer Engineering Department (https://www.eecs.umich.edu/ece/) are adding another level to a computer platform small enough to fit inside a medical grade syringe.

With this enabling technology, real time information can be applied to devices monitoring heart fibrillation as well as glucose monitoring for diabetics.

This new radio, designed by Graduate Student Research Assistant Yao Shi, can transmit information from inside the body up to one foot to a data base receiver, more than 5 times the distance from any known radio of equal size.

ABOUT THE PROFESSORS
David Blaauw received his B.S. from Duke University in 1986 and his Ph.D. from the University of Illinois, Urbana, in 1991. From 1993 until August 2001, he worked for Motorola, Inc. in Austin, TX, where he was the manager of the High Performance Design Technology group. Since August 2001, he has been on the faculty at the University of Michigan where he is currently a full Professor. His work has focused on VLSI design with particular emphasis on adaptive and low power design.

David D. Wentzloff received the B.S.E. degree in Electrical Engineering from the University of Michigan, Ann Arbor, in 1999, and the S.M. and Ph.D. degrees from the Massachusetts Institute of Technology, Cambridge, in 2002 and 2007, respectively. Since August, 2007 he has been with the University of Michigan, Ann Arbor, where he is currently an Associate Professor of Electrical Engineering and Computer Science. His research focuses on RF integrated circuits, with an emphasis on ultra-low power design.

Smart Dust Is Coming: New Camera Is the Size of a Grain of Salt

Miniaturization is one of the most world-shaking trends of the last several decades. Computer chips now have features measured in billionths of a meter. Sensors that once weighed kilograms fit inside your smartphone. But it doesn’t end there.

Researchers are aiming to take sensors smaller—much smaller.

In a new University of Stuttgart paper published in Nature Photonics, scientists describe tiny 3D printed lenses and show how they can take super sharp images. Each lens is 120 millionths of a meter in diameter—roughly the size of a grain of table salt—and because they’re 3D printed in one piece, complexity is no barrier. Any lens configuration that can be designed on a computer can be printed and used.

Research may lead to more durable electronic devices such as cellphones

Deep inside the electronic devices that proliferate in our world, from cell phones to solar cells, layer upon layer of almost unimaginably small transistors and delicate circuitry shuttle all-important electrons back and forth.

It is now possible to cram 6 million or more transistors into a single layer of these chips. Designers include layers of glassy between the electronics to insulate and protect these delicate components against the continual push and pull of heating and cooling that often causes them to fail.

A paper published today in the journal Nature Materials reshapes our understanding of the materials in those important protective layers. In the study, Stanford’s Reinhold Dauskardt, a professor of materials science and engineering, and doctoral candidate Joseph Burg reveal that those respond very differently to compression than they do to the tension of bending and stretching. The findings overturn conventional understanding and could have a lasting impact on the structure and reliability of the myriad devices that people depend upon every day.

DARPA approaches industry for new battlefield network algorithms and network protocols

Very nice.

ARLINGTON, Va., 27 June 2016. U.S. military researchers are asking industry for new algorithms and protocols for large, mission-aware, computer, communications, and battlefield network systems that physically are dispersed over large forward-deployed areas.

Officials of the U.S. Defense Advanced Research Projects Agency (DARPA) in Arlington, Va., issued a broad agency announcement on Friday (DARPA-BAA-16–41) for the Dispersed Computing project, which seeks to boost application and network performance of dispersed computing architectures by orders of magnitude with new algorithms and protocol stacks.

Examples of such architectures include network elements, radios, smart phones, or sensors with programmable execution environments; and portable micro-clouds of different form factors.

The future of storage may be in DNA

Definitely been seeing great research and success in Biocomputing; why I have been looking more and more in this area of the industry. Bio/ medical technology is our ultimate future state for singularity. It is the key that will help improve the enhancements we need to defeat cancer, aging, intelligence enhance, etc. as we have already seen the early hints already of what it can do for people, machines and data, the environment and resources. However, a word of caution, DNA ownership and security. We will need proper governance and oversight in this space.

Humanity uses a staggering amount of storage, and our needs are only expanding as we build data centers, better cameras, and all sorts of other data-heavy gizmos. It’s a problem scientists from companies like IBM, Intel, and Microsoft are trying to solve, and the solution might be in our DNA.

A recent Spectrum article takes a look at the quest to unlock the storage potential of human DNA. DNA molecules are the building blocks of life, piecing our genetic information into living forms. The theory is that we can convert digital files into biological material by translating it from binary code into genetic code. That’s right: the future of storage could be test tubes.

In April, representatives from IBM, Intel, Microsoft, and Twist Bioscience met with computer scientists and geneticists for a closed door session to discuss the issue. The event was cosponsored by the U.S. Intelligence Advanced Research Projects Activity (IARPA), who reportedly may be interested in helping fund a “DNA hard drive.”
