It can be inconvenient to replace batteries in devices that need to work over long periods of time. But new technology being developed by MIT researchers could make such replacements unnecessary.

The world of R&D is full of collaboration. R&D Magazine has seen this directly through some of the winners of the R&D 100 awards in the past. However, not only is collaboration important to the world of R&D, but it is essentially important to all aspects of life. For the Army, it is not different.

Scientists at Arizona State Univ. have developed an elegant method for significantly improving the memory capacity of electronic chips. The researchers have shown that they can build stackable memory based on “ionic memory technology,” which could make them ideal candidates for storage cells in high-density memory. Best of all, the new method uses well-known electronics materials.

Derek Abbott, an Australian engineer, says that pure liquid or gas hydrogen is a much better energy solution than photovoltaics, or even hydrogen fuel cells. But isn’t it a little difficult to make? Not when paired with concentrated solar energy, he says, and the way to get it is very low-tech.

More than 200 plug-in hybrid electric vehicles are racking up the miles at Idaho National Lab in an effort to find the weak spots that rear their head during real-world evaluations. Results, which are being shared with industry and were produced by more than 75 testing partners, are now available online.

More than 300 people converged on Microsoft’s Redmond campus near Seattle to hear from more than 50 experts about innovative transportation strategies. Much of the discussion, of which co-sponsor Idaho National Lab was a major part, centered around solutions for the transportation infrastructure that will need be built in order to support new electric vehicles.

Driven by 550-W hydrogen fuel cell, the 37-pound aircraft
built by the Naval Research Laboratory has set an unofficial endurance record
for an aircraft of its kind. The invention of certain new technologies,
including lightweight hydrogen storage tanks, has allowed fuel cell systems to
provide seven times the energy per weight of batteries.

To increase the efficiency of PV cells that use organic dyes
as a solar collector (also called Grätzel cells), researchers in Spain are
attempting to improve the efficiency and reduce evaporation of the organic
components by incorporating ionic salts. The goal is to bring efficiency up
high enough to begin using these “greener” cells in devices such as cell
phones.

Batteries can power anything from small sensors to large systems. While scientists are finding ways to make them smaller but even more powerful, problems can arise when these batteries are much larger and heavier than the devices themselves. Univ. of Missouri researchers are developing a nuclear energy source that is smaller, lighter, and more efficient.

Special cellulose extracted from a certain species of green
algae can be formed into a conductive polymer, polypyrrole. Until now, the
material was considered too inefficient. Researchers have discovered, however,
that coating a substrate with a carefully tailored molecular-level layer of this
material yielded much higher storage and discharge rates, enough to build a
battery out of nonmetal parts.
