Powin Energy, a company focused on creating dynamic energy storage solutions, recently announced their plan to install a 30 kW/40 kW-hour battery system at the University of Washington’s Washington Clean Energy Testbeds. The testbed facility was developed by UW to scale-up, prototype, test, and validate new clean energy solutions. Powin Energy hopes to assist the researchers at the facility in their quest to develop clean energy innovation.

“We’re excited about this installation at the University of Washington because it will give our technology a more rigorous workout than most real-world installations that don’t approach the far ends of usage parameters,” Virgil Beaston, CTO of Powin Energy, said in a statement.

Venkat Subramanian, technical editor of the Journal of The Electrochemical Society and UW professor, discussed this energy storage opportunity, stating the he and his team could “use the Powin BESS to measure the performance of energy devices and algorithms when integrated into real and simulated system environments.”

Powin’s partnership with UW comes after the company’s development of its newly patented Battery Pack Operating system, which was designed to make its way into the utility-scale storage market. The company has already installed a 2MW/8MW-hour battery system in Irvine, CA.

At its most recent board of directors meeting during PRiME 2016, ECS leadership approved the addition of students who are ECS members as voting members of the Individual Membership Committee and Education Committee. This governance change is many years in the making with the understanding that if the student member voice is most warranted, it is within these two committees. The timing is perfect as ECS student membership is burgeoning with 64 student chapters around the world and more to come. Our student population takes full advantage of our biannual meetings to network, share, and learn so volunteer leadership within our governance structure is an appropriate next step.

About the Committees

The Individual Membership Committee is charged with retaining and recruiting our organization’s membership on a Society, student and institutional level. The Education Committee has the responsibility of providing educational and career development opportunities to that group. The scope of the work of the two committees are broad with the potential for further growth that parallels the growth of our constituency, its needs and external forces such as new technology and shifts in best practices.

Researchers from the University of California, Riverside recently combined photosynthesis and physics to make a key discovery that could lead to highly efficient solar cells.

Nathan Gabor, a physicist, began exploring photosynthesis when he asked himself a fundamental question in 2010: Why are plants green? This question probed him to combine his physics training with biology.
Over the past six years, Gabor has been rethinking energy conversion in light of these questions. His goal was to make solar cells that more efficiently absorb intermittent energy from the sun and increase past the current 20 percent efficiency. In this, he was inspired by the plants that had evolved over time to do exactly what he hoped solar cells would be able to do.

This from University of California, Riverside:

[The scientists] addressed the problem by designing a new type of quantum heat engine photocell, which helps manipulate the flow of energy in solar cells. The design incorporates a heat engine photocell that absorbs photons from the sun and converts the photon energy into electricity.

Surprisingly, the researchers found that the quantum heat engine photocell could regulate solar power conversion without requiring active feedback or adaptive control mechanisms. In conventional photovoltaic technology, which is used on rooftops and solar farms today, fluctuations in solar power must be suppressed by voltage converters and feedback controllers, which dramatically reduce the overall efficiency.

At the core of the research, Gabor and his team are looking to connect quantum mechanical structure to the greenest plants.

For the past four decades, the electronics industry has been driven by what is called “Moore’s Law,” which is not a law but more an axiom or observation. Effectively, it suggests that the electronic devices double in speed and capability about every two years. And indeed, every year tech companies come up with new, faster, smarter and better gadgets.

Specifically, Moore’s Law, as articulated by Intel cofounder Gordon Moore, is that “The number of transistors incorporated in a chip will approximately double every 24 months.” Transistors, tiny electrical switches, are the fundamental unit that drives all the electronic gadgets we can think of. As they get smaller, they also get faster and consume less electricity to operate.

In the technology world, one of the biggest questions of the 21st century is: How small can we make transistors? If there is a limit to how tiny they can get, we might reach a point at which we can no longer continue to make smaller, more powerful, more efficient devices. It’s an industry with more than US$200 billion in annual revenue in the U.S. alone. Might it stop growing?

Getting close to the limit

At the present, companies like Intel are mass-producing transistors 14 nanometers across – just 14 times wider than DNA molecules. They’re made of silicon, the second-most abundant material on our planet. Silicon’s atomic size is about 0.2 nanometers.

Today’s transistors are about 70 silicon atoms wide, so the possibility of making them even smaller is itself shrinking. We’re getting very close to the limit of how small we can make a transistor.

By using mild electric current, a team of researchers from Washington State University has demonstrated the ability to beat drug-resistant bacterial infections – a technology with the potential to treat chronic wound infections.

Lead by ECS member Haluk Beyenal, the team combined an antibiotic with electrical current to kill the highly persistent Pseudomonas aeruginosa PAO1 bacteria. That very same bacteria can seen in infections of the lung, cystic fibrosis, and even chronic wounds.

“I didn’t believe it. Killing most of the persister cells was unexpected,” Beyenal says. “Then we replicated it many, many times.”

The 21st century has brought new light to strains of antibiotic-resistant bacteria. In many cases, this bacterial resistance is caused by the widespread use of antibiotics in the 20th century. According to the Centers for Disease Control, at least 23,000 deaths per year are attributed to antibiotic-resistant bacterial infections.

Two female tech pioneers won the Presidential Medal of Freedom. Grace Hopper, known as the “first lady of software,” and Margaret Hamilton, regarded for her leadership role in a NASA software team that helped land a man on the moon, continued to break the glass ceilings in computer science upon receiving this prestigious award.

Hopper was one of the first programmers of the Harvard Mark I and a pioneer in computer science until she passed away in 1992.

When discussing Hopper’s achievements, U.S. President Barack Obama said, “If Wright is flight, and Edison is light, then Hopper is code.”

Hamilton played a major role on the 1960s NASA team that got a man to the moon. She was critical in developing the on-board flight software for the Apollo space program.

President Obama said, “Luckily for us, Margaret never stopped pioneering. She symbolizes that generation of unsung women who helped send humankind into space.”

From cellphones to cyber command, the work of these women has helped shape the world we currently live in.

According to scientists at the University at Buffalo, a new glowing dye called BODIPY could be a central part of the liquid-based batteries that researchers are looking at to power our cars and homes.

BODIPY – or boron-dipyrromethene – is a fluorescent material that researchers believe could be an ideal material for stockpiling energy.

While the dye is fluorescent, that’s not what initially attracted scientists. According to new research, the dye has chemical properties that enables it to store electrons and participate in electron transfer. These two properties are critical for energy storage.

The new research shows that BODIPY-based batteries operate efficiently and display promising potential for longevity, functioning for more than 100 charge cycles.

“As the world becomes more reliant on alternative energy sources, one of the huge questions we have is, ‘How do we store energy?’ What happens when the sun goes down at night, or when the wind stops?” says lead researcher Timothy Cook, ECS member and assistant professor of chemistry at the University at Buffalo. “All these energy sources are intermittent, so we need batteries that can store enough energy to power the average house.”

Newly developed semiconductor materials are showing promising potential for the future of super-fast electronics.

A new study out of the University of Manchester details a new material called Indium Selenide (InSe). Like graphene, InSe if just a few atoms thick, but it differs from the “wonder material” in a few critical ways. While graphene has been hailed for its electronic properties, researchers state that it does not have an energy gap – making graphene behave more like a metal than a semiconductor.

Similarly, InSe can be nearly as thin as graphene while exhibiting electronic properties higher than that of silicon. Most importantly, InSe has a large energy gap, which could open the door to super-fast, next-gen electronic devices.
