To produce a cost-effective redox flow battery, researchers based at the South China University of Technology have synthesized a molecular compound that serves as a low-cost electrolyte, enabling a stable flow battery that retains 99.98% capacity per cycle. They published their approach on August 14 in the Energy Material Advances.

Comprising two tanks of opposing liquid electrolytes, the battery pumps the positive and negative liquids along a membrane separator sandwiched between electrodes, facilitating ion exchanges to produce energy. Significant work has been dedicated to developing the negative electrolyte liquid, while the positive electrolyte liquid has received less attention, according to corresponding author Zhenxing Liang, professor in the Key Laboratory of Fuel Cell Technology of Guangdong Province, School of Chemistry and Chemical Engineering, South China University of Technology.

“Aqueous redox flow batteries can realize the stable electrical output for using unsteady solar and wind energy, and they have been recognized as a promising large-scale energy storage ,” Liang said. “Electroactive organic merit of element abundance, low cost and flexible molecular control over the electrochemical features for both positive and negative electrolytes are regarded as key to developing next-generation redox flow batteries.”

A team of researchers led by an Institute for Quantum Computing (IQC) faculty member performed the first-ever simulation of baryons—fundamental quantum particles—on a quantum computer.

With their results, the team has taken a step towards more complex quantum simulations that will allow scientists to study neutron stars, learn more about the earliest moments of the universe, and realize the revolutionary potential of quantum computers.

“This is an important step forward—it is the first of baryons on a quantum ever,” Christine Muschik, an IQC faculty member, said. “Instead of smashing particles in an accelerator, a quantum computer may one day allow us to simulate these interactions that we use to study the origins of the universe and so much more.”

The revolution will be electrified.

For decades, gas-engine power equipment was the only choice for yardwork, followed by corded power tools at a distant second. Anything powered by a battery was either ineffective or an expensive novelty. The few successful versions of battery-powered outdoor equipment were limited to low-power applications, like grass shears. Of course, for every rule there’s an exception: We reported on the highly effective GE Elec-Trak battery-powered tractor and Black & Decker’s somewhat effective battery mowers in our April 1970 issue.

In many respects, gas-engine equipment still rules the outdoors in terms of power and cost effectiveness–at least for people with serious work to do. But a revolution in outdoor power is occurring. For many people doing yardwork, cordless power tools are now the default choice. This has stood the status quo on its head.

Forget all the nanotechnology devoted to fighting cancer, and just consider that nanoparticles have invaded makeup, anti-odor socks, sunscreen, plastic beer bottles and home pregnancy tests. Now scientists have developed a way to assess the health and environmental impact of such nanoparticles: a tiny microresonator that can detect and measure individual particles smaller than a single virus.

The microresonator is a lab-on-a-chip that harnesses the “whispering gallery” concept that’s displayed by buildings such as St. Paul’s Cathedral in London. The cathedral’s domed gallery can carry whispers easily across to the other side, but normal-volume voices end up garbled after bouncing around the dome multiple times.

Similarly, microresonators can bounce laser light many times around a circular “waveguide,” such as a glass ring. A laser frequency must perfectly fit the circumference of a ring to achieve this whispering-gallery mode.

Asia-Pacific has become the most important region in the world. A region in which the United States and China are fighting a battle for political and military dominance. As we told you in a past video, the distance separating these two powers is still worlds apart, yet China is committed to becoming a regional mega-power.

To achieve this, the People’s Liberation Army is developing a whole new series of weapons with which they aspire to gain control of Asia Pacific. In this video we give you some clues about the weapons programs with which China wants to pursue its goal.

Green energy company Fortescue Future Industries (FFI) is collaborating with MMA Offshore to convert a 75-meter (246-feet) vessel, the “MMA Leveque”, so that it can run almost entirely on green ammonia by 2022, a press statement from FFI explains.

In the same statement, the company reveals that its chairman, billionaire Andrew Forrest, called for an industry-wide push for shipping to reach net-zero by 2040 during a keynote for ‘Transport Day’ at the COP26 conference in Glasgow this week, a United Nations summit aimed at accelerating action on climate change.

The MMA Leveque is one of several Fortescue Metal Group’s vessels and vehicles that will be transformed to operate on green fuels, as the company also says it is gradually working on converting its fleet of trucks, locomotives, and ships. Earlier this year, FFI successfully demonstrated the combustion of a blended ammonia fuel in a locomotive, and it says it will soon be able to power trains on one hundred percent green ammonia.

Virtual and augmented reality headsets are designed to place wearers directly into other environments, worlds, and experiences. While the technology is already popular among consumers for its immersive quality, there could be a future where the holographic displays look even more like real life. In their own pursuit of these better displays, the Stanford Computational Imaging Lab has combined their expertise in optics and artificial intelligence. Their most recent advances in this area are detailed in a paper published today (November 12, 2021) in Science Advances and work that will be presented at SIGGRAPH ASIA 2021 in December.

At its core, this research confronts the fact that current augmented and virtual reality displays only show 2D images to each of the viewer’s eyes, instead of 3D – or holographic – images like we see in the real world.

“They are not perceptually realistic,” explained Gordon Wetzstein, associate professor of electrical engineering and leader of the Stanford Computational Imaging Lab. Wetzstein and his colleagues are working to come up with solutions to bridge this gap between simulation and reality while creating displays that are more visually appealing and easier on the eyes.

In the race toward practical fusion energy, tokamaks (donut-shaped plasma devices) are the leading concept—they have achieved better confinement and higher plasma temperatures than any other configuration. Two major magnetic fields are used to contain the plasma: a toroidal field (along the axes of the donut) produced by external coils and the field from a ring current flowing in the plasma itself. The performance of a tokamak, however, comes with an Achilles heel—the possibility of disruptions, a sudden termination of the plasma driven by instabilities in the plasma current. Since the plasma current provides the equilibrium and confinement for the tokamak, the challenge of taming disruptions must be addressed and solved.

As the magnitudes of the plasma current and plasma energy increase, disruptions can cause more damage. As such, they are a particularly important concern for the newest and most powerful machines, such as the SPARC . SPARC is a compact, high-magnetic– tokamak under design and in the early stages of construction by a joint team from the Massachusetts Institute of Technology and Commonwealth Fusion Systems. The SPARC plasma is predicted to produce more than 10 times the power than is required to maintain its 250 million F temperatures. All tokamaks of this performance class must develop strategies to protect the machine against disruptions.

A solution, however, may be in hand. Prompted by a theoretical idea from Prof. Allen Boozer of Columbia University, the SPARC design includes an innovative new structure which promises fully passive protection from the threat of runaway electrons.
