To connect intermittent renewable energy sources (i.e., Sodium is seen by some as a promising alternative, but the sodium-sulfur batteries currently in use run at temperatures above 300 °C, making them less energy efficient and safe than batteries that run at ambient temperatures. Earlier post.) for some time. performance.
Researchers at Chalmers University of Technology, Sweden, have developed a nanometric graphite-like anode for sodium ion (Na + storage), formed by stacked graphene sheets functionalized only on one side, termed Janus graphene. The estimated sodium storage up to C 6.9 100 to 150 mA h g ? 100 to 150 mA h g ?1
Researchers at the University of Maryland have developed a nanocomposite material of amorphous, porous FePO 4 nanoparticles electrically wired by single-wall carbon nanotubes as a potential cathode material for sodium-ion batteries (SIBs). SWNT composite is a promising cathode material for viable sodium-ion batteries.
In October 2008, Xcel began testing a one-megawatt sodium-sulfur (NaS) battery ( earlier post ) to demonstrate its ability to store wind energy and move it to the electricity grid when needed. The battery installation is connected to a nearby 11-megawatt wind farm owned by Minwind Energy, LLC. A final report is expected in summer 2011.
Swedish sodium-ion battery developer Altris presented a pure Prussian White cathode material with a capacity of 160 mAh/g, making it the highest capacity declared to date. Prussian White is a framework material consisting of sodium, iron, carbon and nitrogen (Na x Fe[Fe(CN) 6 ] with x>1.9). Earlier post.)
A team from the Max Planck Institute for Solid State Research in Stuttgart and the University of Science and Technology of China, Hefei, has developed a high-power, high-capacity sodium battery with 96% capacity retention after 2,000 cycles. 2016), “High Power–High Energy Sodium Battery Based on Threefold Interpenetrating Network.”
Researchers from the US and Sweden have shown that carbon nanostructures (fullerenes, nanotubes, and graphene) can be used as catalysts for hydrogen uptake and release in complex metal hydrides such as sodium alanate (NaAlH 4 ) and also developed what they characterize as an “ unambiguous understanding ” of how such catalysts work.
A team of researchers from Northwestern University, UCLA and the University of St. The nodes of the lattices are complexes of transition metals (such as copper, zinc, nickel, or cobalt); organic molecules make up the connections between the nodes.

Researchers at WMG (Warwick Manufacturing Group), The University of Warwick (UK) have developed Silicon-Few Layer Graphene (Si-FLG) composite electrodes as an effective approach to replacing graphite in the anodes of lithium-ion batteries. Source: WMG. Click to enlarge. A cross section of the silicon and FLG together in an anode.
In partnership with a consortium of local research institutions, this project deploy smart grid systems at partners’ university campus properties and technology transfer laboratories. Demonstration of Sodium Ion Battery for Grid Level Applications. (DOE funding $75,161,246, total project value with cost share $150,322,492). 10,792,045.
Researchers at Northwestern University , Evanston, Ill., and the University of Sussex , Brighton, England, have created prototypes of new environmentally sustainable devices that can monitor blood pressure and heartbeat, or heal persistent afflictions such as diabetic ulcers.
is building two fast-neutron nuclear breeder reactors, the first of which is slated to connect to the grid in 2023, the second in 2026. China is in the middle of a big buildup of its nuclear-weapon arsenal,” says Frank von Hippel , a physicist and nuclear-policy expert at Princeton University. “My It is anything but.
A team at the Ohio State University has developed a membrane that regulates bi-directional ion transport across it as a function of its redox state and that could be used as a programmable smart membrane separator in future supercapacitors and redox flow batteries. B) PPy(DBS) is formed over a porous substrate spanning the pores.
In a review paper in the journal Nature Materials , Jean-Marie Tarascon (Professor at College de France and Director of RS2E, French Network on Electrochemical Energy Storage) and Clare Gray (Professor at the University of Cambridge), call for integrating the sustainability of battery materials into the R&D efforts to improve rechargeable batteries.
In other words, you had incandescent light bulbs at home, and you had fluorescent lights in your office and sodium lights on the streets, and nothing really changed very much. LEDs offer benefits over older light sources, which is why they’ve been fast-tracked into near-universal use via government-mandated performance standards.
Purdue University, West Lafayette, Ind. Low Cost Roll-to-Roll Manufacturing of Reusable Sorbents for Energy and Water Industries, $150,000 Qualification of SAS4A/SASSYS-1 for Sodium-Cooled Fast Reactor Authorization and Licensing, $674,484 Advanced Reactor Concepts LLC, Chevy Chase, Md. Combustion Research & Flow Technology Inc.,
We start with a Bose-Einstein condensate, 1 million sodium atoms that share one and the same quantum-mechanical wave function”, says Martin Zwierlein , a professor of physics at MIT. Of course there can; the universe is quantum. Rick Duffy/Wikipedia. Successive frames in a movie can be captured by a well-placed CCD camera.
Software also allows for the decoupling of the internal mechanical connections needed in an ICE vehicle, permitting an EV to be controlled remotely or autonomously. An added benefit is that the loss of the ICE powertrain not only reduces the components a vehicle requires, but also frees up space for increased passenger comfort and storage.
Its lab tests revealed that most were variations of salt mixtures, such as sodium and magnesium sulfates. percent sodium sulfate (Glauber’s salt, a horse laxative) with the remainder being water of hydration (water that’s been chemically treated to form a hydrate). National Bureau of Standards stepped in.
It’s got sodium, potassium, calcium, etc., It doesn’t really like sodium so much. This was work from Denis Jabaudon at the University of Geneva, and they were looking at how neurons actually differentiate. Adee: Well, so Michael Levin is a professor at Tufts University. This is like sieve water.
