Aquion Energy
Aquion Energy was a Bethlehem, Pennsylvania and Washington, D.C.-based company that manufactured sodium ion batteries ( salt water batteries) and electricity storage systems. The company claimed to provide a low-cost way to store large amounts of energy (e.g. for an electricity grid) through thousands of battery cycles, and a non-toxic end product made from widely available material inputs and which operates safely and reliably across a wide range of temperatures and operating environments. History The company was founded in 2008 by Jay F. Whitacre, a professor at Carnegie Mellon University, and Ted Wiley. They set up research and development offices in Lawrenceville, where it produced pilot-stage batteries. The company raised funding from Kleiner Perkins, Foundation Capital, Bill Gates, Nick and Jobey Pritzker, Bright Capital and Advanced Technology Ventures, among others. In 2011, an individual battery stack was promoted to store 1.5 kWh, a shipping container-sized unit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Microgrid
A microgrid is a local electrical grid with defined electrical boundaries, acting as a single and controllable entity. It is able to operate in grid-connected and in island mode.''How Microgrids Work.'' U.S. Department of Energy, June 2014 A 'Stand-alone microgrid' or 'isolated microgrid' only operates and cannot be connected to a wider electric power system. A grid-connected microgrid normally operates connected to and synchronous with the traditional ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sodium Perchlorate
Sodium perchlorate is the inorganic compound with the chemical formula Na ClO4. It is a white crystalline, hygroscopic solid that is highly soluble in water and in alcohol. It is usually encountered as the monohydrate. The compound is noteworthy as the most water-soluble of the common perchlorate salts. Sodium perchlorate and other perchlorates has been found on the planet Mars, first detected by the NASA probe Phoenix in 2009. This was later confirmed by spectral analysis by the Mars Reconnaissance Orbiter in 2015 of what is thought to be brine seeps which may be the first evidence of flowing liquid water containing hydrated salts on Mars. Selected properties Its heat of formation is −382.75 kJ/mol, i.e. it is favorable for it to decompose into sodium chloride and dioxygen. It crystallizes in the rhombic crystal system. Uses Sodium perchlorate is the precursor to many other perchlorate salts, often taking advantage of their low solubility relative to NaClO4 (209 g/100 mL at ...

Intercalation (chemistry)
In chemistry, intercalation is the reversible inclusion or insertion of a molecule (or ion) into layered materials with layered structures. Examples are found in graphite and transition metal dichalcogenides. : Examples Graphite One famous intercalation host is graphite, which intercalates potassium as a guest. Intercalation expands the van der Waals gap between sheets, which requires energy. Usually this energy is supplied by charge transfer between the guest and the host solid, i.e., redox. Two potassium graphite compounds are KC8 and KC24. Carbon fluorides (e.g., (CF)x and (C4F)) are prepared by reaction of fluorine with graphitic carbon. The color is greyish, white, or yellow. The bond between the carbon and fluorine atoms is covalent, thus fluorine is not intercalated. Such materials have been considered as a cathode in various lithium batteries. Treating graphite with strong acids in the presence of oxidizing agents causes the graphite to oxidise. Graphite bisulfate, 2 ...

Cathode
A cathode is the electrode from which a conventional current leaves a polarized electrical device. This definition can be recalled by using the mnemonic ''CCD'' for ''Cathode Current Departs''. A conventional current describes the direction in which positive charges move. Electrons have a negative electrical charge, so the movement of electrons is opposite to that of the conventional current flow. Consequently, the mnemonic ''cathode current departs'' also means that electrons flow ''into'' the device's cathode from the external circuit. For example, the end of a household battery marked with a + (plus) is the cathode. The electrode through which conventional current flows the other way, into the device, is termed an anode. Charge flow Conventional current flows from cathode to anode outside of the cell or device (with electrons moving in the opposite direction), regardless of the cell or device type and operating mode. Cathode polarity with respect to the anode can be positive ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Massachusetts Institute Of Technology
The Massachusetts Institute of Technology (MIT) is a private land-grant research university in Cambridge, Massachusetts. Established in 1861, MIT has played a key role in the development of modern technology and science, and is one of the most prestigious and highly ranked academic institutions in the world. Founded in response to the increasing industrialization of the United States, MIT adopted a European polytechnic university model and stressed laboratory instruction in applied science and engineering.

MIT Technology Review
''MIT Technology Review'' is a bimonthly magazine wholly owned by the Massachusetts Institute of Technology, and editorially independent of the university. It was founded in 1899 as ''The Technology Review'', and was re-launched without "The" in its name on April 23, 1998 under then publisher R. Bruce Journey. In September 2005, it was changed, under its then editor-in-chief and publisher, Jason Pontin, to a form resembling the historical magazine. Before the 1998 re-launch, the editor stated that "nothing will be left of the old magazine except the name." It was therefore necessary to distinguish between the modern and the historical ''Technology Review''. The historical magazine had been published by the MIT Alumni Association, was more closely aligned with the interests of MIT alumni, and had a more intellectual tone and much smaller public circulation. The magazine, billed from 1998 to 2005 as "MIT's Magazine of Innovation," and from 2005 onwards as simply "published by MIT", ...

WARN Act
The Worker Adjustment and Retraining Notification Act of 1988 (the "WARN Act") is a U.S. labor law that protects employees, their families, and communities by requiring most employers with 100 or more employees to provide 60 calendar-day advance notification of planned closings and mass layoffs of employees. In 2001, there were about 2,000 mass layoffs and plant closures that were subject to WARN advance notice requirements and that affected about 660,000 employees.The Worker Adjustment and Retraining Notification Act: Revising the Act and Educational Materials Could Clarify Employer Responsibilities and Employee Rights: Report to Congressional Requesters U.S. Gove ...
