Future nanoelectronic information storage devices are also tiny batteries – astounding finding opens up new possibilities Resistive memory cells (ReRAM) are regarded as a promising solution for future generations of computer memories. They will dramatically reduce the energy consumption of modern IT systems while significantly increasing their performance. Unlike the building blocks of conventional hard disk drives and memories, these novel memory cells are not purely passive components...
Scientists have developed a way to grow iron-oxidizing bacteria using electricity instead of iron, an advance that will allow them to better study the organisms and could one day be used to turn electricity into fuel. The study will be published on January 29 in mBio®, the online open-access journal of the American Society for Microbiology. The method, called electrochemical cultivation, supplies these bacteria with a steady supply of electrons that the bacteria use to respire, or...
Researchers have developed a self-charging power cell that directly converts mechanical energy to chemical energy, storing the power until it is released as electrical current. By eliminating the need to convert mechanical energy to electrical energy for charging a battery, the new hybrid generator-storage cell utilizes mechanical energy more efficiently than systems using separate generators and batteries. At the heart of the self-charging power cell is a piezoelectric membrane that...

SOUTH WINDSOR, Conn., July 18, 2012 /PRNewswire/ -- UTC Power, a United Technologies Corp. (NYSE: UTX) company, today announced that Pyeongtaek Energy Service, a wholly owned subsidiary of SK E&S, has purchased 14 PureCell Model 400 fuel cell systems. This project will be completed in two phases and aims to be fully operational by the end of 2013. (Logo: http://photos.prnewswire.com/prnh/20120228/NE60332LOGO) The first phase of this project consists of seven PureCell systems...
Material wastes energy, Case Western Reserve University researcher suggests Fuel cells are inefficient because the catalyst most commonly used to convert chemical energy to electricity is made of the wrong material, a researcher at Case Western Reserve University argues. Rather than continue the futile effort to tweak that material - platinum - to make it work better, Chemistry Professor Alfred Anderson urges his colleagues to start anew. "Using platinum is like putting a resistor in...
Some of the planet’s tiniest inhabitants may help address two of society’s biggest environmental challenges: how to deal with the vast quantities of organic waste produced and where to find clean, renewable energy. According to César Torres and Sudeep Popat, researchers at Arizona State University’s Biodesign Institute, certain kinds of bacteria are adept at converting waste into useful energy. These microorganisms are presently being applied to the task, through an innovative...
SOUTH WINDSOR, Conn., July 2, 2012 /PRNewswire/ -- UTC Power, a United Technologies Corp. (NYSE:UTX) company, today announced that CBS Studios will install six PureCell® stationary fuel cell systems at two production locations in California. Three units will be installed at CBS Studio Center, a production facility with 18 sound stages and office space in Studio City, Calif. Three others will be installed at CBS Television City in Los Angeles, Calif., housing eight sound stages and...
New catalyst dramatically cheaper without sacrificing performance Engineers at the University of Wisconsin-Milwaukee (UWM) have identified a catalyst that provides the same level of efficiency in microbial fuel cells (MFCs) as the currently used platinum catalyst, but at 5% of the cost. Since more than 60% of the investment in making microbial fuel cells is the cost of platinum, the discovery may lead to much more affordable energy conversion and storage devices. The material –...

A pH meter, typically consisting of a special measuring probe connected to an electronic meter, is an electronic instrument used to measure the pH (acidity or alkalinity) of a liquid. The probe measures pH as the hydrogen ion activity that surrounds a thin-walled glass bulb at its tip. A small voltage is produce by the probe that measures and displays pH units by the meter. The meter circuit displays voltmeter in pH units instead of volts. The circuit of the pH meter consists of operational...
Count Alessandro Antonio Anastasio Volta was born on February 18, 1745 in Como, Duchy of Milan. At age 39, Volta became a professor at the Royal School in Como in the physics department. A year later, in 1775, Volta invented a device called the electrophorus which generates static electric charges. He marketed his creation so well, that he is often given credit as its inventor. However, a similar machine was documented by Johan Carl Wilcke in 1762. He changed his focus to chemistry in...
