The Eetimes recently discussed another candidate technology for molecular electronics. Monomeric phthalocyanines could be organized into one dimensional wire-like ring-stacked or two dimensional sheet-like ring-fused phthalocyanines to make fully reversible quantum switch with multiple outputs. CTT, the company that bought the rights to the technology, is only a 27 million market cap company. Although they …
The upside is that smog levels declined nationwide between 2003 and 2005, aided by the appearance of more pollution controls on smokestacks, according to the report, called “State of the Air: 2007.” The bad news is that the number of places in the United States reporting unhealthy levels of soot grew over the same period, …
Engineer-Poet analyzes the H2CAR proposal and shows why it is a misleading diversion from real solutions H2CAR is completely unaffordable. In the H2CAR paper, figures such as 239 billion kg/year of hydrogen from 58,000 km2 of solar PV panels are tossed off rather casually. These numbers bear deeper analysis than they receive. For instance, 58,000 …
Researchers in Italy have created an ultrashort light pulse—a single isolated burst of extreme-ultraviolet light that lasts for only 130 attoseconds (billionths of a billionth of a second). Their achievement currently represents the shortest artificial light pulse that has been reported in a refereed journal. Shining this ultrashort light pulse on atoms and molecules can …
Pessimistic timetables for commercializing the rapid fire are 30 years or more. However, one of the skeptics is Ian Hutchinson who is a strong supporter of the Tokomak ITER (International Thermonuclear Experimental Reactor) project. Even if money were no object, it could take 30 years to build a system, says Keith Matzen, director of pulsed …
Samsung Electronics announced today that it has become the first to begin mass producing 16 gigabit NAND flash, the highest capacity memory chip now available. The company said it will fabricate the devices in 51 nanometers, the finest process technology to be used in memory mass production to date. Samsung’s 51nm NAND flash chips can …
Inexpensive, brain wave activity sensors, are being used for video game controllers NeuroSky worker Cynthia Lee wears one of their head sets at NeuroSky headquarters in San Jose, Calif., Tuesday, March 27, 2007. The startup company aims to add more realistic elements to video games by using brain wave-reading technology to help game developers make …
The world is building a lot of coal-fired power to go with all of the coal-fired power it already has. This is horrible because air pollution from coal kills more than one million people every year. We need to use all other means to reduce the increase in coal usage, this means more nuclear as …
