Researchers have invented nanowire-based battery material that can be recharged hundreds of thousands of times, moving us closer to a battery that would never require replacement. The breakthrough work could lead to commercial batteries with greatly lengthened lifespans for computers, smartphones, appliances, cars and spacecraft. They coated a gold nanowire in a manganese dioxide shell …
Pierre Trudeau was Canada’s Prime Minister from April 20, 1968, to June 4, 1979, and again from March 3, 1980, to June 30, 1984. Pierre Trudeau, who died in 2000, was in power for 15 years.

Each year, manufacturers produce around 5 billion tons of portland cement — the gray powder that mixes with water to form the “glue” that holds concrete together. That’s nearly three-quarters of a ton for every person on Earth. For every ton of cement produced, the process creates approximately a ton of carbon dioxide, all of …
There are calls to start construction on as many as 500 new nuclear reactors domestically in China by 2050, and even more abroad, China could single-handedly more than double the number of reactors worldwide. China will need to build as many as 10-12 reactors a year, roughly double France’s record pace in the 1980s. Experts …
Ad Support : Nano Technology Netbook Technology News Computer Software Vertically-aligned carbon nanotube (CNT) “forest” microstructures fabricated by chemical vapor deposition (CVD) using patterned catalyst films typically have a low CNT density per unit area. As a result, CNT forests have poor bulk properties and are too fragile for integration with microfabrication processing. We introduce a …
Ad Support : Nano Technology Netbook Technology News Computer Software Vietnam plans to mine uranium in the central province of Quang Nam to help support its nuclear power plans. The site targeted in Quang Nam may hold about 8,000 metric tons, while Vietnam’s nationwide uranium reserves may reach into the hundreds of thousands of tons. Vietnam’s …
Ad Support : Nano Technology Netbook Technology News Computer Software ABI Research projects that WiMAX wireless communications will reach more than 1 billion people by the end of 2012, and that LTE will cover another 600 million by that time, marking a fast ramp up of the two technologies that fall into the “4G” category * …
