Better solar cells

In preliminary studies, carbon nanotubes that were engineered into the architecture of semiconductor solar cells (composed of cadmium sulfide, zinc oxide and titanium dioxide) resulted in a doubling of the cells’ photoconversion efficiencies (converting light into energy). In some cases, the efficiency of solar cells jumped from 5 percent to 10 percent in the presence …

Eight american longevity categories

A pdf about eight demographic groups in america with different lifespans. Asian americans live the longest (over 5 years more than average). It is not just money and race. Something very geographic is going on. Something happening locally for lifestyles is a big part. Less alcohol? smoking? How people make a living? Shared ancestry? Brian …

NAND memory capacity doubling every year since 2002

Samsung has new 32-gigabit NAND flash chips that are the first made with circuit elements 40 nanometers wide. These new, smaller chips can be used to make a 64GB card capable of holding 40 DVD-quality movies or 16,000 typical-size MP3 songs. The chip design described on Monday incorporates a new technology called Charge Trap Flash, …

Update on using space rocks as kinetic weapons

I wrote an essay about nanotechnology and future militaries. This is an update with some new links (online impact A series of facts were combined.The facts: 1. Big rocks in space are hard to see. We are still finding things bigger than Pluto. 2. There are a lot of rocks in our solar system. Over …

Nanotubes and nanoparticles help with regenerative medicine

Nanotubes help adult stem cells morph into neurons in brain-damaged rats. When used alone, adult stem cells migrated to healthy areas of the brain. But when combined with nanotubes, adult stem cells not only remained in the brain-damaged regions, they began to differentiate into functioning neurons. The finding could have important implications for the treatment …

Spintronics and quantum computer without superconducting magnets

Physicists at the U.S. Department of Energy’s Argonne National Laboratory have devised a potentially groundbreaking theory demonstrating how to control the spin of particles without using superconducting magnets — a development that could advance the field of spintronics and bring scientists a step closer to quantum computing. The physicists theorize that spin can be induced …

Update on work towards $1000 genome sequencing

Currently it costs about $1,000,000 to sequence the genome.A target is to sequence the genome for $1000 by 2014 (and $10,000 by 2009). In 2005, Jay Shendure used off-the-shelf parts to determine the order of all the DNA bases in a bacterial genome, at 20 times the speed and one-ninth the cost of traditional DNA …

Propellant free Microwave space propulsion

The EM drive engine takes microwave radiation produced by a magnetron and feeds it into a specially shaped resonant cavity. The waves push against the end wall. Because of the difference in wave velocity, being higher at one end that the other, there is a momentum transfer. The result is a measurable net force from …

Harvard University engineers demonstrate laser nanoantenna

It is called a plasmonic laser antenna, the design consists of a metallic nanostructure, known as an optical antenna, integrated onto the facet of a commercial semiconductor laser. “The optical antenna collects light from the laser and concentrates it to an intense spot measuring tens of nanometers, or about one-thousandth the width of a single …
