Graphene ‘spintronic’ devices

The Brookhaven group uses magnetism to manipulate spin in graphene, a material consisting of flat sheets of carbon atoms arranged in a hexagonal pattern. They’ve proposed ways to make materials consisting of layers of graphene mated to magnetic and nonmagnetic layers. These “graphene-magnet multilayers” (GMMs) are expected to retain their properties at room temperature, an …

The first six hours of world war III

Space Wars by William Scott, Michael Coumatos, and William Birnes, Forge Books (April 17, 2007) describes how the first hours of World War III might play out in the year 2010. While fiction, it’s based on real-world military scenarios and technologies, dramatically highlighting the West’s vulnerability to destruction of its space-based commercial and military communications …

Light activated nanoscale scissors from Japan

Researchers in Japan have developed a pair of molecular-scale scissors that open and close in response to light. The tiny scissors are the first example of a molecular machine capable of mechanically manipulating molecules by using light, the scientists say.The scissors measure just three nanometers in length, small enough to deliver drugs into cells or …

Solar sail progress is difficult to assess

Different materials for solar sails with wide variation in capability are all in development. The lighter the sail then the faster it will accelerate. This link has a table which shows the different speeds possible with different accelerations. The carbon nanotube sail has the highest potential. 1 square kilometer 30 kg or 0.03 grams per …

New methods for DNA nanotechnology structures

I think the main benefit for these new methods is to extend the capabilities of these DNA nanotechnology systems along with DNA origami, Ned Seemans DNA systems, rotaxane molecular chemistry, other molecular chemistry, laser/electric manipulation, synthetic biology and advanced self assembly. More tools and methods in our rapidly growing molecular manipulation toolbox. Scientists from Duke …

Improved walking molecule

Walking molecule improved to now carry two molecules of cargo A research team, led by UC Riverside’s Ludwig Bartels, was the first to design a molecule that can move in a straight line on a flat surface. Now this team has found a way to attach cargo: two CO2 molecules, making the nano-walker a molecule …
