from MIT’s Technology Review:
It is inevitable that eventually Moore’s Law will fail–at least for silicon technology. Further miniaturizing silicon transistors to fit more of them on a microchip will become impossible, or at least too expensive. Researchers are anticipating that day by developing alternative materials such as gallium arsenide, graphene, and carbon nanotubes.
The hope is that transistors made from these materials will be smaller, faster, and more energy efficient than anything that could ever be made from silicon. “We need to add more materials to the toolbox,” says Michael Mayberry, director of components research at Intel.
Pure awesomeness from MIT:
A team of MIT researchers has found a novel way to mimic the process by which plants use the power of sunlight to split water and make chemical fuel to power their growth.
In this case, the team used a modified virus as a kind of biological scaffold that can assemble the nanoscale components needed to split the hydrogen and oxygen atoms of a water molecule.
Splitting water is one way to solve the basic problem of solar energy: It’s only available when the sun shines. By using sunlight to make hydrogen from water, the hydrogen can then be stored and used at any time to generate electricity using a fuel cell, or to make liquid fuels (or be used directly) for cars and trucks.
from NEXT BIG FUTURE:
What looks possible by 2020 if the research from five different research groups can be combined ?
Here is the five things to combine-
1. Montreal researchers have created computer controlled bacteria to make nanopyramids.
Magnetic nanoparticles under computer control – determine how the cilia operate.
2. Other researchers have placed 3 micron X 3 micron by half a micron chips inside living cells and
3. in the same article as number 2 other researchers have used magnetized nanoparticles to control cells and hold them in desired positions and shapes
4. From the exclusive nextbigufuture interview with an executive from Tilera, a company that makes One hundred core CPUs that use 7 times less energy for the same processing power as Intel chips.
Tilera forecast making 3D cube chips with 1000 cores by 2020.
5. Memristor-CMOS hybrid chips are close – probably first one commercial within 3 years.
from MIT’s Technology Review:
[…] Wang has been developing devices based on nanowires that exhibit piezoelectricity. That is, they generate a voltage when they’re bent.
He has been integrating these nanowires into devices that can harvest energy from biomechanical motion–including the running movements of a hamster on a wheel or the tapping of a finger–and use it to power a small sensor.
By using a computer-controlled magnetic field, the researchers turned the bacteria into fully-compliant biological nanorobots.
The trick was using a type of microbe known as magnetotactic bacteria. These critters have little internal compasses, and will follow the pull of a magnetic field. By manipulating a magnetic field, the researchers tricked the bacteria into forming a giant, computer-controlled swarm.
from Tel Aviv University (via Machines Like Us)
Prof. Yael Hanein of Tel Aviv University’s School of Electrical Engineering has foundational research that may give sight to blind eyes, merging retinal nerves with electrodes to stimulate cell growth.
She’s developed a spaghetti like mass of nano-sized (one-millionth of a millimetre) carbon tubes, and using an electric current has managed to coax living neurons from the brains of rats to grow on this man-made structure.
