Holy graphene: Giving batteries a boost with graphene and tiny holes

Holy graphene: Giving batteries a boost with graphene and tiny holes | Innoveering | Scoop.it
A Midwest startup wins a big business plan competition by showing the promise of its technology to create a longer-lasting lithium ion battery that also can charge at a faster rate than what batteries in smart phones can deliver today.
csbishop's insight:

Graphene will allow electricity to flourish. Battery life has been a severe weakness to thoughts of a fully electric lifestyle. Now, we gonna rock down to Electric Avenue.

Innovators Dilemma Author Clayton Christensen Discusses Disruption via Startup Grind [Video]

Disruption In BSchool Education

Most of this talk is about disruption in education, but Christensen is the "master of disruption" and this conversation with Mark Suster is fascinating for Internet marketers.

Lack of technological core means an industry can't be disrupted. Education was in this boat for a long time. Online learning brings to education a "technological core" matched with pricing that has lost touch with reality means disruption is possible and likely.

Online learning and corporate learning programs are killing Harvard Business School. Christensen says half of the University business schools are in trouble and will be forced to get with it or close in ten years.

Apple Computer
Fascinating discussion of Apple & proprietary architecture at 10:33. The inevitable opening of a once proprietary operating system means prices fall and the money is made in "sophisticated manufacturing". "It really is scary," says Christensen about the loss of sophisticated manufacturing.

He goes on to blame business school for looking to layoff costs because of the way we teach people to measure things.

Freemiums
Another fascinating conversation about Fremiums at 14:30. "As a general rule if you have a product that doesn't get the job done you have to offer it for free," with Suster weighing in on charging for services. Modularity drives commoditization and that drives profit out.

Crowdfunding
Free usually means there is money to be made, "Above and below and you can invest or be an entrepreneur there and you can make money". Suster then talks about Venture Capital disruption and crowdfunding at 19:50.

Royalty Capital
Royalty Capital = movement in Boston to license capital as a way around limitations of venture capital at 24:00. When revenue starts there is a royalty rate returned to the capitalists. Fascinating alternative financing experiment going on in Boston.

Graphene Becomes Magnetic for First Time

Graphene Becomes Magnetic for First Time | Innoveering | Scoop.it

Researchers from both the University of Madrid Complutense and the Universidad Autonoma working together at the IMDEA-Nanociencia Institute in Spain have for the first time given graphene magnetic properties, opening up the potential that the material can find new applications in future spintronic devices. Unlike electronics in which an electron’s charge-carrying capabilities are exploited to create circuits, spintronics involves the quantum mechanical property of electrons to spin, which creates a magnetic moment that makes the electrons behave briefly like magnets. When in the presence of a magnetic field the spin of the electrons moves either into a parallel or antiparallel position in relation to the field. This positioning can be translated into a binary signal.

 

The trials and tribulations trying to make graphene applicable to electronics despite its lack of an inherent band gap have been well documented. However, what many have overlooked in the quest to bring graphene to electronics is that it doesn’t really lend itself very well to spintronics either. Since 2007, researchers have looked at graphene as the material for channels in spintronic devices. At this function, it appears to excel. In fact, just this yearrecord distances were achieved for carry information using the spin of electrons.

 

Unfortunately, when two-dimensional graphene is laid out flat, the motion of electrons moving through the material doesn’t influence the spin of other electrons that they pass. Instead the direction and the spin of electrons remain random rather than patterned. More than two years ago, researchers at the University of Copenhagen discovered that that all changed if you curved the graphene into a cylinder. In that shape, the movement of electrons did influence the spin of other electrons, opening the door to their potential in spintronics.

 

In order for a material to be have magnetic properties a majority of the electrons in the material must be spinning in the same direction. Despite the work of the Copenhagen researchers and many others, it has remained a challenge to get graphenes’ electrons to spin in the same direction instead of just randomly. But the Spanish researchers believe they have accomplished it.

 

“In spite of the huge efforts to date of scientists all over the world, it has not been possible to add the magnetic properties required to develop graphene-based spintronics. However these results pave the way to this possibility," says Prof. Rodolfo Miranda, Director of IMDEA-Nanociencia, in a press release.

 

The research, which was published in the journal Nature Physics ("Long-range magnetic order in a purely organic 2D layer adsorbed on epitaxial graphene"), first grew ultra pure graphene film over a crystal inside of a vacuum. While still in the vacumm, the researchers evaporated molecules of a semiconductor on the graphene’s surface. When they observed the material with a scanning tunneling microscope, they were surprised to discover that the semiconductor molecules were organized and regularly distributed across the surface of the graphene and its crystal substrate.

 

Since spintronics hasn't really progressed beyond its application into devices beyond hard-disk drives, the ability to give graphene magnetic properties likely won't bring spintronic devices into other applications any sooner. But these kinds of breakthroughs do have a way of opening up unexpected possibilities.

Scientists Create Sensor As Sensitive As Real Skin

Scientists Create Sensor As Sensitive As Real Skin | Innoveering | Scoop.it

While prosthetic limbs continue to improve, tactile feedback is one feature that many are keen to incorporate into the prosthetics but it remains a very difficult technology to develop. But now scientists have developed a new device so packed with sensors it is about as sensitive as human skin. Just as Moore’s Law continues to benefit the integrated circuit, packing ever more sensors into a smaller area will allow such devices to one day be built into everything we touch.

Some areas of our skin, like the lips and fingertips, are more sensitive to the touch because of a greater density of receptors that translate mechanical force into neuronal signals. The sensory device built by scientists at Georgia Tech is a new kind of transistor that converts mechanical force into electricity. The force bends nanoscale wires made of zinc oxide. When the wires bend back, zinc and oxide ions create an electrical potential that is converted to electrical current of a few millivolts. Converting mechanical energy to electrical energy is known as the piezoelectric effect.
