Flexible, low-voltage circuits using nanocrystals-Can be "printed" on ink-jet printers | KurzweilAI

Flexible, low-voltage circuits using nanocrystals-Can be "printed" on ink-jet printers  | KurzweilAI | Material for the 21st century | Scoop.it

University of Pennsylvania researchers have shown that nanocrystals of the semiconductor cadmium selenide can be “printed” or “coated” on flexible plastics to form high-performance electronics.

Electronic circuits are typically integrated in rigid silicon wafers. Flexibility opens up a wide range of applications, but finding materials with the right mix of performance and manufacturing cost remains a challenge.

“We have a performance benchmark in amorphous silicon, which is the material that runs the display in your laptop, among other devices,” said professor Cherie Kagan.

“Here, we show that these cadmium selenide nanocrystal devices can move electrons 22 times faster than in amorphous silicon.”

Next Big Future: Spanish company Graphenano claims Graphene Polymer batteries with triple the energy density of lithium ion and commercialization by end of 2016

Next Big Future: Spanish company Graphenano claims Graphene Polymer batteries with triple the energy density of lithium ion and commercialization by end of 2016 | Material for the 21st century | Scoop.it

Something seems to be moving on the battery front...Graphenano is a Spanish company based in Yecla (Murcia) and they have presented their graphene polymer battery that can largely solve obstacles to the development of the electric car.

They have a partnership with the Chinese company Chint. Chint paid 18 million euros for 10% of the Spanish company.

Grabat Energy, a subsidiary of Graphenano will have a plant in Yecla with 20 production lines. They will produce 80 million battery cells. In this first phase, Grabat will have 200 employees and an investment of 30 million euros, contributed equally by Chint and Graphenano.

The second phase will be much more ambitious. The Chinese company will contribute 350 million euros to Graphenano make a second factory in Yecla. They will form a joint venture to market their products in China. It is expected to have a global revenue exceeding 3 billion and 5,000 employees. They will have batteries for home, mobile, aircraft also produce for bicycles, motorbikes, cars and drones. Grabat has achieved a battery with a range of 800 kilometers and a weight of just 100 kilograms that can be loaded into a conventional outlet only one - third the time required by a lithium-ion-lithium equivalent (which are riding automakers in their electric models). Mario Martinez said in a high-density plug "could be loaded in just five minutes."

Adapted to a car like the Tesla Model S, graphene polymer batteries would increase range from 334 to 1,013 kilometers. In a Nissan Leaf range would increase from 250 to 546 kilometers on a single charge.

Sustainable Plastics: Oxymoronic Greenwash, or the Face of the Future?

Sustainable Plastics: Oxymoronic Greenwash, or the Face of the Future? | Material for the 21st century | Scoop.it

"Plastics is an industry caught between a pretty wretched legacy from an environmental point of view (particularly in terms of the build-up of toxins in the environment generally), and an increasingly inspiring approach to the role of sustainability enhancing plastics in construction, healthcare, agriculture, packaging, electronics, energy and the automotive industry. (To get a sense of what that “innovation pipeline” looks like, have a glance either at Plastics Europe’s “Visions in Polymers” or its “Partner in Sustainable Development” document"

Peel-and-Stick: Fabricating Thin Film Solar Cells on Universal Substrates

Peel-and-Stick: Fabricating Thin Film Solar Cells on Universal Substrates | Material for the 21st century | Scoop.it

Business cards, cellphones and windows could all get a little boost from a sticky new invention. However, fabrication of thin-film solar cells (TFSCs) on substrates other than Si and glass has been challenging because these nonconventional substrates are not suitable for the current TFSC fabrication processes. Researchers have now created thin, flexible solar cells that can stick to paper, plastic, glass and many other materials, just by using double-sided tape.

 

"Now you can put them on helmets, cellphones, convex windows, portable electronic devices, curved roofs, clothing — virtually anything," Xiaolin Zheng, a mechanical engineer at Stanford University who led the development of the new solar cells, said in a statement.

 

The cells are a step toward turning more and more everyday items into either electronics or solar power-harvesting surfaces. Solar cells placed on windows could help a building absorb more solar power than roof installations alone, for example. And a combination of flexible solar panels and electronics could lead to products such as electrified "smart" clothes that control a connected smartphone. With the new peel-and-stick process, the scientists integrated hydrogenated amorphous silicon (a-Si:H) TFSCs on paper, plastics, cell phone and building windows while maintaining the original 7.5% efficiency. The new peel-and-stick process enables further reduction of the cost and weight for TFSCs and endows TFSCs with flexibility and attachability for broader application areas.

Innovation: New CO2-Based Plastics | The Energy Collective

Innovation: New CO2-Based Plastics | The Energy Collective | Material for the 21st century | Scoop.it

rEDUCINGSo many news to post and so little time to do. The blog has earnings news from Solazyme and Amyris, updates from Cereplast, interview article from Ovation Biotech, updates on bio-adipic acid, and of course the weekly news roundup, and now this news from Novomer.

 

We’ll start with this milestone announcement from Novomer, which has developed polypropylene carbonate (PPC) material made from carbon dioxide and propylene oxide, as well as polyethylene carbonate (PEC) made from CO2 and ethylene oxide.

 

Novomer said it just started the world’s first large-scale manufacturing run of PPC polyol producing over several tons of finished product. The PPC polyol was produced at Albemarle’s manufacturing facility in Orangeburg, South Carolina, using existing equipment that was modified for PPC polyol production.

 

Novomer did not disclose the exact annual capacity of the manufacturing facility but according to the company, production from the Albemarle facility is already considered commercial scale for smaller volume polyol applications. Albemarle, a specialty chemical company, will continue to be a manufacturing partner for Novomer using the Orangeburg facility, the company said.

Making Sense of Uncertainty · Resources · Sense about Science

Making Sense of Uncertainty · Resources · Sense about Science | Material for the 21st century | Scoop.it

The guide - supported by JIC - has brought together researchers working in some of the most significant, cutting edge fields. They told us that if policy makers and the public are discouraged by the existence of uncertainty, we miss out on important discussions about the development of new drugs, taking action to mitigate the impact of natural hazards, how to respond to the changing climate and to pandemic threats.

The guide discusses: 

The way scientists use uncertainty to express how confident they are about results.That uncertainty can be abused to undermine evidence or to suggest anything could be true: from alternative cancer treatments to anthropogenic CO2 not changing the atmosphere.Why uncertainty is not a barrier to taking action – decision makers usually look for a higher level of certainty for an operational decision (such as introducing body scanners in airports) than for a decision based on broader ideology or politics (such as reducing crime rates).

Science is not only giving the only and unique answers as 2x2 = 4 but also helps to discuss and categorize uncertainty.
